This new system is based on micro control unit ( mcu ) , gps , gis and gsm technologies and has incorporated advanced features such as real - time monitoring of buoy position , battery voltage , and status of lighting system 有针对性地提出了基于单片机（微控制器） 、 gps技术、 gis技术及gsm通信技术的航标灯（浮标）远程实时监控系统方案。
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电压比较器为核心，结合光传感器、逻辑电路等，设计出参数检测电路，监测航标灯的电源电压、工作电流等工作参数。
Only regeneration energy can be selected for system power supply for complex and across distribution of rivers , which brings to the system power consumption an outstanding problem , optimization for power consumption was full considering in this thesis 由于航标灯工作于野外，分布错综复杂，因此只能选择可再生电源作系统电源。相对有限的电池供给使得系统功耗成为一个突出问题，系统从元件选择到软硬件设计对功率进行了优化。
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 根据航道定位精度要求与成本承受能力，系统选取低成本的gpsoem板接收机进行单机定位，由于航标灯监控有一定实时性但又非严格意义上的实时性，其反应速度可到小时级，这为gps接收机定位提供了宽裕的时间作为数据处理与优化。
