基于单片机的LED车灯及仪表控制设计与实现

The Design and Achievement about the LED Headlight of an Automobile and Instrument Control Based on Single Chip Microcomputer

文章分析了LED车灯及仪表控制系统网络的设计要求,在明确汽车灯光种类及各种控制要求的基础上,对利用单片机多机通信方式实现LED车灯及仪表控制系统网络化控制进行了研究,设计了硬件电路图及主、从机程序。车灯的外观设计力求模拟真车,技术控制利用单片机的多机通信原理,在模拟仿真的基础上用6块万能板制作出基于单片机多级通信的LED矩阵车灯及仪表控制系统网络,将万能板安装在车模上仿真真车的灯光运行,此成果可作为汽车类各专业课程的教具。

This paper analyzes the LED headlight of automobile and the design requirements of instrumental control system network.On the basis of explicit types of automobile headlight and various control requirements and the study of using single chip computer about multi-machine communication mode to realize LED headlights and networked control about instrumental control system,the paper designed the hardware circuit diagram and the program of master and slave machine. The appearance design of headlight seeks to simulate a real car. The control technology uses multi-machine communication principle of single chip computer.On the basis of the simulation to produce a LED array lights with 6 universal boards and the instrument control system network based on multi-level communication about single chip microcomputer. The universal boards are installed on the car model and simulate a real car running lights. This results can be used as teaching AIDS in motor vehicles of various professional courses.
