基于C8051F121在智能车辆检测器中的设计与应用

A design and application of intelligent vehicle detection device based on C8051F121

随着我国城市道路交通的发展,汽车数量不断上升,使得城市交通拥挤和交通事故日显突出,为了能够改善混乱的交通状况,缓解道路拥堵、改善出行条件、提高运输效率、提高道路安全性,为此,人们提出了智能车辆检测器,以此来解决日益突出的交通问题。本文基于美国Silicon Lab公司的CIP-51TM微控制器核的片上系统(SOC)C8051F121芯片为核心的硬件平台,文中对设备的硬件电路设计,接口电路设计和软件设计进行全方面的论述和研究。实验结果证明该设备具有低功耗、低成本、功能强大的特点,充分利用了该芯片提供的资源,并且满足了智能车辆检测器的需求。

With the development of city traffic, the number of automobile owners is soaring, resulting in more and more traffic jams and traffic accidents. In order to improve the situation of traffic disorder, ease traffic congestion, improve traffic condition, enhance transportation efficiency and raise safety the intelligent vehicle detection device has been put forward. The article has discussed and researched to hardware circuit, interface circuit and software design based on the core of C8051F121 chip of Silicon Lab＇s CIP51TM SOC. The result of the experiment prove this device have the specialty of low consumption, low cost, powerful function, make full use of resource provided by this chip, and satisfied the necessity of intelligent vehicle detection system.
