Abstract

The invention belongs to the technical field of fault diagnosis of equipment, and relates to a voice interaction-based fault diagnosis method. The voice interaction-based fault diagnosis method is characterized in that four parts: a voice interaction module, an IETM (interactive electronic technical manual) browser, an IETM content database and a command mode database, are designed. The voice interaction-based fault diagnosis method has the beneficial effects that a complicated fault diagnosis process is packaged, so troubleshooting personnel is easy to use and operate the voice interaction-based fault diagnosis method; the fault diagnosis capability of IETM is improved; as the voice interaction module is designed in the system, the troubleshooting personnel can drive the IETM fault diagnosis strategy to be executed only by voice without operating the IETM browser, so that the troubleshooting efficiency is improved; a diagnosis result voice signal of the troubleshooting personnel is matched with a command mode, so that the recognition accuracy of a diagnosis result is improved, and the matching failure rate caused by the fact that the voice is noisy is reduced; the portability is good; voice interaction and interface display are synchronous, and can be used for equipment troubleshooting site work and the site appraisal of the troubleshooting personnel; the voice interaction-based fault diagnosis method is high in environmental suitability, and is not limited by light rays or work space.

Description

1. Technical field [0001] The invention relates to the technical field of fault diagnosis based on voice interaction, in particular to a fault diagnosis method based on voice interaction. 2. Background technology [0002] Fault is an unavoidable phenomenon for all equipment. Commonly used fault diagnosis methods include fault diagnosis based on experience and fault diagnosis based on technical data. The fault diagnosis method based on experience is the oldest diagnosis method. This kind of method has low cost, wide application range and rapid diagnosis, but it requires high experience of troubleshooting personnel, which is not conducive to the growth of young troubleshooting personnel. Fault diagnosis based on technical data is to use the technical data provided by the equipment manufacturer for fault diagnosis. This type of technical data can give a comprehensive overview of equipment failures and their causes. Even young troubleshooters can complete troubleshooting based o...
