Firstly, a panoramic sensing system for substation equipment is built based on edge computing, and an edge computing server is deployed in the substation to process the massive data obtained from multisource monitoring nearby. Then, the improved YOLOv4 network is used to detect the equipment state in the substation, in which the Squeeze-and-Excitation attention module and deep separable convolution are used to optimize the YOLOv4 network. Finally, based on the status image of substation equipment, the health status of equipment is evaluated on the panoramic platform of substation combined with the characteristics of multisource data, and four states are divided according to the evaluation criteria. Based on the selected dataset, the experimental analysis of the proposed method is carried out. The results show that the index values of accuracy, recall, and mean precision are 91.53%, 93.07%, and 92.28%, respectively. The overall performance is better than other methods and has certain application value.<\/jats:p>","DOI":"10.1155\/2023\/9194712","type":"journal-article","created":{"date-parts":[[2023,4,20]],"date-time":"2023-04-20T16:59:06Z","timestamp":1682009946000},"page":"1-12","source":"Crossref","is-referenced-by-count":3,"title":["Panoramic Assessment Method of Substation Equipment Health Status Based on Multisource Monitoring and Deep Convolution Neural Network under Edge Computing Architecture"],"prefix":"10.1155","volume":"2023","author":[{"given":"Zhu-xing","family":"Ma","sequence":"first","affiliation":[{"name":"State Grid Hebei Extra High Voltage Company, Shijiazhuang, Heibei 050070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li-shuo","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Grid Hebei Extra High Voltage Company, Shijiazhuang, Heibei 050070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hao","family":"Gu","sequence":"additional","affiliation":[{"name":"State Grid Hebei Extra High Voltage Company, Shijiazhuang, Heibei 050070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zi-zhong","family":"Xin","sequence":"additional","affiliation":[{"name":"State Grid Hebei Extra High Voltage Company, Shijiazhuang, Heibei 050070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhe","family":"Kang","sequence":"additional","affiliation":[{"name":"State Grid Hebei Extra High Voltage Company, Shijiazhuang, Heibei 050070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4645-8941","authenticated-orcid":true,"given":"Zhao-lei","family":"Wang","sequence":"additional","affiliation":[{"name":"State Grid Hebei Extra High Voltage Company, Shijiazhuang, Heibei 050070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"issue":"8","key":"1","doi-asserted-by":"crossref","first-page":"230","DOI":"10.1016\/j.egyr.2021.01.075","article-title":"Analysis of ECT effect on accuracy of measurement and protection","volume":"7","author":"M.
