Abstract: Aiming at the problems that multiple motors in the traditional pressure system cannot cooperate and the pressure room needs regular inspection, an intelligent pressure system is designed. By adding programmable control cabinet to the control side and introducing fuzzy control algorithm, the functions of press air supply, load balancing and automatic rotation of the air pressure system are realized. Through the fault diagnosis device and video analysis camera to realize the monitoring of equipment and personnel, to ensure the safety of people and things. The control platform of the intelligent compressed air system displays various data of the compressed air fan and displays the analysis results. The application of this system reduces the waste of electric energy, provides accurate diagnosis results, and improves the level of intelligent coal mine.
