[0040] Figure 2 A structural schematic diagram of a vitrinite maximum reflectance measuring device for coal is provided for an exemplary embodiment of the present disclosure.

[0041] Figure 3 A structural schematic diagram of an electronic device is provided for an exemplary embodiment of the present disclosure. DETAILED DESCRIPTION

[0042] In order for those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below in conjunction with the accompanying drawings.

[0043] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The implementation described in the following exemplary embodiments does not represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with some aspects of the present disclosure.

[0044] It should be noted that the user information involved in the present disclosure includes but is not limited to user equipment information and user personal information; the collection, storage, use, processing, transmission, provision and disclosure of user information in the present disclosure comply with the provisions of relevant laws and regulations, and do not violate public order and good customs.

[0045] At present, whether it is a photometer method or an image method, the vitrinite maximum reflectance measuring method of coal is to rotate the sample stage, and the maximum reflectance value is determined or recorded when the maximum reflectance value is displayed. The determination steps are: moving the sample stage, finding the vitrinite of coal in the microscope eyepiece or computer video window. Adjust the position of the sample stage so that the center of the field of view is the target vitrinite. Rotate the circular sample stage manually or through software. Record the maximum reflectance value of the target vitrinite during the rotation of the sample stage. Move to the next position and continue to determine the maximum reflectance value of the next vitrinite. Until the measurement points cover the sample surface and the number of measurement points meets the corresponding national standard.

[0046] Wherein, the rotation of the rotation stage inevitably causes the position of the image center point to deviate, if there is no X-Y axis moving device on the rotation stage, the sample does not move according to the fixed point row distance, and the representative of the test point is poor; if there is an X-Y axis moving device on the rotation stage, due to the uneven weight of the rotation stage and the power supply line on the rotation stage, the center point of the image deviates greatly during rotation, and the power supply line limits the movement of the circular rotation stage, affecting the test accuracy; the rotation stage has a small area, and generally only one sample is placed; multiple samples cannot be continuously measured; the rotation stage takes a long time, and the test efficiency is low.

[0047] To solve the above technical problems, in some embodiments of the present disclosure, a micro motor is controlled to drive a microscope polarizer to rotate, so that the polarized light and the vitrinite texture direction are relatively rotated; wherein the microscope polarizer is fixedly connected to the microscope and connected with the micro motor; a stage is controlled to move according to a set motion track, so that the stage reaches a specified test position, and the reflectivity of the vitrinite in the window image is measured; the present disclosure realizes the relative rotation of the polarized light and the vitrinite texture direction through the rotation of the microscope polarizer, reduces the error of the measurement of the maximum reflectivity of the vitrinite of coal caused by the rotation of the existing stage, improves the efficiency of the measurement of the maximum reflectivity of the vitrinite of coal, and improves the accuracy.

[0048] The technical solutions provided by the embodiments of the present disclosure are described in detail below with reference to the drawings.

[0050] S101: a micro motor is controlled to drive a microscope polarizer to rotate, so that the polarized light and the vitrinite texture direction are relatively rotated; wherein the microscope polarizer is fixedly connected to the microscope and connected with the micro motor;

[0051] S102: a stage is controlled to move according to a set motion track, so that the stage reaches a specified test position, and the reflectivity of the vitrinite in the window image is measured.

[0052] In this embodiment, the execution subject of the above method can be a terminal device or a server.

[0053] The terminal device includes, but is not limited to, a mobile station (MS), a mobile terminal, a mobile telephone, a handset, a portable equipment, and the like.

For example, the terminal device can be a mobile phone (also referred to as a "cellular" phone), a computer with wireless communication functions, and the like. The terminal device can also be a computer with wireless transceiver functions, a virtual reality (VR) terminal device, an AR terminal device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical treatment, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, and the like.

The terminal device can be referred to by different names in different networks, for example, a user equipment, a mobile station, a subscriber unit, a station, a cellular phone, a personal digital assistant, a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop station, a television, and the like. For the sake of convenience, the terminal device is referred to as a terminal device in the embodiments.

[0054] In the embodiments, the implementation form of the server is not limited. For example, the server can be a conventional server, a cloud server, a cloud host, a virtual center, or the like. The server mainly includes a processor, a hard disk, a memory, a system bus, and the like, and has a general computer architecture type.

[0055] In the embodiments of the present disclosure, the micro motor is controlled to drive the microscope polarizer to rotate, so that the polarized light is relatively rotated with the vitrinite texture direction; the microscope polarizer is fixedly connected to the microscope and connected with the micro motor; the objective table is controlled to move according to a set motion track, so that the objective table reaches a specified test position, and the reflectivity of the vitrinite in the window image is measured; the present disclosure realizes the relative rotation of the polarized light and the vitrinite texture direction through the rotation of the microscope polarizer, reduces the error of the measurement of the maximum reflectivity of the vitrinite of coal caused by the rotation of the objective table, improves the efficiency of the measurement of the maximum reflectivity of the vitrinite of coal, and improves the accuracy.

[0056] The present disclosure provides a system for measuring the maximum reflectance of vitrinite in coal, comprising: a microscope, a microscope polarizer, and an automatic scanning stage controller. The microscope is used to locate the vitrinite in the coal placed on a stage; the microscope polarizer is fixedly connected to the microscope and connected to a micromotor, rotating under the drive of the micromotor to allow polarized light to rotate relative to the vitrinite texture direction; the automatic scanning stage controller is communicatively connected to the micromotor, controlling the rotation of the micromotor and the movement of the stage according to a set motion trajectory, so that the stage reaches a specified test position and measures the reflectance of the vitrinite in the window image. The rotation of the microscope polarizer is controlled by a micromotor and connected to the automatic scanning stage controller. The automatic scanning controller can control the XYZ axis movement and the rotation of the polarizer, and is centrally controlled by scanning software. The present disclosure manufactures a rotatable microscope polarizer. Rotation of the microscope polarizer also achieves relative rotation of the polarized light and the vitrinite texture direction, avoiding test errors caused by image center position offset that may be caused by rotating the stage.

[0057] It should be noted that the present disclosure does not adopt a rotating stage, so a larger square stage can be configured. The square stage can hold multiple samples, and can measure the maximum reflectance of the coal vitrinite as well as the random reflectance of the coal vitrinite continuously and automatically.

[0058] It should be noted that the present disclosure provides multiple designated test positions. When the stage reaches a designated test position, a window image is used to determine whether vitrinite meeting the test requirements is present. The window image can be a microscope eyepiece image or a computer video window image. Specifically, the designated test positions include: a first test position and a second test position.

[0059] It should be noted that meeting the test requirements means that the vitrinite particles identified through the image window at the designated test location have specific morphology, optical properties and spatial distribution characteristics and meet the experimental objectives (such as reflectance measurement, maturity assessment, etc.).

[0060] In some embodiments of the present disclosure, the stage is controlled to move along a set motion trajectory so that the stage reaches a designated test position, and the reflectivity of the vitrinite in the window image is measured. One achievable method is to control the stage to move along the set motion trajectory; when the stage reaches a first test position, whether vitrinite meeting the test requirements is present in the window image; if vitrinite meeting the test requirements is present in the window image, the reflectivity of the vitrinite in the window image is measured. If vitrinite meeting the test requirements is not present in the window image, the stage is controlled to continue moving to a second test position to continue determining whether vitrinite meeting the test requirements is present in the window image.

[0061] In the above embodiment, if vitrinite meeting the test requirements is present in the window image, the reflectivity of the vitrinite in the window image is measured. One possible implementation method is to trigger the area of ​​the window image containing the vitrinite, control the movement of the stage to move the vitrinite to the test area at the center of the image; control the micromotor to move in the Z-axis direction for focusing; and control the polarizer of the microscope to rotate one revolution at a set rate, and record the maximum reflectivity value. If vitrinite meeting the test requirements is present in the window image, clicking the vitrinite with a mouse automatically adjusts the stage's position, moves the vitrinite to the test area at the center of the image, adjusts the Z-axis focus until the image is clear, rotates the polarizer one revolution at a set rate, and records the maximum reflectivity value. After the measurement is completed, the stage moves to the next position.

[0062] In an exemplary embodiment, the motion trajectory is set to a zigzag trajectory with a fixed point spacing. The stage is controlled to move according to the set motion trajectory. One achievable way is to control the stage to move according to the zigzag trajectory with a fixed point spacing. By setting the motion trajectory of the stage to a zigzag trajectory with a fixed point spacing, and controlling the stage to move according to this trajectory, the sample detection efficiency and uniform coverage can be significantly improved. It should be noted that in addition to the zigzag trajectory with a fixed point spacing, the present disclosure can also use a variety of other types of motion trajectories to control the movement of the stage. The specific selection depends on factors such as the application scenario, sample characteristics, detection targets, and equipment performance. For example, a line-by-line scanning trajectory, a spiral trajectory, a random walk trajectory, an adaptive trajectory, and the like.

[0063] In some embodiments of the present disclosure, after the vitrinite reflectance measurement is completed at all designated test locations, a maximum reflectance test report is generated based on the maximum reflectance value of each designated test location. After the vitrinite reflectance measurement is completed at all designated test locations, the present disclosure generates a maximum reflectance test report based on the maximum reflectance value of each test location. This process significantly improves the accuracy and efficiency of coal rock analysis and organic matter maturity assessment. The automated system accurately locates and measures each test point, ensuring the comprehensiveness and consistency of data collection. This method not only reduces human operating errors, but also significantly shortens the data analysis cycle.
