摘　　要：为进一步提高家居生活的智能化和便捷化,文中设计了一款嵌入式智能家居控制终端。该终端以NXP(恩智浦)公司的ARM7TDMI处理器LPC2214为核心,集多款家电操控和状态监控界面于一体,通过扩展RF模块组建家庭内部无线网络。该终端既可以伴随相应的语音提示,通过按键进行家电操控界面切换和相应功能的选择及遥控,又可通过WiFi模块接收由平板电脑或智能手机上家电控制软件下发的控制命令编码,最终实现对家电的遥控。同时,家电状态的变化也会实时反馈给控制终端、平板电脑或智能手机进行状态显示更新。该方案解决了对家电远程遥控和状态的实时监控问题。经过实验测试,该终端具备轻巧便携、控制精准、速度快等特点,非常适宜在智能家居系统中应用。In order to further improve the intellectualized and convenient of the household life,an embedded intelligent household control terminal was designed. The terminal was based on ARM7TDMI embedded processor LPC2214 of NXP company,integrated different con-trol and state display interfaces of home appliances in a body,the RF module were expanded to achieve the construction of wireless net-work. This terminal can not only switch the control interfaces of home appliances and choose or control one of the functions in the corre-sponding control interface through the keyboard along with the corresponding voice prompt,but also receive control commands from the control software of home appliances that installed in the PAD or intelligent mobile phone through the Wi-Fi module,ultimately achieving the purpose of the control of home appliances. At the same time,if one of the states of a particular home appliance has been changed,it can timely feedback to the control terminal,PAD or intelligent mobile phone so that to update the current state of the display. This plan solved the problem of real-time monitoring of the state and the functions of remote control for the home appliances. The experimental re-sults show that,the control terminal has the characteristics of light and handy,high control precision and high speed,is very appropriate for application in intelligent household system.
