Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a digital management and tracking method for the production of prefabricated exterior walls. Background Technology

[0002] With the advancement of industrialized construction, prefabricated exterior walls are widely used in prefabricated building construction due to their advantages of high efficiency and standardization. However, the traditional prefabricated exterior wall production process suffers from problems such as low levels of informatization, lagging quality control, and lack of transparency in production progress.

[0003] Currently, production data largely relies on manual recording, which is prone to missing or incorrect information, making quality traceability difficult. Quality inspection is scattered across various processes, and the data lacks a systematic correlation, making it difficult to provide real-time feedback on production status. Production progress tracking depends on experience-based judgment, lacking dynamic and visualized management methods, which can easily lead to resource waste or delays. In addition, traditional production models lack systematic analysis of the production cycle and cannot optimize production parameters based on data, resulting in large fluctuations in pass rates and unstable production efficiency.

[0004] While some companies have attempted to introduce barcode or RFID technology for identification management, these technologies are mostly limited to data recording in a single stage and have failed to achieve end-to-end digital integration and intelligent analysis. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a digital management and tracking method for prefabricated exterior wall production, so as to solve the problems mentioned in the background art.

Step 2: Conduct quality inspection on the completed precast exterior walls, including dimensional quality inspection and mechanical performance testing. Obtain the quality inspection results and associate them with the corresponding RFID tags of the precast exterior walls, then upload them to the cloud database. The quality inspection results include qualified and unqualified. Step 3: Use RFID tags to read the production data of the prefabricated exterior wall in real time, compare it with the preset production plan, and track the production progress of the prefabricated exterior wall in real time; Step 4: Perform periodic analysis on prefabricated exterior wall production, including: periodically calculating the quality pass rate and production rate of prefabricated exterior walls, summarizing them to form a production evaluation coefficient; comparing the obtained production evaluation coefficient with the preset evaluation threshold; if the obtained production evaluation coefficient is less than the evaluation threshold, an alarm is issued and the production operation parameters in the prefabricated exterior wall production within that period are optimized.

[0007] Preferably, in step one, the method for obtaining production data is as follows: S101. Based on the design drawings of the prefabricated exterior wall, obtain the design information of the prefabricated exterior wall, including design dimension information and mechanical performance design standards; wherein, the design dimension information refers to the geometric dimension parameters of the prefabricated exterior wall; the mechanical performance design standards include the standard value of load-bearing capacity; S102. Collect information on raw materials required for the production of precast exterior walls, including the specifications, batch numbers, arrival time, and quality inspection reports of the raw materials; among which, the raw materials required for the production of precast exterior walls include concrete, steel bars, and admixtures. S103. By deploying various sensors at each production process of the prefabricated exterior wall, the operating parameters of the production equipment and production progress information are collected in real time.

[0008] Preferably, the production data for the precast exterior wall is determined based on the collected design information, raw material information, production equipment operating parameters, and production progress information.

Use a laser scanner to measure the completed prefabricated exterior wall to obtain the actual size information of the prefabricated exterior wall; when measuring the actual size of the prefabricated exterior wall, multiple tests are required, and abnormal data is removed before taking the average value. S202. Compare the geometric dimension parameters of the actual dimensions of the precast exterior wall with the design dimensions, and calculate the absolute value of the dimensional deviation of the precast exterior wall. S203. Compare the absolute value of the dimensional deviation with the corresponding preset deviation threshold. If the absolute value of the dimensional deviation is less than or equal to the deviation threshold of the corresponding dimension, it indicates that the dimensional quality of the prefabricated exterior wall is qualified; otherwise, an abnormal signal is triggered and the prefabricated exterior wall is marked as unqualified.

[0010] Preferably, the process of quality inspection of the completed prefabricated exterior walls also includes: S204. The maximum load-bearing capacity of the prefabricated exterior wall is obtained by conducting mechanical performance tests on the completed prefabricated exterior wall, i.e., the actual load-bearing capacity test value. Among them, when testing the mechanical performance of the prefabricated exterior wall, multiple sets of tests need to be conducted, and the average value is taken after removing abnormal data. S205. Obtain the standard value of bearing capacity. By establishing a bearing capacity assessment model, obtain the bearing capacity assessment value to test and evaluate the mechanical performance of the precast exterior wall. If the bearing capacity assessment value is 1, it means that the mechanical performance of the precast exterior wall is qualified. If the bearing capacity assessment value is 0, an abnormal signal is triggered and the precast exterior wall is marked as unqualified. S206. Based on S201 to S205, obtain prefabricated exterior walls that pass dimensional quality inspection and mechanical performance inspection, and mark the prefabricated exterior walls as qualified.

[0011] Preferably, in S205, the expression for the bearing capacity assessment model is: ; In the formula, CP(SJ) represents the load-bearing capacity assessment value; SJ is the actual load-bearing capacity test value; and CB is the standard load-bearing capacity value.

[0012] Preferably, in step three, the process of tracking the production progress of the prefabricated exterior wall includes: S301. Based on the production data of prefabricated exterior walls, obtain the corresponding production progress information, and obtain the actual time consumed by each production process by calculating the difference between the actual start time and the actual end time of each production process. S302. Similarly, based on the pre-set production plan, calculate the planned time for each production process of the corresponding prefabricated exterior wall. S303. By calculating the difference between the actual time and the planned time in each production process of the prefabricated exterior wall, a production progress tracking record is generated and compared with the preset progress deviation threshold of the corresponding production process. Then, a production progress prompt signal is generated. The production progress tracking record includes the progress deviation of each production process of the prefabricated exterior wall.

[0013] Preferably, in S303, the comparison process includes: If the progress difference of the corresponding production process is greater than or equal to the progress deviation threshold, it indicates that the progress of the production process is abnormal and an abnormality prompt signal is generated. If the progress difference of the corresponding production process is less than the progress deviation threshold, it indicates that the progress of the production process is normal and a normal prompt signal is generated. Abnormal or normal error signals constitute production progress indication signals.

[0014] Preferably, in step four, the process of periodically analyzing the production of prefabricated exterior walls includes: S401. Periodically traverse the quality inspection results of prefabricated exterior walls to obtain the number of qualified and unqualified prefabricated exterior walls, and calculate the quality pass rate of prefabricated exterior walls within this period. The calculation formula is as follows: ; In the formula, HL is the quality pass rate of prefabricated exterior walls within the period; HG is the number of qualified prefabricated exterior walls; and BG is the number of unqualified prefabricated exterior walls. S402. Calculate the production rate of prefabricated exterior walls within a preset period by statistically analyzing the actual total output of prefabricated exterior walls within that period. The calculation formula is as follows: ; In the formula, V is the production rate of prefabricated exterior walls within a cycle; YT is the preset cycle.

[0015] Preferably, the process of periodically analyzing the production of prefabricated exterior walls further includes: S403. Normalize and summarize the quality pass rate and production rate of precast exterior walls within the cycle to form a production evaluation coefficient. ; In the formula, P is the production evaluation coefficient; and This represents the weighting coefficients corresponding to the quality pass rate and production rate, and ; S404. Compare the obtained production evaluation coefficient with the preset evaluation threshold. If the obtained production evaluation coefficient is less than the evaluation threshold, issue an alarm and optimize the production operation parameters in the prefabricated exterior wall production within the cycle, including adjusting the values ​​of the production operation parameters in the prefabricated exterior wall production, until the recalculated production evaluation coefficient is greater than or equal to the evaluation threshold.

[0016] Compared to existing solutions, the beneficial effects achieved by this invention are: This invention uses RFID tags to bind production data and quality inspection results, enabling digital recording of the entire lifecycle from raw material processing, molding and curing to quality inspection, and achieving precise traceability of production data for each precast exterior wall.

Collect information on raw materials required for the production of precast exterior walls, including the specifications, batch numbers, arrival time, and quality inspection reports of the raw materials; among which, the raw materials required for the production of precast exterior walls include concrete, steel bars, and admixtures. S103. By deploying various sensors in each production process of prefabricated exterior walls, production operation parameters and production progress information are collected in real time. The production operation parameters include, but are not limited to, mixing time, vibration frequency, and mold temperature; production progress information is obtained by recording the actual start and end times of each production process of the precast exterior wall; furthermore, the production processes of the precast exterior wall include, but are not limited to, concrete pouring, vibration, and curing. Based on the collected design information, raw material information, production equipment operating parameters and production progress information, the production data of the precast exterior wall is determined. It should be further explained that the RFID tags are radio frequency tags, and each RFID tag has a unique ID number to identify the corresponding prefabricated exterior wall, enabling accurate tracking.

[0021] Step 2: Conduct quality inspection on the completed precast exterior walls, including dimensional quality inspection and mechanical performance testing. Obtain the quality inspection results and associate them with the corresponding RFID tags of the precast exterior walls, then upload them to the cloud database. The quality inspection results include qualified and unqualified. It should be further explained that, in the specific implementation process, the quality inspection of the completed prefabricated exterior walls includes: S201. Use a laser scanner to measure the completed prefabricated exterior wall to obtain the actual size information of the prefabricated exterior wall; when measuring the actual size of the prefabricated exterior wall, multiple tests are required, and abnormal data is removed before taking the average value. S202. Compare the geometric dimensional parameters of the actual dimensions of the prefabricated exterior wall with those of the design dimensions, and calculate the absolute value of the dimensional deviation of the prefabricated exterior wall; wherein, the absolute value of the dimensional deviation includes, but is not limited to, the absolute value of the length deviation, the absolute value of the height deviation, and the absolute value of the width deviation. S203. Compare the absolute value of the dimensional deviation with the corresponding preset deviation threshold. If the absolute value of the dimensional deviation is less than or equal to the deviation threshold of the corresponding dimension, it indicates that the dimensional quality of the prefabricated exterior wall is qualified; otherwise, an abnormal signal is triggered and the prefabricated exterior wall is marked as unqualified. Among them, the preset deviation threshold is the deviation threshold for different dimensions, and the specific value is set by experts in this field in combination with the design requirements of prefabricated exterior walls in actual production tasks; S204. The maximum load-bearing capacity of the prefabricated exterior wall is obtained by conducting mechanical performance tests on the completed prefabricated exterior wall, i.e., the actual load-bearing capacity test value. Among them, when testing the mechanical performance of the prefabricated exterior wall, multiple sets of tests need to be conducted, and the average value is taken after removing abnormal data. S205.

S206. Based on S201 to S205, obtain prefabricated exterior walls that pass dimensional quality inspection and mechanical performance inspection, and mark the prefabricated exterior walls as qualified. It should be further explained that, based on the quality inspection results, RFID tags can be scanned on substandard precast exterior walls to obtain and analyze their production data, thereby determining the reasons for the substandard quality inspection results and enabling digital tracking and tracing of substandard precast exterior walls; for example, Step 3: Use RFID tags to read the production data of the prefabricated exterior wall in real time, compare it with the preset production plan, and track the production progress of the prefabricated exterior wall in real time; It should be further explained that, in the specific implementation process, the process of tracking the production progress of prefabricated exterior walls includes: S301.

S302. Similarly, based on the pre-set production plan, calculate the planned time for each production process of the corresponding prefabricated exterior wall. S303. By calculating the difference between the actual time and the planned time in each production process of the prefabricated exterior wall, a production progress tracking record is generated and compared with the preset progress deviation threshold of the corresponding production process. Then, a production progress prompt signal is generated. The production progress tracking record includes the progress deviation of each production process of the prefabricated exterior wall. If the progress difference of the corresponding production process is greater than or equal to the progress deviation threshold, it indicates that the progress of the production process is abnormal and an abnormality prompt signal is generated. If the progress difference of the corresponding production process is less than the progress deviation threshold, it indicates that the progress of the production process is normal and a normal prompt signal is generated. Anomaly alerts or normal alerts constitute production progress alerts; It should be noted that the preset schedule deviation threshold is a key parameter for balancing production efficiency and flexibility, and needs to be dynamically set and corrected by those skilled in the art in combination with historical production data and equipment process characteristics; in addition, the schedule deviation value is an absolute value. Step 4: Perform periodic analysis on prefabricated exterior wall production, including: periodically calculating the quality pass rate and production rate of prefabricated exterior walls, summarizing them, and forming a production evaluation coefficient; comparing the obtained production evaluation coefficient with the preset evaluation threshold; if the obtained production evaluation coefficient is less than the evaluation threshold, an alarm is issued and the production operation parameters in the prefabricated exterior wall production within that period are optimized.

Normalize and summarize the quality pass rate and production rate of precast exterior walls within the cycle to form a production evaluation coefficient. ; In the formula, P is the production evaluation coefficient; and This represents the weighting coefficients corresponding to the quality pass rate and production rate, and Its specific value can be adjusted and modified by experts in the field according to actual design requirements; S404. Compare the obtained production evaluation coefficient with the preset evaluation threshold. If the obtained production evaluation coefficient is less than the evaluation threshold, issue an alarm and optimize the production operation parameters in the prefabricated exterior wall production within the cycle, including adjusting the values ​​of the production operation parameters in the prefabricated exterior wall production, until the recalculated production evaluation coefficient is greater than or equal to the evaluation threshold.
