摘要
针对单向交通的公路隧道采用射流风机进行纵向通风的特点 ,提出了采用神经网络在线控制的方法。利用该方法建立隧道通风在线控制模型 ,并结合空气动力学模型、污染模型及交通模型进行了隧道纵向通风过程的动态模拟仿真。结果表明 。
The paper postulates a method of the online control of neural net in accordance with the features of the longitudinal ventilation using jet ventilators for highway tunnels with one direction traffic. An online control model of tunnel ventilation is established based on the method, upon which a dynamic simulated emulation of the process of longitudinal tunnel ventilation is carried out incorporating the model of aerodynamics and the model of contamination. It is shown that good results can be obtained by using the online control of the neural net for the longitudinal ventilation of highway tunnels.
