Concentrated Ammeter Reading System Based On GPRS And ARM

Concentrated Ammeter Reading System is a system which integrated modern management, computer applications, modern communication technology, automatic control, information and other multi-disciplinary technologies. This completed system realize the function of the power of the marketing control, power marketing management, sales Collecting, data collection and network connectivity etc.In this paper, the design of ARM based on the GPRS technology, make full use of the advantages GPRS real-time online communication, according to the flow of billing, and high-speed transmission. The system is based on Huawei's GTM900-B module that apply a small amount of data transmitted occasions, without achieving agreement PPP data transmission functions and users could also carry out data delivery function.GPRS and ARM-based centralized meter reading system has three main components: System Management Center (main station) based on NET platform, network based on the GPRS and the communication terminal, based on ARM platform system. System Management Center is responsible for data collection, storage and analysis; the terminal system carries out the information collection and control for the remote power system equipment; communications network set up a data transmission link between management center and terminals. GPRS and ARM-based system meter reading system has enriched the previous application of the original system, and enhanced overall performance of centralized meter reading system.After testing, this system can realize smoothly carry out a dial-up, sent and received data with the normal master , can realize normal collection of meter data management and achieve the desired results and design requirements. The system has been applied by a certain scale in Shishou in Hubei Province, Huanggang, Huangshi, Hunan Shiyan and some counties and cities. In the complex environment of the power supply such as Shishou region, all District 20 meter data can be correctly collected to the main stations on time, and the terminals can also master the normal response to an order to achieve the functions of the design. All this proved that the system is stable and reliable, and is advantaged to conducive the operation of distribution network security and economic management, It has also played a positive role to strengthen management and improve the power quality of grid electricity.
