Problems solved by technology

[0006] In order to solve the existing technology, due to the different maintenance capabilities of vehicle owners, there are differences in the requirements for auxiliary means required for maintenance. However, in the prior art, there is a lack of such intelligent auxiliary tools for vehicle maintenance, resulting in the existing vehicle maintenance. The problem that is difficult to be carried out by the car owner himself, the present invention proposes a voice command recognition method for smart glasses applied in the field of car maintenance

Embodiment 1

[0052] Embodiment 1: A voice command recognition method for smart glasses applied in the field of automobile maintenance includes the following steps:

[0053] S1. The operator puts on smart glasses, switches the glasses mode to the operation mode, and conducts voice operation interaction;

[0054] S2. The microphone array of the smart glasses acquires and collects user voice commands;

[0055] S3. The voice command is transmitted to the voice recognition matching module in the smart glasses host, and the preprocessing of the voice and the feature extraction of the voice signal are performed. The extracted features are classified and recognized, and it is judged whether it is a voice command signal. If it is a voice command signal, Match with the instructions in the voice instruction library, and select the most similar instruction as the output;

[0056] S4. If the instruction is matched successfully, the control module receives the instruction input, performs the corresponding instr...

Embodiment 2

[0061] Embodiment 2: It has the same technical solution as embodiment 1, the difference is: a light source is installed in the accommodating part of the camera 15 and corresponds to the light source hole 8 on the second straight plate 14, the microphone 11 is installed inside the first straight plate 4, and the glasses The horn 12 is installed near the ear of the temple 1 when wearing smart glasses; the camera 15 is supported by the camera 15 bracket 9 and installed in the accommodating part of the camera 15, and the gyroscope is used for Identify the vibration signal and set different vibration signals to perform corresponding actions on the smart glasses that maintain the car. The light source, microphone, and speaker are multi-directional interactive means to realize the maintenance of smart glasses, and realize a omni-directional intelligent interaction to improve the intelligence of smart glasses.

Embodiment 3

[0062] Embodiment 3: It has the same technical solution as embodiment 2, except that the camera 15, light source, microphone 11, and speaker 12 are connected to the control board 10. The control board 10 has a wireless communication module for receiving the camera 15, the light source, The signal sent by the microphone 11 can perform data processing on the received signal, and the control board 10 is equipped with a wireless signal transceiver module, and uses the signal transceiver module to send and receive signals to a remote server. The wireless signals include Wifi, Bluetooth, GPS, FM. Because the smart glasses are directly connected to the control board, the control board then performs signal interaction with the remote server, and the control board can also perform data processing on the received signal, that is, some simple identification operations or other operations can be completely controlled by the control board. Identification or other processing, or pre-processi...

Abstract

The invention relates to a speech instruction recognition method for intelligent glasses applied to the field of car maintenance, belongs to the field of car maintenance, and aims to solve the technical problems of speech instruction recognition of the intelligent glasses applied to the field of car maintenance. According to the technical scheme, the method includes the steps that speech instructions are transmitted to a speech recognition matching module in the mainframe of the intelligent glasses for speech preprocessed and sound signal feature extraction; extracted features are recognized in a classified manner to judge whether the extracted features are speech instruction signals or not; and if the extracted features are speech instruction signals, the speech instruction signals are matched with instructions in a speech instruction library, and the most similar instruction is selected and output. The method has the effects that convenience for using the intelligent glasses for car maintenance is increased greatly.

Description

Technical field [0001] The invention belongs to the field of automobile maintenance, and in particular relates to a voice command recognition method in which smart glasses are applied to the field of automobile maintenance. Background technique [0002] Most domestic car owners still rely on 4s stores when their cars have problems or need maintenance. But 4S shops have two obvious drawbacks, which are expensive and time-consuming. [0003] When people choose second place and choose a large number of informal repair shops, although it is convenient and cheap, but thinking of entrusting their car to those who are not formally qualified is tantamount to entrusting the body to no one. Doctors who are qualified to practice medicine are a little daunted when sending their children to teachers who are not qualified to teach. [0004] There are also some car owners who have hands-on skills and are willing to do it themselves. Because they have not undergone professional learning, they will...
