A communication method of auv module

Abstract

A communication method for an AUV module belongs to the field of underwater vehicles, and the invention solves the problem of poor stability of the AUV system caused by the lack of a watchdog in the communication module. The method of the present invention includes the following steps: step 1, power on the main control module and the communication module; perform steps 2, 3 and 4 simultaneously, step 2, use the communication module to send a heartbeat packet to the main control module and receive the return information from the main control module to Judging the working status of the communication module and the main control module; step 3, the duty module obtains the working status of the communication module and the main control module by querying the communication module; step 4, the duty module obtains the work of the main control module and the communication module by querying the main control module If the working state of the main control module is abnormal, restart the main control module; if the working state of the communication module is abnormal, restart the communication module. If the restart is still abnormal, the AUV will be controlled to float up urgently.

Description

technical field [0001] The invention belongs to the field of underwater vehicles, and relates to the system stability of the underwater vehicle. Background technique [0002] AUV (Autonomous Underwater Vehicle) is a submersible that can autonomously complete set tasks underwater with the assistance of support platforms such as land base stations and surface ships. AUVs initially completed work related to the civilian field, such as accident ship salvage, underwater environmental terrain exploration, underwater cable construction, underwater equipment deployment, maintenance and recovery, etc. But because it can carry a variety of sensors, special equipment, underwater countermeasure weapons, etc., it can complete many difficult military missions. Its military value has been paid attention to by more and more countries, and it has also been regarded as a "power multiplier" in naval equipment by the navies of various countries. At present, the design of AUV mostly adopts mod...
