A team of undergraduate students of Ewha (advisor: Prof. Sang Beom Jun) won the gold prize at the ‘2020 Student Contest of Railway Works’ held on November 26. The ‘Student Creative Railroad Works Exhibition’ is a nationwide competition hosted by the Korean Society for Railway and sponsored by many railway-related institutions and companies - Ministry of Land, Infrastructure and Transport; KIPO(Korean Intellectual Property Office); Korea National Railway; KRRI(Korea Railroad Research Institute); TS(Korea Transportation Safety Authority); Seoul Metro.
The team members - Seongyoon Cho (the Department of Chemistry and Nanoscience), Yerin Yoon (the Department of Mathematics), and Jiyoung Lee (HOKMA college of General Education) - won the gold prize for ‘The wheel chocks removal alert,’ which based on Arduino. The ‘The wheel chocks removal alert’ is a notification system that allows a driver to remove the wheel chocks before operating the train. The system detects whether wheel cocks are removed by using infrared sensors. In addition, various sensors are used to create visual and auditory alerting functions.
The team focused on minor parts that are usually easy to overlook and came up with an idea to prevent subway accidents. They then realized the idea at a low cost by using Arduino and sensors. In addition, they focused on an alarming function, which is crucial for the work. By doing that, they were able to create their work within a short time.
Seongyoon Cho said, "The engineering field was an unfamiliar area, but it was a great opportunity to experience a new field." Yerin Yoon said, "I was worried because it was my first time participating in a contest. It was difficult yet rewarding to realize our ideas. Also, as a presenter, I was able to think deeper about our works and how to deliver our ideas." Jiyoung Lee said, "Through solving problems, I was able to experience the practicality of electronic engineering directly."
