IEEE Instrumentation and Measurement Technology Conference

作者： Zhiqiang Zhang Feng Dong Tianjin Key Laboratory of Process Measurement and Control School of Electrical Engineering and Automation Tianjin University TJU Tianjin China

A kind of measurement called “step” measurement method based on segmented capacitance electrodes is proposed in this paper. The “step” measurement method is implemented through increasing and reducing the width by increasingly involving more the capacitance electrodes towards different axis directions. By this kind of measurement, the information of the flow both locally and globally can be acquired. The capacitance electrode model and the measurement method are presented in details. Based the simulations using finite element method, the relative capacitance differences are calculated. The gas-liquid cross-sectional phase distribution (annular flow, stratified flow, bubble flow) are identified. Besides, the relation between the mean relative capacitance differences and the level of the water of stratified flow is nearly linear. The “step” measurement data contains a lot of information of the flow, and further work will focus on the feature extraction method of “step” measurement data.

Based on a higher raster angular displacement sensor, a fully-automatic higher precise apparatus for angular calibration is described. By using a higher resolution stepping motor, both of the two types of sensors, the standard raster sensor and the corrected sensor which are fixed in the same axial, can rotate coaxially at the same step. Meanwhile, the related software application platform is developed, which is being used for angular calibration and angular detecting. The output signals from the standard and corrected sensors can be transmitted to a host computer via one COM port. Take a kind of smart angular displacement sensor for calibration example, its angular displacement mathematic model embedded in MCU can be corrected by using this apparatus with higher accuracy so that the technique specification, like basic errors and linearity error can be improved greatly. For the four capacitive angular displacement sensors, their calibrating results sensors show that the averaged basic errors are 0.19%, 0.16%, 0.12% 0.15% respectively and the maximum is 0.62%, and the averaged linearity errors are 0.15% 0.12% 0.10% 0.14% respectively, and the maximum is 0.58% The accuracy of 1.0 level of this capacitive angular displacement sensor can be obtained.

Based on the analysis of signal of the piezoelectric detector, the relationship between natural frequency of the detector and vortex signal is discovered. Through the modal analysis of the piezoelectric detector's structure based on ANSYS, the relationship between the natural frequency and the detector's structure has been studied. Then by modifying the piezoelectric detector's structure and the low-pass filters' parameters, the measurement problem of high-frequency vortex signal has been solved.

IEEE Instrumentation and Measurement Technology Conference

作者： Cong Xu Feng Dong Tianjin Key Laboratory of Process Measurement and Control School of Electrical Engineering and Automation Tianjin University TJU Tianjin China

As a non-radiant and unperturbed 2D/3D boundary technique, Electrical resistance tomography (ERT) provides an effective way of monitoring and on-line measurements for multiphase fluid. To better satisfy industrial requirements, a parallel ERT system based on CompactPCI is described in this paper. The performance of this system have been tested, and the results show that the system works properly with SNR above 62dB with perfect repeatability less than 0.7%, and the data acquisition rate could reach almost 1400 frames per second under 50 kHz excitation. Static experiments have been conducted for image reconstruction and the images demonstrated good resolution relative to the actual object distribution. The parallel ERT system has provided a firm foundation for the dynamic multiphase flow measurements.

Component concentration of sodium aluminate solution is an important quality index for alumina production. In this article, we propose a new on-line soft sensing strategy for measuring component concentration of sodium aluminate solution. With this method, on-line control can be realised in aluminate production plants. Several advance techniques are used, such as principal component analysis (PCA), neural modelling and the least square algorithm. Industry experiments are conducted in the alumina production process and the results show the effectiveness of this method. © 2011 Taylor & Francis.

The real highway traffic flows are time series sampled from typical complex systems. Combination of forecasts is necessary for the accurate, fast and reliable forecasts of them. The real traffic flows are complex stochastic processes, with time-varying probability distribution functions, and many outliers. The last two factors reduce the authenticity of point estimations of variances and correlation coefficients from the forecasting error series of the all individual methods, and directly reduce the accuracy of theoretical best combination weights. Using estimators to the complex time series by robust statistics, can improve the authenticity of point estimations of variances and correlation coefficients, then can improve the combination of forecasts accuracy of short-term highway traffic flows. Numerical test results show the improvements. © 2011 IEEE.

In steelmaking and continuous casting (SMCC) production process, converter fault can lead to unexpected changes to the pre-specified converter-continuous caster production mode so that the original scheduling plan becomes unrealizable. In this paper, the dynamic scheduling problem in response to converter fault is firstly analyzed. This is then followed by the establishment of a novel multi-objective nonlinear programming model (MONPM) by introducing the production mode parameter α, production schedule parameter β and χ. The proposed method considers changes in production mode, production schedule of charge, the interval characteristics of processing time. In specific, a two-stage dynamic optimal scheduling method is proposed including the production path planning of charges (PPP) and the production time scheduling (PTS). As a result, a dynamic optimal scheduling software system (DOSSS) is developed and is successfully applied to the scheduling of the largest iron and steel company (BaoSteel) in China. The real-time application shows that the proposed method can efficiently reduce scheduling time, significantly increase the outputs of converters and dramatically shorten the redundant waiting time for molten steel. © 2011 IFAC.

Radial basis function (RBF) network is one of the significant neural networks. It has been used successfully in various fields. But in RBF network approximation algorithm, the initial value of the network weights, Gauss function center vector and broad-based vector is not easy to determine, and when these parameter choice is undeserved, RBF network approximation precision will decline and even the serious consequences of network spread will be produced. By using genetic algorithm in this paper, which can better realize RBF network parameter optimization, thereby increasing the accuracy of approximation. Scilab is open source software and has good simulation capabilities. Experiments using Scilab shows that the optimization method of genetic neural network is feasible and results are satisfied. © 2011 IEEE.
