| Abstract: | Realize the remote and automatic meter reading course based on reliable low voltage power line power frequency communication(PLPFC) . The system based on two parts:one is PC, the other is MCU. We could realize the communication between PC and MCU by such networks as GSM,etc. PC is the data administrative center, MCU is used to gathering the data and to transmit PC's instruction.Concentrator is the kernel of MCU, the communication in MCU is realized through low voltage PLPFC,that is, concentrator gathering the meter's reading from meter reading unit(MRU) or transmitting the PC's instruction to MRU through low voltage power line. The principle and course of realizing the communication between concentrator and MRU through low voltage PLPFC has been described in detail in the article, and the corresponding topology of hardware circuit and flow chart of procedure has been provided too. We analysed the system's characteristic in the end of the article. |
