针对智能空间移动目标定位的要求,在现有的智能空间无线传感器网络平台基础上,利用CC2431片上系统构建了一种基于Z-Stack的智能空间定位系统。详细分析了定位系统各节点的工作过程,剖析了基于命令簇的系统运行机制,给出了定位系统的命令簇信息格式。定位实验结果表明该定位系统能够满足智能空间中位置感知服务、移动目标跟踪等的应用要求。
In order to meet the requirements of moving target localization in smart space, a Z-Stack-based intelligent spatial location system is constructed by using the CC2431 system-on-chip based on the existing smart space wireless sensor network platform. The working process of each node in the positioning system is analyzed in detail. The operation mechanism of the system based on the command cluster is analyzed. The command cluster information format of the positioning system is given. The experimental results show that the positioning system can meet the application requirements of location-aware services and moving target tracking in smart space.
