Description

Technical Field

[0001] The invention relates to the technical field of pipe pile mixers, and in particular to a concrete twin batching method and system for a pipe pile mixer. Background Art

[0002] In the pipe pile industry, the mixer is one of the main equipment for pipe pile production. The conveyor belt of the sand and gravel yard transports sand and mixed materials to the silo of the mixing plant, cement and ground sand are transported to the solid silo of the mixing plant through the automobile air pump, and water and water reducing agent are transported to the water pool or (tank) of the mixing plant through the water pump. After the reserves of these raw materials are available, the mixer completes the batching and mixing of various types of pipe piles according to the production plan; the raw materials are transported to the mixer according to the formula ratio, and after a certain mixing process, the concrete is formed and then flows into other procedures for pipe pile production. Among them, various raw materials are batched according to the ratio per cubic meter, and the batching ratio is implemented through the program (in kilograms). The kilograms and the program are solidified in the program according to various pile types. When producing different pile types, you only need to select the pile type to automatically complete the batching (i.e. feeding) mixing work.

[0003] However, the above-mentioned technical means are currently unable to analyze and diagnose the quality problems of various raw materials themselves, because the quality defects of raw materials will lead to frequent quality problems of batch products, resulting in widespread losses of various raw materials, labor cost losses, customer compensation losses and reduced reputation of corporate product quality. For example, sand often has excessive water content, and stone often contains mud (sand) and uneven particle sizes. The quality problems of the two main raw materials will directly lead to the internal kilograms of batching data of the original curing program being too dry or too thin during the process batching.

[0004] To address the above problems, currently, the mixing process quality (workability) of concrete is checked manually from the observation area of ​​the mixer, and then various required raw materials are added by hand after empirical analysis. However, this manual analysis process takes a long time; after adding the raw materials, it is easy to cause uneven mixing of the added raw materials due to insufficient mixing time. For example, uneven mixing of sand, stone and cement will directly affect the quality of the concrete. At the same time, manual addition of raw materials is prone to misjudgment due to human factors, that is, the addition amount (kg) of different raw materials cannot be accurately controlled according to the quality of the concrete, and adding too much or too little material will also cause quality defects of the concrete. Summary of the invention

[0010] As an improvement to the above solution, the preset material addition amount is a preset percentage of the initial material addition amount.

[0011] The present invention also provides a concrete twin batching system for a pipe pile mixer, comprising an image sensor, a switch actuator and a batching controller, wherein a plurality of the image sensors are respectively arranged at intervals on the observation area of ​​the mixer, the switch actuator is arranged at the discharge port of the hopper, and the image sensor and the switch actuator are arranged in a one-to-one correspondence; the batching controller is respectively connected to the image sensor and the switch actuator, and the batching controller comprises: an acquisition processing module, used to acquire a plurality of stirring images of the mixer after initial batching, wherein the plurality of stirring images include image data collected at different positions of the observation area, the stirring images at different positions respectively correspond to preset material comparison images in a one-to-one manner, and each of the material comparison images has different material properties; an image processing module, used to perform image comparison analysis processing on each stirring image and its corresponding material comparison image to obtain a corresponding material image processing result; a material adding processing module, used to determine whether the material image processing result is a preset material adding result value, and when it is determined to be yes, perform a corresponding preset material adding operation according to the material property of the material image processing result; a stirring processing module, used to control the mixer to stop working when the stirring time reaches a preset end time.

[0023] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, a specific embodiment of the present invention provides a concrete twin batching method for a pipe pile mixer, comprising:

[0025] S101, obtaining a plurality of stirring images of a mixer after initial batching, wherein the plurality of stirring images include image data collected at different positions of an observation area, the stirring images at different positions correspond one-to-one to preset material comparison images, and each of the material comparison images has different material properties;

[0026] It should be noted that the plurality of image sensors are arranged at intervals on the observation area of ​​the mixer, the switch actuator is arranged at the discharge port of the hopper, and the image sensors and the switch actuators are arranged one by one. The mixing image at each position corresponds to a material comparison image with different material properties, so as to perform a special concrete defect type detection on the material corresponding to the material property and realize the material adding work through the corresponding switch actuator.

[0027] Specifically, the step of acquiring a plurality of stirring images of the mixer after initial batching includes:

[0028] Step 1, performing initial batching on the mixer;

[0029] It should be noted that the corresponding initial batching ratio is adjusted according to the pile type requirements, so as to add the initial material addition amount of various materials to the mixer to achieve the initial batching work. For example, in this embodiment, materials such as sand, gravel, cement, water reducing agent, water and ground sand are added to the mixer to facilitate subsequent mixing into the required concrete.

[0030] Step 2: When the initial batching is completed, the mixer is controlled to perform the stirring operation and perform image pre-capture timing;

[0031] It should be noted that when the initial batching work is completed, the mixer stirs the added initial materials and the stirring time is set.

[0032] Step 3: determine whether the image pre-capture time reaches the preset image capture time, and if it is determined to be yes, obtain multiple stirring images of the blender.

[0033] It should be noted that when the image pre-capture time reaches the preset image capture time, the image capture work is performed, so as to perform image capture when the concrete is initially mixed and formed, realize quality defect detection and improve detection accuracy, avoid detection before the concrete is initially mixed and formed, thereby reducing detection accuracy, and avoid uneven mixing of various materials and failure of concrete to form when the concrete is tested and added after transitional forming due to insufficient mixing time, thereby affecting the quality of the concrete. Among them, the preset image capture time is preferably 1 minute, but it is not limited to this and can be adjusted according to actual needs.

[0034] Preferably, in this embodiment, mixing images collected at four different positions are obtained to detect concrete defect types corresponding to four materials (such as sand, stone, cement and water, whose material properties are sand properties, stone properties, cement properties and water properties) and implement the material adding work through the corresponding switch execution device. The corresponding concrete defect type detection is performed on the mixing conditions at different positions to ensure that the overall quality of the concrete meets the requirements.

[0035] S102, performing image comparison and analysis processing on each stirring image and its corresponding material comparison image to obtain a corresponding material image processing result;

[0036] Specifically, the material comparison image includes an OK material image and an NG material image, and the step of performing image comparison analysis on each stirring image and its corresponding material comparison image to obtain a corresponding material image processing result includes:

[0037] Step 1, performing image similarity analysis on the stirring image, the OK material image and the NG material image respectively;

[0038] Step 2: When the stirring image is similar to the OK material image, it indicates that there is no defect in the quality of the concrete, and an OK execution value is output; when the stirring image is similar to the NG material image, it indicates that there is a defect in the quality of the concrete and material addition is required, and an NG execution value and its material properties are output.

[0039] It should be noted that by performing image similarity analysis on each stirring image and its corresponding OK material image and NG material image, quality defect detection of the corresponding material can be achieved. When the stirring image is close to or similar to the OK material image, it means that the quality defect type of this concrete does not exist, and an OK execution value is output; when the stirring image is close to or similar to the NG material image, it means that the quality defect type of this concrete exists, and an NG execution value is output, and subsequent addition of this material is required to improve the quality problems of the concrete during the mixing process.

[0040] For example, in the material comparison image of sand material, when the corresponding mixing image is subjected to image similarity analysis with its corresponding OK material image and NG material image, if the mixing image is similar to the NG material image, it indicates that the current concrete has quality defects such as too much gravel and too little sand, and sand addition is required; otherwise, if it is similar to the OK material image, it indicates that there are no quality defects, and the required production quality requirements are met.

[0041] For example, for the material comparison image of stone material, when the corresponding mixing image is analyzed for image similarity with its corresponding OK material image and NG material image, if the mixing image is similar to the NG material image, it means that the current concrete has the quality defect of less stone and more sand, and it is necessary to add stone, otherwise it is the same as above. For example, for the material comparison image of cement material, when the corresponding mixing image is analyzed for image similarity with its corresponding OK material image and NG material image, if the mixing image is similar to the NG material image, it means that the current concrete has the quality defect of being too thin and less cement, and it is necessary to add cement, otherwise it is the same as above. For example, for the material comparison image of water material, when the corresponding mixing image is analyzed for image similarity with its corresponding OK material image and NG material image, if the mixing image is similar to the NG material image, it means that the current concrete has the quality defect of being too dry, hard and less water, and it is necessary to add water, otherwise it is the same as above. If multiple defects occur at the same time, the filling work of the corresponding materials is implemented according to the defect detection results. Generally, the multiple defects with a higher probability are the two defects that need to add cement and stone or cement and sand.

[0042] It should be supplemented that the present invention uses the existing similarity analysis processing technology between images to perform similarity analysis processing between the stirring image and the material comparison image.

[0043] S103, determining whether the material image processing result is a preset material adding result value, and if it is determined to be yes, performing a corresponding preset material adding operation according to the material attribute of the material image processing result;

[0044] It should be noted that when the material image processing result is the preset material adding result value (i.e. the preset NG execution value), that is, the NG execution value of the material image processing result is the same as the preset material adding result value, it indicates that there is a concrete quality defect type of the corresponding material. At this time, the corresponding preset material addition work needs to be performed according to the material properties of the material image processing result.

[0045] Specifically, the step of performing corresponding preset material adding work according to the material attributes of the material image processing result includes:

[0046] Step 1: when adding material is required, the corresponding preset material addition amount and preset hopper discharge amount are obtained from the preset material data table according to the material properties, and the switch actuator of the corresponding hopper is controlled to open the discharge port according to the material properties, and the adding time is counted;

[0047] It should be noted that when adding material is required, the material to be added is determined according to the material properties, the corresponding preset material addition amount and preset hopper discharge amount are obtained in the preset material data table according to the determined material, and the switch actuator of the hopper used to store the material is controlled to open the discharge port according to the determined material to realize the material adding work, and then the adding time is counted. Among them, the switch actuators 2 corresponding to sand, gravel and cement are all cylinder switch actuators, which realize the opening and closing of the discharge port by pushing the sealing plate through the cylinder; the switch actuator corresponding to water is a solenoid valve, which realizes the opening and closing of the discharge port by switching the solenoid valve.

[0048] Step 2, calculating the material adding time according to the preset material adding amount and the preset hopper discharge amount;

[0049] It should be noted that the discharge amount of the hopper, that is, the discharge amount per unit time, can be known through the diameter of the discharge port of the hopper, so as to obtain the preset hopper discharge amount. The time required to discharge the preset material addition amount, that is, the material feeding time, can be calculated through the preset material addition amount and the preset hopper discharge amount. Among them, the preset material addition amount is a preset percentage of the initial material addition amount. In this embodiment, the preset percentage values ​​of sand, stone, cement and water are preferably 30%, that is, the preset material addition amount is 30% of the initial material addition amount, but it is not limited.

[0050] Step 3: When the feeding time reaches the material feeding time, the switch execution device is controlled to close the feeding port and stop the feeding work.

[0051] It should be noted that when the feeding time reaches the material feeding time, the preset material addition amount of the material has been completed. At this time, the switch actuator is controlled to close the feed port and stop the feeding work, thereby completing the material feeding work, improving the quality defects of the corresponding concrete, and improving the quality of the concrete. When adding sand, stone, cement or water, the preset material addition amount of the corresponding material is realized by controlling the corresponding switch actuator to open the feed port. For example, when the initial material addition amount of the sand material is 500KG, the preset material addition amount of the sand is 150KG.

[0052] S104: When the stirring time reaches a preset end time, the stirring machine is controlled to stop working.

[0053] It should be noted that when the mixing time reaches the preset end time, the mixer is controlled to stop working, at which time the mixer mixes the desired shaped concrete with high concrete quality. The preset end time is preferably 2 minutes, but is not limited thereto.

[0054] like Figure 2As shown, the present invention also provides a concrete twin batching system for a pipe pile mixer, comprising an image sensor 1, a switch actuator 2 and a batching controller 3, wherein a plurality of the image sensors 1 are arranged at intervals on the observation of the mixer, the switch actuator 2 is arranged at the discharge port of the hopper, and the image sensors 1 and the switch actuator 2 are arranged in a one-to-one correspondence;

[0055] The batching controller 3 is connected to the image sensor 1 and the switch actuator 2 respectively, and the batching controller 3 includes:

[0056] An acquisition processing module 31 is used to acquire a plurality of stirring images of the mixer after initial batching, wherein the plurality of stirring images include image data collected at different positions of the observation area, the stirring images at different positions correspond to preset material comparison images one by one, and each of the material comparison images has different material properties;

[0057] It should be noted that the plurality of image sensors 1 are arranged at intervals on the observation area of ​​the mixer, the switch actuator 2 is arranged at the discharge port of the hopper, and the image sensor 1 is arranged in one-to-one correspondence with the switch actuator 2. The mixing image at each position corresponds to a material comparison image with different material properties, so as to perform a special concrete defect type detection on the material corresponding to the material property and realize the material adding work through the corresponding switch actuator 2.

[0058] Specifically, Figure 3 As shown, the acquisition processing module 31 includes:

[0059] An initial batching unit 311 is used to perform initial batching on the mixer;

[0060] It should be noted that the corresponding initial batching ratio is adjusted according to the pile type requirements, so as to add the initial material addition amount of various materials to the mixer to achieve the initial batching work. For example, in this embodiment, materials such as sand, gravel, cement, water reducing agent, water and ground sand are added to the mixer to facilitate subsequent mixing into the required concrete.

[0061] A timing processing unit 312 is used to control the mixing operation of the mixer and perform image pre-capture timing when the initial batching operation is completed;

[0062] It should be noted that when the initial batching work is completed, the mixer stirs the added initial materials and the stirring time is set.

[0063] The acquisition processing unit 313 is used to determine whether the image pre-acquisition time reaches the preset image acquisition time, and if it is determined to be yes, acquire a plurality of stirring images of the blender.

[0064] It should be noted that when the image pre-capture time reaches the preset image capture time, the image capture work is performed, so as to perform image capture when the concrete is initially mixed and formed, realize quality defect detection and improve detection accuracy, avoid detection before the concrete is initially mixed and formed, thereby reducing detection accuracy, and avoid uneven mixing of various materials and failure of concrete to form when the concrete is tested and added after transitional forming due to insufficient mixing time, thereby affecting the quality of the concrete. Among them, the preset image capture time is preferably 1 minute, but it is not limited to this and can be adjusted according to actual needs.

[0065] Preferably, in this embodiment, mixing images collected at four different positions are obtained to detect concrete defect types corresponding to four materials (such as sand, stone, cement and water, whose material properties are sand properties, stone properties, cement properties and water properties) and implement the material adding work through the corresponding switch actuator 2. The corresponding concrete defect type detection is performed on the mixing conditions at different positions to ensure that the overall quality of the concrete meets the requirements.

[0066] An image processing module 32, used for performing image comparison and analysis processing on each stirring image and its corresponding material comparison image to obtain a corresponding material image processing result;

[0067] Specifically, Figure 4 As shown, the material comparison image includes an OK material image and an NG material image, and the image processing module 32 includes:

[0068] An image analysis unit 321 is used to perform image similarity analysis processing on the stirring image, the OK material image and the NG material image respectively;

[0069] The image similarity processing unit 322 is used to indicate that when the mixing image is similar to the OK material image, it indicates that there is no defect in the quality of the concrete and output an OK execution value; when the mixing image is similar to the NG material image, it indicates that there is a defect in the quality of the concrete and material addition is required, and output an NG execution value and its material properties.

[0070] It should be noted that by performing image similarity analysis on each stirring image and its corresponding OK material image and NG material image, quality defect detection of the corresponding material can be achieved. When the stirring image is close to or similar to the OK material image, it means that the quality defect type of this concrete does not exist, and an OK execution value is output; when the stirring image is close to or similar to the NG material image, it means that the quality defect type of this concrete exists, and an NG execution value is output, and subsequent addition of this material is required to improve the quality problems of the concrete during the mixing process.

[0071] For example, in the material comparison image of sand material, when the corresponding mixing image is subjected to image similarity analysis with its corresponding OK material image and NG material image, if the mixing image is similar to the NG material image, it indicates that the current concrete has quality defects such as too much gravel and too little sand, and sand addition is required; otherwise, if it is similar to the OK material image, it indicates that there are no quality defects, and the required production quality requirements are met.

[0072] For example, for the material comparison image of stone material, when the corresponding mixing image is analyzed for image similarity with its corresponding OK material image and NG material image, if the mixing image is similar to the NG material image, it means that the current concrete has the quality defect of less stone and more sand, and it is necessary to add stone, otherwise it is the same as above. For example, for the material comparison image of cement material, when the corresponding mixing image is analyzed for image similarity with its corresponding OK material image and NG material image, if the mixing image is similar to the NG material image, it means that the current concrete has the quality defect of being too thin and less cement, and it is necessary to add cement, otherwise it is the same as above. For example, for the material comparison image of water material, when the corresponding mixing image is analyzed for image similarity with its corresponding OK material image and NG material image, if the mixing image is similar to the NG material image, it means that the current concrete has the quality defect of being too dry, hard and less water, and it is necessary to add water, otherwise it is the same as above. If multiple defects occur at the same time, the filling work of the corresponding materials is implemented according to the defect detection results. Generally, the multiple defects with a higher probability are the two defects that need to add cement and stone or cement and sand.

[0073] It should be supplemented that the present invention uses the existing similarity analysis processing technology between images to perform similarity analysis processing between the stirring image and the material comparison image.

[0074] A material adding processing module 33 is used to determine whether the material image processing result is a preset material adding result value, and if it is determined to be yes, perform a corresponding preset material adding operation according to the material property of the material image processing result;

[0075] It should be noted that when the material image processing result is the preset material adding result value (i.e. the preset NG execution value), that is, the NG execution value of the material image processing result is the same as the preset material adding result value, it indicates that there is a concrete quality defect type of the corresponding material. At this time, the corresponding preset material addition work needs to be performed according to the material properties of the material image processing result.

[0076] Specifically, Figure 5 As shown, the material adding processing module 33 includes:

[0077] The material adding processing unit 331 is used to obtain the corresponding preset material addition amount and preset hopper discharge amount from the preset material data table according to the material properties when material adding is required, and control the switch execution device 2 of the corresponding hopper to open the discharge port according to the material properties, and count the material adding time;

[0078] It should be noted that when adding material is required, the material to be added is determined according to the material properties, and the corresponding preset material addition amount and preset hopper discharge amount are obtained in the preset material data table according to the determined material, and the switch actuator 2 of the hopper used to store the material is controlled to open the discharge port according to the determined material to realize the material adding work, and then the adding time is counted. Among them, the switch actuator 2 corresponding to sand, gravel and cement are all cylinder switch actuators, and the sealing plate is pushed by the cylinder to realize the opening and closing of the discharge port; the switch actuator corresponding to water is a solenoid valve, and the opening and closing of the discharge port is realized by the opening and closing of the solenoid valve.

[0079] A material adding calculation unit 332, used to calculate the material adding time according to a preset material adding amount and a preset hopper discharge amount;

[0080] It should be noted that the discharge amount of the hopper, that is, the discharge amount per unit time, can be known through the diameter of the discharge port of the hopper, so as to obtain the preset hopper discharge amount. The time required to discharge the preset material addition amount, that is, the material feeding time, can be calculated through the preset material addition amount and the preset hopper discharge amount. Among them, the preset material addition amount is a preset percentage of the initial material addition amount. In this embodiment, the preset percentage values ​​of sand, stone, cement and water are preferably 30%, that is, the preset material addition amount is 30% of the initial material addition amount, but it is not limited.

[0081] The material adding judgment processing unit 333 is used to control the switch execution device 2 to close the material discharge port and stop the material adding work when the material adding time reaches the material adding time.

[0082] It should be noted that when the feeding time reaches the material feeding time, the preset material addition amount of the material has been completed. At this time, the switch actuator 2 is controlled to close the feed port and stop the feeding work, thereby completing the material feeding work, improving the quality defects of the corresponding concrete, and improving the quality of the concrete. When adding sand or stone or cement or water, the corresponding switch actuator 2 is controlled to open the feed port to achieve the adding work of the preset material addition amount of the corresponding material. For example, when the initial material addition amount of the sand material is 500KG, the preset material addition amount of the sand is 150KG.

[0083] The stirring processing module 34 is used to control the stirrer to stop working when the stirring time reaches a preset end time.

[0084] It should be noted that when the mixing time reaches the preset end time, the mixer is controlled to stop working, at which time the mixer mixes the desired shaped concrete with high concrete quality. The preset end time is preferably 2 minutes, but is not limited thereto.

[0085] In summary, the present invention collects mixing images during the concrete mixing process and compares and analyzes them with the corresponding material comparison images to determine whether the quality of the current concrete has defects. If defects exist, the defect type can be determined by material properties and corresponding material addition work can be performed to improve the quality problems of the concrete during the mixing process, effectively avoid the occurrence of quality defects in concrete, improve the molding quality of concrete, and meet the needs of concrete production.

[0086] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
