[0041] Example 1

[0042] In view of the characteristics of the magnetic exploration course that the professional theoretical knowledge is obscure and difficult to understand and has strong practicality, in order to improve the interactive teaching effect, the embodiment of the present disclosure provides a magnetic exploration course simulation teaching system 100.

[0043] For details, see Figure 1 The magnetic exploration course simulation teaching system 100 includes a basic knowledge module 110, a course experiment module 120 and a field practice module 130, which can realize the functions of calling and browsing teaching courseware and dynamic teaching materials, magnetometer simulation operation, real-time forward and inverse calculation and analysis of magnetic anomalies of magnetic bodies, and field data processing.

[0044] In one implementation, the basic knowledge module 110 , the course experiment module 120 , and the field practice module 130 are constructed based on MATLAB Web App.

[0045] MATLAB Web App is a MATLAB application that can run in a web browser. In MATLAB, the App developed by the Application Designer can be compiled into a Web App through the Web App Compiler and deployed in the MATLAB WebApp Server, so that each Web App will have a unique Global Resource Locator (URL).

[0046] The main technical advantages of Web App are: first, it fully adopts object-oriented programming and has good encapsulation; second, it has rich components and is compatible with HTML5, which can easily integrate web pages, multimedia, MATLAB mathematical calculations, and MATLAB graphics and animations; third, the client can access Web App in the browser through the URL without any configuration. The embodiment of this application makes full use of the technical advantages of Web App, which can deeply integrate online teaching and online experiments, and is suitable for online learning and interactive teaching.

[0047] like Figure 2 As shown, the content of the basic knowledge module 110 includes: magnetic exploration, earth magnetic field, rock magnetism, magnetic survey instruments, field magnetic survey working methods, magnetic anomaly processing and conversion, magnetic anomaly forward modeling and inversion, and magnetic anomaly geological interpretation and application.

[0048] In one embodiment, the basic knowledge material includes at least one of picture material, text material and video material;

[0049] The basic knowledge module is also used to call the image material through the image control of MATLAB App designer; the basic knowledge module is also used to obtain the text material through the TextArea control of MATLAB App designer; the basic knowledge module is also used to call the video material through the HTML UI component of MATLAB.

[0050] The basic knowledge module is presented in the form of teaching videos, pictures, animations, cases and text, and packaged into a basic knowledge material library for preset function calls. Because the pictures and videos used in the basic knowledge of this course do not need to be changed frequently and the number is not large, the materials needed for teaching can be directly placed in the Video and Picture files, and the Image control and uiimage function of Matlab appdesigner can be used to set the location, source and other information of the inserted picture. You can also use the TextArea control to obtain multiple lines of text input from the outside world, and use its properties to control the appearance and behavior of the text area. Currently, app designer does not have a Video control, and the VideoReader function in the GUI reads too slowly. Therefore, you can use Matlab's HTML component and the HTML UI component to call the written html file. The video in the Html file is used <video>Label embedding.

[0051] like Figure 3 As shown, Figure 3 A schematic diagram showing the interface of field magnetic survey working method is shown. Figure 3 Includes knowledge points about field magnetic survey working methods, such as the classification of magnetic exploration methods.

[0052] like Figure 4 As shown, Figure 4 A schematic diagram of the Earth's magnetic field interface is shown, including the knowledge points of the Earth's magnetic field. It can be seen that Figure 4 The interface shown includes text introduction, video introduction and a question-and-answer session for students, which allows interaction with students while teaching.

[0053] In addition, when designing the page of the magnetic exploration course simulation teaching system, TabGroup is also used to segment the chapter content. Figure 4 It includes several chapters, including introduction to the geomagnetic field, macroscopic characteristics of the geomagnetic field, small magnetic needles in the geomagnetic field, geomagnetic elements, composition of the geomagnetic field and geomagnetic map.

[0054] like Figure 5 As shown, Figure 5 A schematic diagram of the structure of the course experiment module provided in the embodiment of the present application is shown. In one embodiment, the plurality of magnetic exploration experiments include: regular magnetic body forward modeling experiment, space domain magnetic anomaly processing and conversion experiment, magnetic frequency domain anomaly processing and conversion experiment, magnetic anomaly feature point inversion experiment and GSM-19T proton magnetometer teaching experiment.

[0055] The following takes the regular magnetic body forward modeling experiment and the magnetic frequency domain anomaly processing and conversion experiment as examples. Figure 6 As shown, Figure 6 A schematic diagram of the regular magnetic body forward modeling experiment interface provided in the embodiment of the present application is shown. The purpose of the regular magnetic body forward modeling experiment is: first, to master the forward calculation method of the magnetic field of simple regular magnetic bodies (such as spheres, horizontal cylinders); second, to understand the general distribution law of the magnetic field of spheres and horizontal cylinders; third, to analyze the factors affecting the magnetic field characteristics of magnetic bodies (such as the geometric parameters of magnetic bodies, magnetic parameters, direction or selection of calculation profile orientation). Students can adjust the parameters of the sphere, such as radius, burial depth, magnetic susceptibility, etc. to observe the main profile, contour map and three-dimensional surface map of the sphere's magnetic field. Through the course experiment module, students can more intuitively understand how the magnetic field around the magnetic body changes after changing the parameters.

[0056] In one embodiment, the course experiment module is further used to obtain external input parameters according to the properties of NumericEditField and Spinner in MATLAB Web App; the course experiment module is further used to adjust the experimental images and experimental data output by each magnetic exploration experiment according to the external input parameters.

[0057] In the forward modeling experiment of regular magnetic bodies, the parameters input from the outside are received through the properties of NumericEditField and Spinner in the app. Then, through the pre-written forward modeling method and drawing function, the screen displayed to students is adjusted based on the parameters input from the outside. For example, click Button to start running, receive parameters through the sphereMagForwardMain function, obtain sphereMagForward (forward magnetic field grid data), draw the main profile through the drawprofile function, draw the contour map through the drawContour function, and draw the three-dimensional surface map through the drawCurvedSurface function. The App design part uses Spinner (fine-tuning control), DropDown (control drop-down list control) and UIAxes (coordinate axis properties).

[0058] In one embodiment, the course experiment module is further used to import an external input image according to uigetfile in MATLAB Web App; the course experiment module is further used to perform a magnetic pole operation on the external input image through a preset magnetic pole function to obtain a magnetic pole image.

[0059] For example, Figure 7 As shown, Figure 7 A schematic diagram of the spatial domain magnetic anomaly processing and conversion experiment interface provided by the embodiment of the present application is shown. In the magnetic pole conversion part of the spatial domain magnetic anomaly processing and conversion experiment, students can import the original magnetic anomaly map, and derive the magnetic pole conversion map after inputting the inclination and declination of the geomagnetic field. Open the file selection box through uigetfile, import the grd file of the original magnetic anomaly, call the pre-stored ReadSurferGrid function to read the grid file, and then use the pre-stored pole conversion function Topole to convert the poles, and finally draw the map through the contour function.

[0060] Figure 8 A structural schematic diagram of a field practice module provided in an embodiment of the present application is shown; the field practice module includes the operation of a simulated proton magnetometer and the processing of field practice data.

[0061] In one embodiment, the course experiment module is also used to display the magnetometer operation manual and play the magnetometer operation demonstration video.

[0062] For example, Fig. 9 As shown, Fig. 9 A schematic diagram of a simulated proton magnetometer interface provided in an embodiment of the present application is shown.

[0063] Take the GSM-19T proton magnetometer as an example. Fig. 9 GSM-19T proton magnetometer interface in ( Fig. 9 ), which can provide the simulated operation process of the GSM magnetometer. In addition, it also includes teaching resources. For example, clicking the button in the upper left corner can provide an operation manual, and the operation demonstration video of the proton magnetometer can be placed in it through the HTML control, and the demonstration video can be watched online. Students can deepen their understanding of the measurement principle of the proton magnetometer through online learning, learn the various function settings and measurement mode selection of the instrument, and master the actual operation of the proton magnetometer and the basic skills of geomagnetic field measurement.

[0064] In this way, even when it is difficult to practice outside, students can master the operation of the proton magnetometer and can get started more quickly when they see the real machine, which helps to improve students' hands-on ability and practical ability. In addition, the field practice module can also be used to process the data collected during field practice.

[0065] This embodiment uses the Matlab App tool to build a magnetic exploration course simulation teaching system, and layout is performed through graphical user interface (GUI) visualization components. When designing the user interface, the visualization components can be dragged and dropped to the design canvas, and then precise layout can be achieved according to the alignment prompts.

[0066] In addition, you can use the code analyzer in the Matlab App tool to automatically check for code problems. You can view warning and error messages about the code when testing the code and modify the magnetic exploration course simulation teaching system based on these messages.

[0067] When students need to use the magnetic exploration course simulation teaching system, they only need to enter the unique URL pointing to the magnetic exploration course simulation teaching system in the browser to access and interact with the teaching system. No other software is needed to run the Web application.

[0068] In addition, the content provided in this embodiment is only for example, and the embodiment of this application can also continue to add functions by modifying pages and codes, such as completing classroom assignments online. The implementation of the magnetic exploration course simulation teaching system helps teachers to arrange professional experimental courses reasonably and scientifically, maximize the school's experimental teaching capabilities, and also helps students master professional experimental skills and flexibly arrange experimental time.
