单片机课程设计报告—遥控窗帘.doc

河南理工大学 《单片机应用与仿真训练》设计报告 基于单片机的遥控窗帘设计 成 员： 朱学政 专业班级： 电仪09-3班 指导老师： 王莉 　　　 所在学院：电气工程与自动化学院 2012年6月25日 摘要 随着电子技术和自动化技术的发展，人们对生活质量的要求越来越高。家用电器产品也在不断的更新换代。从始初的晶体管到电子管；由模拟到数字；由分立元件到集成电路；从普通向高性能、多功能型；由手动控制向红外线遥控、向智能化发展。此次设计的是智能家居必备智能装置之一——遥控窗帘。它是采用AT89S52单片机为控制核心，可遥控、可手动控制窗帘的拉开和关闭。 这里介绍了基于单片机技术的遥控窗帘的设计原理，给出了控制电路和执行模块的硬件设计方案，以流程图方式对本系统的控制和执行的软件设计进行了较为详细的介绍，并制作出了实物模型。该系统的控制部分主要由键盘扫描电路、单片机（AT89S52）最小系统、行程开关及电动机驱动控制电路等组成；窗帘控制部分主要由导轨、窗帘、拉绳和步进电机等组成。单片机根据接收到的不同信号来控制电动机的正转、反转或停止，从而实现窗帘的打开、关闭或停止。 关键字：遥控窗帘； AT89S52； Summary With the development of electronic technology and automation technology, people increasingly high demand for quality of life. Household products are constantly upgrading. To the tube from the beginning of the beginning of the transistor; from analog to digital; from discrete components to integrated circuits; from the ordinary high-performance, multi-functional; manual control to the infrared remote control, to the intelligent development. The design is necessary intelligent smart home devices - one remote control curtains. It is AT89S52 MCU core control, remote control, you can manually control the curtains opened and closed. Here are the design principles based on single-chip technology, remote control curtains, control circuit and the implementation of the modules hardware design, a more detailed introduction to the form of a flowchart of control of the system and implementation of software design, and produce physical model. The control part of the system mainly by the composition of the keyboard scanning circuit, microcontroller (AT89S52) minimum system, limit switch and the motor drive control circuit, etc.; curtain control part by the composition of the rails, curtains, rope, and stepper motor. The microcontroller according to the received signal to control the motor forward, reverse, or stop in order to achieve the curtains open, close or stop.
