Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an alarm device that sounds when an abnormality occurs in an elevator.

Conventionally, elevator alarms sound when an abnormality occurs in the elevator by operating an emergency bell button or by an abnormality detection signal from the elevator control device, and by operating a reset button provided in the manager's room or elevator machine room, or After a certain period of time, it will be automatically disconnected and the sound will stop.

When the alarm sounds as described above, if there are people near the elevator or in the manager's room, it is effective because the sound of the alarm allows the user to discover an abnormality in the elevator and take appropriate measures.

However, the janitor is not always working in the janitor's office, and there are not always people near the elevators. Therefore, in recent years, when an elevator abnormality occurs, an automatic notification device is used to report the problem via telephone line. , sending pre-recorded messages to the destination and communicating with passengers inside the car.

In this case, the sounding of the alarm unnecessarily gives discomfort to the passengers in the car, the manager, etc., and also has the disadvantage of interfering with conversation.

This invention solves the above-mentioned drawbacks, and is an abnormality alarm for elevators that automatically controls the ringing of an elevator alarm to eliminate discomfort for passengers in the car or the manager, and to eliminate obstacles to conversation. The purpose is to provide equipment.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In Figure 1, 1 is an emergency call button installed inside the car, 2
is an elevator control device, 3 is an elevator alarm installed in the manager's room, 4 is an alarm ringing control device, 5 is an automatic notification device, 6 is a main telephone in the building, 7 is a disconnector, 8 - 13
is a connecting line.

The operation of the emergency notification button 1 or the abnormality detection signal from the elevator control device 2 is sent to the automatic notification device 5 and the alarm sound control device 4, and the automatic notification device 5 is driven.

In this case, the operation signal of the automatic notification device 5 is sent to the alarm sound control device 4, and this signal and the signal from the elevator control device 2 are calculated by the alarm sound control device 4 to cause the elevator alarm 3 to sound. Control.

In Figures 2 and 3, 5A automatically calls and connects to the preset reporting destination, then plays back the voice recorded building name, management number, location, elevator name, etc. A well-known automatic notification device that outputs, + and - are DC power supplies, 15 is an emergency notification relay, 15a and 15b are normally open contacts, 16 is a reset button 17 provided in the manager's room, etc. is a reset relay, 17a is its normally closed contact; 18 is an abnormality detection relay contact that automatically detects and closes the elevator when any abnormal condition occurs; 19
is an automatic notification command relay, 19a to 19d are normally open contacts thereof, 20 is a telephone line closing relay contact that is closed when the telephone line to the outside is closed by the automatic notification device 5,
21 is a telephone line open relay contact which similarly closes when the telephone line is open; 22 is a telephone line close memory relay; 22a to 22c are its normally open contacts; 22d, 22e;
is also a normally closed contact, 23 is a telephone line open memory relay,
23a to 23c are normally open contacts, 24 is a time-limited time relay that operates immediately when energized and returns after a certain period of time when deenergized, 24a is a normally open contact, and 24b is a normally closed contact. , 25 is a time-limited operation and time-limited return type relay that operates after a certain period of time when energized and returns after a certain period of time when de-energized, 25a is its normally closed contact, 25b is also a normally open contact, and 26 and 27 are the normally open contacts. It is resistance.

Next, the operation of this embodiment will be explained.

When the emergency call button 1 is pressed inside the car, the emergency call relay 15 is energized and contacts 15a and 15b are closed o(+)-(1γa) (15a)-C1
The automatic notification command relay 19 is energized by the circuit 9)-(7) and self-maintains by closing the contact 19a.

Further, contacts 19b to 19d are also closed.

By closing the contact point 19d, the automatic notification device 5A is driven,
A report is sent to the maintenance company etc. via the telephone line.

At this time, the telephone line closing relay contact 20 is closed, so (l-) (1 7a) (1 9b) - (20).
-(22) The telephone line closure memory relay '22 is energized by the circuit (-) and self-holds by closing the contact 22a.

At the same time, contacts 22b t 22c are closed, and contacts 22d
t 22e is open.

Further, since the contact 23c is also open, the alarm 3 is not energized and does not sound.

When the above-mentioned notification to the maintenance company etc. is completed and the telephone line is opened, the telephone line open relay contact 21 is closed, so (+
) (1 7a) (1 9b) one (22b)
-(2 1) -(2 3) The telephone line open memory relay 23 is energized by the circuit 1 (-), and self-maintains by closing the contact 23a.

At the same time, contacts 23b and 23c are also closed. Contact point 23b
When is closed, (+) −(1 7a) (1 9b
) −(2 2 b) − (2 3 b) −(2
5a) -(2 4)-(-), the time relay 24 is energized and immediately operates, closing the contact 24a and opening the contact 24b.

Closing of contact 24a causes time relay 25 to operate after a predetermined period of time, opening contact 25a and closing contact 25b.

By opening the contact 25a, the time relay 24 returns after a certain period of time, the contact 24a opens, and the contact 24b closes.

Here, (+) ('f9c) (22c) (23c) - (
24b)(25b)(3)00 circuit is connected and alarm 3 sounds.

By opening the contact 24a, the time relay 25 returns after a certain period of time, the contact 25a closes, and the contact 25b opens.

Therefore, the alarm 3 stops sounding.

Thereafter, the same operation is repeated, and the time relays 24, 2
The alarm 3 sounds at fixed time intervals determined by the 50 time period.

When the administrator presses the reset button 16, the reset
The J-ray 17 is energized and the contact 17a is opened.

As a result, relays 22, 23 and timed relays 24,
25 is deenergized and returns to the initial state.

Although the above description has been made regarding the case where the emergency call button 1 is pressed, it can be easily explained that the same applies when the abnormality detection relay contact 18 is closed.

Also, when emergency call button 1 is pressed, (+) - (1
5 b) -(2 2 d)-(3}-Eρ circuit and when the abnormality detection relay contact 18 is closed, (+)
(1 9c) - (2 2 e) - (3) - (-) circuit closes the telephone line and contacts 22d or 2
It is easy to understand that the alarm 3 will sound until the alarm 2e is released.

Although the circuit shown in FIG. 3 is reset using the reset button 1b, it may also be automatically reset using a relay (not shown) that detects when the elevator has recovered from an abnormality.

Alternatively, a suitable time relay may be used to hold the signal for about one hour and then reset it.

Further, in the embodiment, the automatic notification device 5 is activated when the emergency notification button 1 is pressed, but it may also be possible to enable interaction between an in-car communication device (not shown) and a maintenance company. Needless to say, it can be applied.

Furthermore, while the telephone line is closed, the sound of the alarm device 3 can be easily suppressed without stopping the sound.

As explained above, in this invention, the sound of the alarm is controlled while the automatic notification device reports an abnormality to the outside of the car via the telephone line. can eliminate discomfort,
It is possible to avoid any obstacles during conversation.
