Background of using high-speed tunnel dust monitoring station
As a key node in the transportation network, high-speed tunnels have high traffic volume, enclosed space, and relatively limited ventilation conditions. During vehicle travel, friction between tires and road surfaces, exhaust emissions, and material scattering during cargo transportation can easily generate a large amount of dust. These dust particles not only reduce visibility inside the tunnel, interfere with the driver?s line of sight, increase the risk of traffic accidents, but also cause damage to the respiratory systems of passing drivers and passengers. At the same time, they accelerate the aging and corrosion of equipment inside the tunnel, affecting its service life and operational safety.
Traditional dust monitoring relies heavily on manual inspections or regular sampling at designated locations, which not only has low efficiency and lagging data, but also makes it difficult to grasp the dynamic changes in dust concentration inside tunnels in real time, and cannot take effective dust reduction measures in a timely manner for sudden high concentration dust situations. With the continuous growth of traffic flow and the increasing requirements for tunnel operation safety and environmental protection, high-speed tunnel dust monitoring stations have emerged to achieve real-time monitoring and accurate warning of dust concentration in high-speed tunnels, ensuring traffic safety and environmental quality.
