Intelligent detection method of sensing data exception under physical attacks of large-scale industrial sensor network information

Abstract

The invention discloses an intelligent detection method of sensing data exception under physical attacks of large-scale industrial sensing network information, and belongs to the field of sensor dataexception detection. The method comprises the the steps of standardizing sensor data; introducing an imaginary sensor, and carrying out data expansion on the standardized data; converting the one-dimensional sensor data into a two-dimensional data format; directly generating a grey-scale map from the two-dimensional data; classifying the converted pictures by using a convolutional neural network (CNN) classification algorithm; and expanding the number of sensors to the thousand-level or ten-thousand-level, and checking the expandability of an exception detection model and the application of the exception detection model in a large-scale industrial sensor network. Multiple simulation tests are carried out, and multiple evaluation indexes are adopted to compare the exception detection modelsbased on different algorithms. The method provided by the invention can solve the problem that the sensing data of the industrial sensor network has a complex relationship, meets the requirements ofreal-time performance and accuracy of the industrial network, and has good expansibility.
