Research on Conveyor Belt Slip Detection Using Optical Flow Technique and Encoder

This paper proposes a slip detection method for belt conveyors based on an optical flow technique and encoder. The researchers utilized optical flow techniques to measure the speed of the belt surface in real time. This data was then integrated with an encoder to determine the actual speed of the shafts. Based on the numerical relationship between the two, the occurrence of belt slippage is determined. The experimental results demonstrate that the method can effectively detect belt slippage with high accuracy and stability. Therefore, it is a reliable method to monitor the safe operation of belt conveyors.
