【摘要】 针对传统家居安防系统存在布线困难、建设及维护费用高昂、接收报警信息不及时等问题,提出一种基于物联网实现家居安防系统的设计方案。系统采用嵌入式ARM9处理器S3C2440A为系统主控制器,负责接收并处理工作在2.4GHz ISM频段nRF24L01射频芯片所传送的报警信息,并通过对象名解析服务器查阅报警信息服务器。使用socket套接字实现报警信息的网络传输,最终达到及时报警,远程终端实时监测家居安全情况的目的。实验测试表明,系统取得预期效果。更多还原

【Abstract】 Aiming at the defects of the traditional security and defense system,such as wiring difficulties,high construction and maintenance expense,delay of receiving alarm information,a scheme based on Internet of things was proposed.Embedded ARM9 S3C2440A microcontroller was employed as system master CPU,which performs as receiving and processing the transmission alarm information of RF chip working at 2.4GHz ISM band and searching the alarm information server by Object Name Service(ONS).Alarm information was transmitted on Internet in time by using socket,and the remote terminal will real-time monitor the home security situation.The experiment results indicate that the system achieves expected effects.更多还原
