2025 届 本 科生毕业论文 存档编号 湖北文理学院物理与电子工程学院毕 业 论 文（设计）论文题目：基于 PLC 和 MCGS 的四层电梯控制系统 English Topic: The Four Layer Elevator Control System Based On MCGS and PLC 基于 PLC 和 MCGS 的四层电梯控制系统摘要：本毕业设计上位机利用组态软件 MCGS 设计监控系统，下位机采纳 PLC来控制,并用，设计出一个自动化、稳定可靠、易操作的控制系统。控制系统采纳模块化设计，包括控制系统硬件设计、控制系统软件设计、组态软件的组态画面设计。其中系统硬件设计主要包括 PLC 的选型、I/O 地址分配、PLC 硬件I/O 接线；系统的软件设计主要是利用 GX-Works2 来完成梯形图的编程与调试；组态界面的设计主要包括用户窗口的建立；实时数据库的建立；以及运行脚本程序的编写等。电梯的主要功能模块包括响应轿厢内外呼叫按钮并到达相应的楼层、轿厢当前楼层显示模块、电梯门自动开关模块、内外呼叫按钮和开关门信号的输入与消除模块等。最后通过制作上、下位机的通讯协议以达到上位机实时监控的目的。关键词：PLC；MCGS；四层电梯；控制系统The Four Layer Elevator Control System Based On MCGS and PLCAbstract：Due to the traditional relay, contactor type elevator control system more and more clearly showed the unsolved problem of a short life, the line repair complex,. because of its easier use, high reliability and simple maintenance, PLC get the mass Pro resistance. This graduation design based on MCGS configuration software and PLC to control, and use the MCGS to PC for real-time monitoring, designed a automation, stable and reliable, easy operation of the control system. Modular design is adopted in the control system, including control system hardware design, software design of the control system, the screen configuration software design. The hardware design mainly includes the selection assignment of I/O address, PLC hardware I/O wiring PLC. Elevator main function in response to both inside and outside the car call button and ...
