Abstract

PROBLEM TO BE SOLVED: To rapidly dissolve a state of failing to record images by making the backup image recording device of an image recording device start photographing a state in a car at the time of detecting a failure by a failure detecting device for detecting the failure of the image recording device. SOLUTION: The image of a telecamera 7 is recorded in an image recording device 13 via an image input device 12 during normal operation. In the case of the generation of a state of failing to record images due to the break of a video tape in the image recording device 13 or an equipment failure caused by dew condensation or the like, a failure detecting device 15 is actuated to command a backup image recording device 14 to start image recording, and the image of the image input device 12 is recorded in the backup image recording device 14 by the operation of failure detecting device interlocking contacts 15A, 15B. Accordingly, even in the case of the failure of the image recording device 13, the state of failing to record images can be eliminated by photographing of the backup image recording device 14.

Description

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, power is conventionally 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 this, countermeasures for absence of a manager such as using a time lapse VTR capable of recording a video record of a car at predetermined minute time intervals have been implemented.

However, if a crime occurs when the video recording device that records video cannot record video due to equipment failure, video recording becomes impossible, and the functions originally provided by the video recording device in the car are abandoned. There was a problem of getting it.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described deficiencies of the prior art, and has as its object that, when a video recording device fails, a backup video recording device starts photographing the situation in a car, An object of the present invention is to provide an elevator car video recording apparatus characterized in that a state in which video recording cannot be performed is quickly eliminated.

[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. In the elevator car video recording device provided with the video recording device, a failure detection device that detects that the video recording device has failed, when the failure detection device detects a failure, backup of the video recording device This can be achieved by the video recording device for the start of photographing the situation in the car.

As described above, if the configuration is such that the failure of the video recording device is detected and the backup video recording device starts photographing the situation in the car, the video of the video recording device in the elevator car can be obtained. The state in which recording cannot be performed can be quickly eliminated.

[0010]

Embodiments of the present invention will be described below. FIG. 1 is a functional block diagram showing an embodiment of an elevator car image recording apparatus according to the present invention, wherein the same reference numerals as those in FIG. 2 denote the same or corresponding parts. In the figure, reference numeral 1
Reference numeral 2 denotes a video input device for receiving a video of the television camera 7, reference numeral 13 denotes a video recording device for recording a signal received by the video input device 12, and reference numeral 14 denotes a backup video recording device for the video input device 12. Reference numeral 15 denotes the video recording device 1
3 shows a failure detection device for detecting that a failure has occurred. Reference numerals 15A and 15B indicate contacts that are linked to the operation of the failure detection device 15.

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 video tape in the video recording device 13 is cut or the video cannot be recorded due to a device failure such as dew condensation, the failure detection device 15 operates and instructs the backup video recording device 14 to start video recording. 15A, 15
When the contacts of B operate, the video input device 12
Is recorded in the backup video recording device 14.

With the above arrangement, the failure of the video recording device is detected, the backup video recording device starts photographing the situation in the car, and the state in which the video recording cannot be performed can be quickly eliminated. .

[0013]

As described above, the elevator car video recording device according to the present invention detects a failure of the video recording device, and the backup video recording device starts photographing the situation in the car, An excellent effect of quickly eliminating a state in which video recording cannot be performed is achieved.
