Remote Meter Reading System Based On GPRS Network Software

Energy management has become more and more important for enterprise management. It’s absolutely essential for energy management to acquire comprehensive real-time energy consumption data before enterprise can take further steps. Remote Meter Reading System which is consisted of local data-acquisiting uints and remote ternminal units (RTUs) can transfer energy data through GPRS network. The system reliability is a very import factor because the system needs uninterrupted running.In the thesis, system requirements are analyzed firstly and the system artchitecture and core modules are introduced in very detail. Some GPRS network features like connection-less, channel instability etc, which may cause data-lost during transmission are also discussed. Based on the analyzation of GPRS network, the application-layer protocol and extra conventions to make communication stably and accident recovery rapidly is designed and implemented for both of the data server and RTUs.The implementation of core modules of system is introdueced according to system functional and non-functional requirements.The software testing is an important way to meet the functionality and reliability of the system. Unit testing for core modules and blackbox testing for the protocol are introduced in the thesis.
