一种新型自动化弯道道路交通信号提示系统

A New Type of Automated Curved Road Traffic Signal Hinting System

在山区公路转弯或市区繁华路段的弯道,常因无法判断前方是否有车辆通过而事故频发。本文所涉及的新型自动化弯道道路交通信号提示系统利用的是放在弯道道路两侧的超声波测距仪予以识别,根据不同等级的弯道设置相应的测距仪间隔,并通过c52单片机进行数据处理,并将车辆的速度、长度以及车辆距离弯道处的距离识别出来,并通过数据分析与整合,将得到的信息传递到下一级c51单片机中。该单片机对信息进行整理后将数据信息通过控制LED灯亮的个数展示出来。为了让司机能够更加直观地了解到来车的距离,我们用一排LED灯来提示。LED亮的越多,代表来车距离转弯处的距离越近。同时在供电环节,采用市电互补清洁能源发电系统供电。实现经济性、环保性及节能性。

In the turning of mountain roads or curved roads in ur-ban areas, accidents are frequent because drivers can not deter-mine whether there are vehicles in front of them. The new type ofautomated curved road traffic signal hinting system introduced inthis paper is to identify vehicles using the ultrasonic range finderslocated on both sides of a curved road. An appropriate rangefind-er interval is set in accordance with different levels of curvedroads, and c52 single-chip microcontroller is used to carry outthe data processing. It means that the speed and length of vehi-cles as well as their distances from the corner are identified.Through data analysis and integration, the information ob-tained will be passed to the next level single-chip c51 micro-controller which will rearrange the information and show thedata information by controlling the number of LED lights. Inorder to allow drivers to have a more intuitive understanding oftheir distance from the coming vehicles, we usea row of LEDlights to prompt them. The more LED lights are, the closer is thecoming vehicle. In terms of power supply, the electricity comple-mentary clean energy power is used, which is economical, envi-ronmentally friendly and energy-efficient.
