公路隧道通风控制系统的研究

Research of Tunnel Ventilation Control System on the Highway

通风系统是长大公路隧道的重要组成部分。将隧道内有害气体及粉尘浓度控制在容许限度之内,是通风控制的目的。通过传感器采集隧道内有害气体及粉尘浓度,并将主要的控制参数传递给上位机,一旦超标就启动声光报警和风机换气。考虑到节能的问题,将变频调速技术应用到隧道通风控制中。

The ventilation system is the most important components of long road tunnel. The thickness of harmful gases and dust in the tunnel should be controlled within the pemisive limits of system and this is the main purpose of the ventilation system of control. The system can collect the information of thickness of hamful gases and dust in the tunnel through the sense organ and send the primary control parameters to the PC. It will give an alarm using voice and light and exchange the air by the fans once the parameters exceed. Considering the issue of energy conservation, VVVF technology will be applied in the tunnel ventilation control.
