Title: Youxing Wu and 3D Positioning for Subway Construction

Introduction

Youxing Wu is an inventor based in Chengdu, China, whose patent work addresses positioning technology for subway construction sites. His disclosed invention applies ultra-wideband (UWB) ranging and a grid-based voting method to estimate a positioning tag’s location in a shaft area.

Latest Patents

Wu is associated with 1 patent: “Method and System for Three Dimensional Positioning in Subway Construction Site, and Medium.” The method establishes a three-dimensional coordinate system for a shaft area and records the coordinates of UWB base stations installed at different levels. It gathers ranging data from a positioning tag, filters out erroneous measurements, and divides the coordinate system into equal cube-shaped grids. For each grid, the method selects a preset number of base stations and calculates a position record using their coordinates, the corresponding ranging data, and the grid’s center point. It then uses voting across the grid-based records to determine the tag’s final position.

Career Highlights

Wu is associated with China Railway Engineering Services Co., Ltd. His patent focuses on a practical construction-site challenge: determining position in a multi-level shaft environment using measurements from UWB base stations.
