Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an emergency control notification device for an elevator that performs communication between the elevator car and the outside and control from the outside when the elevator breaks down.

If an accident such as passengers being trapped in an elevator car occurs due to an elevator malfunction, the passengers will be extremely anxious. In such cases, conventional emergency notification devices have been designed to enable communication between the inside of the elevator car and the manager's room via a private line, and between the elevator car and the elevator service center etc. via a subscriber line. more known.

With this conventional device, it is possible to communicate between the elevator car and the manager's room, but if the manager is not present at the time of an accident, the automatic dialing device captures the subscriber's line and calls the subscriber's telephone at the service center. is automatically called, allowing direct communication between the elevator car and the service center.

However, elevator jamming accidents often occur simultaneously when multiple elevators are installed in parallel in the same building. In such a case, if one elevator car and the service center etc. are connected via a subscriber line and a conversation is established, even if the service center etc. is called in the other elevator car where the accident occurred during that time, the service center etc. The subscriber's line is not connected and calls cannot be made. Moreover, at the time of an accident, the passengers in the elevator car are in a panic state, so the dialogue does not get the point and it takes a long time to finish, so no matter how long they wait, passengers in other elevator cars are unable to communicate and become extremely anxious. Becomes in a state of panic.

Also, even if the service center wants to talk to other elevator cars after talking to one elevator car, this is not possible in the absence of the manager, so the status of the other elevator cars cannot be known. , personnel from the service center must rush to the elevator.

In addition, when the service center disconnects the call without permission and tries to call the manager's office because the conversation for one elevator car is pointless, the call is disconnected for that elevator car, making it very difficult. The subscriber becomes anxious and immediately attempts to call the service center again, resulting in a state where both the subscriber's line and the service center are called, and a connection becomes impossible.

In addition, because the passengers in the elevator car are in a panic state and do not know the technology of elevator equipment, the service center cannot obtain accurate failure information just by talking with the passengers. Accurate measures cannot be taken immediately,
Even simple situations caused by extremely simple causes require a trip to the elevator every time.

In order to solve these drawbacks, the present invention has been developed to solve this problem by providing a service center that can communicate directly with a service center in one elevator car in the absence of a manager, while the subscriber's line remains captured. By making it possible to freely switch the call connection to other elevator cars or to the manager's room, it is possible to avoid a panic situation when an accident occurs in multiple elevator cars at the same time. An object of the present invention is to provide an emergency control notification device for an elevator, which transmits an operation control signal to a service center side, and also transmits an operation control signal from the service center side to elevator mechanical equipment.

A power supply supplies AC100V, and 58 is a battery for use in the event of a power outage.

Next, a concrete example of the operation of the above device will be explained with reference to FIGS. 2 and 3.

(1) When a passenger turns on the activation switch of the communication device 11 in the elevator car 10 where the failure occurred,
When the presence/absence switch of the manager's room is set to the "present" side, the buzzer of the communication device 21 sounds. During this ringing, a ringing tone from the ringing notification section 34 is heard by the speaker of the communication device in the car 10. When the communication device 21 in the manager's room responds, communication becomes possible between the car 10 and the manager's room. Note that if a plurality of cars 10 call the manager's room in parallel, only the first car 10 will be connected. The speaker of the communication device 11 of the other car 10 that has performed the calling operation can hear the conversation between the car 10 and the manager's room.

(2) If the manager's office presence/absence switch 32 is set to the "absent" side but does not respond until a predetermined period of time has elapsed, the notification unit 35 will notify you. The absence tone or absence announcement is from the communication device 1 in the car 10.
It is heard on one speaker.

(3) Auto dialing is started along with a call to the telephone device 21 in the manager's room. That is,
The auto dial section 36 captures the subscriber line 26 and sends out the dial pulse stored in the dial memory 39, and the exchange 27 sends out a calling signal to the subscriber telephone 24 at the service center. In addition, the subscriber line 26 on the manager's room side
If a call is being received, a call collision prevention circuit in the control unit 38 operates and the auto dial unit 36 is not activated. (At this time, the incoming call display section 1 in the car 10
3 will be displayed indicating that a call is being received. ) Also, the public corporation's ring tone or busy tone to the subscriber telephone 24 is heard by the speaker in the car 10 via the line control section 37 and the premises line section 31.

If the subscriber telephone 24 does not respond for a predetermined period of time (for example, 50 seconds), a timer in the control section 38 operates to cancel the call. During this call, a failure signal from the transmitter 41 is sent.
The absence signal is received by the receiving section 54 of the supervisory control device 50, the bell 60 rings, and the contents of the signal are sequentially displayed on the display section 55 and printed on the printer 61. Therefore, information from the elevator side is transmitted even if no one is present at the service center. If the subscriber telephone 24 is answered, conversation becomes possible. As described above, the conversation at this time can be heard through the speaker in the car 10 that arrived after the calling operation.

(4) At the service center, display section 5 indicates that the manager is absent.
5 or printer 61, the subscriber's telephone 24 responds. Further, even after the call to the subscriber telephone 24 is completed, the operator can operate the operating section 52 to call the desired telephone device 21 in the manager's room or the telephone device 11 in the car 10. In addition, on the service center side, if it is thought that an accident has occurred simultaneously in multiple elevator cars 10, for example, the operator operates the changeover switch of the operation unit 52 in the connection device 50 to send a changeover signal and select the desired communication device 11, 21. Switch the call path connection to and talk. When the switching is completed, a completion signal from the transmitting section 41 is received by the receiving section 54 of the connection control device 50, and the number of the elevator car 10 or the number of the manager's room which has been switched and connected is displayed on the display section 55. Buzzers 12 and 29 sound inside the car 10 or in the manager's room that has been switched and connected.

(5) The service center determines the nature of the failure using the display unit 55, printer 61, or through communication, and sends a mechanical control signal from the operation unit 52 to control the mechanical equipment of the elevator. This makes it possible to eliminate as much as possible the waste of dispatching to the elevator one by one.

(6) If the communication devices 11 and 21 remain disconnected in the car 10 or in the manager's room after the conversation ends, the service center operates the recovery switch on the operation unit 52 and sends a recovery signal from the transmitter 53. do. Receiving unit 40 receives this and transmits it to communication device 1.
1 or 21 and the subscriber telephone 24 is opened and restored.

In the above embodiment, it goes without saying that the subscriber telephone 22 in the manager's room may be used in place of the communication device 21.

As explained above, in the present invention, even if one elevator car is in a conversation state, the call can be freely switched from the service center side to another elevator car or the manager's room while the subscriber line is captured. Because of this, it is possible to change the call regardless of the reaction of the passengers in the elevator car who are in a panic state.Moreover, the one elevator car connected to the subscriber line can be switched without breaking the connection. Since line connection failures due to collisions between calls from both sides do not occur, the service center can immediately respond to multiple elevators and the manager's office and take appropriate measures, allowing multiple elevators to It is possible to avoid panic situations when car accidents occur simultaneously, and the service center can automatically and accurately obtain elevator failure information signals. Because we can control the operation of mechanical equipment,
You can also restore the elevator without having to go to the elevator.
