| 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. |
