基于PLC在电梯控制系统中的设计(附plc语句,流程图,接线图和梯形

先对六层电梯的硬件部分作分析。本设计就以PLC作为工具对升降电梯的各种操作进行操控。若用PLC 操控就解决了以上的不足。它不仅存在着可靠性差、成本高、故障率高等缺点,而且在层数增加时,配线变化给制造及安装带来诸多不便。国内传统的电梯操控一是由继电器、接触器构成。然后,

DESIGN of THE CONTROL SYSTEM of ELEVAROR BASED on PLC
Abstract: The rapid development of the national economy, the increasing degree of modernization, more and more high-rise buildings, elevators also will be increased, Elevator products in people's material and cultural life of the status has been enhanced to become one of the important transport equipment. Traditional domestic elevator control from the first relay, a contactor. It is not only poor in the reliability, high cost, high failure rate shortcomings, but also in layers increases, changes to the wiring and installation of manufacturing has brought many unchanged. If the control by PLC to address the above shortcomings. the design of the PLC as a tool to the elevators for various operating control. Elevator on the first six parts of the hardware analysis, the need to see what kind of switches, motors, lights, etc.. Then, the control panel draw maps, plans, under the control panel is estimated to I / O points, so certain selected models, and then softwaredesign, write flowchart, ladder diagram, write statements.
Key words: PLC control system;Elevator;relay;ontactor

,写出流程图,再根据操控面板图估计一下I/O点数,信号灯等。这样可以确定所选机型,看需要什么样的开关,画出它的操控面板图,电机,然后在软件设计,梯形图,写出语句
