摘要
分析红外辐射光转换的原理及方法,研制红外辐射测温系统,用于高速运动物体的温度检测。从实际应用情况入手,对硬件电路设计、温度标定以及温度曲线拟合进行了详细论述。硬件电路设计主要包括光电转换、前置放大和恒温模块。设计温度标定实验获取数据。经多个模型比较,选用了指数模型,用来拟合电压温度曲线并进行了拟合误差分析。最后给出了整个系统的测试效果。
This paper analyzed the principle and method of infrared radiation conversion, developed an infrared radiation tem- perature measurement system for high-speed moving objeet temperature detection. Starting from the actual appheation,it discussed in detail about the hardware circuit design, the temperature calibration and temperature curve fitting. Hardware eireuit design in- eluded photoeleetrie conversion, pre-amplifieation and temperature modules. It designed the temperature calibration experiments to obtain data. It chose the exponential model to fit the temperature curve after eomparing several models,then presented the error a- nalysis. Finally, it showed the testing results of the whole system.
