大型移动多机电设备在线状态监控系统研究

Online Condition Monitoring System for Large-scale Mobile Multi-electromechanical Equipment

对大型移动多机电设备进行全面的实时在线状态监控,是目前国内外尚未完全解决的课题。依据设备端检测装置功能的不同,建立了一种大型移动多机电设备在线状态监控系统的分类标准,界定了检测装置的黑匣子功能模型和白匣子功能模型,提出了灰匣子功能模型,并对基于三种功能模型的状态监控系统结构进行了简要描述。对黑匣子系统的特性进行了深入分析,指出了其适用范围和局限性;指出了白匣子系统存在的技术瓶颈、局限性,及其该系统的理论意义;分别从硬件和软件角度说明了灰匣子系统的可实现性。通过算例分析,论证了灰匣子系统的优越性。为实际大型移动多机电设备在线状态监控系统的开发提供了理论依据,灰匣子系统还为未来大型移动智能设备的设计制造提供了有益参考。

The overall and real-time online condition monitoring for mobile large-scale multi-electromechanical equipment is a problem that has not been resolved totally.According to the different functions of the detecting devices on equipment,a classifying criterion of the online condition monitoring system for large-scale mobile multi-electromechanical equipment was set up.The black-box function model and the white-box function model of detecting devices were defined,and the grey-box function model was proposed.The structure of condition monitoring system based on the each function model was described briefly.The characteristics of black-box system were analyzed deeply,and its application scope and limitation was pointed out.The technological bottleneck,the limitation and the theory meaning of white-box system were indicated.The realization of grey-box structure system was explained in terms of hardware and software separately.Its superiority was demonstrated through an example.The theoretical foundation for the development of practical online condition monitoring system for mobile largescale multi-electromechanical equipment is offered.The grey-box system offers beneficial conferences for the design and manufacture of intended large-scale mobile and intellectual equipment.
