Description

The present invention relates to a monitoring system that monitors a remote location or the like, and more particularly to a monitoring system that can reliably acquire an image even when a line is disconnected or a power failure occurs, and can further improve convenience.

[Explanation of prior art]
Conventionally, surveillance cameras are installed in each of a plurality of surveillance areas, images taken by each surveillance camera are transmitted to a surveillance center via a transmission line, and an image sent from each surveillance camera is displayed on the monitor at the surveillance center. There is a surveillance camera system that monitors crimes, accidents, disasters, etc.

In surveillance systems that monitor dams, etc., surveillance cameras are often far from the monitoring room or monitoring post (management post), and in the event of a disaster such as an earthquake or heavy rain, the line transmitted from a remote location is disconnected or the power line is disconnected. Remote monitoring may not be continued due to disconnection, etc.

If the transmission line from the camera control device that controls the surveillance camera to the relay device is disconnected, the video will not be transmitted to the monitoring post, so not only monitoring but also video recording at the management post will not be possible, and the line will be restored even after the line is restored. It is not possible to acquire the video during the period when it was disconnected.

Further, when the power line is cut off, the surveillance camera can receive power from the uninterruptible power supply, but cannot take a picture for a long time.
Furthermore, in the event of an emergency such as a disaster, it is often necessary to create a report on the disaster situation, and the work of capturing the image to be referred to and creating the report is complicated.

[Operation when an earthquake occurs: Figures 1 to 3]
Next, the operation when an earthquake occurs will be described with reference to FIGS. 1 to 3.
When the camera control device 12 of the on-site system detects the occurrence of an earthquake by the signal from the seismograph 18, the camera 11 causes the camera 11 to perform an extraordinary inspection and shooting.
Specifically, when the camera control device 12 detects the occurrence of an earthquake, the camera control device 12 refers to the camera 11 according to a program for temporary inspection and shooting at the time of an earthquake, which is stored in advance, for example, 30 minutes after the occurrence of the earthquake. The camera 11 is made to take a picture more frequently than the normal schedule, such as after a minute, after an hour, after two hours, and so on.
In addition, the reason why the first shooting is set to 3 minutes after the occurrence of the earthquake is that it is assumed that the shaking at the time of the occurrence of the earthquake will be calmed down to some extent and the shooting will be possible.

The camera 11 cyclically shoots a plurality of preset points according to the instruction, and outputs the shot image of the dam to the camera control device 12.
Then, the camera control device 12 applies super-resolution compression processing to the video, and if the transmission line 10 and the self-employed line 200 are not disconnected, the camera control device 12 transmits the video data to the recorder 15 and the management office side system 300. To do.

It is output to the PC 34 and the large monitor 35.
At that time, the operation control PC may read the image before the earthquake (or the image corresponding to a plurality of points taken after the earthquake) from the control management server 39 and display the images before and after the earthquake side by side.

In the management office side system 300, when the staff determines that the situation is dangerous based on the seismic intensity information and images, it assumes that there is a person near the dam and calls for evacuation using the loudspeaker microphone 38. ..
The voice data input by the loudspeaker microphone 38 is received by the camera control device 12 of the site side system 100 via the self-employed line 200 and the transmission line 10, and is output as voice from the loudspeaker 16.

In this way, the operation at the time of the occurrence of an earthquake is performed, and images are taken frequently according to the passage of time so that the influence of the earthquake is not overlooked and can be useful for analysis.
In particular, in the system 300 on the management office side, the large monitor 35 and the display unit 36 display the image before the earthquake and the image received after the earthquake side by side, which are stored in the management control server 39, to cause an earthquake. Changes can be displayed in an easy-to-understand manner, which is useful for early detection of abnormalities.

[Operation when the transmission line 10 is disconnected: FIGS. 1 and 2]
Next, the operation when the transmission line 10 is disconnected due to an earthquake, heavy rain, or the like will be described with reference to FIGS. 1 and 2.

FIG. 6 shows a screen for creating an auxiliary paper attached to an earthquake occurrence report, and images before the occurrence of the earthquake and images immediately after the occurrence of the earthquake are arranged side by side at a plurality of points.
For example, when an instruction to create a report is input by the operation control PC 34 and a dam name, an earthquake occurrence date and time, and a point are input, the information is attached to the control management server 39 to request an image for control management. Based on the request, the server 39 reads out the images of the relevant points before and after the earthquake occurrence date and time from the accumulated images and outputs them to the operation control PC 34, and the operation control PC determines the data of the auxiliary paper. It is realized by capturing the image at the position and creating the electronic data of the auxiliary paper.

In the example of FIG. 6, the images of the embankment camera, the water-repellent wall camera, and the floodway camera are laid out side by side before and after the occurrence of the earthquake. In addition, next to the image, there is also a column for entering the situation by handwriting or the like, which can be written after printing.
This makes it easier to compare the state of each point before and after the earthquake, makes it easier to understand even if there is an abnormality such as damage, makes it easier to recognize the situation, and enables quick response. ..

The data of the electronic report and the auxiliary paper are transmitted from the information sharing server 41 to the upper monitoring organization, the head office, etc. via the intranet line 400 as needed, and similarly, the administrator or the person in charge via the public line 500.
