ZigBee无线技术具有低功耗、低成本等诸多优点,很适合应用在控制类的家庭网络中。本系统在ARM9 STR912FW44X处理器上移植μCOS-Ⅱ操作系统和无线射频收发模块cc2430搭建网关开发平台。它很好地克服了传统网关架构下Zigbee传输速率的瓶颈,降低了资源和处理时间消耗,提高实时处理能力。通过验证,完全能够满足家庭网关的控制需求。
The new wireless technology ZigBee, which is very low in cost and power consumption, is quite suitable for home network specialized for controlling home appliances. This system is designed by replanting real time operation system μCOS-Ⅱ on the micro-controller STR912FW44X (based on ARM9 core) and on gateway development platform built up by wireless radio frequency receiving and transmitting module cc2430. This gateway fairly overcomes the bottleneck of ZigBee transmission rate under traditional framework, reduces the processing time and resources consumption, and enhances the real-time processing power. Experiment indicates that the ZigBee technology could sufficiently meet the requirement of normal family in cont rolling home appliances.
