[0002] The statements in this part merely provide background technical information related to the present disclosure and do not necessarily constitute prior art.

[0003] Subgrade diseases, such as settlement, cracks, deformation, and soil erosion, directly affect the structural stability and bearing capacity of roads, and may lead to potential vehicle driving safety hazards and traffic jams. With the changes in vehicle loads and environmental factors, these diseases will accelerate the damage of the road surface, reduce the service life of the road, increase the maintenance cost, and even threaten driving safety.

[0025] Compared with the prior art, the beneficial effects of the present disclosure are:

First, the model can not only accurately predict the elevation change of the road through training and learning of experimental data, but also deeply analyze the response of high-frequency road ends and low-frequency road ends during vehicle driving, so as to comprehensively evaluate the health of the road. This intelligent data analysis capability improves the accuracy and efficiency of monitoring and greatly reduces the cost and workload of manual detection. In terms of model structure, GOOSE-LSTM combines the time series prediction capability and adaptive weight adjustment mechanism of the long short-term memory network (LSTM), which can effectively mine complex patterns and long-term dependencies in the data. This enables the model to converge quickly and produce high-quality prediction results after inputting dynamic vehicle vibration data and position data. In addition, the output of this method can not only provide a quantitative assessment of road health, but also identify potential disease types and locations, provide important references for maintenance decisions of relevant departments, and ultimately realize intelligent and precise road management.

[0035] Example 1

[0036] In an embodiment of the present disclosure, a road health monitoring method based on data frequency self-matching is provided, including:

[0037] Step 1: Obtain the vehicle body vibration information and vehicle position information of the vehicle;

[0038] Step 2: Perform frequency self-matching on the output frequencies of the vehicle body vibration information and the vehicle position information, and extract the vibration information and position information within the same time period after frequency self-matching;

[0039] Step 3: Input the vibration information and position information within the same time period into the prediction model respectively, introduce a feature selection method for feature processing, and predict the road elevation data and subgrade disease data;

[0040] Step 4: Construct a road health status model, and connect the road information with the real-time map in the road health status model;

[0041] Step 5: Introduce a timestamp into the road health status model. After inputting the predicted road elevation data and subgrade disease data into the road health status model, assign time tags to them and compare them with the road elevation data and path disease data in the initial data set in the road health status model to identify abnormal points of elevation change and obtain potential subgrade disease risks.

[0042] As an embodiment, the road health monitoring method based on data frequency self-matching of the present disclosure is specifically implemented as follows:

[0043] Step 1: Obtain the vehicle body vibration information and vehicle position information of the vehicle;

[0044] Specifically, install vehicle body vibration displacement sensors on the four tire bearings of the vehicle, and use the Beidou system to locate vehicle information, specifically:

[0045] S1: Install the vehicle body vibration displacement sensors on the four tire bearings of the vehicle so that it can collect the vehicle's vibration data (vibration amplitude, vibration magnitude) and steering (turning) data;

[0046] S2: Set the data output system of the Beidou system, and output the vehicle's position data (position, orientation) and trajectory data after locating the vehicle.

[0047] Step 2: Perform frequency self-matching on the output frequencies of the vehicle body vibration information and the vehicle position information, and extract the vibration information and position information within the same time period after frequency self-matching;

[0048] Specifically, design the frequencies of the vehicle body vibration displacement sensor and the Beidou system data output. The data output frequency of the vehicle body vibration displacement sensor is designed to be 5 Hz, and the data output frequency of the Beidou system is 1 Hz, so that they can complete data coincidence and achieve data alignment through frequency self-matching.

[0049] Among them, as Figure 2 shown, the specific process of frequency self-matching is as follows:

[0050]

[0051] Among them, n m-1 represents the normalized frequency data, m represents the currently input candidate state, T1 represents the data collected by the vehicle body vibration displacement sensor, and T2 represents the data collected by the Beidou system.

[0052] After frequency self-matching, the data at the same time point is output, and the data is output according to the frequency of the data group with the lower acquisition frequency. As Figure 2 shown, the acquisition frequencies are 1 Hz and 5 Hz respectively, that is, the data volume of the Beidou system is equivalent to five times the data volume of the vehicle body vibration displacement sensor, which is convenient for the next step of data processing.

[0053] Step 3: Input the vibration information and position information within the same time period into the prediction model respectively, introduce a feature selection method for feature processing, and predict the road elevation data and subgrade disease data;

[0054] Specifically, first, the prediction model adopts a GOOSE-LSTM neural network structure, and the construction method of the prediction model with the GOOSE-LSTM neural network structure is as follows:

[0055] S1: Preprocess the GOOSE message data, extract key information such as timestamps, state changes, event types, etc., and organize them into a time series format. The goal of this processing is to make the data adaptable to the subsequent LSTM model and be able to capture time-dependent relationships and temporal features;

[0056] S2: Design the network structure of the LSTM, determine the number of nodes in the input layer, which usually corresponds to the number of features of the input time series. Design the LSTM hidden layer, which may include one or more LSTM layers, and each layer can set different numbers of units (nodes) to capture different levels of time features;

[0057] In the network structure of the LSTM, first, the input layer contains 10 nodes, corresponding to 10 features respectively (such as the vibration data and position information of the vehicle), which are used to receive time series data. Next, the first hidden layer is set to 64 LSTM units, mainly extracting the short-term time features of the data and capturing instantaneous changes. The second hidden layer is set to 32 LSTM units, further processing the output of the first layer and focusing on more complex time relationships and long-term dependence features. Then there is a fully connected layer with 3 nodes, which is used to map the extracted features to the final output. Finally, the output layer is also set to 3 nodes, outputting the predicted road elevation, road health, and potential disease types.

[0058] S3: Select a suitable training set for model training to ensure that the training set data is representative. Then, set the loss function. Mean Squared Error (MSE) is usually a common choice, which is used to evaluate the difference between the predicted value and the actual value of the model under specific inputs. After training is completed, use the validation set to evaluate the model effect and adjust the parameters;

[0059] S4: Analyze the number of nodes and layers of the selected input layer, hidden layer, and output layer, and test different network structures through cross-validation or grid search to find the best combination of nodes and layers;

[0060] S5: Determine the time window of the input data (vibration data, steering data, trajectory data, and position data), and analyze how these inputs affect the output. Determine the output data (road elevation, potential disease types, etc.). Introduce a feature selection method. Through the Lasso regression method, after model training, the algorithm will generate feature importance scores. By analyzing these scores, select the features that contribute the most to the prediction results, remove redundant and unnecessary features, and improve the performance and efficiency of the model.

[0061] Furthermore, input the vibration information and position information into the prediction model respectively, introduce a feature selection method for feature processing, and predict the road elevation data and subgrade disease data;

[0062] Among them, the road elevation data is predicted through the vibration data at the vibration end. The elevation change trend of the subsequent elevation is predicted based on the historical data elevation. Based on the vehicle flow trajectory data, such as speed and turning, when the vehicle encounters a diseased road end, such as a pothole, it will detour, and when it encounters a high elevation end, it will decelerate. Then, based on these features, the disease location is predicted.

[0063] Step 4: Build a road health status model, connect the road information with the real-time map in the road health status model, and introduce timestamps in the road health status model. Specifically, it includes:

[0064] S1: Input relevant map road information in the interface of the control platform of the road health status model, including the location, name, category, grade, start and end points, important traffic nodes, etc. of the road. Combine with the high-precision geographical location information provided by the Beidou system to establish a connection between the input road information and the real-time map data of the Beidou system;

[0065] S2: Establish a timestamp system, which will assign time tags to all input data for data synchronization and collation. When road data (vehicle position, vibration data, road elevation and trajectory data) is input into the system, each record should be appended with an accurate timestamp. These timestamps help us align the data from different data sources in time to ensure that all data information can be compared within the same time frame;

[0066] S3: Input certain basic parameters when collecting road-related data. These parameters include the width of the road, engineering grade (such as first-class highway, second-class highway, etc.), original elevation (initial height of the road surface), etc. Combine these parameters with the timestamp data to form an initial dataset for describing the basic characteristics of the road in a healthy service state. Collect the current road condition data through sensors or inspection records to establish a preliminary road health status model;

[0067] S4: Identify the trend of road elevation change by analyzing and comparing the collected data. Adopt deep learning methods, combine parameters such as road width and engineering grade, and identify the occurrence probability and development trend of different types of road diseases (such as cracks, potholes, etc.) through existing deep learning-based prediction models. Improve the prediction accuracy by comparing different categories of data groups, and thus provide a scientific basis for road maintenance and management.

[0068] Step 5: After inputting the predicted road elevation data and subgrade disease data into the road health status model, assign time tags and then compare them with the road elevation data and path disease data in the initial dataset in the road health status model to identify abnormal points of elevation change and obtain potential subgrade disease risks.

[0069] S1: Obtain the vibration information generated by the vehicle body vibration displacement sensor. This vibration displacement sensor predicts the elevation data related to the road surface by monitoring the vibration generated during vehicle driving. By performing spatial interpolation or model fitting on these elevation information, the overall elevation state of the highway can be inferred. By using geographic information system tools, the inferred elevation data can be compared with the existing geographic data to form a comprehensive road surface elevation map;

[0070] Specifically, using the elevation data of known geographical locations, the elevation distribution of the entire road or area is estimated and inferred through a raster model. This process can generate a continuous elevation model, reflecting the overall elevation state of the road.

[0071] S2: Set a time comparison domain to analyze the relationship between current elevation data and historical elevation data. By comparing, the abnormal points of elevation change are predicted, and then the potential risks of subgrade diseases, such as subgrade settlement, uplift or deformation, etc., are speculated;

[0072] Specifically, to set a time comparison domain to analyze the relationship between current elevation data and historical elevation data, first, the time frame for comparison needs to be defined. For example, set the elevation data of the most recent year to be compared with that of the past five years. Next, collect the elevation data during this period and perform preprocessing to ensure the accuracy and consistency of the data. Data analysis can calculate the difference between the current elevation and the historical elevation, and use the Z-score to identify significant changes and mark the abnormal points. Then, for these abnormal points, combined with time series analysis methods (moving average, trend analysis), explore their change trends, so as to speculate on potential subgrade disease risks, such as settlement, uplift or deformation, etc. Finally, establish a visualization tool to intuitively display the elevation change and the disease risk area.

[0073] S3: Analyze traffic flow data. By collecting the track data of driving vehicles through sensors and the Beidou system, the lanes with high and low driving frequencies can be identified. Utilize the fact that vehicles may have avoidance behaviors in disease sections, such as reducing speed or changing the driving trajectory, resulting in a significant decrease in the driving frequency on certain lanes. By analyzing this data, the specific locations where diseases may exist are speculated. In addition, combined with historical inspection records and accident occurrence data, evaluate the severity of diseases at these locations, and combine the potential disease locations with other available data (such as elevation change, vibration characteristics) to form a more comprehensive analysis;

[0074] S4: Integrate and output the road health assessment data, risk analysis data, and potential disease location data obtained from the previous analysis. This output can take various forms, such as generating a report, creating a visualization dashboard, or directly updating it into the management system. The output data should include information such as health score, disease type, and risk level, and mark the sections that need to be maintained preferentially.

[0075] Specifically, the methods for predicting and statistically analyzing the elevation and potential diseases of the road through time comparison, elevation comparison, and trajectory data comparison include the following steps:

[0076] S1: Speculate the overall elevation information of the road based on the elevation information predicted by the vehicle body vibration displacement device;

[0077] S2: Set up a time comparison time domain to obtain the current potential subgrade disease risks by comparing the previous elevation data;

[0078] S3: Identify the high-frequency and low-frequency driving lanes by reading the track data, and infer the disease occurrence location based on the disease avoidance characteristics of the vehicle owners;

[0079] S4: Output the road health evaluation data, risk data, and location data to facilitate future maintenance by the staff.
