Xia Kun, Zhu Linling, Miao Sen, Xinyue Xu · 2014
The Air-Conditioner control system based on PROFIBUS uses bus topology which can communicate among a monitoring station, a class-one integrated master station and slave stations. It realizes real-time acquisition of air-conditioner equipment state through PLC, and then it can transmit the data information to the PC configuration software WINCC. In the PLC software design, system uses fuzzy control algorithm to realize the automatic control of valve actuators in air conditioning control system. The proposed system has been successfully applied to the control process of a commercial building to realize optimal control, operation and management.
