摘要
针对高校实验室供电系统缺少有效监测设备的实际情况,设计了一种基于嵌入式平台的数据监测系统;系统由采集节点、无线网络和上位机组成,利用IEEE 802.15.4的ZigBee进行数据传输,通过STC90C516RD+和ADE7758的有效结合,实现了数据采集、计算分析和诊断报警功能;测试结果表明,该系统平均故障率低于0.77‰,控制响应时间低于40ms,具有实时性好、稳定及可靠性高等特点。
According to the real situation of lack of monitoring device for laboratory power supply system in colleges and universities, this paper designed a data monitoring system based on embedded platform. This system is composed of collection node, wireless network and PC. The data is transmitted by ZigBee based on the IEEE802.15.4 . With the combination between STCg0CS16RD-＋- and ADE7758, the system can realize functions of data collection , analysis , diagnosing and alarming. The testing results show that the system failure rate is lower than 0. 77 %, the control response time is less than 40ms, and performance of which is real--time, stable and reliable.
