Abstract: |
A kind of multi-channel parallel power-frequency communication system is developed,which contains mainly the substation system and the user terminal equipment. Key hardware circuits and their connections are given. The key technologies of downlink signal transmission/detection,uplink signal transmission/detection are researched. Three-phase signal parallel transmission,single-phase six-channel signal transmission and multi-feeder signal parallel transmission are applied to enhance the transmission rate of system data. The terminal address code and communication protocol compatible with DL/T698-41 standards are designed. The multi-channel parallel communication system transmits data much faster than the single-channel communication system does,which satisfies the demands of electric energy data acquisition system. |
