Who is it for?

Operations, maintenance, management, and safety supervision personnel, as well as frontline inspectors working in enclosed spaces such as subway tunnels, municipal utility tunnels, and underground corridors.

What pain points does it solve?

Manual inspection: high-risk operations, time-consuming processes, and high rates of missed defect detection.

Conventional drones: susceptible to loss of control and disorientation without satellite signals, poor imaging in low-light conditions, short battery life, weak protection, and complex operation.

Product value?

Four core proprietary technologies, specifically tailored for enclosed spaces, achieving stable positioning, clear vision, long flight times, and intelligent operation.

Industry Pain Point: The Dilemma of Enclosed Inspections

Enclosed tunnels and comprehensive utility tunnels generally lack GNSS signals, have no light, and are subject to complex electromagnetic interference.

Manual inspection carries high risks and low efficiency: The fatality rate for accidents in confined space operations remains high. Inspecting a ten-kilometer tunnel manually is time-consuming and prone to missed defects.

Off-the-shelf general-purpose drones have significant shortcomings in adaptability: Radar-equipped models are unstable over long distances, while vision-based models have poor low-light and anti-interference performance. Most products can only be used in simple indoor environments and struggle to adapt to the complex, long-narrow conditions of tunnels.

How to solve the industry challenges of no signal, invisible hazards, inaccessible danger zones, and the inability to conduct routine inspections?

Aviation Traffic Control Technology I7: Four Technological Breakthroughs to Overcome Industry Bottlenecks

Aviation Traffic Control Technology, a subsidiary of Traffic Control Technology, officially launched the I7 dedicated drone for enclosed spaces at the World Drone Congress. It addresses pain points from four key dimensions: positioning, endurance, intelligent interaction, and full-chain ecosystem.

1. Advantage One: Satellite-Free Precision Positioning – No Getting Lost in Tunnels 

Conventional drones: In deep, long tunnels without satellite signals, they are highly prone to drift, loss of control, and crashes.

I7: Equipped with laser SLAM + optical flow fusion positioning, it operates stably in dusty environments and under strong electromagnetic interference. With millimeter-level hover accuracy, it can autonomously cruise even without GPS.

2. Advantage Two: Long Endurance & Full Protection – All-Weather Operation in Complex Conditions

Conventional drones: Have basic protection, incomplete obstacle avoidance, insufficient battery life (typically under 20 minutes), can only fly up to 500 meters, and cannot image in low-light environments.

I7: Features IP54 industrial protection, 360° omnidirectional obstacle avoidance, 40-minute no-load endurance, and multi-angle fill lights. A single inspection can cover 3 kilometers, with normal imaging capability even in low-light conditions.

3. Advantage Three: Drone-in-a-Box + Software Platform – Enabling Unmanned, Fully Automated Routine Inspections

Conventional drones: Rely on manual on-site presence for takeoff, landing, and control, making routine automated inspections impossible.

I7: Comes with an IP65 intelligent drone-in-a-box and drone management platform. It supports automated takeoff, landing, charging, and data backhaul, enabling remote coordination of multi-drone inspections and automated defect classification and archiving.

Application Scenarios: Tailor-Made for Enclosed Space Inspections

Leveraging Traffic Control Technology's deep expertise in rail transit and industrial operations and maintenance, the I7 drone is fully adaptable to various enclosed space operational scenarios.

Applicable Scenarios: Subway tunnels, municipal comprehensive utility tunnels, drainage culverts, mine roadways, hydropower station galleries, underground confined spaces, interiors of large industrial equipment, and various restricted operation areas.

The I7 is more than just an aircraft; it is a customized intelligent inspection solution for enclosed spaces. With precision positioning, long endurance, AI-driven intelligent control, and a fully automated closed-loop system, it enables standardized inspections and digital management of previously inaccessible confined areas. Traffic Control Technology, together with Traffic Control Aviation, uses hardcore technology to build a solid safety barrier for underground spaces.
