摘要
为了解决对高速公路上汽车速度的测定以及对汽车流量的统计这一问题,本文设计并实现了一种高速公路监控系统。本系统以线阵CCD作为前端检测装置,以ARM微处理器作为中心信号处理装置,以U盘作为交通信息存储装置,具有测速精度高、系统实时性高以及使用方便等优点。同时借助于LCD和GUI,本系统实现了监控结果的直观显示,从而拥有一个友好的用户界面。实验表明,本系统的测速误差不超过2%,具有很高的测速精度,可用在多种多车道的高速公路。
The new design of traffic monitoring system, which provides solutions to calculate the speed of a vehicle and monitor the traffic flow on speedways, is put forward in this paper. Equipped with linear CCD image sensor, ARM micro controller and U disk, this system has many features, such as high system precision, high response, and convenient use. Besides, it integrates LCD and GUI for displaying working status and so it has a friendly user interface. The experiment shows that the speed error of this system is no more than 2%, so the system has a very high precision and can be used on many kinds of speedways with multi driveways.
