Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator communication device, and more particularly, to an elevator communication device which invalidates the response of an emergency call button due to an erroneous operation of a passenger.

[0002]

2. Description of the Related Art In an elevator, a telephone is installed above a driver's panel in a car, and when an emergency call button of the telephone is operated, a bell of a telephone installed in a monitoring center rings, It is possible to talk with the observer in the surveillance center and the passengers in the car.

By the way, as disclosed in, for example, Japanese Utility Model Laid-Open No. 56-151263, a plurality of operation buttons, that is, a car call button, a door open button, and a door close are provided on the driver's panel. Buttons are provided. Therefore, passengers may accidentally press the emergency call button where they should press these operation buttons, and as a result, the telephone of the monitoring center is called, which is not only a wasteful call,
When the passenger who pressed the emergency call button gets out of the car, the supervisor at the monitoring center cannot communicate, so it is determined that an accident has occurred and a maintenance worker is requested to dispatch to the elevator building. There was a systematic problem.

For this reason, for example, Japanese Utility Model Laid-Open No. 62-8926.
As disclosed in Japanese Patent Publication No. 6, there is a communication device that calls a communication device of a monitoring center when the emergency call button is pressed for a predetermined time or longer. Therefore, it is described that the emergency call button is continuously pressed near the emergency call button. Display panel is provided.

[0005]

By the way, the emergency call button is used when a failure such as a power failure occurs, the car suddenly stops, and passengers are trapped in the car.
In such an emergency state, the passenger may be very excited and may not look at the display board, and the passenger may not press the emergency call button for a predetermined time or longer as described above. Therefore, it is trapped in the cage for a long time, which is a problem.

In view of the above-mentioned drawbacks, the present invention is to provide an elevator communication device for preventing the erroneous operation of the emergency call button and for surely calling the communication device of the monitoring center in the event of a failure.

[0007]

To achieve this object, the present invention provides a telephone in the elevator car and a monitoring center, and when the emergency call button installed in the car is operated, the monitoring center is operated. In the elevator communication device for calling the communication device of No. 3, when a voice guidance device is provided in the car and the emergency call button is operated, a message requesting the operation of the emergency call button again is issued via the voice guidance device. The system is provided with means for broadcasting and means for calling the telephone of the monitoring center when the emergency call button is operated within a predetermined time after broadcasting this message.

[0008]

According to the present invention, it is assumed that, for example, a car in which a power failure has occurred is stopped at an intermediate floor and a trapping failure has occurred.
Therefore, the passenger calls the telephone of the monitoring center, so when he presses the emergency call button, the voice guidance device will say, "Press the emergency call button again within 10 seconds to call the monitoring center."
Then, when the passenger hears this message and presses the call button again, the passenger calls the telephone of the monitoring center and the passenger can interact with the monitoring staff of the monitoring center.

Further, even if the passenger mistakenly operates the operation button at the driving place and presses this emergency call button during normal operation, he / she does not press the emergency call button again by listening to the message. Never call the phone.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 2 is a front view of the operation panel in the car.

In the figure, 1 to 4 are car call buttons on the 1st to 4th floors, 5 and 6 are door open and close buttons, CB is an emergency call button provided above the door close button 6, and SP is A voice guidance device provided in the vicinity of the emergency call button, and IN is a telephone communication device provided in the upper part of the driver's panel.

FIG. 1 is an electrical connection diagram of an elevator communication device according to the present invention.

In the figure, P and N are DC power supply terminals and CB.
Is an emergency call button, AX is a relay that is energized when the emergency call button is pressed, AXa1 and AXa2 are its a contacts, M1 is a relay that is energized when the contact AXa1 is closed, M1a1,
M1a2 is its a-contact, and T1 and T2 start counting when the contact M1a2 is closed. T1 is a timer that is activated 10 seconds later and T2 is activated 20 seconds later. T1a1 is the a-contact of timer T1, T2b1 and T2b2 are the timers T2. b contact, M2 is a relay energized when contact AXa2 and contact T1a are closed, M2a1 and M2a2 are its a contact, M2b is its b contact, SP is a voice guidance device that broadcasts a message when contact M1a2 is closed. , FS is a calling device whose contact point M2a2 calls a calling device of a monitoring center (not shown),
FSb is a contact b of a relay that is energized when the calling operation FS responds, and SP is a voice guidance device that broadcasts a message when the contact M1a2 is closed. For example, "If the emergency call button is pressed again within 10 seconds, monitoring is performed. I will call the center. "

Next, the operation of this embodiment will be described.

Now, a power outage occurs, the car suddenly stops,
Suppose a containment failure occurs. When the passenger in the car pushes the emergency call button CB for calling the telephone of the monitoring center, the circuit of P-CB-AX-N is formed and the relay AX is formed.
Is biased, the contact AXa1 closes, and P-AXa1-T2
The relay M1 is energized by the circuit of b1-M2b-M1-N and is self-held via the contact M1a1.

At the same time, the contact M1a2 is also closed, and the timer T
1. The timer T2 starts counting and is broadcast from the voice guidance device SP, "If the emergency call button is pressed again within 10 seconds, the monitoring center is called." Then, when the passenger pushes the emergency call button CB again, the relay AX is activated again, and after 10 seconds have already elapsed, the timer T1 is activated and the contact T1 is reached.
Since a is closed, P-AXa2-T1a-T2b2
The -FSb-M2-N circuit is formed, the relay M2 is energized and self-held via the contact M2a1. Contact point M
When 2a2 is closed, the calling device FS operates to call the alarm of the monitoring center (not shown), and the monitoring staff at the monitoring center can pick up the handset and interact with the passengers in the car. When the handset is picked up, the hook switch FSb opens and the relay M2 is deenergized, and the contact M2b
1, the relay M1 is deenergized and the initial state is restored.

Next, it is assumed that the passenger accidentally presses the emergency call button CB at a place where the door close button 6 should be pressed. Similarly to the above, the relay M1 is energized and the message is broadcast from the voice guidance device SP. However, in this case, the passenger mistakenly presses the emergency call button CB, and thus does not press the emergency call button CB again.

Therefore, the relay M2 is invalid and does not call the monitoring center.

After 20 seconds, the timer T2 is energized, the contact T2b1 is opened, the relay M1 is deenergized, and the initial state is restored.

In the above, the emergency call button C
Although the case of pressing B has been described, the monitoring center is not called even when the passenger mischievously presses the emergency call button CB and gets out of the car.

[0022]

As described above, according to the present invention, when a passenger pushes the emergency call button, a predetermined message is broadcast, and when the emergency call button is pushed again, the monitoring center is called. There is an effect that the erroneous operation or the mischievous operation can be surely prevented.
