智能LED街灯与楼宇照明通信、控制及保护方案

智能照明(SmartLighting)涉及通信和传感功能,能够进行远程控制(开启或关闭、调光或改变颜色)和监控(远程诊断)建筑物、街道或家里的一个或多个灯具。智能照明也为灯具提供信息,使它能根据使用情况或环境光线等进行亮度调节。另一方面,高亮度白光LED非常适合区域照明应用,具有方向性更好、色彩质量更佳、环保等特点,并且能够更方便地控制其开启和关闭,便于自动检测环境光来改变亮度,使其在智能LED街灯等应用中越来越受瞩目。
  智能照明的通信可用无线或现有的电力线基础设施实现。电力线是世界上最大的铜基础设施,家庭或办公楼的每个角落都有电源插座,使之成为一个覆盖范围极为广泛的网络。
  鉴于所有照明灯具都是连接到电力线将电力转换成光,电力线通信(PLC)已成为智能照明主要通信和控制链路的合理途径。
  我司半导体利用其先进半导体技术,推出了针对智能照明的包括通信、传感器、KNX收发器及保护解决方案,有助于以更少电能执行相同(甚至更多)的任务,进一步提升能效,节约能源。
  例如,利用我司半导体的PLC调制解调器(如AMIS-49587)、PLC线路驱动器(如NCS5650)和诸如NOA1302这样的环境光传感器,可基于电力线轻松构建联网型LED街灯智能控制系统,有助于市政、电力公司和商业企业远程调节路灯的光输出,减少其路灯网络的整体能耗。此外,在楼宇智能温度调节及灯光控制应用中,也可在双绞线布线上使用KNX收发器,利用KNX网络进行照明控制。

电力线通信有助于公用事业公司为其配电网络增加更高级别的功能,从而让消费者更能掌自己的能耗。我司半导体提供一系列领先扩频型频移键控(S-FSK)PLC调制解调器,如AMIS30585、AMIS49587和NCN49597等。其中,AMIS-30585和AMIS-49587均基于ARM7内核微控制器(MCU),仅支持AC工作,每通道最大波特率分别为1.2k和2.4k;新推出的NCN49597基于ARMCortexM0内核MCU,同时支持AC及DC工作,每通道最大波特率达4.8k,支持CenelecA、B、C及D波段,且提供可编程软件。还预计将于2012年下半年推出在NCN49597基础上还集成功率放大器功能的NCN49599PLC调制解调器。
  这些强固的窄带PLC调制解调器嵌入了PHY+MAC,符合严格的国际标准(FCC、CENELEC、IEC61334-5-1),可在低压和中压网络上运行,提供最佳的物料单(BOM)成本和极低的能耗。
