VERIFICATION OF SAVING ENERGY EFFECT BY ROAD TUNNEL VENTILATION CONTROL SYSTEM BASED ON KNOWLEDGE ENGINEERING AND FUZZY THEORY

The purpose of tunnel ventilation control is to ensure that the concentration of pollutants does not exceed a prescribed level and that the ventilating equipment is operated with minimum power consumption. Previously, a quantitative mathematical model was used for ventilation control systems. With a conventional system, though, it was difficult to attain optimum control with minimum power consumption because of a number of uncertain factors, such as the turbulent flow of air and emission of pollutants from vehicles in the tunnel. To solve this problem, the authors developed a new ventilation control system by applying knowledge engineering and fuzzy techniques in combination. To verify the effect of the system, a 14-day actual ventilation operation was initiated for the knowledge engineering model and the conventional model. The following effects were confirmed: 1) the system can maintain the visual indication values in the target range; 2) the system can reduce power consumption cost by more than 30 percent; and 3) the system can realize proper ventilation for a safe, comfortable driving environment. This paper introduces the system and provides analysis of the actual data results.
