Gwangju Urban Railway Corporation Obtains Patent for Remaining Life of Automatic Train Control Device Components

[Asia Economy Honam Reporting Headquarters Reporter Park Seon-gang] Gwangju Metropolitan Rapid Transit Corporation (President Yoon Jin-bo) announced on the 24th that it has received a patent registration notification from the Korean Intellectual Property Office for the ‘System and Management Method for Confirming the Remaining Life of Automatic Train Control Device Components.’

Choi Jin-won (46), head of the corporation’s Vehicle Team, along with four others, began research in 2017 to resolve speed recognition errors that occur when the train receives speed codes sent from beneath the rails during train operation.

During operation, the electric train controls its speed by receiving speed codes through a device called the ‘Automatic Train Control Device Signal Board.’ If a malfunction occurs in this process, it can significantly impact the safe operation of the train.

After persistent research, the team focused on the fact that the remaining life of components affects errors in the ‘Automatic Train Control Device Signal Board’ and succeeded in devising a tester that can verify this.

At the same time, using this tester, they identified the causes of faults in the automatic train control device and found a method to perform maintenance independently, leading to the patent application.

With this patent acquisition, the corporation now holds a total of 16 intellectual property rights, including various patented technologies for safe train operation, utility models, and designs.

Yoon Jin-bo, president of Gwangju Metropolitan Rapid Transit Corporation, said, “This patent is the passionate result of employees who challenged themselves with a sense of problem awareness on site,” adding, “We will continue to make relentless efforts for the safety of citizens.”
