Detailed Description
The principles and features of the present invention are described below with reference to the drawings, the illustrated embodiments are provided for the purpose of illustrating the invention and are not to be construed as limiting the scope of the invention.
Referring to fig. 1 and 2, the present invention provides a vehicle running noise detection system for performing vehicle running noise detection, the system including a server and a vehicle-mounted terminal, the vehicle-mounted terminal being provided with a noise data acquisition module, a positioning module, an analysis module, and a policy module, the server being communicatively connected with the vehicle-mounted terminal module, the method including the steps of:
s1, a noise data acquisition module acquires noise data of a running automobile;
s2, when the noise data acquisition module acquires noise data of the running automobile, the positioning module positions the running automobile;
s3, analyzing the collected noise data and the automobile positioning data by an analysis module, and obtaining an analysis result;
and S4, the strategy module carries out strategy recommendation according to the noise analysis result.
For example, in order to reduce the influence of driving noise on a driver and improve the driving experience of the driver, the noise data acquisition module may be used to acquire noise data of a running automobile, during which the positioning module is used to position the running automobile when the noise is acquired, the acquired noise may be analyzed by the analysis module, and an analysis result is obtained, and then the strategy module performs strategy recommendation according to the analysis result, so as to improve the driving experience of the driver.
The noise detection module respectively performs noise collection on the inside and the outside of a running automobile through a first noise sensor and a second noise sensor arranged on the automobile, respectively obtains in-automobile noise and out-of-automobile noise data, and transmits the in-automobile noise and out-of-automobile noise data to the vehicle-mounted terminal.
For example, in order to reduce the influence of noise on a driver, the noise detection module may perform noise collection on the inside and the outside of the driving automobile through a first noise sensor and a second noise sensor disposed on the automobile, and the in-automobile noise and the out-of-automobile noise data are sent to the vehicle-mounted terminal, and the vehicle-mounted terminal performs the next process, so that different countermeasure strategies may be more advantageously adopted by distinguishing the in-automobile and out-of-automobile noise.
In step S2, when the noise data acquisition module performs noise data acquisition on the running automobile, the positioning module positions the running automobile specifically as follows:
and when the first noise sensor and the second noise sensor respectively collect noise from the inside and the outside of the running automobile, the positioning module acquires the running geographic position data of the automobile.
For example, in order to timely cope with noise conditions of different road sections, geographic position data of automobile driving can be obtained through a positioning module in the process of automobile driving, and a coping strategy can be adopted in advance when the automobile driving again to the road section at a time.
The step S3 further includes the sub-steps of:
s31, an analysis module sets a first noise threshold value and a second noise threshold value;
and S32, when the noise data in the vehicle is larger than a set first noise threshold value and the noise data outside the vehicle is larger than a set second noise threshold value, the analysis module analyzes the noise data in the vehicle, the noise data outside the vehicle and the geographic position of the vehicle, which respectively exceed the first noise threshold value and the second noise threshold value, and obtains a road section noise pollution analysis result.
By comparing the acquired noise data in the vehicle with the set first noise threshold value and the set second noise threshold value and analyzing the geographic position of the vehicle, a road section noise pollution analysis result is obtained, a corresponding strategy can be quickly adopted through the road section noise pollution analysis result, so that the influence of noise on a driver is reduced, and the specific analysis can be to process and analyze the acquired noise sound wave signals and to process the acquired sound wave signals, such as denoising, filtering and the like, by adopting a digital signal processing technology, so that the signal quality is improved; characteristic parameters such as frequency and amplitude in the sound wave signals are also taken, and the sound wave signals are classified and identified by the characteristic parameters so as to determine various sound sources in the running process of the vehicle, thereby judging whether the noise belongs to intermittent noise or persistent noise.
In step S4, the policy module performs policy recommendation according to the noise analysis result specifically as follows:
and the strategy module performs strategy recommendation of increasing the audio volume of the vehicle-mounted terminal or performing strategy recommendation of closing a vehicle window according to the road section noise pollution analysis result.
And the server sends noise early warning to other running vehicles close to road noise pollution according to the audio volume strategy recommendation of the vehicle-mounted terminal or the vehicle window closing strategy recommendation.
The server is in communication connection with the vehicle-mounted terminal, and the strategy module performs audio volume strategy recommendation of increasing the vehicle-mounted terminal or vehicle window closing strategy recommendation according to the road section noise pollution analysis result, namely, the strategy module can perform audio volume strategy recommendation of increasing the vehicle-mounted terminal or vehicle window closing strategy recommendation aiming at intermittent noise; the server sends noise early warning to other running vehicles with noise pollution close to road sections according to the audio volume strategy recommendation of the vehicle-mounted terminal, or the vehicle window strategy recommendation is closed, namely the vehicle window strategy recommendation can be closed to send noise early warning to other running vehicles with noise pollution close to road sections aiming at persistent noise.
