The application scope and depth of geological environment monitoring services are limited and have not yet fully met social needs. In order to accurately grasp the temporal and spatial distribution laws, changes and development trends of the geological environment, and support the prevention, protection and emergency decision-making of the geological environment, my country has carried out a series of geological environment surveys, monitoring and evaluation work.

Then the related two-dimensional geological models are connected, and the models are continuously corrected and tested in this process, and finally the geological data are presented in the form of three-dimensional images. The labor cost required is low, the data obtained has strong real-time performance, high accuracy, and comprehensive presentation methods, so as to realize the monitoring and research of large-scale geological conditions. It can also generate accurate warning signals to achieve early warning before disasters occur, so as to facilitate early protection measures and reduce losses.

[0037] Figure 2 This is a structural diagram of the geological environment situation analysis system based on multi-scale observation and three-dimensional field model of the present invention. DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] The present invention provides a geological environment situation analysis method based on multi-scale observation and three-dimensional field model, by constructing a dynamic three-dimensional field model of multi-scale observation of the target area, and by analyzing the correlation between each type of data in the geological data and the geological event, and obtaining the element data of the above geological event, and creating a geological event prediction model based on the above element data, based on the geological event prediction model and the dynamic image of the geological environment in the dynamic three-dimensional field model, accurately predicting the occurrence of each of the above geological events, such as Figure 1 As shown, the method includes:

[0040] Step S1: collecting geological data of a target area through a data collection unit, wherein the geological data includes basic geographical data and geological environment data, and the geological environment data includes a variety of environmental data;

[0041] Step S2: constructing a three-dimensional model of the target area based on the remote sensing image in the basic geographic data, and fusing the basic geographic data, the geological environment data and the geological environment dynamic image corresponding to the geological environment data to obtain a dynamic three-dimensional field model of the target area, and periodically updating the geological data and the geological environment dynamic image;

[0042] Specifically, the geological data of the target area is collected by the data collection unit, and the basic geographic data and the geological environment data in the geological data are obtained, wherein the geological environment data at least include mining environment data, soil environment data and water environment data, and the basic geographic data at least include the landform, vegetation, water system, soil, rock, geological structure, animal distribution, climate and natural resources of the target area, so as to provide data support for creating the dynamic three-dimensional field model, and the basic geographic data also include the remote sensing image of the target area, and the three-dimensional model of the target area is constructed based on the remote sensing image. Since the three-dimensional model can only reflect the landform and terrain characteristics of the target area, it is not possible to observe the geological environment of the target area at multiple scales. Therefore, by standardizing the basic geographic data and the geological environment data, the geological environment dynamic image corresponding to the geological environment data is obtained, and the standardized basic geographic data, the geological environment data and the corresponding geological environment dynamic image are fused based on the three-dimensional model to obtain the dynamic three-dimensional field model, and by periodically updating the geological data and the corresponding geological environment dynamic image, the observation effect is improved and the geological development dynamics are grasped in real time.

[0043] Step S3: constructing a geological environment database based on the dynamic three-dimensional field model, and acquiring historical geological data within a predetermined time period before each geological event occurs based on the geological environment database, and acquiring element data affecting each geological event by analyzing the difference between the historical geological data and normal geological data;

[0044] Specifically, based on the above-mentioned geological database, N identical geological events are obtained, and historical geological data within a predetermined time period before each of the above-mentioned geological events occurs are obtained, and by performing a difference operation between the numerical value corresponding to each data type in the N groups of the above-mentioned historical geological data and the corresponding normal numerical value in the normal geological data, N above-mentioned difference results corresponding to each data type in the above-mentioned historical geological data are obtained, and all the above-mentioned difference results are clustered according to the difference size, and cluster clusters are obtained, and the corresponding difference results in the above-mentioned cluster clusters are all greater than a set threshold, and when the number of difference results corresponding to the same data type in the above-mentioned cluster clusters is greater than or equal to N, it means that the above-mentioned data type is related to the above-mentioned geological event. Therefore, the data corresponding to the above-mentioned data type is used as the element data of the above-mentioned geological event, and the same method is used to obtain the element data corresponding to each other geological event. Through the above-mentioned technical solution, the element data corresponding to each geological event can be accurately obtained, so that it is convenient to predict each of the above-mentioned geological events by establishing a geological event prediction model.

[0045] Step S4: creating a geological event prediction model, and training the geological event prediction model through the historical element data corresponding to the geological event in the geological database, and through the historical element data and the corresponding geological event;

[0046] Specifically, the historical element data corresponding to each of the above-mentioned geological events is obtained through the above-mentioned geological database, and the above-mentioned historical element data set is divided into the above-mentioned training data set and the test data set, so as to facilitate better training of the above-mentioned geological event prediction model, and the above-mentioned test data is also divided into multiple test data subsets according to the similarity with the above-mentioned training data set, and the above-mentioned geological event prediction model is tested, and the accuracy corresponding to each test data subset is obtained. Through the above-mentioned technical scheme, not only the trained geological event prediction model can be obtained, but also the accuracy of the above-mentioned geological event prediction model for each element data segment corresponding to the above-mentioned test data subset can be more accurately obtained.

[0047] Step S5: predicting the occurrence of the geological event after the predetermined time period based on the trained geological event prediction model and the element data before the predetermined time period.

[0048] Specifically, by timely predicting the occurrence of the above-mentioned geological events through the above-mentioned geological event prediction model, corresponding measures can be taken in time to prevent the occurrence of geological disasters and avoid unnecessary casualties and property losses.

[0049] Further, obtaining the dynamic three-dimensional model of the target area includes:

[0050] The target area is divided into grids, and the remote sensing images in the basic geographic data are mapped to construct a three-dimensional model of the target area according to the position correspondence between the remote sensing images and the grids;

[0051] The other basic geographic data and the environmental data except the remote sensing image are standardized and annotated into the three-dimensional model, and interpolation is performed at the discontinuous positions of the geological data to obtain continuous geological data;

[0052] Specifically, the target area is divided into grids, and mapping is performed according to the positional relationship between each grid and the remote sensing image of the target area, so as to construct the three-dimensional model of the target area. Since the three-dimensional model can only reflect the landform and terrain features of the target area, and cannot observe the geological environment of the target area at multiple scales, the formats and units of the other basic geographic data and the environmental data other than the remote sensing image are standardized to facilitate data fusion. The other basic geographic data and the environmental data are also annotated in the three-dimensional model, that is, annotated at the corresponding positions in the three-dimensional space of the three-dimensional model, and at the positions where the geological data are discontinuous, the first position with the highest similarity and the closest distance to the discontinuous position is found, and the geological data at the first position is used to interpolate the geological data at the discontinuous position, so as to obtain continuous geological data. Through the above technical solution, a foundation is laid for further data fusion and obtaining dynamic images of the geological environment corresponding to each geological environment.

[0053] The geological environment data corresponding to each grid is integrated with the basic geographic data marked in the three-dimensional model, and the geological environment data within a set time period is input into the corresponding existing neural network model to obtain dynamic images of the geological environment from multiple visual angles;

[0054] The dynamic geological environment image corresponding to each geological environment data is mapped and fused based on the three-dimensional model according to a visual angle to obtain a dynamic three-dimensional field model of the target area.

[0055] Specifically, by fusing the geological environment data corresponding to each of the above-mentioned grids with the above-mentioned basic geographic data, the geological characteristics of the grid can be reflected at multiple scales. The above-mentioned geological environment data within a set time period is also input into the corresponding above-mentioned neural network model to obtain geological environment dynamic images of multiple visual angles corresponding to each of the above-mentioned geological environment data, wherein the above-mentioned neural network model is a trained model. For example, the geological water environment data is input into the corresponding above-mentioned neural network model to output a geological water environment dynamic image. The above-mentioned geological water environment data at least includes: geological water flow velocity, geological water composition, distribution position of geological water and terrain distribution of geological water. The above-mentioned geological water environment dynamic image can reflect the changes in water flow characteristics, water potential distribution and water color within the above-mentioned set time period. The above-mentioned geological environment dynamic images corresponding to different geological environment data are also mapped and fused based on the above-mentioned three-dimensional model according to the same visual angle, and the above-mentioned dynamic three-dimensional field model is obtained. Through the above-mentioned technical solution, it is convenient for users to observe the geological environment of the above-mentioned target area at multiple scales when selecting a set visual angle to view the above-mentioned dynamic three-dimensional field model.

[0056] Furthermore, element data of each of the geological events is obtained, including:

[0057] Constructing a geological database in the target area based on the dynamic three-dimensional field model, wherein the geological database includes a basic geographic database and a plurality of geological environment databases, and the environment database includes continuous geological environment data and dynamic images of the geological environment at multiple visual angles;

[0058] Based on the geological database, N identical geological events are obtained, and historical geological data within a predetermined time period before each geological event occurs are obtained, and a difference operation is performed between a value corresponding to each data type in the N groups of historical geological data and a normal value corresponding to the data type in the corresponding normal geological data, and a difference result corresponding to each data type in the historical geological data is obtained;

[0059] Clustering all the difference results corresponding to the N groups of geological data according to the difference size, when the number of difference results corresponding to the same data type in the clusters where each difference result is greater than a set threshold is greater than or equal to N, taking the data corresponding to the data type in the clusters as the element data of the geological event;

[0060] Similarly, the element data of each other geological event is obtained, where the value range of N is a positive integer greater than or equal to 2.

[0061] Specifically, since the geological data in the above-mentioned dynamic three-dimensional field model are standardized and continuous, the geological database of the above-mentioned target area can be created through the above-mentioned dynamic three-dimensional field model. The geological environment database in the above-mentioned geological database at least includes a mining environment database, a groundwater environment database and a soil environment database. Since the above-mentioned dynamic three-dimensional field model corresponds to a large number of geological data in the same area, and since the same geological event may be formed by the joint action of multiple factors, the above-mentioned historical geological data before the occurrence of N same geological events are obtained based on the above-mentioned geological database, and the corresponding values ​​of each data type in the above-mentioned historical geological data are obtained by performing a difference operation on the values ​​corresponding to each data type in the N groups of the above-mentioned historical geological data and the corresponding normal values ​​in the above-mentioned normal geological data. The N above-mentioned difference results are clustered according to the difference size through all the above-mentioned difference results, and cluster clusters are obtained. The corresponding difference results in the above-mentioned cluster clusters are all greater than the set threshold value, and when the number of difference results corresponding to the same data type in the above-mentioned cluster cluster is greater than or equal to N, that is, the difference between the numerical value corresponding to the above-mentioned data type in each of the above-mentioned historical geological data and the normal numerical value is large, it means that the above-mentioned data type is related to the above-mentioned geological event. Therefore, the data corresponding to the above-mentioned data type is used as the element data of the above-mentioned geological event, and the same method is used to obtain the element data corresponding to each other geological event. Through the above-mentioned technical scheme, the element data corresponding to each geological event can be accurately obtained, so that it is convenient to predict each of the above-mentioned geological events by establishing a geological event prediction model.

[0062] Furthermore, the training of the geological event prediction model includes:

[0063] Creating the geological event prediction model, obtaining a historical element data set corresponding to each geological event through the geological database, dividing the historical element data set into a test data set and a training data set, and training the geological event prediction model through the training data set;

[0064] The test data set is divided into multiple test data subsets according to the similarity with the data in the training data set, and each of the test data subsets is input into the geological event prediction model to obtain an output result, and the accuracy rate corresponding to the test data subset is calculated according to the output result and the geological event corresponding to the test data subset, wherein the number of data in the test data set is less than the number of data in the training data set.

[0065] Specifically, the historical element data corresponding to each of the above-mentioned geological events is obtained through the above-mentioned geological database, and the above-mentioned historical element data set is divided into the above-mentioned training data set and the test data set, wherein the number of data in the above-mentioned test data set is smaller than the number of data in the above-mentioned training data set, so as to facilitate better training of the above-mentioned geological event prediction model, and the above-mentioned test data is also divided into multiple test data subsets according to the similarity with the above-mentioned training data set, and the above-mentioned geological event prediction model is tested, and the accuracy corresponding to each test data subset is obtained. Through the above-mentioned technical solution, not only the above-mentioned geological event prediction model after training can be obtained, but also the accuracy of the above-mentioned geological event prediction model for each element data segment corresponding to the above-mentioned test data subset can be more accurately obtained.

[0066] Furthermore, when the accuracy rate corresponding to the test data subset is less than the set accuracy rate, the first similarity between the test data set and the training data is obtained, and the training data is used as the target training data, and the geological event corresponding to the target training data is used as the target geological event, and when the data collection unit collects new geological data of the target area, the target element data of the target geological event is extracted from the new geological data, and the second similarity between the target element data and the corresponding target training data is calculated, and when the difference between the second similarity and the first similarity is less than or equal to the set difference, the target element data is input into the geological event prediction model, and the prediction result is obtained, and by analyzing the first geological environment dynamic image of the geological environment corresponding to the target geological event in the new geological data and the K second geological environment dynamic images before the first geological environment dynamic image, they are compared with the historical geological environment dynamic images corresponding to the occurrence of the target geological event in chronological order to obtain a similarity sequence, and judging whether the geological event occurs according to the prediction result and the similarity sequence.

[0067] Specifically, when acquiring the new geological data and predicting the target geological event within a predetermined time period in the future, first determine whether the target element data in the geological data falls within the range where the accuracy is less than the set accuracy, for example: 80%, that is, first calculate the second similarity between the target element data in the new geological data and the target training data, and compare the second similarity with the first similarity. When the difference between the two is greater than or equal to the set difference, it is considered that the prediction is accurate. When the difference between the two is less than the set difference, it is considered that the target element data cannot obtain accurate prediction results through the geological event prediction model. When the target geological event occurs, it can be predicted through the target geological event. The geological environment dynamic image is intuitively reflected, for example: mine rock collapse, etc., can be displayed through the mine environment dynamic image. Therefore, the newly acquired first geological environment dynamic image and the K second geological environment dynamic images before the first geological environment dynamic image are compared with the historical geological environment dynamic image, and a similarity sequence is obtained. According to the similarity change of the similarity sequence and the first output result, it is judged whether the target geological event occurs. Through the above technical solution, in the element data segment that the geological event prediction model cannot accurately predict, the similarity sequence and the first output result are further used to make a comprehensive judgment, thereby improving the accuracy of identifying the target geological event.

[0068] Further, judging whether the geological event occurs according to the prediction result and the similarity sequence includes:

[0069] When the similarity in the similarity sequence increases with time, if the prediction result is that the target geological event occurs, it can be determined that the final prediction result of the target geological event will occur after the predetermined time period; the similarity in the similarity sequence increases with time; if the prediction result is that the target geological event does not occur, when the first similarity data in the similarity sequence is greater than a set value, it can be determined that the final prediction result of the target geological event will occur after the predetermined time period, otherwise the target geological event does not occur.

[0070] Specifically, since the similarity sequence is obtained by comparing the second geological environment dynamic image and the first geological environment dynamic image arranged in chronological order with the historical geological environment dynamic image, the similarity sequence is also a time series. When the similarity in the similarity sequence increases with time, it indicates that the possibility of the occurrence of the target geological event is increasing. Although the prediction accuracy of the geological event prediction model is not high at the newly acquired element data position, it also has a certain reference value. When the similarity sequence and the prediction result both indicate that the target geological event may occur, it is considered that the final result of the target geological event will occur after the predetermined time period. However, when the prediction result is that the target geological event will not occur, the two are contradictory. Since the prediction result is not accurate, and the smallest similarity in the similarity sequence is greater than the set value, that is, each geological environment dynamic image in the similarity sequence is similar to the historical geological dynamic image, it is also considered that the final prediction result of the target geological event will occur after the predetermined time period. Otherwise, it will not occur. Through the technical solution, the target geological event can be further accurately predicted.

[0071] Furthermore, by inputting the element data acquired within the predetermined time into the geological event prediction model, when the output result is that the geological event will occur, corresponding measures are taken to prevent the occurrence of geological disasters.

[0072] Specifically, by timely predicting the occurrence of the above-mentioned geological events through the above-mentioned geological event prediction model, corresponding measures can be taken in time to prevent the occurrence of geological disasters and avoid unnecessary casualties and property losses.

[0073] Furthermore, the geological environment data at least includes mining environment data, soil environment data and water environment data, and the basic geographic data at least includes the landform, vegetation, water system, soil, rock, geological structure, animal distribution, climate and natural resources of the target area.

[0074] The present invention also provides a geological environment situation system based on multi-scale observation and three-dimensional field model, the system is used to implement the above method, such as Figure 2 As shown, the system comprises:
