Automatic Meter Reading System Of Rural Power Grids

In this paper, the countryside gird has introduced,based on the research of the formerly application, the remote aumotic measuring system for the countryside grid,which has three communications such as CAN bus, lower power line carrier communication and GPRS is prented. This paper emphasizes data collection module data convergence module and data communication module of system. The system can be divided into three layers, first layer is data collection module between Charging terminal and data collection organ based on CAN bus, second layer is date convergence module betweem data collection organ and data convergence organ based on lower power line carrier communication, third layer is data communication module between data convergence organ and date center based on GPRS.The Automatic Meter Reading System designed by this paper fully account the actual situation of the rural power grid, uses of various communication technologies, has preferable practical value.
