While alarming , the configuration software informs the expert system to diagnose it through dbcom . while establishing the diesel engine fault diagnosis system , the systematic point of view is used in this paper to analyze and diagnose the fault of diesel engine , the 在诊断过程中,采用系统的观点对柴油发动机系统进行了故障机理分析和故障诊断,采用面向对象与产生式相结合的知识表示方法,构建了故障诊断专家系统的知识库和推理机制,通过自动获取和人机交互获取柴油机的实时状态信息,实现了对柴油发动机系统常见故障的诊断。
On the basis of developing unmanned automation monitoring system for a internal combustion engine unit , the diesel engine unit is chosen as a specific research object from the point of view of industrial application . the technologies , such as signal processing , wavelet analysis , rough sets theory and neural network , etc . , are used to monitor and diagnose this unit . the methods of diesel engine fault diagnosis and character abstraction are thoroughly researched 论文从工程应用的角度出发,在研制无人值守自动化内燃机组监控系统的基础之上,以内燃机发电机组为特定研究对象,利用信号处理、小波分析、粗糙集理论和神经网络等技术,对其进行状态监测以及故障诊断,并深入研究内燃机故障特征提取和诊断方法。
According to the current situation and developing trend of domestic and foreign diesel engine fault diagnosis , combined with the need of practical project , the diesel engine fault diagnosis based on crankshaft instantaneous angular acceleration is carried out ; principles and feasibility of this method are studied theoretically 经过了解国内外柴油机故障诊断的现状和发展趋势,结合实际项目的需要,提出了使用发动机曲轴角加速度信号来进行故障诊断。从理论上详细研究了这一柴油机故障诊断方法的原理和可行性,文中指出了这种方法的优缺点和适用范围。
For acquisition of rules , the characters of diesel engine faults are discussed in this paper . the system in a diesel engine is divided into several sub system according to its structure , and the probable faults of each sub system are discussed . those lead to the determination of diesel ' s fault modules 为了获取诊断知识规则,本文指出了内燃机故障诊断的性质和特点,并根据柴油机的结构,将柴油机按照子系统进行分层,分析了这些子系统可能出现的故障,确定了柴油机可能的故障模式。
Sixth , because internal combustion engine fault diagnosis is both crucial and difficult problem , and the current method only obtains part miscellaneous information , this paper deals with inspecting temperature , pressure , flow volume and thermal process , and realizes fault sampling . it enhances accuracy , reliability and practicability 本论文提出了采用对温度、压力以及流量等热工参数的监测,实现对故障的采样,因而在准确性、可靠性和实用性等方面都有较大的提高。
