[0025] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0026] The slurry mixing control method provided by the present invention can be implemented by a software algorithm, and the software algorithm can be implemented in any device with data processing function, such as a processor, a computer or an intelligent mobile device. Figures 1 to 7 The slurry mixing control method of the present invention is described.

[0027] In one embodiment, Figure 1 As shown in FIG, the process steps for implementing the slurry mixing control method are as follows:

[0028] Step 101: Obtain control index information of the slurry and obtain an image of the slurry in the mixing tank.

[0029] In this embodiment, the control index information is used to indicate the mixing condition of the slurry. The control index information is index information obtained by a non-image method. Preferably, the control index information is any index information obtained by monitoring the slurry using a monitoring element such as a density meter, a clean water flow meter, or a large pump speed sensor already in the mixing tank. The control index information can be any one of the liquid level, density, stirring degree, and any other index information of the slurry, as long as the type of the control index information and the image index information are consistent. The control index information and the image index information form a control group with each other. By realizing the mutual comparison processing of the control index information and the image index information, intelligent and efficient mixing control is achieved, and the mixing effect is improved.

[0030] In this embodiment, images of the slurry within the mixing tank can be captured using a monitoring camera on the mixing tank. If the cementing equipment is equipped with a slurry monitoring camera, the slurry image can be captured using the existing camera. When capturing these images, video frames can be periodically captured at preset intervals, with each frame being processed using the method provided herein as an image to be processed. The preset interval can be set based on actual conditions and needs; for example, images can be periodically captured at 10-second intervals.

[0031] Step 102: Recognize the image and obtain image index information of the slurry, wherein the image index information is used to represent the mixing condition of the slurry.

[0032] In this embodiment, image index information within the mixing tank is obtained by image recognition. This image index information is index information obtained from the image. The image index information can be used to indicate the mixing status of the slurry. Furthermore, the image index information can be any of the slurry level, density, agitation, and any other index values, as long as the reference index information and the image index information are of the same type. The reference index information and the image index information form a control group.

[0033] Step 103 : generating mixing control information according to the image index information and the control index information, wherein the mixing control information is used to adjust control parameters in the mixing process.

[0034] In this embodiment, the control index information and the image index information form a control group with each other. By performing a mutual comparison process between the control index information and the image index information, mixing control information for adjusting control parameters in the mixing process is generated.

[0035] Step 104: Transmit the mixing control information to the actuator corresponding to the control parameter.

[0036] In this embodiment, the generated mixing control information is used to adjust the control parameters. After the mixing control information is generated, it is transmitted to the actuator corresponding to the control parameter. The actuator adjusts and executes the control parameter based on the mixing control information, thereby achieving mixing control.

[0037] In one embodiment, when the liquid level change of the slurry in the mixing tank is monitored, the control index information of the slurry is obtained, and the implementation process is as follows: based on the liquid level meter, a first liquid level change value of the slurry within a preset time period is obtained; an image of the slurry in the mixing tank is obtained, and the implementation process is as follows: based on the preset time period, a first image and a second image of the slurry in the mixing tank are obtained; the image is identified to obtain image index information of the slurry, and the implementation process is as follows: based on the first image and the second image, a second liquid level change value of the slurry is obtained; according to the image index information, mixing control information is generated, and the implementation process is as follows: based on the first liquid level change value and the second liquid level change value, the liquid level control information is generated, wherein the liquid level control information is used to adjust the liquid level of the slurry; the mixing control information is transmitted to the actuator corresponding to the control parameter, including: transmitting the liquid level control information to the water valve, wherein the water valve is the actuator corresponding to the liquid level.

[0038] In this embodiment, if the firmware device is equipped with a liquid level meter, the reference indicator information is the first liquid level change value monitored by the liquid level meter, and the image indicator information is the second liquid level change value obtained based on the first and second images. By comparing the first and second liquid level change values, the slurry level can be more accurately controlled, improving the mixing control effect. Furthermore, the liquid level meter can be a radar level meter.

[0039] In this embodiment, during the slurry stirring process, due to the large stirring fluctuations, when using a liquid level meter to obtain the liquid level of the slurry, it is necessary to use the liquid level meter to collect the liquid level multiple times within a preset time period, and then obtain the average value of the liquid level as the first liquid level change value. Therefore, the first liquid level change value obtained by the liquid level meter alone cannot guarantee the real-time performance and accuracy of the first liquid level change value. It should be noted that the preset time period is a time period set according to actual conditions and needs. For example, based on a 10-second duration, multiple consecutive time periods are divided. Each time period is treated as a preset time period.

[0040] In this embodiment, a camera captures first and second images of the slurry in real time based on a preset time period. The first and second images are then recognized to obtain a second liquid level change value. Specifically, the first image is captured at the start of the preset time period, and the second image is captured at the end of the preset time period. The second liquid level change value can be obtained by obtaining corresponding slurry level values ​​from the first and second images. The image recognition process can be implemented using a pre-trained first image processing model. Because the images are captured in real time, the second liquid level change value obtained from the first and second images is more real-time and accurate.

[0041] In order to further improve the control accuracy and control effect, the first liquid level change value and the second liquid level change value are comprehensively processed and compared with each other to obtain liquid level control information.

[0042] In one embodiment, liquid level control information is generated based on the first liquid level change value and the second liquid level change value, including: calculating the liquid level change difference between the first liquid level change value and the second liquid level change value; when the liquid level change difference is less than the first liquid level change threshold, generating the first liquid level control information based on the preset control logic; when the liquid level change difference is greater than or equal to the first liquid level change threshold and the liquid level change difference is less than the second liquid level change threshold, generating the second liquid level control information based on the second liquid level change value, and generating a mild liquid level warning message; when the liquid level change difference is greater than or equal to the second liquid level change threshold, generating the third liquid level control information based on the second liquid level change value, and generating a severe liquid level warning message.

[0043] In this embodiment, the first liquid level change threshold is smaller than the second liquid level change threshold. Both the first liquid level change threshold and the second liquid level change threshold can be set according to actual conditions and needs. Generally speaking, a smaller first liquid level change threshold can ensure that liquid level change errors, liquid level meter measurement errors and / or image processing errors will not cause frequent alarms in the slurry control system; and a larger second liquid level change threshold can ensure that when a large deviation occurs in the liquid level, timely adjustments can be made.

[0044] In this embodiment, since slurry stirring is a dynamic process, there will be a preset control logic to control the changes in ash and water volume. Therefore, when the liquid level change difference is less than the first liquid level change threshold, the first liquid level control information is generated according to the preset control logic to complete the liquid level control, that is, the adjustment of the water valve opening is completed.

[0045] When the liquid level change difference is greater than or equal to the first liquid level change threshold, since image monitoring has higher real-time and accuracy than level meter monitoring during the liquid level monitoring process, the second liquid level change value obtained based on the image is used to generate the second liquid level control information or the third liquid level control information.

[0046] Furthermore, if the liquid level change difference is greater than or equal to the first liquid level change threshold and less than the second liquid level change threshold, indicating that the slurry level fluctuation in the mixing tank is small, second liquid level control information is generated based on the second liquid level change value, and a light liquid level warning message is generated. The light liquid level warning message can be transmitted to a warning light or prompt interface of the cementing equipment, thereby providing a light warning of the liquid level change.

[0047] If the liquid level change difference is greater than or equal to the second liquid level change threshold, indicating significant slurry level fluctuations within the mixing tank, a third liquid level control message is generated based on the second liquid level change value, along with a severe liquid level warning message. This severe liquid level warning message can be transmitted to a warning light or prompt interface on the cementing equipment, providing a severe liquid level change warning to alert personnel to the liquid level and prevent accidents such as slurry overflows.

[0048] In a specific embodiment, Figure 2 As shown in the figure, the liquid level control logic of the slurry in the mixing tank is as follows:

[0049] After the slurry mixing starts, it enters the pre-mixing process;

[0050] After the premixing starts, the water valve opening and the ash valve opening are controlled according to the preset ash and water amounts, and water is added to the mixing tank and ash is discharged;

[0051] During the premixing process, the density of the slurry is monitored by a densitometer to determine whether the density has reached the set value. If not, the premixing process is continued; if it has reached the set value, the automatic mixing process is entered.

[0052] During the automatic mixing process, the liquid level meter is used to roughly determine whether the liquid level change in the mixing tank is greater than the liquid level change threshold within a unit time (i.e., a preset time period). If it is greater, the water valve opening is adjusted directly according to the first liquid level change value measured by the liquid level meter;

[0053] If it is not greater than, the image recognition liquid level process is started, and based on the first liquid level change value and the second liquid level change value, a fine-grained judgment is made as to whether the liquid level is stable. If it is unstable, the water valve opening is fine-tuned based on the second liquid level change value. If it is stable, the stable operation stage is entered.

[0054] In a specific embodiment, Figure 3 As shown, based on the first liquid level change value and the second liquid level change value, the specific logic for finely judging whether the liquid level is stable is as follows:

[0055] During the automatic slurry mixing process, the liquid level is detected by a liquid level meter to obtain a first liquid level change value, and the liquid level is detected by collecting an image of the slurry to obtain a second liquid level change value;

[0056] Determine the change of the liquid level by the difference between the first liquid level change value and the second liquid level change value;

[0057] When the liquid level changes detected by the liquid level meter and the image processing are consistent, that is, when the liquid level change difference is less than the first liquid level change threshold, first liquid level control information is generated based on the preset control logic; and the water valve opening is automatically controlled according to the first liquid level control information;

[0058] When the liquid level changes detected by the liquid level meter and the image processing are slightly inconsistent, that is, when the liquid level change difference is greater than or equal to the first liquid level change threshold and the liquid level change difference is less than the second liquid level change threshold, second liquid level control information is generated based on the second liquid level change value, and a slight liquid level warning message is generated; the water valve opening is controlled according to the second liquid level control information obtained based on the image, and a slight warning is issued through the slight liquid level warning message;

[0059] When the liquid level changes detected by the liquid level meter and the image processing are seriously inconsistent, that is, when the difference in liquid level changes is greater than or equal to the second liquid level change threshold, third liquid level control information is generated based on the second liquid level change value, and a liquid level severe warning message is generated; the water valve opening is controlled according to the third liquid level control information obtained based on the image, and a severe warning is issued through the liquid level severe warning message to remind staff to pay attention to the liquid level;

[0060] After the water valve opening is adjusted once through the first liquid level control information, the second liquid level control information or the third liquid level control information, the liquid level is continuously and finely judged based on the liquid level meter and the image to better maintain a stable construction stage, ensure the safety of the slurry mixing operation, and improve the slurry mixing control effect.

[0061] In one embodiment, when the density of the slurry in the mixing tank is monitored, the control index information of the slurry is obtained, and the implementation process is as follows: obtain a first density value of the slurry collected by the densitometer; identify the image and obtain image index information of the slurry, and the implementation process is as follows: obtain the color difference between the image and the preset density image; based on the color difference, obtain the second density value of the slurry; generate mixing control information based on the image index information, and the implementation process is as follows: generate density control information based on the first density value and the second density value, wherein the density control information is used to adjust the density of the slurry; transmit the mixing control information to the actuator corresponding to the control parameter, including: transmit the density control information to the ash valve, wherein the ash valve is the actuator corresponding to the density.

[0062] In this embodiment, if the firmware device is equipped with a densitometer, the reference indicator information is the first density value monitored by the densitometer, and the image indicator information is the second density value derived from the image. By comparing the first and second density values, the slurry density can be more accurately controlled, improving mixing control. The densitometer can be a mass flow meter capable of measuring fluid density.

[0063] In this embodiment, during the slurry stirring process, the densitometer can detect the density of the slurry in real time to obtain a first density value.

[0064] In this embodiment, when the density of the slurry is different, the color of the slurry also has a certain color difference. Therefore, the camera captures an image of the slurry in real time, and then identifies the color difference of the image to obtain the second density value. Specifically, the identification process can be implemented by a pre-trained second image processing model.

[0065] In order to further improve the control accuracy and control effect, the first density value and the second density value are comprehensively processed and compared with each other to obtain density control information.

[0066] In one embodiment, density control information is generated based on the first density value and the second density value. The specific implementation process is as follows: the density difference between the first density value and the second density value is calculated; when the density difference is less than the first density threshold, the first density control information is generated based on the preset control logic; when the density difference is greater than or equal to the first density threshold and the density difference is less than the second density threshold, the second density control information is generated based on the first density value, and a light density warning message is generated; when the density difference is greater than or equal to the second density threshold, the third density control information is generated based on the first density value, and a heavy density warning message is generated.

[0067] In this embodiment, the first density threshold is smaller than the second density threshold. Both the first density threshold and the second density threshold can be set according to actual conditions and needs. Generally speaking, a smaller first density threshold can ensure that density change errors, densitometer measurement errors and / or image processing errors will not cause frequent alarms in the slurry control system; and a larger second density threshold can ensure that when there is a large deviation in density, timely adjustments can be made.

[0068] In this embodiment, since slurry stirring is a dynamic process, there will be a preset control logic to control the changes in ash and water amounts. Therefore, when the density difference is less than the first density threshold, the first density control information is generated according to the preset control logic to complete the density control, that is, to complete the adjustment of the ash valve opening.

[0069] When the density difference is greater than or equal to the first density threshold, since image detection is based on image color difference during density monitoring and has certain limitations, and densitometer monitoring has higher real-time and accuracy, the first density value collected by the densitometer is used to generate the second density control information or the third density control information.

[0070] Furthermore, if the density difference is greater than or equal to the first density threshold and less than the second density threshold, indicating that the slurry density fluctuation in the mixing tank is small, second density control information is generated based on the first density value, and a slight density warning message is generated. The slight density warning message can be transmitted to a warning light or prompt interface on the cementing equipment, providing a slight warning of density changes.

[0071] If the density difference is greater than or equal to the second density threshold, indicating significant density fluctuations in the slurry mixing tank, a third density control message is generated based on the first density value, along with a severe density warning message. This severe density warning message can be transmitted to a warning light or prompt interface on the cementing equipment, providing a severe density change warning to alert personnel to density fluctuations and prevent slurry density issues that could affect cementing results.

[0072] In a specific embodiment, Figure 4 As shown in the figure, the density control logic of the slurry in the mixing tank is as follows:

[0073] After the slurry mixing starts, it enters the pre-mixing process;

[0074] After the premixing starts, the ash valve opening and the ash valve opening are controlled according to the preset ash and water amounts, and water is added to the mixing tank and ash is discharged;

[0075] During the premixing process, the density of the slurry is monitored by a densitometer to determine whether the density has reached the set value. If not, the premixing process is continued; if it has reached the set value, the automatic mixing process is entered.

[0076] During the automatic mixing process, the density meter is used to roughly determine whether the density change of the slurry in the mixing tank per unit time is greater than the density change threshold. If it is greater, the ash valve opening is directly adjusted according to the first density value measured by the density meter.

[0077] If it is not greater than, the image recognition density process is started, and based on the first density value and the second density value, a fine-grained judgment is made as to whether the density is stable. If it is unstable, the ash valve opening is fine-tuned based on the first density value. If it is stable, the stable operation stage is entered.

[0078] In a specific embodiment, Figure 5 As shown, based on the first density value and the second density value, the specific logic for fine-tuning the determination of whether the density is stable is as follows:

[0079] During the automatic slurry mixing process, the density is measured by a densitometer to obtain a first density value, and the density is measured by collecting an image of the slurry to obtain a second density value;

[0080] Determine the density change by the density difference between the first density value and the second density value;

[0081] When the density changes detected by the densitometer and the image processing are consistent, that is, when the density difference is less than the first density threshold, first density control information is generated based on the preset control logic; and the ash valve opening is automatically controlled according to the first density control information;

[0082] When the density changes obtained by the densitometer and the image processing detection are slightly inconsistent, that is, when the density difference is greater than or equal to the first density threshold and the density difference is less than the second density threshold, second density control information is generated based on the first density value, and a slight density warning message is generated; the ash valve opening is controlled according to the first density control information obtained by the densitometer, and a slight warning is issued through the slight density warning message;

[0083] When the density changes obtained by the densitometer and the image processing detection are seriously inconsistent, that is, when the density difference is greater than or equal to the second density threshold, a third density control information is generated based on the first density value, and a density severe warning information is generated; the ash valve opening is adjusted according to the third density control information obtained by the densitometer, and a severe warning is issued through the density severe warning information to remind staff to pay attention to the density;

[0084] After the ash valve opening is adjusted once through the first density control information, the second density control information or the third density control information, the density is continuously and finely judged based on the density meter and the image to better maintain a stable construction stage, ensure the safety of the mixing operation, and improve the mixing control effect.

[0085] In one embodiment, when the agitation degree of the slurry in the mixing tank is monitored, the control index information of the slurry is obtained, and the specific process is as follows: obtain at least one preset agitation image, wherein each preset agitation image corresponds to a preset agitation degree; identify the image and obtain the image index information of the slurry, and the specific process is as follows: determine the agitation degree corresponding to the image by comparing the image with at least one preset agitation image; generate mixing control information based on the image index information, and the specific process is as follows: generate agitation control information based on the agitation degree, wherein the agitation control information is used to adjust the agitation degree of the slurry; transmit the mixing control information to the actuator corresponding to the control parameter, and the specific process is as follows: transmit the agitation control information to the stirring pump, wherein the stirring pump is the actuator corresponding to the agitation degree.

[0086] In this embodiment, the control index information is a preset stirring image, and the image index information is an image captured by the image acquisition device. The purpose of slurry stirring is to fully mix water and ash. The higher the stirring degree, the better the mixing degree of the slurry. In order to better detect the stirring degree, the slurry image obtained in real time can be compared with the preset stirring image. The preset stirring image can be obtained by classifying and marking images with different stirring degrees in history, and each preset stirring image is respectively set with a corresponding preset stirring degree. The image of the slurry is compared with each preset stirring image to determine the preset stirring image with the highest similarity, and the preset stirring degree corresponding to the preset stirring image with the highest similarity is used as the stirring degree of the slurry image. This comparison process can be completed by a pre-trained third image processing model, and the third image processing model can be trained by images with different stirring degrees in history.

[0087] In this embodiment, after the stirring control information is generated according to the stirring degree, the stirring control information is transmitted to the stirring pump to adjust the operating speed of the stirring pump, thereby controlling the speed of the stirrer in the mixing tank.

[0088] In a specific embodiment, Figure 6As shown in the figure, the control logic of the slurry stirring degree is as follows:

[0089] After the slurry mixing starts, it enters the pre-mixing process;

[0090] After the premixing process begins, the image is used to determine whether the slurry is sufficiently stirred. That is, the stirring degree is obtained from the image and it is determined whether the stirring degree is greater than a preset stirring threshold. If it is greater than, it indicates that the stirring is sufficient. If it is not greater than, it indicates that the slurry is not sufficiently stirred.

[0091] If the stirring is not sufficient, the pre-mixing process will continue until the stirring is sufficient, and then enter the automatic mixing process;

[0092] During the automatic mixing process, image recognition is continuously used to determine whether the slurry is sufficiently stirred. That is, the image is compared with multiple preset stirring images to determine whether the stirring degree obtained through the image is greater than the preset stirring threshold. If it is greater, the stable operation stage is entered. If not, the stirring control information is generated according to the stirring degree, and the stirring control information is transmitted to the stirring pump to complete the adjustment of the stirring degree.

[0093] In this embodiment, the detection of the stirring degree can be performed continuously through images to improve the mixing control effect.

[0094] During the above process, if the slurry is not stirred sufficiently, a stirring degree warning message can be generated based on the stirring degree to prompt the staff to pay attention to the stirring degree of the slurry.

[0095] Based on the above embodiment, after obtaining an image of the slurry in the mixing tank, the different processing processes provided in the above embodiment can be performed through the image, so as to simultaneously monitor and adjust the liquid level, density and stirring degree of the slurry to ensure the comprehensiveness of the mixing control.

[0096] Furthermore, the ash valve in the cementing equipment controls the amount of ash discharged, which in turn affects the density of the slurry. Low density increases the ash valve opening, which in turn increases density; high density decreases the valve opening, which in turn decreases density. The water valve in the cementing equipment controls the amount of water, which in turn affects the slurry level. Low levels increase the water valve opening, which in turn raises the level; high levels decrease the water valve opening, which in turn lowers the level. The amount of ash discharged has a minimal impact on the slurry level, so adjusting the slurry level primarily involves adjusting the water valve opening.

[0097] Furthermore, adjusting the water valve opening affects the density of the slurry. After the density changes, the ash valve opening is adjusted again using the method provided in the above embodiment to ensure that the density remains stable. For example, if the current liquid level in the mixing tank is 30% and the preset liquid level is 50%, the water valve opening must be increased in this case to increase the slurry level in the mixing tank. At this point, the slurry density will inevitably decrease, and the densitometer will detect a decrease in density, so the ash valve opening must be increased to increase the density. Therefore, the slurry mixing control process requires maintaining dynamic stability.

[0098] In one embodiment, the cementing equipment is equipped with a video monitoring system, and the image of the slurry in the mixing tank can be captured by a camera in the video monitoring system to implement the slurry mixing control method provided in any of the above embodiments. Figure 7 As shown, the video surveillance system includes a super brain (intelligent data processing device), a display, a switch, an audible and visual alarm, an actuator and at least one camera.

[0099] In this embodiment, an image of the slurry in the mixing tank is captured by any camera and transmitted to the super-brain via a switch. The super-brain processes the image and monitors the image index information of the slurry. When monitoring the liquid level change of the slurry in the mixing tank, the super-brain is also connected to a liquid level meter, and the actuator is a water valve. The super-brain is used to generate liquid level control information based on the first liquid level change value and the second liquid level change value, and transmit the liquid level control information to the water valve via a display. If the super-brain simultaneously generates a mild liquid level warning message or a severe liquid level warning message, the super-brain transmits the mild liquid level warning message to the display or an audible and visual alarm for display, or transmits the severe liquid level warning message to the display or an audible and visual alarm for display.

[0100] When monitoring the density of the slurry in the mixing tank, the super brain is also connected to the density meter, and the actuator is the ash valve. The super brain is used to generate density control information based on the first density value and the second density value, and transmit the density control information to the ash valve through the display. If the super brain generates a light density warning message or a heavy density warning message at the same time, the super brain will transmit the light density warning message to the display or the sound and light alarm for display, or the super brain will transmit the heavy density warning message to the display or the sound and light alarm for display.

[0101] When monitoring the agitation degree of the slurry in the mixing tank, the super brain pre-stores at least one preset agitation image and the preset agitation degrees corresponding to each preset agitation image. The actuator is a stirring pump. The super brain is used to generate agitation degree control information according to the agitation degree value, and transmit the agitation degree control information to the stirring pump through the display. If the super brain generates agitation degree warning information at the same time, the super brain will transmit the agitation degree warning information to the display or the sound and light alarm for display.

[0102] The mixing control method provided by the present invention obtains control index information of the slurry and obtains an image of the slurry in the mixing tank. Then, the image is identified to obtain image index information of the slurry. Based on the image index information and the control index information, mixing control information is generated, and the mixing control information is transmitted to the actuator corresponding to the control parameter. In the above process, the image index information and the control index information are automatically obtained through the image in the mixing tank, and the mixing control information is generated. Based on the mixing control information and the control index information, the automatic control of the mixing process is completed, and the intelligent mixing control process is realized, avoiding the use of a large amount of manual labor, and improving the control effect and control efficiency of the mixing control. At the same time, through the intelligent control process of the image, the safety hazards in the manual processing process can be avoided, and the safety of the mixing process can be improved.

[0103] The present invention processes the monitoring images through the image recognition software within the super brain. By comparing the image status in real time, the changes in the liquid level in the mixing tank can be obtained, which can be verified with the corresponding sensor to further ensure the quality of the mixing. Specifically, the agitation degree of the slurry in the mixing tank is observed through images and compared with the preset agitation images in the background related big data to ensure that the cement slurry is fully stirred. The color difference of the slurry is compared with the image to complete the complementary verification of the slurry density with the densitometer. When an abnormality occurs, the control system will adjust the mixing process in combination with the monitoring elements and image recognition results, and will directly issue an alarm when the abnormality is obvious.
