Abstract
The rapid increase of private cars has reduced the average coverage for each citizen and made them park more difficult. But the increasing private cars has further accelerated the development of a three-dimensional garage which has a three-dimensional space, and the development to the high-level automated parking equipment. The three-dimensional garage has the advantages of less area, more efficient of parking, flexible layout, energy-efficient performance, high cost-effective, safe and reliable and so on.
Nowadays there are 8 types of three-dimensional garage. They are PSH, PCX, PDX, the level of cycle-type, flat mobile category, type of roadway stacking, vertical take-off and landing type and simple movements. And PSH has the advantages of simple structure, easy to operate, safe, reliable, low cost, and dominates domestic market. The main task of this article is to design the system of PSH and briefly introduce the structure of the garage and transmission mechanism. There are three main forms of the garage control system. After being compared and analyzed, PLC is considered to be the garage-core of control. It has finished the selection of PLC according to the input and output of parameters in work.
Key words Three-dimensional garage ；Programmable Logic Controller；Control System .
