摘要
智能家居系统主要是指利用计算机技术、网络技术、自动控制技术将家居生活中各种与信息相关的通信设备、家用电器等集成,实现集中或异地的监视、控制。文中从提高家庭内部设备之间的互联能力以及家庭网络与外部网络之间互联能力的角度,对智能家居的系统现状进行了总结,对理想的系统结构进行了描述;在此基础上,从频率、传输距离、传输速度等方面,对短距离无线通信技术进行了分析和比较,指出了Zigbee技术发送控制信息、UWB技术传送多媒体信息的优越性。最后对无线通信技术实施过程中的问题提出了一些建议。
In the system of smart home,all kinds of household-related communications equipments and household appliances were centrally or remotely monitored and controlled based on computer technology,network technology and automatic control technology.As viewed from improving interconnection capbility of equipments within the family and internet capability between home network and external network,system status and reasonable architecture of smart home were described.Short-distance wireless communication technology were analyzed and compared according to frequency,transmission distance and transmission speed.Some conclusion were proposed that transmitting controlled information based on Zigbee and transmitting multimedia information based on UWB had the advantage of other wireless communication technology.At last some suggestions about wireless communication technology＇s implementation in smart home were proposed.
