In these figures, a gas station monitoring device 10 of the present embodiment comprises a plurality of cameras 12 for picking up images of a weighing machine 11 and its surroundings provided at various places within a gas station, and from these cameras 12. Control means 13 for sequentially switching in and capturing the image data, storage means 14 for sequentially storing the image data, display means 15 for displaying the image data in one screen, and vibrations provided in each of the weighing machines 11 respectively. And the storage means 14 when the seismic sensor 16 receives a stop signal for detecting vibration.
The recording means 17 for recording the video data from the camera 12 stored in 1., the alarm 18 for issuing an alarm by a stop signal, the modem 19 for notifying a remote place based on the stop signal, and the like.

The plurality of cameras 12 (12A, 12A)
B, 12C, 12D) are arranged, for example, one at each of a plurality of places (four places) around the site, and each of them has a predetermined monitoring angle and is placed in a substantially central portion of the site. Corresponding weighing machine 11 (11A, 11B, 11C, 11
D) and its surroundings.

The control means 13 and the storage means 14
Is realized by a computer 21 arranged in an office 20 or the like provided on the premises. Control means 1
Reference numeral 3 denotes a portion that receives video data sent from each of the plurality of cameras 12, switches the video data at regular intervals, and sequentially captures the video data. That is, the control means 13 is, for example, the camera 12 at regular time intervals.
Camera 12B, camera 12C, camera 12D in order from A
After capturing the image data of, the process returns to the camera 12A again and the operation of capturing the image data is repeated. The storage means 14 stores the video data sequentially sent from the control means 13 in order from the first storage area, and when it reaches the last storage area, returns to the first storage area and updates and stores it. Yes, for example, it is realized by a semiconductor memory or the like having a predetermined capacity. Therefore, this storage means 14 is provided for each camera 1 as schematically shown in FIG.
The video data of 2A to 12D are stored in order and repeated for a fixed time determined by the capacity.

The display means 15 is, for example, a display connected to the computer 21, and normally displays the video data of a plurality of cameras 12 stored in the storage means 14 on the same screen and displays them by a stop signal. The image data in which the accident occurred is enlarged and displayed. For example, the display means 15 normally has the following structure as shown in FIG.
When the image data (A, B, C, D) of the cameras 12A, 12B, 12C, and 12D are divided and displayed on the same screen, and the seismoscope 16A receives a stop signal that detects vibration, FIG.
As shown in, the image data (A) of the camera 12A that is capturing an image of the weighing machine 12A that has detected the vibration is enlarged and displayed.

The seismic sensor 16 (16A, 16B, 16)
C and 16D are the weighing machines 11 (11A and 11D, respectively).
B, 11C, 11D), and when a vibration is detected, it is determined that an accident has occurred and a stop signal is output. Such vibration detection is realized by, for example, a structure in which a switch is closed by a mechanical operation when a vibration having a predetermined strength is generated.

The recording means 17 is, for example, a video recorder, and when the stop signal from the corresponding seismic sensor 16 is received, it records the video data corresponding to the accident stored in the storage means 14. is there. For example, when the seismoscope 16A detects vibration between the image data An + 9 and An + 10 and outputs a stop signal, the recording means 17 outputs the image data before the accident, as shown in FIG. An, An + 1, ...,
An + 9 and video data An + 10 after the accident occurred are recorded on tape with a video recorder.

The alarm device 18 is, for example, a siren that produces a sound by a stop signal, and is attached to the wall of the office 20 or the like. The modem 19 is a modulation / demodulation device for transmitting a stop signal to the headquarters, fire department, or police station via a telephone line. Further, the weighing machine 11 is connected so as to stop upon receiving a stop signal from the seismic sensor 16.

In the gas station monitoring device 10 having the above-mentioned structure, the video data of the plurality of cameras 12 arranged at various places of the gas station are sequentially switched by the control means 13 at regular intervals, and the video data is taken. Storage means 1
4, the video data is divided and displayed on the same screen by the display means 15 at the same time, and the seismoscope 16 detects vibration and outputs a stop signal when it is judged that an accident has occurred. When this stop signal is output, the corresponding weighing machine 11 is stopped, and the video data of the corresponding camera 12 capturing the image of the weighing machine 11 that has detected the vibration is recorded by the recording means 17.
The corresponding video data is enlarged and displayed on the display means 15, and at the same time, the alarm device 18 which is the notification device issues an alarm or is notified via the modem 19. Therefore,
The worker at the office 20 can quickly and surely know the accident by the display of the display means 15, and immediately stop the weighing machine 11, notify the alarm 18 and notify the headquarters or the fire department via the modem 19. By calling the police station,
It is possible to prevent the accident from spreading. The state of the accident at this time is enlarged and displayed on the display unit 15 and the before and after the accident is recorded on the recording unit 17, so that it is possible to easily confirm the accident and deal with it later.

In the above embodiment, an example in which the weighing machine 11 and the four cameras 12 and the seismic sensors 16 are arranged toward the periphery of the gas station has been described, but it is necessary to monitor at least the gas station site. It suffices if a plurality of cameras and a plurality of seismic sensors for picking up images of different weighing machines are arranged. Further, the storage means 14 may be one that sequentially and repeatedly stores the video data of a plurality of cameras, and the storage capacity thereof is also arbitrarily determined by the number of video data, the repetition time, and the like. Furthermore, the vibration-sensing device 16 may be provided at least in the weighing machine 11 so as to detect a vibration of a predetermined strength due to a collision or a contact of an automobile and output a stop signal.
