Civil aviation maintenance work card system based on voiceprint recognition and voice instruction control

Abstract

The invention provides a civil aviation maintenance work card system based on voiceprint recognition and voice instruction control, which comprises audio acquisition equipment, a noise reduction processing module, a voiceprint recognition module, a service processing module and a voice synthesis module, and is characterized in that the audio acquisition equipment acquires an audio file and transmits the audio file to the noise reduction processing module; wherein the noise reduction processing module performs environment sound filtering and human voice gain processing on a received audio fileand then transmits the audio file to the voiceprint recognition module, the voiceprint recognition module performs fragmentation, peak clipping and feature extraction on the audio file after noise reduction, constructs a voiceprint model according to features, compares the voiceprint model with a sample voiceprint model and returns comparison similarity, the models are transmitted to the service processing module, and the service processing module carries out identity verification according to the comparison similarity. According to the civil aviation maintenance work card system based on voiceprint recognition and voice instruction control, the safety problem of work card operation is solved through the biotechnology, and meanwhile the maintenance process is organized and intelligentizedbased on voice recognition control.

Description

technical field [0001] The invention relates to the technical field of civil aviation, in particular to a civil aviation maintenance worker card system based on voiceprint recognition and voice command control. Background technique [0002] With the development of aviation computer technology, communication technology and modern management, the entire production activities have entered the information age. The application of new technologies, new materials, and new processes, as well as the emergence of new systems, new designs, and new products, revolutionized the maintenance industry. The traditional maintenance work is carried out by maintenance personnel or engineers and inspectors holding paper work sheets on the aircraft site, recording the inspection results and checking the steps. The work is affected by many environmental factors. Now that the technology has improved, there are electronic workers. Card technology helps maintenance and inspectors to reduce some of t...

AI Technical Summary

Problems solved by technology

Among them, the signature module uses electronic signature technology, which has the following disadvantages: Although electronic signature technology is used, it is still based on handwritten input, which may be counterfeited, and it needs to connect to a third-party CA remote authentication service, which is expensive

The focus of this invention is electronic signature technology, focusing on safety, but it cannot improve the work efficiency and convenience of maintenance personnel

[0008] The electronic signature system has the following disadvantages: it only proposes to replace the paper work card with the electronic work card, and the electronic signature work card has not been further improved, and its function is single, and no further improvement is proposed for the digital work card. The reliability of the work order card cannot be guaranteed; the inspection and maintenance of civil aircraft is very important, so the work responsibility is assigned to the individual, the process protection and the uniqueness of the operator need to be strictly controlled. The electronic signature system cannot guarantee the work order. Card Accuracy and Authenticity

Although the electronic signature system has replaced some paper work sheets, it has not really liberated the hands of maintenance personnel and inspectors in their work, and there is still the inconvenience caused by paper work sheets. Aircraft inspection and maintenance have a need for work sheets. Authenticity, reliability, and preferably legal requirements are required to facilitate the implementation of responsibilities. In addition, it is especially important to clearly communicate the complicated procedures to maintenance engineers and inspectors during work, improve work efficiency, and reduce work errors. important
