CONTROL APPARATUS AT FIRE OUTBREAK IN TUNNEL

摘要

PROBLEM TO BE SOLVED: To perform sufficient air speed control in the vicinity of a fire outbreak location in consideration of the starting timing of a ventilator near the fire outbreak location and also that of a ventilator located at a place distant from the fire outbreak location.SOLUTION: A control apparatus at fire outbreak in tunnel comprises: storage means; first calculation means; and second calculation means. The storage means stores set data of weighting factors representing a degree of effect of variation in air speed in driveways of ventilation sections except a fire outbreak ventilation section on the fire outbreak ventilation section. The first calculation means calculates the degree of effect on the fire outbreak ventilation section when controlling so as to suppress the air speed in the driveway of the fire outbreak ventilation section on the basis of the read set data. The second calculation means calculates the air speed in the driveway of each of the ventilation sections such that the calculated degree of effect becomes a preset target value.
