Abstract: In order to overcome the problems of low efficiency and poor accuracy of traditional abnormal data capture, this paper proposes an industrial IoT communication abnormal data capture method based on node clustering. First, analyse the structure of Industrial Internet of Things (IIoT), collect communication data and extract the characteristics of industrial communication data; then, the node subordination function is constructed, and the abnormal data types are divided by common neighbour node analysis. Finally, the matching degree between features is extracted through node clustering calculation, and the matching degree is input into the classifier function and the communication exception data capture result is output. The results show that the malicious node capture rate of this method is always higher than 92%, the capture time is always less than 3.6 seconds and the effect of abnormal data capture of IoT communication is improved.
