基于单片机 汽车转向灯 汇编语言实现

摘要

随着社会的发展，汽车逐渐成为现代社会的一种重要交通工具。道路上到处都是飞速的汽车。如何保证行人安全，一直都是人们关注的重心。要减少交通事故，就得从汽车的各种安全设计考虑，这不仅仅是汽车本身的质量问题，还应关注汽车在行驶过程中对路人的引导指示方面。其中汽车的各种灯就是安全警示的一个方面，汽车的转弯灯、头灯、尾灯和警示灯等能够帮助路人识别汽车的动向，尤其是当遇到紧急事件时，打开紧急开关就可以警示路人该车现在不安全了，需要小心避车。

汽车在驾驶时有左转弯、右转弯、刹车、合紧急开关、停靠等操作。在左转弯或右转弯时，通过转弯操作杆应使左转开关或右转开关合上，从而使左头灯、仪表板左转弯灯、左尾灯或右头灯、仪表板右转弯灯、右尾灯闪烁；合紧急开关和汽车刹车时，均有相应的信号灯闪烁。本文中汽车转向灯设计是用单片机来实现的，单片机控制系统可避免传统的缺点，因为单片机功能强、使用灵活、可靠性高、成本低、体积小、面向控制、具有智能化功能等很多优点。

Abstract

With the development of society, the car is becoming an important means of transport in the modern society. Rapid car on the road everywhere. How to ensure the safety of pedestrians, has always been attention to the center of gravity. To reduce traffic accidents, you have to consider a variety of safety design of the car, this is not just the quality of the car itself, should also be concerned about the car in the process of moving the boot of the passers-by directives. All kinds of lights of the car is one aspect of security alerts, the car's cornering lights, headlights, taillights, and warning lights to help passers identify cars movements, especially when an emergency event, open the emergency switch can alert passers-by unsafe in the car now, need to be careful to avoid the car.

Car while driving a left turn, right turn, brake, or emergency switch, dock operations.When turning left or right turn by turning the lever to make the turn left switch or right switch is closed, so that the left headlight, dashboard left turn light, the left taillight or right headlights, dashboard turn right light, rightthe tail lights flashing; together an emergency switch and automotive brakes, have the lights flashing. Car turn signal design in this article use the microcontroller to achieve single-chip control system to avoid the traditional shortcomings of the microcontroller functions, the use of flexible, high reliability, low cost, small size, for control, with intelligent features and many other advantages.

Keywords：monolithic integrated circuits ； the car turned the light signals ； basic techniques of digital circuit ； electronic
