摘　　要：颗粒传热实验测控系统是为颗粒换热平台设计的测控系统。该系统基于分布式系统EPICS架构设计,通过对NI硬件平台、红外热像仪设备以及Oracle数据库进行集成,实现了颗粒换热平台实验的在线采集、监测、控制与实时存储。由于红外热像仪具有灵敏度高、测温范围广、非接触测温等优点,因此在该测控系统中用于测量颗粒在换热器出口处的温度。本文使用SDK将其集成到EPICS系统中,利用红外图像更加直观地呈现出颗粒的实时温度分布,并提取红外图像中的数据,与热电偶的测量数据对比,进一步检测利用红外热像仪作为一种颗粒实时温度测量设备的可行性。实验结果表明,集成后的红外热像仪操作软件能够实时提取并存储红外图像中的温度数值,并且采用EPICS架构设计、开发的颗粒传热实验测控系统完全可以满足颗粒换热平台的数据采集与存储需求。The measurement and control system of particles heat transfer experiment was designed for the particles heat exchange platform.Based on the EPICS(Experimental Physics and Industrial Control System)architecture design,this system integrates NI hardware platform,infrared thermal imager equipment and Oracle database to realize the online collection,monitoring,control and real-time storage of particles heat exchange platform.The infrared thermal imager was applied to measure the temperature of particles at the outlet of heat exchanger in the measurement and control system for its advantages in high sensitivity,wide range of temperature measurement and non-contact measurement.In this paper,the SDK(Secondary Development Kit)was employed to integrate infrared thermal imager into the EPICS system.Infrared images and the data were obtained to present the real-time temperature distribution of the particles more intuitively.By comparing the data with the measured results of the thermocouple,the feasibility of using the infrared camera as a real-time temperature measuring device for particles was further tested.The experimental results show that the integrated infrared camera operating software can obtain and store the temperature values of the infrared image in real time.And the measurement and control system of particles heat transfer experiment designed and developed by EPICS architecture can fully meet the data acquisition and storage requirements of the particles heat exchange platform.
