[0028] The present invention will be further described in detail below with reference to the drawings and embodiments.
[0029] See figure 1 , Example 1 A gas emission monitoring instrument in a tunnel, including a data processing module 1, containing MSP430 series single-chip microcomputer, memory and peripheral circuits, used to store and analyze and process data, according to the formula Q=GVS and numeric keyboard 6 input Calculate the gas emission from the tunnel section information, and output the gas emission together with the gas concentration and wind speed at the same time, where Q is the gas emission, G is the gas concentration, V is the wind speed, and S is the tunnel cross-sectional area. Gas concentration sensor 2, used to detect gas concentration information. The signal conditioning circuit 3 composed of an amplifier circuit and a filter circuit is used to amplify and filter the gas concentration signal and the wind speed signal detected by the gas concentration sen...
