近年来,随着超大规模集成电路、微型电子计算机、电一液控制技术的发展,光—机—电—液一体化技术在机械设备上的应用日益广泛.相应的状态监测和故障诊断任务日趋艰巨.此外,诊断技术和理论本身也有了长足的进步.可以说,上述情况从必要性和可行性两个方面推动了机械设备诊断技术的发展.下文仅就(1)监测系统的完善化;(2)自诊断系统;(3)监测诊断技术;(4)诊断工程新进展与新理论等四个方面介绍一些情况.一、监测系统的完善化机床加工刀具的在线监测和故障诊断系统在知识
In recent years, with the development of very large-scale integrated circuits, micro-computers and electric-liquid control technologies, the application of optical-computer-electric-liquid technology has become more and more widely used in machinery and equipment, and corresponding tasks of condition monitoring and fault diagnosis Arduous. In addition, the diagnosis technology and theory itself has also made great strides .This can be said that the above situation from the necessity and feasibility of promoting the development of mechanical equipment diagnostic technology.The following only on (1) monitoring system improvement; (2) self-diagnosis system; (3) monitoring and diagnosis technology; (4) new progress in diagnostic engineering and new theories, etc. Some of the situations are described as follows: I. Improvement of monitoring system Online monitoring and fault diagnosis system of machine tool know how
