Further, the car room 6 is provided with a car door 19 on the side facing the landing door 20. Here, the car door 19 and the landing door 20 are collectively referred to as a door 18.

Further, the car control panel 10 and the door motor 21 are disposed on the upper outer wall of the car room 6 of the elevator 1. The on-car control panel 10 rotates the door motor 21 based on a control signal from the elevator control panel 11, and controls the opening and closing of the door 18 interlocked with the rotation of the door motor 21.
Further, the rotation of the electric motor 22 of the hoisting machine 23 is controlled by the elevator control panel 11, and the car 5 is a friction generated between the driving sheave 24 and the main rope 27 that are rotationally driven by the torque of the electric motor 22. The inside of the hoistway 4 is raised and lowered using force.

  In the car room 6, a destination floor button, a door closing button, and a door opening button (none of which are shown) for the user of the elevator 1 getting into the car room 6 to select a desired floor of the car 5 are shown. A car operation panel 28 having the above is disposed.

In addition, for example, landing call buttons 29a to 29d, speakers 30a to 30d, and hall information 31a to 31d are arranged as peripheral devices in each of the landings 3 on the first to fourth floors of the elevator 1 installed in a building on the fourth floor. It is installed.
As for the landing call buttons 29a to 29d, a landing call button 29a only for the destination direction to the upper floor is arranged on the first floor, and a landing call button 29d only for the destination direction to the lower floor is arranged on the fourth floor. In addition, on the second and third floors, landing call buttons 29b and 29c that can specify destinations in both directions of the upper and lower floors are arranged, respectively.
The hall information 31a to 31d visually provides information to the user of the elevator 1 waiting at the landing 3 on each floor, and is composed of various displays, electric bulletin boards, and the like.

Next, electrical connections between the components of the elevator 1 and their functions will be described.
The elevator control panel 11 has an arithmetic control unit 13 and an input / output interface 12. The arithmetic control unit 13 includes a CPU 14 as arithmetic control means, a RAM 15 used in a working area when the CPU 14 performs arithmetic control, a ROM 16 in which a program for controlling the elevator 1 is stored, and a timer 17.

The input / output interface 12 of the elevator control panel 11 and the CPU 14, RAM 15, ROM 16 and timer 17 are connected via a common bus 35.
The CPU 14 can perform computation using the RAM 15 based on the contents of the program stored in the ROM 16.
The input / output interface 12 enables transmission / reception of information between the arithmetic control unit 13 and the peripheral devices connected to the elevator control panel 11 and the on-car control panel 10.

Further, the CPU 14 can arbitrarily start and reset the timer 17.
Further, the car control panel 10 is connected to the elevator control panel 11 by a cable 34a. Further, the car control panel 10 is connected to the door motor 21 by a cable 34b. As described above, the car control panel 10 controls the rotation of the door motor 21 based on the control signal received from the elevator control panel 11. As a result, the opening / closing of the door 18 is controlled by the elevator control panel 11 via the car control panel 10.

The elevator control panel 11 is connected to the hoisting machine 23 by a cable 34c, and the rotation of the electric motor 22 incorporated in the hoisting machine 23 is controlled by the elevator control board 11.
Further, the elevator control panel 11 is connected to the landing call buttons 29a to 29d, the speakers 30a to 30d, and the hall information 31a to 31d via cables 34d.

The hall call buttons 29a to 29d, the speakers 30a to 30d, and the hall information 31a to 31d can individually transmit and receive data to and from the elevator control panel 11.
For example, when any of the landing call buttons 29a to 29d is pressed by the user of the elevator 1, the call information corresponding to the pressed landing call buttons 29a to 29d is transferred to the RAM 15 of the elevator control panel 11 via the cable 34d. Registered (received).

  And CPU14 transmits the control signal which rotates the electric motor 22 to the direction which raises / lowers the cage | basket | car 5 to the hoisting machine 23 based on the information of the call by the registered landing call button 29a-29d. .

  Further, the elevator control panel 11 can drive and control the speakers 30a to 30d and the hall information 31a to 31d, and can perform any notification by announcement or display.

Further, the elevator control panel 11 is connected to the car operation panel 28 via a cable 34e.
Then, when the user of the elevator 1 getting into the car room 6 operates the car operation panel 28 and the destination floor button, the door closing button, and the door opening button are pressed, a call by the destination floor button, the door closing button And a signal (information) corresponding to the door opening button is registered in the RAM 15 of the elevator control panel 11. Further, the CPU 14 performs a control signal for causing the door 18 to open and close and the car 5 to move up and down based on the information corresponding to the call by the registered destination floor button, the door close button and the door open button. Is transmitted to the car control panel 10 and the hoisting machine 23.

Although not described in detail, a cam (not shown) that moves together with the car door 19 is fixed to the upper end of the car door 19, and the car door 19 is attached to a fixed portion above the car door 19. There are provided a well-known full-open switch 32 and a full-close switch 33 that are engaged with the cam when fully opened and fully closed to detect that the car door 19 is fully opened or fully closed.
The fully open switch 32 and the fully closed switch 33 output a signal (ON signal) when the car door 19 is fully opened or fully closed and engaged with the cam.

The fully open switch 32 and the fully closed switch 33 are connected to the elevator control panel 11 via the cable 34f. When the door 18 is fully opened or fully closed, the ON signal is taken into the RAM 15 of the elevator control panel 11, respectively.
As a result, the CPU 14 can recognize the full opening and the full closing of the door 18.

Next, the opening / closing control of the door 18 of the elevator 1 will be described.
First, it is assumed that the car 5 is stopped on the third floor and the door 18 is being opened.
Also, the elevator operation user 28 who has already entered the car room 6 on the lower floor side operates the car operation panel 28 and calls the RAM 15 of the elevator control panel 11 so that the destination of the car 5 is directed to the fourth floor. It shall be registered.
When the door 18 is fully opened, an ON signal from the fully open switch 32 is received by the elevator control panel 11, and the CPU 14 of the elevator control panel 11 starts counting of the timer 17.

  When the count of the timer 17 has elapsed (for example, 5 seconds), or when the door closing button of the car operation panel 28 is pressed by the user of the elevator 1 in the car room 6, the elevator control panel 11 A control signal for closing the door at a normal speed (for example, 0.3 m / sec) is transmitted to the car control panel 10, and the car control panel 10 turns the door motor 21 so as to close the door 18 at the normal speed. Control.

  Here, when the landing call button 29c is not operated by a user of another elevator 1 at the landing 3 on the stop floor of the car 5 during the closing operation of the door 18, the closing operation of the door 18 at the normal speed is as follows. It continues until the door 18 is fully closed. When the elevator control panel 11 receives the ON signal of the fully closed switch 33, the CPU 14 transmits a control signal for rotating the electric motor 22 in the direction to carry the car 5 to the fourth floor to the hoisting machine 23. Then, the car 5 is moved to the fourth floor.

Next, the operation when the landing call button 29c is pushed by the user at the landing 3 on the stop floor of the car 5 during the closing operation of the door 18 will be described.
When a call by the landing call button 29c is registered in the elevator control panel 11 during the door closing operation, the CPU 14 compares the direction of the call by the landing call button 29c with the current destination direction of the car 5. Yes. When the CPU 14 determines that the direction of the call by the landing call button 29c is the same as the current destination direction of the car 5, the reversing door is opened and the user of the elevator 1 gets into the car room 6.

When the door 18 is fully opened and the ON signal of the fully open switch 32 is received by the elevator control panel 11, the timer 17 starts counting.
When the count of the timer 17 has elapsed, or when the user of the elevator 1 in the cab 6 has pushed the door close button of the car operation panel 28, the CPU 14 controls the door 18 to close. Is transmitted to the control panel 10 on the car, and the door 18 is fully closed. At this time, the count of the timer 17 is reset.
Here, the waiting time is defined as the time from when the door 18 is fully opened until the door call button 29c of the elevator 1 or the car operation panel 28 is not automatically closed.

  If the CPU 14 determines that the current destination direction of the car 5 is different from the direction of the call by the pressed landing call button 29c, the CPU 14 uses the speaker 30c and hall information 31c disposed on the stop floor of the car 5. Operate and let the message “I will go up” be announced by voice or display. That is, the current destination direction of the car 5 is notified to the user of the elevator 1. Moreover, the door closing speed of the door 18 is decelerated to a predetermined speed (for example, 0.2 m / sec), and the time until the door 18 is fully closed is increased.

  Here, in the elevator 1 in the door closing operation, when the user of the elevator 1 who wants to go to the fourth floor is in a hurry, the place call button 29c in the same destination direction as the destination direction of the current car 5 should be pushed. It is assumed that the landing call button 29c in the destination direction opposite to the destination direction of the current car 5 is erroneously pressed. It is also assumed that another user of the elevator 1 assumes that the destination direction of the car 5 is the lower floor without permission and presses the landing call button 29c in the destination direction opposite to the destination direction of the current car 5. The

  At this time, a message such as “I will go up” is notified to the user of the elevator 1, so that the user of the elevator 1 recognizes the current destination direction of the elevator 1. Furthermore, the time until the door 18 is fully closed is increased, and the user of the elevator 1 can move to the current destination of the car 5 except when the landing call button 29c is pushed just before the door 18 is fully closed. The platform call button 29c in the same direction as the direction can be pressed again to get into the cab 6 with the inverted door open.

Next, the operation flow of the elevator 1 will be described with reference to FIG.
In FIG. 3, steps 101 to 115 are denoted as S101 to S115 for convenience.
In the initial state, the car 5 is stopped on the lowest floor or a floor other than the top floor, for example, the third floor, and a control signal for opening the door 18 is transmitted from the elevator control panel 11 to the car upper control panel 10. Is open.

First, in step 101, the CPU 14 of the elevator control panel 11 determines whether or not an ON signal from the fully open switch 32 has been received.
If the CPU 14 determines in step 101 that the ON signal of the fully open switch 32 has not been received, step 101 is repeated until an ON signal is received.
When the CPU 14 determines in step 101 that the ON signal of the fully open switch 32 has been received, the CPU 14 starts counting of the timer 17 (step 102).
Subsequent to step 102, in step 103, it is determined whether or not a close button signal of the car operation panel 28 has been received.

If the CPU 14 determines in step 103 that the close button signal for the car operation panel 28 has been received, the process proceeds to step 105.
If the CPU 14 determines in step 103 that the close button signal for the car operation panel 28 has not been received, the process proceeds to step 104.
In S104, the CPU 14 determines whether or not the count of the timer 17 has elapsed a standby time (for example, 5 seconds).

If the CPU 14 determines in step 104 that the standby time has elapsed, the CPU 14 transmits a control signal for operating the door 18 in the closing direction to the car control panel 10 and moves the door 18 in the normal direction (in the closing direction). For example, it is operated at 0.3 m / sec) and the timer 17 is reset (step 105).
In step 106 following step 105, the CPU 14 determines whether or not a call of the stop call button 29c on the stop floor of the car 5 is registered.
If the CPU 14 determines in step 106 that the call for the landing call button 29c is not registered, the door closing operation at the normal speed is continued (step 107).
Following step 107, in S108, the CPU 14 determines whether or not an ON signal of the fully closed switch 33 has been received.

If it is determined in step 108 that the CPU 14 has not received the ON signal of the fully closed switch 33, the process returns to step 106.
If it is determined in step 108 that the CPU 14 has received the ON signal of the fully closed switch 33, the process proceeds to step 114.

If it is determined in step 106 that the call of the stop call button 29c on the stop floor of the car 5 is registered by the CPU 14, the CPU 14 determines whether the current destination direction of the car 5 and the call direction by the landing call button 29c are the same. It is determined whether or not (step 109).
In step 109, when the CPU 14 determines that the destination direction of the car 5 and the direction of the call by the pressed landing call button 29c are the same, the CPU 14 causes the control panel 10 on the car 10 to open the door 18. A signal is transmitted, the door 18 is moved in the opening direction (step 115), and the process returns to step 101.

In step 109, if the CPU 14 determines that the direction of the destination of the car 5 and the direction of the call by the pressed landing call button 29c are different, the CPU 14 sends a control signal for decelerating the door closing speed to the control panel 10 on the car. The door closing speed is reduced to a predetermined speed (for example, 0.2 m / sec) (step 110).
Following step 110, in step 111, the hall information 31c and the speaker 30c are actuated, and for example, a message such as “I will go up” is displayed by voice or display, etc., to the elevator 1 user at the landing 3 Then, it is recognized that the destination direction of the current car 5 is different from the operated hall call button 29c (step 111).

In step 112 following step 111, the CPU 14 determines whether or not the landing call button 29c having the same destination as the destination direction of the current car 5 has been pressed.
If the CPU 14 determines in step 112 that the landing call button 29c having the same destination as the current destination direction of the car 5 has been pressed, the process proceeds to step 115.
If the CPU 14 determines in step 112 that the landing call button 29c having the same destination as the current destination direction of the car 5 is not pressed, the process proceeds to step 113.
In step 113, the CPU 14 determines whether an ON signal of the fully closed switch 33 has been received.
If it is determined in step 113 that the ON signal of the fully closed switch 33 has not been received, the process returns to step 111.
If it is determined in step 113 that the ON signal of the fully closed switch 33 has been received, the CPU 14 controls the hoisting machine 23 to move the car 5 in the destination direction (step 114).

  In the first embodiment, in the elevator 1 in which the car 5 is stopped between the top floor and the bottom floor and the door 18 is closed, the direction of the call by the landing call button 29c and the destination direction of the current car 5 The CPU 14 of the elevator control panel 11 operates the speaker 30c and the hall information 31c to notify the user of the elevator 1 at the landing 3 of the current destination direction of the car 5, and at the same time the door closing speed Is slowing down.

  Therefore, according to the first embodiment, the destination direction of the current car 5 is inadvertently given to the user of the elevator 1 who has erroneously pressed the landing call button 29c of the destination opposite to the current destination direction of the car 5. I can inform you. Further, by reducing the door closing speed, the user of the elevator 1 can press the landing call button 29c in the direction of the destination of the car 5 again before the door 18 is fully closed. Since it is opened, the user can get into the cab 6. Accordingly, the elevator 1 can be operated without giving a sense of frustration to the user of the elevator 1 who has erroneously registered the call by pressing the landing call button 29c in the destination direction opposite to the destination direction of the current car 5. It can be carried out.

  In the first embodiment, when the elevator control panel 11 determines that the direction of the call by the pressed landing call button 29c is opposite to the current destination direction of the car 5, the direction of the destination direction of the car 5 is determined. Although it was described as performing both notification and deceleration of the door closing speed, even if only one of the notification of the destination direction of the car 5 and the deceleration of the door closing speed is performed, it is given to the passenger. A feeling of agitation can be reduced.

Embodiment 2. FIG.
4 and 5 are operation flow diagrams of an elevator provided with an elevator control apparatus according to Embodiment 2 of the present invention.

The configuration of the elevator 1 is the same as that of the first embodiment.
Next, control during the door closing operation of the elevator 1 will be described.
Note that the car 5 is stopped on the third floor as in the first embodiment.

When the door call button 29c in the direction opposite to the destination direction of the current car 5 is pushed by the user of the elevator 1 at the landing 3 on the stop floor of the car 5 while the door 18 is closed, the first embodiment As explained, the user is notified of the current destination direction.
However, if the user of the elevator 1 does not notice the notification, it is easily conceived that the user can continue to operate the hall call button 29c in the reverse direction.

For example, the user of the elevator 1 at the landing 3 on the stop floor of the car 5 expects the door 18 to be opened, and continues to press the landing call button 29c in the direction opposite to the destination direction of the current car 5, It is expected that the landing call button 29c is repeatedly hit many times.
Therefore, while the door is closed, the user of the elevator 1 at the stop 3 of the stop floor of the car 5 repeatedly hits or keeps pushing the stop call button 29c in the destination direction opposite to the current car 5 destination direction. If it is, the CPU 14 of the elevator control panel 11 determines that the user of the elevator 1 is erroneously pressing the landing call button 29c in the direction opposite to the current destination direction of the car 5, and based on the determination result The door 18 is controlled to be opened and closed.

  That is, when the landing call button 29c in the direction opposite to the destination direction of the car 5 is pressed, the timer 17 starts counting, and further, the number of call registrations (ON / OFF times) by the landing call button 29c is counted. When a call by the landing call button 29c is registered (received) for a predetermined number of times (for example, three times) or more while the first predetermined time (for example, 1.5 seconds) elapses, the elevator 1 It is determined that the user has mistakenly pressed the hall call button 29c in the destination direction opposite to the current destination direction of the car 5, the door 18 is opened, and the user is put in the car room 6. Yes.

  Further, the elevator control panel 11 determines that the user of the elevator 1 when the call by the landing call button 29c in the destination direction opposite to the destination direction of the car 5 is continuously registered for a second predetermined time (for example, 2 seconds) or more. However, it is determined that the hall call button 29c in the destination direction opposite to the current destination direction of the car 5 is erroneously pressed, the door 18 is opened, and the user is placed in the car room 6.

The other elevators 1 are controlled in the same manner as in the first embodiment.
Hereinafter, the control operation of the elevator 1 will be described with reference to FIGS. 4 and 5.
4 and 5, steps 201 to 217 are referred to as S201 to S217 for convenience.
In FIG. 4, Step 201 to Step 209 and Step 215 to Step 218 are the same as Step 101 to Step 109 and Step 112 to Step 115 in FIG.

  Further, in the initial state, as described in the operation flow of the first embodiment, the control signal for opening the door 18 is stopped when the car 5 is stopped on the lowest floor or a floor other than the top floor, for example, the third floor. It is transmitted from the elevator control panel 11 to the car control panel 10 and the door 18 is in an opening operation.

In step 210, the door closing speed is decelerated and at the same time, the timer 17 starts counting.
In step 211 following step 210, the CPU 14 operates the speaker 30c or the hall information 31c to notify the destination direction of the car 5.
Following step 211, in step 212, the CPU 14 registers a call by the stop call button 29c on the stop floor of the car 5 for a predetermined number of times (for example, three times) or more within a first predetermined time (for example, 1.5 seconds). (Whether ON / OFF) is determined.

  If it is determined in step 212 that the call by the landing call button 29c has been registered a predetermined number of times or more by the CPU 14, the CPU 14 transmits a control signal for operating the door 18 in the opening direction to the control panel 10 on the car, 18 is opened and the speaker 30c and hall information 31c are informed of the current destination direction of the car 5 (step 214), and the process returns to step 101.

If it is determined in step 212 that the call by the landing call button 29c has not been registered a predetermined number of times or more, the CPU 14 proceeds to step 213.
In step 213, the CPU 14 determines whether or not the call by the landing call button 29c has been continuously registered for a second predetermined time (for example, 2 seconds) or more.

When it is determined in step 213 that the call by the landing call button 29c has been continuously registered for the second predetermined time or longer by the CPU 14, the CPU 14 sends a control signal for operating the door 18 in the opening direction to the control panel 10 on the car. Then, the door 18 is opened and the current destination direction of the car 5 is re-notified (step 214), and the process returns to step 101.
If it is determined in step 213 that the call by the landing call button 29c has not been registered continuously for the second predetermined time or longer, the process proceeds to step 215.

  In the second embodiment, the car 5 is stopped between the uppermost floor and the lowermost floor. Further, in the elevator 1 during the door closing operation, the CPU 14 of the elevator control panel 11 is opposite to the current destination of the car 5. When it is determined that the call by the destination direction call button 29c has been registered a predetermined number of times within the first predetermined time, or when it is determined that the call has been continuously registered for the second predetermined time or more, the elevator control The CPU 14 of the board 11 determines that the user of the elevator 1 is operating the landing call button 29c in the direction opposite to the destination direction of the car 5 and opens the door 18 again.

Therefore, according to the second embodiment, the destination call button 29c in the direction opposite to the destination of the current car 5 is operated while the elevator 1 is closed without noticing that the destination of the current car 5 has been notified. The elevator 1 can be operated without giving a feeling of frustration to the user of the elevator 1 who is doing this.
In addition, by re-notifying the current destination direction of the car 5 by the notification means together with the re-opening, the user of the elevator 1 can be made aware of the current destination direction of the car 5, so that the elevator user can be relieved.
