| 摘 要： | 针对温度控制中常用的基于铂电阻的温度采集电路设计复杂,抗干扰能力弱,铂电阻线性拟合繁琐,难以实现对温度的高精度测量等不足,本文介绍一个在VC++6.0平台上设计的基于机器视觉,自动读取水银温度计示数的温度测量系统。通过有效的图像处理算法,温度测量系统分辨率达到0.01℃,读数准确,工作可靠。该温度测量系统在研究大滞后大惯性温度控制实验中得到了成功的应用。

| Abstract: | Temperature data acquisition circuit based on platinum resistance,which is constantly used in temperature control system,is complex,weak on anti-jamming capability and low measuring accuracy,and its linear fitting of platinum resistance is very troublesome.This article describes a temperature measurement system to read the mercury thermometer automatically based on machine vision,designed on VC+ +6.0 platform.By applying some effective image processing algorithms,the temperature measurement system has resolution of 0.01℃,measures accurately and workes reliably.The temperature measurement system has been successfully applied in the temperature control experiment of large time-delay and large inertia. |
