| 摘 要： | 无线定位系统在实际应用中常因环境中的电磁干扰及无线传感器网络节点自身软硬件工作状态突变等因素的影响，出现定位不准确或定位数据遗漏等瞬时故障。针对瞬时故障导致的基于TOF测距的无线定位系统定位失效，分别从TOF测距和通信两方面提出故障解决方案。实验结果表明，该方案可以有效地控制瞬时故障导致的系统定位失效，提高了无线定位系统定位有效率和精确度。

| Abstract: | In practice, there are some transient faults such as inaccurate localization and location datas missing in the wireless location system due to the environmental electromagnetic interference and the working condition mutation of the hardware and software in wireless sensor network nodes. This paper proposed a solution to solve the location failure caused by transient faults from TOF ranging and wireless communication. The experimental results demonstrate that the system positioning failures were effectively ... |
