摘要
为了解决目前门禁系统存在的高功耗、高成本和低扩展性等问题,设计一种基于51单片机和nRF24L01无线收发芯片的低功耗无线门禁控制系统.系统由发射端和接收端组成,发送端接收、加密并发送上位机控制信号.接收端接收和解密信号并控制门禁系统.经过多次不同环境下的分组测试证明,该系统成本低,实时性好,安全性高,扩展性好,适用于不同环境下的多种小型场所.
This paper presents the hardware and software design of a low-power wireless door-guard control system based on 51 MCU and nRF24L01 wireless transceiver chip,so as to solve the current door-guard system for high power,high cost and low expansibility problems.The system consists of a sender and a receiving end.PC control signals are received,encrypted and sent by the sender.The receiving end receives and decrypts the control signals and controls the door-guard system.The result of many different environment grouping tests shows that the system is of low cost,good real-time performance,high security,good scalability and is suitable for a variety of small spaces with different environments.
