Interactive electronic technical manual-based online fault diagnosis equipment and online fault diagnosis method

Abstract

The invention discloses interactive electronic technical manual (IETM)-based online fault diagnosis equipment and an online fault diagnosis method. The equipment comprises five parts: an IETM content database, an IETM browser, an IETM fault diagnosis engine, an IETM log database and a test execution platform. According to the invention, an IETM is used as a core and a humanized interaction interface of the IETM is utilized to encapsulate a complicated fault diagnosis process, so that it is easy for a user to use and operate; the fault diagnosis engine and a test execution platform are integrated in the IETM, thereby substantially improving the fault diagnosis capability of the IETM; the equipment has a good modularity characteristic, so that it is easy to carry out updating and replacement of the fault diagnosis engine and the test execution platform; and the diagnosis method enables process information of the fault diagnosis and test data to be completely recorded, so that it is beneficial to analyze a fault cause after the fault occurrence. Moreover, the equipment with good portability can be applied to various equipment maintenance working sites; and the equipment enables maintenance personnel to be effectively guided to remove faults, thereby improving equipment maintenance working efficiency.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis of interactive electronic technical manuals, in particular to an on-line fault diagnosis device and method based on interactive electronic technical manuals. Background technique [0002] The technical manual is an important technical support for equipment maintenance support activities. With the increasing complexity of high-tech equipment, the number and complexity of technical manuals are also increasing. In the process of equipment repair, it is often impossible to quickly and accurately find the required technical information in the massive data. This affects the maintenance work. [0003] Interactive Electronic Technical Manual (hereinafter referred to as IETM) is the product of transforming and upgrading traditional technical manuals by using information technology. , in the form of text, images, audio, video, 3D animation, etc., to vividly and accurately display various technical...

AI Technical Summary

Problems solved by technology

[0005] At present, some companies have developed IETM and related products, but basically they all belong to the category of 1-4 IETM. Although these IETM products have certain fault diagnosis capabilities, they cannot be detected in real time due to the lack of effective online testing methods. Accurate fault detection and fault isolation for some complex fault modes are difficult due to perception and acquisition of technical status data of equipment
