Research and application of running status online monitoring system for large-scale vibrating screen
The operation status monitoring of vibrating screen is mainly based on manual experience currently,and the traditional online monitoring methods are difficult to meet the intelligent needs of large-scale vibrating screen due to the poor accuracy.On the basis,an running status online monitoring system for vibrating screen was developed,and the its composition and main functions were outlined.To overcome the technical problems of poor accuracy of traditional single-axis or three-axis single-direction vibration sensors,a virtual space three-dimensional coordinate system was established for the vibrating screen.The motion vector synthesis algorithm was used to reconstruct the actual vibration direction angle and vibration intensity of the monitoring sites of the screen,overcoming the influence of the sensor installation accuracy and on-site working conditions on the monitoring results,and achieving accurate measurement of screen machine vibration data.By using the temperature sensors,the temperature curve of the bearing was obtained,which realized the accurate perception of temperature data.Based on real-time data from temperature sensors,the bearing temperature rise curve was obtained,achieving precise perception of temperature data.By analyzing abnormal data,a vibration screen operation anomaly and early warning model was established based on support vector machine.The on-site application showed that the online monitoring system has achieved digital recognition and early fault warning of the running status of the vibrating screen,significantly reducing the failure rate of screening equipment and ensuring efficient and stable operation of the equipment.
