摘要
建模测试对无线传感器网络的研究以及相关商用产品的开发起着至关重要的作用。描述了用于监控无线传感器节点定位功能的测试平台的工作过程,构建了基于ARM嵌入式系统的无线传感器网络。采用相对定位方法,确定网络内各节点的相对位置,降低误差,以符合精度要求。分析了在C/OS-II操作系统的调度下,传感器节点利用GPS模块进行相对定位的流程,并对网络状态的显示界面作了相应介绍。利用该平台对传感器网络进行测试,所得定位数据符合实际情况,获得了预期的结果。
Modeling and testing are ofgreat importance to the research ofwireless sensor network and development ofrelated commercial products. The working process of the test platform for monitoring the positioning function of wireless sensor node is described.A wireless sensor network based on ARM embedded system is built. Relative positioning method is adopted to achieve the relative locations of nodes in the network in order to reduce the error and fulfill the requirement of precision. The process of relative positioning using the GPS module, under the schedule of C/OS-II operating system, is analyzed, with a brief introduction to the display interface of the network status. Expected results are achieved by testing the sensor network on this platform and the positioning data achieved is identical to actual conditions.
