摘要/Abstract

摘要： 在工业场景中，复杂无线环境对定位网络的影响导致定位存在实时可靠性差、精度低的问题.基于此，本文设计了在信标节点异步情况下支持TDOA（Time Difference-Of-Arrival）测量的确定性定位网络模型（ASync-DetNET），同时提出了适用于ASync-DetNET的节点感知模型和定位模型.通过简化了定位节点对数据信息的获取方式，合理调度通信资源，使得能够满足不同精度的定位需求，在保障定位精度的前提下，提高定位的实时可靠性.本文在实际搭建的面向复杂工业环境的UWB（Ultra-WideBand）室内定位系统中进行测试，结果表明文中方法能够在一定程度上提高了定位精度，保证定位的确定性.

Abstract: In the industrial environment,the influence of the complex wireless communication on the localization network leads to poor real-time reliability and low accuracy of localization.This paper proposes the deterministic localization network model for TDOA (time difference-of-arrival) measurement in the case of asynchronous anchor nodes called ASync-DetNET.After that,we propose the sensing model and localization model,which can adapt to ASync-DetNET.These models can simplify the way of obtaining data information,comply with various requirements of localization accuracy and guarantee the real-time reliability with reasonably communication resources scheduling.Subsequently,we implement a localization system with ultra-wideband signals for complicated environment and finally we estimate the influence of the ASync-DetNET on the localization.The experiments show that the proposed models can improve the accuracy of localization and guarantee the deterministic of localization.
