Technical Core – Defining the 5G T-Box "Central Nervous System"

In the era of "Software Defined Vehicles," a car's intelligence is no longer limited to mechanical control but lies in its seamless interaction with the digital world. The foundation for this is the hidden "Super Brain" inside the vehicle.

This segment focuses on the technical core of Sirun's 5G T-Box, revealing how its four functional centers make it an indispensable "digital lifeline" for Smart Connected Vehicles.

As the "Communication Brain" of Smart Connected Vehicles, Sirun's new-generation 5G T-Box plays a pivotal role in information exchange between the vehicle and the outside world. The Product Manager explained that the 5G T-Box is built around four functional centers:

High-Speed Data Transmission Hub (Monitoring Post): Leverages 5G's high bandwidth, low latency, and massive connectivity to provide lossless, smooth data pipelines for applications like in-vehicle HD video streaming and real-time video conferencing.

Vehicle Status Perception Hub (Surveillance Post): Collects and monitors key vehicle data (e.g., speed, system status) in real-time, reporting it to the cloud platform within milliseconds, providing the data foundation for vehicle health management and remote diagnosis.

Remote Control Execution Hub (Control Post): Enables precise remote vehicle control via mobile app, covering functions like keyless entry, engine start/stop, and air conditioning pre-conditioning, reshaping the human-vehicle interaction experience.

Information Security & Evolution Hub (Security Post): Incorporates high-level encryption algorithms for comprehensive data transmission and storage security, supporting safe and stable remote FOTA upgrades, giving vehicles continuous evolutionary vitality.

Building upon this core functional matrix, Sirun's 5G T-Box further expands its capabilities through cutting-edge technologies like V2X scenarios, high-precision positioning, digital keys, onboard Wi-Fi 6, and an Automotive Emergency Call System (AECS). It transcends traditional communication modules to become a comprehensive smart platform integrating connectivity, perception, control, and security, offering limitless potential for the continuous evolution of Smart Connected Vehicles.

Sirun's 5G T-Box is now in mass production, providing core communication capabilities for multiple mainstream automakers' Smart Connected Vehicle models.

Manufacturing Foundation – How Highly Automated Production Lines Forge Millimeter-Level Reliability

Even the most advanced design remains just a blueprint if it cannot be reliably delivered in manufacturing. For the 5G T-Box, which is critical to vehicle control and safety, reliability must be rooted in every detail of production.

CCTV's cameras went deep into Sirun's 5G Digital Smart Factory, documenting the relentless pursuit of "reliability."

Sirun's 5G Digital Smart Factory showcases a high-standard production line that integrates automation, digitalization, and intelligence. Key highlights include:

Micron-Level Precision Placement Process: The line uses ultra-precision SMT technology to reliably mount 02001 components (a mere 2.0mm x 1.0mm), ensuring thousands of components are placed with zero deviation on the PCB.

Full-Process Quality Detection System: Adhering to the "check at every step, quality closed-loop" philosophy. High-precision AOI optical inspection equipment, powered by advanced machine vision and deep learning algorithms, performs nano-level scanning and intelligent judgment of solder joint quality, accurately identifying and eliminating minute defects.

Extreme Environment Reliability Validation: Every unit off the line must undergo 200% performance testing and rigorous high-temperature aging simulation, operating at full load for 2 hours in temperatures from 60°C to 80°C, simulating long-term stability under extreme vehicle operating conditions.

 

This highly automated line boasts an automation rate of over 95%, achieves a breakthrough single-line daily capacity of 4000 units, improves efficiency by 100%, and reduces labor by 60%.

The value of this automated line lies not only in its efficient production and cost advantages but also in its integration of the "precision, inspection, rigor" philosophy throughout the entire manufacturing process. This internalizes "reliability" from a promise into the immutable DNA of every product, providing a solid quality guarantee for the large-scale commercialization of Smart Connected Vehicles.

The company's Vice President presented the platform's technical architecture, emphasizing four core values:

Full Protocol Stack Compatibility: Supports mainstream V2X protocol standards domestically and internationally, enabling seamless adaptation for global projects.

Active & Layered Security Defense: Integrates a dual encryption engine featuring Chinese cryptographic algorithms and the international TRSS 1.3 standard, achieving millisecond-level identity authentication and data encryption.

Edge Prediction & Decision-Making: Embeds high-performance GPU computing units, enabling complex algorithms like vehicle trajectory prediction and high-precision map matching to run in real-time at the edge.

Full-Link Data Traceability: The platform enables second-level scenario reconstruction and data playback, providing an accurate basis for accident analysis and function optimization.

As a core participant in the Smart and Connected Vehicle industry, Sirun actively contributed to the authorship of key industry documents including the "Vehicle-Road-Cloud Integrated System White Paper," "Smart Connected Vehicle Bluebook 2022," "Smart Connected Vehicle Bluebook 2023~2024," and "Smart Connected Vehicle Bluebook 2025." The company took a leading role in the functional design and architecture definition of the cloud control basic platform, promoting its standardization. Furthermore, for the four major scenarios of digital traffic signs, traffic signal control, traffic information release, and traffic warnings, Sirun proposed specific technical requirements covering information encoding, release scope, and direct communication latency, providing crucial support for the standardized development of Smart Connected Vehicles.

Sirun's new-generation V2XLink platform technology has already been deployed and validated at scale in national-level connected vehicle pilot zones, including Beijing, Shanghai, and Wuxi.

As a deeply entrenched front-load Tier 1 supplier, Sirun is collaborating closely with leading automakers. Evolving from a provider of smart connectivity products to a co-builder of the intelligent transportation ecosystem, the platform's demonstrated compatibility, security, and intelligence are key to solving industry collaboration challenges and realizing the value loop of "Vehicle-Road-Cloud."
