【摘要】 本文研究来自于智能交通项目车辆流量检测系统,该系统以嵌入式多任务操作系统为平台,采用Zigbee2006协议栈组成的无线Zigbee网络车辆流量数据采集系统。该车辆数据采集系统分为上位机控制和下位机控制两大部分,通过上位机软件能对任意节点参数进行设定,所控制对象对控制结果进行反馈和发送数据;能够对每一时刻的车辆流量、车辆速度、当时温度、道路利用率等数据进行检测采集;数据库能对系统的温度、安装位置、车辆流量信息等进行保存和处理。更多还原

【Abstract】 A traffic flow data acquisition system of intelligent transportation project based on Zigbee wireless networks is studied in this paper,which adopts embedded multi-tasking operating system and Zigbee 2006 Stack.The vehicle data acquisition system is composed of two parts--master module and slave module.With the help of PC software,the node parameters can be set,the controlled object can feedback the control signals and send data.The vehicle flow,vehicle speed,temperature,utilization rate of road and other data can be collected efficiently at any time,and the system temperature,the installation location,traffic flow information can be stored and handed into the database.更多还原
