基于單片機(jī)的電子車窗控制器的設(shè)計(jì)


摘要：本文主要討論了單片機(jī)在汽車車窗控制系統(tǒng)的應(yīng)用，在實(shí)時(shí)控制系統(tǒng)中廣泛應(yīng)用的通斷控制方式來實(shí)現(xiàn)對電動機(jī)的轉(zhuǎn)動控制。將單片機(jī)技術(shù)和傳感器技術(shù)結(jié)合起來，詳細(xì)介紹了硬件電路的設(shè)計(jì)原理和軟件的編寫過程。在整個(gè)硬件系統(tǒng)中，主要是以AT89C51單片機(jī)為控制中心，系統(tǒng)驅(qū)動模塊、傳感器檢測模塊、電動機(jī)控制轉(zhuǎn)動模塊等三大模塊并對這三大模塊加以詳細(xì)的介紹。在軟件設(shè)計(jì)方面，實(shí)現(xiàn)了數(shù)據(jù)的采集、處理和控制。

Design of electronic window Based on Microcomputer


Abstract: This paper mainly discussed the single-chip microcomputer in the vehicle window control system. Mainly in the real-time control system it is widely used in on-off control mode to achieve the rotation of the motor control. The single-chip technology and sensor technology combined with detailed hardware and software design principle of the preparation process. In the entire hardware system, and it is based on AT89C51 single-chip microcomputer to control the center, the system drive module, sensor detection modules, motor control modules, such as rotation of the three modules to the three modules in detail. In software design, the main module of sensor detection, motor control module designed to rotate in order to achieve the data collection, processing and control.

Key words: microcomputer; current sensor; window control
