基于低压电力线载波通信的仪器动态监控系统设计与实现

Design and implementation of instrument dynamic monitoring system based on low-voltage power line carrier communication

为了能够实现在不采用无线发射的方式下对位置分散、随机搬动的贵重仪器进行精准定位和使用状态采集,本文基于低压电力线载波通信技术设计了一套仪器动态监控系统,通过采集终端对仪器开关机电流数据进行采集,上报集中器并进行房间定位。系统进行了小规模部署试验,结果表明该系统能够对仪器开关机使用状态的判别并对位置信息进行管理,特别适用于按照保密要求不允许无线发射的使用场所,可以实现对随机分散仪器的动态监控和统计分析。

In order to be able to accurately locate and collect the use status of precious instruments that are scattered and moved randomly without using wireless transmission,this paper designs a set of instrument dynamic monitoring system based on low-voltage power line carrier communication technology,and uses the acquisition terminal to monitor the instrument.The current data of the switch is collected,reported to the concentrator,and the room is located.The system has carried out a small-scale deployment test,and the results show that the system can distinguish the use status of the instrument on and off and manage the position information.It is especially suitable for use places where wireless transmission is not allowed in accordance with the confidentiality requirements.It can realize the dynamics of random scattered instruments,Monitoring and statistical analysis.
