制御装置。 Ventilation fans installed in the twin tunnels connected by evacuation tunnels, smoke transmittance measurement devices and carbon monoxide measurement devices installed in the tunnel, and the detection device signals determine the condition inside the tunnel and provide ventilation. In the tunnel ventilation control system, which consists of a control computer that operates the machine, the barometers installed in both tunnels are used to compare the atmospheric pressure values of both tunnels during abnormal operation such as a fire, and check whether the tunnels are healthy or not. Equipped with a ventilation fan control function that controls the ventilation fan of the healthy side tunnel so that the internal pressure of the side tunnel is high, it prevents smoke from flowing into the healthy side tunnel through the evacuation shaft and improves the evacuation route. Tunnel ventilation control device characterized by ensuring.
