Train Onboard Secure Computing Platform (EN50155)

Overview

The emergence and development of artificial intelligence (AI), the Internet of Things (IoT), and big data have provided the rail sector with opportunities to drive data intelligence with onboard computing platforms. Applications include: 

1. Driver and Passenger Behaviour Analysis

Integration of edge AI systems and onboard surveillance applications enables the detection and analysis of drivers’ and passengers’ behavior, triggering alerts in the event of potential risks. At the same time, it enhances passenger convenience by providing real-time updates on seat occupancy status.

2. Onboard Diagnosis and Predictive Maintenance

Through signal and data analysis, train operators can gain insights into the bogie or axle status via software, facilitating early problem resolution.

3. Cybersecurity

Besides implementing network segmentation to protect against potential threats, incorporating security features into onboard networking solutions is important for ensuring the integrity and confidentiality of data. Consider advanced security measures to effectively mitigate potential risks.

Solution

Axiomtek tBOX520 is a high-performance modular embedded system designed for demanding railway environments. Powered by 12th Gen Intel® Core™ i7/i5/i3 or Celeron® processors, it provides strong computing performance for applications such as onboard control, communication, and hardware firewall deployment. Its modular design allows system integrators to customize connectivity based on project needs, making it suitable for flexible and scalable railway system integration.

With two value-added module slots, Axiomtek tBOX520 supports flexible expansion options such as LAN ports, CANBus, and PoE. For firewall applications, VAM708 modules with M12 A-code LAN ports and LAN bypass can be added to support reliable network connectivity and uninterrupted operation. Certified to EN 50155 and EN 45545-2 standards, the tBOX520 is built to operate in harsh railway conditions, supporting a wide temperature range from -40°C to +70°C, 24 V to 110 V DC power input, and intelligent power management features including ACC on/off delay, shutdown delay, and over/under voltage protection.
