System Composition
Intelligent Sensing and Interaction
Utilizing radar-visual fusion sensing, it achieves real-time tracking of key vehicle trajectories across the entire area, precise lane-level perception of critical events, and proactive event detection.
Based on the OpenHarmony highway distribution, it transforms traditional electromechanical "dumb terminals" into intelligent devices, introducing capabilities such as real-time status acquisition, "touch-to-connect" near-field direct connection, and electromechanical emergency linkage.
Intelligent Connectivity
It employs an industrial GPON/switch to build a fiber optic ring network, providing high-security, low-latency data backhaul based on network isolation technology.
It adopts a highly reliable dual-path fiber optic redundant network to support 24/7 online services.
Network management is real-time and visible, supporting remote rapid fault location and optimization.
Intelligent Hub
Integrated hyperconverged equipment allows for wide-environment deployment, integrating storage, computing, network, security, and AI full-stack capabilities. It features extremely simple deployment, out-of-the-box usability, and supports remote automated operation and maintenance, requiring no dedicated personnel.
Based on an IoT platform, it enables unified access and management of electromechanical equipment, real-time status monitoring, and unified business operation.
Smart Applications
Based on digital twins, a comprehensive intelligent tunnel management and control platform is built, integrating "intelligent sensing," "intelligent joint control," and "intelligent operation" to promote the intelligent upgrading of tunnel operation and management.
System Highlights
Rayvision Precise Sensing
Full-area real-time tracking of key vehicle trajectories; precise identification of critical events such as abnormal parking, collisions, and wrong-way driving, with event location accuracy reaching 5-10 meters.
Unified Equipment Management
The IoT platform widely supports various access protocols, enabling unified management of all devices, real-time acquisition of device status, and breaking down siloed technical barriers.
Proactive Event Reporting
Abnormal events are no longer passively detected but are now detected and proactively reported with second-level precision, improving handling efficiency and reducing accident rates.
Improved Inspection Efficiency
Handheld terminals based on the OpenHarmony highway distribution support near-field direct device connection, automatic detection and form filling, improving inspection efficiency by 2-3 times.
One-Click Electromechanical Control
Intelligent linkage of electromechanical systems such as fans, roller shutters, lighting, fire protection, lane lights, and dynamic speed limit signs; one-click policy deployment; response time compressed to the second level.
Simplify operation, maintenance, and development
Optical connections replace PLC cables, saving 90% on cabling and 60% on installation/maintenance time; HarmonyOS-based transformation unifies interfaces, protocols, and data standards, and the more universal language/tools facilitate development.
