Firstly, using high-precision 3D scanner, point clouds are acquired from quadric surface models. Secondly, triangulated irregular network models are generated from the point clouds by Delaunay algorithm. Thirdly, normal vectors of the nearest neighborhood planes of points in point clouds are acquired by the least square fitting algorithm. Finally, mapping relationship between the distributions of normal vectors and the types of quadric surface models is constructed. As a result, in real applications, if the distribution of normal vectors obtained for a certain scanned quadric surface model is consistent with the constructed mapping relationship, surface type of the model can be rapidly identified. The proposed method is validated by using an experiment.","PeriodicalId":393766,"journal":{"name":"2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115678495","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 phase sensitive detector is an effective tool for discriminating the amplitude and phase of each frequency component signal. It can be considered as the optimal linear filter in case of Gaussian-type noise. In real applications, however, the noise has also rather distinctive impulsive characteristics. It is a challenging task to remove the impulsive noise effectively in multi-frequency phase sensitive demodulation. In this paper, an approach for impulsive noise removal is presented in multi-frequency phase sensitive demodulation, which takes advantage of the periodicity of a multi-frequency signal and the significant properties of the median filter. The current work focuses on the use of two-dimensional (2D) median filter to handle the impulsive noise that existed in the measured signal, i.e. a 2D median filter is employed as the pre-stage signal conditioning module prior to the phase sensitive detector. The main advantages of the proposed method are that: 1) increasing the number of samples within the median filter window, which benefits the consecutive impulsive noise removal, and 2) no additional storage and computational resources are required for hardware system. Two classical methods are selected as comparisons in experiment. Numerical simulations and experimental results demonstrate that the proposed method can effectively eliminate the influence of impulsive noise on multi-frequency phase sensitive demodulation, and is able to achieve outstanding signal-to-noise ratio (SNR) performance.","PeriodicalId":393766,"journal":{"name":"2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125367477","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 novel method for rotational speed measurement using a low-cost camera and image processing techniques is presented in this paper. Firstly, sequential images are continuously processed using a similarity evaluation method to obtain the periodic similarity level of captured images. Subsequently, the rotational speed is determined from the periodicity of a restructured signal through Chirp-Z transform and parabolic interpolation based auto-correlation, respectively. The measurement principle and system design are presented. The advantages of the proposed measurement system include non-contact measurement, low cost, no markers required and high accuracy. Experimental investigations into the effects of the periodicity detection algorithm, frame rate and image resolution on the accuracy and reliability of the measurement system are conducted on a purpose-built test rig. Experimental results demonstrate that the system with the frame rate of 100 fps yields a measurement error within ±0.6% over a speed range from 100 to 3000 RPM (Revolutions Per Minute). More accurate and reliable speed measurements over a wider speed range are achievable with higher frame rates.","PeriodicalId":393766,"journal":{"name":"2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127802340","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}

Independent Component Analysis (ICA) is used over the Fourier-domain spectral signals obtained from the input and its autocorrelation function. A notable difference on the standard deviation over a region of interest in one output can be distinguished in the current signals obtained from damaged and healthy motors.

The two-phase flow process is complex, and the flow patterns are jointly determined by the phase fraction and the flow rate. The traditional way of studying the flow patterns uses a single sensor, generally sensing one point, to discover and identify the flow patterns. However, these methods lack a comprehensive description from both the phase distribution and flow velocity. Therefore, it is essential to fuse different detection mechanism sensors to investigate the flow patterns in a more comprehensive way. In this work, an electrical resistance tomography (ERT) sensor measures phase fraction and a continuous wave ultrasound Doppler (CWUD) sensor measures velocity of two-phase flow. For the measurement, data of ERT is treated as a multivariate time-series and a method of graph signal processing named Modular Dirichlet Energy (MDE) is adopted to extract features. The results show that the combination of these two sensors can distinguish horizontal gas-water flow well and lays the foundation for the identification of oil-gas-water three-phase flow.","PeriodicalId":393766,"journal":{"name":"2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124673980","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}

Subject to the measurement condition, the lift-off effect is unavoidable which will affect the strength and trend of MFL signal seriously. In order to weaken the lift-off effect, this paper proposed a lift-off revision method to revise the measured signal down to a considerable level. Firstly, two corresponding signals at different lift-offs are measured. Then the signals are revised by a lift-off revision formula which is deduced based on the trend and depth-combination property of MFL signal. To demonstrate the feasibility and accuracy of the proposed method, the lift-off is revised not only from the simulation signals, but also from the experimental data of an artificial corrosion defect. In both cases, the proposed method shows a good performance for the lift-off revision of MFL signal.","PeriodicalId":393766,"journal":{"name":"2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126121377","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 existing chipless RFID technology for identification purposes, radar cross-section (RCS) vs. frequency information is often used to create a unique identification (binary) code of 1's and 0's. In contrast, for purposes such as environmental sensing (i.e., temperature, humidity, gas concentration, etc.), a shift in the RCS frequency response is then correlated to the sought-for information. In this paper the utility of embedding chipless RFID sensors in various dielectric materials is investigated, where changes in the material properties cause a shift in the RFID frequency response and the changes are translated to a change in its original binary code. To illustrate the efficacy of this unique technique for materials characterization, electromagnetic simulations and measurements were conducted, the result of which are presented in this paper.","PeriodicalId":393766,"journal":{"name":"2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125963747","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 intended aim is achieved through the development of a monitoring system concept and its concrete implementation on a Festo Flexible Mechatronics System (MPS 202), a small-scale automated production line. The integration and connection of various sensors allow data collection and communication to a cloud infrastructure, where data are processed and analyzed. Data analytics can highlight key performance metrics that are visualized and streamed on a dashboard, facilitating the understanding of process conditions. The system generates alarms on mobile devices in case of anomalies in the Festo system, allowing users to immediately realize whether an undesired event is occurring in the system.
