Tunnel Utility Tunnel
In recent years, with the continuous expansion of the transportation network, China has become the country with the largest-scale tunnel engineering projects in the world. However, tunnel construction is carried out in harsh and challenging conditions, with frequent accidents. Moreover, tunnel workers often lack effective safety management and control measures in their daily operations, making occupational safety and safety management critical priorities in tunnel construction.
Based on the UWB precision Positioning System, by providing high-precision real-time positioning of personnel and construction vehicles, it is possible to track their locations and trajectories within the tunnel at all times. This not only facilitates efficient scheduling and personnel attendance management but also reduces risks such as vehicle derailment and collisions, ensuring the safety of tunnel construction workers and equipment, thereby enhancing the intelligent management of the tunnel construction process.
Background Requirements
In recent years, with the continuous expansion of the transportation network, China has become the country with the largest-scale tunnel engineering projects in the world. However, tunnel construction is carried out in harsh and challenging conditions, with frequent accidents. Moreover, tunnel workers often lack effective safety management and control measures in their daily operations, making occupational safety and safety management critical priorities in tunnel construction.
Solution Architecture
Functional Applications
Zero‑dead‑zone coverage of positioning signals
The Base Station boasts excellent RF performance and can be deployed at 600-meter intervals. Its dual-antenna design enables it to accommodate the curvature of tunnels, effectively mitigating signal attenuation caused by tunnel bends.
“Positioning + Early Warning” dual‑alert positioning device
Vehicle-mounted locators are deployed at both the front and rear of the vehicle, serving not only for vehicle positioning but also integrating collision‑avoidance functionality to provide proactive collision warnings. Meanwhile, the software platform can issue alarm notifications, implementing a dual‑layer early‑warning system.
“Active + Passive” Vehicle Collision Avoidance
By measuring the distance between the vehicle-mounted locator and the positioning Base Station, precise vehicle positioning is achieved. Meanwhile, the vehicle-mounted locators can also measure distances to one another; when the distance becomes too close, an automatic collision‑avoidance warning is triggered, integrating positioning and collision‑avoidance functions.
Anti-Collision Alarm Scheme and False Alarm Elimination
It adopts a split‑design architecture, with an onboard locator installed at both the front and rear of the vehicle, and includes in‑vehicle alarm‑management equipment. Users can customize alarm thresholds and whitelist settings based on vehicle length and specific operational needs, effectively reducing false alarms and enhancing management flexibility.
Tunnel Communication Solutions
The vehicle-mounted locator is equipped with an active collision-avoidance warning function that operates independently of positioning Base Stations or software platforms, relying entirely on the device itself to ensure rapid and accurate warnings.
System Expansion Solution
The system supports the convenient entry of new devices; by simply entering the device’s location information, the Positioning System can be expanded without requiring complex configuration.
Value Highlights
The Personnel Positioning System plays a crucial role in preventing overcapacity production, supporting emergency rescue operations, enabling leadership oversight of on-site shifts, managing special‑operation personnel, and tracking the attendance and location of workers inside the Tunnel Utility Tunnel. The significance of establishing a personnel positioning system for the Tunnel Utility Tunnel lies in leveraging advanced technological solutions to enhance safety management in tunnel projects, ensuring the safety of construction and maintenance personnel, and simultaneously improving operational efficiency, thereby providing comprehensive monitoring and management capabilities for tunnel construction and maintenance.
