Research on Intelligent Infrared Detector for Carbon Monoxide Used in Mine

Using infrared technology to detect the concentration of carbon monoxide. The system was controlled and processed by single-chip microcomputer intelligently. Double lamp-houses and double detectors was adopted to compensate the influence of impure gases and dusts. Temperature and pressure of surroundings were compensated by algorithm, and kinds of interface to fulfill keyboard, display, alarm and up-down functions were designed.
