Design of a Grounding Wire Online Monitoring System based on RFID and ZigBee
Considering the current situation that grounding wire is short of automated management, a grounding wire online monitoring system based on RFID and ZigBee technology is designed in this paper. In this system RC 522 reader chip based on ISO 14443A standard is used to achieve reliable information collection of the state of grounding wire, CC2530 based on IEEE 802.15.4 standard is used to achieve accurate information transmission. In this paper completes the design of hardware circuit and the software architecture, and conducts a comprehensive test, against the electromagnetic interference, obstacles blocking and network congestion issues in a substation, proposes to increase routing nodes, adjust letter spacing, etc. programs to improve communication reliability. 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,it is worth being extended.
