Abstract:To effectively make up for the inadequacy of traditional fire monitoring method, accurate analysis of fire development situation, will be a new generation of weather radar is applied in fire monitoring, opened up a new world in the field of fire monitoring, the weather radar to around 120 km within the scope of the terrain environment scanning, on the basis of the principle of doppler technology criterion of ignition, can quickly identify latitude and longitude coordinates after the fire ignition in six minutes, developed a mobile client apps at the same time, when the received radar system transmitted to the ignition of the latitude and longitude, The software searched and found that the line patrol personnel of the pole tower and the line guard within a certain range near the fire point could respond to the early warning information in a timely manner. At the same time, the radar to detect the smoldering fire monitoring effect is better than other methods, has good all-weather monitoring, monitoring of continuity, found early, early warning and more accurate positioning, more can detect other monitoring system can''t early warning of fire. The application case shows that in the Qingming festival, winter and other vulnerable mountain fires, the work of mountain fires prevention and control is greatly promoted, which is helpful to reduce the number of jumping accidents caused by mountain fires.
