In these figures, a gas station monitoring apparatus 10 according to the present embodiment includes a weighing machine 11 provided at various points on a gas station site and a plurality of cameras 12 for imaging the periphery thereof. Control means 13 for sequentially switching and capturing the video data, storage means 14 for sequentially storing the video data, display means 15 for dividing and displaying the video data on one screen, and detecting vibration provided on each of the weighing machines 11 respectively. And a storage means 14 when receiving a stop signal indicating that the vibration sensor 16 has detected vibration.
Recording means 17 for recording the video data from the camera 12 stored in the storage unit, an alarm 18 for issuing an alarm by a stop signal, a modem 19 for notifying a remote location based on the stop signal, and the like.

The plurality of cameras 12 (12A, 12A)
B, 12C, and 12D) are disposed, for example, one at a plurality of locations (four locations) around the site, and each of them has a predetermined monitoring angle and is disposed at a substantially central portion of the site. The 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 and switches over the video data at predetermined time intervals to sequentially capture video data. That is, for example, the control unit 13 controls the camera 12 at regular intervals.
Cameras 12B, 12C, and 12D in order from A
After capturing the video data, the operation of returning to the camera 12A again and capturing the video data in the same manner 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 reaching the last storage area, returns to the first storage area to update and store. Yes, and is realized by, for example, a semiconductor memory having a predetermined capacity. Therefore, this storage means 14 stores each camera 1 as schematically shown in FIG.
The video data of 2A to 12D is stored in order, and is repeated for a fixed time determined by the capacity.

The display means 15 is, for example, a display connected to the computer 21. Usually, the display means 15 divides and displays the video data of the plurality of cameras 12 stored in the storage means 14 on the same screen. The video data in which the accident has occurred is enlarged and displayed. For example, the display means 15 usually includes, as shown in FIG.
When the video data (A, B, C, and D) of the cameras 12A, 12B, 12C, and 12D are divided and displayed on the same screen, and the seismic sensor 16A receives a stop signal that has detected vibration, FIG.
As shown in (2), the video data (A) of the camera 12A capturing the image of the weighing machine 12A that has detected the vibration is displayed in an enlarged manner.

The seismic sensor 16 (16A, 16B, 16)
C, 16D) are respectively weighing machines 11 (11A, 11D).
B, 11C, and 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 vibration of a predetermined intensity occurs.

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

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

In the refueling station monitoring apparatus 10 having the above-described configuration, the video data of the plurality of cameras 12 arranged at various locations on the refueling station site are sequentially switched and taken in at regular intervals by the control means 13, and the video data is obtained. Storage means 1
4 are sequentially stored, and at the same time, the video data is divided and displayed on the same screen by the display means 15, and the seismic sensor 16 detects vibration and outputs a stop signal when it is determined that an accident has occurred. When the stop signal is output, the corresponding weighing machine 11 stops, and the video data of the corresponding camera 12 capturing an image of the weighing machine 11 that has detected the vibration is recorded by the recording unit 17.
The corresponding video data is enlarged and displayed on the display means 15, and at the same time, the alarm 18 serving as the alarm means issues an alarm or is notified via the modem 19. Therefore,
The worker in the office 20 can surely know the accident at an early stage by the display on the display means 15, and immediately stops the weighing machine 11, informs by the annunciator 18, and via the modem 19 to the headquarters or fire department. By calling the police station,
Accidents can be prevented from spreading. The state of the accident at this time is enlarged and displayed on the display means 15 and the recording means 17 is recorded before and after the accident, so that it is possible to easily confirm the accident and deal with it later.

In the above embodiment, an example has been described in which the weighing machine 11 and the four cameras 12 and the seismic sensor 16 are arranged on the premises of the gas station, but it is necessary to monitor at least the premises of the gas station. It suffices if a plurality of cameras and a plurality of seismic devices for imaging a weighing machine are arranged. The storage means 14 only needs to store video data of a plurality of cameras sequentially and repeatedly, and its storage capacity is arbitrarily determined according to the number of video data, the repetition time, and the like. Further, the seismic device 16 may be any device that is provided at least in the weighing machine 11 and detects vibration of a predetermined strength due to collision or contact of the vehicle and outputs a stop signal.

[0017]

As described above, the gas station monitoring device of the present invention outputs a stop signal when the seismic devices provided in the weighing machines detect the vibration and determine that there is an accident. Accident occurrence can be accurately detected, and early notification can be made.
