To reduce the negative impact of the maintenance of high-voltage circuit breakers on the power system, a forecasting method of overhaul cycle of high-voltage circuit breakers based on FGSO-BP is proposed. Through the analysis of historical overhaul cycle data, the change law of the overhaul cycle of the high-voltage circuit breaker is determined. It obtains the operation data of high-voltage circuit breakers, uses the iteration of FGSO-BP algorithm to extract the operation characteristics of high-voltage circuit breaker, and detects the fault type and degree of the circuit breaker through feature matching. Combined with the change law of the overhaul cycle of circuit breakers with different fault types, the final forecast results of the overhaul cycle are obtained. Compared with the traditional prediction method, it is found that the average prediction error of the optimization design method is reduced by 0.49h, which means that the optimization design method has obvious advantages in prediction accuracy.","PeriodicalId":305812,"journal":{"name":"International Conference on Electronic Information Technology","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128596570","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}

In order to make full use of the information contained in the discrepancy between the two branches, a Discrepancy-guided Fusion module is proposed at the feature level, in where the difference information between the features is used as a guide to promote the fusion of the features of the two branches.

In the process of DIC strain measurement, the commonly used gradient method and the local least squares method for displacement field fitting often produce large errors. To reduce the strain measurement error and improve the measurement results, a method of local weighted regression smoothing and moving means smoothing for displacement gradient is proposed to measure strain. The simulated Gaussian speckle is generated by a computer, and the reference image is deformed to verify the effect of these two methods, then compared with the gradient and local least squares methods. The results show that the strain field obtained by smoothing the displacement gradient has a good denoising effect, a more accurate solution, a more stable result, and less error.","PeriodicalId":305812,"journal":{"name":"International Conference on Electronic Information Technology","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117085984","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}

However, this also brings some security risks, such as arbitrary device publishing and subscription that can cause the IoT system to malfunction. Traditional MQTT access control methods, such as using access control lists (ACL), have some problems, such as security issues in storing permissions and matching efficiency. In this paper, we propose a blockchain-based access control method for IoT MQTT communication, which uses decentralized blockchain to store access control information, solves the problem of single-point failure, and ensures information security. To address the MQTT permission matching issue, we propose a Patricia Trie based adaptive priority topic search tree (PTST). This data structure optimizes the storage consumption of permission information and, for MQTT wildcard matching, uses an adaptive priority permission matching approach, which always searches from high to low priority, greatly improving the matching efficiency. Then we propose an access control model and process based on eXtensible Access Control Markup Language (XACML) standard. In the end, we perform performance testing and comparison with other data structures, and the results show good performance of PTST, demonstrating the feasibility of our scheme.","PeriodicalId":305812,"journal":{"name":"International Conference on Electronic Information Technology","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126316985","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}

Due to the extremely short wavelength of THz wave, ultra-massive multiple-input multiple-output (UM-MIMO) systems can be realized. The high array gain generated by UM-MIMO systems can overcome the limitation of THz communication distance. In UM-MIMO systems architectures, dynamic array-of-subarrays (DAoSA) architecture can dynamically adjust the connections between radio frequency (RF) chains and subarrays according to the channel state. In this paper, a hybrid precoding scheme of DAoSA architecture with low complexity and good performance is proposed. Hybrid precoding of UM-MIMO systems is optimized with the spectral-energy efficiency rate (SEER) maximization as the objective function. To reduce the computation complexity of optimization problem, the intractable original problem is decoupled into two subproblems that can be solved easily. Then, element-by-element (EBE) algorithm is proposed to solve the DAoSA hybrid precoding subproblem. Furthermore, to determine the connections of the switch es, a logistic chaotic searching algorithm (LCS) is proposed, which can obtain the global optimal solution without traversing repeatedly all connections under a fixed search space. Simulation results showed that the proposed DAoSA hybrid precoding scheme can achieve higher SEER than the existing papers.","PeriodicalId":305812,"journal":{"name":"International Conference on Electronic Information Technology","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134217454","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}
