Unmanned aerial vehicle spraying control method based on temperature and pressure monitoring

The invention provides an unmanned aerial vehicle spraying control method based on temperature and pressure monitoring. The method comprises the following steps that initialization is performed firstly after the electrification of an unmanned aerial vehicle spraying system is completed, and periodical starting is performed to collect a temperature value and a pressure value after the initialization is completed; when the detected temperature value is lower than a temperature lower limit value t1, a controller controls a temperature control switch to be switched on so as to start heating, and when the detected temperature value is higher than a temperature upper limit value t2, the controller switches off the temperature control switch so as to stop heating; when the detected pressure valueis lower than a pressure lower limit value p1, the controller starts a motor to work and controls a frequency converter to gradually increase the pressure through a first control value; when the detected pressure value is hi
