PLC和组态软件的三层电梯控制系统设计+梯形图

摘要：电梯是如今社会必不可少的运输工具，在运送乘客和货物起着极大的作用。而比起采用继电器-接触器控制的传统电梯，采用PLC和组态软件组成的控制系统可以很好的解决了触点多，故障高，维修量大等问题。使电梯更加安全，方便，舒适。本文介绍了基于PLC和组态软件设计的三层电梯控制系统。详解了电梯结构组成，以及PLC和组态王在电梯设计中程序设计。同时阐述了PLC的结构，语言，电梯设计中的应用。同时也阐述了组态王软件的基本原理和用法，以及它在电梯设计中监控和仿真的人机界面。该系统不仅实现了对电梯的控制和监控，而且实现了对电梯的模拟和调试。最后附上详细的STEP7的编程语言，和组态王实现的人机界面。该设计提供的电梯控制系统方案可以随时监控电梯的运行状态，同时解决了可靠性差，故障率高，等一系列问题。55441

Abstract: Today, the community is essential to lift vehicles, transporting passengers and cargo plays a great role. Rather than using the relay - a traditional elevator contactor control, the use of PLC control system and configuration software can be a good solution to many contacts, failure is high, the amount of maintenance and other issues. The elevator is more safe, convenient and comfortable. This paper introduces three text-based PLC elevator control system software design and configuration. Detailed structure and composition of the elevator and the elevator PLC and King in the design of programming. Also explained the structure, language, elevator design of the PLC application. Also describes the basic principles of software configuration king and usage, as well as its monitoring in the elevator design and simulation of human-machine interface. The system not only realizes the elevator control and monitoring, and the realization of the elevator simulation and debugging. Finally, attach detailed STEP7 programming languages, and King realize man-machine interface. Elevator control system solutions provided by the paper can always monitor the operational status of the elevator, while addressing the poor reliability, failure rate, and other issues.
