In order to reduce the bit error rate of the shortwave wireless visible light communication system and increase the signal rate in the transmission process, the high efficiency and reliability of the modulation and demodulation technology must be realized. Therefore, the asymmetric limit orthogonal frequency division multiplexing technology (ACO-OFDM) is due to it’s excellent anti-interference ability and power efficiency are widely used in visible light communication systems. This article will introduce in detail the basic principles of ACO-OFDM technology, Hermitian mapping, and use BPSK, 4-PPM,16QAM for bit error rate simulation analysis, and select a modulation method rate with a lower bit error rate; analyze the linear block code, BCH The basic principles of coding and convolutional codes, and ACO-OFDM systems based on these three coding methods are simulated by Simulink, and their bit error rates are compared. Finally, ACO-OFDM based on convolutional codes was selected. This system is more suitable for visible light communication.","PeriodicalId":188256,"journal":{"name":"Proceedings of the 8th EAI International Conference on Green Energy and Networking, GreeNets 2021, June 6-7, 2021, Dalian, People’s Republic of China","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128660787","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}

Mobile phone film defect detection is a huge workload and challenging problem. Traditional methods can also detect some industrial identification defects, but these methods can only detect defects under specific conditions, such as obvious defect outline, strong contrast, low noise conditions. The defect detection method of mobile phone film proposed in this paper is to locate the target area with input images obtained from the industrial environment, remove the background, and then classify them into their designated classes through convolutional neural network. Experimental results show that this method can meet the robustness and accuracy of mobile phone film defect detection.","PeriodicalId":188256,"journal":{"name":"Proceedings of the 8th EAI International Conference on Green Energy and Networking, GreeNets 2021, June 6-7, 2021, Dalian, People’s Republic of China","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115712122","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}

Solar photovoltaic power generation is an important way to use solar energy. It can alleviate the existing energy crisis and various environmental problems caused by traditional energy. Photovoltaic power generation as a clean renewable energy gradually plays an increasingly prominent role in smart micro-grid. Due to the fluctuation of solar radiation intensity, accurate power prediction is one of the important conditions for the successful grid connection of solar power plants. This paper focuses on the prediction of ultraviolet power index. Based on the analysis of cumulative autoregressive moving average model, the stationary of ultraviolet index time series was detected, the order of ultraviolet index model was estimated, and the ARIMA model of ultraviolet index was determined. The prediction accuracy of the model is determined by the root mean square error (RMSE) and mean absolute error (MAE).","PeriodicalId":188256,"journal":{"name":"Proceedings of the 8th EAI International Conference on Green Energy and Networking, GreeNets 2021, June 6-7, 2021, Dalian, People’s Republic of China","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128122965","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}
