Abstract
This paper elaborated on the composition of the smart parking, working principle, working conditions and management systems. The use of programmable logic controller (PLC) and out of car parking and parking management instructions. This program greatly enhance the work efficiency, maintenance cycle shorter and debugging convenience, lower cost. With a large number of imported cars Chung and the continuous development of the domestic automotive industry, large and medium-sized cities increased the number of cars, creating a parking management problem. In recent years, China's continuously improved parking management technology, computer technology, communications technology, network technology has facilitated the development of parking management system features powerful. However, now some want to use such as small parking lot of high-tech will be insufficient funding, inadequate maintenance and management questions, and sometimes not enough to consider a comprehensive, therefore, address the current high cost of vehicle management, low efficiency problem.
