High-Precision Indoor and Outdoor Integrated Positioning Solution for Open-Pit Mines

Requirement Analysis

Challenges in Safety Management
Collision accidents: Mechanical collisions are prone to occur during cross operations between personnel and vehicles, as well as between vehicles.
Unauthorized vehicle driving: Unlicensed driving, unauthorized driving, and speeding.
Unauthorized entry into hazardous areas: Staff may mistakenly enter dangerous areas such as hazardous material warehouses and oil and gas storage tank areas, resulting in safety accidents.
Low Operational Efficiency
Personnel and vehicle positioning: Unable to obtain the location distribution of personnel and vehicles for more reasonable task assignment to improve mining efficiency.
Vehicle trajectory restoration: Unable to review vehicle routes for reasonable optimization of driving routes and improved transportation efficiency.
Difficulties in Operation Management
Excessive number of personnel and vehicles: Difficult to accurately track and count the number of operating vehicles and personnel, making real-time monitoring of over-limit issues impossible.
Personnel tardiness and absenteeism: Tardiness and absenteeism occur during work, disrupting the normal operation of production processes.

Introduction to the Indoor & Outdoor Integrated Positioning System

System Overview

1.Scene Classification: The indoor-outdoor integrated positioning system covers both outdoor and indoor scenarios, adopting positioning technologies including satellite positioning, UWB positioning and Bluetooth positioning.

2.Implemented Functions: The system can realize functions such as personnel and vehicle positioning, personnel-vehicle collision avoidance, personnel-vehicle scheduling, population statistics, personnel attendance, electronic fencing, and personnel on-duty status monitoring.

3.Problem Solving: It greatly reduces the incidence of collision accidents during daily operations of enterprises; optimizes the assignment and arrangement of work tasks for personnel and vehicles; strengthens the management and control of key areas such as hazardous areas and confidential areas; monitors the real-time presence of personnel and vehicles in the mining area; and supervises the real-time on-duty status of personnel.

System Advantages
1.Centimeter-level ranging accuracy: Adopting UWB technology, it achieves high-precision positioning of 10 cm, effectively preventing collision accidents.

2.Millisecond-level alarm delay: The vehicle anti-collision equipment adopts on-board ranging calculation and alarm output. Compared with calculating in the server background and then sending alarm signals to the front end, the alarm trigger delay is greatly reduced.

3.High-precision integrated positioning: For indoor and outdoor integrated positioning scenarios, an independently developed trajectory continuity algorithm is applied, which restricts jitter and drift during indoor-outdoor positioning handover to a certain extent.

4.Rich interfaces for easy integration: The equipment is equipped with digital input/output and RS485 interfaces and provides embedded development tools, facilitating linkage and integration of functions in different business scenarios.
