摘 要
自動關窗器是針對現(xiàn)代轎車中沒有安裝自動關窗系統(tǒng)的車而設計的。本設計是為了預防車主在熄火停車后忘記關窗，造車車內(nèi)物品丟失，或者因為雨天或者其他天氣原因而造車車內(nèi)進水或進入其它異物而造車不必要的損失。
本次設計主要是針對威馳轎車的電路進行設計。一開始闡述了威馳轎車自動關窗器的設計目的及意義、及應用。接著分析了設計的基本內(nèi)容及要解決的相關的問題。本方案通過對威馳轎車的原有電路進行分析，在原電路基礎上進行設計通過添加一些相應的電子元件。進行對威馳轎車的熄火停車后的關窗系統(tǒng)進行控制控制。還對怎樣選擇合適的三極管，繼電器以及電路保護裝置做了簡單的介紹。
本設計基于AT89c51單片機進行程序設計。對于單片機的原理，各個引腳的作用以及控制方式等做出了簡單的介紹。最后搭建具體電路來驗證該設計方案的可行性。

ABSTRACT
The automatic window controller is designed for the modern car which didn’t intall the system for self-closing the window. This design is for a preventive against missing items in the car or other reasons like raining into the car cause unnecessary losses as the owner forget to close the window afer parking.
The design is based on the circuit of vios. At first elaborate the significance purpose and application for the automatic window controller. Next analysis the substance of this design and associated problems need to solve. This scheme analysis of the circuit of vios and add other electronic components to original circuit aim at controlling the system for self-closing the window after parking the car. It also make a simple introduction for how to choose a proper transistor relay and protecting device of circuit.
This design based on the AT89c51 SCM（Single Chip Micyoco）,make a introduction for the principle of SCM the effect and control about each pin. At last set up a specific circuit to verification the feasibility of the design.
