AI Technical Summary
Existing light source driving circuits are limited in form and function, and cannot work continuously according to different light emission requirements at the same time, which limits the use of short-wave infrared icing sensors.
A driving circuit comprising four circuit unit modules was designed. By controlling the combination of optocouplers and single-pole single-throw analog switches, stable driving of the light source in four working states was achieved, namely normal operation, optical lower threshold emission, optical upper threshold emission, and constant current source driving.
It has enabled the shortwave infrared icing detector to operate normally, ensuring the safety of aircraft flight. By using different light intensities, it meets different working requirements and improves the detection accuracy and reliability of the detector.
