随着人们对车库门要求的提高,车库自动门开始出现。控制系统是车库自动门设计的关键,本文就是基于单片机的车库自动门控制系统设计,设计包括硬件和软件两个部分。硬件部分选用AT89C51单片机作为主控芯片,同时设计一个最小系统使单片机能够正常工作。软件部分主要是用C语言编程的,自动门程序包括三个部分,主程序、自动模式门运行程序和手动模式门运行程序。 As people demand higher garage doors, automatic garage doors began to appear. Control system is the key to automatic garage door design, this article is based on single-chip garage automatic door control system design, including hardware and software design of two parts. Hardware selection AT89C51 microcontroller as the main control chip, while designing a minimum system so that the microcontroller can work properly. Software part is mainly C language programming, automatic door program includes three parts, the main program, automatic mode door operation procedures and manual mode door operation procedures.
