FIG. 5 is a view for explaining the division display of the means, and FIG. 5 is a view for explaining an enlarged display of the display means of the gas station monitoring apparatus according to the embodiment of the present invention.

In these figures, a gas station monitoring apparatus 10 according to the present embodiment includes a plurality of cameras 12 for picking up an image of a weighing machine 11 and its surroundings provided at various points in a station of a gas station. 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 a plurality of display units provided at various locations in the refueling station premises. A plurality of microphones 16; an accident judging means 17 for judging the presence or absence of an accident based on sounds collected by these microphones 16 and outputting an accident signal when an accident occurs; Recording means 18 for recording the video data from the camera stored in the means 14, an alarm 19 for issuing an alarm by an accident signal, and an alarm signal for notifying a remote location of the accident signal. Composed of a modem 20, 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. It is directed to image the corresponding weighing machine 11 and its surroundings.

The plurality of microphones 16 (16A, 16A)
B, 16C, 16D) are arranged, for example, one at a plurality of locations (four locations) in the vicinity of the camera 12, and each has a directivity such that sounds generated within a certain angular range can be collected. And is directed to the weighing machine 11 and its periphery.

The control means 13 and the storage means 14
And the accident determining means 17 is provided in the office 2 provided on the site.
1 is realized by a computer 22 disposed in the inside of the PC 1 or the like. The control means 13 is a part which receives the video data sent from each of the plurality of cameras 12, switches over the video data at regular intervals, and sequentially takes in the video data repeatedly. That is, the control means 13 is, for example,
After capturing the video data of the cameras 12B, 12C, and 12D sequentially from the camera 12A at regular intervals,
Returning to the camera 12A again, the operation of capturing video data is repeated in the same manner. The storage means 14 stores the control means 13
Are sequentially stored from the first storage area, and when the data reaches the last storage area, the video data is returned to the first storage area and updated and stored. This is realized by a semiconductor memory or the like. Therefore, as shown schematically in FIG. 3, the storage means 14 stores the video data of each of the cameras 12A to 12D in order, and is repeated for a fixed time determined by the capacity. The accident judging means 17 is a part for judging the presence or absence of an accident based on the sound collected by the microphone 16 and outputting an accident signal when it is judged that there is an accident. In the accident judgment by the accident judging means 17, for example, it is judged that there is an accident when a loud noise generated by a collision or contact of the car or a loud voice emitted when the worker witnesses the accident is detected.

The display means 15 is, for example, a display connected to the computer 22. 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, and displays the divided data in response to an accident signal. 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.
The video data (A, B, C, D) of the cameras 12A, 12B, 12C, 12D is divided and displayed on the same screen, and when an accident occurs, as shown in FIG. The image data (A) of 12A is enlarged and displayed.

The recording means 18 is, for example, a video recorder, and when receiving an accident signal from the accident judging means 17, records the video data corresponding to the accident stored in the storage means 14. For example, recording means 1
7, when the accident judging means 17 judges that there is an accident between the video data An + 9 and An + 10 and outputs an accident signal, as shown in FIG. +1
,..., An + 9 and the video data An + 10 after the occurrence of the accident are recorded on a tape by a video recorder.

The annunciator 19 is, for example, a siren that generates sound by an accident signal, and is attached to a wall of the office 21 or the like. The modem 20 is a modem for transmitting an accident signal to a headquarters, a fire department, or a police department via a telephone line. The weighing machine 11 is connected so as to stop upon receiving an accident signal from the accident judging means 17.

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 accident determination means 17 determines the presence or absence of an accident from the sound collected by the microphone 16, and determines that there is an accident. Outputs an accident signal. When this accident signal is output, the microphone 16 that has detected the accident
Corresponding camera 1 that is imaging the location where is pointed
2 is recorded on the recording means 17 and the display means 1
In 5, the video data of the accident is enlarged and displayed, and at the same time, the weighing machine 11 is stopped, and the alarm 19, which is the alarm means, issues an alarm or is notified via the modem 20. Therefore, the accident is reliably detected early, and the weighing machine 11 is stopped promptly.
By notifying by the annunciator 19 and notifying the headquarters, fire department, or police station via the modem 20, the spread of the accident can be prevented. In addition, the state of the accident 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 is described in which the weighing machine 11 and the four cameras 12 and the microphone 16 are arranged on the gas station premises and around the gas station. It is only necessary that a plurality of cameras for capturing images and a plurality of microphones for collecting sound be 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 accident determining means 17 is at least
Any device may be used as long as it determines the presence or absence of an accident based on the magnitude of the sound collected by the microphone 16 and the impact sound peculiar to a collision or the like, and outputs an accident signal when it is determined that there is an accident.

[0017]

As described above, in the gas station monitoring apparatus of the present invention, the accident judging means judges the presence or absence of an accident from the sound collected by the microphone, and outputs an accident signal when it is judged that there is an accident. This makes it possible to accurately detect the occurrence of an accident and to notify an early stage.
