Design Of Trawl Sonar System Underwater Working Environment And Moving Posture Monitoring System

China is a big ocean country with rich fishing prospects, but the developmentequipment for fishing always gets behind. Ever since a long time ago, China is blind indeveloping ocean fishing prospects. Therefore, with the rapid development of our countryeconomy, intelligent development equipment for fishing is needed urgently to satisfy peoplethe need of developing rich fishing prospects. Trawl Sonar System is very advanced fishingaid equipment; it can provide scientific directions for fishing.This paper introduces the trawl sonar system of the development at home and abroad.This paper is set in the development of new trawl sonar system, a underwater workingenvironment and moving posture monitoring system is designed with MSP430F169single-chip microcomputer，temperature sensor, pressure sensor, posture sensor and othercore components. The system is not only used for monitoring oening trawl in ocean, but alsomonitoring temperature and pressure underwater. For the convenience of system debug,LCD is used for observing real time acquisition data and SD card is used for storing realtime acquisition information, for the convenience of doing futhter analyse and research later.Demonstration program, hardware platform design and software design of trawl sonarsystem underwater working environment and moving posture monitoring system are madein this paper and system software associate with hadware debugging is completed. Thesystem design achieves the expectant function requirements through laboratory test, butneeds further outfield experimental test.
