Fieldbus Lonworks Applied Research, The Temperature And Humidity Control System

The rapid progress of the information technology lead the marvelous change in the automatizaion domain.lt also forms the distributed network integration automation system and the interlinkage communicate network of opening system gradually.The former center air-condition control system often adopt the system based on RS485 BUS.But as the progress of the technology and the ceaseless requirement,it behind the times. Based on the analyse of the neuron network,lonworks and fuzzy control system,we establish a center air-condition control system to settle the problem of overmany tache, discommodious debug and auto bidirectional control.lt used lonworks BUS instead of RS485 BUS so as to integerate the computer and the local control system.Aim at the problem of easiness surge in the system adjust,wo set up a control arithmetic dopt the mode of fuzzy control integated PID control.In this way,the system possess not only nicer robust but also exact control.In the end,wo write the gate arithmetic from network to lonworks,entire flow chart and some procedure.By the emulate of the computer and actual fix,wo prove the efficiency of our method.Due to the mixture use of many methods,we advance the integrate function of the system notably. The actual result prove our system goes well and take on some theory meaning and biggish-extended value.
