由于科学技术的发展人们的生活水平得到提升,日常生活中越来越多的应用洗衣机,在人们日常生活中,到处都可以看到洗衣机,在自动化领域控制的主要有微机控制,PLC控制以及继电器控制,早期的继电器洗衣机主要是硬件控制的,不利于洗衣机稳定的工作,PLC自动洗衣机有程序控制功能,有利于系统的性能提升,也能够进行系统的维修,本文的实际结构主要是PLC工业洗衣机,我们通过分析PLC洗衣机的系统原理,结合PLC的IO分配表以及程序流程图,最终很好地对系统进行控制和设计。
As the development of science and technology people’s living standards have been improved, more and more daily use of washing machines, people in everyday life, washing machines can be seen everywhere, mainly in the field of automation computer control, PLC control and relay control Early relay washing machine is mainly hardware-controlled, is not conducive to the stable operation of the washing machine, PLC automatic washing machine program control function is conducive to the performance of the system to upgrade, but also to system maintenance, the actual structure of this paper is mainly PLC industrial washing machines, Through the analysis of PLC washing machine system principle, combined with the PLC IO distribution table and the program flow chart, the final control of the system and design.
