原标题：智能家庭无线中控

　　随着社会的不断发展，信息交流和沟通也就变得越来越频繁，越来越重要。各种视听设备、投影设备，灯光，智能家电等开始进入现代化家庭。多种设备的使用必定带来烦杂的设备操作。要打开多种设备电源，如：要关闭灯光，要频频切换各种智能家电信号，要不断切换开关等等。在这种情况下，一种能够集中管理这些设备，并能同时控制智能家庭各种资源的“无线 [中央控制系统]”设备便应运而生。

　　用户可用按钮式 [控制面板]、计算机显示器、触摸屏和无线遥控等设备，通过计算机和[中央控制系统] 软件控制视听设备、投影设备，智能家电、电动窗帘、灯光等设备。当把几个独立的 [中央控制系统] 相互连接起来，就可构成网络化的中央控制系统，可实现资源共享、影音互传和相互监控。作为一个智能家庭无线中控一般由四部分组成：1. 用户界面; 2. 中央控制主机;3. 各类无线控制接口;4. 受控设备。

　　当今的智能家居快速扩展到许多设备和终端节点。这需要同时了解多个无线协议的用户界面。这些显示器是无线的，不需要壁挂式供电，可以进行无线充电和供电，从而更轻松地监控智能家居。NXP 解决方案可以帮助创建引人入胜、具备用户界面显示器，可以与所有的物联网智能家居设备通信。

　　Image of NXP Semiconductor JN5169XK010,598: ZigBee Generic Node Expansion KitThe JN5169 from NXP Semiconductor is an ultra-low-power, high-performance wireless microcontroller suitable for ZigBee applications. It features 512 kB embedded Flash, 32 kB RAM, and 4 kB EEPROM memory, allowing OTA upgrade capability without external memory. The 32-bit RISC processor offers high coding efficiency through variable width instructions, a multi-stage instruction pipeline, and low-power operation with programmable clock speeds. It also includes a 2.4 GHz, IEEE802.15.4 compliant transceiver and a comprehensive mix of analog and digital peripherals. The best-in-class RX operating current (down to 13 mA and with a 0.7 μA sleep timer mode) gives excellent battery life, allowing operation direct from a coin cell.

　　The peripherals support a wide range of applications. They include a two-wire, compatible I²C-bus and SPI-bus which can operate as either master or slave and a six-channel ADC with a battery monitor and a temperature sensor. It can support a large switch matrix of up to 100 elements, or alternatively, a 40-key capacitive touch pad.
