Description

Technical Field

[0001] The present invention relates to the field of data analysis, and particularly to an intelligent analysis system based on multi-source big data fusion. Background Art

[0002] In the process of urban environmental management, in order to reduce the content of particulate matter (such as PM2.5) in urban air, it is necessary to sprinkle water on the particulate matter content area to ensure the air humidity and ground humidity of the area, so that the water in the air can adsorb particulate matter, increase the weight of particulate matter and make it settle quickly, or form a water film on the ground to improve the adsorption capacity of ground particulate matter, so as to achieve the effect of reducing the content of particulate matter in the air.

[0003] The prior art with the publication number of CN116660463A discloses a big data air quality detection and alarm system, including: a plurality of air detection stations for detecting air quality and storing the detection results; a data analysis device for receiving the detection results of the plurality of air detection stations. The data analysis device includes a data preprocessing module and a data analysis module. The data preprocessing module is used to sort out and summarize the received detection results, and the data analysis module analyzes the sorted and summarized detection results. This kind of big data air quality detection and alarm system can realize information data sharing in air quality detection and alarm through big data technology, give full play to the value of atmospheric environment monitoring data, and in the process of big data application, big data and detection data can be combined, and with the help of the constructed big data model, the detection results can be presented intuitively, so as to improve the effectiveness of atmospheric environment monitoring data.

[0004] However, due to the differences in the locations to be monitored, the site environments, such as terrain and building conditions, will also be different, resulting in differences in the wind speed at the monitoring locations. Wind speed is also an important factor affecting the content of particulate matter in the air. The differences in air humidity, ground humidity and wind speed at different monitoring locations lead to differences in the ability of different monitoring locations to inhibit particulate matter in the air. Therefore, the intervention timing of the solution to judge whether the particulate matter concentration in the air is greater than the threshold by setting a threshold and determine whether to manually intervene in the particulate matter at the monitoring location to reduce the particulate matter concentration at the monitoring location needs to be further optimized. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent analysis system based on multi-source big data fusion to solve the above deficiencies in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An intelligent analysis system based on multi-source big data fusion, including a particle monitoring module, an air humidity monitoring module, a wind speed monitoring module, a ground humidity monitoring module, a test module, and a data processing module;

[0007] The particle monitoring module is used to monitor the particle concentration in the target area. Among them, the particle monitoring module can use an air quality monitor to monitor the concentration of particulate matter (such as PM2.5, PM10) in the air in real time to achieve the monitoring of the particle concentration in the air; use a laser particle counter to measure the number and concentration of particulate matter with different diameters in the air based on the principle of laser scattering to achieve the monitoring of the particle concentration in the air; use an optical sensor to monitor the concentration of particulate matter through the principle of light scattering or light absorption to achieve the monitoring of the particle concentration in the air;

[0008] The air humidity monitoring module is used to monitor the air humidity in the target area, and a humidity sensor can be used to achieve the monitoring of the air humidity;

[0010] The ground humidity monitoring module is used to monitor the ground humidity in the target area based on machine vision, and the ground humidity includes the height of the ground water volume and the percentage of water content in the ground;

[0011] The test module is used to test the change rate of the particle concentration in the air in the target area under various air humidity, ground humidity and wind speed conditions in the target area.

[0012] Among them, there are multiple particle monitoring modules, air humidity monitoring modules, wind speed monitoring modules and ground humidity monitoring modules, which are distributed at various positions in the target area to facilitate the monitoring of the corresponding data at different positions in the target area, so as to improve the monitoring range and accuracy.

[0013] The data processing module is used to obtain the particle concentration monitored by the particle monitoring module, the air humidity monitored by the air humidity monitoring module, the wind speed monitored by the wind speed monitoring module, and the ground humidity monitored by the ground humidity monitoring module;

[0014] The data processing module is also used to train a machine learning model based on the particle concentration, air humidity and wind speed to obtain an air humidity prediction model, and the air humidity prediction model is used to predict the predicted air humidity that makes the particle suppression effect in the target area reach the set particle change rate threshold through the input particle concentration, wind speed and air humidity; Among them, the present invention does not limit the specific machine learning model, which can be selected according to actual training needs to ensure the accuracy of the trained model;

[0015] Further, the ground humidity monitoring module monitors the ground humidity in the target area based on machine vision, including the following steps:

[0016] A1. Obtain the historical hyperspectral image of the ground in the target area;

[0017] A2. Set multiple ground humidity labels and associate the historical hyperspectral images with the corresponding ground humidity labels respectively;

[0018] A3. Based on the hyperspectral images and ground humidity labels, train a convolutional neural network model to obtain a ground humidity recognition model. The ground humidity recognition model is used to output the corresponding ground humidity label according to the input hyperspectral image. Specifically, in the process of training the convolutional neural network model, the following steps can be carried out:

[0019] a. Data preprocessing: Process the hyperspectral images, including resizing, normalization, denoising, etc., to ensure data consistency and model training effect;

[0020] b. Model selection: Based on the actual situation and considering model complexity and computing resources, select a suitable model architecture. Commonly used CNN architectures include VGG, ResNet, EfficientNet, etc.;

[0021] c. Training dataset division: Divide the data (i.e., hyperspectral images and ground humidity labels) into a training set, a validation set, and a test set according to a certain ratio (such as 6:3:1) to evaluate the generalization ability of the model;

[0022] d. Model training: Use the training set to train the model. The optimization process usually adopts the gradient descent algorithm to adjust hyperparameters such as the learning rate and batch size to improve the model performance;

[0023] e. Model validation: Evaluate the performance of the model on the validation set and adjust the model parameters to avoid overfitting or underfitting.

[0024] d. Testing and evaluation: Evaluate the final effect of the model on the test set and use metrics such as mean squared error (MSE) and root mean squared error (RMSE) to measure the accuracy of the prediction and ensure that the prediction accuracy meets the requirements.

[0028] B1. Prepare a target area where the ground humidity is lower than the set minimum ground humidity threshold and the air humidity is lower than the set minimum air humidity threshold. Monitor and record the air humidity and ground humidity of the target area, and the particle concentration in the target area is the set particle concentration threshold;

[0029] B2. Monitor the particle concentration in the air of the target area under various wind speeds, and obtain a scatter plot of the change of the particle concentration in the air with time at each wind speed under the corresponding air humidity and ground humidity conditions;

[0031] B4. If so, sprinkle water evenly on the target area to increase the ground humidity by the first set amount compared to the previously recorded ground humidity, and record the ground humidity of the target area at this time, then return to B2. Sprinkling water can make the ground wet and form a water film on the ground surface, thereby making dust particles adhere more tightly to the ground and reducing the probability of their being blown up by the wind, thus reducing particles;

[0032] B5. If not, perform regression analysis on each scatter plot to obtain the change rate of the particle concentration in the air under various air humidity, ground humidity, and wind speed conditions.

[0033] Further, the test module is used to test the change speed of the particle concentration in the air of the target area under various air humidity, ground humidity, and wind speed conditions of the target area, and further includes the following steps:

[0034] C1. Prepare a target area where the ground humidity is lower than the set minimum ground humidity threshold and the air humidity is lower than the set minimum air humidity threshold. Monitor and record the air humidity and ground humidity of the target area, and the particle concentration in the target area is the set particle concentration threshold;

[0035] C2. Monitor the particle concentration in the air of the target area under various wind speeds, and obtain a scatter plot of the change of the particle concentration in the air with time at each wind speed under the corresponding air humidity and ground humidity conditions;

[0036] C3. Determine whether the air humidity in the target area is less than or equal to the set maximum air humidity threshold;

[0037] C4. If so, spray water mist evenly on the target area to increase the air humidity by the second set amount compared to the previously recorded air humidity, and record the air humidity of the target area at this time, then return to C2. Increasing the air humidity can increase the moisture in the air, thereby adsorbing more dust in the air and increasing the weight of the dust, reducing the suspension time of the dust in the air, and thus achieving the effect of suppressing particles;

[0038] C5. If not, perform regression analysis on each scatter plot to obtain the change rate of particle concentration in the air under various air humidity, ground humidity, and wind speed conditions.

[0039] Further, the data processing module is also used to determine whether it is necessary to adjust the air humidity based on the particle concentration, air humidity, and wind speed, including the following steps:

[0040] D1. Obtain the particle concentration, air humidity, and wind speed at each historical moment to obtain sample data;

[0041] D2. Mark the sample data in which the particle concentration drops below the set particle concentration threshold within the set time length under various air humidity and wind speed conditions as the first sample data, and mark the sample data in which the particle concentration drops to be greater than or equal to the set particle concentration threshold within the set time length under various air humidity and wind speed conditions as the second sample data;

[0042] D3. Set normal labels and abnormal labels, associate the normal labels with the first sample data, and associate the abnormal labels with the second sample data;

[0043] D4. Train a first machine learning model based on the first sample data, normal labels, second sample data, and abnormal labels to obtain a particle processing anomaly judgment model, and the particle processing anomaly judgment model is used to output the corresponding normal label or abnormal label based on the input sample data;

[0044] D5. Judge whether the output of the particle anomaly judgment processing model is an abnormal label;

[0045] D6. If so, it is necessary to adjust the air humidity; if not, it is not necessary to adjust the air humidity.

[0046] Further, the data processing module is also used to train a machine learning model based on the particle concentration, air humidity, and wind speed to obtain an air humidity prediction model, and the air humidity prediction model is used to predict the predicted air humidity that enables the particle suppression effect in the target area to reach the set particle change rate threshold by inputting the particle concentration, wind speed, and air humidity, including the following steps:

[0047] E1. Train a second machine learning model based on the first sample data to obtain an air humidity prediction model, and the air humidity prediction model is used to output the predicted air humidity that enables the particle concentration to drop below the particle concentration threshold within the set time length based on the input particle concentration and wind speed;

[0048] E2. If the output of the particle anomaly judgment processing model is an abnormal label, input the particle concentration and wind speed into the air humidity prediction model to obtain the corresponding predicted air humidity.

[0049] Further, the data processing module is further configured to issue a reminder when the particle suppression effect predicted by the air humidity prediction model is lower than the set particle change rate threshold, and is used to sprinkle water on the target area after the staff receives the reminder.

3. The intelligent analysis system based on multi-source big data fusion according to claim 1, characterized in that: The test module is used to test the change rate of the particle concentration in the air in the target area under various air humidity, ground humidity, and wind speed conditions, and specifically includes the following steps: A1. Prepare a target area where the ground humidity is lower than the set minimum ground humidity threshold and the air humidity is lower than the set minimum air humidity threshold, monitor and record the air humidity and ground humidity in the target area, and the particle concentration in the target area is the set particle concentration threshold; A2. Monitor the particle concentration in the air in the target area under various wind speed conditions to obtain a scatter plot of the change of the particle concentration in the air with time at each wind speed under the corresponding air humidity and ground humidity conditions; A3. Determine whether the ground humidity in the target area is less than or equal to the set maximum ground humidity threshold; A4. If so, sprinkle water evenly on the target area to increase the ground humidity by the first set amount compared to the previously recorded ground humidity, and record the ground humidity in the target area at this time, and return to A2. Sprinkling water can make the ground wet and form a water film on the ground surface, which can make the dust particles adhere to the ground more tightly, reducing the probability of their being blown up by the wind, thereby reducing particles; A5. If not, perform regression analysis on each scatter plot to obtain the change rate of the particle concentration in the air under various air humidity, ground humidity, and wind speed conditions.

4. The intelligent analysis system based on multi-source big data fusion according to claim 1, wherein: The test module is used to test the change rate of the particle concentration in the air in the target area under various air humidity, ground humidity, and wind speed conditions, and further includes the following steps: B1. Prepare a target area where the ground humidity is lower than the set minimum ground humidity threshold and the air humidity is lower than the set minimum air humidity threshold, monitor and record the air humidity and ground humidity in the target area, and the particle concentration in the target area is the set particle concentration threshold; B2. Monitor the particle concentration in the air in the target area under various wind speed conditions to obtain a scatter plot of the change of the particle concentration in the air with time at each wind speed under the corresponding air humidity and ground humidity conditions; B3. Determine whether the air humidity in the target area is less than or equal to the set maximum air humidity threshold; B4. If so, spray water mist evenly on the target area to increase the air humidity by the second set amount compared to the previously recorded air humidity, and record the air humidity in the target area at this time, and return to B2. Increasing the air humidity can increase the moisture in the air, thereby adsorbing more dust in the air, increasing the weight of the dust, and reducing the suspension time of the dust in the air, thereby achieving the effect of suppressing particles; B5. If not, perform regression analysis on each scatter plot to obtain the change rate of the particle concentration in the air under various air humidity, ground humidity, and wind speed conditions.
