[0004] It can be seen that the above solution has the following problems: This solution cannot trace the items that cause quality problems of components, thus unable to ensure the management efficiency of the quality of precast components of assembled buildings. Summary of the Invention

[0005] For this reason, the present invention provides a quality traceability system for precast components of assembled buildings based on blockchain, which can trace whether the quality of components meets the standard by calculating the matching ratio between the detection items and the preset items in the corresponding serial numbers, and analyze the reasons why the quality of components does not meet the standard according to the judgment results, so as to improve the management efficiency of component quality.

[0006] To achieve the above object, the present invention provides a quality traceability system for prefabricated components of prefabricated buildings based on blockchain, including:

[0007] A detection module for constructing detection information including a number of detection items based on the measured parameter information of the detected component;

[0008] An information acquisition module for acquiring image information of the serial number on the component;

[0009] An information recognition module connected to the information acquisition module for recognizing the image information to obtain preset parameter information including a number of preset items, where the preset items include preset dimension information, preset quality information, preset roughness information, preset defect information, preset strength information, preset raw material information, preset transportation information, and preset storage information of the component;

[0010] A judgment module connected to the information recognition module and the detection module for sequentially judging whether each of the detection items matches the corresponding preset item;

[0011] A calculation module connected to the judgment module for calculating a matching item ratio for the component based on the judgment result of the judgment module;

[0012] An analysis module connected to the calculation module for determining whether the quality of the traced component meets the standard based on the matching item ratio, and analyzing the reason why the quality of the component does not meet the standard according to the judgment result;

[0013] An adjustment module connected to the analysis module for determining preparation parameters, storage parameters, or transportation parameters for subsequent components based on the reason.

[0014] Further, the analysis module is further configured to determine whether the quality of the component meets the standard based on the matching item ratio, and analyze the reason why the quality of the component does not meet the standard based on the variance of the historical matching item ratios, or based on the time difference between the traceability time node and the time node when the obtained component is completed in preparation, where the matching item ratio is the ratio of the number of detection items that match the corresponding preset item to the total number of detection items.

[0015] Further, the analysis module is further configured to generate corresponding processing methods based on the comparison result between the variance of each of the historical matching item ratios of the same type of components and the corresponding preset variance, including determining the corresponding parameters in the preparation process of the component, or analyzing the reason why the quality of the component does not meet the standard according to the time difference; where for a single historical matching item ratio, it is the ratio of the number of detection items that match the corresponding preset item to the total number of detection items in the corresponding historical matching information.

[0016] Further, the analysis module is further configured to determine corresponding parameters for the component preparation process based on the mismatch frequencies of the respective items, including re-determining corresponding parameters for the component preparation process based on the item types, or determining the recognition parameters of the information acquisition module for the serial number; wherein, for the mismatch frequency of a single item information, it is the number of historical matching information in which the item information in this item does not match the preset item.

[0017] Further, the recognition parameter is the resolution at which the information acquisition module acquires the image information; the analysis module is further configured to increase the resolution based on the difference between the corresponding preset ratio and the average matching item ratio, and there is a proportional relationship between the difference and the increase amplitude of the resolution; wherein, the average matching item ratio is the average value of the historical matching item ratios.

[0018] Further, the analysis module is further configured to re-determine the corresponding parameters for the component based on the reasons why the quality of the component does not meet the standard determined according to the time difference, including corresponding parameters for the component preparation process, the transportation parameters for the component, or the storage parameters for the component.

[0019] Further, the preset storage information includes storage humidity and storage temperature; the analysis module is further configured to increase the placement interval standard of each component during storage based on the storage humidity, and there is a proportional relationship between the storage humidity and the increase amplitude of the placement interval standard.

[0020] Further, the analysis module is further configured to, based on the statistically obtained mismatch frequencies of the respective item information, and based on the statistical result, record the item information with a mismatch frequency exceeding the preset frequency as abnormal item information.

[0021] Further, the detection items include dimension information, quality information, roughness information, defect information, and strength information; the analysis module is further configured to re-determine the corresponding parameters for the component preparation process according to the types of the abnormal item information, wherein:

[0022] When the type of the abnormal item information is the dimension information or the quality information, a raw material addition amount adjustment notice is issued;

[0023] When the type of the abnormal item information is the roughness information or the defect information, a raw material ratio correction notice is issued;

[0024] When the abnormal item information type is the strength information, the number of steel bars built in during the preparation of the component is increased based on the strength difference, and the strength difference is proportional to the increase amplitude of the number of steel bars; wherein, the strength difference is the difference between the preset strength and the actual strength detected by the detection module.

[0025] Further, when the type of the item information exceeding the preset frequency is the transportation information, the analysis module is further configured to increase the transportation speed based on the difference between the actual time difference and the preset time difference, and the difference is inversely proportional to the increase amplitude of the transportation speed.

[0026] Compared with the prior art, the beneficial effect of a quality traceability system for prefabricated components of an assembled building based on blockchain of the present invention is that, by setting a calculation module, the present invention can quickly complete the quality inspection of the current component by calculating the matching situation of the detected information read and the items in the preset parameter information. At the same time, by setting an analysis module, the reason for the component quality to meet the standard can be initially determined based on the actual matching result, and a corresponding processing method can be generated through the determined reason, which can effectively avoid the influence on the component itself during the subsequent preparation, storage or transportation of the component. While effectively ensuring the component quality, the management efficiency of the quality of the prefabricated components of the assembled building of the system of the present invention is effectively improved; at the same time, the system of the present invention can also adjust the recognition parameters of the information acquisition module for the serial number according to the determined reason, so as to effectively avoid the deviation of the recognized information due to improper recognition parameters while effectively avoiding the occurrence of misjudgment of the component quality. While effectively improving the recognition accuracy of the component quality, the management efficiency of the quality of the prefabricated components of the assembled building of the system of the present invention is further improved.

[0027] Further, the present invention also determines whether the quality of the component meets the standard based on the matching item ratio, and thus can more quickly determine whether the quality of the component meets the standard, and analyze the reason why the component quality does not meet the standard through the variance of the historical matching item ratio or the time difference between the traceability time node and the time node when the obtained component is completed, so that the analysis result is more accurate, so as to further improve the efficiency of component quality management.

[0028] Furthermore, when the present invention further makes a secondary judgment based on the variance of the historical matching item ratios of the same type of components, it can more accurately determine the corresponding parameters in the subsequent preparation process for the reasons why the quality of the components does not meet the standards, thereby further avoiding the impact on the quality of the components themselves during the preparation process. By calculating the variance of the historical matching item ratios for the same type of components, it can further avoid errors in judging the reasons for the non-compliance of component quality due to the use of the same preset variance for different types of components, thereby further improving the accuracy of the reasons for the non-compliance of component quality and further enhancing the efficiency of component quality management.

[0029] Furthermore, the present invention also determines the corresponding parameters in the preparation process or the identification parameters of the serial number based on the item types in the mismatch frequencies of each item, so that the corresponding parameters can be adjusted more precisely for the item types, and further improve the efficiency of component quality management.

[0030] Furthermore, the present invention also increases the resolution based on the difference between the first preset ratio and the average matching item ratio, so as to more accurately adjust the identification parameters of the serial number, thereby further avoiding the situation of misjudgment of whether the quality of the components meets the standards due to improper setting of the identification parameters of the serial number in the information acquisition module, and further improving the efficiency of component quality management.

[0031] Furthermore, the present invention also re-determines the parameters in the preparation process, or the transportation parameters, or the storage parameters based on the magnitude relationship between the time difference and the first preset time difference, so as to more accurately determine the values of the corresponding parameters, and more effectively avoid the impact on the components themselves during the subsequent preparation, storage, or transportation of the components. While effectively ensuring the quality of the components, it further improves the efficiency of component quality management.

[0032] Furthermore, the present invention also increases the placement interval of the components based on the relationship between the storage humidity and the placement interval standard of each component during storage, so as to more accurately determine the placement interval standard of the components, and more effectively avoid the impact on the quality of the components caused by the storage process, so as to further improve the efficiency of component quality management.

[0033] Furthermore, the present invention is also used to count the mismatch frequencies of each item information, mark the item information that exceeds the preset frequency, and mark it as abnormal item information, so as to more effectively count the items that cause the non-compliance of component quality, so that subsequent adjustments can be made more quickly for the abnormal item information, so as to further improve the efficiency of component quality management.

[0034] Furthermore, the present invention also re-determines the corresponding parameters during the component preparation process based on the types of abnormal item information, so as to more accurately adjust the corresponding parameters during the preparation process, further avoid the subsequent impact on the component itself during the preparation process, and further improve the efficiency of component quality management.

[0035] Furthermore, the present invention also increases the transportation speed based on the difference between the actual time difference and the preset time difference, so as to more accurately determine the transportation speed, further avoid the subsequent impact on the component itself during the transportation process, and further improve the efficiency of component quality management.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0044] Please refer to Figure 1 As shown, it is a schematic diagram of the modules of a quality traceability system for prefabricated components of an assembly building based on blockchain in this embodiment.

[0045] The system includes a detection module, an information acquisition module, an information recognition module, a judgment module, a calculation module, an analysis module, and an adjustment module.

[0046] The detection module is used to detect the parameter information of the component and construct detection information including several detection items based on the measured parameter information. Among them, the detection items include dimension information, quality information, roughness information, defect information, and strength information.

[0047] The information acquisition module is used to acquire the image information of the serial code on the component.

[0048] The information recognition module is connected to the information acquisition module and is used to recognize the image information to obtain preset parameter information including several preset items. Among them, the preset items include preset dimension information, preset quality information, preset roughness information, preset defect information, preset strength information, preset raw material information, preset transportation information, and preset storage information.

[0049] The judgment module is connected to the information recognition module and the detection module and is used to sequentially judge whether each detection item matches the corresponding preset item.

[0050] The calculation module is connected to the judgment module and is used to calculate the matching item ratio for the component based on the judgment result of the judgment module. Among them, the matching item ratio is the ratio of the number of detection items that match the corresponding preset items to the total number of detection items.

[0051] The analysis module is connected to the calculation module and is used to determine whether the quality of the traced component meets the standard based on the matching item ratio, and analyze the reasons why the quality of the component does not meet the standard according to the determination result.

[0052] The adjustment module is connected to the analysis module and is used to determine the preparation parameters, storage parameters or transportation parameters for subsequent components based on the reasons why the quality of the component does not meet the standard.

[0053] Specifically, in this embodiment, the detection module is used to detect the size, quality, roughness, defects and strength of the component, and construct the detection information of the detection items based on the above parameter information; then the information acquisition module acquires the image information of the serial number on each component, and the basic information of each component can be obtained; then the information recognition module scans and recognizes the image information obtained by the information acquisition module to obtain the preset parameter information of several preset items. Taking a building component as an example, the preset size information is that the width is 500 mm and the thickness is 120 mm, the preset quality information is to use sleeve grouting connection with steel bars, the preset roughness information is that the surface roughness is kept between 0.8 - 1.0 μm, the preset defect information is that there are no surface defects, the preset strength information is that the concrete strength grade of the precast component is higher than C30, the preset raw material information is cement, sand, gravel and steel bars, the preset transportation information is that the transportation method is a truck, the transportation distance is 90.6 km, the transportation duration is 2.5 hours, and the average transportation speed is 36.24 km / h. Among them, the average speed on the highway section is 70 km / h, and the average speed on the remaining sections is 40 km / h. The storage information includes a storage temperature of 10°C, a storage humidity of 50%, a storage start time of 30 days, and a storage stacking method of horizontal stacking; then the judgment module judges whether the detection items in the detection module match the corresponding preset items; then the calculation module calculates the ratio of the detection items that match the corresponding preset items to the total number of detection items based on the judgment result of the judgment module to obtain the matching item ratio; then the analysis module determines whether the quality of the traced component meets the standard based on the matching item ratio. When the matching item ratio is greater than or equal to the first preset ratio, the analysis module determines that the quality of the component meets the standard. When the matching item ratio is less than the first preset ratio and greater than the second preset ratio or when the matching item ratio is less than or equal to the second preset ratio, the analysis module analyzes the reasons why the quality of the component does not meet the standard; finally, the adjustment module adjusts the preparation parameters, storage parameters or transportation parameters of the subsequent components based on the reasons why the quality of the component analyzed by the analysis module does not meet the standard.

[0054] Please refer to Figure 2 as shown, which is a flowchart of a quality traceability system for precast components of an assembled building based on blockchain in this embodiment. The process includes:

[0055] S1: The detection module constructs detection information including several detection items based on the measured parameter information of the detected component. Among them, the detection items include size information, quality information, roughness information, defect information and strength information.

[0056] S2: Obtain the image information of the serial code on the component through the information acquisition module.

[0057] S3: Identify the image information through the information recognition module connected to the information acquisition module to obtain preset parameter information including several preset items.

[0058] S4: Sequentially determine whether each of the detection items matches the corresponding preset item through the judgment module connected to the information recognition module and the detection module respectively;

[0059] S5: Calculate the matching item ratio for the component based on the judgment result of the judgment module through the calculation module connected to the judgment module.

[0060] S6: Determine whether the quality of the traced component meets the requirements based on the matching item ratio through the analysis module connected to the calculation module, and analyze the reason why the quality of the component does not meet the standard according to the judgment result.

[0061] S7: Determine the preparation parameters, storage parameters or transportation parameters for subsequent components based on the reason through the adjustment module connected to the analysis module.

[0062] Please refer to Figure 3 As shown, it is a logic flowchart for determining whether the quality of a component meets the standard based on the matching item ratio in this embodiment. The analysis module is used to determine whether the quality of the component meets the standard based on the matching item ratio, and analyze the reason why the quality of the component does not meet the standard based on the variance of the historical matching item ratio, or based on the time difference between the tracing time node and the time node when the obtained component is completed for preparation, where the matching item ratio is the ratio of the number of detection items that match the corresponding preset item to the total number of detection items.

[0063] Specifically, in this embodiment, the matching item ratio L0 can be divided into a first preset ratio L1 and a second preset ratio L2. Among them, it is set that the first preset ratio L1 = 0.5 and L2 = 0.5 × L1 in the matching item ratio standard. It should be noted that in other embodiments, the values of L1 and L2 can also be determined according to the relative component quality requirements, and the vertical values of the matching items are rounded up; the specific process of comparing the matching item ratio L with L1 and L2 is as follows:

[0064] If the matching item ratio L is greater than or equal to the first preset ratio L1, it indicates that the number of matching items is relatively large. Therefore, it can be determined that the quality of the current component meets the standard. In the subsequent stage, the design and development of the component will continue to follow the current system configuration specifications;

[0065] If the matching item ratio L is greater than the second preset ratio L2 and less than the first preset ratio L1, it can be determined that the quality of the current component does not meet the standard. At this time, it is necessary to further determine the reason why the quality of the component does not meet the standard based on the variance P of the historical matching item ratio.

[0066] If the matching item ratio L is less than or equal to the second preset ratio L2, it can be determined that the quality of the current component does not meet the standard. At this time, it is necessary to analyze the reason why the quality of the component does not meet the standard based on the time difference Q between the traceability time node and the time node when the component is completed for preparation.

[0067] Further, the analysis module is also used to determine, based on the variance of the historical matching item ratio for the same type of component, the corresponding parameters for the component preparation process based on the mismatch frequency of each item, or to analyze the reason why the quality of the component does not meet the standard using the time difference; wherein, the mismatch frequency is the ratio of the statistic of the historical mismatch items to the total historical statistic.

[0068] Specifically, in this embodiment, the preset variance P0 = 1, and the comparison process based on the variance of the historical matching item ratio for the same type of component is as follows:

[0069] If the variance P is less than or equal to the preset variance P0, it indicates that the reason for the component's quality not meeting the standard is a problem in the component preparation process, and it is necessary to count the mismatch frequency R of each item; if the variance P is greater than the preset variance P0, it is necessary to analyze the reason for the component's quality not meeting the standard based on the time difference Q.

[0070] Please refer to Figure 4 As shown, it is a logic flowchart for determining the reason for the component's quality not meeting the standard based on the mismatch frequency of the mismatch items of each item in this embodiment. The analysis module is also used to re-determine the corresponding parameters in the preparation process based on the mismatch frequency of each item, or to determine the recognition parameters of the information acquisition module for the serial number.

[0071] Specifically, in this embodiment, the preset mismatch frequency R0 = 0.7, and the comparison process based on the mismatch frequency R and R0 is as follows:

[0072] In the case where the mismatch frequency R of a single item is greater than the preset mismatch frequency R0, it is necessary to make an adjustment for this item. The following are the specific implementation methods:

[0073] If this item is the size information of the component, a raw material quantity adjustment notice is issued; if this item is the raw material information of the component, a raw material ratio correction notice is issued.

[0074] If the item is the strength information of the component, the increase amplitude of the number of steel bars is adjusted based on the strength difference, that is, the greater the difference, the greater the increase amplitude of the steel bars. When the strength difference is greater than the preset strength difference, the number of steel bars is adjusted to 3 times the original number of steel bars. When the strength difference is less than or equal to the preset difference, the number of steel bars is adjusted to 1.6 times the original number of steel bars;

[0075] If the item is the transportation information of the component, the transportation speed is adjusted based on the difference between the actual time difference and the first preset time difference, that is, the smaller the difference, the greater the adjusted transportation speed. When the difference is less than or equal to the preset difference, the transportation speed is increased to 1.3 times the original transportation speed. When the difference is greater than the preset difference, the transportation speed is increased to 1.1 times the original transportation speed;

[0076] When the mismatch frequencies R of all items are less than or equal to the preset mismatch frequency R0, it indicates that there is a problem with the recognition parameters for the serial number. The resolution is adjusted based on the difference between the first preset ratio and the average matching item ratio, that is, the greater the difference, the greater the increase amplitude of the resolution. When the difference W is greater than the preset difference W0, the resolution is adjusted to 3 times the original resolution. When the difference W is less than or equal to the preset difference W0, the resolution is adjusted to 1.7 times the original resolution.

[0077] Please refer to Figure 5 as shown, which is a logic flowchart for analyzing the reasons why the quality of the component does not meet the standard based on the time difference Q between the traceability time node and the time node when the obtained component is completed. The analysis module is also used to re-determine the corresponding parameters, or the transportation parameters, or the storage parameters in the preparation process based on the time difference and the item type.

[0078] Specifically, in this embodiment, the preset time difference Q0 can be set to 0.5. The comparison process based on the time difference Q and Q0 is as follows:

[0079] If the time difference Q is less than or equal to the preset time difference Q0, it indicates that the quality of the current component is unqualified. It is necessary to count the unqualified items and rectify the unqualified items. In this embodiment, the size of the component is adjusted by issuing a notice to adjust the addition amount of raw materials, the strength of the component is adjusted by the number of steel bars built-in, the raw material information is adjusted by issuing a notice to correct the raw material ratio, and the transportation parameters are adjusted by the transportation speed; if the time difference Q is greater than the preset time difference Q0, it indicates that the reason for the unqualified quality of the component is the storage environment of the component. In this embodiment, the visit interval standard of each component during storage is determined based on the storage humidity, that is, the greater the storage humidity, the greater the increase amplitude of the placement interval standard. That is, when the storage humidity T is greater than the preset storage humidity T0, the increase amplitude of the placement interval standard of the component is 1.5 times the original placement interval. When the storage humidity T is less than or equal to the preset storage humidity T0, the increase amplitude of the placement interval standard of the component is 1.2 times the original placement interval.
