Integrated Utility Tunnel Coverage and Positioning

Utility tunnels and tunnels present unique environments, making personnel safety assurance and improved management efficiency core requirements. Maxon's personnel positioning system integrates advanced positioning technologies (WiFi, UWB, etc.) with a visual management platform, combining communication, sensor, and computer technologies to achieve comprehensive monitoring and management of personnel and materials within utility tunnels/tunnels, providing strong support for personnel safety protection and optimized management efficiency.

Project Overview

Application Scenarios: Focusing on enclosed or semi-enclosed special scenarios such as integrated utility tunnels and tunnels, providing services for core needs such as personnel safety monitoring and material management.

Core Objectives: To achieve real-time location tracking, trajectory tracing, safety alarms, and electronic roll call functions for personnel and materials, reducing safety risks and improving management efficiency through visual management.

System Architecture: Covering the presentation layer (real-time monitoring, trajectory tracing, etc.), the alarm layer (electronic fence, SOS alarm, etc.), and the application layer (electronic roll call, dispatching, etc.), supporting multi-terminal access and hierarchical permission management.

Project Challenges

Environmental Limitations: Utility tunnels/tunnels are often long, narrow, and enclosed spaces with curves and obstructions, requiring high demands on positioning signal transmission and coverage stability. 

Accuracy Adaptation: Different scenarios have varying demands on positioning accuracy (centimeter level, decimeter level, meter level, area level), requiring a balance between accuracy and cost-effectiveness.

Security and Compatibility: Data transmission and storage security must be ensured, while also being compatible with various positioning terminals (UWB, Bluetooth, WiFi, mobile phones, etc.) and different brands of security monitoring equipment.

Special Scenario Adaptation: Some utility tunnels/tunnels have explosion-proof requirements, and the equipment must meet stringent industrial-grade protection and explosion-proof standards.

Solution

Positioning Technology Selection

Based on accuracy requirements, Maxon flexibly combines technologies, using WiFi and Bluetooth positioning for meter-level/area-level positioning, and UWB for centimeter-level positioning, adapting to different scenario needs.

Hardware Deployment and Product Configuration

Deployment Scheme: Using a one-dimensional positioning mode, one positioning AP is installed every 100 meters in the utility tunnel/tunnel, with additional base stations at curves for compensation; supporting various installation methods such as ceiling mounting, pole mounting, and wall mounting.

Core Hardware: Includes industrial-grade APs (MX5012A series, IP68 protection rating, transmission distance 0-200m), explosion-proof APs (MX811/MX911 series, Ex d IIB/IIC explosion-proof rating), and WiFi positioning tags (supports clip-on wearing, one-button SOS emergency call, and buzzer alarm).

System Function Implementation

Visual Management: Supports 3D map display, floor switching, rotation and zooming, real-time display of personnel/material locations, and supports quick search.

Security Control: Establishes static electronic fences to implement boundary crossing, illegal intrusion, and loitering alarms; supports multiple alarms such as one-button SOS alarm, low battery alarm, and fall detection alarm, linked with sound and light alarms and video surveillance.

Data Management: Supports historical trajectory tracking, electronic roll call (timed/temporary tasks), data reports can be exported, and alarm information is permanently stored.

Permissions and Security: Uses HTTPS transmission, password encryption storage, and other technologies, with hierarchical and differentiated management of user permissions to prevent data leakage and illegal operations.

Project Advantages

Strong Adaptability: Supports multi-precision positioning technology and multi-terminal access, adapting to the environment and precision requirements of different pipe corridors/tunnels, and explosion-proof equipment meets the requirements of special scenarios.

High Security: Multiple alarm mechanisms and security monitoring linkage, encrypted data transmission and storage, and industrial-grade protection (IP68) ensure stable operation of equipment in harsh environments.

Efficient Management: The visual platform intuitively presents the status, electronic roll call and trajectory tracking functions reduce labor costs, and data reports support decision optimization.

Good Scalability: Supports map POI editing, batch import and export of terminals, and IoT function expansion, allowing for the addition of new functional modules and equipment as needed.

Case Sharing

The project has been implemented in pipe corridor and tunnel scenarios in multiple regions, with typical cases including pipe corridors and tunnels in Shiyan Hubei, Guangzhou, Hangzhou, Nanjing, Xi'an, Tibet, and Tianjin, covering various types of pipe corridor/tunnel projects across the country, stably achieving the goals of personnel safety monitoring and improved management efficiency.
