Abstract

The invention discloses a spray control method for an unmanned aerial vehicle. The spray control method includes the steps that (1) a lower area is detected by using a flame detector, an altitude sensor and a temperature sensor; (2) it is detected by the flame detector that an infrared light radiation value of the lower area is higher than a set value; (3) the altitude sensor and the temperature sensor output current ambient altitude and temperature data and record the current ambient altitude and a current temperature; (4) after the unmanned aerial vehicle moves vertically downward once, a temperature of the current ambient altitude is detected and output by the temperature sensor, then the unmanned aerial vehicle moves vertically downward once again, the temperature of the current ambient altitude continues to be detected and output by the temperature sensor, and the temperature at the current ambient altitude is recorded; and (5) the infrared light radiation value of the lower areais detected again by the flame detector. The detection reliability of the spray control method for the unmanned aerial vehicle is high.

Description

technical field [0001] The invention relates to a spraying control method of an unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. There is no cockpit on board, but equipment such as autopilot and program control device are installed. The personnel on the ground, on the ship, or at the remote control station of the parent aircraft track, locate, remotely control, telemeter and digitally transmit it through radar and other equipment. Under the radio control, it can take off like an ordinary aircraft or be launched into the air with a booster rocket, and it can also be taken into the air by the parent aircraft for flight. When recovering, it can automatically land in the same way as the common aircraft landing process, and can also be recovered by remote control with a parachute or a block. Can be used repeatedly. Widely used...
