[Abstract]:In the 12th Five-Year Plan, a safe and efficient transportation service system is of vital importance to people's livelihood and economy.The efficient operation system of highway tunnel is also improving continuously, no matter from safety or energy saving, it is necessary to study.Based on the Swire Xishan Tunnel, aiming at the direction of ventilation control system of highway tunnel, this paper overcomes the hysteresis and multi-parameter control difficulty caused by nonlinear control system, and discusses how to efficiently discharge the pollution of tunnel (main smoke COVisibility).How to realize the control strategy of fan start and stop in tunnel, the research and control method of the above problems are put forward.This paper is divided into the following four aspects: first, the study of the relevant models of highway tunnel ventilation control system, including the change of pollutant dynamics model, traffic flow model, determine the structure and objectives of the CO/VI air volume control system, secondly,The control structure and model of this project are analyzed, the necessity of traffic forecast is explained, the forecasting method based on wavelet neural network is determined, and the method process and reference index are briefly described.Finally, the fuzzy controller of tunnel ventilation control system is designed with actual value and controller target setting deviation value, combined with traffic volume, feedforward control and so on, after fuzzy principle inference, the fuzzy controller of tunnel ventilation control system is designed.Simulation shows the reliability of the design, determines the number of output fan start and stop control. Finally, the simulation platform level is established, and the experimental research of highway tunnel ventilation control system based on fuzzy control is realized by both software and hardware.Software STEP7V5.5, Kingview, hardware is CO/VI sensor, industrial control computer S7-300 PLC, jet fan and so on, real-time monitoring control effect on the upper computer.The results show that this paper applies wavelet neural network and fuzzy control principle to the ventilation control system of the highway tunnel at the same time.The ventilation control system not only has a strong learning advantage, but also can overcome the nonlinear and lag defects of practical control. Through the combination of theory and practical engineering, it basically meets the requirements of safe ventilation and energy optimization.It shows that this study has practical significance.
