摘　　要：传统电源负载热失控监测系统监测准确性偏低。为此,设计基于物联网架构的远程直流电源负载热失控在线监测系统。网络层以TCP/IP协议为依据,完成跨地域的多个直流电源的运行状态的并行传输;采用核主成分分析提取状态信息特征,通过隐半马尔可夫模型完成多特征融合,实现在线监测。实验结果验证了该系统可完成数据的实时通信,传输延时短,并且可准确完成远程直流电源负载热失控以及引起的故障监测。The monitoring accuracy of traditional power load thermal runaway monitoring system is low. Therefore,a remote DC power load thermal runaway online monitoring system based on the internet of things architecture is designed. On the basis of TCP/IP protocol,the network layer completes the parallel transmission of the running state of multiple DC power sources across the region. Kernel principal component analysis(KPCA) was used to extract state information features,and hidden semi-Markov model(HMM) was used to achieve multi-feature fusion and online monitoring. The experimental results show that the system can complete the real-time data communication,short transmission delay,and can accurately complete the remote DC power load thermal runaway and caused fault monitoring.
