In the current stage, the Broadband Power Line Carrier HPLC technology has been widely applied for the access of distributed photovoltaic devices to perform data collection and transmission functions. However, due to the limitation of the HPLC networking method and communication mode, the current communication system exists problems such as long-distance node communication could not be covered, power line communication is susceptible to interference, and could not be safely and accurately controlled in real-time, which is difficult to achieve broad and reliable access of devices. Therefore, this paper proposes a novel concept that is using 4G technology to replace HPLC technology to help realize local communication in the smart distribution network. According to the practical test results, the current design could operate stably and efficiently which provides a practical reference for relevant research.","PeriodicalId":253792,"journal":{"name":"Conference on Optics and Communication Technology","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125553950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sun, Lianda Duan, Gaoju Li, Nana Lu","doi":"10.1117/12.2653434","DOIUrl":"https://doi.org/10.1117/12.2653434","url":null,"abstract":"The cost of operation and maintenance(O&M) has been one of the central budgets in the wind turbines' life cycle. In the final stage of the O&M work, the administrators must manually review the on-site photos to ensure the O&M is qualified, which is time-consuming and ineffective. To improve the efficiency and quality of O&M reviewing work while reducing its costs, we propose an auxiliary reviewing system to optimize the reviewing process. Our system architecture consists of data collection, analysis, and presentation modules. During day times, the data collection module will handle storing and organizing the photos of O&M. The data analysis module will perform duplicate image detection using the MessageDigest Algorithm 5(MD5) and missed image detections through the pre-trained ResNet50 deep learning model. The review results from the analysis module will be fully updated to the database after the analyzing process and rendered into graphs or tables on the webpage when required by the reviewers. Analyses are done in this paper to visualize the functions of each module of the proposed system. The experiment evaluates the performance of three deep learning models, including AlexNet, VGG16, and ResNet50, based on authentic on-site inspection images data from our \"first annual inspection\" dataset to determine which model yields the best image classification performance. The experimental result reveals that ResNet50 can reach the highest accuracy at 96.2% on the test dataset. Thus, we choose ResNet50 to train the image classifier of our data analysis module.","PeriodicalId":253792,"journal":{"name":"Conference on Optics and Communication Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131445508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It faces unprecedented research problems in physical optics, one of which is the single beam modulation mode, which greatly limits its large-scale application. A vortex beam carrying orbital angular momentum can theoretically generate an infinite variety of mutually orthogonal modulation modes. Applying it to imaging detection has the potential to bring richer information freedom while ensuring imaging resolution. In this paper, a vortex beam imaging model based on synthetic aperture method is proposed by combining vortex beam and synthetic aperture technology. Based on the basic principle of synthetic aperture and the theory of vortex beam orbital angular momentum, a synthetic aperture vortex beam imaging radar model is established. The data acquisition process of synthetic aperture vortex beam imaging is also deduced, and the phase angle position relationship in the echo data is analyzed. Finally, the range resolution and azimuth resolution of synthetic aperture vortex beam imaging under specific conditions are solved. Theoretical analysis shows that the rate of change of the topological charge of the vortex beam during the imaging process will have a great impact on the azimuthal resolution, which is consistent with the expected results. This paper lays a foundation for the follow-up research on vortex beam synthetic aperture imaging, and also provides a reference for the development of new radar technology.","PeriodicalId":253792,"journal":{"name":"Conference on Optics and Communication Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122447240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
