To enhance the reliability of these valves, this study aims to develop a deep learning-based prognostics and health management (PHM) model. Past empirical methods have limitations, driving the need for data-driven prediction models. The proposed model monitors safety valve performance, detects anomalies in real time, and prevents accidents caused by system failures. The research focuses on collecting sensor data, analyzing trends for lifespan prediction and normal operation, and integrating data for anomaly detection. This study compares related research and existing models, presents detailed results, and discusses future research directions. Ultimately, this research contributes to the safe operation and anomaly detection of pilot-operated cryogenic safety valves in industrial settings.<\/jats:p>","DOI":"10.3390\/s24061814","type":"journal-article","created":{"date-parts":[[2024,3,12]],"date-time":"2024-03-12T12:14:40Z","timestamp":1710245680000},"page":"1814","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Deep Learning-Based Prognostics and Health Management Model for Pilot-Operated Cryogenic Safety Valves"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8280-3493","authenticated-orcid":false,"given":"Minho","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Computer and Information Engineering, Catholic University of Pusan, Busan 46252, Republic of Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6018-3692","authenticated-orcid":false,"given":"Hansaem","family":"Seong","sequence":"additional","affiliation":[{"name":"DH Controls Co., Ltd., Busan 46747, Republic of Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0562-351X","authenticated-orcid":false,"given":"Dohyun","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Computer and Information Engineering, Catholic University of Pusan, Busan 46252, Republic of Korea"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1483","DOI":"10.1016\/j.ymssp.2005.09.012","article-title":"A review on machinery diagnostics and prognostics implementing condition-based maintenance","volume":"20","author":"Jardine","year":"2006","journal-title":"Mech.
