Wireless Positioning System for Tunnel Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In tunnel construction, the existing wireless positioning systems require frequent measurement of base station coordinates as trolleys move, increasing the workload for construction personnel due to the need for repeated coordinate measurements.
Innovation Solution
A wireless positioning system using ultra-wideband (UWB) positioning devices, including tags and base stations, that communicate wirelessly, with a server processing ranging values to determine accurate coordinates, reducing the need for frequent measurements by using triangular positioning and least squares methods, and adaptive positioning to maintain accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If base station coordinates are manually measured repeatedly when trolleys move, then positioning accuracy is maintained, but the workload of construction personnel increases
Solution Approach 1:
The system enables self-service positioning by equipping trolleys with mobile base stations that automatically perform positioning calculations using their own coordinates and ranging values, eliminating the need for manual coordinate measurements by construction personnel while maintaining positioning accuracy
Solution Approach 2:
The patent replaces manual mechanical measurement operations with an automated electronic positioning system that uses wireless communication, ranging value calculation, and automatic coordinate updating to determine positions, thereby reducing human workload while preserving measurement precision
2Measurement precision
If base station coordinates are frequently updated manually, then positioning accuracy is improved, but time consumption increases
Solution Approach 1:
The system implements continuous positioning by having mobile base stations on trolleys continuously obtain ranging values from fixed base stations and automatically update their coordinates in real-time, eliminating the need for intermittent manual measurements and reducing time consumption while maintaining continuous positioning accuracy
Solution Approach 2:
The system performs preliminary positioning setup by installing mobile base stations on trolleys beforehand, which then automatically handle all subsequent positioning operations including obtaining ranging values and calculating coordinates, eliminating the need for repeated manual coordinate updates and reducing time consumption

AI summary
The present disclosure provides a wireless positioning method as well as a server and a storage medium with the same. The method includes: obtaining a current ranging value between a first positioning device and a second positioning device, where there is no obstruction between the first positioning device and the second positioning device; determining a distance of the first positioning device and the second positioning device in a depth direction of a tunnel based on the current ranging value; and obtaining a current coordinate of the second positioning device based on the distance. In the above-mentioned manner, the automatic updating of the coordinate of the reference base station in the tunnel can be realized, the times of repeated measurements of the base station are reduced, thereby improving the construction efficiency of the tunnel and saving working loads.
