Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to an intelligent proportioning, mixing and retesting system and method for water-brushed stone slurry. Background Art

[0002] With the acceleration of urbanization, the demand for the protection and restoration of historical buildings is growing. In the restoration and protection of traditional historical buildings, especially the restoration of water-brushed stone veneers, there are many challenges. Existing technical solutions often lack the emphasis on precise batching and post-construction quality re-inspection, resulting in a large difference between the restoration effect and the original building style. In addition, the preparation and re-inspection process of the sample is time-consuming and inefficient, the proportion data is not accurately recorded, there is a lack of effective machine learning algorithms to optimize the batching scheme, and the quantity control and anti-condensation measures of the water-brushed stone slurry are insufficient. These problems have seriously affected the construction quality and efficiency, and thus affected the progress and cost of the entire project.

[0003] Specifically, the existing technology has the following limitations in the field of restoration of water-brushed stone veneer of historical buildings:

[0004] 1. The traditional method of repairing water-brushed stone finishes often relies on the experience and intuition of construction workers to manually weigh the proportions of cement, stone and pigment when mixing ingredients. This operation method that relies on personal feelings lacks consistency and repeatability, and leads to insufficient precision in the proportion of raw materials. The quality re-inspection after construction is difficult to meet the expected standards, which affects the coordination of the appearance of the restored building and the historical style, resulting in differences in texture and durability between the restored wall and the original wall. For example, construction workers may add too much water based on their feelings, resulting in increased fluidity of the stone slurry, but this also makes the stone slurry prone to cracks and fall off after drying on the wall; other examples include errors in the color matching of cement walls, resulting in differences in warm and cold colors, making it impossible to achieve perfect repair and restoration.

[0005] 2. In traditional repair work, the recording of the proportion data of the ingredients often relies on manual records, lacking systematic and digital management, recording and analysis. Especially for the same construction object, if a repair project is completed by different workers at different times, each worker may adjust the proportion according to his own experience, resulting in differences in the final repair effect. This lack of standardization and data-driven methods limits the predictability and controllability of the repair work, and often lacks the proportion information of the past repair due to data loss, which leads to differences in the proportion information of the water-brushed stone slurry used in the second repair construction. In addition, due to the characteristics of the water-brushed stone slurry, it is necessary to apply it to the wall and wait until it dries before verifying the effect of the proportion. If a sample is used, it will take time and raw material costs; at the same time, since the water-brushed stone slurry has high requirements for the precision of the raw material proportion, the water-brushed stone slurry that is mixed and mixed by relying solely on the experience of the construction personnel in the existing technology is prone to errors in the color proportion after mixing. If the error is found after the wall is solidified and washed, it is not only necessary to knock it out and re-construct, which reduces the construction efficiency, but also difficult to determine the proportion adjustment direction and specific dosage calculation by naked eye.

[0006] 3. In the traditional preparation process of water-brushed stone veneer samples, construction workers must mix and balance the raw materials on site to produce water-brushed stone slurry for the samples. This step is dependent on the experience and skills of the construction workers and has certain uncertainties. In addition, after the water-brushed stone slurry used for sample production is mixed, it needs to be manually flushed before it is completely solidified to form the initial appearance of the sample. After the flushing step is completed, it is necessary to wait for the water-brushed stone slurry to solidify again. The whole process may take several days, which not only greatly prolongs the construction period, but also makes it difficult to guarantee the quality of the finished product due to the lack of standardized re-inspection. For conventional sample re-inspection, after the sample is made, it is usually necessary for multiple personnel to re-inspect to confirm whether the sample is consistent with the reference standard of the construction object. This re-inspection method mainly relies on visual observation and lacks accurate comparison tools and standardized re-inspection methods, resulting in a great deal of subjectivity in the re-inspection results, making it difficult to achieve precise deployment that is exactly the same as the reference of the construction object. When the subjective judgment sample is inconsistent with the reference standard of the construction object, the construction personnel are required to make repeated adjustments based on experience, which not only increases the workload, but may also lead to waste of raw materials and delays in construction progress. In addition, even if the sample is made, the re-inspection after construction is also faced with challenges. Traditional methods usually rely on the visual inspection of construction personnel, lack of professional re-inspection equipment and standardized re-inspection procedures. For example, the finish of the newly repaired construction object may have slight differences in color from the surrounding original finishes or reference finish photos, but this difference is difficult to be accurately identified without the assistance of professional equipment. This re-inspection method that relies on subjective judgment may lead to inconsistency in the quality of restoration, which in turn affects the overall beauty of the building and the inheritance of its historical value. Therefore, it is urgent to introduce more scientific and standardized sample preparation and post-construction re-inspection methods to improve construction efficiency and restoration quality.

[0007] Therefore, in order to better protect and inherit the unique features and cultural value of historical buildings, it is urgent to provide a more efficient, accurate and reliable solution for the proportioning, mixing and re-inspection of water-brushed stone slurry, so as to significantly improve the quality and efficiency of restoration work.

[0013] The second aspect of the present invention provides an intelligent proportioning, mixing and retesting method for water-brushed stone slurry, using any one of the above-mentioned intelligent proportioning, mixing and retesting systems for water-brushed stone slurry, comprising the following steps:

[0014] Input the name of the construction object, collect visual data of the construction object and intelligently identify it to obtain the initial ratio of water-brushed stone mortar; compare the name of the construction object and the initial ratio with the cloud database information, and determine the production procedure and the actual mixing ratio according to the comparison results; the production procedure includes the semi-automatic production procedure of the quick-setting sample and the automatic production procedure of the construction water-brushed stone mortar:

[0015] When the semi-automatic production program of the quick-setting sample is carried out, the initial mix ratio and the total amount of the sample are automatically input, and the amount of the quick-setting agent is automatically calculated and input according to the mud-stone ratio in the initial mix ratio, and the material is automatically discharged and mixed; the water-brushed stone slurry after mixing is discharged from the second slurry outlet valve and falls into the sample frame in the quick-setting sample production area to produce the quick-setting sample, and the visual data of the quick-setting sample product and the visual data of the construction object are collected for re-inspection, and the initial mix ratio is adjusted and re-assigned, until the initial mix ratio is used as the actual mixing ratio after the re-inspection is qualified, and the automatic production program of the water-brushed stone slurry for construction is switched;

[0016] When the automatic production program of water-brushed stone slurry is carried out, the actual mixing ratio is automatically input, the total amount required for construction is manually input, and the material is automatically discharged and mixed, and the actual amount of each raw material is simultaneously recorded; after the mixing is completed, the water-brushed stone slurry is discharged from the first slurry outlet valve and falls into the construction container for finishing construction; after the finishing construction is completed, the visual data of the finished finishing product and the visual data of the construction object are collected for re-inspection, and the data is uploaded to improve the cloud database information and for the training of the algorithm model for intelligent recognition;

[0017] During the automatic material discharge and mixing process, monitor the viscosity of the water-brushed stone slurry, continue stirring until the viscosity meets the requirements and then discharge the slurry through the corresponding slurry discharge valve.

[0019] As a preferred technical solution, the specific steps of determining the production procedure and the actual mixing ratio according to the comparison results include:

[0020] When there is no corresponding construction object name in the cloud database, a new file is created in the cloud database with the current construction object name, and the construction information of the current construction object is analyzed and stored in the new file, wherein the construction information includes visual data, initial mix ratio information and mix ratio record date, and a semi-automatic production program of a quick-setting sample is performed according to the initial mix ratio obtained by the analysis, and the quick-setting sample product obtained by the production is re-inspected and the initial mix ratio is re-adjusted and assigned until the re-inspection is qualified, and the initial mix ratio after the final adjustment and assignment when the re-inspection is qualified is used as the actual mixing ratio, and an automatic production program of water-brushed stone slurry for construction is performed;

At the same time, there is no need for experience in proportion identification and calculation for construction finishes, thus saving training costs and improving construction efficiency and quality. Accurate proportioning can be achieved and quality inspection after construction can meet higher standards, thereby better restoring and protecting the original appearance of historical buildings and ensuring the aesthetics and consistency of construction results.

[0030] (2) The intelligent proportioning, mixing and re-inspection system and method for water-brushed stone slurry of the present invention can effectively grasp the setting time of the water-brushed stone slurry under unit weight by combining the raw material proportion of the water-brushed stone slurry, the size of the sample frame and the calculated amount of accelerating setting agent, and on this basis achieve the stability of the finished product of the quick-setting sample, improve the controllability of the flushing operation, and at the same time provide a more stable comparison basis for the re-inspection of the quick-setting sample finished product. In addition, the rotational torque feedback data of the servo motor and further visual recognition can realize real-time monitoring of the viscosity of the water-brushed stone slurry during the mixing process, thereby ensuring the continuity of the construction process and the quality stability of each batch of water-brushed stone slurry, and ultimately achieving the purpose of improving construction efficiency and quality.

[0031] (3) The intelligent proportioning, mixing and re-inspection system and method for water-brushed stone slurry of the present invention can effectively improve construction efficiency and quality through intelligent analysis and management of cloud database. When the database lacks information on the corresponding construction object, the system can automatically create a new file and store the construction information, so as to ensure that each construction has a record to follow, and can perform quality control and raw material management through historical data; at the same time, when the corresponding construction object name exists in the cloud database, by confirming the consistency of the initial proportion and the historical proportion information, it can play a role in ensuring the continuity of construction and the stability of quality. When the initial proportion is consistent with the historical data, it can be directly used to ensure the consistency of construction in different time periods; when it is inconsistent, further analysis and adjustment are made to ensure the stability of construction quality.

[0032] (4) The intelligent proportioning, mixing and re-testing system and method for water-brushed stone slurry of the present invention can adapt to different construction conditions and requirements through flexible switching between the semi-automatic production program of the quick-setting sample and the automatic production program of the construction water-brushed stone slurry, thereby improving construction efficiency, reducing raw material waste, ensuring construction quality, and also reducing the workload of construction personnel. Specifically, the semi-automatic production program of quick-setting samples can realize the rapid production, accurate re-inspection and intelligent ratio adjustment of samples. By accelerating the production of finished samples in a short time and through stable re-inspection inspection methods and scientific algorithm adjustments, human errors can be reduced and the ratio can be optimized to the best state before construction, thereby improving construction quality, reducing raw material waste, and shortening the construction period; through the automatic production program of water-brushed stone slurry for construction, construction consistency can be ensured and production efficiency can be improved. The automatic production program can accurately produce water-brushed stone slurry for construction according to the actual mixing ratio that has been re-inspected, ensuring that each batch of water-brushed stone slurry meets the construction requirements, thereby improving production efficiency and the accuracy of raw material use. At the same time, through automated control of production, the uncertainty of manual operation can be reduced, labor intensity can be reduced, and the overall quality of construction can be improved.

Example 2

[0042] like Figure 2 As shown, this embodiment provides a method for an intelligent proportioning, mixing and retesting system for water-brushed stone slurry using embodiment 1, comprising the following steps:

[0043] First, input the name of the construction object, collect visual data of the construction object and intelligently identify it, and obtain the initial ratio of the water-brushed stone slurry. In this embodiment, image recognition technology is used to scan the reference surface of the construction object or the reference surface photo through the visual recognition unit, collect visual data of the water-brushed stone and cement in the object or photo, intelligently identify the type and dosage ratio of the raw materials, and obtain the initial ratio.

[0044] Then, the name of the construction object and the initial ratio obtained through collection and identification are compared with the cloud database information; the cloud database information includes the name of the construction object, visual data and the corresponding ratio information, and the ratio record date; then, the actual mixing ratio is determined according to the comparison result and switched to the corresponding production program, which includes the automatic production program for water-brushed stone slurry and the semi-automatic production program for quick-setting samples. Among them, the initial ratio and ratio information both include stone type, stone particle size, stone color, ratio between each stone, mud-stone ratio, and cement color pigment ratio.

[0045] (1) When there is no corresponding construction object name in the cloud database, a new file is created with the current construction object name, and the construction information of the current construction object is analyzed and stored in the new file. The construction information includes visual data, initial mix ratio information obtained through visual data and intelligent recognition, and mix ratio record date; then, a semi-automatic production procedure of a quick-setting sample is performed according to the initial mix ratio obtained through analysis, and the quick-setting sample product obtained is re-inspected and the initial mix ratio is readjusted and assigned until the re-inspection is qualified. The final adjusted initial mix ratio when the re-inspection is qualified is used as the actual mixing ratio, and an automatic production procedure of water-brushed stone slurry is performed for construction.

[0046] The semi-automatic production procedure of the quick-setting sample includes the following specific steps: automatically inputting the initial mix ratio and the total amount of the sample, automatically calculating and inputting the amount of the quick-setting agent according to the mud-stone ratio in the initial mix ratio, automatically discharging and mixing the materials, and simultaneously recording the actual amount of each raw material and the quick-setting agent added; in the process of automatic discharging and mixing, monitoring the viscosity, when the viscosity is qualified, automatically discharging the slurry through the second slurry outlet valve and transporting it to the sample production area to produce the quick-setting sample product. Specifically, the mixed water-brushed stone slurry is discharged from the second slurry outlet valve and falls into the sample frame in the quick-setting sample production area, and is flattened by using a pressing plate matched with the sample frame. When the flushing solidification conditions are reached, an alarm is triggered to remind and flushing operation is performed, and data acquisition is used. The intelligent recognition technology is integrated to collect visual data information of the quick-setting sample product obtained after solidification by flushing, and the visual data information of the quick-setting sample product is compared and re-inspected with the visual data of the construction object to evaluate the initial ratio and quality of the water-brushed stone slurry. If the visual data based on the quick-setting sample product is inconsistent with the visual data of the construction object, the error range is adjusted through the machine learning algorithm. Specifically, the initial ratio is adjusted and re-assigned through the machine learning algorithm until the visual data of the quick-setting sample product is consistent with the visual data of the construction object. The initial ratio after the final adjustment and assignment when the re-inspection is qualified is used as the actual mixing ratio, and the automatic production program of the water-brushed stone slurry for construction is switched.

[0047] In this embodiment, the flushing operation is performed manually. In addition, before the water-brushed stone slurry raw materials for the quick-setting sample are automatically discharged and mixed, it is detected and ensured that an empty sample frame has been installed and placed in the quick-setting sample production area. Specifically, a weight sensor for weighing the sample frame can be set at the sample frame to detect the weight of the sample frame before automatic discharge and mixing. When the weight of the sample frame is greater than the set empty sample frame weight value, an alarm will be triggered to prompt the construction personnel to replace the sample frame to ensure the smooth production of the quick-setting sample.

[0048] In this embodiment, the quick-setting agent is added after all the raw materials in the initial ratio are discharged, thereby realizing the rapid preparation of the quick-setting sample, shortening the production cycle of the quick-setting sample by accelerating the solidification process, speeding up the re-inspection, and improving the construction efficiency. The traditional sample production takes a long time, and in order to wait for the finished product of the sample to be completed and the finished product after completion, it needs to be manually confirmed by multiple personnel to see if it is qualified, which delays the progress of the construction; in this embodiment, the total amount of the sample is determined by the sample frame size of the quick-setting sample production area, and the size of the sample frame that can be detachably installed in the same mixer body is consistent. Therefore, according to the initial ratio information and the total amount of the sample determined based on the sample frame size of the quick-setting sample area and the addition of the quick-setting agent, the thickness of the quick-setting sample is unified, which can ensure that the required water-brushed stone sample thickness and stone exposed height can be quickly obtained according to the current ratio information and the total amount of the sample. At the same time, the stable sample results obtained allow more accurate quality monitoring through visual data collection. In other embodiments, by combining heating and light curing technology in the template making area to achieve rapid drying and solidification of the quick-setting template, the influence of environmental factors in the traditional template making process is avoided, the confirmation process of the proportion information of the water-brushed stone slurry used for construction is accelerated, and the construction efficiency is improved while ensuring the stability of the proportion quality of the water-brushed stone slurry.

[0049] (2) When the corresponding construction object name exists in the cloud database, confirm whether the initial mix ratio is consistent with the historical mix ratio information under the same construction object name in the cloud database. If they are consistent, the initial mix ratio is used as the actual mixing ratio to perform the automatic production procedure of water-brushed stone slurry for construction; if they are inconsistent, further confirm whether they are different areas to be constructed for the same construction object: when the areas to be constructed are the same, calibrate the initial mix ratio, reassign the calibrated mix ratio information to the initial mix ratio, and use the calibrated initial mix ratio as the actual mixing ratio to perform the automatic production procedure of water-brushed stone slurry for construction. At the same time, use the data collected during the calibration process for machine learning algorithm model training to enhance the intelligent recognition ability of the machine learning model; when the areas to be constructed are different, that is, the water-brushed stone facings of the same construction object have different ratios in different areas, at this time, create a sub-file under the current construction object name file, and re-check and adjust the actual mixing ratio through the semi-automatic production procedure of the above-mentioned quick-setting sample.

[0050] The automatic production procedure of the water-brushed stone slurry for construction includes the following steps: automatically input the actual mixing ratio, and after the construction personnel input the required total construction amount according to the actual construction situation, automatically discharge the materials and mix them, and simultaneously record the actual amount of each raw material added, so as to realize the automatic and accurate batching and discharging and automatic stirring and mixing of the water-brushed stone slurry; in the process of automatic discharge and mixing, the viscosity of the water-brushed stone slurry is monitored, and stirring is continued until the viscosity meets the requirements. When the viscosity is qualified, the slurry is automatically discharged through the first slurry discharge valve and transported to the construction container for finishing construction; specifically, the water-brushed stone slurry after mixing is discharged from the first slurry discharge valve, and falls into the construction container from the slurry discharge port after passing through the slurry discharge channel for finishing construction.

[0051] In actual work, since the repair demand of water-brushed stone finishes spans a large period of time, the cement color, stone color, and stone exposure degree required for the water-brushed stone finishes of the same construction object will often change after years of sun and wind. Therefore, during the correction process, the stone type, stone particle size, ratio between each stone, and mud-stone ratio in the initial ratio are adjusted to be consistent with the historical ratio information, and the stone color and cement color are re-proportioned; in this embodiment, in the case where the water-brushed stone finishes of the same construction object have the same ratio in different areas, by maintaining the consistency of the stable and unchanging parts in the ratio information of the same construction object, only the changed parts are adjusted, which saves the process of re-proportioning and sample making for each construction, and speeds up the construction progress and efficiency.

[0052] Finally, after the finishing construction is completed, the quality of the finished finishing products of the construction object is re-inspected through visual data collection and intelligent recognition technology, and at the same time, the data information of the construction object recorded synchronously is uploaded and saved to the cloud database. Specifically, the quality of the finished water-brushed stone finishing products of the construction object after the construction is completed is monitored: the same visual acquisition equipment is used to capture visual data of the finished water-brushed stone finishing products of the construction object after the construction is completed, and intelligent recognition is performed at the same time to achieve accurate comparison with the visual data of the reference finishing of the construction object, thereby realizing the closed loop of the water-brushed stone slurry finishing construction process, ensuring the stability of the quality of the obtained water-brushed stone slurry, and at the same time uploading and saving the data information of the construction object recorded synchronously to the cloud database, the data information of the construction object recorded synchronously includes actual mixing ratio information, visual data, and ratio record date, which is used to improve the cloud database information, and to increase the training data basis of the machine learning algorithm to improve the accuracy of the visual recognition algorithm model, so that the same proportion data can be directly obtained in future repairs to meet the requirements of fast data reading and accurate ratio identification during repair and restoration construction.

[0053] In the semi-automatic production procedure of quick-setting templates and the automatic production procedure of water-brushed stone slurry for construction, the specific steps of automatic material discharge and mixing are as follows: according to the ratio information and the total amount, the theoretical amount of raw materials in each silo is automatically calculated, and the timing of opening and closing of the discharge valve of the silo is determined by monitoring the real-time data of the weighing sensor to control the precise batching. Specifically, according to the preset discharge sequence and the required raw materials in the ratio information, the discharge valve of each silo is controlled to open automatically in turn, and the actual amount of raw materials fed is monitored in real time by the weighing sensors arranged in each silo. When the actual amount of raw materials fed reaches the theoretical amount, the discharge valve of each silo is automatically closed and synchronized to the cloud database through wireless data transmission, so as to achieve the accuracy of material discharge and ensure that the proportion of raw materials in each batch of mixed water-brushed stone slurry can be traced, which is convenient for quality control and subsequent analysis. In another embodiment, before automatic material discharge and mixing, the type and balance of raw materials in each silo are confirmed based on the ratio information and the total amount: when the silo lacks the corresponding raw materials in the ratio and / or the balance of raw materials in the silo is less than the theoretical amount, an alarm is issued to prompt the construction personnel to replenish and / or replace the raw materials; when the silo has the corresponding raw materials in the ratio and the balance of raw materials in the silo is not less than the theoretical amount, the discharge valves of each silo are opened in sequence according to the preset discharge sequence and automatic material discharge and mixing are performed. Among them, the ratio information and total amount refer to the initial ratio and the total amount of the sample in the semi-automatic production program of the quick-setting sample, and refer to the actual mixing ratio and the total amount of construction in the automatic production program of the water-brushed stone slurry. When all the raw materials have been added, the viscosity of the water-brushed stone slurry is continuously stirred and monitored until the viscosity of the water-brushed stone slurry meets the requirements and then the slurry is discharged from the slurry discharge channel for standby use; in the present embodiment, the viscosity of the water-brushed stone slurry is monitored in real time through the rotational torque feedback data of the servo motor. In addition, in another embodiment, the surface state of the water-brushed stone slurry can be assisted by a visual module to monitor the surface state of the water-brushed stone slurry, such as the surface ripple calming time, to assist in comprehensive judgment of the viscosity of the water-brushed stone slurry under the current stirring state; when the change data of the rotational torque feedback and the surface ripple calming time of the water-brushed stone slurry fall within the range of previous experimental data, it is determined that the viscosity of the water-brushed stone slurry has met the requirements.

[0054] In other embodiments, the system is further provided with a fault monitoring unit, which is electrically connected to the control unit. During the automatic discharging and mixing process, the fault monitoring unit monitors the discharging status of each silo in real time by monitoring the weighing sensor data of each silo. Once an abnormality is detected, the fault position is automatically diagnosed and located. When the actual discharge amount obtained by the weighing sensor of any silo continues to fail to reach the corresponding theoretical amount of raw materials under the preset discharging sequence, the silo is judged to be faulty. In actual work, there may be a situation where the raw material is stuck in the discharge valve and cannot fall or the discharge valve itself fails and cannot be opened and closed. The system automatically controls the discharge valve at the corresponding silo to open and close multiple times to try to repair the fault. If the fault is still not resolved, an alarm is triggered to prompt the corresponding fault position and manual unblocking or repair is performed, thereby achieving timely response and processing of the fault and ensuring production continuity.
