Car body electric control system testing platform based on hardware-in-the-loop

The invention discloses a car body electric control system testing platform based on hardware-in-the-loop. The car body electric control system testing platform comprises an upper computer (1), a testing equipment cabinet (2), a mobile terminal bench (3) and a laboratory car bench (4). The testing equipment cabinet is composed of a plurality of modules. The terminal bench is used for connection among the testing equipment cabinet, a controller to be tested and the laboratory car bench. The laboratory car bench is used for constructing switches of the whole car body and real loads. The upper computer is connected with a PXI real-time controller in the testing equipment cabinet through a network cable and monitors the operation of the testing platform in real time. An equipment cabinet power supply input module of the testing equipment cabinet is externally connected with a power supply and realizes power distribution and system protection of the equipment cabinet power supply. The mobile terminal bench is conn
