The system captures hot spots (possibly fire events) from satellites, UAVs and ground cameras, and obtains fire event information from forest rangers. More than a dozen satellites scan the reserve at different frequencies every day. After intelligently analyzing the satellite scanning information, the system automatically selects the hot spots and sends out hot spot alarm; In case of bad weather and dense clouds in the protection area, the system can send UAV to fly at low altitude to scan the protection area, screen hot spots from the video images scanned by UAV, and send hot spot alarm; The network composed of thousands of ground cameras can monitor the situation of the protected area in real time, automatically analyze the images obtained by ground cameras, screen hot spots, and then send hot spot alarm; 140000 forest rangers were scattered to patrol every corner of the reserve. Once a fire  is found, they can immediately call the fire department through the system. Satellites, UAVs, ground cameras and forest rangers cooperate with each other, greatly reducing the time to find hot spots and fire events.
