基于PLC的全自动洗衣机毕业设计.docx

湖北工业大学商贸学院毕业设计 I 摘要随着可编程控制器( PLC )在工业控制领域的广泛应用,及传统的控制技术的不断更新。本文依据 PLC 为主要部件设计完成了全自动洗衣机的控制系统。该控制系统的工作流程主要由进水、洗涤、排水、脱水 4 个步骤组成, 在本控制系统中 4 个步骤依次运行直至洗衣结束。所采用的控制方法操作简单、稳定可靠、维护与维修方便。控制方法确定后投入生产要缩短控制系统的设计的时间、调试周期,且要降低成本。根据洗衣机的工作原理从而对程序及其流程进行了设计, 该系统具有智能化程度高、安全可靠和运行稳定等特点。同时本文介绍了全自动洗衣机的控制系统的 PLC 设计方法、程序流程图、系统结构图、程序指令、梯形图等, 实现全自动洗衣过程。在系统资源分配中给出了详细的 I/O 地址分配及辅助继电器, 是程序设计的基础, 设计出的全自动洗衣机控制系统中克服了单片机的缺点,具有 PLC 可靠性高,耗电少,硬件简单,运行速度高等优点。关键词: PLC 自动控制洗衣机湖北工业大学商贸学院毕业设计 II Abstract With the programmable logic controller (PLC) is widely used in industrial control field, and constantly updated traditional control technology. In this paper, the ponents of the design basis for pleted the automatic washing machine control system. The workflow control system is posed of water, washing, draining, dewatering four steps, in the present control system in four steps in sequence until the laundry operation ends. Control method used is simple, reliable, easy to maintain and repair. After determining the control method to shorten production time control system design, debug cycle, and to reduce costs. Meanwhile article describes the design method PLC control system, automatic washing machine, program flow, the system structure, program instructions, ladder, etc. , to achieve automatic laundry process. The allocation of resources in the system are given in detail in the I/ O address assignment and auxiliary relays, is the basis for program design, design a fully automatic washing machine control system to e the ings of the microcontroller, PLC with high reliability, low power consumption, simple hardware, operating speed advantages.
