"基于PLC的四层电梯控制系统设计与仿真"

系统, including the registration and elimination of car instructions and hall outside call signals, elevator selection and orientation, elevator door opening and closing operation, elevator up and down control, and elevator floor selection control, etc. It realizes the recording of car instructions from each floor, the control of elevator direction and floor selection, elevator up and down operation and automatic door opening and closing, and elevator floor selection control. At the same time, the simulation of the PLC-controlled elevator was also achieved using configuration king 6.53. Keywords: Four-story elevator, control system, programmable controller, configuration king. In summary, the thesis "PLC-based Elevator Control System Design" focuses on the design and implementation of a control system for a four-story elevator using a programmable logic controller (PLC) and configuration king. The paper provides an overview of elevator control systems and explains the advantages of PLC control systems over relay-based and microcomputer-based systems. It then details the design and implementation of the elevator control system, including the registration and elimination of car instructions and hall outside call signals, elevator selection and orientation, elevator door opening and closing operation, elevator up and down control, and elevator floor selection control. The use of Siemens S7-200 PLC is highlighted, and the paper also discusses the simulation of the PLC-controlled elevator using configuration king 6.53. Overall, the paper offers a comprehensive study of the design and implementation of a PLC-based control system for a four-story elevator, highlighting the advantages and functionalities of such a system.
