Description

Technical Field

[0001] The present invention belongs to the technical field of smart construction sites, and specifically relates to a smart material management method and system. Background Art

[0002] In current smart construction site management, material management systems typically rely on traditional inventory management and simple barcode or QR code identification to track the status and usage of construction materials. The main solutions in existing technologies include the following aspects: Basic information registration: Record basic information of building materials, such as name, specification, quantity, etc., by manual entry or scanning of QR codes.

[0003] Inventory management: The warehouse management system (WMS) is used to store, ship and count construction materials, but there is a lack of effective tracking of the number of times the materials are recycled.

[0004] Condition monitoring: Some systems can update the usage status of materials in real time, but fail to fully incorporate the maximum number of material cycles for effective resource optimization.

[0005] Scrap processing: When materials reach the end of their service life, the system will mark them as scrapped, but there is no detailed residual value assessment mechanism, resulting in waste of resources.

[0006] Existing material management systems are inadequate for the efficient recycling and tracking of recyclable construction materials. Specifically, they are unable to accurately calculate and record the maximum number of times building materials can be recycled, and lack the ability to dynamically adjust and optimize resource allocation. This results in low resource utilization, increased construction costs, and unnecessary waste. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 This is a flow chart of a smart material management method of the present invention; Figure 2 This is a block diagram of a smart material management system of the present invention. DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] This invention provides an intelligent material management method that achieves efficient management and tracking of construction materials from registration to final disposal, significantly improving the optimal allocation and recycling efficiency of resources, and reducing construction costs and resource waste. The details are as follows: like Figure 1 As shown, a smart material management method in this embodiment includes the following steps: Step 1: Basic information and initial status of registration materials; specifically including: Obtain the material's identification number, X, to ensure accurate identification and tracking of each material in subsequent operations. Based on this identification number, measure and record the material's dimensions (L), width (W), height (H), and type (T), and calculate its volume (V) as L*W*H. For example, if a building material has a length (L) of 2 meters, a width (W) of 1 meter, and a height (H) of 0.5 meters, its volume (V) is 2*1*0.5 = 1 cubic meter. Calculating the material's volume provides key parameters for subsequently estimating its base value.

[0023] Based on the material type T and volume V, the base value of the material is estimated as BV = V * UPV, where UPV is the preset unit volume value; this value is updated regularly based on market conditions and reflects the market value of different types of materials. For example, if the volume V of a building material is 1 cubic meter and the unit volume value UPV for this type of material is 100 yuan / cubic meter, its base value BV = 1 * 100 = 100 yuan. By combining the material's volume and unit volume value, the base value of the material is estimated, providing a basis for subsequent assessment of the material's residual value and determining its disposal method.

[0024] The identification number X, size L, width W, height H, type T, volume V and basic value BV are entered into the database to complete the registration of basic information and initial status, ensure the integrity and accuracy of the data, and facilitate subsequent management and tracking.

[0025] Step 2: Based on the basic information, calculate and record the maximum number of recycling times of the material; specifically including: Obtain the basic value (BV) and type (T) of the material, and determine the material durability coefficient (D) based on the material type (T); the basic value (BV) reflects the initial market value of the material, while the type (T) determines its physical and chemical properties, which in turn affect its durability.

[0026] Based on the base value (BV) and the durability coefficient (D), the maximum number of cycles (MCU) is calculated as BV / D. This maximum number of cycles is associated with the identification number (X) and recorded in the database. Assuming that a building material type (T) is "reinforced concrete," its durability coefficient (D) is 0.8. Determining the material's durability coefficient (D) provides a key parameter for the subsequent calculation of the maximum number of cycles (MCU), ensuring the accuracy of the assessment results.

[0027] Based on the maximum number of cycles (MCU), the potential reuse rate of the material throughout its life cycle is assessed and marked in the material's initial state record, allowing the system to fully understand the recyclability potential of each material. This marking facilitates subsequent resource optimization and reuse decisions.

[0028] Step 3: assigning an identification code to the material according to the maximum number of recycling uses and storing it in a database; specifically comprising: Obtain the material's maximum number of cycles (MCU) and identification number (X). Based on the maximum number of cycles (MCU), determine the dynamic coefficient (DC). The dynamic coefficient (DC) is determined by the maximum number of cycles (MCU) and is calculated using the formula DC = 1 + 0.1 * MCU. The dynamic coefficient (DC) is a factor determined based on the material's maximum number of cycles (MCU) to increase the uniqueness and distinction of the identification code. The formula DC = 1 + 0.1 * MCU indicates that the dynamic coefficient equals 1 plus the maximum number of cycles multiplied by 0.1.

[0029] Assuming the maximum number of MCU cycles for a building material is 125, its dynamic coefficient DC = 1 + 0.1 * 125 = 13.5. By calculating the dynamic coefficient DC, the identification code not only relies on the material's identity number X but also incorporates the material's maximum number of cycles, increasing the uniqueness of the identification code and improving management accuracy.

[0030] The dynamic coefficient DC and the identification number X are used to generate an identification code ID using the formula ID = INT(X + DC). This ensures that each material has a unique identification code, facilitating subsequent management and tracking. For example, if the identification number X of a building material is 12345 and the dynamic coefficient DC is 13.5, its identification code ID = INT(12345 + 13.5) = 12358. By generating a unique identification code ID, each material is uniquely identified in the system, facilitating subsequent usage status updates, monitoring, and reuse decisions.

[0031] The identification code ID and all relevant information of the material, including the maximum number of cycles MCU, basic value BV, and type T, are recorded in the database. This information provides solid data support for subsequent resource optimization, usage status updates, and reuse decisions.

[0032] Step 4: Whenever the material is used, update the usage count in the database and mark the current status of the material; specifically including: Obtain the material's identification code ID and current usage count CU. The identification code ID ensures the uniqueness of each material, while the current usage count CU is used to track the actual usage of the material.

[0033] Based on the identification code ID, all relevant information about the material (such as the maximum number of cycles, MCU, base value, BV, type, etc.) is retrieved from the database. This ensures complete information when updating usage counts and status, thereby improving management accuracy. Each time a material is used, the current usage count is incremented using the formula: New CU = CU + 1. This helps accurately record the material's usage frequency. For example, if a building material has a current usage count of 5 times, when it is used again, the new usage count is New CU = 5 + 1 = 6 times. By incrementing the current usage count, the system accurately records the material's actual usage, facilitating subsequent management and decision-making.

[0034] Calculate the remaining usable count (RCU) of a material using MCU minus the new CU. Assuming a building material has a maximum reusable count (MCU) of 125 and a current usage count (new CU) of 6, its remaining usable count (RCU) equals 125 minus 6, which is 119. By calculating the remaining usable count, the system can understand the material's remaining useful life in real time, providing a basis for subsequent status marking and management. Based on the remaining usable count (RCU), the material's current status is marked. If the remaining usable count is greater than zero, it is marked as "in use"; otherwise, it is marked as "pending evaluation." This status marking facilitates subsequent resource optimization and reuse decisions. Assuming a building material has a remaining usable count (RCU) of 119, it is marked as "in use"; if the remaining usable count is 0, it is marked as "pending evaluation."

[0035] The new usage count (CU) and current status are updated in the record associated with the identification code ID in the database to ensure that the data in the system is always up to date and accurate.

[0036] Step 5: Based on the current status, check whether the maximum number of cycles has been reached. If not, continue monitoring until it is reached. Specifically, the steps include: The system obtains the material's identification code ID, current usage count (New CU), and maximum cycle usage count (MCU). Based on this ID, the system retrieves the material's current status (e.g., "in use" or "pending evaluation") from the database, ensuring that the system can make appropriate decisions and management operations based on the material's actual usage. The remaining usable count (RCU) is calculated as MCU - New CU, meaning the number of times a material can still be used is calculated by subtracting the current usage count. For example, if the maximum cycle usage count (MCU) of a building material is 125 and the current usage count (New CU) is 6, then its remaining usable count (RCU) = 125 - 6 = 119. By calculating the remaining usable count, the system can understand the material's remaining service life in real time, providing a basis for subsequent status marking and management.

[0037] Check the current status. If it's marked as in use and the remaining number of uses is greater than zero, set the monitoring cycle T = 1 / RCU, indicating a status check at regular intervals. This formula helps the system dynamically adjust the monitoring frequency, ensuring more frequent monitoring of high-use materials. For example, if the remaining number of uses (RCU) for a building material is 119, then its monitoring cycle T = 1 / 119 ≈ 0.0084 (units of time). This means the system will perform a status check approximately every 0.0084 units of time.

[0038] At the end of each monitoring cycle, the current usage count of the material is obtained again, and the remaining usable count RCU=MCU-new CU is updated until the remaining usable count is equal to zero. When the remaining usable count is equal to zero, the system automatically updates the current status of the material to "pending evaluation" and records it in the database.

[0039] Step 6: Once the maximum number of recycling times is reached, assess the residual value of the material and record the assessment results; specifically, include: Obtain the material's identification code, maximum number of cycles (MCU), and current number of cycles (new CU). Verify that the current number of cycles equals the maximum number of cycles. If this is the case, the material requires residual value assessment. For example, suppose the identification code of a building material is 12358, the maximum number of cycles (MCU) is 125, and the current number of cycles (new CU) is 125.

[0040] Based on the material's identification code (ID), the system retrieves the material's base value (BV), type (T), and historical usage history from the database and calculates the material's depreciation rate (DR) = New CU / MCU. This represents the material's depreciation calculated by dividing its current usage by its maximum number of cycles. This helps quantify the material's value loss. For example, if a building material's current usage (New CU) is 125 and its maximum number of cycles (MCU) is 125, its depreciation rate (DR) = 125 / 125 = 1. By calculating the depreciation rate, the system can quantify the material's value loss and provide a basis for subsequent residual value assessment.

[0041] Based on the depreciation rate, the residual value (RV) of the material is assessed as BV*(1-DR). This represents the calculation of the material's residual value by multiplying the base value by (1 minus the depreciation rate). This helps assess the material's actual value at the end of its lifecycle. The residual value (RV) is recorded in the database along with the material's type (T), condition, and other relevant information. By calculating the residual value, the system can determine the material's actual value at the end of its lifecycle, providing a basis for subsequent resource optimization and reuse decisions.

[0042] Mark the status of the material as "assessed" and store the assessment results in association with the identification code ID to ensure that the system can accurately track the assessment status of each material, facilitating subsequent management and decision-making.

[0043] Step 7: Based on the assessment results, decide on the material's reuse or disposal method; specifically, including: The system obtains the material's identification code ID, residual value RV, and type T. Based on the residual value RV, it determines a reuse threshold RT = BV * 0.2. This threshold is determined by multiplying the material's base value by 0.2. This threshold is used to determine whether the material has sufficient residual value for reuse. For example, if the base value BV of a building material is 100 yuan, its reuse threshold RT = 100 * 0.2 = 20 yuan. By calculating the reuse threshold, the system can set a standard for determining whether a material is worth reusing, thereby improving resource reuse.

[0044] By comparing the residual value (RV) with the reuse threshold (RT), if the residual value is greater than the reuse threshold, the material is marked as "suitable for reuse." This marking helps in subsequent resource optimization and reuse decisions. For example, if the residual value (RV) of a building material is 30 yuan and the reuse threshold (RT) is 20 yuan, the material is marked as "suitable for reuse." For materials marked as suitable for reuse, the estimated reuse cost (RC) is calculated as BV*0.1 and compared with the residual value, which means estimating the additional cost required for reuse by multiplying the base value of the material by 0.1. This helps assess the practical feasibility of reuse.

[0045] Assuming the base value (BV) of a building material is 100 yuan, its estimated reuse cost (RC) = 100*0.1 = 10 yuan. By calculating the estimated reuse cost, the system can evaluate the actual cost of reuse and compare it with the residual value to determine the economic feasibility of reuse. If the residual value is higher than the estimated reuse cost, the material's status is updated to "Recommended for Reuse" and recorded in the database. This status mark facilitates subsequent resource management and reuse operations. For example, if the residual value (RV) of a building material is 30 yuan and the estimated reuse cost (RC) is 10 yuan, the material's status is updated to "Recommended for Reuse."

[0046] If the residual value (RV) falls below the reuse threshold, or if it exceeds the reuse cost but is unsuitable for reuse, the material's status is updated to "Scrap Recommended," and the final disposal recommendation is recorded in the database. This status marking facilitates subsequent resource management and disposal decisions. For example, if the residual value (RV) of a construction material is 15 yuan (below the reuse threshold of 20 yuan), the material's status is updated to "Scrap Recommended."

[0047] Step 8: Feedback the results of the processing method to the system and adjust the inventory records of the materials to reflect the latest status changes; specifically including: Obtain the material's identification code ID, disposal method (such as "reuse recommended" or "scrap recommended"), and current inventory quantity Q; the identification code ID ensures the uniqueness of each material, while the disposal method and current inventory quantity are used to determine the specific operation of inventory adjustment.

[0048] The adjustment factor (AC) is determined based on the disposal method and is used to adjust the material's inventory quantity. If a material is marked "Recommended for Reuse," the adjustment factor is 0.9, indicating that it still has a high reuse value, and the inventory quantity is reduced but not completely eliminated. If a material is marked "Scrap Recommended," the adjustment factor is 0, indicating that the material no longer has any use value, and the inventory quantity is cleared.

[0049] For example, if the disposal method for a building material is "recommended for reuse," the adjustment coefficient AC is 0.9; if the disposal method is "scrapping recommended," the adjustment coefficient AC is 0. By determining the adjustment coefficient, the system can dynamically adjust inventory quantities based on the material's disposal method, ensuring accurate and effective inventory management.

[0050] The material's inventory quantity is updated based on the adjustment factor. The formula is New Inventory Quantity Q = Q * AC, which means the inventory quantity is updated by multiplying the current inventory quantity by the adjustment factor. This helps accurately adjust inventory based on the material's disposal method. For example, if the current inventory quantity Q of a building material is 100 units and the disposal method is "Recommend Reuse," the adjustment factor AC = 0.9, and the new inventory quantity Q = 100 * 0.9 = 90 units. If the disposal method is "Scrap Recommended," the adjustment factor AC = 0, and the new inventory quantity Q = 100 * 0 = 0 units.

[0051] The results of the treatment method are associated with the material's ID and fed back to the database to update the material's status information (such as the treatment method and the new inventory quantity), ensuring that the data in the system is always up-to-date and accurate. This provides reliable data support for subsequent resource management and decision-making.

[0052] Calculate the material's new inventory value (NV) = BV * New Q and record it in the database. The formula NV = BV * New Q calculates the material's new inventory value by multiplying the material's base value by the new inventory quantity. This helps assess the material's remaining economic value throughout its lifecycle.

[0053] For example, if the base value (BV) of a building material is 100 yuan and the new inventory quantity (Q) is 90 units, then its new inventory value (NV) is 100*90 = 9,000 yuan. If the new inventory quantity (Q) is 0 units, then the new inventory value (NV) is 100*0 = 0 yuan. By calculating the new inventory value, the system can determine the actual economic value of the material at the end of its life cycle, providing a basis for subsequent resource optimization and financial decision-making.

[0054] On the other hand, the present invention proposes a smart material management system, such as Figure 2 As shown, including: A material information acquisition module is used to register basic information and initial status of the material, and based on the basic information, calculate and record the maximum number of recycling times of the material; a material information updating module, configured to assign an identification code to a material according to the maximum number of cycles of use, and store the identification code in a database; and whenever the material is used, to update the number of uses in the database and mark the current status of the material; a material evaluation module, configured to check whether a maximum number of recycling times has been reached based on the current state, and if not, continue monitoring until the maximum number of recycling times has been reached; and once the maximum number of recycling times has been reached, evaluate the residual value of the material and record the evaluation result; The material adjustment module is used to determine the reuse or scrapping treatment of the material based on the evaluation results, feed the results of the treatment method back to the system, and adjust the inventory records of the material to reflect the latest status changes.

[0055] In addition, the above-mentioned material information acquisition module, material information update module, material evaluation module, and material adjustment module are also used to implement other steps of the above-mentioned intelligent material management method when executed, which are not described one by one here.

[0056] In summary, this invention achieves precise tracking of material usage by recording the basic information and initial status of building materials in detail, calculating their maximum number of recycling cycles, and assigning a unique identification code to each material. After each use, the database updates the number of uses and current status. Monitoring continues until the maximum number of recycling cycles is reached, at which point the remaining value is assessed and recorded. Based on this assessment, the system determines whether the material should be reused or scrapped, and the resulting disposal is fed back to the system. Inventory records are also adjusted to reflect the latest status changes.

[0057] This series of steps significantly improves the optimal allocation and recycling efficiency of resources, reduces construction costs and resource waste, and realizes efficient management and tracking of construction materials from registration to final processing.
