The invention, which relates to recorder recovery in the aerospace field, specifically to an underwater positioning searching method which is used for recorder recovery and capable of underwater long-range positioning searching, solves the problem that the recorders are difficult to find and recover once the recorders fall into the sea. A protection crust of a recorder is provided with a plurality of auxiliary positioning devices. A hit-split crust is arranged outside the protection crust of the recorder. Stuffing and a dye pack filled with coloring agents are disposed between the protection crust and the hit-split crust. The hit-split crust is provided with a plurality of buoys that can break away from the hit-split crust. The method comprises the steps of (1) automatically starting of apiece of sonar equipment; and (2) searching and positioning including direct underwater searching and positioning and indirect overwater searching and positioning. The recorder in the invention has asimple peripheral structure, and the searching and positioning method is reasonable. Therefore, the underwater recovery of the recorder can be realized effectively and accordingly important data in the recorder can be obtained, thereby facilitating the development of aerospace industry.
Description
technical field [0001] The invention relates to the recovery of recorders in the aerospace field, in particular to an underwater positioning and searching method for recovering recorders capable of remote positioning and searching underwater. Background technique [0002] At present, the aerospace field often needs to recover some recorders that store important data. Once the recorder falls into the water, it is often difficult to find and recover, making the data unobtainable, which has caused great constraints to the development of the aerospace industry. . Contents of the invention [0003] In order to solve the problems in the current aerospace field that the recorder is difficult to search and retrieve once it falls into water, the present invention provides an underwater positioning and searching method for recovering the recorder. [0004] The present invention is realized by adopting the following technical scheme: a method for underwater positioning and searchin...
