Problems solved by technology

[0002] At present, most of the faults of hydraulic press equipment are based on the subjective judgment of the fault phenomenon. This method is easily limited by the subjective consciousness of the person and the technical personnel's own skills, and the troubleshooting is based on experience, not based on a certain order. Therefore, it is easy It causes a certain waste of time and energy, which leads to low efficiency in troubleshooting equipment fault components

Abstract

The invention discloses an equipment fault component troubleshooting method and system. The method comprises the following steps: obtaining component state abnormity data and equipment fault maintenance data; establishing a fault-component-sensor Bayesian belief network model; according to the fault-component-sensor Bayesian belief network model, calculating probability of actual abnormity of each component when each sensor connected with each component detects that the component is abnormal; ranking the probabilities from big to small in sequence to obtain ranked probabilities of actual abnormity of the components; and ranking the components according to the sequence of the probabilities of actual abnormity of the components, the component ranking the top being the component to be subjected to troubleshooting in priority. According to the method and system, the fault-component-sensor relationship can be established systematically, and the component which is most likely to fail when equipment fault occurs can be obtained quickly according to the relationship, thereby avoiding manual and subjective troubleshooting and improving equipment fault component troubleshooting efficiency.

Description

technical field [0001] The invention relates to the technical field of equipment maintenance, in particular to a method and system for troubleshooting equipment fault components. Background technique [0002] At present, most of the faults of hydraulic press equipment are based on the subjective judgment of the fault phenomenon. This method is easily limited by the subjective consciousness of the person and the technical personnel's own skills, and the troubleshooting is based on experience, not based on a certain order. Therefore, it is easy It causes a certain waste of time and energy, which leads to low efficiency in troubleshooting equipment fault components. Therefore, how to improve the troubleshooting efficiency of equipment fault components is an urgent problem to be solved in the technical field of equipment maintenance. Contents of the invention [0003] The purpose of the present invention is to provide a method and system for troubleshooting equipment fault co...
