摘　　要：温度和流量测量是热力试验中的重要环节,设计了一种基于虚拟仪器的温度流量测试系统。运用美国国家仪器公司的Lab-VIEW工具软件和研华公司的ADAM4000模块,实现了系统控制参数设置、温度流量数据采集与处理、数据及曲线显示、数据保存等多种功能。系统成本低廉、设备简单、可靠性高。试验结果表明系统运行稳定,实现了预期功能。Measurement of temperature and flow rate is an important part in thermodynamic tests. A temperature and flow rate measuring system based on virtual instrument has been developed. The system is composed of LabVIEW tools software from NI USA and ADAM4000 module from Advantech. The functions of the system include setting control parameters ; data acquisition and processing for temperature and flow rate ; displays of data and curves; and data storage, etc. The system features low cost, simple equipment and high reliablity. The results of experiments prove that the system operates stably and realizes expected functions.
