DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator car image recording apparatus capable of recording a situation inside a car by using a television camera so as to be useful for crime prevention or the like.

[0002]

2. Description of the Related Art The prior art in which a television camera is installed in a car of an elevator so that the situation in the car can be grasped is disclosed in Japanese Patent Application Laid-Open No. 59-98881 and Japanese Utility Model Application Laid-Open No. 52-1.
No. 33468, Japanese Utility Model Application Laid-Open No. 4-40080, and the like.

FIG. 2 is an explanatory view showing the basic configuration of these prior arts. Reference numeral 1 denotes a machine room, 2 denotes a control panel installed in the machine room 1, 3 denotes a hoistway, and 4 denotes Hoistway 3
5 is a counterweight which is connected to the car 4 in a hanging manner, 6 is a tail cord wired from the control panel 2 through the hoistway 3 to the car 4, and 7 is A television camera 8 installed in the car 4, an image line 8 wired from the control panel 2 through the building to an external management room 9 and the like, a VTR 10, a monitor 11.

As shown in FIG. 2, conventionally, electric wires are supplied from a control panel 2 in a machine room 1 to a television camera 7 installed in a car 4 by using a tail cord 6, and the television camera 7 takes a picture. The transmitted image is transmitted to the outside management room 9 and the like via the tail cord 6, the control panel 2, the image line 8 and the like, so that the VTR 10 and the monitor 11 installed there are used to transmit the image to the inside of the car 4. It is configured such that the recording of the situation and the constant monitoring can be performed.

[0005]

The above-mentioned prior art has been proposed in order to respond to the growing need for crime prevention to prevent crime in the elevator car. In order to reduce the number of buildings, there are many buildings without managers, and it is becoming difficult to constantly monitor the inside of the car. In order to cope with such a situation, a countermeasure without the use of a manager has been implemented, such as using a time-lapse VTR capable of recording video images of a car at predetermined minute time intervals.

However, if the television camera in the car is damaged due to mischief, or if a crime occurs when the VTR for recording video cannot record video due to equipment failure, video recording becomes impossible. There has been a problem that the function originally exhibited by the in-car video recording device is abandoned.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned deficiencies of the prior art, and has as its object the purpose of quickly transmitting a failure to another system when a television camera or a VTR fails, and promptly indicating a state where video recording cannot be performed. It is another object of the present invention to provide an elevator car video recording apparatus characterized by solving the above problem.

[0008]

SUMMARY OF THE INVENTION The object of the present invention is to provide an elevator car equipped with a television camera for photographing the situation inside the car, and for recording images taken by the television camera. A video recording device in an elevator car provided with a VTR, comprising: a failure detection device for detecting that the television camera or the VTR has failed; if the failure detection device detects a failure, the other system fails. This can be achieved by providing a failure transmission device that transmits

[0009] Here, it is desirable that another system for transmitting the failure information, such as a monitoring center of an elevator maintenance company, constantly monitors the status of the elevator.

As described above, if the failure of the television camera and the VTR is detected and transmitted to another system, a quick failure can be dealt with, and the video recording device in the elevator car cannot record the video. Can be eliminated quickly.

[0011]

Embodiments of the present invention will be described below. FIG. 1 is a functional block diagram showing an embodiment of an elevator car video recording apparatus according to the present invention, and FIG. 2 shows the same or corresponding parts by the same reference numerals. In the figure, 12
Denotes an image input device for receiving an image of the television camera 7, 13
Denotes a video recording device that records a signal received by the video input device 12. Reference numeral 14 denotes a failure detection device that detects that the video input device and the video recording device have failed. Reference numeral 15 denotes a failure transmission device that transmits to the failure reception system 16 that the failure detection device 14 has detected a failure.

Next, the operation of this embodiment will be described. The image from the television camera 7 is normally input to the image input device 12
Is recorded on the video recording device 13 via the. Here, when the television camera 7 is damaged due to mischief or the like, the video is not input to the video input device 12. Failure detection device 1
4 constantly monitors whether an image is input to the image input device 12, and when there is an abnormality in the image input as described above,
System 1 for receiving a failure via failure transmission device 15
6 is notified of the failure of the television camera 7. Similarly, when the video recording device 13 cannot perform normal recording due to a cause such as dew condensation, the failure detection device 14 notifies the system 16 that receives the failure via the failure transmission device 15 of the failure of the video recording device 13. TV camera 7 or video recording device 13
The failure receiving system that has received the information on the failure of the above will immediately dispatch a maintenance worker to take measures against the failure.

With the above-described configuration, a failure of the television camera and the VTR can be detected and transmitted to another system, thereby promptly coping with the failure. It can be resolved quickly.

[0014]

As described above, the elevator car video recording apparatus according to the present invention comprises a television camera and a VTR.
By detecting the failure and transmitting the failure to another system, it is possible to quickly respond to the failure, and to achieve an excellent effect that the state in which video recording in the elevator car cannot be recorded can be quickly eliminated.
