First, on a 50m high-precision guide rail, three sets of plane mirrors are used to achieve a fourfold optical path multiplication, so a 200m indoor baseline is established. Second, a theoretical model for error analysis is built, and then main sources of measurement error are determined. Next, under different situations, the effects of each error angle on both the deviation of the light spot on each component in the baseline system and the baseline length are analyzed.","PeriodicalId":337028,"journal":{"name":"The 8th International Symposium on Test Automation & Instrumentation (ISTAI 2020)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128865466","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 current smart campus service technology can no longer meet the requirements of data collection, governance and decision-making assistance. This paper proposes a method to create a multi-dimensional campus intelligent perception platform to collect huge multi-domain, multi-dimensional, and heterogeneous student data, and to use cross-domain big data fusion technology to establish a student growth smart service platform. This method designs a smart service system for the growth of middle school students. The system has the functions of integrating information resources, pushing targeted and customized talent development suggestions, as well as warning and intervention for related problems. These results can be more objective, comprehensive and efficient evaluation of students' comprehensive quality, push personalized education, and promote the healthy growth of middle school students.","PeriodicalId":337028,"journal":{"name":"The 8th International Symposium on Test Automation & Instrumentation (ISTAI 2020)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130788099","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}

Aiming at the limitation of timing error detection and long timing time in the closed-loop Gardner timing recovery algorithm, the timing error detection method is modified, and an improved method of adding gain control processing is proposed. The simulation results show that the improved algorithm can capture timing error of multi-level modulation signal, significantly reduce timing errors and shorten timing time. The steady-state timing jitter is an order of magnitude smaller than the classic loop. The timing recovery of MQAM signal and MPSK signal can be completed well, which proves the good applicability of the improved algorithm.","PeriodicalId":337028,"journal":{"name":"The 8th International Symposium on Test Automation & Instrumentation (ISTAI 2020)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133371647","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 improve the safety of the operation in the middle and later life of the nuclear power plant, the main factors affecting the operation safety in the middle and later life of the nuclear power plant are analyzed and studied. On this basis, the systematic scheme and measures to ensure the safe operation of the nuclear power plant are put forward. The program includes laws and standards, equipment performance monitoring and management, equipment aging management, equipment maintenance management, equipment life management, plant operation management, fault handling plan management, human factors management, regular safety inspection and nuclear safety supervision and management, etc. This study provides guidance for the supervision and management of the operation safety in the middle and late life of nuclear power plant, and provides a foundation for further in-depth study of the operation safety in the middle and late life of nuclear power plant.","PeriodicalId":337028,"journal":{"name":"The 8th International Symposium on Test Automation & Instrumentation (ISTAI 2020)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127108413","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 throat diameter of the nozzle is the main data of nozzle manufacturing and calculation. Accurate measurement of nozzle throat diameter plays an important role in how to save energy and reduce emissions, and accurately analyse energy loss. The roundness of nozzle throat is the main factor affecting the accuracy of diameter measurement. The roundness is measured and analysed accurately in the test. The diameter value is affected by roundness, which affects the accurate measurement of flow.","PeriodicalId":337028,"journal":{"name":"The 8th International Symposium on Test Automation & Instrumentation (ISTAI 2020)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115158558","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}
