Therefore, it is necessary to monitor and warn the visibility (VI) and harmful gas (CO) concentration in tunnels in real time to avoid accidents.

[0003] At present, tunnel COVI detectors on the market mainly adopt two structures: one is a single-body type, in which the transmitting lens and the receiving lens of this structure are integrated, the distance is relatively close, the detection space is small, the air circulation in the tunnel is not smooth, harmful gases will accumulate and the suspended distribution of particulate matter will be uneven, and the monitoring data in the small detection space is not representative; the other is a split type, in which the transmitting lens and the receiving lens are set at the transmitting end, and a reflector is set at the reflecting end. The detection light emitted by the transmitting end is shot to the reflector after a certain distance, and the light is reflected back to the receiving lens of the transmitting end. This structure has high requirements for the alignment of the light path during installation. At present, the split COVI detector is aligned by adjusting the angle between the base and the connecting plate of the transmitting and receiving end and the reflecting end.
