摘  要

PLC可编程序控制器是以微处理器为基础，综合了计算机技术、自动控制技术和通讯技术发展而来的一种新型工业控制装置。它具有结构简单、编程方便、可靠性高等优点，已广泛用于工业过程和位置的自动控制中。据统计，可编程控制器是工业自动化装置中应用最多的一种设备。可编程控制器将成为今后工业控制的主要手段和重要的基础设备之一，PLC、机器人、CAD/CAM将成为工业生产的三大支柱。由于PLC具有对使用环境适应性强的特性，同时其内部定时器资源十分丰富，所以很多公司都在使用PLC来控制生产线的运作，比如生产显示器、电视机就利用到了升降机。利用升降机可以把显示器运送到加温层，运送包装线，在运送的过程中就可以利用PLC控制，进行测试、检验。最后实现科学运作。

本文主要是升降机控制系统的PLC应用研究。主控系统采用FX2N48MR-001PLC为控制核心,结合模拟量输出模块FX2N-2DA,并设计了施工升降的理想速度曲线。PLC系统完成了所有I/0信号和上位机串口通信信号的接收,根据其内部设计程序进行集中运算处理,实现了对液压施工升降机的控制系统的逻辑信号及速度控制。另外,还根据控制系统要求,设计了控制系统主回路、安全运行电路、电液比例控制回路等。

Abstract

PLC programmable logic controller is a microprocessor based on a combination of computer technology, automatic control technology and communication technology evolved a new type of industrial control devices. It has a simple structure, easy programming and high reliability.It has been widely used in the automatic control of industrial processes and position. According to statistics, the programmable controller is the most widely used kind of equipment in the industrial automation devices. Programmable controller will become one of the main means of industrial control and important infrastructure, PLC, robotics, CAD / CAM will become the three pillars of the industrial production. PLC has the use of environmental adaptability characteristics, while its internal timer resources are very rich, so many companies are using the PLC to control the operation of the production line, such as the production of the display, the TV on the use of the lift. Lift the monitor can be transported to the heating layer, transport packaging line, in the course of transportation can make use of PLC control, test, test. Finally, science operations.

In this paper, the lift control system PLC applied research. The master control system for the control of the core FX2N48MR-001PLC, combined with analog output module FX2N-2DA designed the construction lift the ideal speed curve. A PLC system to complete all of the I / 0 signal and the host computer serial communication signal receiver, according to its internal design process, the central arithmetic processing logic signals and speed control of the control system of the hydraulic lift construction. In addition, according to the requirements of the control system, the design of the control system the main loop, the safe operation of the circuit, electro-hydraulic proportional control loop.
