基于Zigbee技术的城市轨道交通客流检测系统的设计

摘要

This paper makes some research on the working principle of air springs of urban rail transit vehicles, analy zes the calculating method of train passenger capacity and proposes the design scheme of urban rail transit passenger flow volume detecting system. Through the acquisition of the internal pressure values of air springs, the train capacity can be calculated. By using Zigbee technology for achieving data transmission between trains and ground stations and e ventually transporting by the Ethernet to the passenger flow analysis server, the real-time monitoring of urban rail transit passenger flow can be achieved.%对城市轨道交通车辆空气弹簧的工作原理进行了研究,分析了列车载客量的计算方法,并提出城市轨道交通客流检测系统的设计方案.通过采集空气弹簧的内压值来计算列车的载客量,采用Zigbee技术实现车地数据传输,最终由以太网传输到客流分析服务器,实现对城市轨道交通客流的实时检测.
