基于GPRS的电力线路监控系统

Design of power line monitoring system based on GPRS technology

简述了GPRS无线业务特点及其工作原理,重点讲述了基于GPRS的电力线路监控系统的组成、原理以及软硬件设计。该系统通过数据测量单元在线实时监测输电线路上振动信号、温度、湿度、风速、风向等数据,并将其传到监控中心,通过中心管理系统对电力线路振动情况进行统计、分析,做出正确的预测和评估,实现故障预警。实践证明,GPRS技术非常适用于要求实时性的、大数据量传送的应用场合。

The principles and characteristics of GPRS wireless service were described, and its makeup, its basic theory, and the design of the hardware and software of power line monitoring system were emphasized. The vibration of each power lines and their environment parameters such as temperature, humidity, wind speed, position and measuring time were all measured and sent to the monitoring center by GPRS, concerned with weather forecast and the historic data, and the vibration level of the power line was analyzed by the expert system, so whether an power line was working normally or not and where the faulted insulator could be known. It is proved that GPRS technology is applied for the field of real-time and large data transfer in practice.
