Description

A blockchain-based engineering project management audit system

Technical Field

The present invention relates to the technical field of engineering project management, and in particular to an engineering project management audit system based on blockchain.

Background Art

Engineering project management audit is an independent, objective and comprehensive review and evaluation of engineering project management activities to ensure that the engineering project is carried out in accordance with the predetermined goals, plans, budgets and quality standards. This audit process aims to reveal possible problems in engineering project management, put forward improvement suggestions, help organizations optimize resource allocation and improve project management efficiency.

However, in actual applications, since blockchain technology can only ensure the authenticity and reliability of engineering project data after it is written into the blockchain, it is impossible to judge the accuracy of engineering project data before it is written. This requires auditors to make comprehensive judgments based on other evidence and information in addition to relying on blockchain data when conducting audits. However, traditional manual audits are difficult to run in today's audit environment with huge data processing volumes. Therefore, intelligent identification, judgment and repair of engineering data in the early stage of the audit are particularly important.

DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Embodiment 1, please refer to FIG. 1 , a blockchain-based engineering project management audit system described in this embodiment includes:

The collection and quality improvement module is used to collect actual single project items, where the actual single project items include the preliminary bidding information, construction completion information and project settlement information of the project;

The information interaction module is connected to the collection and quality improvement module, and is used to build a virtual model based on the actual engineering project, and to overlay and interact with the initial model built by reporting a single engineering project, establish multiple interconnection points between the virtual model and the initial model, compare the difference data between the virtual model and the initial model, and use the corresponding interconnection points of the difference data as interaction data points;

The base station module is connected to the information interaction module, and a signal base station is set based on the interconnection point, and multiple signal base stations are connected to obtain an interactive network;

The difference processing module is connected to the base station module and is used to evaluate the difference level of the interaction data points based on the difference auxiliary components configured by the signal base station, and send the difference data corresponding to the interaction data points that do not meet the preset difference level from the signal base station to the patch correction package receiving end to modify the signal source;

The patch repair module is connected to the difference processing module, and the patch correction package receives the modification signal source to split and repair the corresponding difference data;

The transmission module is connected to the patch repair module, and transmits the difference data repaired by the patch correction package to the initial model through the signal base station of the virtual model and the signal base station in the corresponding initial model, and inputs it into the pending blockchain.

It is further explained that blockchain technology has obvious advantages in the application of project management auditing and can significantly improve the progress of the project. However, in actual applications, blockchain technology can only ensure the authenticity and reliability of project data after it is written into the blockchain, and cannot judge the accuracy of project data before it is written. This requires auditors to make comprehensive judgments based on other evidence and information in addition to relying on blockchain data. However, traditional manual auditing is difficult to operate in today's auditing environment with huge data processing volume. In this application, the audit data of reported project audits before being written into the blockchain is pre-verified. First, accurate actual single project data is collected to build a virtual model and report the structure of the single project. An initial model is built for model superposition and interaction, so as to establish multiple interconnection points and set up signal base stations on them. When differential data appears at a certain interconnection point, the corresponding signal base station sends a modification signal source to attract the correction patch package flowing in the interactive network, and the correction patch package splits the individuals corresponding to the differential data for repair. After the repair, the signal base station feeds back to the virtual model, and the virtual model then synchronously modifies the initial model of the corresponding signal base station and inputs it into the blockchain, ensuring the accuracy and reliability of the data before the audit data of the reported engineering project is written into the blockchain. At the same time, the flow splitting and repairing method is used, which does not occupy the data communication of the interactive network and can quickly repair the differential data, thereby promoting the operation and maintenance efficiency of the project engineering audit processing.

In one embodiment, the acquisition quality improvement module includes:

Extraction unit, used to obtain preliminary bidding information, construction completion information and project settlement information and organize them to obtain the project process;

The optimization unit is used to automatically retain one of the duplicate data and delete other duplicate items for storage to obtain a data management library.

To further explain, the preliminary bidding materials here mainly include bidding documents, tender documents, qualification certification documents, technical solution documents, commercial quotation documents and bidding clarification and Q&A record documents; the construction completion materials mainly include construction drawings, construction contracts, construction records, quality inspection reports, completion drawings and completion acceptance reports; the project settlement materials mainly include settlement statements, bills of quantities, change certificates, material and equipment lists and settlement audit reports. For the above preliminary bidding materials, construction completion materials and project settlement materials (it is necessary to ensure that the collected materials are free of fraud risks. If there is a fraud problem, not only do they need to be collected again, but the project will also be marked as fraudulent, and will be suspended and reviewed before entering the subsequent audit processing system), the content format of all materials is unified and standardized, including text format, date format, numerical format, etc., to ensure the consistency and readability of the materials, so as to sort out the specific project process, and then identify the duplicate materials, automatically retain one of them and delete other duplicates, establish a data management library for storing, classifying and indexing all optimized materials, and the data management library supports efficient retrieval and query functions, so that the required materials can be quickly found when needed.

In one embodiment, the information interaction module includes:

The model building unit builds the project flow structure based on the actual single project to obtain a virtual model, and builds the project flow structure based on the reported single project to obtain an initial model;

The interaction unit extracts a plurality of project information corresponding to the virtual model and the initial model, and uses corresponding positions of the plurality of project information in the virtual model and the initial model as a plurality of interconnection points;

The difference determination unit is used to compare the project information corresponding to the virtual model and the initial model, and use the project information with differences as difference data and the interconnection points corresponding to the difference data as interaction data points.

It is further explained that a virtual model is constructed by the project process of an actual single engineering project, and an initial model is constructed by reporting the project process of a single engineering project. The virtual model and the project process corresponding to the initial model are superimposed and interacted. The project process is essentially the information of each project from the beginning to the end of the project in the single engineering project, wherein the project information is the information that needs to be compared and modified between the virtual model and the initial model, and the position of each project information is used as an interconnection point, each interconnection point represents an interaction point between the virtual model and the initial model, and by determining these interconnection points, the interaction relationship between the two models can be clearly reflected. When difference data appears in the project information corresponding to an individual interconnection point, the difference data that appears is used as an interaction data point on the corresponding interconnection point, and the specific position of the difference data in the virtual model is determined by the interaction data point. Among them, if there is no difference data in the project information corresponding to the interconnection point, it means that the data of each project information is accurate, so that the difference identification of the difference processing module and the split repair of the patch repair module can be directly skipped, and the final transmission module can be directly entered and uploaded to the blockchain.

In one embodiment, the base station module comprises:

A channel building unit is used to build a transmission channel between multiple signal base stations configured at corresponding interconnection points;

The guidance unit is used to formulate navigation point information of the transmission channel, wherein the navigation point information includes signal base station conduction information and channel number information corresponding to the signal base station conduction information.

It is further explained that an interactive network is obtained by a signal base station and a transmission channel connecting the signal base station. The transmission channel is a wireless channel, and the transmission channel can be used to share base station information to ensure that all signal base stations in the interactive network can obtain signals and data. The transmission channel itself also has channel maintenance and management. In the communication network, the transmission channel is monitored in real time through an existing monitoring system, including regular detection and recording of key parameters such as signal strength, transmission rate, and delay. The transmission channel is also provided with navigation point information and channel number information. The navigation point information provides direction guidance for data flow in the transmission channel to improve signal transmission efficiency and stability, while the channel number information assigns a channel number to the transmission channel, so that subsequent patch correction packages can plan the shortest arrival path in the interactive network constructed by the signal base station and the transmission channel according to the channel number information to reach the location of the interactive data point that releases the modified signal source, and repair the corresponding difference data.

In one embodiment, the difference processing module includes:

An evaluation unit, configured to evaluate the difference level of the corresponding difference data based on the signal base station and classify the difference data into corresponding level intervals, wherein the level intervals are a minor level interval, a general level interval, and a major level interval;

The signal releasing unit is used to send the difference level higher than and equal to the general level interval to the corresponding signal base station to modify the signal source.

It is further explained that the difference level of the interaction data points is evaluated through the established signal base station, and the project information is used as the initial base to judge the difference level of the difference data, wherein the minor level interval represents that the error rate of the project information of a single engineering project is lower than 5% compared with the initial base; the general level interval represents that the error rate of the project information of a single engineering project is in the range of 5%-15% compared with the initial base; the major level interval represents that the error rate of the project information of a single engineering project is higher than 15% compared with the initial base, wherein the minor level interval does not need to be reported and can be processed directly; the general level interval does not meet the requirements, and is repaired with a patch correction package and reported for decision in real time; the major level interval also does not meet the requirements. If the error direction is a concentrated small error, the processing result is the same as the general level interval. If the error direction is a concentrated large error, the patch correction package can be modified first, and then enter manual review, and finally the blockchain can be uploaded after a double decision.

In one embodiment, the patch repair module includes:

An attraction unit, used for moving the patch correction package attracted by the modification signal source to contact the corresponding interaction data point;

The splitting unit is used to split the patch correction package data and contact the interactive data points corresponding to the difference data.

The splitting unit comprises:

Individual unit, the patch correction package is a combination of multiple types of individuals, where the defect types of the multiple types of individuals are the same as the defect types of the difference data;

A path planning unit, used to plan the shortest arrival path between the interaction data point corresponding to the modification signal source and the patch correction package;

A category identification unit, used to identify the defect type of the difference data corresponding to the interaction data point, and split the patch correction package into corresponding type individuals based on the defect type of the difference data;

The patching unit transmits the type individuals to the interaction data points based on the shortest arrival path and patches the corresponding difference data.

To further explain, firstly, a patch correction package flowing in the interactive network is utilized. When the corresponding signal base station of the difference data sends a modification signal source, the modification signal source acts as an attraction end to release an attraction signal to the patch correction package. The patch correction package receiving the attraction signal flows through the interactive network to the location of the modification signal source. Among them, a transmission channel which is one of the components of the interactive network can provide flow direction guidance for the patch correction package, and use its channel coding information to plan the shortest arrival path from the modification signal source, and use the path to reach the location of the signal base station corresponding to the modification signal source. The arrived patch correction package first performs category analysis on the difference data released by the modification signal source, and then compares it with the individual categories in the patch correction package. After the comparison is completed, the individual categories of the corresponding abnormal data will be split, and transmitted by the shortest arrival path of the patch correction package and the contacted signal base station (the shortest arrival path has two functions, one is the path for the patch correction package to reach the modified signal source, and the other is the path for the individual category to reach the abnormal data corresponding to the signal base station after the patch correction package is split), and finally integrated into the signal base station where the difference data appears, to modify the difference data and feedback to the interconnection point corresponding to the signal base station, and finally act on the virtual model, and the patch correction package can also absorb the category individuals subsequently injected into the transmission channel, so as to keep the different patch category data continuously existing to form a combined correction patch package.

In one embodiment, the transmission module includes:

A data improvement unit, used for transmitting the difference data after the patch correction package is repaired from the corresponding signal base station to the virtual model and modifying the corresponding initial model;

The transmission unit is used to transmit the reported single engineering project corresponding to the modified initial model to the blockchain in one direction.

It is further explained that a patch correction package is used to repair the difference data corresponding to the signal base station. After the repair is completed, the status of the signal base station will be fed back to the virtual model in real time through the interconnection point, so as to update and correct the erroneous data in the virtual model. This process is the virtual model improvement. In the process of improving the signal base station corresponding to the virtual model, due to the interactive superposition relationship, these repair operations will also be information-equivalently repaired with the corresponding signal base station in the initial model, which means that every correction in the virtual model will be automatically mapped to the initial model to ensure data synchronization between the two. When the signal base station corresponding to the virtual model is repaired, the corresponding signal base station in the initial model will also take over these repairs. This ensures that the data of the signal base station remains consistent both in the actual operating environment and in the virtual simulation environment. Finally, in order to verify the accuracy and completeness of the repair, a global verification will be performed through the virtual model and the initial model. This double verification mechanism ensures data consistency and accuracy during and after the repair, thereby greatly improving the stability and reliability of the system.

The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
