摘要
为了能实时测量高温场的温度分布及图像,提出了基于红外探测技术、光电转换技术的高温测试系统的总体设计方法,完成了硬件的选型与设计及系统处理与控制软件的开发。系统采集到的高温温度场的图像数据经过串行网络信号转换器、光端机的转换,实现了温度场数据的远程传输及处理;图像数据处理计算机控制指令通过光端机对图像采集单元的参数及运行进行控制。本测试系统最后被成功应用于某型试验,远程取得了温度场的瞬时温度分布。实验结果验证了红外高温测试系统的有效性与实用性。
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.
