Design of Remote Infrared High-temperature Measurement System

To measure the temperature distribution and image of a high-temperature field, a general design method of a high-temperature measurement system based on infrared detection and photoelectric conversion techniques is proposed. The selection and design of hardware and the development of processing and control software for the system are completed. The image data of a high-temperature field collected by the system are converted by both a serial Ethernet converter and optical terminals. Then, they are transferred remotely for processing. Finally, a computer for image data processing sends control commands for controlling the parameters and operation of the image collection unit through optical terminals. This measurement system is used in a particular test successfully and the instantaneous temperature distribution of a temperature field is obtained remotely. The validity and practicability of this infrared high-temperature measurement system are verified by the experimental result.
