Use of wind speed and direction detectors in tunnels

Tunnel wind speed and direction detector is a special device for measuring wind speed and direction in underground tunnels. The detection probe is installed on the tunnel wall to supply tunnel wind speed and wind direction detection value to the tunnel general control room as the fundamental basis for ventilation and operation. The detector can observe the operating status and detection data of the instrument in real time in the field, and the analog and switching signals sent by the data output interface can be connected with the PLC in the adjacent sub-control room, and then connected with the general control room by optical fiber through the data optical terminal.

In the construction, operation and maintenance of underground tunnels, tunnel wind speed and direction detector plays a very important role. Here is a detailed introduction to its use:

1. Ensure tunnel safety: During the operation of underground tunnels, the wind speed and direction in the tunnels will have an impact on vehicle driving, personnel safety and smoke emission. Tunnel wind speed and direction detector can measure wind speed and direction in real time, and output relevant data. Operators can formulate corresponding measures according to this data to ensure the safety of tunnel operation.

2. Optimize tunnel ventilation: In order to ensure the safety of tunnel operation and reduce the content of pollutants such as tail gas concentration and carbon monoxide, the tunnel needs to be ventilated. Through the data obtained by the tunnel wind speed and direction detector, the ventilation condition in the tunnel can be understood, so as to adjust the ventilation volume and direction to achieve the optimal ventilation effect.

3. Optimize tunnel design: In the process of underground tunnel construction, different tunnel structures and materials have different effects on air flow. Wind speed and wind direction in different areas of the tunnel can be measured through the tunnel wind speed and wind direction detector, so as to understand the difference in the impact of different designs and materials on the air flow. This can help designers optimize tunnel structures and materials to improve tunnel ventilation and safety.

4. Fire prevention: The underground tunnel is the main carrier of traffic, and there are a large number of flammable materials, such as vehicles and fuel. When the tunnel wind speed and direction detector detects the abnormal air flow in the building, effective emergency measures can be taken in time to prevent the occurrence of fire or reduce the harm of fire.

In summary, tunnel wind speed and direction detector plays a very important role in tunnel construction, operation and maintenance. It can measure the wind speed and direction in the tunnel in real time and accurately, helping managers to adjust and control tunnel safety and ventilation, optimize tunnel design and prevent tunnel fires.
