Considering the precision and cost of sea - route in our country , gps oem board was selected positioning for system in stand - alone model ( not dgps ) . there is abundant time to processing and optimizing data for gps receiver because the reactive speed of pharos is on hour level contrast to strict real time 根據航道定位精度要求與成本承受能力,系統選取低成本的gpsoem板接收機進行單機定位,由于航標燈監控有一定實時性但又非嚴格意義上的實時性,其反應速度可到小時級,這為gps接收機定位提供了寬裕的時間作為數據處理與優化。

At the same time , the parameter monitoring circuit is designed to check the operational parameters of pharos that include voltage of power supply , operational current , based on lm339 voltage comparer , optical sensor and logical circuit 以lm339電壓比較器為核心,結合光傳感器、邏輯電路等,設計出參數檢測電路,監測航標燈的電源電壓、工作電流等工作參數。

Model construction and realized method of pharos radio remote monitor terminal system are discussed in the thesis - , feasibility and rationality is analyzed for every module 探討了航標燈無線遠程監控終端系統組建模式與實現方法,逐個模塊分析其實現合理性與可行性。

This thesis analyzes the demand of pharos management and researches a radio remote terminal for monitoring the pharos on - line using new technology 本課題全面分析了航標燈管理維護的要求,結合快速發展的新興技術,研究了一種對航標燈在線監控的無線遠程監控終端系統。
