2. Description of the Related Art A conventional monitoring and recording apparatus in a moving space will be described with reference to FIG. FIG. 3 is a block diagram of a conventional surveillance and recording device, where 301 is a moving space, here an elevator, 302 is an image input device installed to monitor the inside of the moving space 301, here a camera, and 303 is a moving device. A sensor attached to a camera 302 that issues an alarm when a person is in the space 301, a storage device 304 for storing captured image data, and a camera device 305
And a data communication cable from the storage device 304 to the storage device 304.

[0003] A procedure for taking an image of the inside of the elevator 301 and storing the image data in the storage device 302 in the conventional moving space monitoring apparatus configured as described above will be described. The camera 302 moves inside the elevator 301 at certain intervals (constant recording) or when the sensor 303 recognizes that a person is inside the elevator 301 (alarm recording).
I am taking pictures. The captured image is stored in the storage device 304 through the communication cable 305.

[0004]

However, in the conventional apparatus installed in the elevator, the communication cable is connected to the elevator. Therefore, when the elevator moves up and down, the communication cable must be moved up and down together. Did not. At this time, the length of the communication cable is required at least for the distance the elevator moves. For this reason, in addition to the weight of the elevator body, the weight of the communication cable increases, and the elevator capacity is reduced by the increase.

It is an object of the present invention to provide a monitoring and recording apparatus which can be installed in a moving space without significantly increasing the weight of the moving space such as an elevator.

[0006]

According to the present invention, there is provided a monitoring and recording apparatus in a moving space, comprising: an image input device such as a camera installed in the moving space; and storage means for temporarily storing data from the image input device. Wireless transmission means for transmitting the data stored in the storage means to the outside of the moving space by wireless transmission, wireless receiving means installed at a reference position outside the moving space and receiving the data transmitted from the transmission means, Mass storage means for storing data.

According to the present invention, it is possible to install a monitoring and recording device in a moving space without significantly increasing the weight of the moving space such as an elevator.

(Embodiment 1) FIG. 1 is a configuration diagram of a monitoring storage device according to Embodiment 1 of the present invention. In FIG. 1, reference numeral 101 denotes an elevator as a moving space; 102, a camera installed in the elevator 101 to capture images in the elevator 101; 103, a camera installed near the camera 102 to detect the presence of a person in the elevator 101; A sensor 104 that issues an alarm signal when it is activated is installed in the elevator 101, a temporary storage device for temporarily storing data from the camera 102, and 105 is an elevator 1
01, a wireless transmitter for wirelessly transmitting data outside the elevator 101; 106, a wireless receiver installed at a reference position outside the elevator 101 (eg, the first floor in an elevator) to receive data from the wireless transmitter 105 , 107 are mass storage devices for storing data from the wireless receiver 106.

A procedure for storing a captured image in the large-capacity storage device 107 in the above configuration will be described. Camera 10
2 is installed so that the inside of the elevator 101 can be photographed and performs photographing at a preset time interval (constant recording), or the sensor 103 installed near the camera 102 has a person inside the elevator 101 When an alarm is issued upon detection of an alarm, an operation such as photographing (alarm recording) is performed.

The image data obtained from the camera 102 is stored in a temporary storage device 104 after adding time information and the like.

When the elevator 101 arrives at the first floor, which is a reference position, the wireless transmitter 105 transmits all the image data stored in the temporary storage device 104 to the wireless receiver 106 while the elevator 101 is moving. The wireless receiver 106 that has received the image data is stored in the mass storage device 107, and is taken out and used as needed.

As described above, the image data when the elevator is moving is stored in the temporary storage device, and is stored in the large-capacity storage device using the radio transceiver when the elevator comes to the reference position. Accordingly, it is possible to install the monitoring and recording device in the elevator without significantly increasing the weight of the elevator.

(Embodiment 2) FIG. 2 is a block diagram of a monitoring and recording apparatus according to Embodiment 2 of the present invention, and shows a monitoring and recording apparatus in a train which has not been conventionally installed.

In FIG. 2, reference numeral 201 denotes a train which is a moving space; 202, a camera which is installed in the train 201 to capture an image of the train 201; 203, which is installed near the camera 202; The sensor 204 that issues an alarm signal when detecting that

Reference numeral 206 denotes a wireless receiver that is installed at a reference position (station or the like in a train) outside the train 201 and receives data from the wireless transmitter 205, and 207 denotes a large-capacity storage device that stores data from the wireless receiver 206. .

A procedure for storing a captured image in the large-capacity storage device 207 in the above configuration will be described. Camera 20
2 is installed so that the inside of the train 201 can be photographed,
Shooting is performed at a preset time interval (constant recording), or shooting is performed when an alarm is issued when a sensor 203 installed near the camera 202 detects that a person is in the train 201 (alarm). Recording).

Image data obtained from the camera 202 is stored in a temporary storage device 204 after adding time information and the like. When the train 201 arrives at the station that is the reference position, the wireless transmitter 205 transmits the temporary storage device 2 while the train 201 is moving.
04 is stored in the wireless receiver 20.
6 is transmitted. Upon receiving the image data, the wireless receiver 206 stores the image data in the large-capacity storage device 207, and extracts and uses the image data as needed.

As described above, the image data when the train is moving is stored in the temporary storage device, and when the train reaches the reference position, the image data is stored in the large-capacity storage device using the radio transceiver. Thereby, it is possible to obtain an image of a moving train without using it. Further, since no radio waves are used, it is possible to avoid disturbance to the outside.

In the first and second embodiments, if a storage medium used for a large-capacity storage device is, for example, an optical disk capable of recording and reproduction, replacement, reuse (re-recording), and handling are easy. The performance of the monitoring and recording device can be effectively exhibited.
