Method Based on Knowledge Modules of Hydraulic Fault and it’s Application

Article Preview

Abstract:

According to various problems by using traditional redundant fault-tolerance technology and information fault-tolerant technology, a novel method of knowledge modules of hydraulic fault (KMHF) was proposed in this paper. The principle of the method was that new type of fluid information expression units were designed to perceive and process the fault information of the system, then the information was expressed as mechanical signal, hydraulic signal or electrical signal, which could be used to implement fault tolerance at power stage. The engineering application of the method of KMHF can solve the problems of the whole fault tolerance in the hydraulic system, moreover, with it the structure of hydraulic system can be greatly simplified.
