Title:
CONTROL METHOD AND APPARATUS FOR FOURIER TRANSFORM INFRARED SPECTRUM ANALYZER, AND STORAGE MEDIUM AND COMPUTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/080451
Kind Code:
A1
Abstract:
A control method and apparatus for a Fourier transform infrared spectrum analyzer, and a storage medium and a computer device. The method comprises: acquiring a peak value of an infrared signal starting parameter; when a moving mirror and a fixed mirror are perpendicular to each other and the peak value of the infrared signal starting parameter is a preset maximum peak value, obtaining a laser signal starting parameter at this time; acquiring a preset operating scanning frequency of a voice coil electrical motor; acquiring real-time values of temperature and humidity data, a laser signal operating parameter and an infrared signal operating parameter according to the preset operating scanning frequency; comparing the real-time values of temperature and humidity data with preset values thereof; comparing the difference between the laser signal operating parameter and the laser signal starting parameter with a preset difference value; and when the real-time values of temperature and humidity data are equal to the preset values thereof, and the difference between the laser signal operating parameter and the laser signal starting parameter is equal to the preset difference value, outputting the infrared signal operating parameter, such that it can be ensured that the moving mirror and the fixed mirror are perpendicular to each other during operating, and the resolution when the spectral analysis is performed for the output infrared signal operating parameter can be improved.
