SINTRONES VBOX Series Ensures Reliable Communications

SINTRONES Robust On-Board Computers Ensure Reliable Communication for Rail Operators

SINTRONES’ VBOX Series Of Rugged Computing Platforms Provides An All-in-one Communications Back-up Solution For Rail Operators

Taiwan-based SINTRONES is an ISO 9001 and IRIS ISO/TS22163 certified producer of in-vehicle computing systems. This demonstrates the company’s commitment to continually enhancing its quality management systems and ensuring its products meet the ever-changing needs of the rail industry.

With years of engineering and product design behind it, SINTRONES is renowned for its high-quality, rugged yet compact computing platforms that meet international standards including – but not limited to – EN50155 and EN50121.

On-Board Computers

EN50155 Certification Ensures Safe and Stable Operation in Challenging Conditions

By passing a series of rigorous tests to achieve EN50155 certification, customers can be assured that SINTRONES’ VBOX series of on-board railway computers meet rigorous vibration, shock, input voltage range, electrical isolation, extreme temperature, humidity and EMC standards.

This guarantees that the computers are able to perform their functions safely and securely in a range of environments and conditions.

Isolated Power Input Design Meets Class S2 Interruption Requirements

SINTRONES’ design engineering team developed a customised power supply input feature for its in-vehicle computing systems, a critical step and a hard engineering requirement for the rail industry.

Thanks to the team’s hard work, the VBOX series offers a wide input range of 24~110VDC power input with isolation, which covers almost all railway application requirements.

In addition, its power surge protection and reverse polarity voltage protection prevents system damage if the input voltage is ever accidentally reversed.

Back-up System

An Operating Temperature Range of -40°C to 70°C – In Fanless Conditions

The VBOX series is also built with efficient thermal design. Testing has proven the computers can reliably operate in a wide range of temperatures from -40°C to 70°C, and even up to 85°C for short periods of time.

Vibration and Shock Protection

Robust and reliable M12 connectors are used to enhance system stability and protection, and feature fast-locking housing to resist high-shock and vibration loads. This enables the VBOX series to withstand vibration of up to 2.5GRMS and shock of up to 15G.

5G/LTE, GPS and Wi-Fi Functionality – An All-in-One Communications Solution

To ensure the safety of passengers and staff, railway operators require a reliable communication solution. In response to their needs, SINTRONES’ VBOX series has been developed to support 5G/LTE wireless, GPS and Wi-Fi functionality.

Whenever the primary wireless communication encounters instabilities or interference, the LTE wireless module can jump into action, providing the perfect back-up solution, even in challenging environments such as rail tunnels and mountainous areas where wireless signals can be weak.

GPS enables real-time location tracking of the train to the control centre and railway workers, while the computers’ Wi-Fi capabilities enable the uploading or downloading of data much quicker when approaching or in Wi-Fi enabled train stations or depots.

Italia Rail Chooses SINTRONES’ Computers for Its Wireless Communication Back-up System

Italia Rail wanted to implement a new wireless communications back-up system to ensure the safety of maintenance workers who spend much of their time working alongside its high-speed rail tracks.

The rail operator was looking for a solution that met industry standards as well as its own wireless communication (the need for LTE, GPS and Wi-Fi all in one) and power supply input requirements.

SINTRONES VBOX series was chosen due to the company’s ability to provide a customised supply input design, to satisfy the project’s wireless communication requirements and the fact that its product range met EN51055 certification standards.

The company’s VBOX-3620-M12X computing solution was implemented and installed on Italia Rail’s rolling stock back in 2018 with no network interruption, and has enhanced the efficiency of both the operator’s wireless network communication and the safety of its trackside workers.
