A train black box is designed to withstand the shock and heat caused by a train wreck. The box-shaped device records data about the operation of train controls, the performance of train parts, and the direction and speed of a traveling train. Recorded data is similar to that found on an aircraft's flight recorder.
The Korea Railroad Research Institute (KRRI) said in a statement on July 8 that its researchers have developed a highly trustable train black box with an interface that is compatible with most train types and control systems. It was tested to be very durable against shock, fire, erosion by liquid, and physical penetration. "We will upgrade the technological competitiveness of the black box by adding artificial intelligence-based analytic tools to the device's data storage," said KRRI's senior researcher Kim Jae-won.
The railway institute said its new recording device showed the highest level of compatibility thanks to its interface designed to be compatible with different train communication systems. The new event recorder met international compatibility standards, KRRI said, adding technology was transferred to Rf-comm, a domestic train tech company.
