Abstract

The invention discloses a monitoring and testing method, including acquisition of satellite monitoring sensitivity, for an electric-transmission-line mountain fire satellite monitoring system. The monitoring and testing method includes selecting a testing satellite, an open site, a season, weather, time and orbit azimuth angle conditions, preparing a ground monitoring and measuring device, taking firewood as a flaming material, laying a fire ground at the center of the site, recording coordinates of the fire ground, setting fire to the fire ground before satellite transition, observing a quick satellite view in real time and recording time spent by system preprocessing during satellite transition, repeating fire-point judgment after pre-processing, observing whether the satellite can find the test fire ground or not until finding the critical length of the testing satellite finding the fire ground, and squaring the critical length to acquire the sensitivity of the testing satellite. The monitoring and testing method can be used for acquiring sensitivity, distortionless reception range and fire-point judgment threshold of the monitoring system under the conditions such as different weather and territories, thereby having great guiding significance for operation and accuracy improvement of the electric-transmission-line mountain fire monitoring system.

Description

technical field [0001] The invention relates to a test method for mountain fire monitoring, in particular to a monitoring test method for a transmission line mountain fire satellite monitoring system. Background technique [0002] Mountain fire disasters occur frequently on transmission lines, and the tripping of transmission lines caused by mountain fires has become one of the main factors that endanger the safe and stable operation of the power grid. Mountain fires near transmission lines have the characteristics of small fire area and rapid fire. Therefore, once a mountain fire occurs, prevention and control measures should be taken as quickly as possible. The use of satellites to monitor the occurrence of wildfires on transmission lines can detect wildfires in sparsely populated places in time, and provide valuable guidance information for emergency response to wildfires. [0003] There are still many problems in the existing satellite mountain fire monitoring system, s...
