GROUND UNMANNED AERIAL VEHICLE POWER SUPPLY NETWORK TESTING SYSTEM AND TESTING METHOD

The present invention relates to a ground unmanned aerial vehicle power supply network testing system and a testing method. A measurement and control channel of an engine is connected to an upper computer to transmit measurement and control data to the upper computer; an output end of the engine is connected in parallel to power supply input ends of a plurality of devices and power supply input ends of a plurality of electronic load simulators; and a fan speed sensor, a temperature acquisition module, and a current and voltage acquisition module are connected to the upper computer to transmit sensing signals to the upper computer. Engine speed drop parameters of a power supply network are tested when a high-power load is started, so as to evaluate the safety of the flight process and provide a reference for the optimization of a subsequent flight strategy. A heat source is effectively evaluated, and cable routing and heat dissipation design are guided and optimized. Whether each device works in the input volt
