Antecedentes del proyecto

An open-pit coal mine has deployed eight unmanned mining trucks to transport coal from the mining site to the unloading point. The mining environment is harsh, with high dust levels and severe vibrations. Each truck has a 50-ton load capacity, placing extremely high demands on the reliability and real-time performance of the onboard equipment. The project selected the Xingchuang Yilian SV910 dual 5G vehicle-mounted Ethernet gateway as the core communication and data hub to ensure the stable operation of the unmanned mining trucks around the clock.

 

Device connection method

Each mining card uses the SV910 as its core, enabling one-stop access for all equipment on the vehicle:

• Six vehicle-mounted Ethernet ports and two M12 industrial gigabit Ethernet ports connect to LiDAR, millimeter-wave radar, surround-view camera, vehicle-mounted industrial control computer, and backup interfaces, efficiently carrying point cloud and high-definition video streams.
• The three-channel CAN bus directly connects to the mining truck chassis control system, enabling real-time and reliable transmission of control commands such as throttle, brake, and steering.
• It adopts M12 aviation locking connectors , which are dustproof, waterproof, vibration-resistant and loosening-proof, suitable for the long-term bumpy and high-dust environment of mining areas, and prevent connector loosening and oxidation failure.

Dual 5G redundancy and multi-network aggregation

The SV910 adopts a dual 5G independent module architecture , supporting dual-SIM link redundancy and bandwidth aggregation.

• The primary and backup SIM cards can be from different operators, and they can automatically and seamlessly switch when the signal deteriorates , ensuring no disconnection in areas with weak networks, slopes, tunnels, etc.
• In multi-network aggregation mode, the bandwidth of the two cards is superimposed to stably support high-bandwidth services such as multiple video streams, radar point clouds, and control commands, ensuring that the upload speed and real-time performance meet the standards.
• It supports remote management , enabling remote activation, switching, and configuration, significantly reducing on-site operation and maintenance costs in mining areas.

NTRIP high-precision positioning + PTP nanosecond synchronization

Unmanned mining trucks have stringent requirements for positioning and timing accuracy, and the SV910 provides dual protection:

• It supports NTRIP differential positioning , connects to the mining area base station to achieve centimeter-level positioning , and has a lane keeping error of less than 5 centimeters, meeting the needs of precise driving on narrow roads.
• Built-in TSN+ PTP/GPTP hardware time synchronization enables nanosecond-level time synchronization of radar, camera, domain controller, and chassis , ensuring data alignment without drift and more precise control.
• The system operates continuously without deviating from the route or experiencing positioning failures, ensuring the safe operation of heavy-duty mining trucks.

Adaptability to harsh environments

The SV910 is designed according to industry standards and is fully adapted to extreme working conditions in mining areas.

• Wide operating temperature range , fanless fully enclosed passive cooling, eliminating the risk of dust blockage and failure.
• DC 9~48V wide voltage dual redundant power supply with multiple protections against overvoltage, overcurrent, and reverse connection, suitable for complex vehicle power supply environments.
• With a metal body, high-level protection, and resistance to shock and electromagnetic interference, it can meet the requirements of continuous unmanned operation 24/7.

V2X vehicle-to-infrastructure cooperation and platooning operations

The SV910 integrates CV2X ‑vehicle-to-everything (V2X) technology , enabling it to function without relying on base stations.

• The SV910 deeply integrates 5G-V2X with a built-in HSM encryption chip , fully supporting multi-scenario interaction across vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-person (V2P), and vehicle-to-cloud (V2C) interfaces. Its V2X-PC5 interface features direct communication, eliminating the need for base stations, networks, and data charges, enabling wireless direct connection to roadside RSUs (Roadside Units). This achieves non-line-of-sight perception, with a direct vehicle-to-vehicle communication distance exceeding 500m, ultra-low latency, and high reliability, significantly improving the safety, efficiency, and collaborative capabilities of autonomous driving.

Real-time monitoring, scheduling, and operation and maintenance

The dispatch center uses the SV910 to achieve full vehicle status visualization:

• Real-time location, speed, load, battery level, sensor status, and network quality are all readily available.
• Multi-channel video transmission in real time can detect road obstacles and landslide risks in advance, enabling rapid intervention and response.
• Built-in logs and local storage allow for backtracking and analysis in case of failure, quickly locating issues such as loose network cables and signal attenuation.
• Admite FOTA remote upgrades and remote diagnostics , making the operation and maintenance of unmanned vehicle fleets more efficient.

 

Network monitoring and protection

The SV910 features built-in intelligent network monitoring , providing real-time monitoring of signal strength, latency, and packet loss rate.

• Predicting network degradation before it occurs allows for automatic switching or aggregation to ensure uninterrupted critical business operations.
• The dispatch center can view the status of the entire network in real time, provide early warnings, and take proactive measures to avoid parking losses due to network outages.
• Since its inception, the project has been operating stably , ensuring transportation efficiency and operational revenue.

 

As a highly reliable vehicle-mounted communication platform designed for unmanned operation scenarios, the Xingchuang Yilian SV910 ‑provides a stable, secure, and scalable communication foundation for unmanned transportation in mines, featuring dual 5G redundancy, vehicle-mounted Ethernet, centimeter-level positioning, nanosecond synchronization, automotive-grade protection, and CV2X collaborative capabilities. This case fully demonstrates that in extreme industrial environments, a highly reliable vehicle-mounted gateway is the core guarantee for the safe operation, efficient scheduling, and commercialization of unmanned mining trucks, and also provides a mature and referable solution for the comprehensive unmanned transformation of smart mines.
