Analysis of the Precise One-Dimensional Personnel Positioning Technology Scheme for Mines and Tunnels

I. Scheme Overview

The personnel positioning system for mine roadways and tunnels relies on advanced UWB (Ultra-Wideband) positioning technology to achieve a positioning accuracy of up to 30 cm. Through means such as electronic fence management, this system enables real-time personnel positioning, strengthens the control over hazardous areas, and effectively prevents safety accidents. In emergency situations, it can swiftly respond to rescue efforts, building a solid defense line for personnel safety.

II. Detailed Description of the Positioning Scheme

This scheme adopts high-precision UWB positioning equipment. A single base station board integrates two base station modules, and a single base station can accomplish one-dimensional positioning. This significantly reduces the number of base stations deployed, and the base stations can intercommunicate as soon as they are powered on. It offers a variety of interface options such as TTL/485/Rj45, allowing for easy integration with various back-end systems. It boasts notable advantages including simple deployment, system stability, and controllable costs.

III. Core Advantages of the Scheme

(A) Real-Time Positioning and Tracking

• Real-time tracking of personnel positions to dynamically grasp their movements.
• Support for querying the specific locations of personnel based on card numbers, names, etc.
•  

(B) Electronic Fence Protection

• Flexible setting of hazardous areas (such as excavation faces) and alarm rules.
• Alarm management for personnel approaching hazardous areas to ensure safe operations.
•  

(C) SOS Alarm and Paging

• On-site personnel can send SOS alarms via buttons on positioning tags, with real-time notifications.
• The monitoring room/back end can initiate calls to specific individuals or all personnel.
•  

(D) Historical Trajectory Management

• Long-term storage of personnel movement trajectories to provide decision-making support for incident handling.
• Support for playback of personnel activity trajectories within specified time periods based on card numbers and areas.
