Design and Implementation of Wireless Intelligent Lock System Based on Cloud

针对无线智能锁功耗高、智能监控便利性差等问题,提出一种基于433MHz频段转WiFi技术进行远程智能监控的智能锁系统。为了解决系统点对多点通信中互相干扰的问题,433MHz频段无线组网采用时分多址(TDMA)技术。门锁端的相关信息通过433MHz频段传输到集中器,然后转发到云端服务器,以此连接远程客户端进行远程监控。实验结果表明:远程客户端能实现对智能门锁的实时智能监控,系统通信稳定、可靠,且有效降低了功耗,达到了系统设计目的。

Aiming at the wireless intelligent lock with the high power consumption and low convenience of intelligent monitoring,this paper proposed an intelligent lock system with feature of remote intelligent monitoring through local communication based on433MHz frequency band and WiFi technology for access to the cloud server.In order to solve the mutual interference problems during multipoint communication of this system,time division multiple access(TDMA)technology was adopted for the433MHz frequency band wireless network.The related information of the door lock terminal was transmitted to433MHz to connect WiFi module through433MHz band.Then this WiFi module sent the information to the cloud server to connect the remote client for remote control.Many experiments showed that the remote client can monitor intelligent door lock intelligently in real time.The communication of the system was reliable and stable.Low power consumption was controlled well.The system reached the design requirements.
