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。
In this paper, the field-bus technology Lonworks technology to establish variable air volume air conditioning decoupling control system, and the variable air volume air conditioning decoupling control system made a more detailed description of the proposed LonManagerDDEServer and VisualBasic established VAV air conditioning decoupling control system The LONWORKS network monitoring system approach. It is appropriate to consider the use of network variables in Lonworks technology to handle decoupling compensation coefficients between control loops. The system has the advantages of fieldbus technology, including the complete decentralization of the system control to improve the reliability of the system. Using Lonworks technology to control VAV air conditioning system can greatly improve the quality of VAV air conditioning system and improve the control system.
