Embodiment Construction

[0073] The present invention will be further described below in conjunction with the accompanying drawings.

[0074] Such as figure 1 As shown, a kind of general equipment failure detection maintenance method provided by the present invention comprises the following steps:

[0075] S101 Data modeling of equipment failure maintenance

[0076] The fault maintenance data of various equipment is abstracted into a "fault-repair tree" model, and the model is transformed into a database for storage. The model conforms to the basic definition of a tree (data structure), and consists of four types of nodes: "phenomenon" nodes, "operation" nodes, "cause and repair" nodes, and "theoretically impossible" nodes.

[0077] A tree (data structure) is defined as follows:

[0078] a. Each node has zero or more child nodes;

[0079] b. A node without a predecessor is called a root node;

[0080] c. Each non-root node has one and only one parent node;

[0081] d. The remaining data elements...

Abstract

The invention discloses a general fault detecting and maintenance method for equipment. The general fault detecting and maintenance method for the equipment comprises the following steps of carrying out modeling on maintenance knowledge of the equipment faults, automatically detecting and diagnosing the faults and carrying out auxiliary maintenance based on a model, simulating maintenance training based on the model, optimizing an experience knowledge model in real time in the maintenance training process, and synchronizing maintenance information and experience knowledge model information in the maintenance training process. Compared with an existing equipment maintenance method, the general fault detecting and maintenance method for the equipment enables the accumulation and the sharing of equipment maintenance experience knowledge and the automatic diagnosis of equipment faults to be achieved, and assistance can be provided for related maintenance strategies through the analysis and the exploitation of the maintenance record information. In addition, effective transmission of the experience of experts to primary maintainers is achieved through the step of simulation training. The general fault detecting and maintenance method for the equipment is especially suitable for chemical defense troops and other occasions where a large amount of complex equipment needs to be maintained frequently and where the turnover rate of maintenance personnel is high. Practice proves that the general fault detecting and maintenance method for the equipment can obvious improve equipment maintenance efficiency, promote maintenance levels and improve maintenance quality.

Description

technical field [0001] The invention relates to the fields of intelligent databases and expert systems, in particular to a general equipment failure detection and maintenance method. Background technique [0002] With the rapid development of the national economy and society, the level of equipment in various industries in our country has also been significantly improved. Under the background of equipment modernization and informatization, it is imperative to informatize the inspection and maintenance of these equipments. At present, most domestic industries mainly rely on human experience and equipment instructions for equipment maintenance. It is difficult to standardize and unify the maintenance process, it is difficult to effectively disseminate maintenance knowledge and experience, and the degree of sharing of information resources is not high. waste of resources, and the level of equipment information management has not yet reached the advanced level.
