摘要
GPS授时以其高精度、实时、抗干扰、技术成熟等优点被诸多领域所应用.研究设计了基于GPS高精度水电站授时系统,该系统可以通过RS232C和RS485输出接收处理后的本地时间,以及由GM-82 OEM板直接发送的1PPS和NMEA-0183 ASCII码定位导航时间信息.
GPS timing is widely used in various fields with the merits of high precision, real time;anti-disturbance, mature technology and so on. Precision timing system, based on GPS in hydropower stations, is studied and designed. It transmits local time through RS232C and RS485 to other devices. In addition, IPPS and NMEA-0183 ASCII information about timing, navigation and position are directly transmitted by GM-82 OEM circuit.
