[0022] Such as figure 1 As shown, a method for real-time measurement of the absolute gas emission in a tunnel, the method includes the following steps: S1: Install a linear laser sensor on one side of the tunnel section, and arrange three groups from top to bottom, of which the first group is installed 30cm below the tunnel vault, the other two groups are installed evenly according to the height of the tunnel, and the linear laser sensor is irradiated to the other side of the tunnel section, and the average concentration of gas on the beams of the three groups is measured; S2: Install the wind speed sensor in step S1 The laser sensor measured the wind speed of the tunnel section at 50cm below the vault of the same tunnel section; the wind speed sensor detection data was compared with the manual detection data, and the correction between the measured value of the wind speed sensor at this point and the average wind speed value of the tunnel was obtained under different wind spee...
