無線ZigBee智能能源鑰匙轉(zhuǎn)換

　　雖然許多人認(rèn)為交流電網(wǎng)是最普遍的數(shù)據(jù)網(wǎng)絡(luò)，但電力線網(wǎng)絡(luò)尚未廣泛成功?，F(xiàn)在，配電部門正在考慮在電表和能源消費(fèi)品（如家用電器）中增加智能，他們需要一種無處不在的通信方案來實(shí)現(xiàn)智能電網(wǎng)?？磥恚琙igBee智能能源標(biāo)準(zhǔn)將是答案，無線通道將是一個(gè)關(guān)鍵，雖然新的智能能源協(xié)議可能最終運(yùn)行在多種網(wǎng)絡(luò)類型之上。

　　ZigBee began as a low-power standard for wireless personal-area networks. It is based on the IEEE 802.15.4 standard and promulgated by the ZigBee Alliance （www.ZigBee.org）。 The mesh-networking-capable technology targets home automation and industrial networks.

　　The ZigBee Alliance has essentially completed the ZigBee Smart Energy Version 2.0 specification. The Version 2.0 spec is at the 0.9 draft level， and the ZigBee Alliance is no longer accepting public comments. ZigBee Smart Energy is poised to be the de facto standard for home-area networks （HANs）。 The standard is based on the Internet Protocol （IP）， and the ZigBee Alliance has developed the standard with input from other organizations， including NIST （National Institute of Standards and Technology）， the HomePlug Powerline Alliance， the Wi-Fi Alliance， and others.
