To ensure the safety of people entering the granary and improve the intelligent management of the access control, an intelligent access control system for granary based on face recognition and oxygen concentration is proposed in this paper. It uses sensors in multi-point to detect oxygen concentration in the granary in realtime, and jointly control the door lock with both oxygen concentration and face recognition. Users can view oxygen concentration data, personnel access situation, and remotely control the door lock through Web. This system realizes the intelligent construction and management of the granary, which not only reduces the management cost, but also guarantees the safety of people entering the granary. The design has passed actual tests to prove its effectiveness. It has good practical value and development prospect.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131444487","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}

Through it, the superior network management can obtain a large number of data such as configuration performance and operation and maintenance of optical network. For various reasons, there are usually missing values in real data sets. In order to improve the accuracy of filling missing values. In this paper, from the perspective of data mining, we use a variety of processing methods to fill the missing value of the north interface. In this paper, by analyzing the principle of KNN algorithm, decision tree algorithm, random forest algorithm and extreme random tree algorithm, the four algorithms are simulated in the missing value processing of northbound interface data respectively. The performance differences of various algorithms are compared and analyzed, and their advantages and disadvantages are compared. Finally, the most suitable algorithm for missing value processing of northbound interface data is found. Based on the simulation and experimental results, it is concluded that the extreme random tree algorithm has better filling effect in dealing with the missing values of the north interface.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134358895","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 accelerometer can measure gravity vector and help to determine pitch and roll angles, but its measurement is actually the sum of gravity and motion acceleration. As a result, the accuracy of pitch and roll angles will be affected under dynamic conditions. In this paper, optical flow sensor is used to measure the linear motion, and thus the motion acceleration can be estimated from optical flow data. Experimental results show that the proposed method can effectively eliminate the impact of motion acceleration and enhance the dynamic accuracy of AHRS.","PeriodicalId":403102,"journal":{"name":"2021 International Symposium on Computer Technology and Information Science (ISCTIS)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123858315","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 anti-UAV equipment on the domestic market has a single function and a small number, and it is easy to cause secondary damage after countering low-altitude UAVs.

This paper proposes a countermeasure against low-altitude UAVs based on software radio emitting pseudolite signals, which can guide low-altitude UAVs to a set direction, which can effectively counteract low-altitude UAVs.
