Abstract

The invention relates to a method for visualizing fault state monitoring. The method comprises the following steps of: 1) setting fault characteristic parameters and vector directions; 2) determining the position of a composite vector CF; 3) visualizing a plurality of characteristic parameters on a two-dimensional plane; varying the position of the determined composite vector CF with the values of the fault characteristic parameters F={f1, f2,..., fn} to realize the visualization of the plurality of characteristic parameters on the two-dimensional plane. The method is used for an operator of a digit control machine to monitor the abnormal working state of the machine and brings about solution that correctly discriminates the working state of the digit control machine in the absence of monitoring samples of the abnormal working state; furthermore the problem of the visualization of the characteristic parameters is solved, and a new method is provided for monitoring the state of the digit control machine. The method is also suitable for monitoring the state of other devices.

Description

technical field

[0001] The invention relates to a fault state monitoring method, in particular to a monitoring visualization method. Background technique

[0002] The good flexibility and high machining accuracy of CNC machine tools make them the main equipment in modern production systems. And with the improvement of the automation degree of the production system, the role played by the CNC machine tool is also increasing. Once a failure occurs, the loss caused to the production system is also increasing. Therefore, it is becoming more and more important to carry out condition monitoring and fault diagnosis on processing equipment. The main purpose of condition monitoring of equipment is to ensure the safe operation of the processing system, avoid equipment failure, ensure processing quality, and improve production efficiency and equipment utilization. In order to effectively monitor the state of the CNC machine tool, it is often necessary to judge the working state of th...
