| Along with the our country economy rapid development, the urban population increases day by day, specially since along with the Reform and open policy, the automobile total quantity is more and more. Formerly that kind of Single-Layer plane parking lot could not satisfy the demand of the market. To the multi- parking spots, little occupies of the space, the use operation is simple. "Three-Dimensional Garage", which is the effective solution of stops difficult in the present big city.The Three-Dimensional Garage, which takes the single-layer plane parking lot as the core, is the multi-dimensional space parking garage. It uses the programmable controller (Programming Logic Controller, also called PLC) to realize multiple monolayer plane stops by controlling the berth space position the change. Vertical-horizontal moving underground car parks, which realize multilayer berth fluctuation deposits and withdraws the vehicles by shifting the tray to produce the vertical channel.The article researches the theory of the Three-Dimensional Garage, it has discussed the method and the step of using Programmable-Controller PLC to realize the garage control system, and unified KEYENCE KZ - 80T to introduce the realization 3x3 three-dimensional garage model design and the realization situation. The system simulation uses controls configuration software MCGS, which is based on the WINDOWS platform. Through establishing the database of configuration software constructs, connecting the animation, preparing the control flow and debugging the procedures, it has realized the three-dimensional garage monitoring system.The article research has the certain practice significance in the area of applying the PLC in the computer control system as well as using MCGS to achieve real-time monitoring of industrial projects, which raises the level of industrial automation. |
