description The invention belongs to the test technology of aviation lifesaving instruments, and relates to a device for detecting the action time of an automatic unlocking device and a detection method. In a negative pressure state corresponding to a simulated height, a soft lock needle is used for replacing a height diaphragm capsule to accurately lock a lever position when the automatic unlocking device reaches a preset unlocking height, and after an environment where the automatic unlocking device is located recovers to a local air pressure, the action time of the automatic unlocking device from starting work to unlocking release is accurately captured through a photoelectric induction mode. Compared with an original sound control testing method, the device and detection method can complete locking and unlocking functions in the negative pressure environment of the simulated high and can accurately measure the action time. According to the prior art, the gear starting sound of an automatic unlocking device is monitor
