[0005] However, the above method has the following problems: it is impossible to intelligently control the system in real time and the operation efficiency is low. Summary of the invention
[0006] To this end, the present invention provides a method and system for processing urban and rural planning data to overcome the problems in the prior art of being unable to intelligently control the system in real time and having low operating efficiency.
[0007] To achieve the above object, the present invention provides an urban and rural planning data processing system, wherein the system is provided with a plurality of noise monitoring devices arranged in groups along the traffic routes at the junction of urban and rural areas, and a single noise monitoring device comprises:

[0016] The vehicle noise is the noise generated in the air by vehicles along the traffic routes at the junction of urban and rural areas;
[0017] The resonance noise is the noise generated by vehicles on the ground along the traffic routes at the junction of urban and rural areas;
[0018] The pre-processed data is to fit the corresponding waveform according to the filtered data and generate a number of audio data with a sampling rate of a standard sampling rate, and the processing module generates a corresponding indicator feature according to each audio data;
[0019] The standard sampling rate is a sampling rate that can be recognized by the processing module, and for a single sampling, the corresponding standard sampling rate is a single sampling rate.
[0020] Furthermore, the receiving module includes:

[0031] Furthermore, the noise sensor groups located at the ground and underground positions respectively collect the vibration frequencies of the air and the ground of the traffic lines at the urban-rural junction, and convert them into the corresponding sound data through the converter. The collector receives the sound data, and a monitoring volume threshold is set in the filter. For a single sound data, when it reaches the monitoring volume threshold, the filter collects the sound data corresponding to the preset filtering time before reaching the monitoring volume threshold, and forms corresponding vehicle noise data and resonance noise data.
[0032] Furthermore, the preprocessor preprocesses the vehicle noise data and the resonance noise data to generate corresponding preprocessed data, and the preprocessing further includes:
[0033] Based on the data collection characteristics of the filtered data set, data cleaning is performed to obtain cleaned data of the filtered data set, and the cleaned data is standardized;

[0041] Furthermore, the degree of overlap between the vehicle noise distribution map and the resonance noise distribution map in the parallel propagation map is calculated, and an overlap threshold is provided in the adjustment module. When the overlap is less than the overlap threshold, the adjustment module does not make adjustments along the traffic route. When the overlap is greater than the overlap threshold, the adjustment module adjusts the monitoring volume threshold and the preset filtering time, and sets a sound insulation belt along the traffic route.

[0047] Furthermore, by providing a converter in the receiving module to convert the surrounding sound into vehicle noise and resonance noise, it is easier for the noise learning model to learn the noise data, thereby improving the efficiency of regulating the noise data.
[0048] Furthermore, by filtering the vehicle noise and resonance noise in the filtering module, the corresponding vehicle noise data and resonance noise data are obtained, thereby eliminating the error in the learning result caused by the error in filtering data processing during the learning process, and making the learning result more accurate.
[0049] Furthermore, by setting a monitoring volume threshold in the filter, noise screening is achieved, which facilitates real-time adjustment of noise and effectively improves the accuracy of noise recognition.

[0064] An adjustment module, which is connected to the filtering module and the processing module, is used to receive the noise distribution map, calculate the overlap of the sound data, and make adjustment measures for the noise source and the filtering module;
[0065] Among them, the sound data includes vehicle noise and resonance noise;
[0066] The filtered data is the corresponding vehicle noise data and resonance noise data generated after the sound data is filtered;
[0067] The noise learning model is trained and generated based on the filtered data set for the vehicle noise data and the resonance noise data;
[0068] The filtered data set includes vehicle noise data and resonance noise data at different periods of traffic routes at the urban-rural junction;
[0069] Vehicle noise is the noise generated in the air by vehicles along traffic routes at the junction of urban and rural areas;

[0072] The standard sampling rate is a sampling rate that can be recognized by the processing module, and for a single sampling, the corresponding standard sampling rate is a single sampling rate.
[0073] In a specific implementation, the indicator features of the preprocessed data can be selected as the decibel and generation location of the noise.
[0074] Preferably, setting the sampling rate to 7000 Hz has a better learning effect on the preprocessed data, and for the system described in this application, the corresponding analysis effect is optimal.
[0075] By providing a number of noise monitoring devices arranged in groups, including: a receiving module, used to collect sounds in traffic lines at urban and rural junctions, and generate corresponding sound data, a filtering module, used to filter the sound data, and generate a corresponding noise learning model, a processing module, used to pre-process the filtered data, select a number of indicator features to learn the pre-processed data, and generate a corresponding noise distribution map, an adjustment module, used to receive the noise distribution map, calculate the overlap of the sound data, and make adjustment measures for the noise source and the filtering module, while effectively improving the accuracy of noise identification, the accuracy of noise pollution position identification of traffic lines at urban and rural junctions is improved, and the noise of traffic lines at urban and rural junctions is visualized by using the learning model, thereby effectively improving the accuracy of noise pollution position identification of traffic lines at urban and rural junctions.
[0076] Specifically, the receiving module includes:
[0077] A noise sensor group is arranged at corresponding ground and underground locations to respectively collect the vibration frequencies of the air and the ground of the traffic routes at the junction of urban and rural areas;
[0078] The converter is connected to the noise sensor group and is used to convert the vibration frequency of the air and the ground into vehicle noise and resonance noise.
[0079] By setting a converter in the receiving module to convert the surrounding sound into vehicle noise and resonance noise, it is easier for the noise learning model to learn the noise data, thereby improving the efficiency of regulating the noise data.
[0080] See also Figure 2 As shown, it is a schematic diagram of the structure of the filtering module of the present invention, comprising:

[0084] By filtering the vehicle noise and resonance noise in the filtering module, the corresponding vehicle noise data and resonance noise data are obtained, which eliminates the errors in the learning results caused by the wrong processing of the filtering data during the learning process, making the learning results more accurate.
[0085] See also Figure 3 As shown, it is a structural schematic diagram of the processing module of the present invention, including:
[0086] A preprocessor, which is used to preprocess the vehicle noise data and the resonance noise data to generate corresponding preprocessed data;
[0087] a receiver, connected to the generator, for receiving the noise learning model;
[0088] The learner is connected to the receiver and the preprocessor, and is used to select several indicator features of the preprocessed data, learn the preprocessed data according to the noise learning model, and generate corresponding vehicle noise distribution maps and resonance noise distribution maps.
[0089] Specifically, the noise sensor groups located on the ground and underground respectively collect the vibration frequencies of the air and the ground of the traffic lines at the urban and rural junctions, and convert them into corresponding sound data through the converter. The collector receives the sound data, and a monitoring volume threshold is set in the filter. For a single sound data, when it reaches the monitoring volume threshold, the filter collects the sound data corresponding to the preset filtering time before reaching the monitoring volume threshold, and forms corresponding vehicle noise data and resonance noise data. Embodiment 1:
[0090] Assume that the monitoring volume threshold is 7000Hz. If the volume of sound data A is 6000Hz, the sound data A will not be collected. Embodiment 2:
[0091] Assume that the monitoring volume threshold is 7000Hz and the preset filtering time is 0.5s. If the volume of sound data B is 8000Hz, the filter collects the sound data corresponding to 0.5s before the sound data B reaches the monitoring volume threshold of 7000Hz and forms the corresponding filtered data.
[0092] By setting the monitoring volume threshold in the filter, noise screening is achieved, which facilitates real-time adjustment of noise and effectively improves the accuracy of noise identification.
[0093] Specifically, the preprocessor preprocesses the vehicle noise data and the resonance noise data to generate corresponding preprocessed data, and the preprocessing also includes:
[0094] Based on the data collection characteristics of the filtered data set, data cleaning is performed to obtain the cleaned data of the filtered data set, and the cleaned data is standardized;
[0095] Among them, data cleaning is to remove the corresponding data of the sound data below the monitoring volume threshold in the filtered data;
[0096] The normalization process is to divide the filtered data into segments according to the standard sampling rate.
[0097] By preprocessing the filtered data, the corresponding preprocessed data is obtained to improve the recognition efficiency of noise, so that the effective features of the preprocessed data can be quickly selected, thereby further improving the accuracy of identifying the location of noise pollution in traffic routes at urban and rural boundaries.
[0098] Specifically, the receiver receives the corresponding noise learning model, and the noise learning model learns the preprocessed data according to the indicator characteristics to generate the corresponding noise distribution map.
[0099] Among them, the indicator characteristics include the decibel level and generation location of the noise;
[0100] Learning is to convert the preprocessed data into a spectrogram, extract the index features in the spectrogram, and annotate the spectrogram based on the index features;
[0101] The noise distribution map includes the vehicle noise distribution map and the resonance noise distribution map.
[0102] Specifically, the adjustment module receives the noise distribution map, and calculates the time difference between the propagation of vehicle noise and resonance noise based on the difference in the propagation speed of sound in solid media and gaseous media, and translates the vehicle noise distribution map by the time difference in the noise distribution map to obtain the corresponding parallel propagation map. Embodiment 3:
[0103] The speed of sound propagation in solid media is 5200m / s, and the speed of sound propagation in gas media is 340m / s. Assuming that the noise propagates for 176800m, the time difference between the propagation of vehicle noise and resonance noise is 486s. In the noise distribution diagram, the vehicle noise distribution diagram is translated by 486 units to obtain the corresponding parallel propagation diagram.
[0104] Specifically, the degree of overlap between the vehicle noise distribution map and the resonance noise distribution map in the parallel propagation map is calculated. An overlap threshold is set in the adjustment module. When the overlap is less than the overlap threshold, the adjustment module does not make adjustments along the traffic route. When the overlap is greater than the overlap threshold, the adjustment module adjusts the monitoring volume threshold and the preset filtering time, and sets up sound insulation strips along the traffic route. Embodiment 4:
[0105] The overlap threshold is set to 80%. When the overlap between the vehicle noise distribution map and the resonance noise distribution map in the parallel propagation map is 70%, the adjustment module does not make any adjustments along the traffic route. Embodiment 5:
[0106] Set the overlap threshold to 80%, the monitoring volume threshold to 7000Hz, and the preset filtering time to 0.5s. When the overlap between the vehicle noise distribution map and the resonance noise distribution map in the parallel propagation diagram is 90%, the adjustment module will adjust the monitoring volume threshold to 6500Hz, the preset filtering time to 0.6s, and set up sound insulation strips along the traffic routes.
[0107] By setting the overlap threshold and adjusting the noise source and filtering module, the accuracy of identifying the location of noise pollution in traffic routes at urban and rural boundaries is improved, and the complexity of urban and rural planning data processing is reduced.
[0108] See also Figure 4 As shown, it is a flow chart of a method for processing urban and rural planning data of the present invention, comprising:
[0109] Step S1, the generator iteratively optimizes the noise learning model according to the filtered data set until the loss value converges to a preset value;
[0110] Step S2, testing the current noise learning model by filtering the data set;
[0111] Step S3: When the test result meets the preset test result, the noise learning model parameters are saved.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
