由于经济的发展，城市人口、城市车辆逐年増多，市区停车问題亟待解決。传统的单层平面停车场占用大量宝贵的土地资源，越来越不能满足需求现代先进的自动化机械立体库是一种多平面的空间立体库，它以单层平面停车库为核心，通过微机(即通过上位机对车库进行统一的管理、监护与PLC控制来进行车位的空间位置变动，使车位实现由空间到平面的转化，从而实现多层平面停车的功能。

Due to the development of economy, the urban population, urban vehicles increased year by year, the urban parking problems to be solved. Traditional single plane parking lot take up a lot of valuable land resources, more and more can't meet the demand of modern mechanical three-dimensional library is a kind of more advanced automated flat space stereo library, it with single plane parking garage as the core, through the microcomputer (i.e. through the PC to the garage for unified management, monitoring and PLC control for parking space position changes, ensures to realize by space to the transformation of the plane, so as to realize the function of multilayer planar parking.
