摘要
该文采用现场总线技术中的Lonworks技术建立变风量空调解耦控制系统,并对该变风量空调解耦控制系统作了较为细致的描述,提出了用LonManagerDDEServer和VisualBasic建立变风量空调解耦控制系统的LONWORKS网络监控系统的方法。认为用Lonworks技术中的网络变量来处理各个控制回路之间的解耦补偿系数是很合适的。该系统具有现场总线技术的优点,包括实现了系统控制的彻底分散化,提高了系统的可靠性。用Lonworks技术对变风量空调系统进行控制,可以极大地改善变风量空调控制系统的品质并提高控制系统的先进性。
Lonworks technology is adopted to set up VAV air-conditioning decoupling control system,this system is de-scribed in detail.LonManager DDE Server and Visual Basic are adopted to set up Lonworks network monitor system of VAV.It is suitable that decoupling compensation coefficient between four loops are handled as network variables of Lon-works technology.This system has the merit of fieldbus technology,which includes realizing the decentralization of system control and improving the stability of control system.Application of Lonworks technology in VAV air-conditioning decou-pling control system could improve the quality of VAV control system,and this system is advanced.
