ZigBee2006
说明: 德州仪器(TI)宣布推出业界首款带硬件定位引擎的片上系统(SoC)解决方案 CC2431,以
满足低功耗 ZigBee/IEEE802.15.4 无线传感器网络应用的需求。这款来自 Chipcon 产品系列
的器件可满足多种应用要求,其中包括资产和设备跟踪、库存控制、病患监护、远程控制、
安全监控网络等应用,此外,TI领先的 ZigBee协议栈 Z-Stack 还提供有关支持。
CC2431 建立在业界首款针对低功耗 RF 应用的 SoC 解决方案 CC2430 的基础之上。上
述两款器件将业界领先的CC2420 RF收发器内核与增强型8051微控制器的出色性能完美结
合,具有高达 128kB 的闪存、8kB的 RAM 以及许多附加功能,而这一切仅采用一个 7 毫米
x7 毫米小型封装就实现了。
CC2431基于RSSI(Received Signal Strength Indicator)的定位引擎能根据接收信号强度与
已知 CC2430参考节点位置准确计算出有关节点位置,然后将位置信息发送给接收端,如电
脑、PDA、手机等。相比于集中型的定位系统,RSSI 功能降低了网络流量与通信延迟,在
典型应用中可实现 3 至5 米的精度。 (The CC2431 is a true System-On-Chip (SOC)
for wireless sensor networking ZigBee™ /
802.15.4 solutions with location detection
engine hardware onboard allowing location
accuracy of around 3 meters or less. It
enables ZigBee™ nodes to be built with very
low total bill-of-material costs. The CC2431
combines the excellent performance of the
leading CC2420 RF transceiver with an
industry-standard enhanced 8051 MCU, 128
KB flash memory, 8 KB RAM and many other
powerful features. Combined with the industry
leading ZigBee™ protocol stack (Z-Stack™ )
from Figure 8 Wireless/Chipcon, the CC2431
provides the market’s most competitive
ZigBee™ solution.
The CC2431 is highly suited for systems where
ultra low power consumption is required. This
is achieved by various operating modes. Short
transition times between these modes further
ensure low power consumption. )

NonLinearGranger
经济学家开拓了一种试图分析变量之间的格兰杰因果关系的办法,即格兰杰因果关系检验。该检验方法为2003年诺贝尔经济学奖得主克莱夫·格兰杰(Clive W. J. Granger)所开创,用于分析经济变量之间的格兰杰因果关系。他给格兰杰因果关系的定义为“依赖于使用过去某些时点上所有信息的最佳最小二乘预测的方差。”(granger causality test)
