基于單片機的電子車窗控制器的設計


摘要：本文主要討論了單片機在汽車車窗控制系統(tǒng)的應用，在實時控制系統(tǒng)中廣泛應用的通斷控制方式來實現(xiàn)對電動機的轉動控制。將單片機技術和傳感器技術結合起來，詳細介紹了硬件電路的設計原理和軟件的編寫過程。在整個硬件系統(tǒng)中，主要是以AT89C51單片機為控制中心，系統(tǒng)驅動模塊、傳感器檢測模塊、電動機控制轉動模塊等三大模塊并對這三大模塊加以詳細的介紹。在軟件設計方面，實現(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.
