題目：基于触摸屏控制系统设计 摘 要 本次课题主要介绍基于可编程控制器的变频调速的若干成果，在本次设计中我们的设计系统主要有PLC,变频器，触摸屏，电动机等几部分组成。经过此次设计使我们对所有器件有了新的认识，尤其是对PLC有了更多的了解：它采用一类可编程的存储器，用于其内部存储程序，执行逻辑运算、顺序控制、定时、计数与算术操作等面向用户的指令，并通过数字或模拟式输入/输出控制各种类型的机械或生产过程。可编程控制器（PLC）是以微处理器为核心，将自动控制技术、计算机技术和通信技术融为一体而发展起来的崭新的工业自动控制装置。目前PLC已基本替代了传统的继电器控制而广泛应用于工业控制的各个领域，PLC已跃居工业自动化三大支柱的首位。首先我们查阅各个器件的资料，先对其有个明确的认识，然后通过老师的指点了解整个系统的大概，画出原理图框后将硬件设备连接起来，接着通过学习GX developer 编程软件将所用的设备用程序连在一起，然后调试并最终完成项目。 本次设计综合应用电子学与机械学知识去解决基于可编程控制器的变频调速系统，本次设计选用了三相异步交流电机，而PLC与交流电机无论是在工业还是在生活中都是应用最广的，因此此次设计具有相当的使用价值。 关键词： PLC, 变频器，触摸屏， 电动机，GX developer Abstract This paper mainly introduces some achievements of VVVF based on programmable logic controller, in this design design system we are PLC, touch screen, frequency converter, motor and other parts. Through this design gives us a new understanding on all devices, especially have more understanding of the PLC: it uses a kind of programmable memory, used in its internal storage procedures, to perform the logic operation, sequence control, timing, counting and arithmetic operations such as user oriented instructions, and through digital or analog input / output control all kinds of machinery or production process. Programmable logic controller (PLC) is a microprocessor as the core, the automatic control device that developed the automatic control technology, computer technology and communication technology com. and new industry. At present, PLC has basically replaced the traditional relay control and is widely used in various fields of industrial control, PLC has leapt to the three pillars of the first industrial automation. First, we examine the device information, to have a clear understanding of, and then through the teachers guidance to know about the whole system, draw the principle frame after connecting the hardware devices, and then through the study of GX developer programming software will be used equipment program together, then debug and final completion of the project. The integrated application
