建立了人流密度-速度模型,采用软测量技术形成基于LS-SVM支持向量机的智能疏散诱导算法。通过智能疏散诱导系统对疏散指示灯的PWM控制,实现了疏散路径的动态调整与优化,给出了动态疏散路径的标识方法。试验结果表明,智能疏散诱导系统能够缩短疏散时间,提高疏散效率。

A model of the personnel density-velocity was established. Based on the LS-SVM, the intelligent evacuation guidance algorithm was proposed by using the soft-sensing technique. The intelligent evacuation guidance system controlled the stroboscopic cycle of evacuation indicator lamps to complete dynamic adjustment and optimization of evacuation routes by PWM. A method of dynamic evacuation paths was given. The experimental results show that the method reduces the evacuation time and improves the evacuation efficiency.
