In this study, the theoretical analysis method is used to clarify the principle of Euler’s method to solve the ordinary differential equations firstly. Secondly, one typical example is set to compare the calculation accuracy and efficiency of the forward Euler formula, backward Euler formula, trapezoidal formula and modified Euler formula by self-programming. The results show that the calculation accuracy of Euler methods generally depend on the calculation step. As the step decreases, the calculation accuracy is gradually improved. In addition, the calculation efficiency and accuracy of the modified Euler method are very high, and the calculation accuracy of the trapezoidal formula and modified Euler method are quite close. However, the calculation accuracy of the forward Euler formula and the backward Euler formula can’t compare with those of the trapezoidal formula and the modified Euler method. Therefore, it is recommended to use the modified Euler’s method in engineering calculations, and the trapezoidal formula is secondly recommended.","PeriodicalId":124469,"journal":{"name":"2023 Asia-Europe Conference on Electronics, Data Processing and Informatics (ACEDPI)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132834686","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}

With the development of power system automation technology and computer technology, power quality monitoring system is widely used in many power consumption fields such as electric power, metallurgy, steelmaking and power plant, so as to monitor the power quality of load and protect some power sensitive loads such as computer system, communication system and medical system. At the same time, it can locate users affecting the power supply quality of power grid and order them to rectify. The existing monitoring system is not fully functional, especially the foreign monitoring system is expensive. Therefore, the research on the power quality monitoring system with complete functions and high cost performance has a good application prospect and market value. This paper designs a power quality dynamic monitoring system. Real time monitoring of power system is the main task of the system. Through real-time monitoring, the stable and safe operation of power system can be ensured. Based on the control core, this design adopts the algorithm to complete the long-term and real-time monitoring of the power grid. According to the modular method, this design divides the whole system into four parts: data acquisition, data processing, data communication and human-computer interaction. In the data acquisition part, the voltage and current signals in the power grid are completely collected into the digital signal processor, and then the processor calculates the data to obtain the parameter values of power quality. The processor also compares the calculated value with the standard value. If the actual data does not meet the requirements, it will give an alarm and remind, and the parameter results will be communicated with the host computer through the serial communication interface. This design can supervise the working state of the whole power grid, evaluate the level of power quality and prevent possible accidents in the power system.","PeriodicalId":124469,"journal":{"name":"2023 Asia-Europe Conference on Electronics, Data Processing and Informatics (ACEDPI)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133108709","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}

The explosive growth of video data makes it urgent for users to classify, browse and retrieve videos quickly and effectively. Content-based video processing and retrieval, which is dedicated to content analysis, semantic classification, index retrieval and storage management of videos by using IT, has attracted more and more attention of scientific research institutions and researchers. Sports estimation can reflect the temporal correlation between adjacent video frames. This paper adopts a simple and flexible sports estimation algorithm based on block matching. Key frame is a key image frame used to describe a shot. Based on the complexity of the shot content, one or more keyframes can be extracted from a shot. This paper studies several key technologies of semantic-based video content extraction and analysis. The research mainly focuses on how to automatically extract and analyze video content, and realize semi-automatic or automatic analysis and classification of video data to meet the needs of retrieval.

Underground pipelines are the lifeline of urban life, and the aging damage of pipelines over time brings serious harm to people’s lives. And many old pipeline construction drawings are lost, making it difficult to find the location of the pipeline, which brings great trouble to the construction staff. In order to find out the condition of pipelines under the ground in the city and to prevent major problems of underground pipelines from threatening people’s lives and causing significant economic losses to the society, a nationwide census and inspection of underground pipelines should be conducted to, on the one hand, increase the understanding of the structure of old pipelines and provide favorable information for urban construction; on the other hand, the abnormal condition of underground pipelines can be found in advance to remind the relevant departments to To make preparations and assist the relevant staff to carry out pipeline maintenance. Compared with the traditional detection methods, the efficiency of ground-penetrating radar is very high; and ground-penetrating radar can accurately detect the difference of underground objects and media, and can effectively detect the pipelines under the ground. Using ground-penetrating radar to ground detection without manual excavation and other operations, will not cause damage to the ground, is a non-destructive detection method. Therefore, we choose high efficiency, low cost, high accuracy and non-destructive ground-penetrating radar for ground detection. For this reason, the design of 3D cable line BIM parameter modeling system based on ground-penetrating radar identification results is studied in this paper.","PeriodicalId":124469,"journal":{"name":"2023 Asia-Europe Conference on Electronics, Data Processing and Informatics (ACEDPI)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121271488","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}

IoT technology has a variety of information sensors, powerful information collection and communication functions, and can provide advantages such as precise positioning. For a high-risk industry such as substations, it is also essential to monitor the safe operation of substations. Therefore, IoT technology is safe in substations. The application of operation monitoring has also become a research hotspot. In this paper, three positioning algorithms such as TOA, TDOA and AOA are proposed, and the positioning accuracy of TDOA is determined by the positioning accuracy measurement experiment. Therefore, TDOA can be selected for the positioning of the operator’s position by the monitoring system. The information transmission function transmits the location information of the operator to the monitoring background. When the operator exceeds the safe area, the system will alarm and remind to ensure the safety of the personnel.","PeriodicalId":124469,"journal":{"name":"2023 Asia-Europe Conference on Electronics, Data Processing and Informatics (ACEDPI)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131674953","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}
