In view of the shortcomings of traditional capacitive corrosion sensor, a design of interdigital capacitive corrosion detection sensor for steel bar in concrete is proposed. Taking Q235 carbon steel as an example, this paper introduces the structure and working principle of the corrosion sensor, and analyzes the influence of material size and sectional area loss. The corrosion sensor consists of two comb-shaped electrodes made of, an acrylic substrate and an outer package made of hot glue. In order to verify its feasibility and stability, four corrosion sensors were embedded in the concrete and four concrete samples were prepared. The electrochemical accelerated corrosion test was carried out on four concrete specimens, and the relationship between the capacitance change of the corrosion sensor and the corrosion degree of the comb electrode was quantitatively analyzed by the weight-loss method. The experimental results show that the capacitive corrosion sensor designed in this paper adopts interdigital structure, which can greatly improve the sensitivity of the steel corrosion sensor and more effectively detect the corrosion state of Q235 carbon steel. In addition, the corrosion sensor is highly sensitive to the early corrosion and corrosion transition of Q235 carbon steel, which provides a reliable basis for timely and effective maintenance.","PeriodicalId":355442,"journal":{"name":"2023 2nd Asia Conference on Electrical, Power and Computer Engineering (EPCE)","volume":"34 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":"115418813","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}

To reduce the influnce of unbalanced power grid on BDFIG, the composition of instantaneous active and reactive power of BDFIG stator output under unbalanced power grid is deduced and analyzed, and a new approaching rate integral sliding mode variable structure with PI controller is proposed. The integral sliding mode variable structure is used to control the DC component of the output power of BDFIG under the unbalanced power grid. The double frequency fluctuation of power and the distortion of stator current are suppressed by PI control of stator current instruction. Finally, the influence of unbalanced power grid on BDFIG is reduced. In this article, the calculation principle of voltage positive and negative sequence decomposition for unbalanced power grid voltage is studied, and a fast positive and negative sequence decomposition method is designed to improve the delay problem of T/4 delay separation method, the BDFIG direct power control capability under unbalanced grid voltage is improved effectively.

However, optimized scheduling of variable volume water heaters must account for system uncertainties and meet the need for quick decision making. To tackle this problem, we propose a demand response optimization approach for variable volume water heaters that combines decision trees with deep reinforcement learning. Firstly, we establish the optimized scheduling framework based on fusing decision tree and reinforcement learning. Secondly, we construct a decision tree offline with training data generated by mathematical optimization methods. Then, we design a fusion model focusing on the dynamic regulation of action probability, and design a fusion algorithm and network. Simulation results show that the proposed algorithm can automatically adapt to uncertain environments and reduce energy costs of variable volume water heater by 23.2% compared to fixed volume water heaters, while satisfying user comfort requirements.","PeriodicalId":355442,"journal":{"name":"2023 2nd Asia Conference on Electrical, Power and Computer Engineering (EPCE)","volume":"89 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":"133868107","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 data flow of industrial Internet involves the interactive transmission of a large number of key sensitive information between enterprises. Coupled with its inherent openness and heterogeneity, it is facing serious security challenges such as sensitive data leakage and integrity destruction. Cryptography technology is one of the important methods to ensure data security. Among them, the national cryptographic algorithm can meet the requirements of security, autonomy and controllability of Chinese industrial Internet data, and avoid the risk of \"backdoor\" when the current mainstream international cryptography algorithm protects the key sensitive data. However, there are still security threats such as memory leakage and time-side channel attack which cause the invalidity of encryption mechanism when the national cryptographic algorithm is deployed in industrial Internet system. Formal verification method is an important method to verify the security and reliability of cryptographic algorithms. Existing researches have designed a variety of formal verification mechanisms for the underlying cryptographic algorithms of some structures and protocols, but the research on formal verification for national cryptographic algorithm is still in a blank stage. This paper proposes a formal verification method of SM4 cryptographic algorithm based on programming framework F*, which can ensure the memory security and resist the time-side channel attacks during the implementation of the algorithm. And the method can reduce the security risks, when the national cryptographic algorithm is deployed in the industrial internet.","PeriodicalId":355442,"journal":{"name":"2023 2nd Asia Conference on Electrical, Power and Computer Engineering (EPCE)","volume":"185 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":"133465610","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}

At the same time, speaker recognition is widely studied and used as a very valuable biometric recognition technology. However, the application of speech enhancement and speaker recognition technology in Tibetan is few. Due to the lack of speech enhancement back-end processing, the speaker recognition system may lead to low speech quality and low intelligibility. In this paper, the backend structure framework of SKA-TDNN network and Wave-U-Net model is constructed to realize noisy Tibetan speaker verification, and the model is improved and optimized. For speaker recognition, we use the model structure of SKA-TDNN in combination with multiscale SKA (msSKA) to better model utterances with different durations. In the back-end processing of speech enhancement, we use WAVE-U-NET structure and introduce further improved optimization architecture. Experimental results show that the improved SKA- TDNN model in speaker verification than traditional investigate VGG model was reduced by 5.225%, than ECAPA -TDNN model was reduced by 1.5%, and got close to 0.94 STOI in speech enhancement.","PeriodicalId":355442,"journal":{"name":"2023 2nd Asia Conference on Electrical, Power and Computer Engineering (EPCE)","volume":"4 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":"123850970","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}
