Description

Technical Field

[0001] This invention relates to the field of control and analysis technology, specifically to a method and system for scheduling concrete pumping in long-distance construction. Background Technology

[0002] In coal mine construction, concrete is typically pre-processed on the surface and then transported underground by trucks. However, due to factors such as temperature, distance, and scheduling, the concrete prepared on the surface often deteriorates by the time it reaches the underground construction site, affecting construction quality. To improve the efficiency and quality of mine construction, widely used surface construction machinery is being applied underground, allowing for convenient concrete processing and improving the surface environment. Furthermore, to better ensure the efficiency and quality of concrete construction in mines, the industrial process of concrete production needs to be automated.

[0003] In the process of automating the industrial process of concrete in mine construction, the pumping stage is more important and easier to adjust than other stages. The pumping stage occurs in the underground coal mine setting. It receives concrete materials transported from the surface, mixes them, and then controls the pouring of the concrete materials outward through a pumping device. During the pumping process, because the concrete materials are exposed to the elements from beginning to end, they are affected by the underground coal mine environment, resulting in different solidification states. This affects the completion progress of the pumping stage, thereby hindering the progress of other coordinating stages, such as batching and transportation, and impacting the efficiency of automating the industrial process of concrete in mine construction. Summary of the Invention

[0004] To address the technical problems in the prior art, the present invention aims to provide a concrete pumping scheduling method and system for long-distance construction, the specific technical solution of which is as follows: The first aspect of this application provides a method for scheduling concrete pumping in long-distance construction, the method comprising: During the underground concrete pumping process, the transportation power and duration at each moment in the transportation stage, the weight and pressure data of the pumping hopper, and the temperature difference data between the ground and underground are obtained. The pumping replenishment efficiency is analyzed based on the transportation power and duration of the current transportation phase; the replenishment efficiency is adjusted according to the changes in the weight and pressure data of the pumped pumps in consecutive time periods before the current time to determine the output efficiency at the current time; and the coordination anomaly time is determined by the replenishment efficiency and output efficiency. When a coordination anomaly occurs, the solidification assessment index for each historical moment is determined based on the transportation duration and temperature difference data accumulation at each historical moment in the transportation period. Discharge judgment is made by accumulating solidification assessment indices across consecutive historical moments, iteratively determining each safe discharge period and the pumping mixing period at the coordination anomaly. The safety difference time difference at the coordination anomaly is determined by the difference between the overall historical safe discharge period and the pumping mixing period. Finally, the environmental intervention assessment index for the coordination anomaly is determined by the solidification assessment index at the coordination anomaly and the safety difference time difference. The pumping power at any given time is adjusted based on the magnitude of the environmental intervention assessment indicators.

[0005] Furthermore, the method for obtaining the supply efficiency includes: Obtain the transportation duration in the current transportation stage, normalize the product of the transportation duration and the transportation power, and obtain the replenishment efficiency at the current moment.

[0006] Furthermore, the method for obtaining the output efficiency includes: After calculating the difference between the weight and pressure data at each time point before the current time point in the transportation phase and the previous time point, the average of all differences is used as the output reference value at the current time point; the normalized value of the output reference value is used as the adjustment value. When the output reference degree is negative, the sum of the supply efficiency and the adjustment value is used as the output efficiency at the current moment; when the output reference degree is positive, the difference between the supply efficiency and the adjustment value is used as the output efficiency at the current moment. When the output reference degree is zero, the replenishment efficiency is used as the output efficiency at the current moment.

[0007] Furthermore, the method for determining the moment of coordination anomaly includes: By negatively mapping the difference between supply efficiency and output efficiency, a coordination evaluation index can be obtained. If the coordination evaluation index at the current moment is less than the preset coordination threshold, the current moment will be regarded as an abnormal coordination moment.

[0008] Furthermore, the method for obtaining the solidification evaluation index includes: The period from the start time of the transportation segment in which the historical moment is located to the historical moment itself is taken as the analysis period for that historical moment; the average temperature difference data of all moments in the analysis period is taken as the average temperature difference of that historical moment. The ratio of the transportation duration of the historical moment to the preset time limit during the transportation period is used as the transportation duration impact of the historical moment. The sum of the average temperature difference at all historical moments in the analysis period is normalized to obtain the influence of transportation temperature at that historical moment. By combining the impact of transportation time and transportation temperature at this historical moment, a solidification assessment index is obtained for that historical moment.

[0009] Furthermore, the step of using accumulated solidification evaluation indicators from continuous historical time points to determine discharge criteria, and iteratively determining each safe discharge period and the pumping mixing period at coordinated abnormal times, includes: For any point in the historical timeline, within the preset analysis window at that point, that point is taken as the initial pouring sequence, and the next point is successively incorporated into the initial pouring sequence. The mean of the solidification evaluation index of all points in the initial pouring sequence is calculated as the solidification mean. When the average solidification value is greater than the preset solidification threshold, the merging is stopped and the time period corresponding to the initial pouring sequence at this time is taken as a safe discharge time period; the initial pouring sequence is formed iteratively with the next time of the safe discharge time period and the safe discharge time period is determined. The initial pouring sequence is stopped when it is incorporated into the coordination anomaly moment, and the last initial pouring sequence is taken as the pumping mixing period.

[0010] Furthermore, the method for obtaining the security difference time difference includes: Calculate the average duration of all historical safe discharge periods, and use the difference between the average duration and the duration of the pumping mixing period as the safety difference time difference.

[0011] Furthermore, the method for obtaining the environmental intervention assessment indicators includes: The sum of the transportation time and the safety difference time difference during the transportation period of the coordination anomaly moment is used as the expected discharge time; the ratio of the expected discharge time to the preset limit time is used as the duration intervention degree of the coordination anomaly moment. The product of the duration of intervention during the coordination anomaly and the solidification assessment index is normalized to obtain the environmental intervention assessment index for the coordination anomaly.

[0012] Furthermore, the adjustment of pumping power at a given time based on the magnitude of environmental intervention assessment indicators includes: When the environmental intervention assessment index is greater than the preset intervention threshold, the product of the environmental intervention assessment index and the preset pumping power is used as the adjustment value; the sum of the preset pumping power and the adjustment value is used as the adjustment power. The pumping device operates at an adjusted power until the environmental intervention assessment index is less than or equal to the preset intervention threshold, at which point the pumping device operates at the preset pumping power.

[0013] Secondly, this application provides a concrete pumping dispatching system for long-distance construction, the system comprising: The data acquisition module is used to acquire the transportation power and duration at each moment in the transportation stage during the underground concrete pumping process, the weight and pressure data of the pumping hopper, and the temperature difference data between the ground and underground. The coordination anomaly analysis module is used to analyze the pumping replenishment efficiency based on the transportation power and duration of the transportation phase at the current moment; adjust the replenishment efficiency according to the changes in the weight and pressure data of the pumped pumps in consecutive moments before the current moment to determine the output efficiency at the current moment; and determine the coordination anomaly moment by using the replenishment efficiency and output efficiency. The environmental intervention assessment module is used to determine the solidification assessment indicators for each historical moment when a coordination anomaly occurs, based on the transportation duration and temperature difference data accumulation at each historical moment in the transportation period. It then uses the accumulated solidification assessment indicators from consecutive historical moments to determine discharge criteria, iteratively identifying each safe discharge period and the pumping mixing period at the coordination anomaly. Finally, it determines the safety difference time difference at the coordination anomaly by comparing the overall historical safe discharge periods with the pumping mixing period, and finally, it determines the environmental intervention assessment indicators for the coordination anomaly based on the solidification assessment indicators and the safety difference time difference at the coordination anomaly. The adjustment module is used to adjust the pumping power at any given time based on the magnitude of the environmental intervention assessment indicators.

[0014] Thirdly, this application provides a computer device including a memory and a processor. The memory is used to store computer program code, and the processor is used to call and run the computer program code from the memory to perform the method as described in the first aspect of this application or any embodiment of the first aspect.

[0016] Fifthly, this application provides a computer-readable storage medium that stores computer program code, which, when executed, performs the method as described in the first aspect of this application or any embodiment thereof.

[0017] The present invention has the following beneficial effects: This invention analyzes the output and replenishment efficiency of the pumping device during operation to reflect the degree of coordination between the pumping device and the entire concrete material handling process. This allows for the identification of coordination anomalies and further adjustments to ensure smooth scheduling. The invention further analyzes the potential for concrete solidification during pumping due to the influence of underground coal mine temperatures. This analysis divides the safe discharge of concrete materials in the pumping process into time periods. For the pumping and mixing stage where complete safe discharge has not been achieved before the moment of coordination anomaly, the invention determines the required safety difference time difference for predicting the current moment of coordination anomaly. By combining solidification assessment indicators with the safety difference time difference to reflect the potential for intervention at the current moment of coordination anomaly, power adjustments are made to ensure smooth scheduling. This invention determines the adjustment time by analyzing transportation coordination and assesses the degree of environmental intervention based on temperature difference interference, leading to subsequent power scheduling adjustments. This improves the smoothness of coordination between the pumping process and other coordinating processes, enhancing the accuracy and reliability of automated efficiency control.

[0020] To further illustrate the technical means and effects adopted by the present invention to achieve its intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of a concrete pumping scheduling method and system for long-distance construction proposed according to the present invention. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0022] The following description, in conjunction with the accompanying drawings, details a specific scheme for a concrete pumping scheduling method and system for long-distance construction provided by the present invention.

[0023] Please see Figure 1 The diagram illustrates a flowchart of a concrete pumping scheduling method for long-distance construction, according to an embodiment of the present invention. The method includes the following steps: S1: During the underground concrete pumping process, acquire the transportation power and duration at each moment in the transportation stage, the pressure data of the pumping hopper, and the temperature difference data between the ground and underground.

[0024] The pumping process of underground concrete is mainly divided into three stages: surface batching, underground transportation, and underground pumping. The surface batching and underground transportation stages are controlled by constant power. The transportation time in the underground transportation stage is constant. In this embodiment, the transportation time is 30 minutes and the transportation power is 260kW. Specific values ​​can be adjusted by the implementer according to the specific implementation method, and are not limited here.

[0025] During the operation of the pumping device, real-time data on the weight and pressure of the pumping device hopper is collected, along with data on the ground temperature and the temperature inside the coal mine. The difference between the underground coal mine temperature and the ground temperature is used as temperature difference data for subsequent analysis of environmental interference. It should be noted that data acquisition is a technique well-known to those skilled in the art and will not be elaborated upon here.

[0026] S2: Analyze the pumping replenishment efficiency based on the transportation power and duration of the current transportation phase; adjust the replenishment efficiency according to the changes in the weight and pressure data of the pumped pumps in consecutive time periods before the current time, and determine the output efficiency at the current time; determine the coordination anomaly time through the replenishment efficiency and output efficiency.

[0027] In real-world scenarios, concrete materials primarily undergo production, transportation, and pumping. Ideally, these three processes coordinate to form a smooth, automated control process. While production and transportation are controlled at constant levels, this doesn't mean the concrete material's state remains stable throughout these processes. Because concrete is essentially exposed throughout the entire process, it comes into direct contact with the external environment, causing its physical state to gradually shift from liquid to near-solid. The external environment—between the surface and underground mines—changes. Therefore, if an anomaly occurs in the pumping process, it's highly likely that the concrete material in the preceding processes has already begun to deteriorate, resulting in significant incoordination within the entire process and hindering seamless integration between different stages.

[0028] Therefore, the efficiency of pumping operations can be analyzed to assess the coordination of each link. In actual scenarios, the concrete materials prepared in the production process are directly transported to the pumping device via the transport device. Therefore, by analyzing the transportation situation in the underground transportation stage of the surface coal mine at the current moment, the supply efficiency can be reflected.

[0029] In this embodiment of the invention, the transportation duration in the current transportation stage is obtained, and the product of the transportation duration and the transportation power is normalized to obtain the replenishment efficiency at the current moment. The replenishment efficiency indirectly reflects the total amount of concrete transported to the well. The higher the replenishment efficiency, the higher the total transportation volume.

[0030] It should be noted that normalization is a technique well known to those skilled in the art. The choice of normalization can be linear normalization or standard normalization, etc., and the specific normalization method is not limited here.

[0031] When the pumping device discharges, it reduces the amount of concrete material in the hopper and the weight on the hopper. However, considering that the pumping device will also continuously receive materials transported by the transport device, the output may vary due to the dynamic replenishment.

[0032] In this embodiment of the invention, after calculating the difference between the weight and pressure data at each time point before the current time point in the transportation stage and the previous time point, the average of all differences is used as the output reference value at the current time, reflecting the net weight change trend of the material in the hopper. The normalized value of the output reference value is used as the adjustment value, representing the degree of adjustment. When the output reference value is negative, it indicates that the material in the hopper is continuously decreasing, and the pumping output is higher than the transportation replenishment. The sum of the replenishment efficiency and the adjustment value is used as the output efficiency at the current time.

[0033] When the output reference value is positive, it indicates that the material in the hopper is continuously increasing, and the pumping output is lower than the transport supply. The difference between the supply efficiency and the adjustment value is taken as the output efficiency at the current moment. When the output reference value is zero, it indicates that the material inflow and outflow are balanced, and the supply efficiency is taken as the output efficiency at the current moment.

[0034] The balance between supply efficiency and output efficiency reflects the degree of coordination among various stages. In this embodiment of the invention, the difference between supply efficiency and output efficiency is negatively correlated to obtain a coordination evaluation index. The more consistent the supply efficiency and output efficiency are, i.e., the smaller the difference, the larger the coordination evaluation index, indicating that the connection between the stages is smoother and more coordinated at the current moment. It should be noted that negative correlation mapping is a technique well known to those skilled in the art, and can be in the form of an inverse proportional value or a negative exponent with a natural constant as the base. It will not be elaborated or limited here.

[0035] Therefore, if the coordination evaluation index at the current moment is less than the preset coordination threshold, it indicates that there is a significant coordination asynchrony and adjustment is required. The current moment is taken as the coordination abnormal moment. In this embodiment of the invention, the preset coordination threshold is set to 0.45, and the implementer can adjust the specific value as needed.

[0036] Therefore, by analyzing the coordination of the pumping device in the entire concrete material handling process at the current moment, the abnormal moments of coordination that require adjustment analysis can be identified.

[0037] S3: When there is a coordination anomaly, based on the transportation duration and temperature difference data accumulation of each historical moment in the historical time series, determine the solidification assessment index for that historical moment; use the accumulated solidification assessment index of consecutive historical moments to make discharge judgments, and iteratively determine each safe discharge period and the pumping mixing period at the coordination anomaly moment; determine the safety difference time difference at the coordination anomaly moment by the difference between the overall historical safe discharge period and the pumping mixing period; determine the environmental intervention assessment index at the coordination anomaly moment by the solidification assessment index and the safety difference time difference.

[0038] In the "ground batching + underground mixing and pumping" model, the underground coal mine environment differs significantly from the surface environment, exhibiting substantial environmental constraints. The underground coal mine environment, typically in the form of tunnels, is more limited and enclosed, resulting in poor air circulation and hindering effective heat dissipation. Furthermore, because concrete materials are exposed during transportation, and are sensitive to external temperatures, ambient temperature is the primary factor constraining the physical state of the concrete materials in the underground coal mine environment.

[0039] Therefore, after determining the moment of coordination anomaly, it is necessary to analyze the degree to which the concrete is constrained by the underground coal mine temperature during pumping. First, the solidification assessment index corresponding to that moment is analyzed. In this embodiment of the invention, the method for obtaining the solidification assessment index includes: For any given historical moment, the period from the start of the transportation phase to that historical moment is taken as the analysis period, reflecting the time from the start of transportation to that historical moment. The average temperature difference data of all moments within the analysis period is taken as the average temperature difference of that historical moment. The larger the average temperature difference, the more drastic the temperature changes experienced by the concrete material flowing into the pumping device before that historical moment, and the more significant the impact on the physical state of the concrete material itself.

[0040] Because concrete is continuously exposed to the outside, it will inevitably continue to solidify, and the moisture it contains will continue to evaporate. Considering the life cycle characteristics of concrete, there is a strict time limit from leaving the factory to completion of pouring, usually not exceeding 120 minutes. In this embodiment of the invention, the preset time limit is set to 105 minutes. Furthermore, the ratio of the transportation time of the historical moment in the current transportation period to the preset time limit is used as the transportation time influence degree of the historical moment. The higher the transportation time influence degree, the longer the transportation time, and the higher the possibility of solidification.

[0041] Then, the sum of the average temperature differences at all historical moments within the analysis period is normalized to obtain the transportation temperature influence at that historical moment, reflecting the overall temperature influence of the preceding events. Finally, by combining the transportation duration influence and the transportation temperature influence at that historical moment, a solidification assessment index is obtained. In this embodiment of the invention, the product of the transportation duration influence and the transportation temperature influence is used as the solidification assessment index at that historical moment. The larger the solidification assessment index, the more moisture may evaporate from the new concrete material received by the pumping device during transportation, and the greater the degree of solidification.

[0042] Ideally, concrete should be poured before it fully hardens during the pumping process. In actual production, a hardening threshold is usually set to maximize the final solidification effect. Therefore, after entering the funnel, the concrete material is not immediately discharged from the pumping device; it needs to be discharged continuously over a period of time. At this point, the concrete material is still exposed and is significantly constrained by the underground coal mine environment. The more liquid the concrete material is in this state, the greater and wider its penetration into the surface structure after pumping, resulting in a more stable and safer overall solid structure after final solidification.

[0043] Therefore, based on the cumulative historical solidification levels, the analysis is conducted to determine the time period before the expected solidification level is reached. This measures the duration during which newly received concrete material in the pumping device is basically discharged from the funnel in historical data, and simultaneously determines the pumping period before the coordination anomaly, in order to facilitate the discharge time required for subsequent analysis.

[0044] In this embodiment of the invention, for any point in the historical timeline, within the analysis window of that point, that point is used as the initial pouring sequence. Subsequent points are then sequentially incorporated into the initial pouring sequence, and the average of the solidification evaluation indicators for all points in the initial pouring sequence is calculated as the solidification mean. The solidification mean is calculated once for each added point. The preset analysis window is a 2-minute window after each point; the specific value can be adjusted by the implementer.

[0045] When the average solidification value exceeds the preset solidification threshold, the merging process stops, and the time period corresponding to the initial pouring sequence at this point is considered a safe discharge period. This indicates that the solidification has reached its limit, and concrete pours at this time can be safely and ideally discharged. Specifically, if the merging time is the last moment of the analysis window, it means that the ideal baseline discharge threshold has not been reached over a relatively long period, and the process should be stopped promptly, with the time period corresponding to the initial pouring sequence at this point considered a safe discharge period. In this embodiment of the invention, the preset solidification threshold is set to 0.6, but the implementer can adjust the specific value as needed.

[0046] The initial pouring sequence is formed iteratively from the next moment of the safe discharge period, and the safe discharge period is determined. After the safe discharge period is determined, the subsequent iterations obtain the safe discharge period. When the timing is close to the coordination anomaly moment, if the cumulative threshold judgment is not met, it is considered that the discharge is still in progress. Therefore, the initial pouring sequence stops when it is merged into the coordination anomaly moment, and the last initial pouring sequence is taken as the pumping mixing period.

[0047] By analyzing the safe discharge period, a difference analysis can be performed on the pumping mixing period to assess the time difference between the current coordination anomaly period and complete discharge. In this embodiment of the invention, the method for obtaining the safe difference time difference includes: Calculate the average duration of all historical safe discharge periods, and use the difference between the average duration and the duration of the pumping and mixing period as the safety difference time difference, indicating how much time is needed to reach a fully safe discharge state after the current coordination anomaly.

[0048] By combining the safety difference time difference, the moment of coordination anomaly, and the transportation duration, a comprehensive assessment is made to predict the time required for complete discharge. The closer this time is to the limit, the less ideal the transportation duration and the higher the degree of intervention. The methods for obtaining the final environmental intervention assessment indicators, based on the solidification assessment indicators at the moment of coordination anomaly, include: The sum of the transportation time and the safety difference time difference during the transportation period of the coordination anomaly is used as the expected discharge time. The ratio of the expected discharge time to the preset limit time is used as the duration intervention degree of the coordination anomaly. The larger the duration intervention degree, the closer the assessed expected discharge time is to the limit, and the higher the potential impact.

[0049] Furthermore, the product of the duration intervention degree of the coordination anomaly and the solidification assessment index is normalized to obtain the environmental intervention assessment index of the coordination anomaly. The greater the degree of solidification and the higher the duration influence, the higher the degree of environmental intervention of the underground coal mine environment on pumping scheduling.

[0050] S4: Adjust the pumping power at any given time based on the magnitude of the environmental intervention assessment index.

[0051] The required power adjustment is further determined by environmental intervention assessment indicators. In this embodiment of the invention, when the environmental intervention assessment indicator is greater than the preset intervention threshold, it indicates a high degree of intervention impact. The product of the environmental intervention assessment indicator and the preset pumping power is used as the adjustment value, and the sum of the preset pumping power and the adjustment value is used as the adjustment power. By increasing the power and scheduling in advance, the smooth connection of the concrete transportation process is ensured. In this embodiment of the invention, the preset intervention threshold is set to 0.4. The specific perceived threshold and preset pumping power can be adjusted by the implementer according to the specific implementation scenario, and are not limited here.

[0052] The pumping device operates at regulated power until the environmental intervention assessment index is less than or equal to the preset intervention threshold, indicating a reduction in the degree of intervention. The pumping device then operates at the preset pumping power to maintain efficient transportation at normal power. At the end of transportation, the automatic control device on the pumping device can drive a reverse pumping operation to return the concrete in the S-pipe to the hopper, completing intelligent scheduling of concrete pumping for long-distance construction.

[0053] In summary, this invention analyzes the output and replenishment efficiency of the pumping device during operation to reflect the degree of coordination between the pumping device and the entire concrete material handling process. This allows for the identification of coordination anomalies and further adjustments to ensure smooth scheduling. Further analysis of the potential for concrete solidification during pumping due to the influence of underground coal mine temperatures allows for the segmentation of safe discharge timeframes in the pumping process. For pumping and mixing stages where complete safe discharge has not been achieved before the point of coordination anomaly, the required safety difference time difference for predicting the current coordination anomaly is determined. The solidification assessment index and the safety difference time difference comprehensively reflect the potential for intervention at the current coordination anomaly point, enabling power adjustment and ensuring smooth scheduling. This invention determines the adjustment time by analyzing transportation coordination and assesses the degree of environmental intervention based on temperature difference interference, leading to subsequent power scheduling adjustments. This improves the smoothness of coordination between the pumping process and other coordinating processes, enhancing the accuracy and reliability of automated efficiency control.
