摘　　要：本文在凝结换热试验台的基础上,开发了以组态软件为监控层,虚拟仪器Lab VIEW为控制层的监控和数据采集系统。Lab VIEW通过串口通讯完成对温度、压力、流量信号的采集以及对控制量的输出,采集到的数据通过动态数据交换传送到组态软件实时数据库,实现在监测界面下的动态显示、曲线分析和数据存储。试验表明,开发的控制器对试验台热水温度在设定值扰动下有较快的响应速度,且超调幅度小,稳定后控制精度为±0.1℃。A SCADA system based on configuration software as supervisory layer and LabVIEW as control layer was developed for the experimental plant of condensation heat transfer. Signals like temperature, pressure and flow are gathered and control output by LabVIEW through serial ports. Data collected is transferred to the database in SCADA system and will be displayed, analyzed and stored in the monitoring interface. The experimental results show that the PID controller can make the hot water temperature a faster response with a small overshoot and an accuracy of 0.1 ~C under set point disturbance.
