摘要

本次论文主要利用AT89S52单片机模拟汽车尾灯进行智能控制的控制器，用8个LED灯模拟汽车尾灯，6个独立按键分别对应了右转、左转、危险警示、夜间模式切换、检查信号、刹车不同的状态，在实际设计模拟电路中，我加入了74HC595芯片，减少了使用51单片机的I/0口的使用，在复杂的电路中，这是一种很好的方式实现一种芯片控制多个不同电路的优点。在实际设计模拟汽车尾灯控制电路中，了解了LED驱动电路特性，提出相应解决方案，进行可靠性的设计。在这次设计模拟汽车尾灯控制电路，能很好的综合运用我们在课程中学习到的51单片机的功能与运用，还有C语言编程，模拟电子电路基础，以及数字电路基础，在实际应用中，有许多种方法设计汽车尾灯的控制，在本次设计模拟电路中，我用的是AT89S52单片机作为整个电路的设计核心来控制整个电路的模拟功能，整个电路变的简单、直观，制作方便，而且容易操作，51单片机可反复擦写，性能可靠等优点。

Abstract

In this paper,Simulation this paper mainly use AT89S52 car taillight controller of intelligent control, with eight car tail lights, LED lights simulation six independent keys corresponding to turn right, turn left, risk warning, night mode, check the switch signal, brake different state, in the actual design analog circuits, I joined the 74 hc595 are needed chip, reduce the use of 51 single-chip microcomputer I / 0 interface to use, in a complex circuit, it is a good way to realize the advantages of a different circuit chip control. In the actual design automobile tail light control circuit simulation, know the LED driver circuit characteristics, put forward the corresponding solution, the reliability design. Simulation in the design automobile tail light control circuit, can be a very good combination of we learned in the course of function and use of 51 single-chip microcomputer and the C language programming, analog electronic circuit, and digital circuit basis, in practice, there are many ways of design automobile tail light control, in the analog circuit design, I am using AT89S52 as the core to control circuit design of the circuit simulation function, the whole circuit is simple and intuitive, and convenient, and easy to operate, 51 single-chip microcomputer can wipe again and again, the advantages of reliable performance.

Keywords: AT89S52, 74 hc595 are needed, LED lights, car tail lights, C language
