Introduced self-developed power line carrier automatic meter reading system. The system uses power line to transmit data. The system microcomputer and SCM cooperate to complete the automatic transmission and system maintenance of meter data. It can form a huge and reliable communication network through telephone network, twisted pair and power grid. The system of the host computer to VisualFoxPro as the development platform, the standard interface and interface design, the system is easy to maintain; 89C2 0 51 using the next crew to complete the development of the underlying communication protocol. The entire system networking convenient and convenient construction.
