The Design Of Building Automation System Based On LonWorks Technology

With the development of information tecthnology,building automation system is accepted universally.LonWorks technology became the instructive technological document GB/Z 20177 of Chinese national standard.Due to its strong openness,flexibility,reliability and interoperability,it is now one of the most popular Field Bus,and is wildly applied in the field of building,transportation,environmental monitoring and so on.According to the development and reality of building automation system,combining the main characteristics of LanWorks bus,and based on LonWorks technology,this paper provides a design plan of intelligent building automation system.Furthermore,this paper completes the hardware and software design of the control system of air-conditioning.On this Project,the BAS is the backbone,and air-conditioning control system is three nodes.Major research achievement:(1)Research on hardware and software of Lon Works technology.(2)According to the customer need,analyze the principle and control requirement.(3)Design the detection nodes and intellective valve foe temperature and humidity to control the air-conditioning intellectuality,and also consider the comfort and energy conseration.(4)Use the Nodebuilder platform to debug,and make the nodes dynamic link to network.Then realize the network manage and integrated network.
