基于 PLC 的装配流水线的控制系统设计摘 要随着微电子技术和计算机技术的不断进展, PLC 在处理速度、 控制功能、 通信能力及控制领域成为工业自动化领域中最重要、 应用最广泛的控制设备之一, 并已成为现代工业生产自动化的重要支柱。对装配流水线的控制进行了分析设计, 该系统主要引入了 PLC编程控制器的控制方式, 实现了对装配流水线的工作状态的在线监测和系统自动控制。设计的控制系统具有较高的有用性, 能够进行启动、 移位、 复位工作, 较好地达到预期目标。本次设计是装配流水线控制的模拟, 主要是模拟流水线上产品所经加工过程的控制和生动的表示。模拟主要流水线有四个操作过程( 包括入库) , 传输带用四段指示灯表示, 以指示灯的明暗来显示产品在运输这一状态。分析控制对象我们选择用移位寄存器控制来实现控制目的, 每隔 5 秒寄存器移位一次, 从而控制相应操作的执行。关键词: 装配流水线, PLC,控制系统DESIGN OF CONTROL SYSTEM OF ASSEMBLY LINE BASED ON PLCABSTRACTWith the development of the microelectronics technology and computer technology, PLC in processing speed, control function, communication ability and control fields have new breakthrough. Become one of the most important control equipment in the field of industrial automation, the most widely used, and has become an important pillar of the modern industrial production automation.Control of the assembly line are analyzed and designed, the system is mainly introduced PLC control programming controller, realized the on-line monitoring system of assembly line and the working state of automatic control. Practical design of the control system has high, can start, shift work, reset, can reach the expected goal. The design is simulated assembly line controle, simulation is the main line of products through the control of process and the vivid representation. Simulation of main line is four operations (including storage), transmission belt with four indicates, to display the products in the...
