BIM (Building Information Modeling) technology is a data-based tool applied to engineering design, construction, and management. It integrates data-based and information-based models of buildings to share and transfer in the whole life cycle of project planning, operation, and maintenance, aiming to improve production efficiency, save costs, and shorten construction period. Smart construction site refers to the use of information technology to accurately design and simulate construction projects through a three-dimensional design platform, focusing on construction process management, and achieving full-process and full-process management of the construction site.

[0003] The existing technology constructs a BIM model by using BIM modeling software on CAD (Computer-Aided Design) construction drawings, combines the constructed BIM model with a smart construction site system, visualizes the construction simulation progress through the BIM model, and finally obtains real-time feedback and management of the construction progress data to adjust the construction progress plan.

If so, real-time inventory data is obtained and analyzed to obtain the inventory status evaluation value, thereby achieving the effect of improving the timeliness of progress tracking and control of incoming and outgoing materials in the process of smart construction site management.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] like Figure 1 As shown, it is a structural schematic diagram of the smart construction site management system based on BIM technology provided by an embodiment of the present application. The smart construction site management system based on BIM technology provided by an embodiment of the present application includes: a material acceptance module, a progress simulation module and an inventory control module; wherein the material acceptance module is used to monitor the transportation status of the materials to be entered in real time to obtain the data of the materials to be entered, and at the same time, perform material acceptance deviation analysis based on the obtained data of the materials to be entered to obtain a deviation analysis index, and the deviation analysis index is used to quantify the degree of deviation between the data of the materials to be entered and the target material data; the progress simulation module is used to determine whether to perform progress simulation based on the obtained deviation analysis index, and if so, simulate the material entry and monitor the progress changes during the material entry process in real time and compare and analyze with the actual progress to obtain a progress compliance score, and the progress compliance score is used to quantify the degree of compliance between the simulated progress of the materials to be entered and the actual progress; the inventory control module is used to determine whether to perform inventory management based on the obtained progress compliance score, and if so, obtain real-time inventory data and analyze it to obtain an inventory status evaluation value, and the inventory status evaluation value is used to evaluate the inventory management efficiency of the designated transport vehicles and designated warehouses in the construction site corresponding to the materials to be stored.

[0027] Among them, the materials to be entered are the construction site materials in the designated construction area; the materials to be entered include the first materials to be entered and the second materials to be entered; the target materials to be entered data include the target quantity of materials to be entered, the target weight of materials to be entered, the target loading time and the target transportation time; the real-time inventory data includes the first real-time inventory quantity and the second real-time inventory quantity; the first real-time inventory quantity is used to reflect the inventory status of the designated transport vehicle; the second real-time inventory quantity is used to reflect the inventory status of the designated area in the construction site warehouse.

[0028] In the embodiment, the first material to be brought in is usually a specified batch of steel bars, and the second material to be brought in is usually a specified batch of concrete, the steel bars in each batch have the same specification, and the concrete in each batch has the same weight; the transportation state is visually displayed through the built BIM model; the transportation state usually includes loading, loaded, in transit, and arrived; the data of the material to be brought in includes but is not limited to the type, weight, specification, quantity, transportation vehicle information and supplier information of the material to be brought in, and is usually obtained by directly scanning the cargo list on the corresponding transportation vehicle of the material to be brought in through a high-definition camera.

[0029] The creation process of the BIM model is as follows: data collection and sorting, including architectural design drawings, construction drawings, bill of quantities, material specifications and other related information, which need to be digitized and processed, and can be converted through scanning, shooting and other means; according to the related information obtained through data collection and sorting, the geometric model is constructed through BIM software, which can be constructed layer by layer according to the structure, layout and shape of the building, including the establishment of components such as walls, floors, beams and columns; in the process of model construction, each component needs to be assigned with corresponding attribute information, including material, size, weight, etc., which will play an important role in subsequent simulation analysis and collaborative design; in the BIM model, there are complex spatial relationships between the components of the building, through BIM software, the spatial position and mutual relationship of each component can be accurately established and adjusted, so that collaborative design and collision detection of multiple professional models in the same coordinate system can be realized.

[0030] In summary, the existing BIM model not only realizes design visualization, but also realizes the visualization of construction, device operability and collision checking. In the transportation field, the operator can intuitively view the various links of the container in transit through the BIM model, or uniformly manage and optimize the rail transit station, carriages and off-site space, so as to optimize the transportation scheme in time and improve the operation efficiency.

[0031] The present example realizes the all-round and whole-process intelligent management of site material management, progress control and inventory state evaluation through the collaborative work among the material acceptance module, the progress simulation module and the inventory control module, which enables the preset personnel to make decisions based on data, and thus improves the timeliness of the tracking and control of the material progress in the process of intelligent site management.

[0032] Further, the deviation analysis index is obtained by the following method: obtaining the actual loading time and the actual transportation time of the to-be-entering material within the preset entering period, and obtaining the loading time score and the transportation time score by combining the target loading time and the target transportation time, the loading time score representing the ratio of the absolute value of the difference between the actual loading time and the target loading time to the target loading time, and the transportation time score representing the ratio of the absolute value of the difference between the actual transportation time and the target transportation time to the target transportation time; obtaining the deviation analysis coefficient of the to-be-entering material within the preset entering period: when the to-be-entering material is the first to-be-entering material, obtaining the actual entering material quantity within the preset entering period and obtaining the material quantity score by combining the target entering material quantity, and obtaining the deviation analysis index by combining the deviation analysis parameter and the material quantity deviation weight factor in the database, the material quantity score representing the ratio of the absolute value of the difference between the actual entering material quantity and the target entering material quantity to the reference material quantity deviation; when the to-be-entering material is the second to-be-entering material, obtaining the actual entering material weight within the preset entering period and obtaining the material weight score by combining the target entering material weight, and obtaining the deviation analysis index by combining the deviation analysis parameter and the material weight deviation weight factor in the database, the material weight score representing the ratio of the absolute value of the difference between the actual entering material weight and the target entering material weight to the reference material weight deviation; the deviation analysis parameter includes the obtained loading time score, the transportation time score, and the loading time deviation weight factor and the transportation time deviation weight factor in the database.

[0033] wherein the specific limit expression of the deviation analysis index is:

[0034] ;

[0035] ;

[0036] ;

[0037] ;

[0038] ;

[0039] ;

[0040] in the formula, represents the deviation analysis index of the yth to-be-entering material within the preset entering period, represents the first to-be-entering material, represents the second to-be-entering material, represents the loading time deviation weight factor, represents the deviation analysis coefficient of the yth to-be-entering material within the preset entering period, a loading time fraction of the yth material to be received within a preset receiving period, an actual loading time of the yth material to be received within a preset receiving period, a target loading time, a transportation time deviation weight factor, a transportation time fraction of the yth material to be received within a preset receiving period, an actual transportation time of the yth material to be received within a preset receiving period, a target transportation time, a material quantity deviation weight factor, a material quantity fraction of the first material to be received within a preset receiving period, an actual receiving material quantity of the first material to be received within a preset receiving period, a target receiving material quantity of the first material to be received, a reference material quantity deviation, a material weight deviation weight factor, a material weight fraction of the second material to be received within a preset receiving period, an actual receiving material weight of the second material to be received within a preset receiving period, a target receiving material weight of the second material to be received, a reference material weight deviation.

[0041] In the embodiment, the target loading time, the target transportation time, the target receiving material quantity and the target receiving material weight are set by the construction manager, the reference material quantity deviation is represented by the result of summing and averaging the historical material quantity deviations of the first material to be received within each receiving period in the database, and the reference material weight deviation is represented by the result of summing and averaging the historical material weight deviations of the second material to be received within each receiving period in the database.

[0042] The loading time deviation weight factor and the transportation time deviation weight factor respectively represent the influence degree of the preset loading time deviation and the preset transportation time deviation in the database on the deviation analysis index acquisition process. Specifically, the database stores preset weight factors corresponding to the deviation analysis index, and there is a pre-set mapping relationship between the weight factors and the deviation analysis index. The mapping relationship can be one-to-one or many-to-one. In actual application, the real-time loading time deviation and the transportation time deviation can be input into the mapping relationship, so as to quickly obtain the corresponding weight factors, which provides an important quantitative index for evaluating the accuracy and reliability of the material acceptance deviation analysis, and further more accurately calculates the deviation analysis index.

[0043] The material quantity deviation weight factor and material weight deviation weight factor represent the degree of influence of the material quantity deviation and material weight deviation, respectively, pre-set in the database, on the process of obtaining the deviation analysis index. Specifically, the database stores preset weight factors corresponding to the deviation analysis index. There is a pre-set mapping relationship between these weight factors and the deviation analysis index. This mapping relationship can be one-to-one or many-to-one. In practical applications, real-time material quantity deviation and material weight deviation can be input into this mapping relationship to quickly obtain the corresponding weight factors. This provides an important quantitative indicator for evaluating the accuracy and reliability of material acceptance deviation analysis, thereby more accurately calculating the deviation analysis index.

[0044] Among them, the loading time deviation represents the absolute value of the difference between the actual loading time and the target loading time, the transportation time deviation represents the absolute value of the difference between the actual transportation time and the target transportation time; the material quantity deviation represents the absolute value of the difference between the actual quantity of incoming materials and the target quantity of incoming materials, and the material weight deviation represents the absolute value of the difference between the actual weight of incoming materials and the target weight of incoming materials.

[0045] In this example, the value ranges of the loading time deviation weight factor, transportation time deviation weight factor, material quantity deviation weight factor, and material weight deviation weight factor are all limited to between 0 and 1. When , the sum of the loading time deviation weight factor, transportation time deviation weight factor and material quantity deviation weight factor in this example is 1; when In this example, the sum of the loading time deviation weight factor, transportation time deviation weight factor, and material weight deviation weight factor is 1.

[0046] The aforementioned database is a database established before the design of the smart construction site management system based on BIM technology for storing various types of setting data. The database includes but is not limited to preset deviation analysis indexes, preset progress compliance scores, preset inventory status assessment values, and preset entry time periods and progress simulation time periods. The various values ​​are directly set by technical personnel. The setting basis of the preset deviation analysis index can be determined according to the actual material acceptance scenario of each material to be entered. For example, the preset deviation analysis index is represented by the sum and average of the historical deviation analysis indexes of each material to be entered in the database during each entry time period. In addition, the various values ​​in the database can be set and fine-tuned by technical personnel according to actual debugging.

[0047] It is important to understand that when When , the deviation analysis index increases with the increase of loading time score, transportation time score and material quantity score. When the deviation analysis index is greater than the preset deviation analysis index, the deviation analysis index increases with the increase of the loading time score, the transportation time score and the material weight score, wherein the loading time score increases with the increase of the loading time deviation, the transportation time score increases with the increase of the transportation time deviation, the material quantity score increases with the increase of the material quantity deviation, and the material weight score increases with the increase of the material weight deviation.

[0048] It should be noted that when The material quantity score also indirectly affects the value of the loading time score. When the quantity of the material increases, the loading operation becomes more complex and time-consuming, because more time is needed to accurately count, classify, stack and fix the material to ensure safety and stability during transportation. Therefore, the increase of the material quantity score is often accompanied by the increase of the loading time score, because more time is needed to handle the difference in quantity.

[0049] When The material weight score also indirectly affects the value of the loading time score. When the weight of the material increases, heavy materials require more strength and skill to carry and stack, which increases the difficulty and time of loading. Therefore, the increase of the material weight score indirectly increases the value of the loading time score.

[0050] By considering the indirect influence mechanism of the material quantity score and the material weight score on the loading time score, it is helpful to more accurately evaluate various factors in the process of material entering and leaving the site, so as to develop more effective management strategies, thereby realizing the improvement of the timeliness of the progress tracking and control of the material entering and leaving the site in the process of smart construction site management, effectively solving the problem of low timeliness of the progress tracking and control of the material entering and leaving the site in the process of smart construction site management in the prior art.

[0051] Further, the specific process of determining whether to perform progress simulation according to the obtained deviation analysis index is: determining whether the obtained deviation analysis index is less than the preset deviation analysis index in the database: if the obtained deviation analysis index is less than the preset deviation analysis index in the database, completing the material acceptance deviation analysis and recording the to-be-entered material corresponding to the completed material acceptance deviation analysis as an entered material, and simultaneously monitoring the simulation progress of the to-be-entered material in the progress simulation process; if the obtained deviation analysis index is not less than the preset deviation analysis index in the database, sending a material acceptance warning instruction and re-performing material acceptance deviation analysis; the entered material includes a first entered material and a second entered material; the progress simulation process includes a first entered material progress simulation process and a second entered material progress simulation process; the material acceptance warning instruction is used to prompt a preset person to check the material acceptance process.

[0052] In the embodiment, the simulation progress in the progress simulation process generally refers to the material acceptance process and the corresponding sequence, i.e., arrival inspection, sampling detection, record and check, and warehouse management. The example can more accurately evaluate the arrival situation and progress compliance degree of the to-be-arrived material by monitoring the simulation progress of the to-be-arrived material in the progress simulation process in real time and comparing with the actual progress. The accuracy helps the manager to find the progress delay or deviation in time, and enhances the risk management capability.

[0053] Further, the specific obtaining step of the progress compliance score is: when the obtained deviation analysis index is less than the preset deviation analysis index in the database, obtaining a first material sorting time length score and a second material transfer time length score at the end of the progress simulation period, the first material sorting time length score representing a ratio of the first material sorting time length to the total time length of the progress simulation period, and the second material transfer time length score representing a ratio of the second material transfer time length to the total time length of the progress simulation period; obtaining a first material arrival time deviation and a second material arrival time deviation at the end of the progress simulation period, and obtaining a progress compliance score by combining the obtained deviation analysis index and the maximum allowed material arrival time deviation in the database and the progress compliance weight factor, the first material arrival time deviation representing a time difference between the time of the first to-be-arrived material arriving at the designated place and the target arrival time, and the second material arrival time deviation representing a time difference between the time of the second to-be-arrived material arriving at the designated place and the target arrival time.

[0054] When the obtained deviation analysis index is less than the preset deviation analysis index in the database, the specific limit expression of the progress compliance score is:

[0055] ;

[0056] In the formula, e is a natural constant, represents the progress compliance score of the to-be-arrived material in the progress simulation process, represents the deviation analysis index weight factor, represents the deviation analysis index of the to-be-arrived material in the preset arrival period, One represents the deviation analysis index of the to-be-arrived material in the preset arrival period, represents the deviation analysis index of the to-be-arrived material in the preset arrival period, Two represents the deviation analysis index of the to-be-arrived material in the preset arrival period, represents the material delay time length weight factor, represents the first material sorting time length score of the first to-be-arrived material at the end of the progress simulation period, represents the second material transfer time length score of the second to-be-arrived material at the end of the progress simulation period, represents the material arrival time deviation weight factor, a first material arrival time deviation of the first incoming material at the end of the progress simulation period, a second material arrival time deviation of the second incoming material at the end of the progress simulation period, a maximum allowed material arrival time deviation.

[0057] In the embodiment, the total length of the progress simulation period and the target arrival time are set by the construction manager, and the maximum allowed material arrival time deviation represents the maximum value of the material arrival time deviation of the incoming material in the database at the end of each progress simulation period.

[0058] The preset weight factors closely related to the progress compliance score are stored in the database, and the weight factors establish a predefined mapping relationship with the corresponding deviation analysis index, material delay time length score and material arrival time deviation. It is worth noting that this mapping is not randomly set, and it can be one-to-one or many-to-one relationship. In actual application, when the progress compliance of the incoming material in the progress simulation process needs to be evaluated, the deviation analysis index, material delay time length score and material arrival time deviation obtained in real time can be directly input into the preset mapping relationship, so that the deviation analysis index weight factor, material delay time length weight factor and material arrival time deviation weight factor corresponding to the progress compliance score can be quickly and accurately obtained.

[0059] In the formula, the material delay time length score is the sum of the first material sorting time length score and the second material transfer time length score, and the material arrival time deviation is the sum of the first material arrival time deviation and the second material arrival time deviation. It is particularly important to ensure the consistency and comparability of the evaluation that the value range of the deviation analysis index weight factor, the material delay time length weight factor and the material arrival time deviation weight factor is strictly limited to 0 to 1, and the sum of the three is 1.

[0060] Specifically, When the maximum allowed material arrival time deviation is 5 min, the change statistical table of the progress compliance score is shown in Table 1:

[0061] Table 1 Change statistical table of progress compliance score

[0062]

[0063] It should be understood that from Table 1, the progress compliance score decreases with the increase of the deviation analysis index, the first material sorting time length score, the second material transfer time length score, the first material arrival time deviation and the second material arrival time deviation.

[0064] It should be noted that the deviation analysis index affects the value of the first material arrival time deviation by affecting the value of the first material sorting time score. When the deviation analysis index increases, it means that the deviation of the sorting process of the material may increase, which may lead to a decrease in the first material sorting time score, because the sorting process is disturbed or delayed, that is, the extension of the first material sorting time will directly lead to the increase of the first material arrival time deviation. Therefore, the deviation analysis index indirectly affects the first material arrival time deviation by affecting the first material sorting time score.

[0065] The second material transfer time score also indirectly affects the value of the second material arrival time deviation. When the second material transfer time score decreases, it means that the transfer process of the second incoming material may be delayed, which reduces the transfer efficiency. The reduction of the transfer efficiency will directly lead to the increase of the second material arrival time deviation. Therefore, the second material transfer time score directly reflects the efficiency of the transfer process, and further affects the second material arrival time deviation.

[0066] By considering the above indirect influence mechanism, it can be more comprehensively understood how each link in the material progress tracking and control is related to each other. This understanding helps to more accurately predict and evaluate the actual situation of the material progress, so as to develop more effective control strategies, and thus realizes the improvement of the timeliness of the progress tracking and control of the incoming and outgoing materials in the intelligent construction site management process, effectively solving the problem of low timeliness of the progress tracking and control of the incoming and outgoing materials in the intelligent construction site management process in the prior art.

[0067] Further, the specific process of determining whether to perform inventory management according to the obtained progress compliance score is: determining whether the obtained progress compliance score is greater than the preset progress compliance score in the database: if the obtained progress compliance score is greater than the preset progress compliance score in the database, completing the progress simulation and recording the incoming material corresponding to the completed progress simulation as a to-be-stored material, and simultaneously monitoring the storage state of the to-be-stored material in the inventory management process; if the obtained progress compliance score is not greater than the preset progress compliance score in the database, sending a progress simulation warning instruction and an instruction to re-perform the progress simulation; the to-be-stored material includes a first to-be-stored material and a second to-be-stored material; the inventory management includes inventory management of a specified transport vehicle and inventory management of a specified warehouse in the construction site; the progress simulation warning instruction is used to prompt a preset person to check the progress simulation process.

[0068] In the embodiment, the preset progress compliance score is represented by the result of summing and averaging the historical progress simulation scores of each incoming material in the database in the historical progress simulation process; the present example can accurately judge whether the actual situation of the current material progress meets the expectation by comparing the obtained progress compliance score with the preset progress compliance score in the database, and secondly, the inventory management in the present example not only includes the inventory management of the specified transport vehicle, but also covers the inventory management of the specified warehouse in the construction site, realizing the whole-chain management of the materials. The comprehensive management mode ensures the safety and controllability of the materials in the transportation and storage process.

[0069] Further, the inventory state evaluation value is obtained by the following method: when the obtained progress compliance score is greater than the preset progress compliance score in the database and the current inventory management time is not equal to 1: obtaining a vehicle inventory turnover rate, the vehicle inventory turnover rate being the sum of a first vehicle inventory turnover rate and a second vehicle inventory turnover rate, the first vehicle inventory turnover rate representing the ratio of the absolute value of the difference between the first to-be-stored material quantity of the specified transport vehicle at the current inventory management time and the first to-be-stored material quantity at the last inventory management time to the initial first to-be-stored material quantity, and the second vehicle inventory turnover rate representing the ratio of the absolute value of the difference between the second to-be-stored material weight of the specified transport vehicle at the current inventory management time and the second to-be-stored material weight at the last inventory management time to the initial second to-be-stored material weight; obtaining a warehouse inventory turnover rate, the warehouse inventory turnover rate being the sum of a first warehouse inventory turnover rate and a second warehouse inventory turnover rate, the first warehouse inventory turnover rate representing the ratio of the absolute value of the difference between the first to-be-stored material quantity of the specified warehouse at the current inventory management time and the first to-be-stored material quantity at the last inventory management time to the initial first to-be-stored material quantity, and the second warehouse inventory turnover rate representing the ratio of the absolute value of the difference between the second to-be-stored material weight of the specified warehouse at the current inventory management time and the second to-be-stored material weight at the last inventory management time to the initial second to-be-stored material weight; obtaining an inventory state factor and obtaining an inventory state evaluation value by combining the obtained vehicle inventory turnover rate, warehouse inventory turnover rate, and progress compliance score, the inventory state factor including a first inventory state factor and a second inventory state factor, the first inventory state factor being used for visualizing the inventory state of the specified transport vehicle, and the second inventory state factor being used for visualizing the inventory state of the specified warehouse.

[0079] In this embodiment, the initial first to-be-stored material quantity of the first to-be-stored material in the specified transport vehicle, the initial second to-be-stored material weight of the second to-be-stored material in the specified transport vehicle, the initial first to-be-stored material quantity of the first to-be-stored material in the specified warehouse, and the initial first to-be-stored material weight of the second to-be-stored material in the specified warehouse are all not equal to 0.

[0080] The first inventory state factor usually takes 0, 0.5 and 1, is monitored in real time by a high-definition camera deployed inside the specified transport vehicle and sends corresponding instructions through the sensor in the high-definition camera, usually including no inventory amount instruction, not full inventory amount instruction and full inventory amount instruction, when receiving the no inventory amount instruction, it indicates that the specified transport vehicle has no to-be-stored material at the current inventory management time, and the corresponding first inventory state factor is recorded as 0, when receiving the not full inventory amount instruction, it indicates that the to-be-stored material in the specified transport vehicle is not full at the current inventory management time, and the corresponding first inventory state factor is recorded as 0.5, when receiving the full inventory amount instruction, it indicates that the to-be-stored material in the specified transport vehicle is full at the current inventory management time, and the corresponding first inventory state factor is recorded as 1.

[0081] The second inventory state factor usually takes 0 and 1, is monitored in real time by a high-definition camera deployed inside the specified warehouse and sends corresponding instructions through the sensor in the high-definition camera, usually including replenishment material instruction and continue monitoring instruction, when receiving the replenishment material instruction, it indicates that the specified warehouse needs to replenish to-be-stored material at the current inventory management time, and the corresponding second inventory state factor is recorded as 0, when receiving the continue monitoring instruction, it indicates that the specified warehouse does not need to replenish to-be-stored material at the current inventory management time, and the corresponding second inventory state factor is recorded as 1.

[0082] It needs to be understood that the inventory state evaluation value increases with the increase of the progress compliance score, and decreases with the increase of the vehicle inventory turnover rate and the warehouse inventory turnover rate, when At this time, the first vehicle inventory turnover rate increases as the first quantity deviation of the material to be stored in the designated transport vehicle (i.e. ) increases, the second vehicle inventory turnover rate increases as the second quantity deviation of the material to be stored in the designated transport vehicle (i.e. ) increases, the first warehouse inventory turnover rate increases as the first quantity deviation of the material to be stored in the designated warehouse (i.e. ) increases, and the second warehouse inventory turnover rate increases as the second quantity deviation of the material to be stored in the designated warehouse (i.e. ) increases.

[0083] It should be noted that the progress compliance score also indirectly affects the values of the vehicle inventory turnover rate and the warehouse inventory turnover rate. When the progress compliance score increases, it means that the actual progress is more consistent with the planned progress, which indicates that the use and transportation of the material to be stored are proceeding as expected. In this case, the inventory turnover rates of the vehicles and warehouses also increase accordingly, because the material to be stored can be timely in and out according to the plan, reducing the time of accumulation and waiting, which helps to plan and arrange the transportation and storage of materials in advance, that is, efficient scheduling and coordination help to improve the operation efficiency of vehicles and warehouses, thereby improving the vehicle inventory turnover rate and the warehouse inventory turnover rate.

[0085] Further, the real-time inventory data is obtained and analyzed to obtain an inventory state evaluation value, and then whether the inventory management is completed is determined based on the obtained inventory state evaluation value. The specific process is as follows: whether the obtained inventory state evaluation value is greater than a preset inventory state evaluation value in a database is determined; if the obtained inventory state evaluation value is greater than the preset inventory state evaluation value in the database, the inventory management is completed, and the material to be stored corresponding to the completed inventory management is recorded as a material to be out of the site; if the obtained inventory state evaluation value is not greater than the preset inventory state evaluation value in the database, the material to be stored corresponding to the uncompleted inventory management is recorded as a material that cannot be out of the site, and an inventory management warning instruction and an instruction to re-perform inventory management are sent; the inventory management warning instruction is used to prompt a preset person to check the inventory management process.
