Certification platform enables smart train system in Korea

LSIS was engaged in a national project to develop the Korean Radio-based Train Control System (KRTCS) for the unmanned remote control of trains via LTE wireless communication and WiFi, making it the first CBTC system in the world that uses both WiFi and LTE technologies. A key part of the KRTCS project was to attain SIL4, the highest safety grade in the rail sector, marking the first such certification for CBTC wayside and on-board systems in the country. 

In order to deliver a certifiable solution, LSIS needed a commercial off-the-shelf platform for delivering applications that have to meet the international railway software standard IEC62279. The company also needed a technology partner with extensive experience with similar challenges to help minimise risks and satisfy the project requirements.

LSIS selected VxWorks Cert Platform, part of the Wind River product portfolio of safe and secure OSs, along with the company's professional services. To meet the rigid safety requirements, Wind River provided support for the entire certification process in the development of a board support package, as well as the entire development lifecycle including plan, design, test, prototype development, verification and validation. With a comprehensive Wind River solution, LSIS successfully delivered an advanced smart train control system with SIL4 certification.

"Wind River not only provided us the long-term technical roadmap, but also demonstrated a long track record of successful software implementations in the rail and communications industry," said Yonggee Cho, Project Leader, LSIS. "Wind River holistically delivered on our core requirements, and had the expertise to systematically manage the entire process, from development to certification to minimise testing and validation risks."

"The successful implementation of VxWorks, along with the development of the BSP through services, and the systematic management of the certification process has led to the success of this project," said Dinyar Dastoor, Vice President and General Manager, Operating System Platforms, Wind River. "Wind River technology and services allowed LSIS to meet its critical project goals of reducing development time and certification risk."
