Background In the ground test or launching stage, if a major fault or abnormal situation occurs, the carrier must be able to quickly and reliably perform power-off control to cut off the power supply, preventing further damage to the product or causing a safety accident. The reliability of the power-off control is directly related to success and failure of tasks and equipment safety. However, different application scenes have different demands on the execution logic of the power-off control, namely, part of the vehicles have extremely high requirements on power supply safety in the flight process and need to prevent error power-off caused by electromagnetic interference or flight control software defects, so that the power-off instruction is required to be executed when a bus message and a switching value control signal sent by a ground test and control system are simultaneously valid, and the other part of the vehicles further emphasize the response flexibility in the ground test and require quick response in the case of abnormality, so that any one of the bus message and the switching value control signal is allowed to be effectively executed to perform power-off.
