Description

Technical Field

[0001] This invention relates to the field of construction management technology, and in particular to a field factory management system based on assembly elements. Background Technology

[0002] With the development of prefabricated buildings, the concept of factory construction has been gradually introduced into construction sites, breaking down the complex construction process into standardized work links and forming a coverage area with tower cranes as the core. However, in actual construction, the project site is not divided reasonably enough, the task allocation lacks a unified standard, and the coordination between personnel, equipment, components and processes has not been effectively connected, resulting in high complexity of site management, low task execution efficiency, and a lack of quantitative verification and evaluation mechanisms for the construction process.

[0003] Existing technologies suffer from disconnects in assembly element segmentation, factory design, task allocation, and process verification, making it difficult to achieve closed-loop management of the entire construction site process. This is particularly pronounced in environments with multiple tower cranes operating simultaneously, where overlapping assembly element boundaries, task conflicts, and schedule imbalances become significant issues. Furthermore, safety inspections, quality acceptance, and schedule comparisons often rely on manual experience, lacking systematic support and hindering the formation of objective, comprehensive evaluations.

The on-site factory management system based on assembly elements according to claim 7, characterized in that, The progress comparison unit includes: The plan extraction sub-unit is used to extract the planned start time of the corresponding task for each trade within the assembly unit from the work task list. With the planned end time Actual extraction subunit: Used to extract the actual start time of the corresponding task from the task record unit. Compared with the actual end time Time difference calculation subunit: Used to calculate the time deviation value for each task, the formula is: Wherein, ΔT represents the difference between the actual time taken for the task and the planned time taken; Deviation aggregation sub-unit: used to perform weighted averaging of ΔT for all tasks under the same assembly element, generating schedule deviation information for the corresponding assembly element.

9. The on-site factory management system based on assembly elements according to claim 7, characterized in that, The comprehensive evaluation module includes an indicator collection unit, a scoring calculation unit, and a report generation unit; wherein: Indicator collection unit: Used to receive safety inspection results, quality judgment results and schedule deviation information output by the process verification module, and collect and organize them according to assembly element number to form a structured set of verification indicators; Scoring calculation unit: Used to calculate the weighted scores of the collected indicators according to the preset evaluation weight system, output the execution score value of each assembly element, and mark the score level; Report generation unit: Used to summarize the scoring results, anomaly records and indicator details of each assembly element to generate a comprehensive evaluation report, including assembly element number, performance score, scoring level, main issues and suggested improvement measures.

10. The on-site factory management system based on assembly elements according to claim 1, characterized in that, The scoring calculation unit includes: Indicator standardization sub-unit: Used to normalize the verification indicator value of each assembly element into a score value, which is denoted as the safety score S. a Quality Score S q Progress Score p All scores are standardized to a 0-100 range; Weighted Invocation Subunit: Used to invoke preset evaluation weight coefficients according to the type of assembly element, denoted as safety weight W. a Quality weight W q Schedule weight W p Satisfying W a +W q +W p =1; The scoring calculation sub-unit calculates the execution score of the assembly element based on a weighted formula, which is: S z =W a ·S a +W q ·S q +W p ·S p , among which, S z This indicates the final comprehensive score for the assembled components; Level determination subunit: used to determine the level of S according to preset level standards. z The rating system is divided into levels; specifically, when S... z When ≥90, it is classified as Grade A; when 75≤S z When S < 90, it is classified as Grade B; when 60 ≤ S z When <75, it is classified as Grade C; when S z When the value is less than 60, it is classified as Level D.
