Method and system for detecting forest fire

Abstract

The invention provides a method and a system for detecting forest fire. The system is composed of a forest monitoring point which comprises a heavy-duty digital tripod head 1, a thermal infrared imager 2, a visible light camera 3, a micro-meteorological station 4, embedded video processing equipment 5 and a communication bridge 6, and a command and control center which comprises a telemonitoring computer 7 and a communication bridge 8, wherein, the two communication bridges are communicated by a microwave wireless Tcp / IP network. The fire detection work is sequentially performed by the following six major steps: (1) field data acquisition, (2) image data processing, (3) fire recognition and analysis, (4) transmission of recognition results, (5) fire probability assessment and (6) automatic fire early warning. The method and the system combines video compression and decompression technology, thermal infrared image recognition and analysis technology, visible light color image recognition and analysis technology, embedded technology, wireless communication technology, remote sensing (RS) technology and 3D geographic information system technology to automatically recognize forest fire and analyze fire strategies, thus the method and the system are characterized by high detection probability of forest fire, low false alarm rate, no artificial participation, strong timeliness, highreliability, advanced technological means and wide market prospects.

Description

technical field [0001] The invention belongs to the technical field of fire safety detection, and in particular relates to a forest fire detection method and system. Background technique [0002] Forest fire is one of the major disasters in global forestry, which causes heavy loss of forestry resources and large-scale environmental pollution every year. Traditional forest fire monitoring mainly adopts manual observation, remote video monitoring and satellite remote sensing. [0003] The artificial lookout method is to set up lookout posts at the commanding heights, and the on-duty personnel are on duty 24 hours a day. Due to human negligence and negligence, many fires will not be detected early, delaying the fire fighting time, and causing serious consequences. [0004] The remote video monitoring method is to build a large number of video monitoring points in the forest area. The monitoring points are equipped with cameras, and the real-time images are transmitted to the m...

AI Technical Summary

Problems solved by technology

However, the thermal infrared video monitoring system does not solve the shortcomings of the visible light camera monitoring system that requires manual participation. It still needs manual judgment of forest fire danger with the naked eye, and both meteorological parameters that are important to the probability of fire occurrence cannot be effectively grasped in real time.

[0005] The method of satellite remote sensing is to detect forest fires after processing remote sensing photos, but satellites can only detect forest fires in a large area, and cannot detect forest fires in the early stage

[0006] In recent years, due to the lag in the development of forest fire detection technology, forest fires have occurred from time to time, causing huge economic losses
