Embodiment approach

[0043] As a specific implementation, the following methods can be used to establish an equipment fault library:

[0044] (1) Improve equipment information

[0045] 1) Establish equipment templates: Since the same type of equipment may be used in different factories and stations, in order to facilitate real-time monitoring and comparative analysis, the concept of equipment templates is introduced. The equipment of the same type imports relevant public information from the equipment template library and improves the personality configuration. The equipment template includes: equipment body information {template code: manufacturer information}, equipment measuring point {standard point name, actual measuring point name}, equipment parts {part code, number of failures}, equipment information, etc.;

[0046] 2) Establish a naming convention for equipment measuring points (equipment parameters), the structure of which is as follows:

[0047] P{stdName: standard roll call (business...

Abstract

The invention discloses an equipment fault diagnosis method and device. The equipment fault diagnosis method comprises the steps of: obtaining equipment parameters according to a preset parameter obtaining rule; obtaining a theoretical value interval of the equipment parameters according to a preset theoretical value model; comparing and analyzing the equipment parameters and the theoretical value interval thereof to obtain a comparison result; and performing equipment fault diagnosis according to the comparison result and an equipment fault library. By the adoption of the method, intelligent diagnosis of equipment faults is achieved, and the equipment fault diagnosis efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of equipment fault diagnosis, in particular to a diagnostic method and a diagnostic device for equipment faults. Background technique [0002] Equipment fault diagnosis is a technique to "see a doctor" for equipment. With the development of science and technology and production, the working intensity of equipment is increasing, the production efficiency and automation are getting higher and higher, and equipment diagnosis technology is playing an increasingly important role. It can make equipment trouble-free, work reliably, and maximize benefits. [0003] At present, the main diagnosis methods include: 1. Based on expert system, including: a. Intelligent expert diagnosis method based on shallow knowledge; b. Intelligent expert diagnosis method based on deep knowledge; c. Intelligent expert diagnosis method based on shallow knowledge and deep knowledge Expert mixed diagnosis method; 2. Based on artificial n...
