The system includes: alignment at the construction site; a laser ranging unit equipped with a laser ranging sensor; an AR projection unit equipped with an optical perspective display to overlay standard construction data onto the surface of the construction object; a voice and AR guidance module in the perception and execution layer receiving guidance instructions from the processing and decision-making layer, outputting correction prompts via voice, and outputting AR visual annotations; the AR guidance module includes a voice prompt unit and a projection prompt unit; the voice prompt unit receives guidance instructions from the processing and decision-making layer, synthesizes and outputs voice broadcasts, prompting construction personnel on the deviation position, value, and correction operation; the projection prompt unit is connected to the AR projection unit in the AR smart glasses terminal module, and the projection prompt unit and AR projection unit are connected to overlay and display deviation annotations, standard contours, or virtual ruler AR visual information onto the surface of the construction object; a standard process model library is set up in the process guidance module in the processing and decision-making layer, which stores standard process models for decoration technology, including process sequence information, standard construction parameters, and deviation judgment rules; the process sequence information includes the construction steps of the decoration technology, and the standard construction parameters include flatness. Gap width ,spacing and coating thickness The deviation judgment rules include the allowable deviation thresholds for construction parameters and the corresponding correction methods. The deviation identification module in the processing and decision-making layer has a built-in deviation detection model. The deviation detection model receives real-time construction data collected by the perception and execution layers. After inputting into the deviation detection model, it outputs the quantitative deviation value between the current construction parameters and the standard construction parameters, and determines whether the deviation exceeds the allowable threshold. The deviation detection model includes a feature extraction unit, a comparison calculation unit, and a threshold determination unit. The feature extraction unit extracts the geometric features of the construction surface from the acquired images and point cloud data. The geometric features include flatness.

The traceability report generation unit generates a construction quality traceability report based on the query instructions of the project manager. The recording and traceability module includes a rectification closed-loop management unit, which automatically generates rectification tasks after the deviation identification module determines that the deviation exceeds the standard, and pushes the rectification requirements to the construction personnel through the AR smart glasses terminal module. After the rectification is completed, the system re-collects construction data and verifies the rectification results until the deviation meets the standard. After that, the closed-loop information is recorded and uploaded to the blockchain. like Figure 1 , Figure 2 and Figure 3 As shown, taking the application of latex paint in interior decoration as an example, this paper specifically illustrates the application of this system in the actual construction process. Construction workers wear AR smart glasses from the AR smart glasses terminal module to guide and correct deviations during putty layer application. The system executes the following steps: Step 1: The construction worker starts the system and selects "Putty Application" as the current process. The process guidance module in the processing and decision-making layer loads the standard process model corresponding to latex paint application from the standard process model library. This model includes standard construction parameters for putty application, such as standard coating thickness values. The permissible deviation threshold for flatness is Through the AR projection unit in the perception and execution layer, the thickness of the putty application is marked as 2mm and superimposed on the surface of the wall in AR visualization. At the same time, the voice prompt unit in the voice and AR guidance module issues a voice reminder: "The thickness of the putty application should be controlled at 2mm and applied evenly." Step Two: During the application of putty by the construction workers, the laser ranging unit and visual recognition unit in the AR smart glasses terminal module collect real-time data on the wall's flatness. The deviation recognition module in the processing and decision-making layer receives the aforementioned real-time construction data and obtains the actual flatness parameters through the feature extraction unit. And the flatness deviation value is calculated by comparing the calculation unit: Among them Standard flatness parameters, when the threshold determination unit detects a certain area Exceeding the allowable deviation threshold, such as locally. If the deviation exceeds 3mm, the system determines that the deviation is excessive. At this time, the projection prompt unit in the voice and AR guidance module works in conjunction with the AR projection unit to mark the deviation location in the AR image of the wall with a red highlighted area. At the same time, the voice prompt unit issues a voice reminder: "The flatness deviation here exceeds the standard, and the deviation value is..." "It needs to be re-polished"; Step 3: Construction workers, based on AR visual annotations and voice prompts, smooth and correct the deviation areas. After correction, the system re-collects the flatness data of the area through the AR smart glasses terminal module and compares it again through the deviation recognition module. If the recalculated flatness data is correct... Once the deviation falls back to the allowable threshold range, the system determines that the rectification is qualified, and the rectification closed-loop management unit in the recording and traceability module of the management and recording layer records the deviation discovery, rectification operation and verification results as closed-loop information. Step 4: The construction personnel identity information, construction time, putty thickness parameters, flatness test results, deviation identification results and rectification operation records collected during the above construction process are uploaded to the blockchain node by the data on-chain unit to form an immutable construction record. The system then automatically loads the next process, such as the standard model for latex paint surface layer construction, and continues to guide the construction. Step 5: The project manager can query the quality traceability report of this latex paint construction through the management platform, extract relevant construction records from the blockchain, and generate a traceable quality report containing deviation analysis, rectification closure proof and responsibility information for construction acceptance or quality review.

[0024] Working principle: The system's usage process is as follows: Construction workers wear AR smart glasses from the AR smart glasses terminal module. The system loads the standard process model for the current process and overlays the standard construction parameters onto the surface of the construction object through the AR projection unit. The AR smart glasses collect construction data in real time and identify the deviation between the current construction parameters and the standard parameters through the deviation recognition module. If the deviation exceeds the allowable threshold, the system outputs correction prompts through voice and AR guidance modules and marks the deviation location and correction direction in the AR image. After the construction workers complete the rectification according to the guidance, the system re-collects data and verifies the rectification results, forming a closed-loop record. The construction record, deviation data, rectification results, and responsibility information are uploaded to the blockchain to generate a traceable quality report for the management platform to access.
