[0052] This embodiment provides a method for monitoring performance parameters of an AGC cylinder that introduces an adaptive optimization algorithm, such as figure 1 As shown, the AGC cylinder performance parameter monitoring method that introduces an adaptive optimization algorithm includes:

[0053] S1, obtaining the characteristic parameters affecting the performance of the AGC cylinder;

[0054] It should be noted that the failure of the AGC cylinder in the project is mainly caused by problems such as internal leakage, jamming and servo valve, and the main reason reflected in the performance parameters is the change of the response speed of the piston or cylinder.

[0055] Specifically, in this example, the input parameters are: operating side AGC cylinder position setting value, operating side AGC cylinder position actual value, driving side AGC cylinder position setting value, driving side AGC cylinder position actual value, operating side inlet magnetic ruler position...

Abstract

The invention discloses an AGC cylinder performance parameter monitoring method introducing an adaptive optimization algorithm. The method comprises: acquiring characteristic parameters influencing the performance of an AGC cylinder; calculating a rolling mill roll gap and an AGC cylinder response speed; calculating the deviation between the operation side roll gap and the transmission side roll gap, evaluating the rolling mill roll gap and the deviation between the operation side roll gap and the transmission side roll gap, and outputting alarming in a graded mode; and calculating the deviation between the response speed of the AGC cylinder on the operation side of the rolling mill and the response speed of the AGC cylinder on the transmission side, evaluating the response speed of the AGC cylinder and the deviation between the response speed of the AGC cylinder on the operation side of the rolling mill and the response speed of the AGC cylinder on the transmission side, and outputting alarms in a grading manner. According to the invention, through online acquisition of the AGC cylinder parameters, real-time analysis of the working state of the AGC cylinder and evaluation of the current performance of the AGC cylinder, historical performance state and development trend analysis, fault hidden danger early warning and timely reminding of maintenance personnel for inspection are realized, and the AGC cylinder fault early warning method has a significant effect in reducing and even eliminating AGC cylinder faults.

Description

technical field [0001] The invention relates to the technical field of mechanical automation, in particular to an AGC cylinder performance parameter monitoring method which introduces an adaptive optimization algorithm. Background technique [0002] The development of metal pressure processing technology requires higher and higher quality standards for strip products, and the development of technology depends on the development of rolling equipment. The working status and parameters of steel rolling equipment will directly affect the quality and production efficiency of steel strip products. Therefore, the research on online monitoring and fault diagnosis technology of steel rolling equipment plays a vital role in improving the core competitiveness of steel enterprises. [0003] In the traditional AGC cylinder performance test, the performance test of the AGC cylinder can only be carried out in the off-line state, usually periodically or after an accident, in the state of ov...
