[0073] In the related art, recycled asphalt concrete is an environmentally friendly building material that is produced by recycling old asphalt pavement materials, undergoing a series of treatments (such as heating, screening, and adding new asphalt or asphalt mixture additives) to produce new concrete, and reused in pavement construction. Since the density of the recycled old asphalt is greater than that of the new asphalt, it is easy to concentrate on one side during the mixing process with the new asphalt, resulting in uneven mixing. When the recycled asphalt concrete with uneven mixing is used for the pavement, it is easy to reduce the bearing capacity of the pavement, resulting in a decrease in service life.

[0074] To solve the above problems, the embodiment of the present application provides a method and device for controlling the production of recycled asphalt concrete. In this method, by first obtaining the mixing information including the new asphalt quality information of the new asphalt required for the production of recycled asphalt concrete and the old asphalt quality information of the old asphalt, it is determined how much weight of recycled asphalt concrete to produce and the proportion of new asphalt and old asphalt in the produced recycled asphalt concrete, so as to avoid the waste caused by the production of too much recycled asphalt concrete and provide a basis for subsequent steps. Then, based on the mixing information and the mixing equipment information, the mixing state information including the information reflecting the mixing state of the new asphalt and the old asphalt in the mixing equipment is obtained, and the mixing distribution of the new asphalt and the old asphalt in the mixing equipment is monitored and determined in real time, providing a basis for subsequent steps. Then, based on the mixing state information, the mixing equipment is controlled to produce recycled asphalt concrete, so that the new asphalt and the old asphalt are mixed evenly, avoiding the problem that the bearing capacity of the road surface is reduced and the service life of the road surface is reduced due to the uneven mixing of the recycled old asphalt and the new asphalt.

The conveying device is a transportation device that can transport asphalt into the mixing device. For example, the conveying device can be an asphalt conveying pipeline, an asphalt station belt, etc., but not limited to this. The mixing device is a device that can heat and stir the asphalt. For example, the mixing device can include a mixing barrel, a stirring device, and a heating device, etc., but not limited to this. The image acquisition device is a device that can acquire an image of asphalt. For example, the image acquisition device can be a digital camera or an analog camera, etc., but not limited to this.

[0077] In order to better understand the regenerated asphalt concrete production control method provided in the embodiment of the present application, the specific implementation process of the regenerated asphalt concrete production control method provided in the embodiment of the present application is exemplarily introduced below.

[0080] It is understood that the way to obtain the mixing information may be to receive data transmitted by the user, or to obtain the area where the recycled asphalt concrete needs to be used and the performance indicators that the produced recycled asphalt concrete needs to achieve, etc., but is not limited thereto. Obtaining the mixing information including the new asphalt quality information of the new asphalt required for producing the recycled asphalt concrete and the old asphalt quality information of the old asphalt can avoid the waste of resources caused by the production of too much recycled asphalt concrete, and provide a basis for subsequent steps.

[0081] In one possible implementation, see Figure 2 , S100, obtain mixing information, including:

[0082] S110, obtaining target area information; wherein the target area information includes paving area information, paving thickness information, mixture density information and surface layer compaction information.

[0083] It is understood that the target area information can be obtained by receiving data transmitted by the user or analyzing images of the area where the recycled asphalt concrete is required, but is not limited thereto. Obtaining the target area information including paving area information, paving thickness information, mixture density information and surface compaction information can provide a basis for calculating the weight of the recycled asphalt concrete to be produced, thereby avoiding the production of too much recycled asphalt concrete and causing waste of resources.

[0084] S120, obtaining processing and production information; wherein the processing and production information includes old asphalt content information and asphalt-to-stone ratio information.

[0085] It is understood that the processing and production information can be obtained by receiving data transmitted by the user, or by searching the application area of ​​the produced recycled asphalt concrete in the database, etc., but is not limited thereto. Obtaining the processing and production information including the old asphalt content information and the asphalt-stone ratio information can provide a reference for controlling the quality of the produced recycled asphalt concrete.

[0086] S130, obtaining mixing information based on the target area information and the processing production information.

[0087] It can be understood that the method of obtaining the mixing information based on the target area information and the processing and production information can be to receive the new asphalt quality information and the old asphalt quality information transmitted by the user after calculation based on the target area information, or to obtain the total mass of the mixture by multiplying the paving area by the paving thickness, the mixture density and the surface compaction degree, and then divide the total mass of the mixture by 1 and add the sum of the asphalt-stone ratio to obtain the total mass of the aggregate, and then confirm the new asphalt mass value obtained by multiplying the total mass of the aggregate by the asphalt-stone ratio as the new asphalt mass information, and then multiply the total mass of the aggregate by the old asphalt content and then by the asphalt-stone ratio to obtain the old asphalt mass value as the old asphalt mass information, etc., but not limited to this. Obtaining the mixing information based on the target area information and the processing and production information can avoid the production of too much recycled asphalt concrete, thereby causing waste of resources, and provide a basis for subsequent steps.

[0088] For example, assume that the paving area S = 1000 m2, the paving thickness h = 60 mm (converted to 0.06 m), and the mixture density ρ = 2.592 t / m 3 , surface compaction degree C = 98%, oil-stone ratio R = 5%, old asphalt content P = 30%, then the total mass of the mixture (M) = S × h × ρ × C = 1000 × 0.06 × 2.592 × 0.98 = 152.41t, the total mass of aggregate (A) = M / (1+R) = 152.41 / (1+0.05) = 145.15t, the mass of new asphalt (N) = R × A = 0.05 × 145.15 = 7.26t, the mass of old asphalt (I) = M × P × R = 152.41 × 0.3 × 0.05 = 2.29t.

[0090] It can be understood that the method of obtaining the mixing state information based on the mixing information and the mixing equipment information can be to determine the distribution of the new asphalt and the old asphalt reflected by the mixing information in the mixing equipment reflected by the mixing equipment information, or to divide the mixing equipment reflected by the mixing equipment information into multiple areas, and respectively determine the distribution state of the new asphalt and the old asphalt reflected by the mixing information in each area, but is not limited thereto. The mixing state information reflecting the mixing state of the new asphalt and the old asphalt in the mixing equipment obtained based on the mixing information and the mixing equipment information can determine whether the mixing of the new asphalt and the old asphalt is uniform, and provide a basis for controlling the mixing method of the mixing equipment.

[0091] In one possible implementation, see Figure 3 , S200, obtaining mixing state information based on mixing information and mixing equipment information, including:

[0092] S210, determining a mixing ratio based on the mixing information; wherein the mixing ratio is the ratio of the mass value reflected by the new asphalt mass information in the mixing information to the mass value reflected by the old asphalt mass information in the mixing information.

[0093] It is understood that the mixing ratio can be determined based on the mixing information by receiving data transmitted by the user, or by dividing the new asphalt mass by the old asphalt mass, etc., but is not limited thereto. Determining the mixing ratio based on the mixing information can provide a basis for subsequent steps.

[0094] For example, assuming that the mass of new asphalt is 7.26 tons and the mass of old asphalt is 2.29 tons, the mixing ratio = 7.26 / 2.29 = 3.17.

[0095] S220, controlling the conveying equipment to convey new asphalt having a mass value reflected by the new asphalt quality information and old asphalt having a mass value reflected by the old asphalt quality information into the mixing equipment, and making the ratio of new asphalt and old asphalt conveyed by the conveying equipment to the mixing equipment in the same time period equal to the mixing ratio.

[0096] It is understood that the conveying equipment can be an asphalt conveying pipeline, an asphalt station belt, etc., but is not limited thereto. Making the ratio of new asphalt and old asphalt delivered by the conveying equipment to the mixing equipment equal to the mixing ratio in the same time period can make the distribution of new asphalt and old asphalt more uniform and facilitate the subsequent steps.

[0098] It can be understood that controlling the heating device of the mixing equipment to heat the mixture formed by the new asphalt and old asphalt transported to the mixing equipment while controlling the stirring device of the mixing equipment to stir the mixture at a preset speed can make the new asphalt and the old asphalt better mixed together.

[0100] It can be understood that the method of obtaining the mixing state information based on the mixing ratio and the mixing equipment information can be to determine whether the distribution ratio of new asphalt and old asphalt in the mixing equipment reflected by the mixing equipment information on a horizontal cross section is equal to the value reflected by the mixing ratio, or to divide the mixing equipment reflected by the mixing equipment information into multiple areas, and respectively determine whether the distribution ratio of new asphalt and old asphalt in each area is between the two values ​​obtained by adding 0.2 and subtracting 0.2 from the value reflected by the mixing ratio, etc., but is not limited to this. Obtaining the mixing state information based on the mixing ratio and the mixing equipment information can ensure that the obtained mixing state information conforms to the production situation of recycled asphalt concrete, ensure the reliability of the mixing state information, and provide a basis for subsequent steps.

[0102] S241, obtaining a mixing height; wherein the mixing height reflects a height value of the mixed material in the mixing equipment reflected by the mixing equipment information.

[0103] It is understood that the mixing height can be obtained by receiving data transmitted by the user, or by receiving height data transmitted after a height measuring device measures the height of a mixing barrel of a mixing device, etc., but is not limited thereto. Obtaining the mixing height can provide a basis for subsequent steps.

One mixing area information corresponds to one mixing area, and the mixing area information includes information reflecting the distribution state of the mixture in the corresponding mixing area in the mixing equipment, and n is a positive integer, n≥2.

[0105] It is understood that n can be a preset value of 5, or a positive integer input by the user can be confirmed as n, etc., but is not limited thereto. Dividing the mixture into n areas evenly along the height direction of the mixing equipment and obtaining information of n mixing areas can respectively determine the mixing state of the mixture in each area of ​​the mixing equipment, avoid the situation of uneven mixing of new asphalt and old asphalt, and provide a basis for subsequent steps.

[0106] Exemplarily, assuming that the mixing height=5m, n=5, then the height of the mixing area corresponding to each mixing area information=5 / 5=1m.

[0107] S243, obtaining mixing state information based on the mixing ratio and multiple mixing area information; wherein the mixing area information includes physical characteristic information reflecting the mixed material in the mixing area.

[0108] It can be understood that the way to obtain the mixing state information based on multiple mixing area information can be to obtain an image of the mixing area corresponding to each mixing area information, and obtain it by judging the distribution of new asphalt and old asphalt on the image, or to obtain the weight of the mixture in the mixing area corresponding to each mixing area information, and obtain it by mass weight whether the new asphalt and old asphalt in the mixing area are mixed uniformly, etc., but not limited to this. The mixing state information including the physical characteristic information reflecting the mixture in the mixing area obtained based on multiple mixing area information can provide a basis for subsequent steps.

[0109] In one possible implementation, see Figure 5 , S243, obtaining mixing state information based on the mixing ratio and the multiple mixing area information, including:

[0110] S2431, control the image acquisition device to photograph the mixed materials in the mixing equipment corresponding to each mixing area in the multiple mixing area information along the diameter direction of the mixing equipment to obtain multiple area images; wherein each area image corresponds to a mixing area, and the area image is an image of the corresponding mixing area.

[0111] It can be understood that the image acquisition device is a device capable of acquiring asphalt images, for example, the image acquisition device can be a digital camera or an analog camera, etc., but is not limited thereto. Controlling the image acquisition device to photograph each mixing area along the diameter direction of the mixing equipment to obtain multiple area images can provide a basis for analyzing the distribution of new asphalt and old asphalt.

[0112] S2432, obtaining mixture distribution information based on the mixture ratio analysis area image; wherein the mixture distribution information corresponds to the mixture area, and the mixture distribution information reflects the distribution of new asphalt and old asphalt in the corresponding mixture area.

[0113] It can be understood that the method of analyzing the regional image to obtain the mixture distribution information can be to analyze the distribution of new asphalt and old asphalt in the regional image through an image processing model, or to receive data transmitted after manually analyzing the distribution of new asphalt and old asphalt in the regional image, etc., but it is not limited to this. Analyzing the regional image to obtain the mixture distribution information can ensure the reliability of the mixture distribution information and provide a basis for subsequent steps.

[0114] In one possible implementation, see Figure 6 , S2432, obtaining mixture distribution information based on the mixture ratio analysis region image, including:

[0115] S24321, input the regional image into the distribution recognition model to obtain the new and old distribution images; wherein the distribution recognition model is a data model obtained through machine learning, and the new and old distribution images include the input regional image and the new asphalt distribution contour and the old asphalt distribution contour annotated on the input regional image.

[0116] It can be understood that the distribution recognition model is obtained through machine learning training using multiple sets of data, and the multiple sets of data include the first type of data and the second type of data. Each set of data in the first type of data includes: at least one regional image, the distribution profile of new asphalt and the distribution profile of old asphalt in the regional image analyzed and identified manually, and each set of data in the second type of data includes: regional images that do not include new asphalt and labels that manually identify that the image does not include new asphalt, and regional images that do not include old asphalt and labels that manually identify that the image does not include old asphalt. Compared with manual judgment, the new and old distribution images obtained through the distribution recognition model can be more accurate and efficient, thereby improving processing efficiency.

[0117] S24322, respectively obtain the new asphalt area pixel value and the old asphalt area pixel value of the new and old distribution images; wherein the new asphalt area pixel value is the value obtained by adding the pixel values ​​occupied by all new asphalt distribution contours, and the old asphalt area pixel value is the value obtained by adding the pixel values ​​occupied by all old asphalt distribution contours.

[0118] It can be understood that the method of obtaining the new asphalt area pixel value and the old asphalt area pixel value of the new and old distribution images can be to receive the data annotated by the user on the new and old distribution images, or to calculate the pixels occupied by the new asphalt distribution contour and the pixels occupied by the old asphalt distribution contour on the new and old distribution images, but is not limited to this. Obtaining the new asphalt area pixel value and the old asphalt area pixel value of the new and old distribution images can provide a basis for subsequent steps.

[0119] For example, assuming that there are 4 new asphalt distribution contours on the new and old distribution images, and the pixel points occupied by each new asphalt distribution contour are 20, 30, 40, and 50 respectively, and there are 3 old asphalt distribution contours, and the pixel points occupied by each old asphalt distribution contour are 10, 20, and 30 respectively, then the new asphalt area pixel value = 20+30+40+50 = 140 pixels, and the old asphalt area pixel value = 10+20+30 = 60 pixels.

[0120] S24323, determine whether the ratio of the new asphalt area pixel value to the old asphalt area pixel value is within a preset ratio range; wherein the preset ratio range is the numerical interval between the two values ​​obtained by adding 0.2 and subtracting 0.2 respectively to the value reflected by the mixture ratio.

[0121] It can be understood that judging whether the ratio of the new asphalt area pixel value to the old asphalt area pixel value is within a preset ratio range is to judge whether the new asphalt and the old asphalt are evenly distributed.

[0122] For example, assuming that the new asphalt area pixel value is 140 pixels, the old asphalt area pixel value is 60 pixels, and the value reflected by the mixing ratio is 3.17, then the ratio of the new asphalt area pixel value to the old asphalt area pixel value = 140 / 60 = 2.33, and the preset ratio range is (3.17-0.2, 3.17+0.2) = (2.97, 3.37).

[0123] S24324, if the ratio of the new asphalt area pixel value to the old asphalt area pixel value is within a preset ratio range, then the mixture distribution information reflecting that the new asphalt and the old asphalt are evenly distributed in the mixture area corresponding to the input region image is obtained.

[0124] It can be understood that if the ratio of the new asphalt area pixel value to the old asphalt area pixel value is within a preset ratio range, it means that the new asphalt and the old asphalt are evenly distributed.

[0125] S24325, if the ratio of the new asphalt area pixel value to the old asphalt area pixel value is less than the minimum value within the preset ratio range, the mixture distribution information reflecting the excessive old asphalt content in the mixture area corresponding to the input area image is obtained.

[0126] It can be understood that if the ratio of the new asphalt area pixel value to the old asphalt area pixel value is less than the minimum value within the preset ratio range, it means that the content of new asphalt in the mixing area is less and the content of old asphalt is more.

[0127] For example, assuming the preset ratio range is (2.97, 3.37), the new asphalt area pixel value is 140 pixels, and the old asphalt area pixel value is 100 pixels, then the ratio of the new asphalt area pixel value to the old asphalt area pixel value = 140 / 100 = 1.4, 1.4 < 2.97.

[0128] S24326, if the ratio of the new asphalt area pixel value to the old asphalt area pixel value is greater than the maximum value within the preset ratio range, the mixture distribution information reflecting the excessive new asphalt content in the mixture area corresponding to the input area image is obtained.

[0129] It can be understood that if the ratio of the new asphalt area pixel value to the old asphalt area pixel value is greater than the maximum value within the preset ratio range, it means that the content of old asphalt in the mixing area is less and the content of new asphalt is more.

[0130] For example, assuming the preset ratio range is (2.97, 3.37), the new asphalt area pixel value is 240 pixels, and the old asphalt area pixel value is 60 pixels, then the ratio of the new asphalt area pixel value to the old asphalt area pixel value = 240 / 60 = 4, 4>2.97.

[0131] S2433, confirming all the mixture distribution information obtained after all the regional image analyses are completed as mixture state information.

[0132] It can be understood that confirming all the mixture distribution information obtained after all the regional image analyses are completed as the mixture state information can ensure the reliability of the mixture state information and provide a basis for subsequent steps.

[0133] S300, controlling the mixing equipment to produce recycled asphalt concrete based on the mixing state information.

[0134] It can be understood that controlling the mixing equipment to produce recycled asphalt concrete based on the mixing state information can avoid the problem of uneven mixing of old asphalt and new asphalt.

[0135] In one possible implementation, see Figure 7 , S300, controls the mixing equipment to produce recycled asphalt concrete based on the mixing state information, including:

[0136] S310, obtaining a control scheme based on the mixing state information; wherein the control scheme reflects the mixing method of the mixing equipment for the new asphalt and the old asphalt in the mixing area.

[0137] It can be understood that the control scheme based on the mixing state information can be obtained by judging the mixing state of new asphalt and old asphalt in each mixing area reflected by the mixing state information, or by receiving data transmitted by the user after the mixing state of new asphalt and old asphalt in each mixing area reflected by the mixing state information, but is not limited thereto. Obtaining the control scheme based on the mixing state information can ensure the reliability of the control scheme and provide a basis for determining the working mode of the stirring device of the mixing equipment.

[0138] In one possible implementation, see Figure 8 , S310, obtaining a control scheme based on the mixing state information, including:

[0139] S311, if the mixing status information contains mixing distribution information reflecting that the new asphalt and the old asphalt are evenly distributed in the mixing area, a sub-control scheme is obtained which is characterized by controlling the heating device to maintain the temperature in the mixing area corresponding to the mixing distribution information reflecting that the new asphalt and the old asphalt are evenly distributed in the mixing area, and controlling the stirring mechanism of the stirring device to maintain the rotation speed in the mixing area.

[0140] It can be understood that if the mixing state information contains mixing distribution information reflecting the uniform distribution of new asphalt and old asphalt in the mixing area, it means that there is no need to change the state of the area, and the rotation speed of the stirring device in the area and the temperature of the area can be maintained as they are.

[0141] S312, if there is mixing distribution information reflecting that the old asphalt content in the mixing area exceeds the standard in the mixing status information, a sub-control scheme is obtained that characterizes controlling the heating device to increase the temperature in the mixing area corresponding to the mixing distribution information reflecting that the old asphalt content in the mixing area exceeds the standard by m degrees, and controlling the stirring device to increase the rotation speed of the stirring mechanism located in the mixing area by n revolutions; wherein m and n are both positive numbers.

[0142] It is understood that the value of m can be set as needed, for example, it can be 15, 20, etc., but not limited to this. The value of n can be set as needed, for example, it can be 8, 10, etc., but not limited to this. If there is mixing distribution information reflecting that the old asphalt content in the mixing area exceeds the standard in the mixing state information, increasing the speed of the stirring device in the area by n revolutions and increasing the speed of the area by m can accelerate the change of the distribution of new asphalt and old asphalt in the area, and because the density and mass of the old asphalt are greater than the new asphalt of the same volume, the old asphalt in the area can be moved to other areas faster under the action of centrifugal force.

[0143] S313, if the mixing state information contains mixing distribution information reflecting that the new asphalt content in the mixing area exceeds the standard, a sub-control scheme for the mixing area corresponding to the mixing distribution information reflecting that the new asphalt content exceeds the standard is obtained based on the control confirmation method.

[0144] It can be understood that the sub-control scheme for the mixing area corresponding to the mixing distribution information reflecting the new asphalt content exceeding the standard can be obtained based on the control confirmation method by judging the mixing distribution information corresponding to other mixing areas adjacent to the mixing area corresponding to the mixing distribution information reflecting the new asphalt content exceeding the standard, or by receiving data transmitted by the user, etc., but is not limited thereto. The sub-control scheme for the mixing area corresponding to the mixing distribution information reflecting the new asphalt content exceeding the standard can ensure the reliability of the obtained sub-control scheme based on the control confirmation method.

[0145] In one possible implementation, see Fig. 9 In step S313, a sub-control scheme for the mixing area corresponding to the mixing distribution information reflecting the excessive new asphalt content is obtained based on the control confirmation method, including:

[0146] S3131, determine whether the mixing area corresponding to the mixing distribution information reflecting that the new asphalt content exceeds the standard has an adjacent mixing area whose corresponding mixing distribution information reflects that the old asphalt content exceeds the standard.

[0147] It can be understood that the method of judging whether the mixing area corresponding to the mixing distribution information reflecting the excessive new asphalt content has an adjacent mixing area corresponding to the mixing distribution information reflecting the excessive old asphalt content can be judging whether the mixing distribution information corresponding to the adjacent mixing area reflects the excessive old asphalt content, or can be receiving data transmitted after the user observes the mixing distribution information corresponding to the adjacent mixing area, etc., but is not limited thereto. Judging whether the mixing area corresponding to the mixing distribution information reflecting the excessive new asphalt content has an adjacent mixing area corresponding to the mixing distribution information reflecting the excessive old asphalt content can provide a basis for subsequent steps.

[0148] S3132, if the mixing area corresponding to the mixing distribution information reflecting the excessive new asphalt content has an adjacent mixing area corresponding to the mixing distribution information reflecting the excessive old asphalt content, then a sub-control scheme is obtained which characterizes controlling the heating device to reduce the temperature of the mixing area corresponding to the mixing distribution information reflecting the excessive new asphalt content by i degrees, and controlling the stirring device to reduce the rotation speed of the stirring mechanism located in the mixing area by j revolutions; wherein i and j are both positive numbers.

[0149] It can be understood that the value of i can be set as needed, for example, it can be 5, 10, etc., but not limited to this. The value of j can be set as needed, for example, it can be 5, 7, etc., but not limited to this. If the mixing area corresponding to the mixing distribution information reflecting the excessive new asphalt content has an adjacent mixing area corresponding to the mixing distribution information reflecting the excessive old asphalt content, then the old asphalt representing this area will move to the mixing area adjacent to this area. By controlling the heating device to reduce the temperature of the mixing area corresponding to the mixing distribution information reflecting the excessive new asphalt content by i degrees, and controlling the stirring device to reduce the speed of the stirring mechanism located in the mixing area by j revolutions, the mixing area corresponding to the mixing distribution information reflecting the excessive new asphalt content can better receive the old asphalt transported by the adjacent mixing area reflecting the excessive old asphalt content, thereby correspondingly reducing the new asphalt content in the mixing area reflecting the excessive new asphalt content.

[0150] S3133, if the mixing area corresponding to the mixing distribution information reflecting the excessive new asphalt content does not have an adjacent mixing area corresponding to the mixing distribution information reflecting the excessive old asphalt content, then a sub-control scheme is obtained, which is characterized by controlling the heating device to increase the temperature of the mixing area corresponding to the mixing distribution information reflecting the excessive new asphalt content by a degree, and controlling the stirring device to increase the rotation speed of the stirring mechanism located in the mixing area by b revolutions; wherein a and b are both positive numbers and a<m, b<n.

[0151] It can be understood that the value of a can be set as needed, for example, it can be 5, 10, etc., but not limited to this. The value of b can be set as needed, for example, it can be 5, 7, etc., but not limited to this. If the mixing area corresponding to the mixing distribution information reflecting the excessive content of new asphalt does not have an adjacent mixing area corresponding to the mixing distribution information reflecting the excessive content of old asphalt, then the heating device increases the temperature of the mixing area corresponding to the mixing distribution information of the excessive content of new asphalt by a degree, and controls the stirring device to increase the rotation speed of the stirring mechanism in the mixing area by b revolutions to accelerate the flow of new and old asphalt in the area. By adding the restrictions of a<m, b<n, the flow velocity of the mixture in the area can be made smaller than the flow velocity of the mixture in the mixing area with excessive content of old asphalt, and when the old asphalt flows into the mixing area with excessive content of new asphalt, it can stay in the area for a longer time.

[0152] S314: confirm all sub-control schemes as control schemes.

[0153] It can be understood that confirming all sub-control schemes as a control scheme can ensure the integrity and reliability of the control scheme.

[0154] S320, controlling the mixing equipment to produce recycled asphalt concrete based on the control scheme.

[0155] It can be understood that controlling the production of recycled asphalt concrete by mixing equipment based on the control scheme can make the distribution of new asphalt and old asphalt uniform, avoiding the problem of uneven mixing of recycled old asphalt and new asphalt, resulting in a decrease in the bearing capacity of the road surface and thus a decrease in the service life of the road surface.
