Description

Technical Field

[0001] The present invention relates to the field of control technology, and in particular to a control method and system for silica gel particle production equipment. Background Art

[0002] Silica gel particles are a common adsorbent and desiccant with a wide range of applications, including chemical, pharmaceutical, food, electronics and other fields. Its main component is silicon dioxide (SiO2), which has strong adsorption properties and chemical stability. During the production process of silica gel particles, affected by environmental factors, raw material factors and other factors, the moisture absorbed by the silica gel particles during the production process cannot be in a strictly quantitative state. Therefore, it is necessary to adjust the moisture content of the silica gel particles in real time during the production process, so it is necessary to detect the produced silica gel particles in real time.

[0003] When silica gel particles absorb water, their color changes, causing changes in parameters such as transmittance and weight. The detection of the water content of silica gel particles is carried out through comprehensive calculation of multiple parameters. Among them, for the transmittance of silica gel particles, during the transmittance detection of the product, the method of light flux detection requires the installation of sensors, and has certain accuracy requirements for the position of the product. When using image recognition technology, it is generally through the first photo of the produced product, and then the second photo with backlight, and the transmittance is obtained by comparing the two photos. Since multiple photos are required, the efficiency of silica gel particle production equipment is low, the response of the production line is slow, and it cannot be adjusted in time.

[0080] Figure 1 The present invention is a flow chart of a control method for silica gel particle production equipment.

[0081] Figure 2 This is a schematic diagram of the implementation process of a silica gel particle production equipment control method proposed in the present invention.

[0082] The reference numerals are as follows: 01 - silica gel particles to be detected, 02 - phantom, 03 - auxiliary plane. DETAILED DESCRIPTION

[0083] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0084] The present invention proposes a control method for silica gel particle production equipment, wherein the production equipment includes an image acquisition device, a light source, an auxiliary plane 03 and a controller, wherein the auxiliary plane 03 is a mirror with optical reflection effect, and the method is applicable to the controller, including steps S101-step S104:

[0085] S101: Control the light source to illuminate the auxiliary plane 03 along a first direction, wherein the angle between the first direction and the auxiliary plane 03 is a preset angle, which is not 90°, and the auxiliary plane 03 is used to lay out a number of silica gel particles 01 to be detected.

[0086] See also Figure 2 , Figure 2 The schematic diagram of the implementation process of the embodiment of the present invention is as follows. In the present invention, the light source emits light to illuminate the silica gel particles 01 to be detected placed on the auxiliary plane 03. The light source is set at Figure 2 At A in the figure, the image acquisition device is set at Figure 2 At B in the figure, for the silica gel particles to be detected, a virtual image 02 formed by mirror reflection must be generated in the auxiliary plane 03. In order to ensure that the image can obtain the first image, that is, the image of the silica gel particles themselves, and the image of the virtual image 02 formed by them, that is, the second image, at B, the angle between the first direction and the auxiliary plane 03 should be a preset angle γ that is not 90°, so as to avoid the virtual image 02 formed from overlapping with the image of the silica gel particles themselves.

[0087] S102: Control the image acquisition device to acquire the target image along the second direction, wherein the angle between the second direction and the auxiliary plane 03 is a preset angle, and the second direction and the first direction are located in the same plane.

[0088] It can be understood that in this embodiment, an image acquisition device is set at point B as shown in the figure, and the first image and the second image can be acquired at the same time, that is, the image of the silicone particles to be detected and the image of the virtual image 02 formed by the mirror reflection. Since the light emitted from point A is transmitted through the silicone particles to be detected, the second image is the image of the silicone particles to be detected after being transmitted by the light, that is, the image with backlight, while the first image is the image without backlight. Therefore, by comparing the brightness of the first image and the second image, the light transmittance of the silicone particles can be reflected to a certain extent, which is convenient for the regulation of the subsequent production process. In this embodiment, the target image is the image directly acquired by the image acquisition device at point B.

[0089] S103: Determine a first image and a second image based on the target image, wherein the first image is a direct image of the silica gel particle 01 to be detected, and the second image is a reflected image of the silica gel particle 01 to be detected in the auxiliary plane 03.

[0090] It is understandable that by comparing the brightness of the first image and the second image, the technical effect of determining the light transmittance of the silica gel particles can be achieved. How the machine distinguishes the first image from the second image can be achieved by using steps S1031 to S1035.

[0091] S1031: Segment the target image to form multiple sub-images, wherein the size of the sub-images is much smaller than the size of the silica gel particles 01 to be detected.

[0092] It can be understood that as an implementation method, in the process of processing an image, the image needs to be first divided into multiple sub-images, each of which can be 1*1 pixel, 2*2 pixel, 3*3 pixel, which varies according to the processing power of the machine and is not limited here. The target image is divided into multiple sub-images, and feature recognition or other processing is performed on the multiple sub-images to facilitate subsequent steps.

[0093] S1032: Obtain first visual characteristic parameters of the silica gel particles 01 to be detected under light, where the first visual characteristic parameters include brightness, grayscale, and contrast.

[0094] In this embodiment, the features of each sub-image can be matched with the features of the silica gel particles 01 to be detected, so as to determine the sub-image forming the first image. Since part of the light must be scattered inside when passing through the silica gel particles 01 to be detected, the characteristic parameters of the silica gel particles 01 to be detected under light are obtained, that is, the first visual characteristic parameters. The first visual characteristic parameters are used to characterize the visual characteristics of the silica gel particles 01 to be detected under light. The parameters can be directly input by the user after obtaining them externally through experiments, or can be obtained in other ways, which are not limited here.

[0095] S1033: Obtain the second visual feature parameters of each sub-image, match the first visual feature parameters with the second visual feature parameters, and determine a first target sub-image among the multiple sub-images based on the matching result, where the first target sub-image is a sub-image that forms the first image.

[0096] As an implementation method, in order to facilitate comparison, a first characterization parameter can be introduced , used to comprehensively measure the first identification characteristic parameter composed of multiple data. Specifically, the first characterization parameter It can be calculated by the following formula:

[0097] ;

[0098] in, is the first weight corresponding to brightness, is the second weight corresponding to the grayscale, is the third weight corresponding to the contrast, is the data value of brightness, is the grayscale data value, is the data value of contrast.

[0099] Understandably, , , It can be determined by the user according to the production situation. The first characterization parameter used to comprehensively measure the first identification feature parameter composed of multiple data can be obtained through the above calculation formula. .

[0100] Based on the same principle, for each sub-image, after obtaining its corresponding second visual feature parameter, its corresponding second representation parameter for comprehensively measuring the second recognition feature parameter composed of multiple data can also be obtained. , and satisfy:

[0101] ;

[0102] in, is the data value of the brightness of each sub-image, is the grayscale data value of each sub-image, is the data value of each sub-image.

[0103] Then, the first characterization parameter can be The second characterization parameter For edge alignment, the first characterization parameter The second characterization parameter When the consistency is high, it can be proved that the image features of the corresponding sub-image are the same as the image features of the silica gel particles 01 to be detected under the light, that is, the sub-image of the first image is formed.

[0104] Specifically, as an implementation mode, if the first characterization parameter Greater than the second characterization parameter , then based on the first characterization parameter The second characterization parameter Determine the judgment value, the judgment value satisfies:

[0105] =( - ) ;

[0106] in, is the judgment value;

[0107] If the first characterization parameter Less than the second characterization parameter , then based on the first characterization parameter The second characterization parameter Determine the judgment value, the judgment value satisfies:

[0108] =( - ) ;

[0109] Will Compared with the preset judgment value, if If the second visual feature parameter is less than or equal to a preset determination value, the sub-image corresponding to the second visual feature parameter is determined to be the first target sub-image.

[0110] It is understandable that the preset value can be adjusted according to the actual situation to make the recognition result more accurate and reduce the probability of misrecognition.

[0111] S1034: Determine a first image in the target image based on the multiple first target sub-images.

[0112] It can be understood that, as an implementation mode, after a plurality of first target sub-images are determined, operations such as splicing and fusion are performed on the plurality of target sub-images, so that the first image can be determined in the target image.

[0113] S1035: Based on the first image, determine contour line graphs in the plurality of first images, where the contour line graph is a line graph formed by the contour of each silica gel particle 01 to be detected in the first image.

[0114] It can be understood that, as an implementation method, for the second image, since there is a mirror reflection relationship between the second image and the first image, to a certain extent, the contour in the second image is formed by mirror flipping and then reducing it at a certain ratio. Therefore, in this implementation method, the contour line graph in the first image can be extracted, and the contour line graph is matched with the target image, and the second image can be determined in the target image. How to extract the contour line graph in the first image has been disclosed in the relevant technology and will not be repeated here.

[0115] S1036: Mirror-flipping the multiple contour line images, and fitting the multiple contour line images with the target image, and determining a second image in the target image according to the fitting result.

[0116] Specifically, after the multiple contour line graphs are mirror-flipped, the multiple contour line graphs are completely identical in shape to the contour line graph of the virtual image 02 in the second image. Therefore, by fitting the multiple contour line graphs with the target image, the second image can be determined in the target image. The algorithm used for image fitting has been disclosed in the relevant technology and will not be described in detail here. Through the above steps, the first image and the second image in the target image can be determined.

[0117] S104: Determine the current light transmittance of the silica gel particles 01 to be detected based on the first image and the second image, and adjust the production equipment based on the current light transmittance.

[0118] It can be understood that, since the light emitted from point A is transmitted through the silica gel particles to be detected, the second image is the image of the silica gel particles to be detected after being transmitted by the light, that is, the image with backlight, while the first image is the image without backlight. Therefore, by comparing the brightness of the first image and the second image, the light transmittance of the silica gel particles can be reflected to a certain extent. It should be noted that the light transmittance mentioned in this embodiment is not strictly calculated according to the light flux, but is only used to measure the light transmittance of the silica gel particles in this embodiment.

[0119] Specifically, as an implementation method, since the first image is an image of multiple silica gels to be detected, the first average brightness parameter of the first image can be determined based on the first image, and then the second average brightness parameter of the second image can be determined based on the second image, and the current transmittance can be determined based on the first average brightness parameter and the second average brightness parameter. For the current transmittance, the degree of brightness attenuation can be used to characterize it, or it can be characterized in other ways, which are not limited here. It can be understood that the current transmittance is compared with the preset transmittance. If the current transmittance is less than the preset transmittance, the production equipment is controlled to increase the current transmittance of the silica gel particles 01 to be detected produced by the production equipment. The current transmittance is compared with the preset transmittance. If the current transmittance is greater than the preset transmittance, the production equipment is controlled to reduce the current transmittance of the silica gel particles 01 to be detected produced by the production equipment. In this way, the produced silica gel particles can meet the transmittance requirements.

[0120] A control method for a silica gel particle production device proposed in an embodiment of the present invention first controls the light source to illuminate the auxiliary plane 03 along a first direction, the auxiliary plane 03 is used to lay out a number of silica gel particles 01 to be detected, then controls the image acquisition device to acquire a target image along a second direction, then determines the first image and the second image based on the target image, the first image is a direct image of the silica gel particles 01 to be detected, and the second image is a reflection image of the silica gel particles 01 to be detected in the auxiliary plane 03, finally, determines the current transmittance of the silica gel particles 01 to be detected based on the first image and the second image, and regulates the production device based on the current transmittance. A control method for a silica gel particle production device proposed in an embodiment of the present invention, by providing the auxiliary plane 03, the image acquisition device can simultaneously obtain the image of the silica gel particles without backlight and the image of the silica gel particles with backlight in the acquired single image, and by comparing the two images, the transmittance of the silica gel particles can be obtained, which is more efficient and faster than irradiating the silica gel particles with backlight and taking multiple images, and the production equipment can respond more quickly.
