基于LABVIEW的变风量空调数据采集和控制系统的构建

变风量系统中建立一套对房间的温度、湿度、CO2浓度等各种信号的采集以及对各种水阀、风阀、变风量箱、电加热器、加湿器等其它控制元件的精确测量与控制的数据采集控制系统。使用NI公司的Lbview软件以及控制工具包,把变风量系统中各种不同设备统一起来,进行集中采集与控制,建立起一个大系统对后续的系统辨识、仿真、控制以及优化提供一个平台。

Builds a suit of VAV DAQ and control system which could take precise data acquisition of temperature,humidity,CO2 concentration of room and control water valve,air valve,VAV box,electrical heater,humidifier and other control element s.Using National Instrument＇s product LabVIEW,unites all different devices in VAV system to take central control. Builds a large-scale systems of VAV which supply a plan of Identification,Simulation,Control and Optimization.
