摘要
通过对超宽带无线载波通信技术(UWB)的研究,采用TOF时间差进行定位的方法,利用信号源到各监测点的距离来确定信号发生的位置,重点解决矿井人员定位过程中定位误差大、定位不准确、实时性差等问题,同时对应用设计方案进行详细的论述,为矿井人员定位精准监测提供一种切实可行的技术。
In this paper,through the research of ultra wideband wireless carrier communication technology(UWB),using TOF time difference positioning method,using the distance from the signal source to each monitoring point to determine the location of the signal,the paper focuses on solving the problems of large positioning error,inaccurate positioning and poor real-time performance in the process of mine personnel positioning,and discusses the application design scheme in detail to provide reference for mine personnel.
