Introduction

Qibin Wang is an inventor associated with Chengdu, China, and China Railway Engineering Services Co., Ltd. His patent work addresses positioning technology for subway construction sites.

Latest Patents

Wang is credited with 1 patent: “Method and System for Three-Dimensional Positioning in a Subway Construction Site, and Medium.” The invention describes establishing a three-dimensional coordinate system for a shaft area and locating UWB base stations across its different levels. The system measures the distance between a positioning tag and the base stations, filters erroneous measurements, and divides the coordinate space into equal cube-shaped grids. It then uses selected base stations and the center point of each grid to generate position records, before determining the tag’s final coordinates through voting across those records.

Career Highlights

Wang’s listed invention applies UWB-based positioning and data filtering to the practical challenge of locating equipment or personnel within a multilevel subway construction shaft. The approach combines measurements from multiple base stations with grid-based calculations to estimate a reliable position.

Collaborations

Wang’s listed coworkers include Ke Chen and Suimei Liu. The patent information provided does not specify their individual roles in the invention.

Conclusion

Qibin Wang’s patent focuses on improving three-dimensional positioning at subway construction sites through UWB measurements, error filtering, and grid-based voting.
