[0014] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1 As shown, the digital intelligence-driven material management system provided in this embodiment includes: an enterprise material management platform, a mobile terminal 5, an external terminal 6 and an internal terminal 4.

[0016] The enterprise material management platform is integrated in the cloud server; the cloud server includes: a data server 1, an application server 2 and a data backup server 3. The data server 1 is used to store material-related data, and a backup data server is set to ensure data security; the application server 2 is used to carry the enterprise material management platform and read the material-related data in the data server 1; the data backup server 3 is used to back up the material-related data.

[0017] The mobile terminal 5 is used to scan the incoming work tools, materials, and equipment, where the work tools and materials use QR code technology, and the equipment uses RFID technology. The mobile terminal reads the material QR code information, RFID electronic tag information, and storage location QR code information, and transmits them to the enterprise material management platform using wireless signals. The enterprise material management platform automatically builds a material virtual warehouse based on the scanned information and generates virtual material information, realizing the management of incoming and outgoing warehouses and the dynamic tracking of material locations. In addition, RFID technology is used to identify on-site workers, and the mobile terminal automatically detects the working surface location of the workers to realize the dynamic tracking of the personnel location.

[0018] The external terminal 6 is used to access the enterprise material management platform (the material administrator account can log in), manage the materials, including form creation, data filling, statistical analysis, etc., and print material QR code labels.

[0019] The internal terminal 4 is used for the management of the enterprise material management platform. Only the material administrator can log in to maintain the background data of the enterprise material management platform. The enterprise material management platform can be run by supporting a WebGL browser.

[0020] The internal terminal 4 and the external terminal 6 can be mobile phones, based on which the enterprise material management platform can be accessed, thereby improving the flexibility and convenience of material management.

[0021] Furthermore, a firewall 7 is provided between the cloud server and the mobile terminal 5 and the external terminal 6 to ensure the security and reliability of the material information.

[0022] Furthermore, the enterprise material management platform includes: project management module, personnel management module, material management module, supplier management module, capital management module, cost management module, risk management module, quality management module, material coding module, statistical analysis module and other functional modules. Comprehensive material management is achieved from the whole process of issuing material demand plan, comprehensive material dispatch, inbound / outbound management, etc.

[0023] (1) Project management module.

[0024] The project management module establishes company-level, project-level, and warehouse-level material management trees based on the enterprise material management platform. It inputs information such as project name, project number, warehouse name, warehouse number, etc. It has functions such as adding, deleting, and modifying to achieve coordinated management of materials for all projects under construction. Figure 2 At the same time, a project structure tree is created based on the enterprise material management platform, and the BIM model is uploaded according to this structure tree, which is convenient for reference in the material requirement plan based on the construction progress.

[0025] (2) Personnel management module.

[0026] The personnel management module registers project participants based on the enterprise material management platform, identifies the personnel's organization, position, type of work, number, on-the-job status, work location, and work surface, and conducts comprehensive scheduling of personnel.

[0027] The personnel scheduling method is: based on the BIM model progress and personnel demand indicators, dynamically calculate the number of personnel requirements, combine the work surface progress plan, form a "work surface-number of personnel" comprehensive scheduling form, dynamically adjust personnel arrangements, and maximize labor utilization.

[0028] (3)Material management module.

[0029] The material management module is used to manage equipment, materials and tools, as well as to implement standardized material management processes, calculate and provide material requirement plans.

[0030] The material management module is the core module of the enterprise material management platform, which includes the equipment management sub-module, material management sub-module, tool management sub-module, material standardization management process sub-module and material requirement planning sub-module.

[0031] 3.1) Equipment management submodule.

[0032] The equipment management submodule registers and identifies the name, specification, model, etc. of the equipment based on the enterprise material management platform, and identifies the status based on the mobile terminal scanning of the equipment RFID electronic information tag. The identification information includes "in warehouse", "out of warehouse", and "installation completed", dynamically monitoring the location and installation status of the equipment.

[0033] 3.2) Material management submodule.

[0034] The material management submodule registers and identifies the name, specification, model, etc. of the materials based on the enterprise material management platform, uses wireless scanning technology to dynamically monitor their location information, and conducts comprehensive scheduling of materials.

[0035] like Figure 3 As shown in the figure, the material scheduling algorithm is as follows: based on the BIM model, the enterprise material management platform integrates the engineering quantity statistics function, combines the working face, automatically generates the working face material list, takes the same specification full-length pipeline as a statistical unit, and all types of full-length pipelines form a queue to perform pipeline virtual piping. For a single pipeline, first determine whether the length of the single pipeline is greater than the maximum modulus. If it is greater, the maximum modulus pipeline is used for piping. When the maximum modulus pipeline is difficult to meet the requirements, determine whether other modulus pipelines meet the requirements from large to small. When the minimum modulus pipeline cannot meet the requirements, only the missing pipeline length is statistically analyzed to establish a surplus material database. A comprehensive statistical analysis is performed on the surplus material database, and the surplus material is statistically analyzed with the modulus as the object. If the relevant modulus can realize the surplus material combination, the relevant modulus is used for batching. If not, the optimal modulus is selected for batching based on the material utilization rate. Try to use one pipe section to achieve the expected division, reduce the generation of surplus material, and improve the material utilization rate.

[0036] The material utilization rate is calculated as follows:

[0037]

[0038] In the formula, η is the material utilization rate; r is the length of the surplus material; i represents the number of surplus materials; m is the sum of the number of surplus materials to be combined; L is the length of the material; j represents the number of pipes with different modules.

[0039] The enterprise material management platform combines material utilization indicators and automatically performs multi-scheme virtual piping calculation and analysis based on the modular database to maximize material utilization.

[0040] 3.3) Tool management submodule.

[0041] The tool management submodule registers and identifies the name, specification, model, etc. of tools based on the enterprise material management platform, uses wireless scanning technology to dynamically monitor their location information, and conducts comprehensive scheduling of tools.

[0042] The tool scheduling method is to combine the construction progress of the BIM model and the tool demand indicators. The enterprise material management platform automatically calculates the tool demand list, optimizes the mobilization and dynamic management of tools between different projects and different work surfaces; at the same time, it monitors the operating status of tools based on chips, analyzes the utilization rate of tools, provides data support for the optimization of tool demand indicators, and continuously corrects the scheduling plan.

[0043] 3.4) Material standardization management process sub-module.

[0044] The material standardization management process submodule is used to execute the material standardization management process, which is as follows:

[0045] 3.4.1) Identify materials.

[0046] The coding function module of the enterprise material management platform is called through the external terminal 6 to automatically encode the tools, materials and equipment. The name, specification, model, unit price, status and other related information of the tools, materials and equipment are input through the external terminal 6. After the input is completed, the external terminal 6 sends a coding request instruction to the enterprise material management platform. The enterprise material management platform automatically encodes the materials, tools and equipment based on the automatic coding algorithm, and sends instructions to the external terminal. The external terminal 6 is connected in series with the printer to print the coding information of the tools and materials in the form of a QR code and post it on the tools and materials. In addition, for the equipment, its coding information is stored in an RFID tag and fixed on the surface of the equipment to achieve the uniqueness of the material information pointing.

[0047] 3.4.2) In / out warehouse management.

[0048] Warehouse management: When entering the warehouse, the enterprise material management platform is accessed based on the mobile terminal 5 to formulate a material entry form. Subsequently, the mobile terminal 5 is used to scan the QR code or RFDI electronic tag of the material and the QR code of the warehouse to be entered. At this time, the material information and entry information are transmitted to the enterprise material management platform, forming a virtual warehouse on the platform side to achieve dynamic visual display. At the same time, the enterprise material management platform provides a manual entry method. Based on the material demand plan, the actual material procurement situation is modified to formulate a material entry statistical table and a material acceptance form. The platform automatically generates a unique QR code for the material acceptance form.

[0049] Return management: Standard modular materials are returned using the warehouse entry management method; for leftover materials, they need to be re-labeled using the external terminal 6, and the specifications, dimensions and other parameters of the leftover materials are registered, and they are marked as leftover materials, and they are re-entered into the warehouse according to the warehouse entry management method; for tools and equipment, they are re-entered into the warehouse according to the warehouse entry management method.

[0050] 3.4.3) Outbound delivery management.

[0051] Issue order: After selecting the receiving unit, project, and issuing warehouse, enter the material number to add the material, enter the quantity, and generate the material pick list according to the generated order.

[0052] Outbound management: Use a handheld mobile terminal 5 to scan the QR code or RFID electronic tag of the material and mark it as outbound status. The mobile terminal 5 automatically transmits the information to the enterprise material management platform, and the enterprise material management platform automatically adjusts the status of the material to outbound.

[0053] 3.4.4) Installation management.

[0054] After the materials are moved to the designated area, the mobile terminal 5 is used to scan the QR code or RFID electronic tag on the materials, and the material status is adjusted to entered; after the materials are installed, the mobile terminal 5 is continued to be used to scan the QR code or RFID electronic tag on the materials, and the material status is adjusted to installed. The mobile terminal 5 automatically transmits the "installed" status information of the materials to the enterprise material management platform, matches the material information with the BIM model, and dynamically adjusts the progress information of the BIM model. The enterprise material management platform dynamically forms a list of labor, tools and equipment requirements based on relevant indicators, and uniformly dispatches and manages personnel, tools and equipment based on this. Based on the unfinished project volume, the manpower, material and machine plan is reversed to achieve dynamic tracking of manpower, material and machine.

[0055] 3.5) Material requirement planning submodule.

[0056] The material requirement plan submodule is used to calculate and provide material requirement plans. The specific methods for calculating and providing material requirement plans are as follows: establish a mainline indicator database based on historical data of similar projects and similar work surfaces; establish an auxiliary indicator database based on actual data of similar work surfaces in the same project; based on the mainline indicator database and the auxiliary indicator database, use data analysis technology to dynamically calculate indicators; the indicators include: tool indicators, personnel indicators and material indicators; determine the material requirement quantity based on the indicators; determine the allocation list; the allocation list includes material and component allocation lists and tool and personnel allocation lists; determine the material requirement plan based on the allocation list and the material requirement quantity.

[0057] 3.5.1) If Figure 4As shown in the figure, based on the historical data of enterprise projects, a database of main indicators for personnel, tools, and materials is built; in view of the fact that the indicators for the required materials of project construction are related to multiple factors such as project type, regional location, and working environment, it is necessary to feature the existing data, and the feature identification includes different project types, different geographical regions, different types of working surfaces, floor clear height, pipeline density, and other characteristics, forming an enterprise-level database of personnel, materials, and machines. Based on the main indicator database, a material demand indicator system is formulated, including unit area indicators, unit volume indicators, etc.; at the same time, combined with the actual data of the same type of working surface of the same project, the data on the use of personnel, tools, and materials is dynamically collected and transmitted to the enterprise material management platform in real time, an auxiliary indicator database is established, and data is collected to continuously iterate and update the indicators; based on the main indicator database and the auxiliary indicator database, the material data used in the project with similar feature identification to the working surface under construction is extracted, and the required indicators of tools, personnel, and materials are dynamically calculated using data analysis technology, laying the foundation for determining the quantity of material demand.

[0058] 3.5.2) The enterprise material management platform is interconnected with the BIM model through the interface between the BIM model and the data, automatically extracts the functional characteristics of the BIM model working surface (functional characteristics, floor clear height, pipeline density), conducts a comprehensive analysis of the functional characteristics, and automatically outputs the optimal indicators of material demand for similar working surfaces. For example, for building mechanical and electrical systems, first, the enterprise material management platform exports the mechanical and electrical system engineering quantity of the working surface based on BIM, including the types and quantities of components, specifications and lengths of pipelines, etc.; secondly, the platform uses material scheduling algorithms to perform virtual piping, and determines the module and quantity of pipelines based on the principle of optimal material utilization to form a material allocation list; at the same time, for the allocation of tools and personnel, the platform has an indicator optimization function, and proposes a dual indicator system of similar working surface indicators for the same project and similar working surface indicators for similar projects. The system automatically or manually defines their respective weights. Based on engineering experience, the proportion of similar working surface indicators for similar projects should be 30%, and the weight of similar working surface indicators for the same project should be 70%, thereby obtaining weighted indicators for material requirements, using the optimized indicators and combining them with the working area or volume to analyze and calculate the types and quantities of tools and personnel on the working surface to form a tool and personnel allocation list; based on the above process, data support is ultimately provided for material collection. The specific process is as follows: Figure 5 shown.

[0059] 3.5.3) The material requirement plan is presented in the form of a statistical table, including material number, material name, specification model, material, unit, planned quantity, tender unit price, tender quantity, tender amount, etc. The material requirement plan form includes submission time, document number, preparation date, preparer, profession, approval status, approval opinion, approval date, etc.

[0060] (4)Supplier management module.

[0061] The supplier management module establishes a supplier database based on the enterprise material management platform to clarify the supplier's supply type, supply quantity, unit price and other information.

[0062] (5) Fund management module.

[0063] (6)Cost management module.

[0064] (7)Risk management module.

[0065] The capital / cost / risk management module uses an external terminal 6 to operate the enterprise material management platform, input material prices, and form a price database; based on the material quantity and price database, it performs cost calculations, forms cost statistics reports and related indicators, analyzes related indicators in a timely manner, promptly finds process management loopholes, and improves the transparency of project cost management, capital control, and risk prevention.

[0066] (8)Quality management module.

[0067] The quality management module includes three dimensions: summary by construction team, summary by material, and summary by supplier. It enables analysis of material supply situations from different dimensions and realizes material quality traceability and comprehensive management.

[0068] (9)Material coding module.

[0069] The coding management module is used to automatically code tools, materials, and equipment. The specific coding methods are as follows:

[0070] 9.1) Establish a unified warehouse number at the enterprise level, number different warehouses, and formulate warehouse labels, including project name, warehouse type, and warehouse number.
