Abstract: Due to factors such as the long-term operation of industrial conveyor belts, accidents of belt breakage in bulk material upward conveyor belts often occur. The belt breakage monitoring and protection system is mainly suitable for monitoring the catching of sliding broken belts when a broken belt accident occurs to prevent it from causing significant economic losses and personal injury accidents. This article analyzes the advantages and disadvantages of existing representative broken belt monitoring and protection technologies, analyzes the key requirements and pain points that need to be focused on in broken belt monitoring and protection technology, and has designed a new solution. The application of the new belt breakage protection system can improve the safety factor, operational stability and efficiency of the belt conveyor area. After the application of the new protection system and digital transformation, the belt conveyor system can easily connect with the production management system in the factory to provide data support. The belt conveyor system can be upgraded and transformed according to the intelligent integration platform of the belt conveyor to improve overall production efficiency.
