【Abstract】 A remote centralized control system for fan filter unit(FFU)is developed to meet the market needs for a large number of air purification equipments. The system has the functions of patrol,alarm,communication,wind speed setting,current detection,group management,liquid crystal display,FFU drive,etc. For a large number of FFU devices,a low-power design is adopted for the FFU drive,which has the advantages of wide speed range,high stability,high reliability,and energysaving. The distributed star-type and bus hybrid structure is adopted in communication network structure. The control system is easy to operate and install,and has high expansibility. It is mainly used in large-scale sites such as factory workshop and subway ventilation and so on.更多还原
