Embodiment Construction

[0049] Explain the technical solution in conjunction with the accompanying drawings

[0050] Referring to Fig. 1, Fig. 1 shows a computer-centered control system, an image acquisition system and an image analysis system forming a scanning object stage. The control system of the scanning object stage is to control the movement of the stepping motor of the scanning object stage through computer programming, so that it can automatically step and change direction during the scanning process to scan a complete film; the image acquisition system realizes the image under the microscope through the camera and image capture card. Save; the image analysis system is controlled by a program to continuously analyze multiple images.

[0051] Refer to the picture acquisition module in Figure 2-1, adjust the sample to the starting point by setting the limit value, input the name of the picture group to be saved, the program will automatically realize, intercept the picture, change the picture...

Abstract

The apparatus thereof comprises a scanning microscope comprising a scanned-object table; the scanning microscope has a video camera and is connected to the computer; the computer has an image capturing card; the scanned-object is connected to a step motor; the step motor control system is connected to the computer. The method thereof comprises: using the video camera and image capturing card to capture and save the image from the scanning microscope; controlling the step motor to drive the scanned-object to move in order to scan the overall object; sequentially reading out multi images and making statistic analysis; calculating the degree of porosity; saving and displaying the result.

Description

Technical field: [0001] The invention relates to a coke porosity measuring device and a measuring method, in particular to a coke porosity measuring device and a measuring method controlled by a computer. Background technique: [0002] Coke is a porous material, and the pore structure of coke is one of the main factors that determine the performance of coke. It has received extensive attention at home and abroad in recent years. [0003] For the determination of the porosity of other materials, the patent JP2000131220, without contact, detects the transmission signal of the porous substance after infrared irradiation and the previously obtained relationship between the porosity of the porous substance, the thickness of the photosensitive plate, and the visibility of infrared rays. It is suitable for materials with uniform thickness, but not for coke with irregular shapes; patent CN02132500.6 uses the gas state equation, adopts the method of gas movement, and accurately measu...
