Elevator Simulation Run System Controlled by PLC
Abstract：This graduation project is about the simulation of the five-story elevator by PLC programming and with WinCC. And it will be showed by animation. With the development of science and technology, our daily lives cannot lack of convenience brought by elevator. The elevator is not only important equipment in the production processes, and it is transportation equipment used frequently. Pursuant to this article on the basis of the interpretation of the elevator structure, the programmable controller structure and working principle, we achieve the five-story elevator control system with a Siemens s7-300 programmable controller. In this design, by two to complete this simulation, the model one is to achieve the operation of the elevator, and the other is to achieve a lift within the call response, response to external call, the priority control floors, the elevator stops running direction and layer station control, automatic operation and automatic closing and other basic functions.
Keywords: five-story elevator, simulation, PLC, WinCC configuration
