Background
Currently, the current state of the art commonly used in the industry is such that:
a submarine mine is an underwater weapon used to attack submarines and surface vessels. Because the submarine mine sweeper is arranged on the seabed, the submarine mine sweeper is not easy to sweep, the attack time on a target is short, and an enemy cannot take countermeasures and implement an avoidance motivation, so that the submarine and various surface ships can be attacked effectively, but with the development of a mine sweeping technology, detection equipment and mine sweeping devices of the submarine and the surface ships are more and more advanced, and the detonator technology of the submarine mine is required to be improved and updated. At present, besides the old three field fuses of ship sound, magnetism, water pressure and the like which are commonly used, the research and the development of new physical field fuses are actively carried out at home and abroad. Such as electric field fuses, gravity field fuses, seismic wave fuses, cosmic ray field fuses, nuclear radiation field fuses, and laser fuses. The ship seabed seismic wave fuse is applied to the mine in America and Russia, and a series of products of the seismic wave fuse mine are developed. And the seismic wave fuze detects and identifies the target by using the seismic wave signal of the target. However, as with other detonators, the functional integrity of the mine detonator needs to be checked before the mine enters a armed state, a so-called mine detonator self-check operation.
The self-checking of the seismic wave fuze mainly comprises the steps of setting a working mode of the seismic wave fuze and detecting the functional integrity of the seismic wave fuze. The self-checking of the functional integrity is to detect whether the seismic wave fuze can accurately measure seismic wave signals, and the detection quality of the seismic wave fuze directly influences the working capacity of the seismic wave fuze. Therefore, in the self-checking work of the seismic wave fuze, the most critical step is to detect whether the seismic wave signal acquisition module in the fuze system can effectively and accurately acquire the seismic wave signal, however, since the module is integrated in the whole fuze system, the self-checking of the part is complex and tedious. At present, self-checking of a seismic wave acquisition module in a seismic wave fuze system is carried out by using special self-checking equipment through an external interface of the system according to certain self-checking steps, and large manpower and material resources are often needed.

(5) Self-checking results are difficult to distinguish, the existing self-checking equipment lacks self-checking result display capability, only each index outputs a result, the self-checking results need to be judged manually, and errors are easy to occur.
(6) And a self-checking system hardware system is complex and difficult to maintain.
The difficulty of solving the technical problems is as follows:
(1) how to design the self-checking system capable of being fused with the fuze system needs to solve the problem of compatibility of the fuze system and the self-checking system.
(2) How to realize the sharing of the self-checking system and the fuse system hardware and simplify the self-checking system.
(3) How to generate an effective, accurate and recognizable self-checking signal needs to solve the problem of electromagnetic interference between a fuze system and a self-checking system.
(4) How to realize a simple and efficient self-checking method and ensure the reliability and credibility of the self-checking result.
(5) How to simplify the self-checking step, reduce human input, design one-button self-checking mode.
(6) How to realize the intelligent self-checking result display capability and make the self-checking result easy to distinguish.
The significance of solving the technical problems is as follows:
(1) and special self-checking equipment is omitted, and the self-checking input cost is saved.
(2) A simple self-checking method is designed, the time cost of self-checking investment is saved, and quick self-checking is realized.
(3) The original self-checking mode is overturned in the plate type self-checking system, a feasible self-checking mode is provided for self-checking of other systems, and great theoretical guiding significance is achieved.
(4) The intelligent self-checking result display capability is achieved, and the self-checking result is more accurate and reliable.
