Research on High Precision Time Information Transmission Method

Time synchronization system has been widely used in power system. According to the needs of different system, it provides different signals. Usually you can use a GPS clock pulse, serial message, IRIG-B yards and so on. B code contains both plus and serial time message .And the traditional equipment is often used pulse and serial message at the same time. We put forward a method to transmit pulse information and serial message information on a transmission line .And at receiving place, it can restore the signals. It can reduce line costs and outside interferences, is beneficial to the optimization of system.
