A failure detector 12i for detecting a failure of the car 12a is provided.

Next, the operation of the elevator emergency notification monitoring device having the above configuration will be described.

Intercom 12b of elevator car 12
In a normal state where the failure detector 12i does not operate, the cameras 11c and 12f and the modulators 11d and 12g do not operate, and therefore the storage devices 11g and 12h do not operate.

On the other hand, when some abnormality occurs in the elevator car 12a and the passenger inside operates the intercom 12b, the terminal control device 12c connects the intercom 12b and the intercom 11a on the monitoring station 11 side by the telephone line 13 (Fig. Step S1) in the flowchart of FIG.

Therefore, when a technician who is packed in the monitoring station 11 uses the intercom 11a to give a question or an instruction to the intercom 12b on the monitored station 12 side, the intercom 12b responds to the passenger in the car 12a. For example, the failure recovery processing is performed in the normal state (step S3). In addition, the cameras 11c and 12f are activated, the video signal of the face of the technician of the monitoring station 11 is modulated by the modulator 11d, and is periodically taken in and stored in the storage device 11g, and is monitored via the telephone line 13. It is transmitted to the terminal control device 12c on the station 12 side, demodulated by the demodulator 12d, displayed on the display device 12e, and made visible to passengers in the car 12a.

At the same time, the image in the car 12a is photographed by the camera 12f, modulated by the modulator 12g and periodically fetched and stored in the storage device 12h.

Calls can be made through 1a and 12b, and the technician can grasp the condition inside the elevator car and give accurate questions and instructions, while the passengers inside the elevator car 12a can look at the face of the technician. Even if they are trapped in the car, they can alleviate their anxiety and be able to respond calmly, which makes it possible to improve the work efficiency of fault recovery.

However, when there is no response from the passenger in the car 12a (step S1), the failure detector 12i
Has issued a failure detection signal (step S2), the terminal control device 12c receives this signal, and the terminal control device 1
After the time set by the timer installed in 2c,
The terminal control device 12c activates the intercom 12a (step S3), the camera 12f in the car 12a starts to operate, and a picture of the inside of the car 12a is photographed, and its video signal is transmitted to the telephone line 13 as in the above case. Via monitoring station 11
Then, it is displayed on the display device 11e so that the engineer can see the inside of the car.

By doing so, even if the passenger cannot operate the intercom himself due to a sudden illness or the like, the technician on the monitoring station 11 side can take appropriate action by looking at the inside of the car. Can respond.

The present invention is not limited to the above-described embodiment, and in the above-mentioned embodiment, a still image by a camera, which has been put into practical use in recent years, is periodically fetched and sent to the other party through a telephone line. Although the transmission method is used, instead of this, the video signal captured by the camera may be directly transmitted as a moving image to the control device or the terminal control device of the other party and displayed on the display device.

Furthermore, if a digital line is used as the telephone line, the audio signal and the video signal may be transmitted independently and the transmission amount may be controlled.

Further, in the above embodiment, the elevator car 12a is provided with the failure detector 12i, and if the failure detector 12i operates, the camera station 12f of the camera 12f can operate from the monitoring station 11 side even if the intercom 12a is not operated. The captured video signal is taken out and displayed on the display device 11e, and the car 12a
By grasping the inside of the car, we have devised a safety measure even for people who have fallen in the car. However, if simplification of control is desired, this failure detector 12i is abolished and the monitoring station It is also possible to have a configuration in which the video signal captured by the camera of the other party can be displayed on the display device of its own between the monitor 11 and the monitored station 12.
