摘　　要：当节点的规模较大以及外界干扰较强时,会导致物联网节点安全控制域监测精度较低等问题。针对上述问题,设计并提出基于光纤复用的物联网节点安全控制域监测方法。组建物联节点之间的通信传输信道模型,通过光纤复用技术进行物联网信道特征参量估计;利用自适应信息融合跟踪检测方法进行物联网节点定位。针对监测任务量大的特点,选用多路复用和定位扫描方式实现安全控制域监测。仿真实验结果表明,控制域监测时间较短,监测误差最低,监测精度最高可达到80%,较好地实现了同一域内部距离较小、不同域间的距离较大的安全域划分结果,具有较好的准确性以及实用性。When the nodes scale is large and the external interference is strong,it will lead to the problems such as low monitoring accuracy of the security control domain of the IoT node.Aiming at the problems above,this paper designs and proposes a method for monitoring the security control domain of IoT nodes based on optical fiber multiplexing.The communication transmission channel model between IoT nodes is established,and the characteristic parameters of IoT channels are estimated by fiber multiplexing technology.The adaptive information fusion tracking detection method is used to locate IoT nodes.In view of the large amount of monitoring tasks,the multiplexing and positioning scanning methods are used to realize security control domain monitoring.The simulation results show that the monitoring time of the control domain is short,the monitoring error is the lowest,and the monitoring accuracy is up to 80%.The security domain partition results of the same domain with small internal distance and large distance between different domains are realized,which has better accuracy and practicability.
