基于 PLC 的五层电梯控制系统设计 I 基于 PLC 的五层电梯控制系统设计电气工程及其自动化专业*** 【摘要】电梯不仅仅是高层建筑里的必备设施,在多层建筑里也是不可缺少的垂直运输工具。据此本文在阐述电梯的结构和可编程控制器的结构和工作原理的基础上,针对 5层5 站电梯,使用西门子 200 可编程控制器,设计了电梯的控制系统。实现了电梯的指层控制、轿内与各层厅站呼梯指令的记录、电梯运行方向和停靠的层站的控制,自动运行和自动开关门等功能。这种电梯控制系统应用于实际运行的电梯中,运行结果表明:电梯控制系统安全性和可靠性高,日常保养维护和故障检修方便,运行成本低。【关键词】电梯;控制系统;可编程控制器; S7-200 Design of Five Floors ’ Elevator Control System Based on PLC Electrical Engineering and Automation Specialty *** Abstract : The elevator isnot only the necessary facility in the high-rise building, but al so the essential vertical transport means in the multi — layered construction. This article elaborated the elevator structure , the structure and the working principle of the programmable logic controller . Aim at the elevator of5 floors and 5 stations ,I design this elevator control system by the use of S7-200 programmable logic controller. These modules achieve the functions : fingering out the location of the cabin , registering the instructions from the cabin and the station hall . choosing the direction and the station of elevator follow these instructions , operating elevator and door automatically , and other functions. This elevator control system applies in the actual operating elevator .The operating result indicated : its security and reliability ale high, the routine maintenance and the trouble shooting are convenient, the elevator operating cost is low.
