The present invention provides a door opening and closing operation means for opening and closing the main door of the garage, the main detection means for detecting the opening and closing state of the order, the opening of the window or the auxiliary door of the garage or the generation of fire or special gas in the garage. Auxiliary detection means for detecting a warning means (경보 知 手段), signal processing means and the like is provided to control the operation means and the alarm means for opening and closing the door by logically judging the electric signal from each detection means.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garage door opening and closing device, and more particularly, to a garage door opening and closing control device capable of precise process control by detecting an abnormal state in a garage.

Conventionally, a garage door opening and closing control apparatus for driving and opening a garage door by a motor has been proposed. The motor is connected to a power supply via a relay circuit controlled by a pushbutton switch for command or a radio control switch to drive the door in a predetermined direction. Such a motor drive door control device is disclosed in the specification of US Patent 3,178,627 (Patent: 1965.4.13, inventor Richard D, Houk) or 3,906,348 (Patent: 1975.9.16, inventor: Colin B. Willmott).

In general, the garage is often used as a place to store various miscellaneous items in addition to functions as a garage. For this reason, sufficient surroundings are required for fire accidents and theft prevention. In order to detect such a fire accident or theft prevention, for example, a temperature detection type or a smoke detection type fire accident detection device, a light shielding type, a lead switch type, or an anti-theft type anti-theft device is commercially available. However, if you buy such a pre-installed device and install it in the garage, the following bad condition occurs.

1. Since abnormal state detection devices such as fire accident detection device and theft prevention device and door opening / closing control device are installed separately, there is little effect of preventing accidents and reducing the damage regardless of mutual operation.

2. It is uneconomical because abnormal state detection device such as fire accident detection device or theft prevention device and door opening / closing control device are installed separately and several parts having the same function are used.

3. As the abnormal state detection device such as fire accident detection device or theft prevention device and the door open / close control device are installed separately, the power supply wiring needs two openings, which makes the wiring work complicated and the input of the power switch is difficult. It is troublesome.

SUMMARY OF THE INVENTION An object of the present invention is to propose a garage door opening and closing apparatus that can open and close a garage door well by controlling the operation of the garage door and the processing by the abnormal state detection in the garage.

Features of the present invention include door opening and closing operation means for opening and closing the door of the garage, main detection means for detecting the opening and closing state of the door, opening of the window or auxiliary door of the garage or the generation of fire or special gas in the garage, etc. An auxiliary detecting means for detecting, an alarming means, a signal processing means, and the like are provided to logically judge an electric signal from each detecting means to control the door opening and closing operation means and the alarming means.

As shown in FIG. 1, the garage door opening and closing apparatus of the present invention is guided by the main body 1 incorporating a driving device, the rail 2 connected to the main body 1, and the rail 2, and the main body ( It is made as a main part of the trolley 4 which is fixed to the roller chain 3 which operates by the driving force of 1), and moves horizontally. The main body 1 is suspended from the ceiling of the garage as a hanging bracket, while the end of the rail 2 is fixed to a part of the garage by a header bracket 5.

On the other hand, the garage door 6 is generally divided into purchases and connected to each other and opened and closed along the door rails 7 provided on both sides. And the weight of this garage door 6 is balanced by the door balance spring 8, and it is in the state which can be opened and closed by manpower.

The door bracket 9 is fixed to the garage door 6 in the above state, and the door bracket 9 and the trolley 4 are pivotally connected via the door arm 10. The garage door is thereby equalized to the roller chain 3 which is operated by the driving force of the main body 1 and the trolley 4 which is horizontally moved along the rail 2 by the operation of the roller chain. It is opened and closed along 7). Power supply to the main body 1 is performed via a power cable 11.

The operation command to the main body 1 is operated by the main body 1 by pressing the pushbutton switch 12 mounted on the wall of the garage or by receiving a signal by a control device 13 incorporating a receiver. Output the command. In addition, if the garage door opening and closing device becomes inoperable due to a power failure lamp, the connection between the roller chain 3 and the trolley 4 is released by the release string 14, and the garage door 6 is opened by manpower. I can open and close it.

2 and 3, the main structure of the garage door opening and closing device will be described. 2 is a longitudinal side view and FIG. 3 is a partial cross-sectional top view.

Rotation of the motor 16 fixed to the lower side of the main frame 15 is performed by the motor pulley 17, the V belt 18, and the large pulley 19 fixed to the motor shaft 16-a. Is passed on.

The rotation of the large pulley 19 is transmitted to the sprocket 21 via the sprocket shaft 20. The roller chain 3 is meshed with this sprocket 21. The roller portion of the roller chain 3 is guided by the chain guide A22, the chain guide B 23, and the chain guide C24 from both sides in the main body plane 1.

The rail 2 is fixed to the plane 15 by a rail fixing bracket 25 without grooves and steps and gaps formed by the chain guide A 22 and the chain guide C 24. do. The roller parts of the roller chain 3 are guided by rails 2 on both sides.

On the other hand, the housing of the roller chain 3 wound up by the sprocket 21 is a chain fixed with no groove and a step formed with a chain guide A 22 and a chaise guide B 23 without step and gap. It is performed by the chain storage opening 27a of the storage case 27.

By the above structure, the sprocket 21 is rotated by the rotational drive of the motor 16, and the rotor chain 3 moves reciprocally along the rail 2. As shown in FIG.

Next, a limit mechanism for limiting the upper and lower limits of the opening / closing operation of the garage door 6 described as FIG. 1, that is, the horizontal movement amount of the trolley 4 will be described below.

The amount of movement of the roller chain 3 is converted into the amount of movement of the pulley rack 28 provided on the outer periphery of the large pulley 19 which rotates at the same rotational speed as the sprocket 21. The amount of movement of the pulley rack 28 is transmitted to the upper limit switch 30 and the lower limit switch 31 via the pinion 29 engaged with the pulley rack 28.

A lower limit adjustment knob 32 and a lower limit adjustment knob 33 are provided on each of the upper limit limit switch 30 and the lower limit limit switch 31, whereby the upper limit point and the lower limit point can be freely adjusted outside the main body. Let's do it.

If the garage door touches an obstacle during the descent, it should be quickly detected for safety and reverse operation, ie, an increase. If the garage door touches an obstacle during the lift, the garage door must be detected quickly and stopped for safety.

The obstacle detection mechanism described above will be described below. A part of the chain guide opening formed in the chain guide (C) 22, the chain guide (B) 23, and the chain guide (C) 24 is formed into a curved path, and the door is connected to the roller chain 3. The obstruction detecting bracket 34 which moves in accordance with the force generated by each of the extrusion force applied when descending and the tensile force applied when the door is raised is provided. The spring pressing plate 37 can be moved and changed freely by rotating the compression force of the obstacle spring 35 which restricts the movement of the obstacle inspection tool 34 and by turning the operating force adjusting screw 36. In addition, the above-mentioned obstacle detection switch 52 detects the above-mentioned obstacle by the obstacle detecting switch 52 which is turned on and off by the movement of the obstacle detecting hole 34, and when the door descends, it stops.

In addition, a lamp 38 for lighting in the garage is provided to interlock with the movement of the garage door so as to turn on and off the lamp. Then, the motor 16 and the controller 39 for controlling the lamp are fixed in the foil 15 and the main body 40, the lamp cover 41, and the motor 16, the pulley 19, the lamp. (38) is covered. Since the lamp lamp 41 is translucent, light of the lamp 38 is transmitted to illuminate the inside of the garage brightly.

The structure of the main body of the garage door opening and closing apparatus has been described above. Next, the rail and the trolley portion will be described with reference to FIGS. 4 and 5. The cross-sectional structure of the rail (2) is formed of a thin iron plate or plastic plate, to guide the trolley (4) in the outer peripheral portion of the rail sliding. The rail 2 guides the roller portion of the roller chain 3 between the two shaft surfaces so as to linearly reciprocate the roller chain 3. Next, this trolley coupling is performed by attaching a pin 4-c to the trolley 4 and inserting the pin 4-c into the tool 4-b. This pin 4-c is normally pressed by the spring etc. in the state shown in FIG. This is to absorb the shock when the obstacle collides with the obstacle while the door is descending. In addition, the garage door opening and closing device requires measures to prevent the gate from being reversed when the door descends, even when the floor surface is raised by snow or ice, or when there is a small object such as a water hose. Do. In other words, it is necessary to stop at 2 inches or less above the floor without reversing even if an obstacle is detected. In this case, the difference in the amount of movement between the trolley 4 and the door 6 is absorbed by this tool 4-b.

6 is a state transition diagram showing the basic operation sequence of the garage door of the present invention. 6, the garage door 6 is in a stopped state 303 after the power is turned on. Whenever the operation terrain is received by this state, the garage door 6 repeats the up state 300, the stopped state 301, the down state 302 and the stopped state 303.

Apart from such an operation command, if there is an input from the upper limit limit switch 30 in response to the garage door 6 in the elevated state 300, the state 307 quickly moves to the stopped state 301 via the state limit 307. do. If there is an input from the lower limit limit switch 31 in response to the garage door 6 in the lowered state 302, the state shifts to the fixed time lowered state 304 via the state 309, After a lapse of a predetermined time, a stop state 303 is obtained.

The detailed explanation about the reason for this time descending is mentioned later. In order to safely operate the garage door 6, a description will be given of the case where the movement of the garage door 6 is prevented. When the garage door 6 is in an elevated state and there is an obstacle detection input, the state of the garage door 6 is quickly changed to the stopped state 301 via the state 308. If the garage door 6 is in the lowered state 302, and there is a fault detection input, the state shifts to the stationary state 305 once via the state 310, and after 1 hour, the rising state 306 ).

This one-foot rise is time controlled and transitions to the stopped state 301 after the elapsed time. Here, when there is an input from the upper limit limit position 30 on the way in the 1 foot up state, the signal from the upper limit limit switch is first processed, and then the state transitions to the stop state 301 quickly.

The reason why the time decreases will be described below.

In general, the bottom surface of the door in winter is likely to fluctuate due to freezing or snow. If the bottom surface is changed more than the initial setting and rises for the above reason, the obstacle detecting switch 52 is always operated when the door is lowered, so that the door 310 can be closed. For this reason, in this embodiment, the lower limit limit switch 31 is operated in the state before the whole door, and the door is closed by the subsequent time descending after that. If there is an input from the lower limit switch 31, the fault detection input is ignored. By doing in this way, even if the bottom surface of the lower end part of a door changes, it will not affect opening and closing of a door. And the lower limit adjustment becomes easy (to fully satisfy US standard UL 325.27. 1 description), the door operability is remarkably improved.

Specifically, the lower limit switch 31 is adjusted to operate at a height of 2 inches from the bottom surface so that the door is sufficiently closed in the sixth timed descent state 304. However, if the fault detection switch 52 operates in the timed descent state 304, the fault action is first processed, and the state is quickly shifted to the stop state 303. By doing in this way, the pressing force with respect to the obstacle within 2 inches to a floor is relieved.

The detailed description regarding the garage door control of this invention mentioned above is demonstrated using FIG. 14-37 of the process flowchart mentioned later.

7 shows a basic block diagram of the control unit, which is composed of an input circuit 312, a logic processing circuit 311, and an output circuit 313. The input circuit 312 is an interface circuit having a signal level replacement function generally referred to. The circuit includes an upper limit limit switch 30, a lower limit limit switch 31, and a fault detection switch 52 indicating various states of the garage door 6. In addition to signals such as a signal, a signal such as a pushbutton switch 12 or a receiver 330 for radio control is input as a signal for operating the garage door 6. This signal is most appropriately processed according to the processing steps stored in advance in the logic processing circuit 311, and the result is output. The output circuit 313, to which the output signal is input, amplifies the output signal to perform the inversion control of the motor 16, the ON-OFF control of the in-garage lighting lamp 38, and the like.

8 illustrates the basic block diagram as an example.

In the present embodiment, the control device 13 incorporating a receiver incorporates the entire signal processing unit centering on the logic processing circuit 311.

The main body 1 includes a motor 16, a driving portion and a lighting portion made of a lamp 38, and a driver circuit for driving the component, specifically, a transformer 314, a motor drive circuit 327 made of a relay, 328, a lamp drive circuit 329 made of a relay is incorporated. The control device 13 and the main body 1 are connected by eight wires.

The primary power source 115V supplied by the power source code 11 is stepped down to AC14V by the transformer 314 and is voltageified to DC10V in the constant voltage circuit 315 to become a circuit voltage.

The outputs of the upper limit limit switch 30, the lower limit limit switch 31, and the fault detection switch 52 are input to the interface circuits 317, 318, and 319 composed of resistance-capacitors, so that their circuit output Each is input to the logic processing circuit 311.

The operation pushbutton switch 12 is input to an interface circuit 320 composed of a resistor-capacitor, and the circuit output thereof is input to the logic processing circuit 311.

The output of the logic processing circuit 311 is input to the drive circuit 322 constituted by the transistor to drive the drive circuit 327 constituted by the relay in order to forward rotate the motor 16. In addition, the drive circuit 323 configured as a transistor drives the drive circuit 328 configured by the relay to input the output of the logic processing circuit 311 to reverse the motor 16.

In addition, the drive circuit 329 composed of a relay as a drive circuit for turning on and off the lamp 38 is driven by the logic processing circuit 311 via a drive circuit 324 composed of a transistor for driving the relay. .

In addition, as the output circuit of the non-processing circuit 311, there is a door indicator circuit 325 and an alarm circuit 326 for displaying the state of the garage door 6, which will be described later.

The push button switch 12 is a door operation switch mounted on the case of the control device 13, but there is a radio control operation command system that separately applies a transmission and reception function. This is for manipulating doors from the garage and using UHF band radio waves. In operation, the bit setting unit built into the transmitter 331 and the bit setting circuit 321 in the control device 13 are matched first. As the information transmitted from the transmitter 331, this set bit information part is sent sequentially.

Details of the information format will be described later. The sent information is demodulated by the receiving circuit 330, binarized, and input into the logic processing circuit 311. As the main configuration of the receiving circuit described here, a super reproducing circuit (generally called a spatizer) is adopted.

The sent information is sequentially compared with the contents of the bit setting circuit 321, and if all bits match, it is processed as an operation signal as a ratio. Of course, if the bit settings are different, it is impossible to operate the garage door.

In addition, there is a function for setting the lighting time of the lamp 38 and an interface circuit 316 of the abnormal state detection input signal in the garage.

Next, the configuration of the logic processing circuit 311 will be described with reference to FIG. A program memory circuit 340 (in general, READ ONLY MEMORY = ROM is written) in which the processing sequence is programmed and stored in advance in order to control the garage door 6 most appropriately, and this program memory circuit ( An instruction register 341 which temporarily stores the instruction code protruding from the 340, and an instruction decoder 342 for decoding the contents of the instruction code stored in the instruction register, and controls the operation timing of the instruction code and the entire circuit. Get to

There is a program counter 343 in order to designate the address of the instruction code in the program memory circuit 340 and to update the address. The program counter 343 is connected to a stack register 344, which is a register used for storing the return address, for example, during a skip process (e.g., a western routine jump) in the program.

And a logical operation circuit 345 for racking logical operations such as binary addition, a status display register 346 for temporarily storing the result of the logical operation result, a register 347 such as an accumulator used for logical operation, and an operation. Temporary memory 349, such as storing the result or status flag (e.g., how the door is now, running: 1, stopping: 0), (this temporary memory circuit 349 is generally RANDOM ACCESS MEMORY = The buffer register 348 is addressed by the logical operation circuit 345 with RAM writes, and the individual main circuits are connected by bus lines 352. An input / output circuit 350 is connected to the bus line 352. The input / output state input through the bus line 352 is configured by a logic operation circuit 345 and a register 347 state display register 346. Process by the determination means.

With reference to FIG. 10, the temporary memory circuit 349, which plays an important role in proceeding with the processing in the above configuration, will be described as an example.

As described above, the temporary storage circuit 349 is used for storing the result of calculation and temporarily storing the status flag. The unit to be stored is 4 bits 2 bytes. In the embodiment of the present invention, there is a map area of 22 bytes. As the above state flags, three bytes of 0, 1, and 2 are allocated, and the meanings of the individual flags are explained in a flowchart to be described later.

12 bytes of 10-21 are used as timer elements. The basis of the timer group is the basic timer TM1 and 15.625 msec in this embodiment. Since the processing step time of one program is already known, a certain number of steps is counted and adjusted to it. That is, in one embodiment of the present invention, a timer system composed of an external hard is not used at all. The state flagter and the immersion group are updated in sequence in the processing step, and the logical operation circuit 340 makes a logical decision based on the contents and the instruction code stored in the program storage circuit to determine the optimum program processing.

Next, the operation procedure of the garage door of this invention is demonstrated concretely.

The operation transition diagram of the garage door has already been described with reference to FIG. 6, but before describing the flowchart, items to be noted in the processing contents are described.

1) Discontinuous Input Signal Control

Identifies whether the input signal from the operation pushbutton switch or the reception diagram is a new signal or a continuous signal from before. In this method, the timer TM4 is set after the input signal is turned off, and if there is an input signal again before the timeover, it is treated as continuous, and after the timeover, it is processed as a new input signal. The input signal before the former timeover is set again by the timer TM4 after the signal is turned off. Moreover, in the Example of this invention, in order to improve operability, it is as follows.

1. When the door starts to operate, a condition occurs that you want to stop the door immediately. For example, there is an obstacle in the direction of movement of the door. Therefore, 0.25 seconds was adopted as the discontinuous time TM4 value at which the door was operating.

2. If the door is restarted after stopping, it is necessary to take sufficient time to stop the drive or the door to reduce the large impact load. The experiment confirmed that the rotational inertia of the motor disappeared for about 10 minutes at about 0.15 seconds, and 0.5 seconds was used as the discontinuous timer TM4 value of the stop of this door.

2) Start count control

Motors used in garage doors are generally of short-term ratings, and the thermal switch 192 in the motor is activated after several consecutive operations. As a result, if the housing of the motor is not cooled, the thermal switch does not return and the garage door operation is disabled for a period of about 20 minutes. In addition, the above state is difficult to occur in a normal use state and is often caused by mischief by a child or the like.

In particular, if there is a mischief by a child or the like, and the thermal switch is constantly operating, the life of the motor may be reduced, which is not preferable, and may lead to a serious accident. As a scheme for preventing it, a start recovery control algorithm as shown in Fig. 11 is employed.

1. Set the 2-minute timer TM ₁₀ after the door has stopped.

2. When the restart operation command is input (for example, I state) while the TM ₁₀ is not time out, the ED counter (startup counter) is added.

3. The AS and the ED counters when the time TM ₁₀ OY server restart operation instruction is inputted after (for example Ⅱ state).

4. When the restart operation command is not input (for example, in the III state) within 6 minutes after the door stops, the ED counter is cleared. This timer is TM ₁₁ . If the ED counter touch reaches 12 by performing the processing of 1,2,3,4, the subsequent operation command is not accepted for 6 minutes. The door can be reworked after 6 minutes.

3) Open door indicator (hereinafter referred to as ODi)

The state of the garage door 6 shown in FIG. 1 is shown, and it is comprised as the door indicator circuit 325 which flashes a lamp or a light emitting diode as a specific element. An example of the state of blinking is shown in FIG.

4) Double safety control.

If the upper limit switch 30 for setting the movement area or the lower limit switch 31 has failed, the door collides with the bottom surface if the door is descending, and if the door is rising, the upper stopper collides with the obstacle switch 52. ) Works. However, if the obstacle switch 52 is broken, the motor generates a lock torque (LOCK TORQUE) and continues to press the obstacle strongly until the thermal switch 192 is turned on. This condition is undesirable for safety reasons, and be prepared for the points listed below.

Since the moving distance of the door can be limited (for example, 9 pts 2.7 m), the moving time is also limited by itself. (If the door speed by 10m / min, travel time _T T = 2.7m / 10m / min ≒ 16 seconds) so that after the door operates a timer to set the timer TM ₈ (TM ₈₎ until the time to server OY If the upper limit, lower limit, and obstacle switch signals are not input, it is determined as abnormal and the obstacle detection process is performed.

If this function is present, for example, when a part of the drive system fails and the door does not operate (specifically, the belt slips and does not transmit rotational force, and the belt may be damaged by heat generated by this slip). Stopping the motor is effective in terms of safety improvement.

5) Disregard ignore control

Generally, friction is divided into static friction and motion friction, and the static friction side is large. In the case of garage doors, great power is required when the garage door is maneuvered. However, the door does not require much force while it is in operation. Therefore, in order to prevent the failure detection switch 52 from operating while the door is activated, the operation setting paper must be made large, and as a result, the failure detection force during the door movement also becomes a large value. As a result, in terms of operability and stability of the door, there is a contradiction with a small obstacle detection force required. As a countermeasure, in the embodiment of the present invention, the fault detection is ignored for a predetermined time (one second in the embodiment of the present invention) after starting. This evidence is based on the assumption that any door is fully mobile for one second after activation.

6) Upper and lower limit switch control

There can be no state of simultaneous input of the upper limit switch and the lower limit switch. As such a state, the following cases are considered. When the door is in the lower limit position and the lower limit limit switch 31 is turned on, the state in which the contact of the upper limit limit switch 30 is welded or a state in which part of the wiring is disconnected and in contact with the chassis is considered. do. When the door is in the upper limit position and the upper limit limit switch 30 is turned on, the state in which the contact point of the lower limit switch 31 is welded, or the state in which a part of the wiring is disconnected and is in contact with the chassis. Is considered.

In addition, there is a possibility that the disconnection phenomenon and contact welding occur in the upper and lower limit switches. As a countermeasure in such a case, when there is a simultaneous input, the door remains stopped even when an operation input signal is received.

7) Lamp lighting time control

In the additional circuit 316 shown in FIG. 8, a lamp lighting time of 2 minutes or 6 minutes can be set. In the embodiment of the present invention, the lamp is turned on at the same time as the door operation starts, the set timer TM ₁₂ is set after the door stops, and the lamp is turned off by the timeover of this timer.

8) Reception signal control

The signal transmitted from the radio control transmitter is demodulated in binarization circuit 330 and input to logic processing circuit 311. The format of this input signal is shown in FIG. This format method belongs to the NRZ (NONRETURN ZERO) method in the classification of the communication method. The method will be described below.

(1) The registration signal SYNC is composed of 16 bits, and the length of the registration signal SYNC is counted to confirm that the length is in a certain range, and then processed as a synchronization signal. First, the sampling period is determined by setting the synchronization signal SYNC to 1/16.

(2) Sampling starts by the falling of the synchronization signal SYNC. However, only the start bit (ST) sets the sampling length to 1/32. The start bit is always set to "0".

(3) After sampling checking 6 bits of data, check that the stop bit (SP) is "1". The next sampling is started by the fall of this stop bit SP. By doing this, the sampling error accumulation can be grouped in 8 bit units.

(4) After completion of checking of the frame stop bit FSP, " 1110 ", it is processed as an operation signal.

14 shows a main flow chart of the present invention. The process starts after the power is turned on. First, the RAM clear 360 is performed to reset the temporary memory circuit 349 to an initial state. Next, after processing the obstacle and detecting the lower limit, 361 is checked. The obstruction treatment certificate indicates state 310 of FIG. 6 and indicates that the state 309 is in process after the detection of the lower limit point. During this process, the door operation by a pushbutton switch or a multiplier reception is disabled.

When not in process, the ED (start count) value over flag 362 is checked. If the flag is " 1 ", the door operation by a pushbutton switch or transmission / reception is disabled.

If the flag is "0", the ON / OFF of the pushbutton switch (hereinafter referred to as WLSW) is checked. If the WLSW 363 is ON, the start input discontinuous timer set 366 is executed. OFF is carried out a check of the reception (hereinafter referred to as _X R) input 364, if the if the "1" level, and then transferred to a reception processing unit 365 of. Next, after the operation processing 367 and the timer processing 368, the cycle returns to the processing 361 after detecting the lower limit of the obstacle processing, and one cycle is formed.

The operation process 367 in this main flow chart will be described using FIG. 15 to FIG.

15 is a main flow chart of the operation processing. The ED value over flag 370 is checked. This ED value over flag is established when it detects that there is a high frequency light in a limited time as described in FIG. Doing.

When the flag is OFF, the flag 372 is checked during operation. When the flag is OFF during operation, it means stop, and the open door indicator circuit 325 (ODi) which is the door state display is turned off once. After this ODi extinguishing 373, the lower limit limit SW 374 is checked to see if the door stop state is at the lower limit limit switch position. If it is OFF, ODi light 375 is performed. If it is ON, ODi 325 remains off.

In this process, the stopped state 301 or state 303 shown in FIG. 12 is displayed. If the operation flag 372 is ON, it is checked whether or not the obstacle ignore period 376 is used. It corresponds to the time of the timer TM ₀ in the temporary storage circuit.

If the value of this timer TM ₀ is not checked and is not set, the fault input is ignored since it is within 1 second after the door starts. The reason for the obstacle ignore period 376 has been described above and thus will be omitted. If the obstacle is not ignored, it indicates that the door is moving normally, and the obstacle detection (377) is checked whether or not there is an obstacle. If a fault signal is input, the fault is flagged 378, and the obstruction process 379 is performed after the reverse mode OFF process.

When the obstacle ignore period 376 is reached, it is checked whether the obstacle flag 380 is ON or OFF. When the obstacle flag is ON, obstacle processing is performed, so the obstacle processing 379 is performed. If the stored object flag is OFF, it is checked whether the start input discontinuous timer 381 is set or reset. Corresponds to timer TM ₄ in the temporary storage circuit. The TM ₄ is set to 0.28 seconds when the door is in operation and 0.5 seconds when the door is in the stopped state.

This TM is that there are _4, and the reset means and the operation signal does not enter, it is necessary to continue the state of the door as it is. The flag 382 is checked during operation. When the flag is ON, the door is in operation. Therefore, the operation continuation process 383 is performed. When the flag is OFF, the operation continuation process 371 is performed. When the start input discontinuous timer 381 is set, the start input processing completion flag 384 is checked. That is, it identifies whether it is a completely new operation signal or once processing is completed. As long as this flag is ON

Next, the obstacle treatment 379 will be described with reference to FIG. In this process, the state 388, state 309, and state 310 shown in FIG. 3 are performed. However, in the state 309, it is a case of the failure detected during the fixed time descent.

First, the operation direction flag 390 is checked, and when this flag is ON, an out of lower limit stop process 391 is performed to signify an increase and stop.

If the flag is OFF, it means falling, so the lower limit SW 392 is checked. If the lower limit SW is ON, the state 309 is not required, and the lower limit stop SW 393 is performed.

When the lower limit SW 392 is OFF, the rising limit must be reversed. Next, when the obstacle 3 is stopped and the graph 394 is checked, the obstacle processing state 305 needs to be set. That is, the obstacle stopping flag ON (395), the obstacle stopping timer set 396 (this corresponds to the 10 degree timer TM ₆ ) 125 msec reference timer set 397 (this corresponds to the 10 degree timer TM ₃ ), stop The continuous processing 398 is performed.

When the flag during the obstacle stop is ON, the obstacle stop timer 399 is checked and the door is stopped until it is reset. This setting time is set to 0.5 second in the embodiment of the present invention.

When the stop timer 399 is reset, the obstacle flag, the obstacle stopping flag OFF 400, the reverse mode ON 401, the operating flag, and the operation direction flag ON to specify the state 306 of FIG. 402, motor falling reset, motor rising output 403, reverse timer set (1.875 seconds) 404 (this corresponds to timer TM ₈ in FIG. 10), 125m SEC reference timer set 405 ( This corresponds to timer TM of FIG. 10).

Next, the operation-to-stop processing 387 will be described with reference to FIG. The flag OFF 410, the rising and falling reset 411, the falling and falling reset 412, and the lower limit external stop processing 413 are performed as the stop processing.

Next, the stop-to-operation process 388 will be described with reference to FIG. 18. FIG.

First, it is checked whether the ED count timer 420 is set. This corresponds to timer TM ₁₀ of FIG. If it is set, it is in the I state shown in Fig. 11, and the ED counter update (+1) 421 is performed. If it is a reset, it means that it is in state II.

Next, the ED value overover 422 is checked. If the ED value is overovered, the ED value over flag ON 423, the ED value over timer set 424, and the 30SEC reference timer set 425 (this corresponds to timer TM ₉ in FIG. 10).

If the ED value is not overrun, ED count timer reset 426 is performed to initially clear the ED counter.

Next, the upper and lower limit SW ON (427) is checked. This is a state of the upper and lower limit SWs, and when either one is ON but at the same time, it is determined to be a failure and the door is not operated by continuing processing 428 during stop.

Next, the limit SW 429 is checked, and the down output is output when the upper limit SW is ON, the rising output is output when the lower limit SW is ON, and the mode is determined by the operation direction flag 430 when neither limit SW is ON. do. The input signal of the limit SW is given priority over the operation direction as the proof strength mode. The operation direction flag is stored in the temporary storage circuit 349 in FIG. 9, but all are cleared when the power is turned on, so the flag is OFF. In other words, the meaning of the flag is reversed only, flag OFF is rising, flag ON is falling.

In addition, when the operation direction flag 430 is ON, the process of raising a door rising reset, the door lowering output 433, and the operation direction flag OFF 434 is performed, and the next operation direction is raised. After the operation direction flag is determined, an operation start process 435 is performed.

Next, the operation start processing 435 will be described with reference to FIG.

In this process, all relevant flags and timers are set at the start of the operation, and a tight lighting is output. Then ODi flashing flag ON (440), door movement start flag ON (441), running flag ON (442), start input processing completion flag ON (443), lamp off timer reset (444) (this is the timer of FIG. TM ₁₂ ), ED clear timer reset 445 (this corresponds to timer TM ₁₁ in FIG. 10), ODi flashing timer set 446 (this corresponds to timer TM ₅ in FIG. 10), light on 448, the obstacle ignore timer set 449 (this corresponds to timer TM ₆ in FIG. 10), and the 12 msec reference timer set 450 (this corresponds to FIG. 10 timer TM ₃ ) are sequentially performed. Next, the continuous processing 383 during operation will be described with reference to FIGS. 20 and 21. FIG. In this process, the states 304 and 306 shown in FIG. 6 are mainly performed.

First, if the operation direction flag 451 is checked and ON, the lowering reset reset and the rising / lowering output 452 are always performed. After that, the upper limit limit SW check 453 is executed, and if ON, the outer limit stop processing 456 is performed. If the upper limit limit SW is OFF, the reverse mode 454 is checked, and if the mode is ON, the reverse timer is checked 455. The timer and the 10 degrees timer TM _6, if it is reset, so equivalent to 1 foot of rise of the sixth-degree state 306 and then is made as to the lower limit stop processing. And if it is a set, continue.

If the operation direction flag 451 is checked and OFF, the door rising reset and the door falling output 457 are always performed. After that, the lower limit SW 458 is checked, and if it is ON, the lower limit detection flag 459 is checked. If this flag is OFF, immediately after the lower limit input is input, the lower limit detection plug ON 460 is executed and the motor stop delay timer set 461 is executed. This corresponds to timer TM ₂ in FIG. 10. Next, the door movement time monitoring timer reset 462 is performed. This corresponds to timer TM ₈ of FIG.

If the lower limit detection flag 459 is ON, the motor stop delay timer is checked (463). If the lower limit detection flag 459 is turned on, the lower limit detection flag 459 is checked. 464).

In the embodiment of the present invention, timer TM ₂ is set to 225 msec.

Next, the lower limit stop processing, the lower limit stop processing, and the stop continuation processing will be described using FIG. 22 and FIG.

The start input discontinuous timer set 470, the obstacle processing, the flag for processing after the lower limit detection OFF 471, and the start input processing completion flag ON 472 are performed. The same applies to the case where it is stopped by the operation command input or when it is stopped by the upper and lower limit switch input.

Next, the ED count timer set 473 is executed. This corresponds to timer TM ₁₀ of FIG. The write start time is checked by the write start time 474 by checking the 2-minute or 6-minute select signal set by the additional circuit 316 of FIG. 8, and the light off timer 2 minutes set 475 and the light off timer 6 minutes set are set. One of 476 is selected. Next, the ODi blink timer reset 477, the ODi blink flag OFF 478, and the ED clear timer set 479 are performed. This corresponds to Timer TM ₁₁ in FIG. 10 and is set to 6 minutes in the embodiment of the present invention.

Next, a 30 sec reference timer set 48 is performed.

During the next processing, the flag OFF 481 during operation, the door lowering reset, the door rising reset 48, and the door movement time monitoring timer reset 483 are executed. Next, the timer processing 368 in the main flowchart of FIG. 14 will be described using FIGS. 24 to 27. FIG.

This flowchart processing unit counts its own step number and replaces it with a timer, and corresponds to FIG. 10 with respect to an individual timer counter. Here, a symbol is added to clarify only the correspondence on the map. A 15.625 msec timer counter update 490 is performed, and the time over of this timer TM ₁ is checked in the time over 491. Here, one cycle of the main flow chart is 97 steps, and if it is counted as 4 bits, the overflow occurs by time overruning at the 16th time. One step is 10μsec, 16 × 97 steps

The output of the time over 491 is every 15.625 msec. Therefore, the motor stop delay timer counter update 492 (timer TM ₂ ) and the timer counter update 493 based on 125 m sec (timer TM ₃ and timer TM ₃ are + Since it counts by two), 125 m sec is guaranteed in the over flow in the time over 494.

The contents of the timer correction 495 at the time of reception establishment, which is the next process, will be described later. However, in this process, the discontinuous timer is not updated when the timer is corrected. When the reception is satisfied, the start input discontinuous timer counter 496 is checked when the timer is not corrected. When the counter value is not 0, the timer counter update 497 (timer TM ₄ is executed and checked in the time over 498. If there is a time over, the start input processing completion flag is turned off (499). ODi flashing counter Check (500).

When the counter value is not zero, the timer counter update 501 (timer TM ₅ ) is performed and checked in the time over 502. If there is a time overover, ODi flashing processing (503) is performed.

That is, the ODi is flickered by the ODi flashing flag to perform the state 300 and state 302 of FIG.

Next, the obstacle ignore timer counter is checked (504). When it is not 0, the timer counter update 505 (timer TM ₆ ) is performed and checked in the time over 506. If there is a time overover, the movement time monitoring timer process 507 is executed. The processing here sets the movement time monitoring timer by turning the door movement start flag OFF. Next, the 2 sec reference timer counter update 508 (timer 0TM ₇ ) is performed in the processing so far, and the time over 509 checks. If there is a time over, 2sec elapses.

Next, the movement time monitoring timer counter 510 is checked. When it is not 0, the timer counter update 511 (timer TM ₈ ) is performed and checked in the time over 512. If there is a time overover, the shift time over processing is performed. In this case, the obstacle flag is ON and the reverse mode is OFF. That is, the time over occurs after 25 seconds when there is no input from the upper limit switch, the lower limit switch and the fault limit switch after the door is started. The output is made to be equivalent to the fault detection process.

Next, a 30 sec reference timer counter update 514 (timer TM ₉ ) is performed and checked by the time over 515. If there is a time over, 30 seconds elapse. Next, a 30sec reference timer set 516 is performed. This is because the 30 sec reference timer TM ₉ is based on the timer TM ₇ and needs to be overflowed at 15 counts. Here, "1" is set in the timer TM ₉ counter.

Next, the ED count timer counter 517 is checked. If not 0, the counter update 518 (timer TM ₁₀ ) is performed. Next, the ED clear timer counter update 519 (timer TM ₁₁ ) is performed and checked by the time over 520. If there is a time overover, ED clear processing (521) is performed. The processing here corresponds to state III in FIG. 11 with the ED counter clear and the ED value over flag OFF.

Next, the write off timer counter update 522 (timer TM ₁₂ ) is performed and checked by the time over 523.

If there is a time overover, the light extinction process 524 is performed.

Next, before describing the main flow chart reception process 365 in FIG. 14, the transmission / reception scheme will be described again.

A circuit example of the transmitter 331 will be described using FIG. 28. FIG. The clock oscillation circuit is formed by the inverters 530, 531, resistors R ₁ , R ₂ , and C ₁ , and is input to the counter 543 via the inverter 532. The lower 3 bits of the counter 543 are input to the decoders 545, 546, and 547, and the upper 3 bits are input to the decoder 544. Here, the outputs obtained by decoding the upper three bits (Q ₁ to Q ₅ ) correspond to eight times the lower (Q _A ) bits of the counter 543, respectively. Therefore, 40 bits are formed by the outputs Q ₁ -Q _{5 of the} decore header 544. Here, (Q ₁ ) and (Q ₂ ) outputs are input to the three-input NAND 552, which is equivalent to 16 bits of the synchronization signal.

Next, in Q ₃ , the decoder 545 is selected by the inverter 533 to decode the lower 3 bits of the counter 543, and to output the decoder 545 to an open-drain type inverter 537. It outputs to six inverters, and this output sequentially scans the bit switch 548 (6 contacts) which is a bit setting part, and inputs ON-OFF information to the three input NAND 552 via the inverter 536.

Similarly, the decoder 544 (Q ₄ ) output is selected through the inverter 534, and the decoder 546 is selected to open the inverter 539 (for six inverters) and the bit switch 549 (6) of the open drain type. (Q ₅ ) output of the decoder 544 through the inverter 535, and the decoder 547 is selected so that the open-drain inverter 541 (for the three inverters) and the bit switch ( 550) (three contacts) are sequentially scanned. Here, the open drain type inverters 538 and 540 are one, corresponding to the stop bit SP, and the open drain type inverter 542 (for three inverters).

By performing the above operation, when the RF oscillator 551 which is the UHF generator is ON-OFF controlled by the three-input NAND 552, the radio wave output of the transmitter 331 is as shown in FIG.

The information transmitted in this manner is input to the logic processing circuit 311 under the reception by the receiving circuit 330 which is a super reproducing circuit. The bit setting circuit 321 is disposed in the logic processing circuit 311. An embodiment of this bit setting circuit 321 is shown in FIG. This circuit consists of bit switches 560, 561, 562 and diodes Di ₁ -Di ₁₀ and the logic processing circuit outputs R ₀ -R ₃ , R ₁₀ -R _l3 , D ₁ ) And (D ₂ ) the 10-bit output is sequentially controlled so that only 1 bit is always "1" and the other 9 bits are "0" (open drain but high impedance state), so the bit switch is turned on and off. Information is taken from the input ports I ₁ and I ₂ .

30 is a setting pattern when taking in the information of the bit switch. Frame No. Is corresponding to the data, and the data (D ₁ -D ₅ ) are the frame nos. 0, the data (D-─ D ₁₀ ) is the frame number. 1, data (D ₁₁ -D ₁₅ ) are frame Nos. 2, frame stop bit is frame no. 3. In addition, as a bit counter, it is excellent from start bit ST to stop bit SP.

In addition, the output pattern and input port at the time of taking in the information of a bit switch become like a figure.

Next, the reception process 365 will be described with reference to Figs. 31-37.

The obstacle limit SW check 570 checks the obstacle when the door is in operation and the limit SW in the operation direction. When not in operation, the number of processing steps is matched. Details are shown in FIG. When there is an obstacle in this process, or when the limit SW in the operation direction is turned on, a status flag (formerly located in the status display register of FIG. 9) is set. The check of the obstacle limit SW input 571 which is the next process may be performed only by checking the status flag. Jumps to GFC ₁ when status flag is ON. When the status flag is OFF, the synchronization signal counter update 572 is executed. As the synchronization signal counter, 8 bits are prepared in the temporary storage circuit 349 shown in FIG. 9 as shown in FIG. Next, check whether the value of this counter has been continued for a certain time or more. That is, the maximum value of the waveform input as the original synchronization signal is set. If the counter value is larger than that, it is determined to be abnormal and jumps to GFC ₁ . If the result of the synchronization signal counter 1 upper limit 573 is N, the reception data = 0 (574) is performed, and it is checked whether the data is 0, that is, the synchronization signal is finished. If the data is not zero, the process returns to the obstacle limit SW check 570.

The loop of L ₁ shown in the figure is repeated until the received data becomes zero. When the data reaches 0 in the received data = 0 (574), the synchronization signal counter 2 lower limit value 575 is checked. That is, the minimum value of the waveform input as the original synchronization signal is set, and if the count value is smaller than that, it is determined to be abnormal and jumps to GFC ₁ .

用)출력패턴초기치세트(576), 프레임 No, 초기치 세트(577)를 제30도와 같이 행한다.If the result is "Y" at the synchronization signal counter 2 lower limit 575, Dip SW is read (讀

The output pattern initial value set 576, frame No, and initial value set 577 are performed as shown in FIG.

Next, FIG. 32 will be described.

The sampling timing counter initial value set 578 is performed. This coincides with the next bit counter initial value set 579, and shows the processing time length required for FIG. 31, the synchronization signal counter 2, the lower limit value 575, the output pattern initial value set for the Dip SW Germany, the frame number and the initial value set. It is meant to correct as an error from the state to the start of sampling.

The obstacle limit SW check 580 checks the limit SW in the obstacle operation direction when the door is in operation. When not in operation, the number of processing steps is matched. Details are shown in FIG. When there is an obstacle in this process, or when the limit SW in the operation direction is turned on, a status flag (this is in the status display register in FIG. 9) is set.

The check of the obstacle limit SW input 581 which is the next process may be performed only by checking the status flag. Jump to GFC ₁ when status flag is ON.

Next, the sampling of the start bit 582 is checked. As described above, 1/32 is the start bit as the sampling period, and 1/16 otherwise. Therefore, the sampling counter update 583 updates by +2 to 1/32, and the sampling counter 584 updates by +1. Next, the sampling time afternoon 585 is checked, and if the result is N, the process returns to the obstacle limit SW check 580. The loop of L ₂ shown in the figure is repeated until the sampling time over. The number of processing steps of the loop of FIG. 31 and the number of processing steps of the L ₂ loop of FIG. 32 are the same. When the sampling time over 585 becomes "Y", sampling error correction 586 is performed.

The number of processing steps in the L ₁ loop described above is 32. Therefore, 32 processing steps / loop × 1/16 = 2 processing steps / loops are obtained, and the error is corrected by counting by the value of the synchronous counter lower digit as one count two processing steps.

Next, FIG. 33 is explained.

Processing 578 is performed to receive the received data into the carrier. The carrier referred to here is the status display register 346 shown in FIG. Next to frame No. 3 or frame stop bit FSP. Check at 3 (579). If Y, jump to GFC ₈ .

Frame No. If not 3, the following process is corrected and the start bit 580 is checked. The start bit-in is determined by looking at the bit count value. If the bit counter value is 0, jump to GFC ₄ .

If the bit count value is not 0, the transfer proceeds to the next process and the stop bit 581 is checked. Whether it is a stop bit or not is determined by looking at the bit counter. If the bit counter value is 14, jump to GFC ₅ . If it is not a stop bit, the reset 582 of the DiP SW outputs D ₁ and D ₂ and the output pattern log 583 for Dip SW read processing are processed. Then, frame no. 1 (584) is checked. Frame No. If not 1, Dip SW output (0-3) output (585) is processed.

Next, the output pattern 586 is checked, and if it is 0, the DiP SW output D ₁ is output 587. If the output pattern is not 0, the DiP SW output D ₁ is reset 588. . That is, as can be seen from the output pattern, (R ₀ -R ₂ ) is a 4-bit latch and D ₁ is a 1-bit latch. For this reason, the output pattern setting method is used. This is flame no. Dip SW output (4-7) output (589), output pattern (590) check, Dip SW output (D ₂ ) output (591) when reset, reset 592 of Dip SW output (D ₂ ) The same applies to the same.

Next, FIG. 34 will be described.

In the check of the stop bit 581 in FIG. 33, it is determined that the stop bit is input, and then the stop bit normal 593 checks that the signal is a stop bit, that is, "1". If it is "0" input, it is not a stop bit, so it is not a normal reception state, and subsequent sampling is not performed.

Jump to GFC ₁

If the stop bit normal 593 is checked and it is a normal stop bit, the following processing is performed. After checking the received data 594, receiving the obstacle limit SW check 595 and the obstacle limit SW input check 596, confirming that the received data is "0" in the received data 594 on the way out, and exiting from this loop. Sampling counter initial value set 598 is performed. Then jump to GFC ₁₀ . From this point, the level check is performed on the received data 594 and the signal falls, and from that point of sampling to start a new sampling.

When the output pattern is not " 0 " due to the check of the output pattern = 0 (607), the output pattern is updated (doubled) 610 while still being processed in the same frame.

As the next processing, the sampling counter initial value set 610 is executed, and the bit counter update (+2) 611 is performed. Jump to the GFC ₉ position shown in FIG.

When jumping to CFC ₈ in FIG. 35, the data is matched and requires 80 msec as the average processing time in the reception process and the flow chart (since 1 bit is 2 msec and 1 frame is 40 bits). Therefore, in order to perform the reception process 365 in FIG. 14, the timer process 368 is greatly affected. As a countermeasure against this, as an embodiment of the present invention, the 15.625m sec timer in the timer processing 368 is called five times by the timer counter correction 612. An approximation process is performed to correct the main timer. Next

In FIG. 33, the start bit 580 checks in the start bit normal 597 that the signal is a start bit, i.e., " 0 "

If the input is "1", it is not a start bit, so it is not a normal reception state and subsequent sampling is not performed. Jump to GFC ₁

If the start bit normal 597 is checked and the normal start bit is set, a sampling counter initial value set 598, which is the next process, is performed.

35 is a 33th frame No. 3 (579) check frame No. Processing in the case where 3 is determined.

The bit counter checks whether or not the stop bit is in the stop bit 599. When the bit counter value is (8), (10), or (12) values, the check data = 1 (600) is checked. When this bit counter value is received, the received data must be "1", and the jump to GFC ₇ represents a normal case. If the received data is "0", the reception status is abnormal and jumps to GFC ₁ .

If the bit counter is 14 in the stop bit 599 check, the received data = 0 (601) is checked. When this bit counter value is received, the received data must be "0" and jump to GFC ₈ indicates normal case. If the received data is "1", the reception status is abnormal and jumps to GFC ₁ .

36 is a continuation in FIG. Frame No. The input ports of Dip SW set by the check of = 2 (602) are distinguished. As shown in FIG. 30, the frame No. If = 2, the input port is I ₂ and corresponds to Dip SW input (11-15). Here, the Dip SW inputs 11-15 and 605 are checked to check if the received data = 1 (604) if " 1 ". If " 0 ", the received data = 0 (606) is checked. If the result of the check matches, the output pattern = 0 (607) is checked. If there is a mismatch, the reception processing counter zero (0) is cleared and the reception processing i / 0 port reset 614 is performed.

In the above case, if the frame No. When not = 2, input port is I ₁ and corresponds to Dip SW input (1 ~ 10). Therefore, check the Dip SW input (1-10 (603) and check the received data = 1 (604) if it is "1", and check the received data = 0 (606) if it is "0". If there is, the output pattern = 0 (607) is checked, and if there is a mismatch, the reception processing counter zero (0) is cleared and the reception processing i / 0 forest set 614 is performed.

As the next process, output pad = 0 (607) is checked. If the output pattern is " 0 ", it means that data 5 bit check has been completed, and it is necessary to set a new data acquisition pattern in the next frame.

For this purpose, an output pattern initial value set 608 is performed and " 1 " is set as an output pattern. Frame No. Update (+1) 609 is performed. Sampling count initial value set 610 is performed as a next process, and bit counter update (+2) 611 is performed.

Jump to the position of GFC ₉ shown in FIG.

37 shows the contents of the obstacle limit SW check process. First, during operation, the flag 615 is checked, and when it is ON, that is, during operation, the obstacle SW 616 is checked. If the obstacle SW is ON, the status set 620 is performed. The obstacle SW OFF condition checks 617 the limit SW of the operation direction. If it is ON, the status set 620 is executed.

If OFF, status reset 618 is performed. If the in-operation flag 615 is OFF, i.e., in stop, the timer will fluctuate during stop and operation unless it matches the number of processing steps required in operation. Therefore, step number matching 619 is performed.

The door opening and closing device as described above has been previously filed in the United States (corresponding to Japanese applications: Japanese Patent Application Offices 54-21066, 54-21067, 54-21068, inventors: Shigeru matsuoka, Toshio Tsubaki, Takehi Tokunaga, Seiji Yonekura, Kenji Nakamura, Mitsuo Suzuki Described in the specification and drawings.

Next, detection and processing of abnormal conditions in the garage will be described. 1 shows an example in which a fire accident detection device and an anti-theft device are provided as abnormal state detection means.

As one example of a fire accident detection device, a fire accident detection device 648, which is generally known based on a smoke detection-ionization principle, is asleep and installed on the ceiling. In addition, a magnet-lead switch system, which is generally used as an anti-theft device, is used, and the presence or absence of an intruder is detected by capturing the state change of this combination. That is, if there is an intruder, the magnets 651 and 649 and the lead switches 652 and 650 are arranged at positions where the window 653 or the auxiliary door 660 is in a closed state. In addition, the output signal of the fire accident detection device 648 is a contact point, and the wires 657, 658, and 669 between each detection device and a control device for logically judging the output signal from each detection device. ) Is connected.

The control device 13 is further provided with a control switch 654 for instructing whether or not the abnormal state detection device is operated. As an alarm, there are an alarm 655 provided in the garage and an alarm 656 provided on the housing 661, each of which is connected to the control device 13 by wires 659-a and 659-b. . Each of the alarms 655 and 656 is driven by the alarm circuit 326 shown in FIG.

Next, before describing the operation processing example of the present system, the operation conditions and processing conditions in the abnormal state will be clarified.

(1) The intruder's alarm activates any alarm in the garage or dwelling at the same time.

(2) In the garage, the alarm 655 and the lamp 38 are operated when an intruder is detected.

(3) The intruder detection process is not performed when the door 6 is at rest other than the lower limit.

(4) When the door 6 is moving and after the door 6 stops, the intruder detection processing is not performed for a certain time.

(5) When a fire accident is detected, all warning means in the garage or dwelling shall be activated at the same time.

(6) When a fire accident is detected, the door 6 is raised unless the door 6 is stopped at the upper limit position. This is to aid in extinguishing and to facilitate the removal of cargo from the garage.

(7) The set and reset of this system is performed by the control switch 654 provided in the control apparatus 13. As shown in FIG.

(8) The alarm operates not only the alarm function of the abnormal state but also the door 6 while it is descending, so as to warn people near the door 6. However, the alarm sound is interrupted (flicker) to distinguish it from the abnormal alarm. This is only the in-garage alarm 655.

(9) In addition to the alarm function only in the event of an abnormal condition, the alarm device operates while the door 6 is being raised to alert that the door 6 has been operated. However, the alarm sound shall be short (flicker) to distinguish it from the abnormal alarm. This is done only with the residential alarm 656.

38 shows an example of the alarm 656 installed in the house. The light emitting diodes 665 and 666 are for displaying the state of the door 6, and are part of the door indicator circuit 325 shown in FIG. 8, and the door 6 flashes during operation and the door 6 lower limit Lights out when the point stops, and when the door 6 stops other than the lower limit point has already been explained. The buzzer 667 is a volume switching switch 668 to control the operation volume. This volume switching switch 668 is noisy if the volume is loud even when the normal door 6 is operated (only flicker information during the rising of the door 6). When the volume change switch 668 is set to a large side when going out, the buzzer 667 generates a large flicker sound just by raising water 6 when returning home and attempting to put it in the car. And if an intruder is in a dwelling rather than a garage, a threat alert can be expected of its own effect.

The processing flow performed under the above system arrangement conditions will be described with reference to FIGS. 39 to 43. This process is inserted in the above-described operation flowchart, and has been described in contrast with the relation to the already described drawings in order to clarify the front-rear relationship.

FIG. 39 shows the insertion position of the abnormality detection processing 670 with the insertion into the main flow chart shown in FIG. 40 shows the processing contents for the fire accident input of the abnormality detection processing 670. The check switch 681 is checked. If it is ON, a check (682) is performed to see if there is a fire accident (smoke detection: 煙 檢 知). As a result, jump to GFC ₁ unless a fire accident occurs. When the occurrence of the fire accident is confirmed, the lamp 38 is turned on 683, the buzzer G, the H ON 684, and the S1 flag set 685 are performed. Here, the buzzer G means the buzzer of the garage alarm 655, and the buzzer H means the buzzer 667 of the alarm 656 in the house.

The following describes the buzzer G and H.

The S ₁ flag is a flag that means fire accident detection processing. Next, the state of the door 6 is checked. That is the check 686 of the upper limit limit switch. If there is no door 6 at the upper limit, the door 6 is forcibly raised. That is, the door lowering reset, the door rising output 687, the operation direction flag ON 688, and the operation start process 689 are performed. As a result, any door that is descending will immediately reverse and rise. Of course, if there is a door in the upper position, it will remain there.

If the check of the control switch of the above (681) the control switch is OFF performs a check 690 of the flag S ₁ in the following. If OFF, jump to GFC1. If it is ON, a fire accident is detected once and then the control switch is turned OFF, and it is judged that there is a system release input, and the buzzer G, H (691), S ₁ flag reset (692), and the light off timer (2 minutes) set 693 Is done.

The lamp 38 is turned off 2 minutes after the control switch 654 is turned off by performing the light off timer 2 minutes set 693 here.

41 shows processing contents for the anti-theft input of the abnormality detection processing 670. As shown in FIG. A check 94 of the flag in operation is performed to determine whether the door is stopped or in operation. If this flag is OFF, i.e., stopped, the control switch 669 is checked next. If the control switch is ON, the lower limit limit switch is checked (696). As a result, if the lower limit switch is OFF, that is, the door stops at a position other than the lower limit position, the main flow jumps to the return flow. When the lower limit limit switch is turned on, the S ₂ flag is checked 697. If this S ₂ flag is OFF, this means that there is no condition for the anti-theft protection to operate. In other words, the door 6 does not pass for a certain period of time after stopping. Thus, a check 698 is performed to see if the light 48 is extinguished. If the light 38 is extinguished, the S ₂ flag set 699 is executed. In other words, the anti-theft function starts to operate when the lamp 38 is turned off. In check 697 of the S2 flag, this flag is turned ON, i.e., as described above, a check is made after the stop for a predetermined time to check whether an anti-theft input is present. This is windows 653, bo

Next, an example in which alarms 655 and 656 are used to increase the safety when operating the garage door will be described using FIG. 42 and FIG. 43. Here, the alarm displays the operation of the door 6. This processing is inserted into the ODi flashing processing flow described in FIG. The ODi flashing counter is checked 500, and when the counter value is not 0, a timer counter update (timer TM5) 501 is performed and checked in the time over 502. If there is an ODi timeover, ODi flashing is performed. In this case, the ODi blinking processing is performed by checking the ODi blinking flag (713). If it is ON, the ODi light is turned on (714), the ODi blinking flag is turned off (715). 717) and ODi blinking timer set 718). That is, the flashing is repeated every certain time. Is then subjected to a check 179 of the flag S ₁ is ON and OFF by jumping GFB3 jumps to GFB4. When it is ON, a fire accident is detected, indicating that it is being processed and that the door is rising.

In the check 500 of the ODi blinking timer counter, if 0, it indicates that the door is stopped. The check is performed by checking the S ₁ flag (710) and the S ₂ flag (711), and when both flags are OFF, the buzzer G, F OFF (712) is performed. In GFB4, the ODi blinking flag is checked 720, and if this flag is ON, the operation direction flag is checked 721. If ON, a buzzer H ON 722 for turning on the residential buzzer and a buzzer G ON 723 for turning on the in-garage buzzer are performed. That is, buzzer G and buzzer H are selected and alarmed according to the state of the door 6. If the check 720 of the ODi flashing flag is OFF, the buzzer H OFF 725 and the buzzer G OFF 726 are similarly performed by the check 724 of the operation direction flag.

By the above process, the buzzer G can alert the flicker (clamp) while the door is lowering, and the buzzer H (clinker) can alert the door while the door is rising. The allocation of the S ₂ flag of the S ₁ flag is set to 0 area in FIG.

Next, the alarm described using FIG. 38 will be supplemented with FIG. 44. FIG.

44 (a) shows a volume switching method in which a resistor 730 is connected to the buzzer 667 in series. When the resistance is short-circuited by the volume switching switch, the volume range is not shorted. Is divided by the resistance to be the volume level. 44 (b) shows a completely different buzzer 731 for switching by the volume switching switch.

In order to enhance the effect of the present invention, it is also a control to display the status by not only the volume but also the sound quality or tone. Although a plurality of buzzers may be manually selected, it is easy to automatically control the selection process by the control device 13. And since such a process can be achieved very simply, description is abbreviate | omitted here.

And in this embodiment, the alarm in the garage is installed on the garage wall surface, but as the installation position may be installed in the main body (1) built-in or on the side of the main body (1) and do not need to specifically limit. Next, in the embodiment of the present invention, the input from each abnormal state detection device is connected by an electric wire. However, in order to further improve the function of the present invention, the input signal transmission form may be taken without wires. As an example, the case where radio waves are used using FIG. 45 will be described.

The magnet 651 is installed in the frame of the window 653, and the transmitter 735 including the lead switch 652 is mounted on the wall. When the window 653 is opened, the lead switch 652 is turned off, and the transistor 737 is turned on. As a result, the transistor 738 is also turned on, and the voltage from the battery 736 is applied to the RF oscillator 739 which is the UHF oscillator. As a result, the RF oscillator 739 starts oscillation. In the control apparatus 13, it receives by the receiving circuit 740 which is a super regeneration circuit, and integrates the signal in the integrating circuit 741. The comparator 742 compares and outputs the propagation of a certain period of time. This signal may be input to the same circuit as when the wire is connected.

However, a multi-channel method is required which is different from the radio waves for door operation and separates the UHF oscillation frequency.

In addition, as used for door operation, by adopting a method of distinguishing an abnormal state from a code by adopting a bit code method, it is possible to easily determine from the controller side what kind of abnormality has occurred.

Although two devices, a fire accident detection device and an anti-theft device, have been described as an embodiment, the effect of the present invention can be sufficiently achieved even by installing a gas sensor such as carbon monoxide, which is a dangerous gas to the human body. For example, when there is an output from the gas sensor, there is a person in the garage, and the door is automatically opened to introduce fresh air when the person is unhappy. The alarm is opened while the alarm means is activated. It is also a warning alert that alerts nearby people and urges them to improve the condition as soon as possible. As an actual process, it is good to process similarly to the fire accident detection process shown to FIG. 39-41.

Although it was explained that the door is opened as a treatment after the abnormal fire detection, but in the sense of preventing the fire from moving to the next door, it may be judged that closing the door is effective.

Such processing is performed by, for example, checking the upper limit limit switch 686 shown in FIG. 40 as the check limit 686 'of the lower limit switch, the following statement falling output, sentence rising reset 687', and operation direction flag. Turning to OFF 688 ', processing flow is achieved.

In the present embodiment, the anti-theft function is to act when the door 6 is located at the lower limit. However, in consideration of operating the present invention more effectively, it is necessary to add a new sensor. In other words, if the door is slightly open and stopped from the floor, at least the gap should be detected by not being able to enter or exit. In this case, it is natural that there is an interval for the cat or the dog to enter and exit, and even in such a case, the present invention works effectively. Actually magnets and lead switches

In the present embodiment, the anti-theft function is activated at the same time that the lamp 38 is turned off, and the ON and OFF of the function are indicated by the lamp. However, in this process, the 2-minute timer may be too long, and a dedicated timer process may be performed. This timer processing may be started after the door stops, or may be started after the control switch is turned on. Since the processing flowchart can be easily virtualized, the description here is omitted.

Application examples of the present invention may be as follows. In the above embodiment, time management is time-divided for each constant processing step by using a part of the temporary storage circuit as the start means. However, in this way it is cheaper to configure, but the time precision is not so good. As a means of improving this time precision, there is a method of separately using a means of time-time again. Specifically, there are a circuit and a time-measuring circuit which allow the program memory circuit to filter out light and set a specific value. Alternatively, a circuit capable of generating timing pulses at regular intervals may be connected to the input / output circuit, and the input of the timing pulses may be prioritized over the program processing being executed. In this manner, the start processing can be performed by counting the number of timing pulses or by using the input signal at a specific timing length. Such a method is generally referred to as an interruption treatment. In the above embodiment, as a basic state transition example of the door opening and closing device, the cycle operation of rising-stopping-falling-stopping is performed.

Whenever the operation input signal is received, the operation-stop is repeated. When the door open / close device reaches the upper limit position or the lower limit position, the door open / close device is stopped. Upon receiving the next operation input signal, the direction of motion is reversed and the door is moved according to the direction of motion indication.

Repetition of Rise-Stop Repetition of Rise-Stop

In the above embodiment, the operation input signal is not configured to directly indicate the direction of movement of the door. However, when the switch is input by providing a switch for raising and lowering in the additional circuit, the switch is input. Moving the door in the direction indicated by < RTI ID = 0.0 > is just < / RTI > added to the processing program and can be easily implemented.

Also in the embodiment, there is a means for directly instructing the direction of movement of the door. In the circuit where the upper limit limit switch and the lower limit switch are input, it is good to add a switch in parallel with this switch, and as a processing program, it is easy to output the falling command when the upper limit switch is ON and the rising command when the lower limit switch is ON. I can tell.

In the above embodiment, as the processing after the detection of an obstacle, an example of a state transition in which ascending during a stop, while descending during a descending time stops after a fixed time, rises for a fixed time.

The present invention is the processing after the detection of the obstacle, the control is in accordance with the state of the door in operation, the process of reversing the door or removing the stop for a certain time or processing to rise to the upper limit position without rising for a certain time It is possible to freely expand the state transition processing control.

As the processing after the failure detection, the processing may be performed without receiving a new operation input signal and the new operation input signal may be received after the processing is completed. As the processing after the failure detection, a new operation input may be accepted and processed regardless of this process.

In the above embodiment, when the operation time management of the door opening and closing device is performed and the various state detection signals of the door opening and closing device are not input within the operation time, it is determined that the process is abnormal. According to the present invention, by performing the operation time management, it is only necessary to make the state different from the state of the door in operation, and the following processing can be considered.

(1) The door opening and closing device is stopped.

(2) Reverse the door opener.

(3) The door opening and closing device is operated for a predetermined time if the door opening and closing device is in a closed or closed operation.

(4) The door opening and closing device is operated when the door is opened or stopped and closed.

When the direction of operation of the door is reversed in the second, third, and fourth terms, it may be stopped for a predetermined time. In the process, the new operation input signal may not be accepted until the process is completed. It is also possible to accept a new operation input signal during the processing. In the above embodiment, processing is not particularly preferentially performed as the detection input from the state detection device in the execution processing procedure. However, it is also possible to give priority to the state detection apparatus so as to process it in preference to an executing program generally called intervention intervention control. It goes without saying that system performance is always the door opening and closing device by adding safety devices or performing priority processing as described above for a specific signal input.

According to one embodiment of the present invention, the following effects are obtained.

(1) When an operation command is given to the garage door, the anti-theft function is automatically removed and it is easy to enter the garage.

(2) The anti-theft function does not work when the garage door is stopped outside the lower limit position, so opening and closing of the auxiliary door and opening and closing of the window is convenient when working in the garage.

(3) According to 1 and 2, it is good to keep the control switch ON all the time, and there is no accident even if you forget to set it.

(4) In case of fire, the door is automatically opened, so it is easy to take out and extinguish cargo.

(5) When there is an anti-theft input signal, at the same time the buzzer automatically illuminates the garage, so the infringement is very high for intruders.

Next, one embodiment of the control device will be described with reference to FIG. Denoted at 12 is a pushbutton switch for a door open / close operation command, 201 is a relay contact output for a door open / close operation command at a wireless receiver, 30 is an upper limit limit switch, 31 is a lower limit limit switch, and 52 is an obstacle detection limit switch. 205 is a reset circuit for generating a power-up series reset signal, 206, 207 is a monostable multivibrator 208 is a JK main-type flip-flop, and 209 is a D-type flip-flop using a NE555 (signature manufactured by NE555). 212 is the red circuit, 213 is the differential circuit, 214 ~ 222 is NOT device, 223 is 2 input OR device, 224 ~ 228 is 2 input AND device, 229 and 230 is 4 input NOR device, 231 is 2 input NOR device, 232 Is a three-input AND element, 233 is a transformer for control power, 234 is a diode stack, 235 is an IC regulator for control power, 236-238 is a relay driving transistor, 239-241 is a relay coil, and 242-244 is the relay contact point. 245 mowers for driving 38 is a lamp. The circuit operation will be described below with the time charts of FIGS. 47 and 48. FIG.

When power is supplied to the circuit, the control power supply VDD is supplied from the transformer 233 via the diode stack 234 and the IC regulator 235. The power supply reset circuit then integrates this rise of VDD and outputs a reset pulse by the NOT element 215. This reset pulse resets the JK master / slave flip-flop 208 via the NOT element 216 and through the four input NOR elements 229 and 230, respectively, the D-type flip-flops 210 and 211. ). If the signal A is outputted by the NOT element 214 by the relay contact output 201 of the push button switch 12 or the wireless receiving device which is a door open / close operation command, the monostable multivibrator 206 is raised by the rise of the signal A. ) Outputs a signal B having a pulse width T ₁ . The signal C is output via the two-input OR element 223 and the input AND element 224. The signal C is input as the clock of the JK main / vertical flip-flop 208, and the output of the two-input AND element 226 is set to the clock of the flip-flop 210 in the high (HiGH) period of the signal before the output signal E is inverted. And the flip-flop 210 is set so that the signal F is output. This is a door rising command, and the relay coil 240 for door rising is excited by the transistor 237, the relay contact 242 is turned on, and the motor 16 rotates forward. In this way, the motor is started, but at the same time, the signal B is input as a trigger signal to the timer circuit 209 via the NOT element 221.

This is for the purpose of turning on the lamp 38 which illuminates the inside of a garage for a predetermined time after an operation command with the motor starting, and the output of the timer circuit 209 excites the relay coil 239 by the transistor 236. The relay contact 244 is turned on. In this manner, the lamp 246 can be turned on for a predetermined time. Next, when the upper limit limit switch 30 is turned on during the rising command output, the flip-flop 210 is reset through the NOT element 217 and the four-input NOT element 229, and the transistor 237 is turned off. Coil 240 is elementally reeled

This signal D is input as a reset signal of the flip-flop 210 via the four-input NOR element 229.

In this way, the motor 16 is stopped similarly to the above. When the operation command is input in the same manner as described above, since the JK main / vertical flip-flop 208 is set, the output of the two-input AND element 226 is prohibited, and the signal B is output from the two-input AND element 225 so that the flip-flop ( 211) is set and the signal G is output.

As a result, the transistor 238 is turned on, the relay coil 241 for lowering the door is excited, the relay contact 242 is turned on, the motor 16 is reversed, and the door is lowered. When the lower limit switch 31 is turned on during the lowering operation, a signal H is output from the NOT element 219, and a time delay T ₂ is provided by the integrating circuit 212 through the 4-input NOR element 230 to flip the flip flop 211. Is input as a reset signal. As a result, the motor stops as in the case of the upper limit limit ON at the time of ascent.

Next, the circuit operation | movement when the obstacle detection limit switch 52 operated is demonstrated. If the obstacle detection limit switch 52 is operated during the ascending operation, i.e., when the JK master / species flip-flop 208 is set, and the frill flop 210 is set, and the flip-flop 211 is reset, this limit Since the switch 52 uses the contact B, the switch 52 is turned off, and a high signal is output from the two-input NOR element 231 via the NOT element 220 to trigger the monostable multivibrator 207. The Q output pulse of this multivibrator 207 resets the flip-flop 210 via the 4-input NOR element 229. At this time, since the JK main / vertical flip-flop 208 is set in the four-input AND element 232, the output of this AND element is prohibited. If the obstacle detection limit 52 operates as described above when the JK main / long flip-flop 208 is reset, the flip-flop 210 is reset, and the flip-flop 211 is set during the lowering operation. As described above, the signal J is output from the NOT element 220, and the signal K having a pulse width T3 is output from the monocular multivibrator 207 via the two-input NOR element 231. The flip-flop 211 is reset by the signal K via the four-input NOR element 230. As a result, the motor stops, and the lowering operation of the door also stops. When the pulse signal K falls, the Q output of the monostable multivibrator 207 rises and the three-input AND element 232 goes high to output the signal L. The signal L is converted into a signal M through the differential circuit 213 and the NOT element 222 and input to the two-input OR element 223. As a result, as described above, the signal F which is the rising command is output through the series of control warnings, and the door is raised, and the door is stopped by the output signal N of the NOT element 217 which is the signal of the upper limit switch 30. In this way, when the door detects an obstacle, the safe operation is assured that the operation stops immediately during the ascending, while the descending stops immediately during the descending, and starts the ascending operation after T ₃ hours. However, when the lower limit limit switch 31 is turned ON, the obstacle detection operation is unnecessarily operated by the obstacles such as small obstacles (stones or sticks) or the bottom surface of the synchronous in the vicinity of the lower limit of the door. The detection operation is immediately inhibited by the two-input NOR element 231, but the signal G which is the falling operation command is reset by the signal of the time delay T ₂ by the integrating circuit 212.

By this control operation, door opening and closing control can be performed safely without inconvenience. Next, the circuit embodiment of the present invention will be described with reference to FIG.

750 is the contact output of the fire accident detection device, 751 is a timer circuit using NE555 (signal), 752 is a one-short circuit using NE555 (signal), 753 to 758 is an inverter element, 759 is a buffer Element, 760-762 are two-input AND elements, 763 ~ 765 are two-input OR elements, 766-768 are three-input AND elements, 769,770 are two-input OR elements, 771 are two-input AND elements, and 772,773 are D-type flip-flops ( 774 to 777 denote transistors. When the output of the AND element 228 is at the high level, the gate is stopped and at the low level, the door is in operation. So this AND element 228

When the door is stopped, the light emitting diodes 665 and 666 are turned off, but the inverter element 753 and the AND element 761 check that there is no door at the lower limit position, and the lighting is continued by the transistor 775 again. In the lower limit position, the light emitting diodes 665 and 666 become extinguished human bodies.

The output of the timer circuit 751 is input to one end of each of the three input AND elements 767 and 768. At one end of each of the three-input AND elements 767 and 768, the operation direction command of the door is input via the inverter elements 756 and 757. The signal at the time of abnormality detection is input to the other end of the three-input AND elements 767 and 768, but is normally at a high level. Therefore, the three-input AND element 768 operates the in-house buzzer 667 while the door is rising through the two-input OR element 763 and the transistor 776.

Similarly, the three-input AND element 767 operates the in-vehicle buzzer 647 while the door is descending through the two-input OR element 764 and the transistor 777.

The control switch 654, the lead switch 650, 652, and the contact 750 are respectively input to the inverter element 754, the two input OR element 765, and the inverter element 755 through a filter circuit. . The FFs 772 and 773 are always cleared when the control switch 654 is OFF. In addition, the FF 772 is cleared by the door operation because a signal during door movement is input to the two-input AND element 762 in addition to the control switch 654.

When the contact 750 is ON, the FF 773 is set via the AND element 760 to set the two-input NOR element 769, the inverter element 758, the two-input OR element 763, 764, and the transistor. The buzzers 647 and 667 are operated via 776 and 777.

The reed switch, i.e., the open gage of the window or auxiliary door, operates the one-shot circuit 752 as the two-input NAND element 771 after the door stops or at the lower limit stop. In other words, the output of the two-input NOR element does not go high until the timer is up, so the output of the three-input AND element does not come out. After the timer is up, signals from the lead switches 650 and 652 are received, and if a detection input is made, the FF 772 is set, and the two-input NOR element 769, the inverter element 758, and the two-input OR are received. The buzzers 647 and 667 are operated via the elements 763 and 764 and the transistors 776 and 777.

As described above, according to the present invention, it is possible to collectively control the operation of the garage door and the processing after the detection of abnormal conditions in the garage, and a very safe garage door control method is achieved, and the contribution to the product is very large.
