新协议驱动住宅照明无线控制

　　新协议驱动住宅照明无线控制

　　新协议和开放标准正在出现，这些技术有助于推动家庭自动化中无线链路的数量并降低成本。在住宅环境中控制照明系统提供了更多的能源成本可控性，将照明连接到可以通过智能手机、平板电脑和PCs.等设备访问的中央网关。

　　但是围绕不同的无线技术仍然存在成本和干扰的问题。虽然WiFi是一种开放的标准，在家庭中很流行，它可以承载多媒体数据，但在住宅控制应用中，比如照明，它的数量并没有大幅度增长。

　　其他2.4 GHz的技术，如ZigBee，已被用于家庭自动化设备和网状网络的方法越来越流行的连接在家里的元素，特别是照明系统的控制。其他技术，如Sigma Designs的Z-Wave无线协议和EnOcean也出现在较低的非授权频段在315兆赫和868兆赫。

　　德国的无线专家EnOcean现在看到它的无线短数据包协议作为国际标准化组织（ISO）标准。

　　The ISO/IEC 14543-3-10 standard for Home Electronic Systems （HES） uses the EnOcean protocol and the first three layers to provide a consistent basis for the development of ultra-low power wireless controllers. This move to an open standard will allow silicon vendors and module makers to develop gateways that will connect to sensors and controllers that use the EnOcean technology. By creating an open standard for such designs， EnOcean sees an increase in volume and a reduction in cost to further drive the technology into the home.

　　The EnOcean technology has been developed over the last ten years and uses regulated frequency ranges approved for pulsed signals at 868.3 MHz or 315 MHz for worldwide use coupled with a prearranged transmitter-to-receiver assignment with four billion fixed code numbers to provide this reliability， which is now within an open standard environment. The radio uses ASK and low data rates of 125 Kbit/s to keep the costs down， along with short telegrams that are sent at random to avoid collisions.
