结合移动互联网技术、物联网技术、无线射频技术以及单片机嵌入式技术,利用SIM300 GSM模块、nRF24l01射频芯片与STC12C5A60S2单片机以及路由器组建基于微型Linux系统的核心控制器,同时利用nRF24l01射频芯片、单片机和继电器模块组成控制终端,通过nRF24l01芯片以2.4G频率将各从机与控制器进行无线组网。用户可通过网络可视化软件下发指令或者手机发送短信指令到核心控制器,核心控制器提取分析短信或控制指令并通过单片机发送指令到指定的终端,终端收到指令后将根据指令控制继电器的耦合和分离,实现电器的开启与关闭,并将控制后的状态反馈给核心控制器,控制器将实时状态通过网络或者短信告知用户控制成功与否,从而实现对智能家居的远程控制。测试结果表明设计的智能家居系统能完成相应的功能,通过各个模块的协调控制,能提高系统的可靠性和通用性。
Combined with mobile Internet technology, Internet of Things technology, radio frequency technology and embedded microcontroller technology, the core controller based on micro-Linux system is built by using SIM300 GSM module, nRF24l01 RF chip and STC12C5A60S2 microcontroller and router, and the nRF24l01 RF chip, microcontroller and relay Module control terminal, through the nRF24l01 chip 2.4G frequency of the slave and the controller for wireless networking. The user can send instructions to the core controller through the network visualization software or the mobile phone. The core controller extracts and analyzes the short message or the control instruction and sends the instruction to the designated terminal through the single-chip microcomputer. Upon receiving the instruction, the terminal controls the coupling of the relay according to the instruction And separation, to achieve the opening and closing of electrical appliances, and the control of the state feedback to the core controller, the controller will be real-time status through the network or text message to inform the user control the success or failure, in order to achieve remote control of the smart home. The test results show that the design of the smart home system can complete the corresponding function, through the coordinated control of each module, can improve system reliability and versatility.
