Remote Data-Collection Technoligy Based On Three-Phase Energy Monitoring System

This paper presents abroad review of remote transformer monitoring system by analyzing the present conditions of its application and monitoring mode. We state the availability of the remote electric quantity monitoring pattern. The electric parameters of transformer can be transmitted by all kinds of network and carriers, such as GPRS,PSTN,CATV, GSM and optical fiber. Combined the current situation of our country, transmitting the data by the GPRS has much more advantage.The monitoring system of Remote electric quantity Based on GPRS obtains the electrical parameters of transformer by the data acquisition module, host Computer dials every monitored station by roll polling. Inferior processor transmits datas to the computer in superior monitoring center through GPRS for storage and processing, to provide the analysis and statistics for the supervisor section. The system is simple and cheap, and it will have a good prospect of application in electrical system.Remote data reading and transfer takes an important position in real-time Communication system. Remote data reading and transfer system can realize functions of remote command and supervision. The Remote Reading system is a neighborhoods intelligence management system based on the theory of remote data reading and transfer. In this article, how to realize the functions of the Remote Reading system through reading, storing and transfer of data is analyzed. As well, contents about theories and application of intelligence data bus, the terminal reading module and center module are also concerned.In hardware system design, we adopted the micro controller of lpc932 as the main controller of Inferior processor; it is used to choice three-phase enerny. C language is used to program the software of the device to realize the data transmission between cs5460 and Single–chip Microcomputer.If the Monitoring System is put to use, the old working mode has been changed, the management level and work efficiency has been improved, As a result, personnel and material resources are saved. it is extraordinarily fitted for monitoring load, maintenance and management of relatively scattered transformers, many economic and social benefits have been obtained apparently.
