Description

Technical Field

[0001] The present invention belongs to the technical field of engineering coding management, and in particular relates to an automatic coding collaborative management system and method for highway engineering. Background Art

[0002] In existing highway construction management, progress, quality inspection, and measurement tasks are typically completed independently by various business systems, resulting in fragmented information and data fragmentation, making unified coding management and cross-business collaboration difficult. Furthermore, existing systems generally lack standardized processing and dynamic tracking of project data throughout the entire process. Processes such as task status changes, output value statistics, and quality assurance documentation compilation often rely on manual intervention, resulting in low efficiency and error-prone. Furthermore, project output value forecasts and measurement payment audits often rely on empirical judgment or delayed aggregation, failing to proactively identify and control risks. This leads to issues such as misuse of funds and opaque management. Regarding quality management, most current projects rely on manual triggering of quality assurance documentation processes, lacking unified standards and weak information retention capabilities, compromising data integrity and traceability. Furthermore, a real-time mapping mechanism between progress, status, and 3D models between the construction site and the management platform is lacking, making it difficult for managers to keep abreast of the actual on-site situation. Summary of the Invention

[0050] like Figure 1 As shown, a highway engineering automatic coding collaborative management system includes:

[0051] The code generation module 101 is used to generate the engineering division code of the first project based on the five-level engineering division template rules preset in the cloud, and write the engineering division code into the alliance chain system;

[0052] The task management module 102 is used to match the corresponding progress tasks, quality inspection tasks, and measurement tasks from the preset bidding list according to the project classification code, determine the task workload and task status of each task, collect on-site completion data and actual costs, and calculate progress performance indicators and cost performance indicators;

[0053] Among them, the on-site completion data includes: actual engineering quantity and timestamp;

[0054] Task status includes: not started, in progress, completed and accepted;

[0055] Output value statistics and freezing module 103, used to calculate the comprehensive risk index based on the actual engineering quantity, progress performance index and cost performance index, and update the measurement payment freezing status based on the comprehensive risk index;

[0056] Among them, the metering payment freeze status includes: frozen and unfrozen;

[0057] The business trigger module 104 is used to automatically start the quality assurance document compilation process when the task status corresponding to the project classification code changes from in progress to accepted;

[0058] The completion determination module 105 is used to summarize the task status and measurement payment freeze status of the tasks corresponding to the project division code, and automatically update the project status to completed when all tasks corresponding to the project division code have been completed and there is no freeze record;

[0059] Among them, the project status includes: under construction, under acceptance, completed and closed.

[0060] In one embodiment of the present invention, the coding generation module first receives the project unique identifier from the engineering project management interface, and then obtains the preset five-level engineering division template rules through the cloud; the five-level engineering division template rules include the number of five-level coding digits, the meaning of each level and the value range, which correspond to the major engineering categories, sections, divisions, sub-items and sub-items respectively.

[0061] After obtaining the five-level project division template rules, the code generation module splices the five-level code and the last six digits of the current UTC timestamp into the project division code. The splicing method is: , where C represents the project classification code, and W, B, F, X and Z are two-digit decimal numbers, representing the project category, section, division, sub-item and sub-item respectively. Indicates the last six digits of the current UTC timestamp, used to ensure that codes generated in the same second can be distinguished.

[0062] In one embodiment of the present invention, the code generation module further includes:

[0063] A hash calculation unit, used to perform a SHA-256 hash operation on the engineering partition code to generate a hash fingerprint;

[0064] The writing unit is used to write the hash fingerprint, engineering partition code and timestamp into the alliance chain system to verify the integrity and non-tamperability of the engineering partition code; the alliance chain system is a distributed ledger network composed of a number of mutually trusted nodes. Each node maintains a consistent ledger state through a consensus algorithm. Once any write operation is verified by the majority of nodes, it cannot be modified, ensuring the full traceability and tamper-proofness of the encoded data.

[0065] Through the above-mentioned structured process, this embodiment realizes standardization, parsability, full-cycle tracking and distributed trusted evidence storage at the coding level, providing a solid data foundation for subsequent automatic task decomposition, progress and cost management, quality triggering and project closed-loop control.

[0066] In one embodiment of the present invention, the task management module is used to use the project division code as an index, automatically screen out the progress tasks, quality inspection tasks and measurement tasks corresponding to the project division code in the pre-imported bidding list, and calculate the task workload and track the status of each task. Specifically, this embodiment obtains the design engineering quantity and preset complexity coefficient of each task by reading the task information matching the project division code in the preset bidding list, and obtains the task workload by multiplying the design engineering quantity and the complexity coefficient.

[0067] In one embodiment of the present invention, the total earned value is obtained by accumulating the product of the actual work quantity and the complexity coefficient of each task;

[0068] The planned value is obtained by multiplying the task workload of each task by the preset planned completion ratio, and the total planned value is obtained by adding up the planned values ​​of each task.

[0069] The total earned value is calculated by comparing it with the total planned value to obtain the progress performance index. The calculation formula of the progress performance index is: SPI represents the progress performance index, which is used to reflect the degree of advance or lag of the actual progress relative to the planned progress. N represents the total number of tasks, which is 3 in this embodiment. i represents the task index. represents the actual engineering quantity of the i-th task, represents the complexity coefficient of the i-th task, represents the design engineering quantity of the i-th task, Indicates the preset planned completion ratio of the i-th task;

[0070] The cost performance index is obtained by calculating the ratio of the total earned value to the total cost obtained by adding up the actual costs of each task. The calculation formula of the cost performance index is: , CPI stands for Cost Performance Index, which is used to reflect the savings or overruns of actual costs relative to the completed value, represents the actual cost of the i-th task.

[0071] Through the above process, the task management module can realize an integrated closed loop from code-driven task decomposition, on-site data collection, workload and cost summary, to progress and cost performance evaluation, providing a data basis for subsequent output value statistics and freezing.

[0072] In one embodiment of the present invention, the specific steps of calculating the comprehensive risk index include:

[0073] S201, calculate the ratio of the absolute difference between the total earned value and the total planned value to the total planned value to obtain the output value deviation coefficient; the output value deviation coefficient reflects the systematic gap between the degree of output value completion and the planned expectation;

[0074] S202, by comparing the difference between the progress performance index and the cost performance index and 1, the progress deviation coefficient and the cost deviation coefficient are obtained respectively; when the progress performance index is greater than 1, the progress deviation coefficient is positive, indicating that the progress is ahead of schedule; when the progress performance index is less than 1, the progress deviation coefficient is negative, indicating that the progress is behind schedule; similarly, a positive value of the cost deviation coefficient indicates cost savings, while a negative value indicates cost overruns;

[0075] S203 calculates a comprehensive risk index based on the output value deviation coefficient, schedule deviation coefficient, and cost deviation coefficient, along with preset weights. These preset weights can be flexibly configured based on factors such as project type and management priorities. For highway projects, the output value deviation coefficient is weighted at 0.4, while the schedule deviation coefficient and cost deviation coefficient are both weighted at 0.3, for a total of 1. This process integrates multi-dimensional deviation information from the project into a single quantitative indicator, intuitively reflecting the overall risk level and providing a clear basis for subsequent determination of whether to trigger a metered payment freeze.

[0076] In one embodiment of the present invention, if any of the following conditions is met, the meter payment freeze status is updated to frozen:

[0077] The comprehensive risk index exceeds the preset comprehensive threshold;

[0078] The output value deviation coefficient exceeds the preset single item threshold;

[0079] The completion status of the sub-item factory quality assurance documents corresponding to the project classification code is incomplete.

[0080] Specifically, after calculating the comprehensive risk index, it is compared with the preset comprehensive threshold. If the comprehensive risk index exceeds the preset comprehensive threshold, it means that the overall risk of the project in terms of output value, schedule, and cost has exceeded the acceptable range. At this time, the freezing mechanism is triggered, and the measurement payment freeze status is updated to frozen, suspending the measurement payment process under the corresponding project classification code;

[0081] If the output value deviation coefficient exceeds the preset individual threshold, it means that the deviation between the total earned value and the total planned value has reached a level that requires key control. Even if the comprehensive risk index does not exceed the limit, a freeze must be initiated.

[0082] Regarding the conditions for determining the completion status of quality assurance documents, the present invention associates the engineering division code with the corresponding sub-project quality assurance document management module in real time to verify whether the completion status of the quality assurance documents of the sub-project under the code is incomplete. If it is determined to be incomplete, freezing will be triggered regardless of whether the comprehensive risk index and the output value deviation coefficient meet the standards. For example, when the hidden project acceptance record has not been signed in the quality assurance documents corresponding to the engineering division code of a bridge foundation sub-item, the system recognizes that the completion status of the sub-item quality assurance documents is incomplete, and automatically updates its measurement and payment freeze status to frozen.

[0083] Through the above-mentioned independent judgment mechanism of multiple conditions, the system can achieve precise control of metering payments from three dimensions: overall risk, key indicator deviation and compliance, ensuring that payment operations are carried out under the premise of controllable risks and complete information, and effectively avoiding management loopholes caused by risk accumulation or missing information.

[0084] In one embodiment of the present invention, the project hierarchical structure fields contained in the engineering division code, including project number, section number, division number, sub-item number, and sub-item number, are parsed and matched with pre-stored attribute fields of components in a pre-set digital 3D engineering model. These attribute fields are structured information preset in the BIM model for the component, including but not limited to: the project to which the component belongs, division name, component type, component location number, component ID, etc. Based on the semantic consistency and value matching rules between these fields, the component object corresponding to the engineering code is identified.

[0085] Furthermore, this embodiment establishes a binding relationship between successfully identified and matched components and project division codes. Specifically, the project division code is written into the target component's external identification field, forming a one-to-one code-component mapping relationship. This binding relationship enables data integration between the business system and the 3D model, allowing task status, progress performance indicators, and payment freeze status related to the project division code to be synchronized to the model in real time, dynamically reflecting the status of each component in the 3D view.

[0086] The establishment of the above binding relationship not only ensures the traceability and uniqueness of the engineering division code at the model level, but also provides basic support for the integrated visual management of quality progress measurement, further enhancing the relevance, consistency and management efficiency of system data.

[0087] In one embodiment of the present invention, the business trigger module is used to automatically start the subsequent quality assurance document compilation process based on the change of the task status associated with the project division code. Specifically, when it is detected that the task status corresponding to the project division code has changed from in progress to accepted, indicating that the sub-project has been completed and passed the acceptance, and meets the conditions for entering the quality document compilation stage, the business trigger module automatically performs the following operations: on the one hand, it generates a quality assurance document task list corresponding to the project division code, including quality inspection reports, hidden project acceptance records and other conventional quality assurance materials; on the other hand, it automatically assigns a responsible role, a filling template and a deadline for each document task, and at the same time pushes the compilation task to the quality assurance person's workbench to enter the system's quality assurance document management process.

[0088] Through the above method, the present invention can automatically start the compilation of quality assurance data according to the task status changes driven by the project division code without manual operation, ensure the timely generation and archiving of key documents, improve the quality management efficiency and system compliance of the entire highway project process, and have a high degree of automation and traceability.

[0089] In one embodiment of the present invention, the completion determination module specifically comprises the following steps:

[0090] S301, calculating the ratio of the number of completed tasks to the total number of tasks to obtain a task completion ratio, wherein tasks with a status of completed or accepted are both considered completed tasks;

[0091] S302: Summarize the metering payment freeze status of each task to obtain a task freeze aggregate value, where frozen is represented by 1 and unfrozen is represented by 0. The task freeze aggregate value is used to indicate whether there is a frozen task.

[0092] S303: When the task completion ratio is 1 and the task freeze aggregation value is 0, the project status is updated to completed.

[0093] Through the above steps, this embodiment realizes the automatic judgment and status update of the project completion status, avoids the delay and error of manual confirmation, helps to trigger subsequent archiving, report generation and other processes in the business system, and improves the automation and reliability of project management.

[0094] In one embodiment of the present invention, a method for collaborative management of automatic coding of highway projects is also provided, comprising the following steps:

[0095] S401: Generate the engineering division code for the first project based on the five-level engineering division template rules preset in the cloud, and write the engineering division code into the alliance chain system;

[0096] S402: Match the corresponding progress tasks, quality inspection tasks, and measurement tasks from the preset bidding list based on the project classification code, determine the task workload and task status of each task, collect on-site completion data and actual costs, and calculate progress performance indicators and cost performance indicators;

[0097] Among them, the on-site completion data includes: actual engineering quantity and timestamp;

[0098] Task status includes: not started, in progress, completed and accepted;

[0099] S403: Build an output value prediction model based on a long short-term memory network based on the progress performance indicator, the cost performance indicator, and the historical output value data, and output the predicted output value. The predicted output value is used to update the metering payment freeze status;

[0100] Among them, historical output value data includes: daily earned value, daily planned value and actual cost;

[0101] The meter payment freeze status includes: frozen and unfrozen;

[0102] S404: When the status of the task corresponding to the project classification code changes from in progress to accepted, the quality assurance document preparation process is automatically started;

[0103] S405: Summarize the task status and measurement payment freeze status of the tasks corresponding to the project division code, and automatically update the project status to completed when all tasks corresponding to the project division code have been completed and there is no freeze record.

[0104] Among them, the project status includes: under construction, under acceptance, completed and closed.

[0105] It should be noted that the intervals and thresholds are set for ease of comparison. The threshold size depends on the amount of sample data and the cardinality set by those skilled in the art for each set of sample data, as long as it does not affect the proportional relationship between the parameter and the quantized value. Furthermore, the above formulas are all dimensionless numerical calculations. These formulas are derived from software simulations of the most recent real-world conditions using large amounts of data. The preset parameters in these formulas are set by those skilled in the art based on actual conditions.

[0106] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
