基于Proteus的MCS-51仿真
－汽車(chē)轉(zhuǎn)變信號(hào)燈仿真

摘 要
在我國(guó)工業(yè)化進(jìn)程中，以單片機(jī)應(yīng)用為主的嵌入式系統(tǒng)對(duì)國(guó)民經(jīng)濟(jì)的發(fā)展起到重要的推動(dòng)作用。單片機(jī)由于控制功能強(qiáng)、可靠性高和體積小、價(jià)格低等特點(diǎn)。在智能儀器儀表、工業(yè)測(cè)控、家用電器等領(lǐng)域有非常廣泛的應(yīng)用。
本設(shè)計(jì)利用嵌入式系統(tǒng)和仿真技術(shù)，完成了一個(gè)汽車(chē)轉(zhuǎn)變信號(hào)燈系統(tǒng)仿真工作。硬件設(shè)計(jì)部分主要由AT89C51芯片、LED顯示以及其他輔件等組成。軟件設(shè)計(jì)是依據(jù)現(xiàn)代汽車(chē)系統(tǒng)的特點(diǎn)，通過(guò)Proteus 和KEIL聯(lián)調(diào)，使得系統(tǒng)除具有基本的緊急，剎車(chē)，右轉(zhuǎn)彎，左轉(zhuǎn)彎，停靠功能外，還具有左轉(zhuǎn)彎時(shí)剎車(chē)，右轉(zhuǎn)彎時(shí)剎車(chē)，左轉(zhuǎn)彎時(shí)剎車(chē)閉合緊急，右轉(zhuǎn)彎時(shí)剎車(chē)閉合緊急，剎車(chē)時(shí)緊急等功能。

Simulation of the MCS-51 based on Proteus
－Simulation of Signal changes in vehicle

Abstract
In the process of the industrialization, the embedded system, most of which are single chip computers, boost the economic development of our country. Mcu due to control function, high reliability and low cost, small volume. In the intelligent instrument and industrial control, household appliances and other fields have a very wide range of applications.
This design using the embedded system and simulation technology, completes a car for system simulation signal transformation. The hardware design is mainly composed of AT89C51 chip, LED display and other auxiliary parts etc. Software is designed according to the characteristics of modern automobile system, through KEIL and Proteus. The system has some function, for example, emergency, brake, right turn, left turn, call functions, also have left turn when the brakes when the brake and turn right, turn left closed when the emergency brake, and turn right when the closure of emergency braking, emergency braking and other functions.
