This method mainly relies on the acoustic response release device to write to the underwater integrated control system through the mother ship deck operation unit according to the task time and work requirements before launching into the water. Into the regular working time, the sound response release device starts timing after it enters the water and works. The acoustic response release device adopts a real-time clock chip, which has accurate running time and timing function. It can realize the timing release function according to the actual situation. The data storage module can realize the recording of attitude data and depth data.

The sound response release device drives the release mechanism to complete the release work process as follows: The sound response release device also has the function of timed release. Before launching, according to the task time and work requirements, it writes to the underwater integrated control system through the deck operation unit of the mother ship.
