A study of information technology used in oil monitoring 总被引:8,自引:0,他引:8
Oil monitoring is referred to as wear particle debris analysis and physical analysis of lubricants' properties. Information technology, such as database technology, image processing, expert system, data fusion and multi-agent system theories, etc. makes oil-monitoring procedures more intelligent. This paper introduces the development of some information systems such as management database, computer-aided wear particle analysis software used in oil monitoring. The basic principles and models of information technologies used in this field are presented. The development of IT as an integral element of an oil analysis-based condition monitoring system has been carried out in the authors' laboratory since 1986. Initially, the principal application of IT was to improve the data management and processing procedures. The second use of IT was in the development of a wear particle image processing system. The third aspect of utilizing IT is artificial intelligence. Finally, the application of IT-based network techniques is implemented. The progress in the application of IT in the authors' laboratory shows that the combination of information technology and oil monitoring can increase the speed of oil analysis, manage the information conveniently and obtain analysis conclusion more precisely in relation to practical application. 相似文献

A real-time biological aerosol fluorescence detector was designed for monitoring aerosols in the atmosphere. The operating principles of the current biological aerosol monitoring system (BAMS) include the measurement of optically determined single particle properties, two fluorescence bands, and a scattering signal. Furthermore, the development of an algorithm to significantly increase the biological aerosol discrimination is described, which uses the results of the experimental evaluation of a number of aerosols in an evaluation chamber in the laboratory. The detector was applied to seasonal pollen, Asian dust, seawater environment, industrial zones, and residential areas in Korea. Applications of the device include all aspects of biological aerosol monitoring, including use as a biological agent trigger and as a hazardous environment monitor. The detectors were used in various laboratories as an ambient biological aerosol monitor and in various fields as a fast biological threat agent trigger in the 2010 G20 Seoul Summit and 2012 Nuclear Security Summit. 相似文献

Abstract The acoustic environment is an important variable in studies with animal behavior and psychology. Noise represents an important factor in laboratory settings. Noise of moderate intensity is produced by air conditioning devices and experimental equipment. Traditional automated video tracking systems require one personal computer per monitoring platform, which are noisy and inconvenient for large laboratory applications. This paper presents a stand-alone system for this function (noise-control environment/noiseless application). A novel system combination of FPGA and MCU simultaneously and automatically perform tracking and saving acquired data to an SD card. A fast and efficient tracking algorithm is designed and implemented. Detection via the designed algorithm uses the Y (luminance component), Cb (blue-difference chrominance component) and Cr (red-difference chrominance component) value of a colored marker affixed to the target to define the tracked position and allows multi-object tracking against complex backgrounds. The tracking result is updated every 30 frames/second and only the locomotive data are stored. The proposed system can track animal's locomotion totally noiseless operating. 相似文献
