AI Technical Summary

Technical Problem

The existing railway tunnel construction management system cannot effectively perform real-time precise positioning of construction personnel, especially in the tunnel environment where signals are susceptible to interference.

Method used

A method and system for positioning a railway tunnel object are adopted, the system including a positioning tag attached to the monitoring object, a plurality of positioning base stations and a backend system. Positioning is performed through ultra-wideband wireless pulse signals, and the positioning data is sent to the backend system using wired and wireless transmission networks, one-dimensional, two-dimensional or three-dimensional positioning calculations are performed, and the positioning labels are displayed on the visual interface.

Benefits of technology

It realizes accurate positioning of construction personnel in various environments, improves the safety management capabilities of the construction site, and ensures real-time tracking and monitoring of construction personnel.

Abstract

The invention discloses a railway tunnel object positioning method and system.The system comprises positioning tags attached to all monitoring objects, multiple positioning base stations and a background system.The method comprises the steps that when the positioning tag attached to any monitoring object is located within the coverage range of any positioning base station, the positioning tags attached to any monitoring object are located within the coverage range of any positioning base station; sending a wireless pulse signal to each positioning base station corresponding to the coverage area of the positioning base station through an ultra wide band; each positioning base station generates current positioning data according to the wireless pulse signal sent by the current positioning label, and sends the current positioning data to a background system through a wired transmission network and a wireless transmission network; the background system performs positioning calculation of the current target dimension on the positioning label according to the current positioning data sent by each positioning base station to obtain the current position of the positioning label; wherein the current target dimension is one of one dimension, two dimension and three dimension; and the background system displays the current position of the positioning tag on a visual interface of the background system.
