Title: Ke Chen and 3D Positioning for Subway Construction

Introduction

Ke Chen is an inventor based in Chengdu, China. His patent work includes a method for locating personnel or equipment in a subway construction shaft using ultra-wideband (UWB) positioning technology.

Latest Patents

Chen 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 and records the locations of UWB base stations installed on different levels. It gathers ranging data from a positioning tag, filters out erroneous measurements, and divides the coordinate space into equal cube-shaped grids. For each grid, selected base stations and their ranging data are used to estimate the tag’s position. The method then uses voting across the grid-based position records to determine a final coordinate.

Career Highlights

Chen is associated with China Railway Engineering Services Co., Ltd. His patent addresses the practical challenge of obtaining reliable three-dimensional positioning data in a subway construction environment.
