Abstract The Profibus based centralized air conditioning control system is really capable to implement the target of real time“decentralized control，centralized management”，and overcome the vital disadvantages of conventional centralized air conditioning control system，e. g. ，vaste energy，poor regulating capability on comfortable，low reliability，and hard to meet the requirement of real time communication control. Thus，the Profibus based system will be applied more and more extensively in the area of building automation. The system is introduced in this paper，mainly the hardware and software
design of the system are analyzed.
