Embodiment Construction

[0044] The invention is a forest fire early warning system based on an uncooled infrared temperature detector. Aiming at the shortcomings of the unrefrigerated infrared temperature detector in the early detection of forest fires in a large space range, it provides a system that has been verified by experiments. A technical solution that can greatly reduce the false alarm rate and false alarm rate of forest fires can solve the problem of difficulty in determining the alarm threshold due to the uncertainty of detection distance, atmospheric transmittance, and atmospheric humidity, thereby effectively The false alarm rate and the false alarm rate are reduced, and the non-forest fire-like heat radiation can be correctly identified to reduce the false alarm rate.

[0045] Before the present invention summarizes the technical scheme of the present invention, some nouns and terms involved in the present invention are described as follows:

[0046] A. Uncooled infrared temperature det...

Abstract

The invention relates to a forest fire early-warning system based on a non-refrigerant infrared temperature detector. The system comprises at least one non-refrigerant infrared temperature detector, a network and an alarm server, wherein the non-refrigerant infrared temperature detector and the alarm server are connected with the network through respective network communication transmission equipment respectively. By the forest fire early-warning system, the problem of difficulty in determination of alarm threshold values caused by non-determinacy of detection distances, atmosphere transmittance and atmosphere humidity is solved, and then a false alarm rate and a false negative rate are effectively reduced.

Description

technical field [0001] The invention relates to a forest fire early warning system, in particular to a forest fire early warning system based on an unrefrigerated infrared temperature detector. Background technique [0002] my country is a country with low forest coverage but many forest fires. In recent years, with the strengthening of environmental protection awareness and resource protection awareness and the advancement of science and technology, passive fire prevention based on fire fighting is changing to active fire prevention based on early warning. Especially driven by information technology, aerospace and other technologies, my country's forest fire prevention has made great progress in monitoring and early warning, and is changing from focusing on manual prevention to establishing an unattended automatic early warning system. The basic policy of forest fire prevention of "fight early, small, and hard" was determined. [0003] Since the fire is greatly affected by...
