基于89S52单片机的停车场自动管理系统 NRF24L01
基于射频技术的停车场自动管理系统的设计与实现
摘要:随着社会的不断快速发展,人们的生活水平日益提高,车辆的数量也呈快速增长的趋势,如何安全、高效的停车已经成了人们关注的又一大问题。本课题就是基于城市小区或者单位的内部停车场如何实现安全、高效停车问题的设计。
本设计以单片机为核心,单片机控制无线通信模块,接收车辆信息,并根据
停车场当前停车情况安排车位,并将车辆及车位信息上传到PC机上并显示。利用单片机控制nRF24L01单片射频通信模块的收发功能,以及单片机与PC之间的串行通信。在软件方面包含单片机收发程序的编程,以及基于VB用于显示停车场当前信息的管理系统的编程。
本设计采用当前世界先进的射频通信技术,具有低成本、高效率和高稳定性
等优点,这使得本系统具备更高的可靠性与实用性。

The Design and Implementation of the Automatic
Car-park Management System Based on RF Technology
Abstract: With the continuous rapid development of people's living standards rising, the number of vehicles also showed a trend of rapid growth, the safe and efficient parking has become another big problem of people's attention. This topic is based on the internal car park of the city district or unit of the design of safe and efficient parking problems.
The design of MCU core, MCU to control the wireless receiver, the receiver
vehicle information, and the current situation based on parking arrangements for parking, and vehicles and parking information transmitted to a PC and displayed on the monitor .The hardware uses the serial port transceiver function of MCU and nRF24L01 Single-chip RF transceiver device transceiver functions, as well as the serial communication between MCU and PC. On the software side, contains a single-chip transceiver programming, and programming of the VC-based management system used to display the parking information.
This design uses RF communication technology, is currently in the world's
advanced technology has the advantages of low cost, high efficiency and high stability, which makes the system with higher reliability and practicality
Key Words: Automatic management system; RF transceiver; MCU
