Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of construction big data processing, and in particular relates to a method, system, equipment and storable medium for predicting and managing protection of building material stacking areas. Background Art
[0002] As a lightweight, porous building material, autoclaved aerated wall insulation offers advantages such as thermal insulation, heat insulation, noise isolation, lightweight, earthquake resistance, fire resistance, easy construction, and environmental friendliness. However, its disadvantages are also significant. Due to its porous structure, it is highly absorbent and requires moisture-proofing during storage and transportation. At the same time, it is also important to note that high temperatures and exposure to sunlight can easily cause the already limited moisture in the building materials to escape, causing damage to the building materials. These disadvantages are common in many building materials. Therefore, how to monitor relative humidity, temperature, and light intensity in real time based on meteorological changes and the on-site environment, combine regional macroclimatic parameters with microclimatic parameters measured at the construction site, and integrate them into the BIM system to provide early warnings and coordinate construction processes, thereby improving the protection and prediction capabilities of building materials has become a key technical challenge in ensuring construction quality. Existing technologies often use single-sensor monitoring or static grading strategies, lacking dynamic prediction capabilities and failing to fully consider seasonal climate impacts, which can easily lead to misjudgments or control failures. From the perspective of transportation costs and transportation loss risks, the sales of construction materials have certain geographical restrictions, and the construction areas of regional construction units are generally also regional. This provides a feasibility basis for using historical meteorological data of specific construction areas to conduct building material protection forecasting and management. Summary of the Invention

It can also give corresponding control instructions according to the relative humidity, temperature and light intensity status to prevent moisture and water loss due to exposure to the sun, thereby improving the protection level of building materials on the construction site and reducing the loss rate.

If the error or drift exceeds the threshold, the fine-tuning mechanism is triggered, and only the weight calculation logic or variance penalty coefficient of the fusion layer is updated to keep the model adaptable to field changes. At the same time, the feedback evaluation module records the fine-tuning process and generates periodic operation evaluation reports for manual review.

The single-chip microcomputer controller is electrically connected to the temperature sensor, the humidity sensor and the light sensor in turn. Specifically, it is arranged on a shell, and the shell is fixed on a base to form a sensor assembly that is easy to move. When deploying, care should be taken not to allow the internal sensor group to be covered by the piles of building materials in the stacking area, and it should be placed as much as possible in the center of the stacking area. The peripheral sensor group should be placed at the south edge of the stacking area of building materials, and should not be covered by the piles of building materials in the stacking area.
[0029] like Figure 2 As shown, in step S3, the multi-model collaboration mechanism includes the following steps: S301. At the beginning of the earthwork excavation phase of the construction project, collect historical meteorological data of the hourly weather forecast and the corresponding measured meteorological data of the building material stacking area at the previous moment to form a model training data set; S302: Based on the collected model training data set, the Autoformer model, LSTM model and XGBoost model are trained independently, and the input is a multi-dimensional sequence input feature. , the output is the relative humidity forecast value for the next hour , temperature prediction value and light intensity prediction , complete the pre-training of the Autoformer model, LSTM model and XGBoost model; S303: Deploy the pre-trained Autoformer model, LSTM model, and XGBoost model independently, and input multi-dimensional sequence input features. , and obtain three independent sets of prediction values ( 、 、 ), ( 、 、 )and( 、 、 ), corresponding to relative humidity, temperature and light intensity respectively; S304: Forward pass the three independent pre-trained Autoformer models, LSTM models, and XGBoost models once respectively, and start Monte Carlo Dropout to make multiple predictions during inference, so as to obtain K different prediction results for each prediction item, and obtain three prediction sets. 、 and , , based on the prediction set 、 and , respectively calculate the corresponding model prediction mean 、 and and the corresponding variance 、 and , , , , , , ; S305.

[0031] Table 1 Model comparison and adaptation analysis table
[0032] In step S302, since XGBoost is an ensemble learning model based on gradient boosted trees (GBDT) rather than a neural network and does not support Dropout, Bootstrap resampling (a bagging-like mechanism) is used instead to achieve the "multiple sub-model sampling" effect. XGBoost's Bootstrap resampling alternative operation is specifically as follows: repeatedly sampling subsets of the input data, calling XGBoost prediction on each subset separately, and obtaining a set of prediction samples. If it is a single test sample (not a batch), the input cannot be resampled, and multiple weak models are used (multiple XGBoost models are trained with different random seeds), or a certain degree of uncertainty is introduced by setting different ntree_limit, colsample_bytree, and subsample.
[0033] like Figure 3As shown, in step S4, in order to effectively resist the impact of meteorological seasonal changes on the humidity prediction accuracy, improve the adaptability and stability of humidity prediction in different months and different climatic conditions, and realize a prediction correction mechanism with climate anomaly perception capability, climate anomaly analysis includes the following steps: S401, historical meteorological data acquisition and database construction phase, that is, to obtain the hourly meteorological observation historical data of the area where the building material stacking area is located in the past two years, including at least the temperature, relative humidity and light intensity at each hour, to form a historical meteorological database ; S402, the monthly grouping and statistical feature extraction stage, that is, statistically analyzing the quantile intervals of humidity, temperature, and light intensity by month, determining the historical normal ranges of humidity, temperature, and light intensity, and correcting the relative humidity prediction value, temperature prediction value, and light intensity prediction value based on the current month, and calculating the average humidity data for each month. , standard deviation , minimum value , maximum value , P10 quantile , P50 quantile , P75 quantile , P90 quantile ; S403, the climate anomaly model construction phase, that is, based on the quantile statistics results, determine the historical normal range of humidity, temperature and light intensity for each month [ , ]、[ , ][ , ], building a climate anomaly model for each month 、 and ; S404, climate anomaly correction factor calculation and prediction result correction stage, that is, according to the current month m, the corresponding climate anomaly model is extracted 、 and , the relative humidity prediction value output by the multi-model synergy mechanism , temperature prediction value and light intensity prediction , respectively make climate anomaly corrections: , , , in, is the relative humidity climate anomaly correction factor.

[0034] In step S402, the pth quantile It refers to the value at the pth percentile position after a set of sample data is sorted from small to large. P10 (10th percentile) is the number at the 10th percentile position from small to large, P50 (median, 50%) is the number in the middle, P75 (75th percentile position) is the number in the upper quartile, and P90 (90th percentile position) is the number close to the maximum value. Linear interpolation is used to calculate the quantile, which is the position of the pth quantile: , Where p is the quantile percentage, N is the number of historical humidity observations, and k is the theoretical index position; If k is an integer, then , if k is not an integer (assuming k=i+f, where i is the integer part and f is the fractional part), then ,in Represents historical humidity observation data for a certain month After sorting A value in .
[0035] like Figure 4 As shown, in step S5, a multi-level response control strategy is used to dynamically divide risk levels based on the humidity prediction value, temperature prediction value, light intensity prediction value, climate anomaly correction result, and on-site environmental conditions, and generate corresponding control instructions to implement protective management of the building material stacking area. Specifically, the strategy includes the following steps: S501.
