摘要
针对现有接地线缺乏自动化管理的现状,设计了一种基于RFID和ZigBee技术的临时接地线在线监测系统。系统中采用基于ISO14443A标准的RC522读卡芯片实现接地线状态信息的可靠采集,通过基于IEEE802.15.4标准的CC2530芯片实现信息的准确传输。文章实现了系统硬件电路和软件架构设计,并进行了全面测试,针对变电站环境中的电磁干扰、障碍遮挡和网络拥塞等问题,提出了增加路由节点、调整发信间隔等通信可靠性改进方案。该系统可以实现对变电站作业现场临时接地线挂接状态的在线实时监测,可靠性高,效果良好,有较高的推广价值。
In view of the current situation that grounding wire is lack of automatic management,a grounding wire online monitoring system based on RFID and ZigBee technology is designed in this paper. In this system,RC522 reader chip based on ISO 14443 A standard is used to achieve reliable information collection in the state of grounding wire,and the CC2530 based on IEEE 802. 15. 4 standard is used to achieve accurate information transmission. This paper completes the design of hardware circuit and the software architecture,and conducts a comprehensive test. Considering the electromagnetic interference,obstacles blocking and network congestion issues in a substation,it proposes improved communication reliability programs,such as to increase routing nodes,adjust letter spacing,etc. The system can achieve real-time monitoring of the status of temporary grounding wire in a substation job site,with high reliability and good effect,and it is worth being extended.
