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.
