Abstract

This invention discloses an automatic dust suppression system for belt conveyors under multiple operating conditions, belonging to the field of centralized control technology for industrial automation. It addresses the problem of poor dust suppression scheduling under various operating conditions. The invention rapidly identifies dust anomalies, sudden belt speed changes, and fluctuations in wind speed and humidity by constructing a closed-loop control system based on a global state map and disturbance segment identification. Based on propagation verification, it determines the set of dust suppression units affected by disturbances. Through constraint modeling and feasible solution screening, a programmed scheduling scheme is generated, taking into account safety interlocks, resource boundaries, and start / stop intervals. It uses minimal-range linkage for spraying, suction, and sealing, combined with local degradation control and centralized rolling rescheduling, to achieve unified on-site handling and global optimization. This further improves the system's adaptability and dust suppression effect, avoids ineffective full-line startup, reduces fault risk, and maintains stable operation.
