Embodiment Construction
[0018] The infrared radiation temperature measuring instrument is composed of an optical system, a photoelectric detector, a signal amplifier, a signal processor, and a display output. The infrared radiation emitted by the radiation source enters the optical system of the infrared radiation temperature measuring instrument. The optical system collects the infrared radiation energy of the target in its field of view, modulates the infrared radiation into alternating radiation by the modulator, and converts it into a corresponding electrical signal by the detector. , the signal passes through the amplifier and signal processor, and is transformed into the temperature value of the measured target according to the built-in algorithm of the instrument.
[0019] The goal of redshift radiation dyeing temperature measurement is to eradicate the problem of radiation emissivity and fundamentally improve the accuracy of temperature detection by radiation thermometers. Among the component...

In the invention, based on a 'bathochromic shift-dyeing' principle, non-black-body radiation is converted into blackbody radiation, bathochromic shift radiation is solved from a three-dimensional higher-order overrunning function to a linear function of a first degree, solved data is compared with a real temperature of a measured radiation source, thus a so-called 'lifelike temperature' close to the real temperature is obtained. An experiment proves that: the lifelike temperature of 'bathochromic shift-dyeing' temperature measurement is quite close to the real temperature of the radiation source, fluctuation of a deviation of the 'bathochromic shift-dyeing' temperature measurement is far better than resolution of traditional radiation temperature measurement maximal precision (+ / - 1.0%), precision of the of the 'bathochromic shift-dyeing' temperature measurement is a level higher than precision of conventional radiation temperature measurement, and is very close to precision of a standard temperature when carrying out contact temperature measurement on the radiation source. A signal received by bathochromic shift radiation dyeing temperature measurement is an order of magnitude higher than a signal received by the traditional radiation temperature measurement, and a received signal is strong, which means that anti-interference is strong and reproduction is stable. A calibration operation of dyeing temperature measurement is carried out under a non-black-body radiation condition, thus a puzzle of setting radiation emissivity is eradicated.
Description
[0001] 1. Technical field: [0002] Redshift radiation dyeing temperature measurement belongs to non-contact infrared radiation temperature measurement technology. Because it eliminates the trouble of non-black body radiation emissivity ε, it can be directly applied to temperature measurement and temperature control of each smelting process such as sintering, ironmaking, steelmaking, steel rolling, etc. It is also applicable to energy, environmental protection, chemical industry, kiln, scientific research, aerospace, etc., covering every link that requires non-contact temperature measurement, temperature adjustment, and closed-loop control. [0003] 2. Background technology: [0004] Infrared radiation temperature measurement technology is an ancient and young subject. The basic law of black body radiation was fully established as early as a hundred years ago, but the application of infrared radiation temperature measurement technology has not stepped beyond the threshold of t...
