Ground unmanned aerial vehicle power supply network testing device

The utility model relates to a ground unmanned aerial vehicle power supply network testing device. A measurement and control channel of an engine is connected with an upper computer to transmit measurement and control data to the upper computer; the output end of the generator is connected in parallel with a plurality of equipment power supply input ends and a plurality of electronic load simulator power supply input ends; and the fan rotating speed sensor, the temperature acquisition module and the current and voltage acquisition module are connected with the upper computer to transmit sensing signals to the upper computer. And when the power supply network starts the high-power load, the rotation speed drop parameter of the engine is tested 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 t
