基于Proteus的MCS-51仿真
－汽車轉(zhuǎn)變信號燈仿真

摘 要
在我國工業(yè)化進程中，以單片機應用為主的嵌入式系統(tǒng)對國民經(jīng)濟的發(fā)展起到重要的推動作用。單片機由于控制功能強、可靠性高和體積小、價格低等特點。在智能儀器儀表、工業(yè)測控、家用電器等領域有非常廣泛的應用。
本設計利用嵌入式系統(tǒng)和仿真技術(shù)，完成了一個汽車轉(zhuǎn)變信號燈系統(tǒng)仿真工作。硬件設計部分主要由AT89C51芯片、LED顯示以及其他輔件等組成。軟件設計是依據(jù)現(xiàn)代汽車系統(tǒng)的特點，通過Proteus 和KEIL聯(lián)調(diào)，使得系統(tǒng)除具有基本的緊急，剎車，右轉(zhuǎn)彎，左轉(zhuǎn)彎，停靠功能外，還具有左轉(zhuǎn)彎時剎車，右轉(zhuǎn)彎時剎車，左轉(zhuǎn)彎時剎車閉合緊急，右轉(zhuǎn)彎時剎車閉合緊急，剎車時緊急等功能。

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.
