Problems solved by technology

The main problems of this test method are: ①The test speed is slow, the efficiency is low, and the operator is prone to fatigue. It takes more than 2 hours; ②During the test process, it is difficult for the operator to strictly follow the specified point and line spacing to test, and the test process has a great influence on the uniformity of the measuring point arrangement; ③The test results cannot be traced back, only the final Statistical results, but can not reflect the uniformity of the measuring point arrangement and whether the measuring points meet the requirements, and the resulting accuracy of the measured value; ④The stability of the photometer caused by the long test process, and the linear range of the photometer The accuracy of a single measurement value caused by the difficulty of wide enough

Embodiment 1、 Embodiment 1

[0034] Example 1, Example 1, a device for detecting the reflectivity of coal or organic rock vitrinite

[0035] A device for detecting the reflectivity of coal or organic rock vitrinite, including an object stage for placing coal or organic rock vitrinite samples and standard samples and a polarizing microscope for imaging the samples, the above object stage can be automatically moved of. The equipment of the present invention also includes a microscopic digital camera and a vitrinite reflectance measuring device, wherein the microscopic digital camera is a device for collecting images formed by a polarizing microscope; The images collected by the micro-digital camera are used for image calling, measuring point layout, vitrinite reflectance measurement, linking, statistics and result output.

[0036] The vitrinite reflectance measuring device includes an image calling module, a measuring point arrangement module, a vitrinite reflectance measuring module, a storage module, a l...

Embodiment 2

[0052] Embodiment 2, multi-frame call by screen and carry out vitrinite reflectance test according to the national standard method

[0053] Adopt the equipment and method that above-mentioned embodiment 1 introduces to carry out coal or organic rock vitrinite reflectance measurement, wherein:

[0054] When the image calling module calls out the images in the microscopic digital camera, it calls out one by one, and the rest of the determination steps are the same as in Example 1.

Embodiment 3

[0055] Embodiment 3, call after image splicing, carry out vitrinite reflectivity test

[0056] The difference between this embodiment and Embodiment 2 lies in that the image calling module is called out after splicing images, and the rest of the steps are identical.

[0057] After image splicing, the operation interface for measuring vitrinite reflectance is called out, as shown in figure 2 shown.

Abstract

The invention discloses equipment for detecting the reflectivity of coal or organic rock vitrinite. The equipment comprises a stand, an imaging device and an image collection device, wherein a coal or organic rock vitrinite sample is placed on the stand, the imaging device images the sample, and the image collection device is used for collecting an image formed by the imaging device. The equipment is characterized by also comprising a vitrinite reflectivity measurement device carrying out image invocation, measuring point arrangement, vitrinite reflectivity measurement, linkage, statistics and result output on the image collected by the image collection device; and the magnification of the imaging device is at least 5 times. The equipment is adopted to carry out reflectivity test, which has simple and convenient procedure, is easy to operate, conforms to the national standard requirement of vitrinite reflectivity test and improves the accuracy and the efficiency of the reflectivity test of coal vitrinite greatly.

Description

technical field [0001] The invention relates to the field of measuring the vitrinite reflectance of coal or organic rocks, in particular to a method and special equipment for detecting the vitrinite reflectance of coal or organic rocks. Background technique [0002] Coal vitrinite reflectance test is a basic test project widely carried out in coal, metallurgy, petroleum, geological and other industries. At present, the method used to test the reflectance of coal vitrinite is to determine the suitable vitrinite particles through the eyepiece according to a certain point and line spacing under the oil immersion objective lens of a polarizing microscope, and use a photoelectric converter (commonly used photomultiplier tube or Charge-coupled array photometer), test the reflected light signal of vitrinite in a certain area of ​​measurement area, and compare it with the reflected light signal of a standard sample with known reflectance under the same conditions, and calculate the ...
