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.
