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. It is difficult for the car owner to solve the problem. This invention proposes a method for judging the abnormal noise of the car by smart glasses in the process of car maintenance.

Embodiment 1

[0050] Embodiment 1: A method for judging the abnormal sound of a car by smart glasses in the process of car maintenance, comprising the following steps:

[0051] S1. The operator switches the glasses mode to the recognition mode, issues voice commands and conducts sound fault analysis and recognition;

[0052] S2. The smart glasses microphone array acquires and collects sound signals;

[0053] S3. The sound signal is transmitted to the sound recognition and matching module in the host of the smart glasses to perform sound noise reduction, singularity detection, and feature extraction of the sound signal, classify and identify the extracted features, and determine the category of the sound and the degree of failure. At the same time, the analysis result information is transmitted to the control module;

[0054] S4. After the control module receives the result information, it controls the vibration feedback module to prompt the user, and controls the image output module to dis...

Embodiment 2

[0057] Embodiment 2: It has the same technical solution as Embodiment 1, the difference is: a light source is installed in the camera 15 accommodating portion and corresponds to the light source hole 8 on the second straight board 14, the microphone 11 is installed inside the first straight board 4, glasses Near the connection between the frame 2 and the convoluted bend; the speaker 12 is installed on the part of the temple 1 close to the ear when wearing smart glasses; the camera 15 is supported by the camera 15 bracket 9 and installed in the camera 15 accommodating part, and the gyroscope is used for Identify vibration signals and set different vibration signals to perform corresponding actions on smart glasses for car maintenance. Light sources, microphones, and speakers are multi-directional interactive means for maintenance using smart glasses, and realize a full range of intelligent interactions to improve the intelligence of smart glasses.

Embodiment 3

[0058] Embodiment 3: have the same technical scheme as Embodiment 2, the difference is: camera 15, light source, microphone 11 and loudspeaker 12 are connected to control panel 10, and this control panel 10 has wireless communication module, is used to receive camera 15, light source, The signal sent by the microphone 11 can be used for 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 the remote server. The wireless signal includes, Wifi, Bluetooth, GPS, FM. Since 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 recognition operations or other operations can be completely performed by the control board. Recognition or other processing, or pre-processing...

Abstract

The present invention provides a determination method of abnormal sound of a vehicle through adoption of smart glasses in the process of vehicle maintenance, belonging to the field of the vehicle maintenance. The technical problem that the smart glasses are configured to determine the abnormal sound of a vehicle in the process of the vehicle maintenance is solved. The technical scheme of the invention comprises: sound signals are transmitted to a sound recognition and matching module in the host of the smart glasses; noise reduction of sound, singularity detection and feature extraction of the sound signals are performed; the extracted features are classified and recognized; and the type of the sound and the fault degree is determined, and the analysis result information is transmitted to a control module. According to the invention, smart glasses have a recognition function of abnormal sound of a vehicle in the process of the vehicle maintenance.

Description

technical field [0001] The invention belongs to the field of automobile maintenance, and in particular relates to a method for judging abnormal noise of automobiles by smart glasses in the automobile maintenance process. Background technique [0002] When domestic car owners have problems or need maintenance, most of them still rely on 4s shops. But 4S stores have two obvious disadvantages, expensive and time-consuming. [0003] When people settle for the next best thing and choose the plethora of informal repair shops, although it is convenient and cheap, it is tantamount to entrusting their body to those without formal qualifications. When doctors with medical qualifications send their children to teachers without teaching qualifications, they are a little bit discouraged. [0004] There are also some hands-on skills, car owners who are willing to do it themselves, because they have not gone through professional learning, they will always feel a little unconfident when t...
