文档介绍：自动晾衣架控制系统设计
摘要
智能自动晾衣架能够实现晾衣架的自动升降,衣服超重的自动检测及系统故障保护等功能。与传统的手动晾衣架相比,自动晾衣架具有升降更省力,升降速度更快等优势,随着技术的日臻完善,自动晾衣架将成为市场的主导产品。
本设计采用单片机AT89C51作为自动晾衣架的检测及控制核心,采用电阻应变片实现超重检测,通过手动按键控制晾衣架的升降,通过发光二极管显示晾衣架的工作状态,同时具有超重声光报警作用,该系统还增加了直流电机的的过流保护功能以及电气隔离功能。软件部分采用模块化设计思想,编制了各个模块的流程图,实现了对晾衣架升降控制,状态显示等功能。本设计具有灵活方便、适用范围广的特点,基本能够满足实践需求。
AUTOMATIC CLOTHES HANGER CONTROL SYSTEM DESIGN
ABSTRACT
Intelligent automatic clothes hanger which is able to realize automatic lift the clothes hanger, automatic detection clothes are overweight or not, system's fault protection function of the clothes hanger. Compared with the traditional manual clothes hanger, it has lifting more easily and more faster. As technology is being perfected, automatic air clothes tree will be the market leading products.
This design use the single-chip puter AT89C51 as automatic clothes hanger detection and control core .using resistance strain gauge realize overweight detection, through manual buttons to control clothes hanger up or down. through the leds to display the clothes hanger working the same time,it has the overweight sound-light alarm circuit. this system also increased dc motor of the over-current protection part adopts modular design thought, compiled the flowchart of each module. realized to dc motor positive & reverse control and state display design is agile and convenient, widely use .Basicly can satisfy the practice demands.
