Research on Multiple Drive Coordinated Electrical Braking Technology for Long-Distance Belt Conveyors
In response to the problems of unreliable electrical braking,difficult monitoring of braking performance,and easy misjudgment in long-distance belt conveyors with multiple drive modes,this paper explores the coordinated control braking technology of long-distance belt conveyors with multiple drives.A variable frequency speed regulation device is adopted and a harmonic electrical braking unit module is proposed.Wavelet packet analysis is used to decompose harmonic signals and accurately obtain speed regulation and braking parameters.By establishing relevant algorithm control models and using support vector machines to achieve health diagnosis and fault warning during the braking process,it was finally found through on-site experiments that the coordinated electrical braking of long-distance belt conveyors with multiple drives can directly reflect the operating status of the equipment by utilizing changes in equipment operating parameters,effectively ensuring the reliability of electrical braking and reducing the misjudgment rate of fault monitoring.Effectively reducing the accident rate and ensuring the stable operation of long-distance belt conveyors have important reference value and significance for improving the braking detection and ensuring the braking performance of long-distance belt conveyors.
