摘要
设计了基于GPRS和AT89C52的远程电力监测系统,采用单片机来实现电力参数的交流采样,用LCD显示所采集的电力参数。通过GPRS网络将采集到的数据发送给后台机管理系统来完成数据的保存、统计查询、分析和打印等。实验结果表明,采用交流采样方法提高了系统的精度和稳定性,简化了硬件电路。
The remote electric power monitoring system based on GPRS and AT89C52 has been designed. The electric parameters that are collected by AC sampling method and single chip computer can be shown on LCD display. Through GPRS, the data collected are transmitted to background computerized administration system for data storage, statistical enquiry, analysis and print-out, etc. The result of experiments indicates that by adopting AC sampling method, the accuracy and stability of the system have been enhanced, and the hardware circuits are simplified.
