摘　　要：为了避免因为变电站机房内的交换机众多而造成故障难以排查的情况,本文基于物联网实现多功能水晶头与交换机端口自动匹配。选取RJ45水晶头调节电路模块,通过射频识别技术实现多功能水晶头和交换机端口的识别和定位,基于设备标识匹配、信号强度匹配以及网络拓扑结构匹配三种算法完成功能水晶头与交换机端口的自动匹配。实验发现,本文自动匹配算法下延长系数在1.0左右,设备识别准确率为94.37%,设备识别用时为37ms,且网络开销维持在4bit左右。本文算法下多功能水晶头与交换机端口自动匹配度程度最为理想,且设备识别率最高,网络开销小。In order to avoid the situation where faults are difficult to troubleshoot due to the large number of switches in the substation room,this article implements automatic matching between multifunctional crystal heads and switch ports based on the Internet of Things.Select the RJ45 crystal head adjustment circuit module and use radio frequency identification technology to identify and locate multifunctional crystal heads and switch ports.Based on three algorithms:device identification matching,signal strength matching,and network topology matching,automatic matching of functional crystal heads and switch ports is achieved.The experiment found that under the automatic matching algorithm in this article,the extension coefficient is around 1.0,the device recognition accuracy is 94.37%,the device recognition time is 37ms,and the network overhead is maintained at around 4 bits.The automatic matching degree between the multifunctional crystal head and the switch port under the algorithm in this article is the most ideal,and the device recognition rate is the highest,with low network overhead.
