Design of Mine Carbon Monoxide Concentration Sensor Based on Quantum Cascade Laser
This article explores a method for detecting carbon monoxide concentration using mid-infrared quantum cas-cade laser technology.This method is based on the absorption characteristics of carbon monoxide molecules at specif-ic infrared wavelengths.By measuring the change in light intensity after the laser passes through the gas to be mea-sured,precise measurement of carbon monoxide concentration can be achieved.Due to the intrinsic safety and explo-sion-proof requirements of coal mine equipment,there are certain limitations on sensor energy consumption.In this ar-ticle,the laser adopts pulse current driving and dynamic adjustment of temperature control,which reduces the power consumption of the whole machine.At the same time,the sensor continuously monitors gas temperature and pressure,and combines with the random forest regression algorithm to correct and compensate the measurement results of the laser spectrum,thereby significantly improving the accuracy and stability of carbon monoxide concentration measurement.
