Problems solved by technology

[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. Shock data

Embodiment Construction

[0029] see Figure 1 to Figure 6 , a method for filtering steel-biting impact data triggered by a working condition signal, comprising the following steps:

[0030] Step 1, rationally select the real-time working condition data of the production line as the working condition judgment parameter of the real-time process state of the rolling mill;

[0031] Step 2, combining the actual operating conditions and working conditions of the production line, configure the process judgment threshold of the working condition judgment parameters;

[0032] Step 3, the edge computing control system reads the working condition judgment parameters in real time, and through logical judgment, it is determined that a steel biting event has occurred in the rolling mill at the current moment;

[0033] Step 4, when it is judged that a steel biting event occurs, the edge computing control system delays triggering the corresponding sensor channel of the vibration acquisition module to collect vibrati...

Abstract

A method for filtering steel-biting impact data triggered by a working condition signal, comprising the following steps: Step 1, selecting real-time working condition data of a production line; Step 2, configuring the judgment logic of working condition judgment parameters; Step 3, determining the current moment A steel bite event occurred in the rolling mill; step 4, collect vibration data and temperature data; step 5, display data and equipment status. The filtering method based on the working condition signal proposed by the present invention is more targeted to the actual operation of the equipment, and avoids the source of abnormal data from the source of collection, thus avoiding the impact data of steel bite impact in the production process from causing equipment early warning. interference, effectively reducing false alarms and making early warnings more accurate. At the same time, the filtering of abnormal data also screens effective data that can be used for diagnosis in the diagnosis process of equipment failure, and provides a data basis 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...
