Abstract: The remote power meter reading system consists of the data center,remote data transmission gateway,and web page data display system.Gateway data acquisition is an important part of system design,which includes bus communication,protocol analysis, data encapsulation,and network transmission.Remote power meter reading system uses RAM926EJ microprocessor as the core of the embedded system gateway;the gateway uses Modbus RTU communication protocol;the network communication uses TCP/IP protocol; C++ is used to develop the gateway program and data reception. Through the experimental tests,data acquisition for real-time power and total power consumption from multiple electric meters was achieved,and the data was sent to the server through the Internet. |
