The invention provides an avionics system of an oil-driven direct-driven multi-rotor unmanned aerial vehicle, which comprises a power supply management unit used for converting battery voltage into voltage required by a flight control unit and an engine control unit and correspondingly distributing the voltage; the engine control unit is used for controlling normal work of the two-stroke engine and sending the engine rotating speed numerical value, the engine temperature numerical value and the self-state data which are read in real time to the flight control unit. The ground control unit is used for transmitting the differential positioning information to the flight control unit in real time; the flight control unit is used for sending instructions to the engine control unit and the power management unit according to the engine rotating speed value, the engine temperature value, the self-state data and the differential positioning information which are acquired in real time to control the unmanned aerial vehicle to work. By means of the method, the problems that when multiple engines of an avionics system of an existing oil-driven multi-rotor unmanned aerial vehicle work cooperatively, the engine performance consistency is poor, and compared with a motor, the engine is long in response time, high in non-linear degree and the like can be solved.
