DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring device in an elevator car used for preventing various crimes in the elevator.

[0002]

2. Description of the Related Art A conventional monitoring device in an elevator car has, for example, a video camera installed in the elevator car and image data taken by the video camera provided in a monitoring room via a cable. It was configured to send and monitor to a general video recorder.

For example, as shown in a conventional example of Japanese Patent Application Laid-Open No. 11-16067, a time-lapse video recorder whose video recording density changes depending on the presence or absence of a person in a car detected by a human body detection sensor is mounted on a vehicle. It is configured to be attached to the outer periphery of a car, for example, on the outer surface of a ceiling plate, to record image data of a video camera, and to play back and check the recorded image data.

In Japanese Patent Application Laid-Open No. 11-16067, an image recording / reproducing section connected to a camera is provided outside a car, and a radio transmitting / receiving section connected to the image recording / reproducing section is controlled in the car. Provided on the panel, the wireless transmitting and receiving unit,
The document describes that wireless transmission is performed with a display control terminal brought into a car to reproduce and check image data captured by the camera.

[0005]

In the method of monitoring in the monitoring room, it is necessary to lay a cable between the video camera of the car and the video recorder in the monitoring room, which increases the size of the equipment and increases the cost.

[0006] The time-lapse video recorder is mounted on the outer peripheral wall of the ceiling of the car, and the image data of the video tape is reproduced and confirmed. A maintenance person moves a display monitor such as a display to the site (the ceiling of the car). It has to be brought in and connected to a time-lapse video recorder, which is very cumbersome, and requires a lot of time for installation and adjustment. .

There is also a disadvantage that recording cannot be performed while the video tape is being rewound. Further, the maintenance staff must work on the ceiling outer wall of the car, which poses a danger.

A system for providing a radio transmission / reception unit on a control panel in the car and reproducing and confirming image data by radio transmission with a display control terminal brought into the car is a transmission / reception for image signals. Means and signal processing means;
It is necessary to provide a transmission / reception unit and a signal processing unit for control signals, respectively, which greatly complicates the device configuration and increases the size.

[0009] Further, there is a disadvantage that a specially designed terminal must be used as a display control terminal.

The present invention has been made in view of the above points, and has as its object to quickly, easily and safely reproduce image data.
Confirmation work can be performed and the device configuration can be reduced in size.
Another object of the present invention is to provide a monitoring device in an elevator car, in which the reproduction and the checking operation can be performed by a terminal device such as a personal computer generally used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes an elevator car, and a camera device 2 is provided on an inner surface of a ceiling plate 1u. The camera device 2 includes a board 3 for mounting various components, a human body detection sensor 4, a video camera 5, and an infrared communication element 6 mounted on the board 3, and the video camera 5 and the infrared communication element 6
And a cover 7 that covers the

The cover 7 is made of a color and a material which do not hinder photographing of the video camera 5 and communication of the infrared communication element 6. The human body detection sensor 4 is a camera device 2
It is not limited to being integrally formed, and may be provided separately.

The camera device 2 is connected to a control recording device 10 via a connection line 8. This control recording device 10
Is installed on the outer peripheral wall of the car 1, for example, on the outer surface side of the ceiling plate 1 u, and the image recording unit 11 and the interface unit 12
And a control unit 13.

The image recording section 11 records the image data captured by the video camera 5, and is composed of, for example, a time-lapse VTR for recording at a predetermined minute time interval.

The interface section 12 interfaces with the camera device 2 and supplies power, for an image signal of a video camera, for a human body detection signal from the human body detection sensor 4, and for an infrared transmission / reception signal. It consists of each interface.

The control unit 13 remotely operates the image recording unit 11 or transmits an image recorded in the image recording unit 11 in response to a command from a terminal device described later transmitted through the infrared communication element 6. Various controls such as transferring data to the terminal device via the infrared communication element 6 are performed.

Reference numeral 20 denotes a car 1 in which a maintenance person is used to play and check image data picked up by the video camera 5.
It is a terminal device to be brought into the device, and is configured by a generally used personal computer, for example.

In the apparatus configured as described above, the image captured by the video camera 5 is always time-lapse VT
R (image recording unit 11). At this time, when the human body detection sensor 4 determines that no person is present in the car 1, when it is determined that the minute recording time of the time-lapse VTR is set to be long and the video recording density is low, the person is present. In this case, the minute recording time of the time-lapse VTR is set short, and the video recording density increases.

Next, when reproducing and checking the image data of the image recording section 11, a maintenance person brings the terminal device 20 into the car 1, issues a command through the infrared communication element 6, and performs control recording. The device 10 is remotely operated. Thus, the recorded image data can be transferred to the terminal device 20 via the infrared communication element 6 or the transferred image data can be displayed on the screen of the terminal device 20 for confirmation. .

The operation of reproducing and confirming the image data is performed by the car 1 if the communication range of the infrared communication element 6 is within.
Not only inside but also on each floor, elevator hall, etc. This eliminates the need for maintenance personnel to enter the car.

Further, the communication means of the present invention is not limited to the infrared communication element 6, and may be configured to be able to perform communication by another radio wave method, for example.

The image recording unit 11 is a time lapse VT
Not only R but also other disk-shaped recording media may be used.

[0024]

As described above, according to the present invention, the following excellent effects can be obtained. (1) It is not necessary to remove a video tape or bring a special video recorder (for example, a time-lapse VTR) when reproducing and checking image data. (2) The work of reproducing and checking the image data is extremely simplified, and the time for stopping the elevator for the work is shortened. (3) Dangerous work on the outer peripheral wall of the elevator car, for example, the ceiling, is not required. (4) The number of steps for installing the apparatus of the present invention is extremely small. In addition, the infrared communication element as a communication means,
Since it can be built in the video camera side as the imaging means, the device configuration can be downsized. (5) Since a general personal computer can be used as the terminal device used in the present invention, there is no need to develop dedicated hardware. (6) The reproduction and confirmation of the image data can be carried out not only in the car but also on each floor outside the car, in the elevator hall, etc. as long as the communication means is within the communicable range of the communication means.
This eliminates the need for maintenance personnel to enter the car. (7) When a disk-shaped recording medium is used as the recording medium of the control recording means, the life is longer than other media, for example, a video tape, and maintenance and inspection are facilitated.
