Design of Centralized Remote-reading Meter System and Intelligent Network Water Meter

This paper describes a design to develop a centralized remote-reading meter system which used to overcome shortcomings of the traditional manpower-based reading meter. The system is designed from the host computer, network meter and concentrator three parts. Concentrator is connected to the host computer, so remote meter could be read, monitored and managed by the host computer. The host computer consists of client, server, data service and database, developed by C# language and SQL Server. The network water meter is based on STC89C52RC microcontroller sending data to the concentrator through 485 bus. The concentrator taking ARM9 and Linux as the core, read meter data by 485 bus, and send data to server through Ethernet. The test results show that the remote- reading meter system is accurate, simple, real-time, secure, reliable, and easy to application.
