Technical Field

[0001] The present invention relates to the technical field of construction drawing review, and in particular to a construction drawing digital review system and method based on information technology. Background Art

[0002] Construction drawing review is the first supervision checkpoint for engineering construction quality, which can correct the quality and safety hazards and violations of mandatory standards in project design. The traditional paper drawing interactive mode of drawing review objectively wastes resources to a certain extent, and circulation, archiving and consultation are not very convenient. Moreover, due to the influence of human factors, problems such as missed inspections and misjudgments are prone to occur, making it difficult to ensure the accuracy and consistency of construction drawing review. The review of construction drawings for construction projects involves multiple units such as construction, fire protection, civil defense, and technical defense. The construction unit must submit them for review separately, which increases the burden and cost. Different departments are in front of each other, which can easily lead to jams and delays in drawing review, affecting the progress of project construction. Realizing the association of construction drawing review links is the only way to improve public service capabilities.

[0003] The basis of joint review is digital review, so the first thing to be realized is the digital review of construction drawings. Digital review is a digital review process that integrates drawing review and supervision, and replaces paper drawing files with computer-related technical means to carry out network transmission, storage, review and management of drawing materials around the review business process. The object of digital review is "digital design files", and the parties involved are construction units, survey and design units, review agencies, and management departments. The matters handled include transmission, storage, review, management, and sharing of drawings. With the development of information technology, digital review of construction drawings has gradually become a trend. By using computer technology and automation tools, the efficiency and accuracy of review can be improved, and many problems of traditional review methods can be solved.

[0004] Xinchuang technology, namely information technology application innovation technology, aims to achieve independent control in the field of information technology and ensure information security through independent research and development of core technology products in the IT industry chain such as hardware and cloud infrastructure, basic software, application software, and network security. It is not only the foundation of data security and network security, but also an important part of new infrastructure. As an emerging technical means, Xinchuang technology has important application value in the digital review of construction drawings. Summary of the invention

[0005] In order to solve the problems of how to realize the digital joint review of construction drawings through the information and innovation technology, thereby improving the efficiency and accuracy of the review, the present invention proposes a digital review system and method for construction drawings based on information and innovation, covering the whole process of project registration, drawing upload, opinion generation, signature management, etc., effectively improving the standardization and normalization of construction drawing review.

When the survey and design unit double-clicks an opinion, the system automatically opens the problematic drawing and locates the expert's annotation location. When the survey and design unit responds to the revision of the drawings, the revised drawings will not cover the previous round of drawings. Instead, the new version of the drawings will be uploaded after the previous round of drawings, and the replacement relationship of the drawings will be presented in a tree structure; In the construction unit module, the construction unit registers the project for review through the project review tool. After the project registration is completed, the survey and design unit shall upload the survey report or design drawings according to the individual project, and then the construction unit shall complete the project information and upload the policy review materials, and confirm the submission for review; if the policy materials provided during the first review are incomplete, it will be regarded as a pre-review project and the drawing review process will continue. At the same time, the review agency will initiate the material correction, and the construction unit or the survey and design unit will submit the missing materials again.

[0010] A further improvement of the present invention is that the review agency module automatically verifies the signature of the uploaded survey report or design drawing when accepting the review uniformly, and automatically detects whether the survey report or design drawing is password-protected, damaged, and contains potentially dangerous script content. The verification is verified by the review service window to verify the integrity and accuracy of the project information, technical review materials, and policy review materials. For projects that include fire protection and civil air defense reviews, fire protection and civil air defense drawings are quickly searched and viewed. If the verification is passed, it is formally accepted for review. If the materials are incomplete, a correction notice is issued to allow the survey and design unit or construction unit to complete the materials and resubmit for review; After receiving the review task, the review agency manager will allocate the review task according to the reviewer's workload prompted by the system. The system will automatically notify the relevant reviewers and specify the professional reviewers and review time limits.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0018] like Figure 1 , Figure 3-Figure 6 As shown, this embodiment provides a digital review system for construction drawings based on information technology innovation, adopts the ASP.NET Core (a free and open source Web framework) cross-platform technology system, has two deployment modes: single mode and cluster mode, and is implemented in combination with a microservice architecture.

[0019] The existing two-dimensional drawing review system is built using Microsoft's .NET Framework technology platform. Since .NET Framework is deeply bound to the Windows platform, it cannot be cross-platform. The operating systems under the domestic information innovation environment are mostly based on the evolution of the Linux kernel, so the existing two-dimensional drawing review system cannot be deployed to the Linux system environment for operation. In order to meet the requirements of domestic information innovation, this embodiment adopts Microsoft's new generation of open source, free, cross-platform, high-performance, mature and stable .NET Core technology system to build a high-performance B / S architecture application that can be deployed and run in Windows and Linux servers at the same time. The system supports two deployment modes: single mode and cluster mode. It can be flexibly switched in different application scenarios to meet the needs of users of different scales and needs, and make full use of the advantages of the two architectures. This flexibility is of great significance to the scalability, maintainability and performance optimization of the system.

[0020] The system service layer adopts a microservice architecture, splitting the traditional one-stop application into individual services according to the business scope. Each microservice provides a complete service for a single business function, which is an independent business processing process with simple code logic and high development efficiency. Each microservice can be horizontally expanded at any time according to the system performance requirements. When a service unit cannot meet the system performance requirements, multiple services can be started at the same time for performance expansion. The system adopts the Spring Cloud distributed microservice framework in its implementation, and uses the complete microservice architecture technology stack provided by SpringCloud to build the system microservice framework.

[0021] The system specifically includes: Client, used to support a variety of domestic browsers such as Loongson Browser, 360 Security Browser, Qi'anxin Trusted Browser, Red Lotus National Confidential Browser, and instant messaging tools such as WeChat, so that users can access and operate the system through various terminal devices; The application layer is used to realize project registration, drawing upload, project review, drawing review, review opinion, opinion approval and issuance, and the whole process management of construction drawing review with a set of drawing signatures through the construction engineering multi-drawing joint review system, and provides docking and mobile office functions with third-party systems such as the provincial construction drawing comprehensive supervision platform, provincial fire protection system, municipal industrial reform system, municipal smart housing and construction system, and municipal credit evaluation system; Common modules are used to provide cross-application sharing functions, including email management, SMS management, WeChat messaging, instant messaging, single sign-on, identity authentication, configuration management, resource management, cache management, template management, report center, PDF / ODF management, signature management, organization management, personnel management, module management, module permissions, function permissions, data permissions, data dictionary, etc. The platform layer is used to provide basic system services, including object storage subsystem, private NuGet server, automated project generator, automated deployment and operation system, security subsystem, log subsystem, task scheduling subsystem, and workflow subsystem. Databases use domestically produced trust-based databases such as OceanBase, GaussDB, TDSQL, and TeleDB to run directly on the operating system and are used for the storage, management, and retrieval of all system data, including the electronic document information base of construction drawings, the structured information base of construction drawings, and related business databases; Operating system, based on domestic operating systems such as Kylin, UOS, Loongnix, OpenEuler, etc., used to manage hardware resources and system processes; Processor, supports a variety of domestic processors such as Kunpeng, Feiteng, Loongson, etc., for all computing tasks of the system and applications.

[0022] The system deployment and construction environment meets the requirements of localization adaptation of Xinchuang, taking into account the requirements of openness, flexibility, security and easy maintenance. The server comprehensively considers factors such as project requirements, technical requirements and ecosystem compatibility, adopts Xinchuang cloud virtual server and selects Kunpeng 920 ARM64 architecture domestic CPU as an alternative option; the operating system is Kirin or Euler domestic operating system, which supports cloud native applications and meets the needs of domestic virtualization and docker containerization. At the same time, the system is the same source as the domestic Kunpeng 920 platform, and can be compatible and adapted; the database is the domestic database DM8 or GaussDB, which supports data backup and recovery, data security and permission control and other functions; PDF drawing review technology is based on the WebPDF Viewer product, which realizes fast display, annotation, measurement, comparison and signing functions through a web browser on desktop and mobile devices, without the need to download any additional plug-ins locally; PDF generation and splicing technology is based on the open source iText component to realize PDF generation, splicing, validity verification, watermark setting and encryption functions, and CA electronic signature technology is based on the Anzhengtong server-side Xinchuang signature middleware to realize OFD or PDF file fast signing on the server side, support concurrent signing of a large number of users, and connect with the business system to realize stamping, personal signature, stamp verification, watermarking, two-dimensional barcode, saddle stamping and multi-page stamping operations, and is compatible with any browser and has online preview function.

[0023] The clusters, object storage, network proxy, message queues and other services that the deployment relies on are all built with stable versions of mainstream open source middleware, and security measures such as access control, identity authentication, and encryption are enabled for correct configuration to improve the security of the software. At the same time, we pay close attention to software vulnerability reports, respond quickly to fix security patches, and update them in a timely manner.

[0024] On the system periphery, the information security system runs through the entire system architecture, formulates security regulations and strategies, and improves the security management mechanism to ensure the security of data and systems and protect user privacy and data integrity.

[0025] In one of the embodiments, the client uses Vue as the front-end interaction framework. Unlike other large-scale progressive frameworks, Vue is an MVVM (Model-View-ViewModel) framework that can be applied layer by layer from the bottom up. Through the ViewModel layer, two-way data binding is performed with the view layer upward, and data interaction is performed with the Model layer downward through interface requests. When the data changes, the view changes accordingly, and when the view changes, the data also changes synchronously, thereby abstracting the user interface functions into different controls, each of which implements its own interaction logic, and different control combinations implement complete page logic.

[0026] In one specific embodiment, the construction project multi-drawing joint review system sets up the survey and design unit module, the construction unit module, the review agency module, the reviewer module and the supervision department module according to the needs of the user group; The survey and design unit module is used by survey and design units to batch convert, electronically sign and upload electronic drawings online through the construction drawing file upload tool, and receive review opinions, respond to drawing rectifications and download qualified drawings; The batch conversion function of the construction drawing file upload tool is as follows: automatically convert each drawing in the electronic drawing into a PDF file, automatically adapt the drawing size, scale, automatically add white edges, automatically correct the font, and name the PDF file according to the drawing number and name; The specific function of electronic signature is as follows: the survey and design unit can stamp the survey report or electronic drawing with the registered engineer's seal and the unit's issuing seal through the PDF standardized signature, and the signatures of different signature companies can be uniformly verified to achieve unified signature and verification; The online upload function uses multi-threading, segmented upload, breakpoint resume and progress display to upload drawings by single project and by profession, and simultaneously record the upload log. If an interruption occurs, re-upload the unuploaded drawing files; for projects that include fire protection and civil air defense review, only one set of drawings is uploaded, and the fire protection and civil air defense drawings are marked from the uploaded project master drawings; When reviewing opinions, structured opinions are presented in a list format. When the survey and design unit double-clicks an opinion, the system automatically opens the problematic drawing and locates the expert's annotation location. When the survey and design unit responds to the revision of the drawings, the revised drawings will not cover the previous round of drawings. Instead, the new version of the drawings will be uploaded after the previous round of drawings, and the replacement relationship of the drawings will be presented in a tree structure, so that the entire process can be traced back. After passing the review, the survey and design unit will batch download a set of drawings or survey reports with a seal of approval and then deliver them to the construction unit.

[0027] The construction unit module is used by the construction unit to register projects, submit projects, supplement materials, track projects, and review review opinions through the project review tool; The construction unit registers the project for review through the project review tool. After the project registration is completed, the survey and design unit shall upload the survey report or design drawings according to the single project, and then the construction unit shall complete the project information and upload the policy review materials, and confirm the submission for review; the system has unified the design of single review projects and multi-review combined projects. The construction unit shall check the construction drawing review type during the initial review and confirm it in the review window. The system will automatically perform intelligent processing on the subsequent process according to the selection of single review and multi-review combined, including whether the process synchronization is controlled, whether the opinions are merged, and whether the qualified drawings are signed separately. If the policy materials provided during the first review are incomplete, it will be regarded as a pre-review project, and the drawing review process will continue. At the same time, the review agency will initiate the material correction, and the construction unit or survey and design unit will re-submit the missing materials. The survey and design units and construction units can track and query the progress of project review, which can display project process, review rounds, survey units, design units, drawing design progress, project submission date, pre-review date, formal acceptance time, project manager, manager contact information, print acceptance form, review conclusion (passed, rectified), opinion summary progress, opinion approval, opinion letter issuance, certificate approval, certificate issuance and other information.

[0028] The review agency module is used for unified review, task allocation, opinion generation, opinion approval, qualified letter reply, qualified drawing signature and unified feedback of the submitted projects. It also includes a project pre-review management unit, which is used to provide early pre-review review services for projects that lack policy materials, including project differentiation management, pre-review project document issuance, pre-review project conversion to formal project and pre-review project formal document supplementation; When the review agency module accepts the review, it will automatically verify the signatures and seals of the uploaded survey reports or design drawings, and automatically detect whether the survey reports or design drawings have passwords, are damaged, and contain potentially dangerous scripts. If the verification passes, the review service window will verify the completeness and accuracy of the project information, technical review materials, and policy review materials. For projects that include fire protection and civil air defense reviews, the fire protection and civil air defense drawings will be quickly searched and viewed. If the verification passes, the review will be formally accepted. If the materials are incomplete, a correction notice will be issued, asking the survey and design unit or construction unit to complete the materials and resubmit for review. After receiving the review task, the review agency manager will allocate the review task according to the reviewer's workload prompted by the system. The system will automatically notify the relevant reviewers and specify the professional reviewers and review time limits. After the reviewer has finished the review, the system automatically generates and merges the review opinions based on the structured expert opinions into a review opinion letter, which is then transferred to the technical director of the institution for review and approval of the opinion letter and approval of the qualified letter, and is stamped with an electronic signature; After the project is reviewed and approved, the system automatically extracts the final version of each drawing to form a complete set of qualified drawings. The review agency stamps the qualified set of drawings with an electronic seal of approval in batches. After the review opinions, review certificates and qualified drawings of the review agency are approved and stamped, they will be fed back to the survey and design unit and the construction unit in real time for online download and use.

[0029] The reviewer module is used by reviewers to make online annotations, compare similar drawings, and measure distance and area through review tools; The review tool provides a separate annotation layer for reviewers to modify the annotations, which will not be merged with the original drawing, and the original drawing will not be changed. The historical comments are permanently associated with the drawing; When comparing similar drawings, the review tool analyzes and compares different versions of drawings based on trace tracking technology, locates the modified content and generates a drawing modification list; For PDF files, the review tool automatically converts the actual distance or area according to the drawing scale set by the user. The web page integrates domestic WebPdf products to realize length measurement, area measurement and perimeter measurement.

[0030] The regulatory department module is used for review project query, review timeliness monitoring, design quality monitoring, review cost statistics, comprehensive chart analysis and statistical summary reports; Review project query includes project overview, single project information, survey report or drawing information, policy review material information, review opinion information, and project review process information query, making the whole process traceable and restorable; Review timeliness monitoring includes the number of days for issuing first-instance opinions, the number of overdue days, the number of days for issuing certificates, the number of review items, the number of overdue items, the proportion of overdue items, the average number of days for issuing review opinions, and the average number of days for issuing certificates. It tracks the review timeliness of each project and review agency, and issues early warnings for abnormal situations. Design quality monitoring includes monitoring the number of violations of mandatory provisions, the number of violations of mandatory standards, the total number of projects, the building area, the total number of violations of mandatory provisions and the average number of violations of mandatory provisions, tracking the design quality of each project and survey and design unit, and issuing early warnings for abnormal situations; Review fee statistics are used to review fees by time, project classification or charging method, and support export to Excel; Comprehensive chart analysis lists a series of key indicators of the timeliness and quality of construction drawing review and evaluation for the review projects, analyzes them from different angles and displays them in charts. The indicators include the total number of projects, review area, investment amount, one-time review pass rate, number of strong clauses violated, average number of strong clauses violated, average number of strong clauses violated per 10,000 square meters, number of overtime projects, proportion of overtime projects, average number of days for review opinions, average number of days for qualified certificates, etc. The system classifies these key indicators from different types of projects such as all, survey, housing construction, municipal administration, and special projects.
