摘要

为了保障高速公路的行车安全，介绍了一种基于ZigBee无线通信技术下的高速公路限速系统，系统采用无线传感网络对高速公路周围的温度、湿度及可吸入颗粒物浓度等环境参数进行实时检测，并采用无线组网技术和ARM嵌入式技术主动控制车辆车速，保障了高速公路对行车的限速要求；在数据处理方面采用卡尔曼滤波算法并同时将有关数据实时显示在上位机上.仿真实验表明，通过拟合后的数据曲线比较平滑，提高了数据判断的可靠性，实现了车辆的主动限速控制.

Abstract

In order to ensure road safety of highways

the paper introduces a system based on ZigBee highway speed limitation.The system uses wireless sensor networks to detect the environment temperature

humidity

and inhalable particles matter concentration data near highways.The system uses wireless networking technology and embedded technology to achieve the highway speed limitation

Using Kalman filtering algorithm to do curve fitting for monitored environmental data for real-time display on monitoring interface of upper computer.Simulation shows that the system is running under excellent condition.The fitted data turn out an ultra enhancement in smooth and reliability.Initiative to achieve a vehicle speed control.
