一种海洋潜标适用的新型GPS信标机

摘要

A new GPS beacon is designed for the ocean subsurface mooring to improve the positioning efficiency and accuracy during the recovering process.The beacon is mainly integrated by a GPS module,a data transmitter,an internal microprocessor module and a pressure switch.When the subsurface moorings are deployed,the beacon is fixed on the subsurface floats and its power is controlled by the pressure switch.While the floats reach the surface of the ocean,the power switches on and the transmitter on the beacon can send out the GPS information processed by the internal microprocessor module.This GPS data is received by the client server in some distance and can be displayed on the personal computer（PC）.With the aid of this GPS beacon,users can efficiently get the location of the recovered mooring,which can greatly facilitate its recovery.%本研究设计了一种潜标适用的新型信标机,它集成了GPS模块、数传模块、微处理器和压力开关等部件,可有效提高潜标回收过程中的目标定位能力。该信标机安装于潜标主浮体,通过压力开关控制电源。当主浮体位于海面时,信标机处于工作状态,它可以不断地将GPS位置数据通过无线传输方式向外发送,配套的接收端可以将接收的位置信息直观地显示在PC机上。作业人员据此可以迅速准确地确定主浮体的位置,提高潜标回收作业的效率和成功率。
