Abstract: Taking coal handling system of a thermal power plant as the research target, an intrinsic safety intelligent control system for coal handling is designed according to the intrinsic safety management requirements of coal handling system. The system is based on intelligent sensor technology, Internet of Things technology and modern digital information technology in its architecture design, and the advanced algorithms such as image recognition, big data analysis and artificial intelligence are applied in its functional module design. The intelligent control system finally forms seven functional modules, including violation and abnormality identification, personnel positioning, real-time monitoring of equipment status, belt inspection robot, intelligent access control, intelligent water flushing and occupational health, etc., which comprehensively improves safety in personnel, equipment, operation and the environment, and finally realizes the intrinsic safety of coal handling system.
