Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of controlling an automatic door for restricting entry into a building or a room by means of a collating device such as a numeric keypad or a card reader.

[0002]

2. Description of the Related Art Conventionally, as such an automatic door, for example, there is one shown in FIG. 8 (JP-A-60-3376).
In this automatic door, a card reader 52 that determines whether or not a key card is valid is installed on the outer surface of a slide-type automatic door 51 installed in a hotel entrance 50, and goes out to return late. The guest who came to see the key card in the card reader 5
When it is determined that the key card is valid,
The doors 51, 51 are opened to allow guests to enter the hotel.

[0003]

In the above automatic door, when it is determined that the key card inserted in the card reader 52 is valid, the doors 51 and 51 are immediately opened to move the guest into the hotel. After the doors 51 and 51 are opened, the doors 51 and 51 are closed regardless of the passage of people in the room after the doors 51 and 51 have been opened. There was a fear of pinching the person who stopped.

Such a problem is caused by, for example, Japanese Patent Laid-Open No. 58-76670.
Installed a safety sensor, as disclosed in
It can be solved by opening the door while the safety sensor is blocked, but by installing this safety sensor, even an outsider who does not have a card can open the safety sensor from the outside. By shutting off, you can drive the automatic door,
A new problem occurs in that the original security function cannot be fulfilled.

[0005]

The technical means of the present invention for solving this problem is to install a collating device around the door of the entrance / exit for determining whether or not the person is an entry permitter. The collation device collates the person who entered the room, and in the automatic door that drives the door when it is determined that the person is the person who has entered the room, a safety sensor is provided to detect a person who stops in the opening / closing path of the door. The sensor can be detected when the door starts to open, and cannot be detected when the door reaches the fully closed position again.

[0006]

According to this means, when the collation device determines that the person is a person who is permitted to enter the room and the door starts to open, the safety sensor can detect the person who is stopped in the opening / closing path of the door and detect the person entering the room. To prevent it from being caught in the door. And
When the safety sensor closes the door again and reaches the fully closed position, the safety sensor cannot detect it. Therefore, the safety sensor does not open and close the automatic door at the fully closed position of the door.

[0007]

[Embodiment] An embodiment in which the present invention is applied to an automatic door installed at the entrance of a condominium will be described below.
FIG. 1 shows a schematic configuration diagram of an automatic door including peripheral devices. A slide type automatic door 1 suspends and supports the doors 1a and 1b on an upper rail in an engine cover 6, and a door engine 7 opens an entrance. It is configured to open and close. Inside the engine cover 6, there are provided a reed switch 8 for detecting the fully closed position of the doors 1a, 1b and an electromagnetic lock 9 for locking the doors 1a, 1b at the fully closed position. When the lock signal is received, the doors 1a and 1b are unlocked, and when the doors 1a and 1b are opened and returned to the fully closed position, the doors are automatically locked.

On the front of the outdoor doors 1a and 1b, a detection sensor 2 for detecting a person who is about to enter the condominium.
However, detection sensors 3 for detecting a person leaving the condominium are provided on the front surfaces of the doors 1a and 1b on the indoor side. The detection sensor 2 is connected to the controller 5 installed in the manager's room in the apartment, and the detection sensor 3 is connected to the control unit 7a (see FIG. 2) of the automatic door 1. Further, safety sensors 10 and 10 are installed at both ends of the outdoor doors 1a and 1b in the opening / closing direction to detect a person who is outside the detection areas of the detection sensors 2 and 3 and stops on the opening / closing path of the doors 1a and 1b. Yes, like the detection sensor 2, it is connected to the controller 5.

The controller 5 is connected to a collation device 4 such as a ten-key 15 for determining whether or not the user is a registrant, a card reader 16 and the like. The collation device 4 is separated from the outdoor entrance. It is installed in the position. An intercom slave 14 that can communicate with the intercom master 13 in the manager's room is installed near the matching device 4. When there is a visitor, the intercom master 13 sends a remote signal to the controller 5 to enter the room. It is possible. Further, the controller 5 is connected to a door opening alarm buzzer 11 that warns of abnormal opening of the doors 1a and 1b, and a schedule timer 12 that switches between a time zone for restricting entry and a time zone for freely entering and exiting.

FIG. 2 shows a control block diagram of the automatic door of FIG. 1, and the parts corresponding to those of FIG. 1 are designated by the same reference numerals.
The controller 5 includes an unlock / door openability determination unit 5a, an unlock /
It includes a door opening signal output unit 5b and a door opening condition setting unit 5c. The unlocking / opening door availability determination unit 5a includes a collation device 4 and a safety sensor 1.
0, the detection sensor 2, the schedule timer 12, the intercom master unit 13, the reed switch 8, and the electromagnetic lock 9 are received. Based on these signals, it is determined whether the doors 1a and 1b can be opened / closed, and unlocked / opened. A door opening signal and an unlocking signal are output from the door signal output unit 5b. In addition, the unlocking / opening possibility determination unit 5a includes a sensor valid timer 5c1 and an alarm timer 5c.
It is connected to the door opening condition setting unit 5a having 2 and makes the detection signal of the detection sensor 2 valid only for the timer time of the sensor valid timer 5c1, and even if the timer time of the alarm timer 5c2 elapses. If the door does not return to the front closed position, the door opening alarm buzzer 11 is activated.
The sensor effective timer 5c1 is set to a time corresponding to the distance from the front surfaces of the doors 1a and 1b to the installation location of the matching device 4, for example, a time required for a general person to walk, and an alarm is issued. The timer 5c2 is set to be approximately the same as the time required for the doors 1a and 1b to open and close.

The unlocking / opening door possibility determining unit 5a is provided with a collating device 4
Upon receiving the entry permission signal from, the sensor valid timer 5c1 of the door opening condition setting unit 5c is activated, and the detection signal of the outdoor detection sensor 2 is validated for this timer time. If there is no ON signal of the detection sensor 2 (indicating that there is a person who wants to enter the room within the detection area of the detection sensor 2) within the timer time of the sensor valid timer 5c1, it is determined that there is no intention to enter the room. , The detection signal of the detection sensor 2 is invalidated. When the ON signal of the detection sensor 2 is received, the unlocking / opening signal output unit 5b outputs an unlocking / opening signal to the control unit 7a of the automatic door 1. As a result, the control unit 7a of the automatic door 1 sends an unlocking signal to the electromagnetic lock 9 and then sends a door opening signal to the door engine 7 to open the doors 1a and 1b.

When the doors 1a and 1b start to open, the reed switch 8 and the electromagnetic lock 9 send an OFF signal to the unlocking / opening possibility determining section 5a of the controller 5, and the unlocking / opening possibility determining section 5 is detected.
In response to the OFF signal from the reed switch 8, a activates the alarm timer 5c2 of the door opening condition setting unit 5c and validates the detection signals of the safety sensors 10 and 10. Within the timer time of the alarm timer 5c2, the doors 1a, 1
If b is returned to the fully closed position and there is no ON signal from the reed switch 8, it is determined that the doors 1a and 1b remain open, and the door open alarm buzzer 11 is activated. Also,
If the occupants are blocking the safety sensors 10 and 10,
Since the unlocking / opening signal output unit 5b continues to output the unlocking / opening signal, the doors 1a and 1b are held in the open state to prevent the occupant from being caught between the doors 1a and 1b.

When the doors 1a, 1b return to the fully closed position and receive the ON signal from the reed switch 8, the safety sensor 1
The detection signals of 0 and 10 are invalidated, and the operation of the door opening alarm buzzer 11 is stopped. Therefore, the safety sensors 10 and 10 are invalid unless a room entry permission signal is received from the collation device 4, and even if an outsider interrupts the safety sensors 10 and 10, the doors 1a and 1b are opened. There is no.

When there is a switching signal from the schedule timer 12, the detection sensor 2 is always enabled, and when the detection sensor 2 detects an occupant, the door 1 is operated as described above.
Drive a and 1b. Further, when there is a person leaving the condominium, the detection sensor 3 on the indoor side detects the person leaving and the control unit 7a of the automatic door 1 is independent of the controller 5.
After releasing the unlocking signal to unlock the electromagnetic lock 9, a door opening signal is sent to the door engine 7 to drive the doors 1a and 1b to exit the condominium.

Next, the operation of one embodiment of the present invention will be described with reference to the flow charts shown in FIGS. 3 to 5 and the time charts shown in FIGS. 6 and 7. First, as shown in FIG. 3, it is determined whether or not the indoor detection sensor 3 is on (step S1). If the detection sensor 3 is off, then the intercom base unit 13 in the manager's room is remoted. It is determined whether or not there is a signal (step S2). If there is no remote signal from the intercom base unit 13, the collation device 4
It is determined whether or not there is an input operation to (step S
3) If there is no input operation, the above operation is repeated again.

In step S3, if there is an input operation to the collation device 4, the input data is collated with the data registered in advance, and whether or not the person who is about to enter the condominium is a registrant. Is determined (step S
4). If the user is not a registered person, the process returns to step S1 and the above operation is repeated. If it is determined that the user is a registrant, the sensor valid timer 5c1 is activated (step S
5). In step S2, if there is a remote signal from the intercom master unit 13 in the manager's room, the sensor valid timer 5c1 is used as in the case of determining that the user is a registrant.
Operate.

As a result, the detection signal of the detection sensor 2 becomes the timer time T1 (for example, as shown in the time chart of FIG. 6).
Only 60 seconds) is valid. Then, it is determined whether or not the sensor valid timer 5c1 is up (step S6), and it is determined whether or not the outdoor detection sensor 2 is turned on (step S7). When the detection sensor 2 is determined to be off in step S7, it is determined again in step S6 whether or not the sensor valid timer 5c1 has timed out, and the above operation is repeated until the timer time T1 times up. .. When the occupant approaches the front of the doors 1a and 1b and the detection sensor 2 is turned on during the timer time T1 of FIG. 6, the detection sensor 2 is detected in step S7.
Is determined to be ON, an unlocking / opening signal is output (step S8), and the doors 1a and 1b are opened (step S8).
9) Allow entry into the condominium.

If the detection sensor 2 does not detect an occupant during the timer time T1 of the sensor valid timer 5c1, it is determined in step S7 that the detection sensor 2 is off, and in step S6. When the timer time T1 is up, it is determined that there is no intention to enter the room, and the operations of steps S1 to S5 are repeated again.

When the doors 1a and 1b start to open, the reed switch 8 for detecting the fully closed state of the door is turned off as shown in the time chart of FIG. 6, and accordingly the safety sensor 1
0 and 10 enable the detection signal and alarm timer 5
c2 is operated for the timer time T2 (step S1
0). Following this, as shown in FIG. 4, it is judged whether or not the sensor effective timer 5c1 has timed out (step S11), and if not, the alarm timer 5
It is determined whether or not c2 is up (step S
12) If the time is not up, it is determined whether the detection sensor 2 is on (step S13). That is, it is determined whether or not an occupant has stopped in front of the doors 1a and 1b. If not stopped, safety sensor 1
It is determined whether 0 and 10 are on (step S1
4). That is, it is determined whether or not there is a person standing in the opening / closing path of the doors 1a and 1b. If the doors 1a and 1b have not returned to the open / close path, it is determined whether or not the doors 1a and 1b have returned to the fully closed position and the reed switch 8 is on (step S
15) If there is an ON signal from the reed switch 8, it is judged that the person has entered the apartment, and the sensor effective timer 5
The operation of c1 is stopped (step S16). Therefore, as shown by the broken line in FIG. 6, the remaining timer time T1 of the sensor valid timer 5c1 is reset, the detection signal of the detection sensor 2 is invalidated, and entry of anyone other than the registered person is blocked.

If the occupant remains at the entrance, it is determined in step S13 that the detection sensor 2 is on, so the unlocking / opening signal continues to be output (step S19), and the door is opened. A door open signal is sent to the engine 7 to hold the doors 1a and 1b in the open state (step S2).
0). Then, again in step S11, it is determined whether or not the sensor valid timer 5c1 is up, and the above operation is repeated until the time is up. During this operation, the timer time T2 of the alarm timer 5c2 is set to the time required to open and close the doors 1a and 1b, and therefore shorter than the timer time T1 of the sensor valid timer 5c1 as shown in the time chart of FIG. , In step S12, the time expires before the sensor effective timer 5c1. For this reason, the door opening alarm buzzer 11 is sounded (step S18) to notify the occupant that the doors 1a and 1b are in the open state, and promptly enter the room.

If the person entering the room is out of the detection area of the detection sensor 2 and is standing still in the opening / closing path of the doors 1a, 1b, it is determined in step S14 that the safety sensors 10, 10 are on, and the sensor is effective. Until the timer 5c1 times out, the above operation is repeated until the doors 1a, 1b
Is kept open to prevent the person entering the room from being caught between the doors 1a and 1b. At this time, in step S12, when the timer time T2 of the alarm timer 5c2 has expired, the door open alarm buzzer 11 is sounded in the same manner as described above, and it is notified to the occupants that the doors 1a and 1b remain open. Notify me and encourage early entry.

When a person who has stopped in the detection area of the detection sensor 2 or a person who has stopped in the opening / closing path of the doors 1a and 1b enters the apartment, the detection sensor 2 and the safety sensor 10 are turned off. So
In step S15, it is determined whether the doors 1a and 1b have returned to the fully closed positions and the reed switch 8 is on. If it is on, the valid timer 5c1 is determined in step S16.
Then, as shown in the time chart of FIG. 7, the operation of the door opening alarm buzzer 11 is stopped (step S
17). In this state, since the safety sensors 10 and 10 are disabled, even if an outsider is in the detection area of the safety sensors 10 and 10, it is possible to prevent an outsider from entering.

If the doors 1a, 1b do not return to the fully closed position due to the obstacle, it is continuously determined that the reed switch 8 is off in step S15. Therefore, unless the obstacle is removed, the process proceeds to step S18. The door open alarm buzzer 11 continues to sound to notify the abnormal opening of the doors 1a and 1b.

When the person entering the room is detected by the detection sensor 2 just before the timer time T1 of the sensor effective timer 5c1 is up (YES in step S7), steps S8, S9 and S10 are executed to open the door 1a. 1b
Is opened, the alarm timer 5c1 is started, and the safety sensors 10 and 10 are validated. However, since the timer time T1 of the sensor valid timer 5c1 is immediately expired, step S11
At, it is determined that the sensor valid timer 5c1 has timed up. At this time, if the time required for the doors 1a and 1b to open and close has not yet elapsed, the alarm timer 5c2 has not expired (the determination in step S21 is NO), and the person occupying the door 1a, If it remains stopped before 1b, the safety sensors 10, 10
Is still off (No in step S22), the detection signal of the detection sensor 2 becomes invalid during the opening / closing operation of the doors 1a and 1b, and the occupant is not detected by the detection sensor 2 and the door is not detected. 1a and 1b return to the fully closed position,
When the reed switch 8 detects this return (Yes in step S23), it becomes impossible to enter the room.

Before the doors 1a and 1b are returned to the fully closed position, the occupants of the room shut off the safety sensors 10 and 10 (step S22).
If YES, the unlocking / opening signal is continuously output (step S24), the opening signal is sent to the door engine 7, and the doors 1a and 1b are maintained in the open state (step S25). This operation is repeated while the occupant shuts off the safety sensors 10 and 10. However, when the time required to open and close the doors 1a and 1b has passed, the timer time T2 of the alarm timer 5c2 is increased (determination in step S21 is made. (Yes), the opening alarm buzzer 11 is sounded (step S26) to inform that the door is in the open state, and prompt the occupants to enter the room early.

Then, the occupants enter the apartment,
When the reed switch 8 detects that the doors 1a and 1b have reached the fully closed position, the doors 1a and 1b are detected in step S23.
Is determined to be closed, and the operation of the door opening alarm buzzer 11 is stopped in step S17. In this state, since the safety sensor 10 is disabled, the safety sensor 10, 10 is not blocked by an outsider, and the outsider's intrusion can be prevented in the same manner as above. If the doors 1a and 1b are open due to an obstacle, step S23 is performed.
Since it is determined that the reed switch 8 is off in step S26, the alarm buzzer 11 is sounded in step S26, and the door 1
Notify abnormal release of a and 1b.

When there is a person who leaves the condominium, the indoor detection sensor 3 is detected in step S1 of FIG.
Is determined to be on, and as shown in FIG. 5, an unlocking / opening signal is immediately output (step S27). As a result, the locked state of the electromagnetic lock 9 is released, and the door engine 7 opens and closes the doors 1a and 1b (step S28).
The alarm timer 5c2 is activated (step S29). As long as the detection sensor 3 and the safety sensors 10 and 10 are on, the doors 1a and 1b are kept open and the alarm timer 5
After the timer time T2 of c2 has expired, sounding the door open alarm buzzer 11 to warn the leaving person to leave early is processed in steps S30 to S36 similar to steps S12 to S18.

[0028]

As described above, according to the present invention, the safety sensor for detecting a person who stops in the opening / closing path of the door can be detected when the door starts to open, and the door reaches the fully closed position again. At this time, the safety sensor exerts its original function as a safety sensor only when the door is driven by the collation device, and once the door reaches the fully closed position, It is possible to prevent the door from being driven and prevent the entry of anyone other than the registered person.
