Abstract: To address the challenges of low accuracy and insufficient reliability in real-time monitoring of lateral and longitudinal vibration displacement in multi-rope hoisting systems of mines, a non-contact vibration displacement monitoring system based on 3D camera was developed.This system utilizes 3D camera to synchronously monitor the vibration displacement of multiple wire ropes, and leveraging a B/S architecture-based vibration displacement monitoring software platform, enables efficient data acquisition, stable transmission, reliable storage, and visual analysis of wire rope vibration displacement.By processing point cloud data and calculating the deviation of the dynamic centroid position relative to the static position, precise measurement of wire rope vibration displacement is achieved.Static and dynamic tests were conducted in an actual mine hoisting system, and the experimental results indicate that the measurement error is approximately ±2 mm.The system demonstrates excellent real-time performance and stability, meeting the requirements for vibration displacement monitoring of wire ropes under complex working conditions and providing technical support for the safe operation of mine hoisting system.
