A Study on the Development of Augmented Reality Contents for Air Compressor of Railway Vehicles

Most of the maintenance and training of the railway vehicle of the Korean urban railway operator was conducted in the form of document-based manuals or internet-based e-learning. This training method is inefficient due to restrictions such as time, space, and human resource operation. This study is about the development of high-definition augmented reality content for innovation in existing education and training in accordance with the recent smart maintenance transition and digitalization of maintenance. To this end, the realistic contents for maintenance and training of commuter rail vehicle air compressors that can increase immersion and realism for railway vehicle maintenance workers were developed. In addition, a questionnaire evaluation was conducted on field applicability. Rail vehicle maintenance workers can receive maintenance support by efficiently accessing work information at the workplace using mobile devices. In order to evaluate the usability of the developed air compressor maintenance augmented reality content, a usability evaluation survey was conducted on 100 college students majoring in railway vehicles. The overall average score of the 6 questionnaire items for the content was 4.12 out of 5 points, which was very good. Therefore, this content is very useful for beginners in maintenance of railway vehicles and is considered to be very effective in using it for maintenance and training of air compressors in the workplace.
