摘要
基于国际航海标准NMEA-0183为数据协议,以保证电力系统精准授时为目的,通过ARM微控制器STM32f103rbt6和高精度GPS接收模块NEO-5Q为核心控制数据采集和传输,实现了GPS同步授时的设计方案。系统采用GPS接收模块接收卫星发送的标准数据串,通过微控制器对GPRMC最小定位信息中的时间数据进行筛选和处理,最后经上位机授时软件对本地计算机进行成功校时,保证了系统的可行性。
Based on the international maritime standard NMEA-0183 data protocol,with the purpose to ensure accurate calibrating time for power system,by using ARM microprocessor STM32f103rbt6 and high precision GPS receiving module NEO-5Q as the control core to realize the data collection and transmission,this paper achieved the design of GPS synchronous calibration time system.It utilized GPS receiving module to receive the standard data string which was transmitted by satellite,after selected and processed the time data of the GPRMC minimum positioning information by microprocessor,finally, if succeeded to correct the local computer's time through the computer software,and ensured the feasibility of the system.
