摘 要

在我们的日常生活中，汽车已经成为不可或缺的一部分，大量的的人拥有汽车带来的便利，但同时也产生了一系列社会问题。汽车丢失，汽车保养等让有车一族大为头疼，如何保证停车，不让爱车丢失是一个社会问题。更加让车库门控制器设计拥有实际意义。

这次车库门控制器基于单片机设计，实现车库门自动开关，按键密码输入控制，数码管显示密码等。车库门控制器设计内容包括绪论、方案讨论、硬件设计、软件设计设计。以STC12c5608AD单片机为核心，配上按键模块、数码管显示模块、电机控制模块，运用Altium designer软件进行原理图设计，绘制PCB图进行制版。软件设计方面分为键盘扫描模块、数码管显示程序模块、按键查询程序模块、I²C 总线模块、电机控制程序模块等几个模块组成，从而完成车库门控制设计。

Garage door controller design

ABSTRACT

In our daily life, cars have become an integral part of a large number of people have to bring convenience to the car, but also produced a series of social problems. Missing car, car maintenance, make car owners a headache, how to ensure the parking, don't let the car lost is a social problem. More to let the garage door controller design has the practical significance.

The garage door controller based on single-chip design, to achieve automatic garage door switch, key password input control, digital tube display password, etc.. The design of garage door controller includes hardware introduction, scheme discussion, hardware design, software design and hardware design. With STC12c5608AD microcontroller as the core, with the button module, digital tube display module, motor control module, the use of Altium designer software schematic design, drawing PCB chart for plate making. Software design points for the keyboard scan module, digital tube display key module procedures, query module procedures, I2C bus module, motor control module program, and several other modules, thus completing the garage door control design.
