摘要
气象温湿度的数据采集经常进行在一些距离分散,工作环境恶劣的境况中,节点因为能耗出现故障与死亡后无法及时为其进行能量补充;基于ZigBee无线传感网络进行数据传输,在路由协议中抛开先驱节点的列表计算,仅依靠数据更新进行冗余度降低,设计汇聚节点对温湿度数据进行中继转发;实际的系统测试中,网络的能耗较传统的方法降低了5%,数据延时限制在2.7s以内,数据丢包率为2.1%,数据测试的准确率大大提高,证明该方法的实用性与可行性。
Weather of the temperature and humidity data acquisition is regular in some distance to disperse, work environment bad situa- tion, node failure and death because energy consumption and not in time for the added energy. Based on the ZigBee wireless sensor network data transmission, routing protocol in the cast list of pioneer node calculation, rely on the data update for redundancy is reduced, the design of temperature and humidity data gathering node for relaying. The actual system test, the network energy consumption is the traditional method was reduced by 5%, data delay limit within 2. 7 S, data packet loss rate was 2. 1%, the accuracy of test data has been greatly im- proved, and prove that the method is practical and feasible.
