This study also aims to add timestamps to power supply data to facilitate system maintenance.

Based on the characteristics of engineering data, this paper adopts the high-performance IoTDB time-series database in the Internet of Things (IoT). It designs metadata templates and engineering data encoding, optimizes storage methods to reduce storage pressure, and improves throughput to meet demands.

However, the power supply based on traditional PID control has problems of poor output voltage stability, slow response speed and large ripple. In order to improve the output voltage response speed and stability of the power supply, a BP-PID control strategy based on ADE optimization is proposed, which combines neural network and PID control. It adapts the PID parameters according to the output voltage situation, making the power supply have good robustness. For the problem of large output voltage ripple, a ripple disturbance suppression extended state observer based on bandwidth method is proposed to sample the DC voltage observation. The method of integrating the extended state observer effectively suppresses the ripple, thus improving the performance of the underwater detector and ensuring that the output voltage of the DC-DC buck converter is in the optimal state. Finally, the experimental results show that the proposed method can effectively improve the system output voltage stability, response speed and reduce the voltage ripple, and has good practical engineering application value.","PeriodicalId":518671,"journal":{"name":"2024 IEEE 4th International Conference on Power, Electronics and Computer Applications (ICPECA)","volume":"103 2","pages":"759-764"},"PeriodicalIF":0.0,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140530470","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}
