基于PLC标签打印控制系统设计
摘要：PLC又称可编程控制器，国际电工委员会于1985年对其做了如下定义:”可编程控制器是一种数字运算操作的电子系统，专为在工业环境下应用而设计。它采用可编程的储存器用来在其内部储存执行逻辑运算.顺序控制.定时.计算和算数运算等操作的指令，并通过数字.模拟的输入和输出，控制各种类型的机械或生产过程。“无锡位于长江三角区，是一个相对发达的地方。标签是指产品上的文字图形符号及一切的说明物。 随着市场经济的发展和商品的激烈竞争，标签已成为公平交易、商品竞争的一种重要形式。标签打印系统是用于工业、商业、超市、零售业、物流、仓储、图书馆等需要的条形码、二维码等标签制作，具有采用准确控制、高速运行、一体制作等要求的系统，用PLC控制环节少，比较直观。本文就是基于PLC标签打印控制系统的设计。标签打印控制系统主要由可编程控制器、驱动装置和传动装置组成。主要工作原理是PLC控制电气控制回路来完成标签打印工作的进行。

Design of print control system based on PLC tag
Abstract: PLC is also called programmable logic controller (PLC), the International Electrotechnical Commission in 1985 to do is defined as follows: "programmable controller is a digital computing operation of electronic systems, designed for applications in industrial environments designed. It adopts programming memorizer is used for in its internal storage implementation of the logical. Sequential control. Timing. The calculation and arithmetic operations such as instruction, and through digital. Analog input and output, control various types of machinery or production process.Wuxi is located in the Yangtze River Delta region, is a relatively developed place.Label refers to the products of text and graphical symbols and all that. With the fierce competition in the market economy and the development of commodity, the label has become fair trade, commodity competition an important form. Label printing system is used for industrial, commercial, supermarkets, retail, logistics, warehousing, library and other needs of the bar code, two-dimensional code label production, with accurate control, high-speed operation, various production requirements of the system, using PLC control with fewer links, more intuitive. This article is based on PLC label printing control system design. Label printing control system mainly consists of a programmable controller, the drive device and a driving device composition. Main principle is PLC control electric control circuit to complete the label printing work.
Key words: : label printing control system: PLC control
