Wide-area real-time mountain fire monitoring device for power grid based on multi-spectral thermal energy monitoring radar

Abstract

The invention discloses a wide-area real-time mountain fire monitoring device for a power grid based on a multi-spectral thermal energy monitoring radar, which includes a radar antenna device and a terminal industrial computer connected in communication with the radar antenna device. The radar antenna device includes a radar antenna, a dual-spectrum camera, a pitching Box, U-shaped support, base and wireless transmission module, the radar antenna is fixed to one end of the pitch box through the flange, the other end of the pitch box is suspended in the air, the dual-spectrum camera is fixed to the side of the radar antenna through the bracket, and the upper end of the U-shaped support The pitch gear bearings installed on the two side walls of the pitch box are rotationally connected to the middle of the pitch box, and the lower end of the U-shaped support is rotationally connected to the top of the base through the cross roller slewing gear bearings installed on the top of the base. The transmission module communicates with the camera IP box inside the pitch box. The invention has the advantages of wide measurement coverage, accurate fire detection position, high precision, etc., can effectively save manpower and material resources, and reduce line resource and property losses.

Description

technical field [0001] The invention relates to a mountain fire detection device and method, in particular to a wide-area real-time mountain fire monitoring device for a power grid based on a multi-spectral thermal energy monitoring radar. Background technique [0002] With the continuous improvement of my country's economic development and construction to the reliability of power supply, the impact caused by power interruption is becoming more and more intolerable. The transmission line is the main artery of the power grid, which affects the safe operation of the power grid. Especially in recent years, with the rapid construction of important transmission lines such as EHV / UHV lines, large-scale power transmission lines, and cross-regional networking lines, a number of transmission lines have gradually formed. The important power transmission channels with large capacity and dense arrangement will have a greater impact and impact on the power grid after the failure of these...

Problems solved by technology

[0004] Most of the commonly used fire detection methods currently rely on the reports of on-duty personnel and tourists, but this is neither automatic nor too dependent on personal judgment

In addition, some organizations use infrared artificial satellite imaging systems, but this method can only reflect the spread of power line forest fires, but it is difficult to detect small-scale wildfires

Moreover, it is not easy to analyze the infrared images. It takes at least one to two hours for the organization to detect the location of the fire.
