Design and Implementation of Metering Automation Terminal Based on EPON Communication Technology
Abstract:Based on EPON communication technology,the design of a metering automation terminal is realized based on EPON communication technology. The measuring terminal design with double light communication interface module design,to support the EPON network forms of communication and using single chip microcomputer and special-purpose metering chip hardware design,in order to improve the use of measuring terminal reliability and low power consumption performance. With the real-time operating system,the software system of the metering terminal is optimized and designed,so that it can realize automatic measurement,data upload,terminal status monitoring,human-computer interaction and other functions. Finally,the performance test proves that the measuring terminal has good data communication efficiency and reliability and can meet the design requirements.
