Quasi-realtime forest fire monitoring system based on small aircraft

Abstract

The invention is concerned with monitor system for forest fire, especially real time and dynamic monitor system and method based on mini-type of aerocraft. The system is different with conventional remote sensing equipment to gather data, while it will parse and adjudge data at real time and feedback to data gather equipment. The mini-type of aerocraft will offer especial monitor to object, such as forest fire. The system will enhance the efficiency to monitor and reduce the rate of misinformation of fire. The misinformation relates to no alarm with fire and alarm without fire. It will reduce the alarm periods of fire compare to conventional non-dynamic remote sensing exploration.

Description

Technical field [0001] The invention relates to a forest fire monitoring system, in particular to a quasi-real-time dynamic monitoring system based on a small aircraft and a realization method. Background technique [0002] Forest is an important natural resource, which is of great significance to nature, economy and earth ecology. The protection of forest resources, especially the prevention and control of forest fires, is an important part of environmental protection. With the strengthening of the greenhouse effect and global warming, forest fires are becoming more and more frequent. In order to achieve effective control of forest fires, rapid monitoring of forest fires has become a necessary premise. [0003] In view of the vast forest area and the inaccessible characteristics of some areas, there are many ways to realize forest fire monitoring. For example, using satellite imagery systems, we can provide images of the ground surface to determine whether there is a fir...

Problems solved by technology

However, the satellite system has the following weaknesses: (1) Interval in time: At present, fixed-orbit satellites do not provide high-definition surface image services, and the use of satellite systems around the earth usually circles once or several times a day. The interval is too long, and the time cannot be adjusted independently

(2) Geographic limitations: The flight path of the satellite is determined, and it is impossible to make specific adjustments according to the special circumstances that may occur in forest fires

(3) Orbital height: It is greatly affected by the cloud layer, which leads to a large error in judging the fire from the image

[0004] Another way to detect forest fires in the air is to learn from weather balloons, and use balloons to carry various fire detection sensor devices for monitoring, but balloons are more difficult to recover

[0005] At present, it is difficult for the aerial monitoring system to realize real-time monitoring in a complete sense. They all sample and monitor certain areas under certain time periods and intervals.

To achieve real-time monitoring, it is necessary to place distributed sensors on the forest floor. The quantity requirements and the technical requirements for information transmission make the total cost of this system very expensive, and it is difficult to realize it in a short period of time.
