Method for filtering out occluding steel impact data based on working condition signal triggering

Abstract

A method for filtering out occluding steel impact data based on working condition signal triggering includes the following steps of firstly, selecting real-time working condition data of a productionline; secondly, configuring a judgment logic of working condition judgment parameters; thirdly, determining an occluding steel event of a rolling mill at the current moment; fourthly, collecting vibration data and temperature data; and fifthly, displaying date and a device state. The filtering-out method based on a working condition signal is better targeted at the actual operating conditions of adevice, the source of abnormal data is avoided from the root of collecting, and therefore the interference caused by the occluding steel impact data in the production process to early warning of thedevice is eliminated, misinformation is effectively reduced, and early warning is more precise. Meanwhile, by filtering out the abnormal data, the effective data capable of being used for diagnosis isscreened out in the diagnosis process of device failures, and a data basis is provided for subsequent diagnosis.

Description

technical field [0001] The invention belongs to the field of predictive maintenance of mechanical equipment, in particular to a method for filtering steel-biting impact data triggered based on working condition signals. Background technique [0002] In the field of predictive maintenance of mechanical equipment, the vibration and temperature data of mechanical equipment under operating conditions are the basis for predictive maintenance of equipment. Therefore, it is very important for the predictive maintenance of equipment to ensure the validity and reliability of the collected data by preprocessing the collected data. In the hot rolling process of the metallurgical industry, the rolling mill is the key equipment for hot rolling production. During the biting process of the rolling mill, due to the speed difference between the hot-rolled billet and the rolling mill roll, rigidity will be generated when the billet and the roll are in contact. shock. [0003] Because the vi...

[0004] However, the vibration data of the impact of the steel bite has the characteristics of uncertain frequency components, fast impact attenuation speed, and large differences in the shock vibration data collected by sensors at different positions, so that it is difficult to screen out the steel bite from all the collected vibration data through data analysis.
