AT89S52单片机的停车场智能控制系统设计
Title The design of an intelligent control system of parking lot based on MCU
Abstract
In this thesis, we mainly study an intelligent control system of parking lot based on MCU. Traditional parking control systems pay more attention to the billing, charge and the time of incoming and outgoing of every parking space. In this thesis, the ID card of the design is used as the media of charge and we re-design the management system. The new system comprehensive display the parking situation of parking lot. The system is pided into two systems:toll system and control system. The toll system mainly uses AT89S52, AT24C512 and FM1702SL, and the control system mainly uses ST89C51, Infrared Emitting Diode, CD4069 and ST7920. This system can not only charge but also very intuitive displaying the number of free parking place in the parking lot as well as the specific free parking. It is convenient to the users and solves our country's problem of difficult parking.
