| 在辐射温度计检定中，根据规程要求，需要将辐射温度计的发射率设置为1，而在实际校准辐射温度计的过程中发现大量发射率固定且不为1的情况，同样有用户要求校准后给出不同发射率下的辐射温度计修正值，为实现宽波段任意固定发射率辐射温度计在校准过程中的修正值计算，文章使用LabVIEW的两分法迭代实现Plank公式的积分算法，有效提高校准过程的自动化程度，文章用实例说明了两分法与普通步进算法的效率区别，从而高效的实现了任意波段、任意发射率、任意温度点的温度修正值计算。 |
| 英文摘要: |
| In the process of radiation thermometer calibration, according to the verification regulation, the emissivity of radiation thermometers should be set to 1.00, while during the actual calibration process, the correction value of radiation thermometers with different emissivity values is required to give out by customers after the calibration and the emissivity is fixed and not equal to 1.00. In order to realize correction value calculation for wide-range radiation thermometers with arbitrary fixed emissivity in the calibration process, the article uses LabVIEW dichotomy iterative to achieve the integral algorithm of the plank formula and improves the degree of automation in the process of calibration effectively. The article verifies the difference of efficiency between dichotomy and common stepping algorithm, so that the correction value calculation could be efficiently implemented in any band, any emissivity, and any temperature point. |
