Description

TECHNICAL FIELD

[0001] The present application relates to the field of construction informationization and intelligent management and control technology, in particular to a construction management system and method based on multi-source data analysis. BACKGROUND

[0002] In the current digital-based construction management and supervision system, automated decision-making is highly dependent on data obtained from progress plans and various sensors. However, there is a fundamental design flaw in existing technology: the supervision system often equates the "completion" status label of a task with the "data existence" of a spatial location to the "safety premise met" for decision-making.

[0003] This flaw is manifested in both time and space dimensions: In the time dimension, the supervision system is like a warehouse manager who only acts on documents. When it receives a "concrete pouring completed" status report, it immediately authorizes the subsequent "tensioning prestressed steel beam" process to start, but never checks whether the actual strength of the concrete has reached the safe tensioning standard through age growth or maintenance. This leads to a "premature" decision in time, i.e., the physical world's dynamic conditions are not ready, but the supervision system has logically determined that the task chain can be pushed forward.

[0004] In the spatial dimension, the supervision system assumes that spatial information from the BIM component library and the on-site positioning supervision system is naturally consistent and reliable. If it sees from the drawings (BIM) that a construction machinery and equipment is located at point A, and receives feedback from the positioning beacon that the equipment is at point A, it believes that the spatial information is accurate, but it cannot detect that due to coordinate system calibration errors, the two "points A" may be misaligned by tens of centimeters in the physical world. This leads to a "misalignment" decision in space, i.e., the supervision system issues instructions based on an internally consistent but actually distorted world model.

[0005] In summary, the mechanism of the existing technology, which does not deeply verify the premise of decision-making, makes the decision-making foundation fragile and vulnerable in a dynamic and complex construction environment, easily leading to hidden and major quality and safety risks.

[0006] To solve the above problems, the present application proposes a construction management and supervision system and method based on multi-source data analysis. SUMMARY

[0028] The construction management system based on multi-source data analysis includes a task state monitoring module, a dynamic condition management module, a time logic verification module, a spatial coordinate acquisition module, a spatial consistency verification module, a safety event identification module and an execution result report generation module; The task state monitoring module is used for monitoring the state field update event of the construction project progress management database to capture the pre-path task completion signal, and parsing the instruction queue of the plan scheduling module to receive the subsequent path task starting instruction; the dynamic condition management module is used for extracting the pre-path task completion time from the construction project progress management database, and querying and extracting the dynamic condition type and threshold parameter of the subsequent path task from the task dependency rule library; the time logic verification module is used for executing corresponding time logic verification according to the dynamic condition type, judging whether the construction dynamic context is ready or not and outputting the Boolean result; the spatial coordinate acquisition module is used for extracting the design coordinates of the construction machinery from the BIM component library, obtaining the real-time measurement coordinates of the construction machinery from the positioning system data interface, and querying the tolerance parameter from the spatial tolerance rule library; the spatial consistency verification module is used for calculating the actual construction spatial deviation based on the design coordinates, the measurement coordinates and the tolerance parameter, executing the spatial logic verification and outputting the Boolean result; the safety event identification module is used for determining whether the subsequent path task state conversion is allowed according to the Boolean result of the time and space logic verification, and blocking the task state conversion and generating the task state conversion blocking record when it is not allowed; the execution result report generation module is used for generating the structured execution result report according to the execution result of the safety event identification module and sending it to the designated supervision system data receiving end.

[0029] The implementation process of the construction management system and method based on multi-source data analysis is described in detail by taking the "prestressed steel beam tensioning" process in a certain bridge engineering project as a subsequent path task. In this project, the pre-path task is "bridge main beam concrete pouring", and the start of the subsequent path task "prestressed steel beam tensioning" needs to meet strict time and space logic compliance requirements. The whole supervision process is completed by an automatic data analysis system deployed on the project server. The system includes a task state monitoring module, a dynamic condition management module, a time logic verification module, a spatial coordinate acquisition module, a spatial consistency verification module, a safety event identification module and an execution result report generation module, and each module cooperates to realize the whole process supervision.

[0030] After the supervision process is started, the task state monitoring module first continuously monitors the data table of the construction project progress management database. When the construction personnel confirms that the "bridge main beam concrete pouring" task is completed on the business terminal, the state field of the task in the database is updated, and the module immediately captures this state change signal. At the same time, the module parses the instruction queue from the project plan scheduling module, and extracts the starting instruction for the "prestressed steel beam tensioning" process from it. The instruction contains the unique identifier "ZL-2024-0512-001" of the subsequent path task, and the completion task signal capture and starting instruction receiving are completed.

[0031] Subsequently, the dynamic condition management module intervenes. The module extracts the database transaction timestamp when the task state of "bridge main girder concrete pouring" changes to completed from the construction project progress management database, determining the completion time as May 12, 2024, 14:30:00. Then, the module queries the preset task dependency rule library according to the subsequent path task unique identifier "ZL-2024-0512-001" - the library is a structured data table containing subsequent path task unique identifier, dynamic condition type, threshold parameter, etc. fields, and the dynamic condition type is preset as time delay type, physical index type, and approval state type. After querying, the dynamic condition type corresponding to the "prestressed steel strand tensioning" process is physical index type, and the module further extracts the threshold parameter "30MPa" from the corresponding record in the rule library, that is, the concrete strength needs to reach 30MPa before the subsequent process can be started.

[0032] The time logic verification module executes the corresponding verification logic according to the obtained dynamic condition type. Since the task dynamic condition is of the physical index type, the module obtains the real-time reading of the concrete strength related to the "prestressed steel strand tensioning" process through the designated Internet of Things sensor data interface. After data collection and transmission, the sensor feedbacks that the current concrete strength is 32MPa, and the module judges that the real-time reading is greater than the threshold parameter 30MPa, determining that the construction dynamic context is ready, and the time logic verification result output is true. If the dynamic condition type is time delay type or approval state type, the system will execute the corresponding verification logic: the time delay type will calculate the difference between the current system time and the completion time of the preceding task, and compare it with the threshold time length; the approval state type queries the construction project approval management system database to verify whether the approval state and the threshold string are completely matched.

[0033] At the same time of the synchronous advancement of the time logic verification, the spatial coordinate acquisition module starts to collect spatial related data. The module extracts the tensioning equipment design coordinates associated with the task from the preset BIM component library according to the subsequent path task unique identifier "ZL-2024-0512-001", denoted as BIM coordinates (X b =100.0m, Y b =200.0m, Z b =30.0m), which is a structured database storing the mapping relationship between task unique identifier and entity three-dimensional coordinates. Subsequently, the module obtains the real-time measurement coordinates of the same tensioning equipment through the positioning supervision system data interface deployed on the construction site - the interface provides spatial position data stream conforming to the predetermined communication protocol, denoted as positioning coordinates (X p =100.2m, Y p =200.1m, Z p= 30.0m). Then, the module queries the preset spatial tolerance rule base, which is also a structured data table, storing the mapping relationship between the construction project task unique identifier and the tolerance parameter, and finally obtains the spatial consistency tolerance parameter δ = 0.5m of the “prestressed steel tendon tensioning” process.

[0034] The spatial consistency verification module calculates the actual construction space deviation D based on the obtained BIM coordinates, positioning coordinates, and tolerance parameters through the three-dimensional Euclidean distance formula. Substituting the assumed data into the formula: D = √[(100.0-100.2)²+(200.0-200.1)²+(30.0-30.0)²]=√[(-0.2)²+(-0.1)²+0²]=√(0.04+0.01)=√0.05≈0.224m. The module compares the calculated actual construction space deviation D ≈ 0.224m with the tolerance parameter δ = 0.5m, and since 0.224m ≤ 0.5m, it is determined that the construction space cognition is consistent, and the spatial logic verification result is output as true.

[0035] The safety event identification module receives the time logic verification result and the spatial logic verification result, both of which are logical true values, and immediately sends a state update instruction to the project progress management database, modifying the state field of the “prestressed steel tendon tensioning” process from the preset “waiting state” to “startable state”. If either verification result is false, the system will generate and persist a task state transition block record, which includes the subsequent path task unique identifier, the verification failure type (time verification failure or space verification failure), and the timestamp triggering the block, ensuring that construction risks are traceable.

[0036] Finally, the execution result report generation module generates a structured execution result report based on the execution result of the safety event identification module. The report contains all key information such as the subsequent path task unique identifier “ZL-2024-0512-001”, the time logic verification determination result “true”, the spatial logic verification determination result “true”, the pre-path task completion time “2024-05-12 14:30:00”, the dynamic condition type “physical index type” and the threshold parameter “30MPa”, the BIM coordinates (100.0m, 200.0m, 30.0m), the positioning coordinates (100.2m, 200.1m, 30.0m), and the tolerance parameter “0.5m”. The module generates this report as a structured data file and sends it to the designated project management system data receiving end through the pre-defined transmission interface, completing the entire construction management and supervision process.

[0037] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics of the present application. The embodiments should therefore be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No reference signs in the claims should be considered as limiting the scope of the claims with respect to the figures of the patent document.
