Fault injection test system and method based on time synchronization flight simulation

The invention relates to the technical field of electronic system tests, in particular to a fault injection test system and method based on time synchronization flight simulation. Comprising a main control system, a flight simulation system, a satellite signal simulation/forwarding system, a bus fault injection system, a non-bus fault injection system, an environment control system, an environment control room and a cabin display system. The satellite signal simulation/forwarding system is connected with test equipment in the main control system, the flight simulation system, the bus fault injection system, the non-bus fault injection system, the environment control system and the environment control room. Whole-process simulation of flight is realized by editing scripts/scripts, consequences caused by injection of faults in all links of flight are researched on the basis, and meanwhile, time synchronization between a test system and airborne equipment is combined, so that the test environment is consistent w
