摘要
为解决智能小区ZigBee信号传输效率低和能量消耗大的问题,研究了ZigBee信号在智能小区中的高效安全传输方法。在对CC2530、CC2430和JN51xx优劣的分析基础上,提出了采用大小功率ZigBee模块相结合的改进算法。实验结果表明,改进后的算法不仅能保证ZigBee网络的高效性和低能耗特征,并且能提高网络信号传输的安全性。该方案具有高可行性和优越性,以某小区为例计算结果表明,与无线传输比较,改进后的算法可节省成本34.7%。
To solve the problem of poor efficient and high-energy-consumption of ZigBee signal transmission in the intelligent community, the safe and efficient transmission of ZigBee signal is studied based on experiments. And an improved method that combines lower-power ZigBee module with high-power ones is presented based on the analysis of the the products of CC25xx, and the series of JN51 xx modules. Research shows that the improved algorithm has guaranteed the efficiency and low energy consumption and improved the safty of the Zigbee net. The improved algorithm gains high feasibility and superiority, saving cost by 34. 7% in one community
