Under the circumstances, developing a strawberry picking mechanism and its automation to replace manual work is an urgent problem waiting to be solved. In this study, based on 3D modelling, stress analyzing and motion simulation, an automatic picking and simple structure robot was innovatively designed. This paper mainly focuses on the part of two robotic arms. The single robotic arm consists of 5 rotational joints, 5 small motors at the joint, 4 Aluminium alloy skeletons and a pair of claws. The claw is made from light materials, and a pliant component is mounted to the surface. Through calculations of its motion simulation, it indicates that each part of the arm can run flexibly with bearing the requests of stress. Moreover, the claws can reduce damage to the fruit during picking by the soft structure. The results of dynamic simulation show that robotic arms can satisfy the requirements of automatic low-damage picking for strawberries in the greenhouse under the ridge.","PeriodicalId":285980,"journal":{"name":"2020 7th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127497663","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}

Once it breaks down, it will bring great harm to power grid. Especially when the internal turn-to-turn short-circuit fault occurs, the high temperature and arc caused by the short-circuit current will not only burn out the transformer winding insulation and iron core, but also cause the transformer insulating oil to be decomposed by heat and produce a large amount of gas, thus causing the deformation, damage and even explosion of the transformer shell. Therefore, once the transformer fails, it must be removed from the power system in time. At present, for power transformers, relay protection can be divided into electric protection and non-electric protection. Electrical relay protection mainly includes differential protection, current quick-break protection and zero-sequence current protection. Non-electric relay protection mainly includes heavy gas protection, light gas protection, pressure release protection and quick-acting oil pressure protection. This paper introduces the working principle of common non-electricity protection devices, and theoretically analyzes the cooperation between non-electricity protection devices. In view of gas relay, this paper introduces the requirements of relevant standards for gas relay, sums up the matters needing attention in field use of gas relay, and analyzes the factors affecting the performance of gas relay. The application status and characteristics of gas relay in Heilongjiang power grid are investigated, and the problems in management are pointed out. Using the calibration platform, through a large number of experiments, the influence of caliber and gas relay action on the performance parameters of gas relay is studied. And it is ensured that safe and reliable operation of the power transform of the power grid.","PeriodicalId":285980,"journal":{"name":"2020 7th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126083645","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, with the explosive growth of data, traditional clustering algorithm is more and more difficult to meet the needs of big data analysis. How to improve the traditional clustering algorithm and ensure the quality and efficiency of clustering under the background of big data has become an important research topic of artificial intelligence and big data processing. The density-based clustering algorithm can cluster arbitrarily shaped data sets in the case of unknown data distribution. DBSCAN is a classical density-based clustering algorithm, which is widely used for data clustering analysis due to its simple and efficient characteristics. The purpose of this paper is to study DBSCAN clustering algorithm based on density. This paper first introduces the concept of DBSCAN algorithm, and then carries out performance tests on DBSCAN algorithm in three different data sets. By analyzing the experimental results, it can be concluded that DBSCAN algorithm has higher homogeneity and diversity when it performs personalized clustering on data sets of non-uniform density with broad values and gradually sparse forwards. When the DBSCAN algorithm's neighborhood distance eps is 1000, 26 classes are generated after clustering.","PeriodicalId":285980,"journal":{"name":"2020 7th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126145200","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}
