摘要
为解决驾驶员从隧道外部进入隧道内部的眼睛对光照亮度的适应问题,提高驾驶的安全性,设计通过STC12C5A60S2单片机控制光强采集模块BH1750实时采集外部环境光强,将数据经过NRF24L01无线方式发送、接收,PT4115驱动LED发光的方法,实现了基于单片机的隧道灯控系统的设计。系统包含有一个主机和4个分机,最终实验测试结果表明,本设计能较好的实现测量隧道外部的光强来控制LED发光强度,从而使得内部的亮度随着外部的亮度渐变的功能,具有一定的实用性和创新性。
In order to solve brightness adaptation problems of driver go into tunnel＇s interior from the outside,improve driving safety,a feasible scheme is given by this paper.It uses BH1750 to acquire real-time light intensity of tunnel＇s outside,along with,used NRF24L01 to send and receive data,and uses PT4115 to drive LED.The system includes a host and four extension,the final test results show that this design can achieve better measurement of tunnel external light to control the LED light intensity,thus making the internal brightness with the brightness gradient outside the function,has certain practical and innovative.
