[0032] This application takes a highway section improvement and reconstruction project as an example to build a smart construction site project management platform. Figure 1 As shown in the figure, the application data of beam yard, mixing station, vehicle positioning, production progress management, video monitoring, tunnel safety monitoring, etc. are integrated and displayed on the same platform.

[0033] This application provides a set of smart construction site project management platforms that cover the information, knowledge, tools, platforms, and methods required for digital transformation. As the core function of digital projects, IOT and BIM technologies are used to integrate on-site hardware equipment into a unified platform, and the generated data is summarized and modeled in real time to form a data center, so that the project management level can fully grasp the production process, and use artificial intelligence technology to intelligently identify project risks and issue warnings, so as to build a platform for the project management level to summarize data in real time, fully grasp the production process, and effectively reduce project risks.

[0034] First, the construction process of the smart construction site project management platform is introduced, including infrastructure project decision-making design, smart Internet of Things design, system security design, database design, data generation type design, and data docking method and frequency design.

[0043] System users include tenant administrators and common users.

[0044] Tenant administrators can enter the user center to view basic information, change login passwords, and change security phone numbers.

The bound security mobile phone number can only be used to retrieve the password, not to log in; the bound mobile phone account can be directly used for login, password retrieval, etc.

[0046] like Figure 2 As shown, the execution entities of the smart construction site project management platform provided by this application include browsers, applications, personal computers and third parties, and the development languages ​​and frameworks used include load balancing, reverse proxy, site, service gateway and application interface gateway. The service part includes service governance, basic business services and public services. Among them, service governance includes discovery (Eureka) service, configuration service, fuse monitoring and link tracking; basic business services include login service, user service, tenant service, organization service, role service, permission service, tenant product authorization service, authorization file generation service, project extension information service, product service, sales service and project configuration service; public services include push (PUSH) service, sequence (Sequence) service, SMS gateway service, SMS address service, data synchronization service and report printing service. The designed underlying database includes relational database management system (MySQL), remote dictionary service (Redis), object storage service (Object Storage Service, OSS), distributed database service (Table Store, OTS) and message queue (Message queue, MQ).

[0047] This application adopts a unified cloud platform to make the data of the internal system highly consistent, running through the entire software and hardware data system, so that scalability and consistency can be guaranteed. A high-performance Internet of Things platform is used to make hardware access safe and stable. The overall architecture is centered on microservices to achieve unified platform microservice governance. This architectural approach achieves large-scale support, reduces duplicate development, and facilitates expansion and maintenance. The platform splits the system business into components and services, splitting them into independent microservices, which are uniformly managed by the service governance center. Each microservice is an independent container, and the communication between microservices is completed through remote procedure calls (RPC), representational state transfer (REST) ​​or message queues to achieve maximum decoupling and reuse. The deployment method uses K8S containerized deployment to reduce the service's dependency on infrastructure.

[0048] This architecture has the following advantages:

[0049] ① Complexity is controllable. While decomposing the application, the endless accumulation of complexity is avoided. Each microservice focuses on a single function and clearly expresses the service boundary through a well-defined interface. Due to its small size and low complexity, each microservice can be fully controlled by a small development team, making it easy to maintain high maintainability and development efficiency.

[0050] ② Independent deployment. Since microservices have independent running processes, each microservice can also be deployed independently. When a microservice changes, there is no need to compile and deploy the entire application. An application composed of microservices is equivalent to having a series of parallel release processes, making release more efficient, while reducing the risks to the production environment, and ultimately shortening the application delivery cycle.

[0051] ③ Flexible technology selection. Under the microservice architecture, technology selection is decentralized. Each team can freely choose the most suitable technology stack based on its own service needs and the current status of industry development. Since each microservice is relatively simple, the risk of upgrading the technology stack is low, and it is even feasible to completely reconstruct a microservice.

[0052] ④ High fault tolerance. When a component fails, in the traditional architecture of a single process, the fault is likely to spread within the process, causing the application to be globally unavailable. In the microservice architecture, the fault will be isolated in a single service. Other services can achieve application-level fault tolerance through mechanisms such as retries and smooth degradation.

[0053] ⑤ Scalability. Monolithic applications can also be expanded horizontally, that is, the entire application is completely copied to different nodes. When different components of the application have different expansion requirements, the microservice architecture will show its flexibility, because each service can be expanded independently according to actual needs.

[0054] 3) System security design

[0055] The data security of users is the lifeline of users and is also one of the most important concrete manifestations of the overall security capabilities of the smart construction site project management platform. The requirements for data security can be summarized by the three basic elements of information security: confidentiality, integrity, and availability. Confidentiality specifically refers to the fact that protected data can only be accessed by legitimate (or expected) users. Its main implementation methods include data access control, data leakage prevention, data encryption, and key management. Integrity is to ensure that only legitimate (or expected) users can modify data, which is mainly achieved through access control. At the same time, the integrity of user data can be guaranteed by verification algorithms during data transmission and storage. The availability of data is mainly reflected in the overall security capabilities, disaster recovery capabilities, and reliability of the cloud environment, as well as the normal operation of various related systems on the cloud (storage systems, network paths, identity authentication mechanisms, and permission verification mechanisms, etc.). This application stores all data on the Huawei cloud platform to improve data security.

[0056] 4) Database design

[0057] The database design should follow the following principles:

[0058] ① Standardized naming. All database names, table names, and domain names must follow unified naming rules and provide necessary explanations to facilitate design, maintenance, and query.

[0059] ② Control the reference of fields. When designing, you can choose appropriate database design management tools to facilitate the distributed design of developers and the centralized review and management of data teams. Use a unified naming rule. If the designed field already exists, it can be directly referenced; otherwise, it should be redesigned.

[0060] ③ Library table duplication control. During the design process, if it is found that most of the fields already exist, the developer should doubt whether the library table designed already exists. By querying the library table where the field is located and the corresponding designer, it can be confirmed whether the library table is indeed duplicated.

[0061] ④ Concurrency control. Concurrency control should be implemented in the design, that is, for the same database table, only one person has control at the same time, and others can only query.

[0062] ⑤Header file processing. After each data modification, the corresponding header file needs to be modified and the relevant developers need to be notified so that the corresponding program modifications can be made.

[0063] 5) Design of generated data types

[0064] The types of data generated include real-time equipment data, equipment alarm data, equipment image data, equipment business data, business data of each business module, etc.

[0065] 6) Data connection method and frequency design

[0066] This application supports data push of protocols such as Hypertext Transfer Protocol (HTTP), Transmission Control Protocol (TCP), Message Queuing Telemetry Transport (MQTT), etc.; push according to standard protocols; push according to the docking party format; support historical data query. Dynamic docking frequency is adopted, and the frequency can be dynamically set according to the docking party interface definition. There is no frequency limit by default.

[0067] In an exemplary embodiment, Figure 3 As shown, a smart construction site project management platform is provided, including: a project command and dispatch center 301, a progress visualization management system 302, a material management system 303, a tunnel management system 304, a mixing station management system 305 and a beam yard management system 306.

[0068] In this application, the project command and dispatch center 301, the progress visualization management system 302, the material management system 303, the tunnel management system 304, the mixing station management system 305 and the beam yard management system 306 are used for different business departments, and their basic data and results are shared, and interconnection is achieved through the data middle platform.

[0069] In a specific example, the progress visualization management system 302, the material management system 303, the tunnel management system 304, the mixing station management system 305 and the beam yard management system 306 are all functional modules in the project command and dispatch center 301. The project command and dispatch center 301 is deployed in a computer device.

[0070] The functions of each system are introduced below.

[0071] (1) Project Command and Dispatch Center 301

[0072] The project command and dispatch center 301 is connected to the business management system of the construction site to obtain the operating data of the hardware equipment on the construction site from the business management system, and generate a three-dimensional visual project layout diagram based on the operating data of the hardware equipment on the construction site to intuitively display the basic situation of the project.

[0073] The hardware equipment on the construction site includes sensors, access control, cameras, high-definition scanners, video hosts, mobile terminals, printers, industrial control desks, weighbridges and infrared beamforming devices. The hardware equipment on the construction site is connected to the mobile application and data analysis platform through the Internet.

[0074] In a specific example, the project command and dispatch center 301 uses building information modeling and geographic information system to generate a three-dimensional visualized project layout diagram. That is, the project command and dispatch center 301 forms a three-dimensional visualized project layout diagram by superimposing GIS maps through BIM modeling to replace the traditional project floor plan and project overview board, thereby intuitively displaying the basic situation of the project through a real-time online digital project panorama, allowing the management to quickly and intuitively understand the project overview and operation status.

[0075] In another exemplary embodiment, the project command and dispatch center 301 is also used to determine the production plans for multiple time periods within the project construction cycle based on a pre-built project plan, obtain on-site production data at the end of each time period, and determine whether the production plan is met based on the on-site production data and the production plan for the corresponding time period. If not, adjust the production plan for the next time period.

[0076] In another exemplary embodiment, the project command and dispatch center 301 is also used to visualize the space, environment, components, personnel, machines and materials of the construction site through an electronic sand table. The on-site image progress and construction deviation can also be visualized through the electronic sand table. At the same time, roaming videos can be quickly produced based on the electronic sand table, which has a very good application effect in image display. The maps in the electronic sand table are divided into oblique photography and purchased Baidu maps.

[0077] The project command and dispatch center 301 is connected to the business management system of the construction site through the Internet of Things equipment, collects data such as labor, materials, progress, videos, etc. on the construction site, and assists on-site management through pre-designed internal management logic. For example, when managing the production progress, first upload the overall project plan, and the project command and dispatch center 301 automatically generates a weekly plan (including the number of people required, the number of machines required, the amount of materials required, etc.) according to the overall project plan, and compares the weekly plan with the data collected on site to determine whether it meets the production plan.

[0078] This application integrates, analyzes, processes and stores the data of smart construction site related applications by establishing a project command and dispatch center 301. Project managers can quickly understand the core data of project management through the data analysis platform of the project command and dispatch center 301, including safety and quality warning conditions, distribution of man-machine materials, real-time progress status, on-site video, etc., to assist in scientific management of the project and improve the level of project management. The project command and dispatch center 301 can also be used to achieve unified management of project camps, beam yards, steel bar processing plants and other sites, and realize dynamic management of major production factors such as labor personnel, machinery and equipment, materials, and environment. Through labor management, the labor management needs of infrastructure projects such as roads, railways, roads and bridges, tunnels, and closed and non-closed scenarios are met, and information management is used to help enterprises avoid labor risks, improve project progress, and reduce labor costs.

[0079] This application has created a project command and dispatch center 301 that can be observed, commanded, and moved. The command center uses a digital construction platform for project management and adopts modern scientific and technological equipment to combine the BIM model with on-site construction briefing, production, safety, and quality. At the same time, the on-site equipment is intelligently monitored through the smart construction site system to create an integrated platform for digital command. Specifically, the digital exhibition hall was built from three aspects: digital operation, digital command, and intelligent experience. Among them, the BIM model is combined with on-site construction briefing, production, safety, and quality to lead a new generation of construction mode with visual management and digital operation; digital command provides data visualization dashboards, presents the status and key data of various elements of the construction site as a whole, remotely grasps risks and hidden dangers, and conducts remote command and dispatch; uses augmented reality / virtual reality / hybrid display and other forms of intelligent experience, so that visitors can have an immersive experience and achieve efficient technical briefing and production management.

[0080] (2) Progress visualization management system 302

[0081] The progress visualization management system 302 is used to obtain project construction progress information and generate a three-dimensional visualization engineering model based on the project construction progress information to display and manage the project construction progress.

[0082] Specifically, a project includes multiple unit projects. Visual progress is the core indicator of infrastructure project control and management progress, and the visual progress wall chart that has been used for decades is also the most popular and commonly used tool for visual progress. Visual progress wall charts usually draw and display the components of unit projects such as bridges, tunnels, and culverts in two dimensions, and then mark the progress completion status of each component by coloring according to the actual progress. The visual progress wall chart can be used to view and understand the overall progress of the entire project at a glance, and can also be used to introduce or report on the progress completion of the project. Visual progress wall charts Figure 1It is usually hung on the walls of the project manager's office, other project leaders' offices, project meeting rooms and other indoor places where needed.

[0083] The three-dimensional visualization engineering model constructed in this application displays the visual progress through the color difference of the model, and can also compare the design quantity and the actual quantity, that is, the loss quantity.

[0084] In another exemplary embodiment, the progress visualization management system 302 is also used to use a built-in parametric modeling tool to define the type of each unit project, and construct a three-dimensional visualization engineering model of each unit project based on the comprehensive parameters of each unit project. For any unit project, the project construction progress information input by the user on the client is obtained, and the project construction progress information is embedded in the three-dimensional visualization engineering model of the unit project to display and manage the construction progress of the unit project.

[0085] The progress visualization management system 302 has a built-in standard component library that meets the common types of infrastructure projects. The standard component library is mainly used to meet the needs of visual progress display and expression. For example, the bridge component library contains common bridge foundation types, piers and beam models. The standard component library supports the addition of component types according to the actual needs of the project to form an enterprise component asset library. At the same time, the progress visualization management system 302 also supports the import of existing BIM models of the project.

[0086] This application mainly uses the built-in parametric modeling tool. By defining the unit project type and then entering the comprehensive parameters of the unit project, a three-dimensional visual engineering model that meets the requirements of project image progress display and management can be quickly built. For example, the parametric modeling of the bridge image progress model only needs to define the type of bridge (simply supported beam, continuous beam, continuous T-structure or other types), and then enter the starting and ending mileage of the bridge location, the number of spans, the length of the span, the number of beams arranged per span and the cross-sectional form of the beam body, the type of bridge foundation, the arrangement of pile foundations, the type of piers, and other core parameters, and the overall bridge model can be produced with one click.

[0087] Users can report progress completion status in a timely manner through mobile applications or mini-programs. This application can further preview the visual progress of all unit projects or view detailed progress information through the "Visual Progress" menu on page 301 of the project command and dispatch center. On the "Visual Progress" homepage, you can identify the progress status of each unit project, and use a flashing red light to prompt the unit project with lagging progress. You can also switch to the visual progress chart of a specific unit project to view detailed component progress information.

[0088] (3) Material Management System 303

[0089] The material management system 303 is used to adopt the Internet of Things technology to automatically collect material information through hardware equipment on the construction site, so as to remotely monitor and manage the materials on the construction site.

[0090] This application realizes all-round lean management of materials entering and leaving the site through the material management system 303, and adopts the Internet of Things technology to intelligently and automatically collect material information through peripheral hardware equipment such as weighbridges. Data integration and cloud computing technologies are used to timely grasp first-hand data, effectively accumulate, preserve and increase the value of material data assets. The Internet and big data technologies are used for multi-project data monitoring and full-dimensional intelligent analysis. Mobile Internet technology is used to control the site and identify risks anytime and anywhere, and realize zero-distance intensive management and control and visual decision-making.

[0091] In a specific example, the material management system 303 can be connected to the scale at the construction site, and the materials can be automatically weighed through the scale, and the material information can be sent to the material management system 303, ensuring that no one can modify the weighing data, ensuring the authenticity and accuracy from the source of the data, avoiding the existence of human factors such as manual errors, and ensuring that the materials are actually weighed and put into storage. Through the automatic association between the material management system 303 and the scale, it can be traced when problems arise in the material management process. In addition, the material management system 303 can also analyze and organize the material information and export reports.

[0092] The material management system 303 can also analyze the details and summary of material delivery and receipt, and update them dynamically in real time to objectively, truly and accurately reflect the situation of material delivery and receipt. It can combine and analyze multiple perspectives such as time, material supplier, source, deviation, etc. to support actual procurement, actual arrival and actual material delivery analysis, and provide accurate data support for procurement plans, funding plans, material arrangements, project progress, etc.

[0093] (4) Tunnel Management System 304

[0094] The tunnel management system 304 is used to obtain tunnel information involved in the project in real time, and to remotely monitor and manage the construction process in the tunnel based on the tunnel information.

[0095] In a specific example, the tunnel information includes: tunnel personnel labor information, tunnel personnel location information, gas information, safe step distance, monitoring video, personnel entering and exiting the tunnel, and vehicles entering and exiting the tunnel.

[0096] Gas information includes gas detection and non-gas detection. The safety step distance uses laser radar to measure distance accurately.

[0097] The process by which the tunnel management system 304 remotely monitors and manages the construction process in the tunnel based on the tunnel information specifically includes: performing safety monitoring of personnel in the tunnel based on the tunnel personnel labor information, the tunnel personnel positioning information, the safe step distance, the monitoring video, personnel entering and exiting the tunnel, and vehicles entering and exiting the tunnel; determining whether the gas in the tunnel exceeds the safety threshold based on the gas information, and issuing an alarm when the gas in the tunnel exceeds the safety threshold.

[0098] The tunnel management system 304 of the present application displays data such as tunnel personnel labor information, tunnel personnel positioning information, gas information, safe step distance, monitoring video, etc. through a billboard, and can also monitor the personnel and vehicles entering and leaving the tunnel in real time. It further counts attendance and various labor warnings in different dimensions, and alarms are issued in combination with real-time personnel positioning. When the gas in the tunnel exceeds the standard, an alarm is issued to ensure the safety of on-site workers.

In this way, the drawings can be stored in an orderly manner and managed as a whole, which is convenient for project personnel to find and view; the drawing update version, the issuance and receipt management, ensure the timeliness and accuracy of the drawing viewing by all parties; drawing comparison and drawing package version comparison make it easier for project personnel to understand the updated content of each version of the drawings.

[0115] ②The business scenario of change management is: due to inadequate change management in a certain project, the subcontractor implemented the old changes, resulting in a demolition and modification cost of 230,000 and a delay of 10 days in the construction period; due to the loss of visa record information in a certain project, the settlement loss was 134,000; due to the inadequate implementation of the subcontractor in a certain project, the subcontractor claimed improper supervision, and the general contractor ultimately assumed part of the responsibility and construction period loss. The solution is to view the change drawings in a linked manner, and provide SMS early warning reminders to reduce omissions, change review and other records, and export them online with one click. View relevant change and review records through drawings to avoid missing changes and rework; remind drawing review and change content according to the progress of the project to avoid unclear responsibilities; electronically archive change and visa documents to support settlement and avoid settlement losses.

The solution is to assign responsibility for the solution plan to individuals, provide early warning reminders, and record the entire process of solution disclosure and review. Then form a solution preparation plan, assign responsibilities to individuals, and issue early warnings according to the planned time to prevent delays in preparation; manage the entire process from solution approval to demonstration disclosure and review, forming a closed management loop to reduce the risk of inadequate solution implementation and incomplete information.

[0117] ④ The business scenarios of briefing management are: sharing of briefing materials is not easy to use, shared materials on social software are easy to expire, have size restrictions, and viewing without records can easily lead to disputes; the text briefing requirements for key parts and difficult nodes are difficult to understand, which can easily lead to on-site problems; the briefing process is not closed-loop, and the responsibility is not clear after problems occur. The solution is WeChat applet + QR code to search for materials, 3D node + process animation briefing, and briefing notification sharing, assessment and signing full process records.
