The algorithm divides the sampling into four different states. The frequency, amplitude, and phase of the dual frequency signals are calculated by analyzing the relationships between the real part and imaginary part of the spectral peak and sub spectral peak in the discrete spectrum of the signal in each state. There is not error nearly introduced by the algorithm whether the sampling process is in integer period. Therefore, no strict requirement is needed whether the data acquisition system realizes the integer period sampling and no need to use compensation algorithm to improve the accuracy. The simulation results show that the accuracy of the frequency, amplitude, and phase calculated in the algorithm reaches the level of 10−9. The correctness of the algorithm is verified, accuracy meets the calibrating requirements of harmonic and inter-harmonic parameters of power sources, power analyzers and other equipment. At present, the calibration program based on the algorithm has been applied to the calibration of harmonic and inter-harmonic parameters of relevant instruments, and good results have been obtained.","PeriodicalId":289132,"journal":{"name":"2021 IEEE 15th International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"212 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123499394","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 reduce noise interference and improve the detection accuracy of GMI magnetic signals, this paper proposes a current signal noise reduction method combining Least Mean Square(LMS) adaptive time delay estimation and DQLIA. LMS adaptive time delay estimation is added to DQLIA, using the noise reduction characteristics of LMS adaptive time delay estimation, makes the noise superimposed on the frequency-locked signal further reduced. Improve the detection accuracy of the GMI current signal and reduce the output fluctuation rate. Through MATLAB/Simulink simulation, the results show that under the condition of input signal-to-noise ratio(SNR) of −7.01dB, the output volatility of the improved method proposed in this paper is reduced by 15.6% compared with the traditional method. Therefore, simulations and experiments have verified the rationality and effectiveness of the proposed method.","PeriodicalId":289132,"journal":{"name":"2021 IEEE 15th International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132847582","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 algorithm first searches for the optimal segmentation threshold of the brightness channel of the input image through genetic algorithm. Then, according to the obtained threshold, the brightness channel is divided into multiple subgraphs with different exposure levels. Next, all subgraphs are assessed by the multi-threshold block enhancement method, and the brightness of each subgraph is adjusted according to the assessment. After that the multi-scale fusion method is used to fuse the details of the input image into the brightness-enhanced image. Finally, the output image with normal brightness and rich details is reconstructed. This paper selects the enhancement algorithm proposed in the past three years for comparison experiments. The results show that the low-illuminance image is enhanced by the algorithm in this paper. Its entropy increases by 66.2%, enhancement by entropy increases by 94.7%, and average gradient increases by 97.2%. The increase of each index of the image enhanced by the algorithm in this paper is greater than that of other comparison methods, which proves that the algorithm in this paper has better performance.","PeriodicalId":289132,"journal":{"name":"2021 IEEE 15th International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115823631","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}
