[0002] During tunnel construction, the air quality at the face is a key factor affecting construction safety and the health of construction workers. During tunnel excavation and construction, the ventilation requirements in the tunnel change according to different face areas, tunnel depths, wet spraying and other working conditions. Traditional tunnel ventilation systems mainly rely on external fans, and specialized personnel manually adjust the operating frequency of the fan motor. This method is not only inefficient, but also unable to respond to changes in the air quality inside the tunnel in real time. With the development of tunnel construction technology, the demand for real-time monitoring and automatic adjustment of the air quality inside the tunnel is increasing. Therefore, it is particularly important to develop an intelligent control system that can automatically monitor and adjust the air quality inside the tunnel. Summary of the invention
