PLC在四层电梯中的应用设计(16000字)
摘要
随着我国国民经济的飞速发展。他不仅存在着可靠性差、成本高、高故障率等缺点,对电梯技术和电梯装置的发展进行了综述。国内以前传统的电梯操控是有继电器、接触器构成。然后,画出程序流程图,画出他的操控面板图,电梯产品在人们的物质文化生活中的地位也得到了提高,电梯也随之增多,现代化程度日益提高,根据电梯系统自身的工作状态要求,根据I/O点数来确定PLC机型,最后再进行原件设计,成为重要的交通运输装置之一。先对四层电梯的硬件部分做分析,而且楼房层数增加时,结合PLC自身的操控规律,突出讲述继电器电梯操控系统暴露的缺点以及PLC电梯操控系统所具有的优点,看需要什么样的开关、信号等等。
本设计就以PLC做为工具对电梯的各种操作进行操控。
首先,通过软件开发的特点,进行电梯系统的PLC软件开发,设计出可实现一定功能的PLC电梯操控系统。若用PLC操控就解决了以上的不足。
关键词：PLC 电梯 操控系统
Abstract
With the rapid development of China's national economy, increasing the degree of modernization, many high-rise buildings, elevators also will be increased, elevator products in people's material and cultural life of the position has been enhanced to become one of the important transportation equipment. Domestic ones the elevator control is a relay, contactor composition. He was not only the existence of poor reliability, high cost, high failure rate and other shortcomings, and building layers increases, changes to the manufacturing and installation of wiring inconvenience. If using PLC control to solve the above deficiencies.
First, respectively expounds elevator relay control and PLC control features, outstanding tells relays of elevator control system exposed shortcomings and PLC of elevator control system has the advantages, secondly, in the domestic and foreign relevant document read many of the basis of materials, the elevator technology and the development of elevator equipment are reviewed. Then introduces PLC selection principles and PLC control system design train of thought; On this basis, according to the elevator system itself working condition requirements, elevator systems PLC software development, through the software development of characteristic, combining PLC itself, the design gives the control law can realize a certain function PLC elevator control system.
The design of the PLC as a tool for the elevator on the ginger to control the various operations. The first part of the hardware to do three of the elevator and see what kind of switches, signals and so on. Then, the control panel to draw his map, according to I / O points to determine the PLC model, and finally the original design, draw flowchart, write the ladder, followed by computer simulation.
