Abstract:
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.
