The method for detecting skin inlet and outlet valve faults according to claim 6, characterized in that: The skin inlet and outlet valve to be tested includes a first side plate and a second side plate, the first side plate is rotatably connected to the second side plate, the execution action data includes an actual opening angle, and determining whether the skin inlet and outlet valve to be tested fails based on the execution action data includes: Obtaining the actual opening angle between the first side panel and the second side panel of the inlet and outlet valves of the skin to be tested when performing the corresponding action; Based on the actual opening angle, determine whether the inlet and outlet valves of the skin to be tested are faulty.
10. The skin inlet and outlet valve fault detection method according to claim 9, characterized in that: The step of determining whether the inlet and outlet valves of the skin to be tested are faulty based on the actual opening angle includes: If the actual opening angle is consistent with the preset angle, it is determined that the inlet and outlet valves of the skin to be tested are faulty; Otherwise, it is determined that the inlet and outlet valves of the skin to be tested are not faulty.
