The present invention relates to a forest fire monitoring system, and monitors the monitoring target mountain area (1) with a panoramic omnidirectional image (20), by selecting a concentrated monitoring area from the omnidirectional image (20), the detailed main monitoring PTZ image (30) And a mountain in a blind area that cannot be monitored by the omnidirectional image 20 is related to a forest fire monitoring system that monitors the secondary monitoring PTZ image 50 captured in detail by the auxiliary monitoring apparatus 200.

Forest fire monitoring systems have been proposed in various ways to detect fires early and fire alarms by using surveillance cameras for super fire extinguishing when forest fires occur in mountainous areas. In general, the surveillance camera installed on the mountaintop rotates 360 ° and transmits the captured image to the situation room, and the situation room monitors the mountain area by monitoring the received image. In addition, there was also a system for automatically detecting abnormal signs by comparing the image captured during the first rotation of the surveillance camera with the image captured during the second rotation.

However, since the surveillance camera rotates 360 ° as described above takes a long time to rotate once, there is a problem that can not be detected quickly in response to the time when the fire is ignited. In addition, since the images before and after the images are to be compared with each other according to the respective imaging angles, the data to be processed is enormous. Therefore, it is necessary to have a system capable of taking time delays or processing data faster.

In order to solve the above problems, Patent Registration No. 0452118 'Integrated environmental monitoring system', the monitoring device is composed of a main monitoring device and a plurality of auxiliary monitoring device, the primary monitoring device when the auxiliary monitoring device detects abnormal signs primarily The site where the abnormality is detected is closely monitored to determine whether the abnormality is a wildfire. However, in the above method, if the main monitoring device is not in operation, a forest fire monitoring system cannot be implemented, and the main monitoring device and the auxiliary monitoring device have a burden of having to compare and discriminate the captured front and rear image data. There is a problem that rapid forest fire monitoring is not possible due to the turn time.

As another conventional technique, a method of tracking the location of a wildfire occurrence, a method of accurately determining whether a wildfire has occurred in real time, a method using geographic information, and a method of using meteorological information are disclosed in Patent Registration No. 0227648, Patent Registration No. 002757, Patent Patent No. 0290600, Patent No. 0452118, Patent No. 0615672, and Utility Model Registration No. 0360332. However, there is a problem in that it is difficult to maintain due to the remaining trouble of the surveillance camera in actual application.

In addition, since the methods described above need to monitor a large area sequentially according to a preset imaging angle depending on the rotating surveillance camera, it is not possible to collectively monitor the mountain region to be monitored.

Accordingly, an object of the present invention is to provide a forest fire monitoring system for monitoring the mountain region to be monitored collectively.

Another object of the present invention is to provide a forest fire monitoring system for quickly detecting when a forest fire occurs.

Still another object of the present invention is to provide a forest fire monitoring system capable of monitoring the forest fire at all times without the trouble of the monitoring device.
