摘　　要：针对目前踩踏事故频繁发生的问题,提出面向移动智能终端的踩踏预防系统.该系统首先利用移动智能终端自身的传感器采集行人在突发事件下的行走数据,然后对行人加速度等信号进行处理,检测和计算行人步频、步长和行走方向.接着调取室内地图并显示在智能终端,直观地显示出用户的位置,最终引导用户疏散.在移动智能终端上进行实验,结果表明,该系统能实时地对突发事件中的行人进行较为准确的定位和疏散引导,从而避免踩踏事故的发生.Aimed at current problem of frequently occurred trample, a mobile intelligent terminaloriented trample prevention system is proposed. In this system, sensors embedded into mobile intelligent terminal proper are used first to gather pedestrian walking data in an emergency. Then the pedestrian acceleration signal is processed, the pedestrian step, frequency, step length, and walking direction are detected and calculated, and further the indoor map is called and displayed in the intelligent terminal and user＇s location will intuitively be displayed therein. Finally, the user is guided to be evacuated. Experimental results show that this system will be able to position the pedestrian in an emergency and guide his evacuation, so that the trample accident will be avoided.
