Description

Technical Field

[0001] This invention relates to the field of digital management technology, specifically to a digital management system and method for green construction. Background Technology

[0002] In the field of green construction, the development and application of digital management systems have become important means to improve construction efficiency, monitor resource consumption, and reduce environmental impact. Currently, such systems typically rely on multiple data sources for information collection, such as construction personnel operation records, material usage records, and equipment operation records, to form preliminary monitoring of the construction process.

[0003] However, while existing technologies can handle basic record information, several core and niche shortcomings remain in resource load calculation. First, due to the continuity between construction processes and the complexity of resource handover, existing methods struggle to accurately construct cross-process temporal relationships. This results in resource usage calculations failing to effectively reflect the actual impact of preceding processes on subsequent processes, leading to biased resource assessments. Second, the lack of a reliable mechanism to ensure the irreversible forward transfer of resources along the process sequence during resource usage accumulation makes resource load data prone to breaks or errors during inter-process transmission, failing to meet the continuity and accuracy requirements of green construction standards for resource consumption. These interconnected problems collectively limit the ability of digital management systems to achieve efficient and accurate resource management in green construction. Summary of the Invention

[0004] Based on the above-mentioned technical problems, this invention proposes a digital management system and method for green construction buildings.

[0005] A digital management system for green construction includes: The record unification module unifies the format and standardizes the values ​​of the original records, and associates them with the corresponding process information in the construction progress document to form a preliminary record set. The process location module uses the process time interval and resource list in the construction progress document as constraints to uniquely assign the records in the preliminary record set to the corresponding process according to time and source attributes, forming a process record sequence; The time sequence association module establishes a one-way time association across processes within the process record sequence based on the process continuity relationship in the construction progress document; forming a deterministic mapping relationship between the records of preceding and subsequent processes; The resource load generation module calculates the resource usage of each record in the process record sequence using a three-stage incremental generation method: It obtains the corresponding source records of the preceding process using unidirectional time association, extracts the source attribute, time continuity attribute, and inherited attribute of the preceding process as three basic quantities, performs combination operations in a predetermined order to generate a weighted recombination, and then performs weighted operations on the record value, the time difference of similar records, and the value difference of source records of the preceding process with the corresponding components of the weighted recombination. The sum of the three weighted results forms the incremental contribution of the record. The incremental contributions of all records in the process record sequence are accumulated in chronological order to obtain the total usage of the process. If there are resource handover items in the construction progress document, the process resource usage of the previous process is injected into the initial quantity of this process according to the document's specifications, realizing the irreversible forward transmission of process resource usage along the process sequence. The results output module compares the resource usage of each process based on the process information in the construction progress document and the threshold of green construction specifications, and outputs clear management results.

[0006] As a further technical solution, the system performs in-depth processing on the preliminary record set through the process positioning module. Using the time intervals and resource lists clearly defined in the construction progress document as constraints, it performs attribute analysis on each record in the preliminary record set. Specifically, it compares the source attributes, precise timestamps, and field hierarchy information generated by the previous module of each record with the predetermined time intervals of each process. For cases of overlapping times or sources caused by the actual complexity of construction, the records are sorted hierarchically according to the priority of resource requirements, serving as the core basis for determining the unique process to which a record belongs. During the sorting process, subtle time differences between records and inheritance relationships between fields are adjusted and logically corrected line by line to ensure the accuracy of the attribution determination. After determining the attribution of all records, the scattered records are reordered according to the physical execution order of the processes, generating a well-structured process record sequence containing continuous time sequences, clear source identifiers, and unique process identifiers. This transforms the disordered on-site data flow into an ordered data set corresponding one-to-one with the construction processes.

[0007] As a further technical solution, the system uses a temporal association module to construct an initial sequence table of processes within the sorted process record sequence, based on the sequential relationship of processes defined in the construction progress document, as the association benchmark. Subsequently, for each record in the process record sequence, a preceding record retrieval process is initiated to locate and extract preceding process records that are continuous in time and source. This process involves in-depth analysis of the extracted temporal continuity attributes and key inherited fields. The temporal association module analyzes and corrects the specific time difference, subtle differences in source attributes, and consistency of inherited fields between preceding and current records, thereby establishing a unidirectional, deterministic temporal association between preceding and following process records. This unidirectional temporal association ensures that the preceding process record is logically prior to its following process record, and that key inherited information is accurately transmitted without loss. This association is solidified in the sequence in the form of a deterministic association identifier, so that each record in the sequence can clearly point to its preceding process record, while fully preserving traceable inherited attributes and temporal continuity information.

[0008] As a further technical solution, the system's resource load generation module adopts an innovative three-stage incremental generation method to calculate the resource usage of each record in the process record sequence. Through the unidirectional time association established by the aforementioned time sequence association module, it obtains the preceding process records corresponding to the current record. Then, it extracts three key dimensions from these preceding process records as the basis for calculation: source attribute, time continuity attribute, and preceding process inheritance attribute. These three basic dimensions are combined and calculated in a predetermined order to generate a weighted reassembly that dynamically reflects the context of the current record. Subsequently, it combines the current record's own value, the time difference with similar records, and the value of the preceding process records. The three numerical differences are weighted and calculated with the corresponding components in the weighted reorganization. The sum of the three weighted results gives the incremental contribution of the record to the resource usage of this process. After calculating the incremental contribution of all records in the process record sequence, these incremental contributions are accumulated in chronological order to obtain the total resource usage of the process. In particular, when there is a clear definition of resource handover items in the construction progress document, the system will inject the total resource usage finally calculated by the previous process into the initial amount of this process in strict accordance with the method and proportion specified in the construction progress document, ensuring that the resource usage of the process can be irreversibly passed forward along the process sequence.

[0009] As a further technical solution, the three-stage incremental generation method dynamically and adaptively generates weight groups when forming the incremental contribution of each record. This method dynamically adjusts the order of the three basic quantities in the combined operation and their respective allocation ratios within the weighted group based on the numerical change trend of preceding source records, the time interval ratio between the current record and source records, and the matching degree of inherited fields among different records. This dynamic adjustment allows the final weighted group to more specifically reflect the unique impact of each specific record in resource calculation. Each weighted component generated in this way is then weighted one by one with the current record value, the time difference between similar records, and the numerical difference between preceding source records. Simultaneously, to more accurately handle potential differences between preceding and current records, this method adjusts the actual influence of each weighted component on the final incremental contribution through correction coefficients, thereby improving the accuracy and robustness of the calculation.

[0010] As a further technical solution, the calculation process of the correction coefficient is a refined field-by-field processing flow. This coefficient mainly targets the differences between the previous source record and the current record in three key aspects: differences in temporal continuity, differences in source attributes, and differences in inherited fields. During the calculation, the time interval ratio, the matching degree of the previous inherited fields, and the difference in source attributes are normalized field by field in turn to eliminate the influence of different dimensions. Then, according to the inherent logical order of the fields within the record, the normalized results are accumulated item by item to finally generate a comprehensive correction coefficient. When calculating the incremental contribution of a record, this correction coefficient is multiplied by the corresponding component in the aforementioned weighting reorganization, thereby achieving the purpose of dynamically adjusting the contribution value of each record according to the specific differences between records. This further ensures that after the incremental contribution calculation of all records in the process record sequence is completed and accumulated in sequence to form the total usage of the process, the final result can more realistically reflect the resource consumption status. Similarly, when there are resource handover items, the total usage obtained by this precise calculation in the previous process will be injected into the initial amount of this process, realizing the irreversible forward transmission of resource usage with high fidelity along the process sequence.

[0011] As a further technical solution, the system's output module undertakes the final management decision support function. Based on the detailed information of each process defined in the construction progress document, such as process type, resource budget, and preset green construction standard thresholds, this module compares the process resource usage calculated by the resource load generation module from multiple dimensions, including trend analysis and compliance assessment. Based on the comparison results, the module outputs clear and actionable management results, such as resource overrun warnings, process efficiency assessments, and green construction compliance status, to guide on-site management and decision-making in an intuitive way.

[0012] A digital management method for green construction buildings includes: The original records are standardized in format and numerical values, and then linked with the corresponding process information in the construction progress document to form a preliminary record set. Based on the time intervals of the construction progress documents and the resource list as constraints, the records in the preliminary record set are uniquely assigned to the corresponding processes according to their time and source attributes, forming a process record sequence; Based on the sequential relationship of the construction progress documents, establish a one-way time association across processes within the process record sequence; form a deterministic mapping relationship between the records of preceding and subsequent processes; For each record in the process record sequence, a three-stage incremental generation method is used to calculate the process resource usage: First, the corresponding preceding process source record is obtained using unidirectional time association. The source attribute, time continuity attribute, and preceding process inheritance attribute are extracted as three basic quantities. These are then combined in a predetermined order to generate a weighted recombination. Next, the record value, the time difference between similar records, and the value difference between preceding process source records are weighted and calculated with the corresponding components of the weighted recombination. The sum of these three weighted results forms the incremental contribution of the record. The incremental contributions of all records in the process record sequence are accumulated in chronological order to obtain the total usage of the process. If the construction progress document contains resource handover items, the process resource usage of the previous process is injected into the initial quantity of this process according to the document's specifications, achieving irreversible forward transmission of process resource usage along the process sequence. Based on the process information in the construction progress document and the threshold of green construction specifications, the resource usage of each process is compared and a clear management result is output.

[0013] This invention provides a digital management system and method for green construction buildings, which has the following beneficial effects: 1. The invention solves the problem of low data quality caused by inconsistent data formats and weak correlation by processing multi-source heterogeneous original records and achieving automatic alignment with process information, thereby improving the ability of original data to be transformed into a high-quality set of process records with unified semantics and complete traceability information.

[0014] 2. This invention establishes a one-way time correlation across processes and adopts a three-stage incremental generation method to realize the irreversible forward transmission of resource usage, which solves the technical problem of being unable to accurately track cross-process resource flow and causing resource assessment deviation. It improves the temporal accuracy and continuity of resource usage calculation and achieves a breakthrough in the transformation of construction resources from static statistics to dynamic process management.

[0015] 3. By introducing dynamic weight adjustment and correction coefficients into the three-stage incremental calculation, this invention improves the adaptability and reliability of resource load calculation in real-world scenarios, ultimately achieving high-fidelity digital management of green construction resource consumption. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the process of the present invention. Detailed Implementation

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] refer to Figure 1 The system's data input consists of three sources: personnel operating system, material recording system, and equipment operation system. Each original record retains its source format before being input into the unification module, which may be text stream, semi-structured data, or tabular data. The unification module reads each record one by one into the processing flow. The record unification module constructs a unified internal data structure upon data entry; this structure includes record number, source attribute, event time, field set, and hierarchical attribute; the field set exists in key-value pair format, and the record unification module performs standardization according to the following mechanism: First, the time field is extracted and transformed. The record unification module scans the character content of the original record and locates the character groups containing year, month, day, hour, minute, and second features. After locating, they are rearranged according to the system's specified format so that the time field of all records adopts the same time format. If the original record contains multiple time segments, the record unification module determines the main time field based on the source attribute of the record. For example, for personnel operation records, the time of action is taken, and for equipment records, the start time of operation is taken.

[0019] Secondly, numerical fields are extracted and units are standardized. For fields such as specifications, quantity, and weight that appear in material records, the record standardization module parses the numbers in the fields and standardizes them into fixed units. When processing, the module establishes type tags for numerical fields, which are used by subsequent modules to determine the characteristics of the fields.

[0020] Finally, the fields are classified semantically; the record unification module marks each field as a basic field, extended field, or context field according to its meaning; for example, fields representing personnel actions are marked as basic fields, fields representing material properties are marked as extended fields, and fields describing equipment operating status are marked as context fields; the classification process is completed by matching field keywords with the field meaning table.

[0021] After completing the above steps, the record unification module creates a temporary index table for each record. The temporary index table contains field hierarchy, main field set, and potential dependency information between records, which is used for subsequent process location and time sequence association construction. The unification result is output in the form of a structured record set, and each structured record contains a set of fields in a unified format.

[0022] The process location module reads the process definition from the construction progress document; each process contains two basic pieces of information, namely the operation time interval and the resource list; the process location module calculates the process affiliation of the record based on the event time field and source attribute field in the structured record.

[0023] Process location involves two determination steps. The first step is time interval determination. The process location module reads the event time field of each record and compares it with the time interval of all processes. If the event time is within the time range of a certain process, then that process becomes a candidate process set. The second step is resource attribute determination. The process location module reads the source attribute field of the record and compares it with the resource list of the candidate processes. When the source attribute is completely consistent with the process resource list, it is confirmed as the process belonging.

[0024] For records covering multiple process time periods, such as equipment operation records spanning the time boundaries of two consecutive processes, the process location module does not use average division, but instead uses resource attribute consistency as the main criterion; if the equipment is defined in the resource list of a certain process, then the record is directly assigned to that process.

[0025] The process location module ultimately adds a process number field to each record in the structured record set and sorts the records of the same process according to the event time; the sorted records form a process record sequence.

[0026] The task of the time sequence association module is to construct an irreversible unidirectional time-related link between processes, enabling subsequent process records to identify their corresponding preceding records. This module reads the sequence relationship array of processes in the construction progress document to determine the process progression direction that source information should follow. The time sequence association module traverses based on the process sequence. For each subsequent process record, the module searches for records with field inheritance relationships in the preceding process records. Field inheritance relationships are determined through field hierarchy information. If an extended field of a subsequent record contains a specification field, then the time sequence... The association module searches for records with the same specified fields in the preceding process records and uses them as a candidate preceding record set. Within the candidate set, three basic indicators are calculated for each record: the first is the time difference, calculated by subtracting the event time of the preceding record from the event time of the subsequent record; if the time difference is negative, the record is not included in the candidate set. The second is field consistency; the module compares the extended fields of the preceding and subsequent records item by item and calculates the percentage of identical fields, which is used as the field inheritance strength. The third is the source attribute difference; if the two records have the same source attribute, the difference is zero; otherwise, it is recorded as one. Establish an association scoring formula and sort the candidate set according to the principle that the smaller the time difference, the higher the field consistency, and the smaller the source attribute difference; select the highest-scoring predecessor record from the highest-ranked item as the unique predecessor record of the successor record, and write this correspondence into the predecessor number field of the process record sequence; the output of the time sequence association module is a process record sequence with a predecessor pointing attribute.

[0027] The resource load generation module calculates and breaks down the usage of a single process record into three basic quantities, and combines them through weighted recombination. Each record generates three incremental contributions. The three basic quantities are: record value, time difference from the same source, and preceding difference.

[0028] The numerical value is read directly from the numerical fields in the structured record; the time difference is obtained from the difference between the event time of the current record and the event time of its predecessor; the predecessor difference is calculated from the numerical difference between the same type of fields in the current record and its predecessor.

[0029] The mechanism by which the resource load generation module generates weight groups is as follows: If the proportion of time difference in a record is higher than the average level, the weight of the time component is increased; if the field consistency is high, the weight of the inherited component is increased; if the source attribute difference is zero, the weight of the source component remains stable; the sum of the three weights remains 1, and the weight changes dynamically with the characteristics of the current record; each record is processed in the order of records, the record value is multiplied by the first weight, the time difference is multiplied by the second weight, and the previous difference is multiplied by the third weight, and the sum of the three results is the incremental contribution of the current record; the resource load generation module accumulates the incremental contribution of each record to obtain the total usage of the process; when processing multi-process links, the resource load generation module writes the total usage of the previous process into the initial usage field of the current process, so that the usage forms a unidirectional transmission between process sequences.

[0030] The results output module receives the calculation results from the resource load generation module and combines the total usage, incremental composition, accumulation order, and forward propagation results of each process into a structured result set. The structured result set includes the process number, total usage of the process, usage composition data group, usage of the preceding process, and usage of the current process. The results output module writes the result set into an output file, which can be called by external management systems and can also be used for subsequent construction analysis.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
