The Mechanical Structure And Control System Design Of Mechanical Tridimensional Garage

With the development of economy and urban construction in China, the mechanical tridimensional garage integrated a variety of technologies has become an inevitable way to solution the city parking. In this paper, it studies the mechanical structure, the control system and vehicle scheduling optimization of the tridimensional garage.First of all, expatiated the overall structure of garage, and introduced the structure and operation principle about the steel frame, lifting mechanism, sliding mechanism and turntable in detail. After analysis of the structure and operation characteristics of the handling device, it is designed two hydraulic handling devices, and focused on the structural characteristics and operating principle respectively. It is significant to study the garage technology.Secondly, based on the distributed control system theory, and analysis the movement characteristics and function demand of the garage, the overall project of control system is determined. Based on the idea of centralized control and decentralized management as a guiding principle, constitute the form of IPC and PLC in order to achieve the control goal.PC hardware chooses the IPC as a host computer, and complete man-machine interface and communication procedures. Based on point-to-multipoint communication network, communications system selects the RS232/RS485 communications hardware, set up a communication protocol to ensure smooth communication between up and down position.The distributed device complete the movement position of mechanisms, it is designed the overall layout of PLC, distribution I / O point , and circuit diagram, and selected the hardware the others components, and finally realized the connection hardware, software procedures. The overall control system was debugged to the control function.Based on the disadvantage of the average long waiting time for the user, stacker of a larger workload caused by the tridimensional tunnel-type stacking garage less entrances and exits of the vehicle.,From the perspective of scheduling strategy analysis, it optimizes the parking by the improved genetic algorithms, and improves the access sequence of garage by using the hybrid coding and the improved cross-OX operator, so that the total vehicle access time at least, the average waiting time to a minimum for users. After simulation experiments, a better result obtained. It is significant to improve access strategy of garage.
