い問題であった。DETAILED DESCRIPTION OF THE INVENTION Field of Application of Ai2 The present invention relates to ventilation and lighting control in a road tunnel.6 Prior Art A conventional ventilation and lighting control in a road tunnel is shown in FIG. As such, lighting control and ventilation control, which greatly influence the visibility inside the tunnel, were completely independent. In other words, conventional ventilation control uses the smoke permeability inside the tunnel (hereinafter referred to as rVIJ) 1, CO2, and wind direction and wind speed 3 as measurement elements, and among these, the optimum notch is determined mainly based on the visibility condition inside the tunnel according to VII. In most cases, ventilation was controlled5 to increase or decrease the amount of ventilation. As a result, even if full ventilation is implemented immediately in response to a sudden deterioration of visibility inside a tunnel, it takes 5 to 10 minutes for the ventilation effect to appear, and in long tunnels it takes longer than that. In short, the delay in response became a drawback. Furthermore, in conventional lighting control, only the illuminance or brightness 6 at the tunnel entrance is adjusted to H1'l.
The main purpose is to prevent driver dazzling by determining the optimum notch (7) and controlling the lighting (8) by increasing the number of lights near the tunnel entrance.Inside the tunnel, only basic lighting at the lowest level of illumination is used, and the above-mentioned method is used. In response to sudden deterioration of visibility, ventilation is the only response, and the effects of ventilation and delayed response may impede safe vehicle driving and may cause vehicle accidents, fires, and secondary disasters. That was a problem.

The illuminance or brightness inside the mine is added as a measurement element for lighting control, the smoke transmittance inside the mine and the illuminance or brightness inside the mine are added as measurement elements for lighting control, and the ventilation control and lighting control are combined to control ventilation and lighting. It performs simultaneous control.

Simultaneous ventilation and lighting control can be performed by mutually combining ventilation control and lighting control so that the delay in response is compensated for by increasing the illuminance and the illuminance is reduced when the ventilation effect is achieved.
