基于nRF24L01模块的小区无线报警系统的设计与实现

Application and Design of Wireless Community Alarm System Based on nRF24L01 Module

住宅小区无线报警系统基于单片机控制,使用nRF24L01无线通信模块,实现组建住宅小区的无线报警系统。本设计通过无线通信模块实现多对一双向传输,组建由中央总控台主机和用户子机构成的无线报警网络,具有数据双向传输、频率稳定、接收发射合一的特点。用户通过子机发送报警信号,主机接收信号显示用户地址并发出报警。经过实验多次测试,系统均能准确无误的实现及时报警。

The wireless alarm system is controlled by Microcontroller,and uses nRF24 L01 wireless communication module to build the wireless alarm system of residential area.This design through the wireless communication module of a two-way transmission to realize the wireless alarm network by the central monitoring room and users,and the characteristics of this design is frequency stability,reception and emission integration.The user sends the alarm signal through the user sub-machine alarm.Then the host receives the signal and displays the user’s address and sends out a warning.After many experiments,this system achieves all the alarming in time.
