基于PLC的立体停车库系统设计 摘要 ：The Design of a Stereo Garage System Based on PLC Abstract This paper analyzed the structure of a variety of parking garages. It includes the parking systems theory, an overview of the type and characteristics. By comparing the characteristics of a variety of solid garage, we draw a conclusion that parking garage can lift and transfer is the best choice for Ordinary household plot. In addition, it described how the new Stereo Garage System works in detail. Then, it illustrates the movement characteristics and functional requirements of this new solid garage. Again, the general scheme of the control system has determined. It introduced the components of the Stereo Garage and described the hardware and software components in detail. It explored the methods and procedures to achieve this new parking garage that controlled by the programmable logic controller PLC. Throughout this article, including selection, work steps, working principle and work characteristics of the PLC. According to the working process of solid garage, I draw a whole flowchart of the parking garage based on PLC and wrote the block diagram. This new solid garage has an important reference for the research of parking garage in the future.
