基于NRF2401无线收发的停车场诱导系统设计
基于NRF2401无线收发的停车场诱导系统设计(论文14000字)
摘要：随着我国经济的快速发展，车辆变得越来越多。传统停车位系统只能够显示出停车场停车位的总数量以及停车场出入口的控制，收费仍需人工来操作。对于停车场内部的停车引导、快速进出等功能还不能够实现，所以本文设计了一种基于NRF2401无线收发模块，红外对管传感器及单片机技术的停车场诱导系统。该系统利用红外对管传感器技术，在每个车位都安装了一个红外对管传感器，构造了停车场的车位检测系统。当人们把车停在了装有红外对管传感器的停车位上，传感器会发送一个数字信号到51单片机上，利用NRF2401无线收发模块实现无线传输，显示模块接收到数据后由LCD1602液晶屏显示出车位停车的状态信息。为了完善一个停车场诱导系统的完整性，在实现基本功能的基础上，添加了一个RC522射频模块和LCD12864液晶屏来提高停车场的安全性能以及实现实时扣费功能。当M1卡靠近RC522模块时，LCD12864显示屏中显示出卡号，扣费金额，剩余金额等。该系统不仅能够有助于缓解人们停车浪费时间的问题，而且有效地减轻了工作人员的工作量，也大大提高了停车场的安全性能，使人们停车变得更加便捷，车主可以享受到汽车在生活上给他们带来的便捷。本文实现了以下几个功能：（1）实时扣费，减轻了工作人员的工作量。（2）停车场的诱导，能够及时地提醒车主具体几号车位有空位。

Parking lot induction system based on NRF2401 wireless transceiver
Abstract:.With the rapid development of China's economy, vehicles are becoming more and more.
The traditional parking space system can only display the total number of parking spaces in the parking lot and the control of the entrance and exit of the parking lot. The charges still need to be manually operated.For the parking guidance, fast access and other functions inside the parking lot can not be achieved, so this paper designed a parking lot induction system based on NRF2401 wireless transceiver module, infrared tube sensor and single chip technology.The system utilizes infrared pair tube sensor technology, and an infrared pair tube sensor is installed in each parking space to construct a parking space detection system for the parking lot.When people park the car on the parking space equipped with the infrared sensor, the sensor will send a digital signal to the 51 MCU, and use the NRF2401 wireless transceiver module to achieve wireless transmission. After the display module receives the data, it will be displayed by the LCD1602 LCD. Status information of parking spaces.In order to improve the integrity of a parking lot induction system, on the basis of the basic functions, an RC522 RF module and LCD12864 LCD screen were added to improve the safety performance of the parking lot and realize the real-time deduction function.When the M1 card is close to the RC522 module, the LCD 12864 display shows the card number, the deduction amount, and the remaining amount.The system not only helps to alleviate the problem of people wasting time wasted, but also effectively reduced the workload of the staff, and greatly improved the safety performance of the parking lot, making people parking more convenient, and the owner can enjoy the car. The convenience brought to them in life.This article implements the following functions: (1) Real-time deduction, which reduces the workload of the staff. (2) The induction of the parking lot can promptly remind the owner that there are vacancies in the specific number of parking spaces.
