Abstract: A proactive deviation correction scheme that integrates deviation detection, automatic deviation correction, and protection is proposed to address the current problems in the practical application of deviation detection and correction methods. A deviation correction vertical roller with a two-stage rotating mechanism is used as the core mechanism for deviation detection and correction, and the corresponding monitoring system is designed. The system uses sensing devices such as inclination and displacement to accurately sense the deviation distance of the belt, and establishes a high-speed communication network centered on CAN bus. The deviation angle is accurately and automatically controlled through remote upper computer analysis and calculation. The effectiveness of the design is verified through experimental applications, and the active deviation correction of the belt under unmanned intervention is realized. It has certain practical reference significance for effectively improving and ensuring the safe and stable operation of the belt conveyor.
