Aiming at the status that the water source well has large quantity, far distance, complex pipe network distribution, monitoring and leak detection and location is not timely, the water source well and pipe network monitoring system based on configuration software is designed. Working conditions of the water source well and the pipe network in mine can be monitored by using distributed substation acquisition and master station centralized monitoring. Field data collected from sub-station is transmitted to the master station through wireless data transceiver. The communication is realized between the master station and the remote monitoring center by using fiber Ethernet technology. The field data and alarm information can be real-time displayed and processed in the remote monitoring center by using KingView configuration software, which can realize manual and automatic control, local and remote monitoring. © Sila Science.

The rolling mill screw down AGC system sets several subsystems of machinery, electronics, hydraulics, controls in one. Under the action of responding extreme frequency or external disturbances, the non design objective coupling between the subsystems may be excited, and causing the most serious vibration, seriously impact product quality or even cause great destruction. Aiming at the defects in fault diagnosis and control system of the traditional rolling mill, the wireless remote monitoring system for the rolling mill AGC system vibration fault is designed in this paper. Using the advanced sensor technology, PLC and configuration software, GPRS network technology, the parallel distributed data acquisition and data processing for the key servo element and the hydraulic parameters which can characterize the fault characteristics of the system can be done. The monitoring software system platform on line of the hydraulic AGC system based on Kingview is set up for centralized real-time monitoring. According to the collected multidisciplinary parameter the fault identification and location is done by using the fault diagnosis expert system based on Web, thus to make the preliminary evaluation for the operation and fault of hydraulic AGC system and provide advanced prediction and exclude strategy. © 2013 Asian Network for Scientific Information.

Considering nonlinear behaviors and environmental disturbance of the boiler pressure control system, a linear interpolation fuzzy controller is developed. First, according to the conventional discrete fuzzy control principle, a discrete fuzzy controller for the system is designed and a 2-D fuzzy control lookup table is deduced. Then, to overcome the conventional fuzzy controller's disadvantage of lower precision caused by discretization, a bilinear interpolation 2-D table lookup method is used to replace the exact lookup method, with which continuous output can be obtained from the discrete control table. Finally, based on the existed computer control system and boiler system hardware configuration, hard-in-loop real-time simulation system is established in Matlab/RTWT. Lots of experiments are carried out. And the results prove that better control performance can be achieved with the proposed control scheme. © 2013 IFAC.

Parity space-based fault diagnosis of CCBII braking system

Journal of Central South University 2013年第10期20卷 2922-2928页

作者：黄志武杨迎泽王晶李赟 School of Information Science and Engineering Central South University Institute of Communication Control and Safe Operation for Transportation SystemCentral South University Hunan Engineering Laboratory for Advanced Control and Intelligent Automation School of Computer Engineering Bethune-Cookman University

Fault diagnosis is a key issue of the CCBII(computer controlled brake II) braking system, because the CCBII braking system is very complicated and nonlinear, which may exhibit isolated and multi-component coupled faults. A parity space-based method was proposed for fault diagnosis of CCBII braking systems. Firstly, the mathematical models were established according to three function modules of CCBII braking systems where the air fluid theory was utilized. Then, parity vector and threshold function were designed for each output of the system so as to identify more system faults. Fault character matrix was built based on the causal relationship between the output and the fault according to the system function and internal structure. Finally, fault detection and isolation can be realized by the comparison of the observed system output and the fault character matrix. Simulation results show that the proposed method is entirely feasible and effective.

Fano resonances in plasmonic nanostructures have asymmetric line shape and sharp resonance, and they are very attractive for biosensing applications. The implementations of biosensing rely on plasmon line shape engineering. In this work, we report that when the symmetry of a hexamer is lowered to D 2h point group, two B 3u and two B 2u dark subradiant modes are excited, and there are four kinds of Fano resonances. According to plasmon hybridization theory, the B 3u and two B 2u modes interact with plasmons of the central partical for heptamers with D 2h symmetry. We demonstrate that besides the influence on the resonance behavior, or the appearance of an additional Fano resonance for a certain polarization, there are several hybridized dark subradiant modes for both polarizations, and up to eight kinds of Fano resonances appear in the spectra. Plasmonic clusters with D 2h symmetry are very suitable for plasmon line shaping, and they would useful for multi-wavelength sensing applications. This work also reveals that cluster symmetry engineering is a good method to tune spectral features and to form multiple Fano resonances, and one can get similar results for plasmonic clusters with other symmetries.

In this paper, we investigate various surface structures of oxygen adsorption on Pd doping Zn-terminated ZnO (0001) by DFT. The results show that oxygen atom prefers to be adsorbed on the H sites of Pd substituting Zn atom of first Zn-O bilayers. The calculated PDOS indicates that a stronger interaction between adsorbed O2p and Pd4d orbitals has been happened at near the Fermi level. Finally, the bonding situation between adsorbed oxygen and surface is analyzed by electron density difference. The study reveals working mechanism of Pd-ZnO gas sensor, which is useful for finding the relationship between doping and sensitivity of sensor in experiment and theory.
