AI Technical Summary

Technical Problem

Traditional pressure monitoring methods are unable to fully reflect pressure distribution and dynamic changes. In particular, under complex working conditions and equipment vibration, it is difficult to distinguish between real pressure signals and noise interference, and cannot provide reliable equipment control basis. They lack comprehensive analysis of pressure distribution and material motion state, and cannot meet the high-precision and intelligent control requirements of modern industrial production.

Method used

A pressure sensor array-based method is adopted to generate a direction-sensitive pressure feature matrix by matching gradient direction analysis with material motion direction, track the spatial displacement of pressure center to generate kinematic feature vector sequence, use pre-trained model to output evolution state information, generate risk heat map to identify abnormal areas, and convert it into equivalent tension physical model.

Benefits of technology

It enables comprehensive and accurate monitoring and dynamic analysis of pressure distribution, eliminates measurement deviations, provides reliable equipment control basis, and can provide early warning of abnormal movement trends, thereby improving production efficiency and product quality.

Abstract

The invention discloses a pressure mapping method based on a pressure sensor array, and the method comprises the steps: carrying out the gradient direction analysis of an original pressure matrix outputted by the pressure sensor array in real time, carrying out the matching with the motion direction of a material, and generating a direction sensitive pressure feature matrix; direction sensitive pressure feature matrixes generated at different collection time points are obtained in a preset time window, a track sequence is obtained, a pressure distribution kinematics feature vector sequence is generated and input into a pressure evolution state prediction model, and evolution state information is output; generating a single-point-global pressure evolution feature vector of each sensor unit, inputting the single-point-global pressure evolution feature vector into a sensing unit pressure mapping anomaly recognition and evaluation model, and outputting a local risk value of the sensor unit; and generating a risk thermodynamic diagram according to the local risk value of each sensor unit in the pressure sensor array, and identifying a pressure mapping abnormal region. Therefore, accurate monitoring, analysis and abnormal mapping of pressure distribution in the material movement process are realized.
