RTO 사고 예방을 위한 메타버스 기반 안전 서비스 플랫폼

Abstract

This paper implements a Metaverse-based safe operation service platform for safe maintenance and operation of RTO. A Regenerative Thermal Oxidation (RTO) is a device that prevents volatile organic compounds (VOCs) gas generated from chemical plants, paint production and coating manufacturing, and metal surface treatment from being discharged into the atmosphere. If the plant is operated 24 hours a day, the RTO also continues to operate. In order to operate safely and preserve accident prediction, guidance and safety education on equipment are necessary.
 Most of the 24-hour RTOs are long-distance, so if the equipment fails, there is a limit to immediate response, and an inefficient maintenance situation occurs. In particular, long-distance monitoring and safety training for operation are needed due to the immature handover caused by the aging trend of field personnel, complex equipment use, and personnel turnover.
 A virtual space is constructed based on a metaverse, and an assembly manual for equipment structure, circuit diagrams, component characteristics, and detailed composition is shaped in 3D using digital twin technology. To this end, 3D modeling technology generates a mesh based on the design data of the RTO equipment and generates a texture of the equipment based on the actual picture. Through the reconstructed 3D virtual space in the field for 3D virtual space configuration, the user's parts are tracked by delivering immersive low latency and high-quality data to remote XR devices, PCs, and smartphones based on multi-user. At this time, AR glass (smartphone) is used to share the location of the remote user with the site as location data.
 Most studies on the safe operation of RTO devices have focused on hardware safety through field monitoring and data acquisition for pressure, temperature, and VOCs emissions through sensor IoT. Most of the plants are located at a long distance, and the time to stop the plant for repair and repair work is limited. Accordingly, monitoring, which was previously operated as a 2D screen, is combined with 3D space to provide an intuitive and visible environment and efficiency.
 By predicting the failure state of the facility through metaverse-based monitoring, the efficiency of maintenance can be improved, and productivity and market competitiveness can be secured by minimizing downtime. In addition, education and training in virtual space reduces the risk of failure and maintains a high level of facility maintenance to establish a safe working environment. Therefore, the system's overall safety platform can cope with serious disasters and minimize environmental impacts such as gas leaks as well as equipment failures.
