Generally, large vessels have to be used in these flux monitoring tasks with buoys. This paper describes a small buoy which is supported by national ocean technology center for flux measurement in air-sea boundary layer, capable of rapidly deployment and accurately measuring atmospheric and sea surface variables. It can be easily dissembled, carried, deployed and acquire meteorological and hydrological data, such as pressure, temperature and wind speed. The algorithm, which is based on the Monin-Obukhov similarity theory, the structure, which has an anti-rotation character, sensors installed on the buoy which have high accuracy and good stability and the process of the buoy control system are introduced in details. The buoy has been deployed in a sea area as a field test, and has a promising result. Compared to the traditional flux buoy, the small flux buoy is not only small and light in weight, and also can be used for flexible, low-cost and effective flux measurement. Besides, its low cost makes measurement in wide range possible. The buoy provides a new solution for air-sea flux monitoring and data source for flux model algorithm research.","PeriodicalId":275568,"journal":{"name":"2017 13th IEEE International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"63 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129576171","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 national development and reform commission and the national energy administration proposed to strengthen the capacity building of peak load regulation and improve system flexibility. In response to the national policy, a power generation group proposed a new requirement for thermal power flexibility. It puts forward higher requirements for the range of the unit's wide load and the variable load rate. The main evaluation methods of analog signals are the mean variance method and minimum variance method. Pearson correlation coefficient method is a way to evaluate the correlation between two variables in the field of statistics. By studying the Pearson correlation coefficient method in the field of statistics, it is applied to evaluate the analog signals in the process of peak load regulation as a new evaluation method. By extracting simulation machine operation data and analyzing the curve characteristics, the evaluation results of curves were obtained, and validated the feasibility and effectiveness of the Pearson correlation coefficient method in evaluating the analog signals in the process of deep peak-regulating.","PeriodicalId":275568,"journal":{"name":"2017 13th IEEE International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123833762","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}

A vibration measurement model with double magnetic suspension vibrators was designed. The function of magnetic repulsion and displacement of the vibrator was obtained by means of the measured and least squares function fitting method. The vibration equations of the two magnetic suspension vibrators were deduced respectively. A simulation model of vibration measurement system with double magnetic suspension vibrators was established. The simulation shows that the sensitivity of the double magnetic suspension vibrators is higher than that of the single magnetic suspension vibrator. When these large infrastructure equipment work, the vibrations of the building were measured. The data components of the vibration signals were analyzed by wavelet decomposition method. Finally, the free vibration waveform of the buildings, the vibration waveform of the building generated by excavators and forklifts were reconstructed. The experimental results show that the magnetic levitation measurement method is suitable for low frequency vibration measurement and its measurement sensitivity is higher. The method can be used to assess the level of vibration generated by large infrastructure equipments.","PeriodicalId":275568,"journal":{"name":"2017 13th IEEE International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116471882","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}
