摘要
本文主要以智能家居系统中的LED节能灯智能控制为例,设计一种基于2.4GHz WiFi通信技术和工作频率为433MHz的RF通信技术的无线网络通信方式。iPad客户端应用程序发出命令,通过WiFi信号传输到中央控制器处理,然后通过CC1101模块向各个节点发送指令,节点执行相应操作并向客户端应用程序作出应答,以此来达到控制节能灯的目的。本文对设计与实现的关键技术,如CC1101模块的收发数据、LED灯的驱动、客户端应用程序开发、UDP通信协议等进行了详述,也指出了智能家居控制系统的不足。
This article mainly takes LED energy-saving lamps intelligent control of smart home system as an example, it designs a wireless network communication based on 2.4 GHz WiFi and 433MHz RF communication technology. The iPad client application issues orders to the central controller by WiFi signal transmission, and the central controller sents instructions to the various nodes through CCll01 module, and then nodes perform the corresponding operation and are responsive to the client application in order to achieve the purpose of control of energy-saving lamps. The article details the key technologies of the design and implementation such as CC1101 module to send and receive data, LED lamp driver, the client application development, UDP communication protocol, etc, also points out the shortages of smart home control system. The artical has a certain reference value on the current development of smart home system.
