    Automatic Matching System of Mine Standard Gas

    • This paper describes a set of automatic matching system about mine standard gas. The system, based on PC and C8051F020 microcontroller, uses automatic control gas-matching technology and mass flow controller to control gas-flow rate, and adopts infrared gas detection module to detect gas concentration and prepare standard gas of required concentration.
