摘要: 变电站电气设备相对位置及金属特性影响变电站RFID(RadioFrequency Identification)监测系统通信性能.针对其类似隧道环境及多金属介质特点,提出了基于多天线技术的变电站设备状态传感标签监测系统,建立了监测系统信道模型,并分析了多天线RFID监测系统的性能影响因素.实验结果表明,阅读器天线与传感标签间距离小于80 m时,相比单天线及双收发天线监测系统,4收发天线系统通信误码率最大可降低1至3个数量级;通信距离在25~80 m时,垂直布置多天线方式较水平布置方式误码率可降低20%~40%.

Abstract: The relative positions of electrical equipment and metallic character affect the communication performance of radio frequency identification monitoring system for substation. Considering the tunnel-like environment and metallic media in substation, a RFID(Radio Frequency Identification) tag-sensor monitoring system for electrical equipment in substation based on multi-antennas is proposed. The channel model of monitoring system is built and the performance influence factors are analyzed. The results reveal that, when the distance from the reader antennas to the tag-sensor d is less than 80m, the bit error rate of four-antennas system can be reduced one to three orders of magnitude than that of two-antennas and single-antenna systems. When 25 m < d <80 m, the bit error rate of antennas vertically placed mode is reduced from 20% to 40% than that of horizontally placed mode.

Key words: electromagnetic propagation, multi-antenna RFID monitoring system, the channel model, performance analysis
