Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of environmental protection and pollution control, and particularly to an intelligent management platform for the remediation of industrial organic contaminated soil based on digital twin. Background Art
[0002] Soil pollution, especially the remediation of industrial organic contaminated soil, is an important task in the current environmental governance field. With the acceleration of the industrialization process, the problem of soil pollution is becoming increasingly serious. In particular, organic pollutants in industries such as petrochemical, metallurgy, and agriculture have a huge impact on soil quality. Although traditional soil remediation methods can effectively remove some pollutants, they have problems such as low remediation efficiency, insufficient resource utilization, excessive pollutant emissions, and lack of real-time monitoring and management during the remediation process.
[0003] Currently, during the soil remediation process, although some enterprises have begun to use modern equipment for operation monitoring, there is a lack of an effective integrated management platform. The collection of construction site data mainly relies on manual operations and local sensors, lacking an intelligent and highly real-time scheduling and monitoring system, resulting in key factors such as construction progress, resource consumption, and environmental impact not being timely feedback and optimized. In addition, traditional methods for remediating contaminated soil mostly rely on manual judgment, lacking data-driven scientific decision-making, leading to low remediation effects and construction efficiency, and it is difficult to ensure safety and environmental protection.
[0004] Specifically, there are usually the following main defects in the current soil remediation construction monitoring:
[0005] (1) Incomplete and inaccurate real-time monitoring and data collection:
[0006] Current soil remediation projects mostly rely on traditional sensors and manual collection methods, with limited accuracy and coverage of data acquisition, unable to fully reflect the dynamic state of the construction site.
[0007] The complex geological environment and changing climate conditions at the construction site may cause sensor failures and even data anomalies, affecting the remediation effect and project progress.
[0008] (2) Inefficient construction resource scheduling and management:
[0009] Due to the lack of an intelligent resource scheduling system, the allocation of construction resources (such as personnel, machinery, earthwork, etc.) often relies on manual arrangements, resulting in problems of overuse or idle waste.
[0010] The monitoring of construction progress and equipment usage is lagging, and the construction plan cannot be adjusted in a timely manner, resulting in low efficiency.
[0011] (3) Lack of environmental protection monitoring and carbon emission optimization:
[0012] During the current repair process, the monitoring of environmental protection parameters such as pollutant emissions and energy consumption is insufficient, and the real-time monitoring and optimization of carbon emissions cannot be achieved, which easily leads to non-compliant emissions and resource waste.
[0013] During the repair process, the use of equipment and energy lacks precise optimization, resulting in unnecessary carbon emissions, affecting the environment and repair costs.
[0014] (4) Lack of equipment failure prediction and timely maintenance:
[0015] The operation status monitoring and maintenance management of key equipment such as thermal desorption equipment are insufficient, and there is a lack of intelligent failure prediction and early warning mechanisms, resulting in frequent equipment failures and affecting the repair progress and efficiency.

Description of the Drawings
[0035] Figure 1It is the system architecture diagram of the intelligent management platform for industrial organic contaminated soil remediation based on digital twin disclosed by the present invention.
[0036] Figure 2 It is the example data actually collected in the construction data acquisition module of the present invention. Detailed implementation manners
[0037] In order to enable those skilled in the art of the present technology to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and the best embodiments. Based on the embodiments of the invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the invention.
[0038] As shown in the figure, the present invention includes:
[0039] (1) Construction data acquisition module:
[0040] The construction data acquisition module is the basic part of the digital twin platform and undertakes the task of real-time acquisition of various key data at the construction site. First, this module makes precise sensor arrangements at the construction site, and the sensors should be reasonably configured according to different construction links. The deployment work includes selecting appropriate sensor types and deployment positions according to the complexity of the project, soil characteristics, and requirements of the construction area. After the deployment is completed, the sensors start to collect data in real time and transmit it to the platform through the data acquisition gateway. In order to ensure the accuracy and reliability of the data, the platform also sets up a data quality monitoring mechanism. By monitoring the quality of data acquisition in real time, abnormal values can be detected in a timely manner, and necessary correction measures can be taken. The platform can also generate real-time construction status reports based on the collected data.
[0041] Construction data includes construction progress data, mechanical equipment operation status, environmental monitoring data, soil pollution data, and construction safety data. The construction data acquisition module includes a temperature and humidity sensor, an earthwork volume sensor, a mechanical operation status monitor, an air pollutant concentration sensor, and a data acquisition gateway. The temperature and humidity sensor, earthwork volume sensor, mechanical operation status monitor, and air pollutant concentration sensor are used to acquire construction data, and each device is responsible for collecting different types of data. The earthwork volume sensor can monitor the progress of soil excavation and transportation in real time, while the pollution gas sensor is responsible for monitoring the concentration of harmful gases at the construction site to ensure compliance with environmental protection standards. In addition, the mechanical operation status monitor can provide real-time feedback on the operation status of construction machinery, helping management personnel to detect equipment failures or inefficient operations in a timely manner. The data acquisition gateway is used to receive the construction data, which includes real-time temperature and humidity, gas concentration, mechanical operation status, construction progress, and other information, providing comprehensive and timely data support for the construction site. To ensure the stability and security of data transmission, the data is transmitted to the cloud or local server through one or more wireless communication technologies such as Wi-Fi, 4G / 5G, or LoRaWAN, ensuring long-distance and high-frequency data transmission. Through this real-time data acquisition, the platform can continuously monitor various dynamics during the construction process, providing basic data for subsequent data processing and analysis.
[0042] To better illustrate the working principle of the construction data acquisition module, as Figure 2 shown, several example data actually collected are listed. These data cover key aspects of the soil remediation project, such as construction progress, mechanical equipment operation status, environmental monitoring, and soil pollution status.
[0043] (2) Data Processing and Analysis Module:
[0044] The main function of the data processing and analysis module in the digital twin platform is to perform real-time analysis on a large amount of raw data obtained from the construction data acquisition module, extract key information, and provide decision support. It includes data cleaning, data modeling, real-time analysis, and data visualization.
[0045] (1) Data Cleaning: It is the preprocessing of data collected from the site to remove incomplete, inaccurate, or redundant data, thereby ensuring the accuracy of subsequent analysis results. Since the data acquisition process at the construction site may be affected by factors such as environmental interference and equipment failures, the raw data may contain noise, missing values, or outliers, which may all affect the analysis results.
[0046] Specific implementation methods:
[0047] Missing value filling: Interpolation methods (such as linear interpolation) are used to fill in the missing values in the data. In time series data, if the temperature data at a certain moment is missing, it can be estimated by linear interpolation of the data before and after.
[0048] Outlier detection and removal: The Z-score method is used to detect outliers. Z-score is a standardized statistical method, and the formula is:
[0049]
[0050] where X is a certain data point, μ is the mean of the data set, and σ is the standard deviation. When Z > 3, it means that the data point is an outlier and can be removed.
[0051] (2) Data modeling: A data modeling system based on multivariate regression analysis includes three core prediction models: construction efficiency prediction model (SE-Model), equipment health prediction model (EH-Model), and pollutant emission prediction model (PE-Model).

[0087] 3) Cross-validation: Use k-fold method to verify the generalization ability of the model.
[0088] (3) Real-time analysis: The three core prediction models (SE-Model, EH-Model, PE-Model) generated through data modeling form a closed-loop control with the real-time analysis engine. The real-time analysis module corresponding to each model adopts an adaptive sliding window mechanism, and the window time parameter is dynamically adjusted according to the physical characteristics of the variables.

[0093] Real-time analysis steps:
[0094] 1) Window data normalization: Perform online Z-score standardization on {X1, X2, X3} within the window
[0095] Streaming standardization incremental calculation: mean = previous_mean + (x_new - previous_mean) / nstd = sqrt(((n - 1)*previous_std 2 + (x_new - mean) 2 ) / n)
[0096] 2) Efficiency dynamic prediction: Update the regression equation every 30 seconds: β0 + β1X1 + β2X2 2 + β3log(X3)
[0097] 3) Progress deviation warning: When the predicted value Y of 3 consecutive windows < 85% of the BIM planned value, trigger the following operations: Adjustment suggestions, automatically generate the equipment load optimization plan X1' = X1 × (Y_target / Y_current)^(1 / β1)

[0105] RMS value of the resonance band (800 - 1200Hz)
[0106] 2) Degradation trend prediction: Update Y = β0 + β1X4^(1 / 3) + β2exp(X5) on a minute-by-minute basis

[0116] The regularization parameter λ is automatically adjusted according to the signal-to-noise ratio of the data: λ = 0.1×log(‖X‖2)
[0117] 2) Exceedance response: Trigger when Y > 75 μg / m for 5 consecutive minutes 3 Trigger:

[0119] Material adjustment: Automatically reduce the proportion of muddy aggregate X9' = X9×(0.95)^k (k is the number of exceedance times)
[0120] (4) Data visualization: It is to display the results of data analysis in the form of graphs, charts or dashboards, so that construction managers can intuitively understand the data and make quick decisions based on it. Visualization can not only show the real-time progress of construction, but also help to discover potential bottlenecks and risks, and support intelligent decision-making.
[0121] Specific implementation methods:
[0122] (4-1) Dashboards and real-time charts: By constructing real-time dashboards, display key indicators during the construction process (such as construction progress, mechanical status, concentration of polluting gases, etc.). KPI (Key Performance Indicator) dashboards can be used to display this data. For example, a dashboard showing the progress of earth excavation can use a chart with a percentage progress bar, and indicate the current status through color changes (such as green for normal progress and red for lag).
[0123] (4-2) Scatter plots and line charts: Use scatter plots to show the relationship between equipment load and construction efficiency, or use line charts to show the changing trend of daily soil pollution concentration, to help project managers intuitively understand the key changes during construction.
[0124] (III) Construction intelligent supervision module:
[0125] The construction intelligent supervision module is one of the core modules of the digital twin platform, responsible for the intelligent scheduling and management of all resources at the construction site. It includes a personnel scheduling system, a machinery scheduling system, an earthwork scheduling system, and a safety management system, which are used to monitor the construction progress, personnel arrangements, the use of construction machinery and equipment, and earthwork transportation in real time based on the collection and analysis of construction data, to conduct intelligent scheduling and management of the resources at the construction site, optimize the allocation of various resources during the construction process, improve construction efficiency, reduce resource waste, and ensure construction quality and safety.
[0126] (1) Personnel scheduling system: It can reasonably allocate work tasks according to the actual situation of the construction site, ensure the efficient cooperation of personnel, and avoid resource idleness or duplicate work. Through RFID tag technology, the platform can track the working status and location of each worker in real time, automatically optimize task allocation, and ensure construction efficiency.
[0127] Obtaining key parameters:
[0128] 1) Real-time location data: UWB positioning system (accuracy ±15 cm, update frequency 1 Hz)
[0129] 2) Work type skill matrix: Industrial worker level (L1 - L5), high-altitude operation qualification, etc. (from the BIM database)
[0130] 3) Physiological state indicators: Smart safety helmets collect heart rate (bpm) and body temperature (°C) data
[0131] 4) Task topological relationship: Node weight w_i ∈ [1, 5] in the task dependency graph (G = (V, E))
[0132] Steps of the resource scheduling algorithm:
[0133] 1) Chromosome encoding: Adopt a three-dimensional gene structure:
[0134] · The first dimension: Personnel ID (RFID number)
[0135] · The second dimension: Task sequence (WBS number decomposed based on the BIM model)
[0136] · The third dimension: Time window constraint ([start time, end time])
[0137] 2) Calculation of the fitness function:
[0138] Multi-objective weighted evaluation
[0139] def fitness(chromosome):
[0140] efficiency = Σ(task standard working hours / actual allocated working hours) # Based on the historical working hours database
[0141] safety = 1 - Σ(overtime working hours) / total working hours # When the daily working hours > 10h, it is counted as overtime. skill_match = Σ(task required skill level - actual personnel level) 2 # Penalty for the deviation of industrial worker levels
[0142] return 0.6 * efficiency + 0.3 * safety + 0.1 * (1 / skill_match)
[0143] 3) Dynamic constraint handling:
[0144] Hard constraint: Gene repair is triggered when the detected heart rate of personnel > 120bpm
[0145] UPDATE chromosome SET task_assign = NULL
[0146] WHERE worker_id IN (SELECT id FROM workers WHERE heart_rate > 120)
[0147] Soft constraint: Skill mismatch is handled through a penalty function (weight coefficient λ = 0.05)
[0148] (2) Mechanical scheduling system: Real-time monitoring of all equipment at the construction site to ensure the reasonable scheduling of mechanical equipment and avoid equipment idleness or overuse. When a piece of machinery fails, the system can intelligently schedule backup equipment to ensure that the construction is not affected.
[0149] Obtaining key parameters:

[0151] 2) Task queue pressure: Quantity of transportation to be processed / rated transportation capacity of equipment (unit: trips / h)
[0152] 3) Energy consumption cost coefficient: Instantaneous fuel consumption of diesel engine (L / h) × real - time fuel price data
[0153] Steps of the resource scheduling algorithm:
[0154] 1) Gene coding optimization:
[0155] Adopt a double - layer coding structure:
[0156] Upper layer: Equipment - task assignment matrix (0 - 1 coding)
[0157] Lower layer: Task execution order (permutation coding)
[0158] 2) Multi-objective fitness function:
[0159] F = α * (1 / total fuel consumption) + β * equipment utilization rate + γ * Σ(RUL_i / RUL_initial)
[0160] where α = 0.5, β = 0.3, γ = 0.2
[0161] 3) Fault response mechanism:
[0162] When the EH-Model warns that RUL < 4h:
[0163] Dynamically adjust the equipment transport capacity coefficient: transport capacity' = transport capacity × (RUL / 8h)^2
[0164] Trigger the equipment replacement gene recombination operation
[0165] 4) Energy consumption-aware crossover operator:
[0166] When selecting the crossover point, preferentially retain the low fuel consumption task sequence segment
[0167] Introduce the fuel consumption gradient: Δc = |c_parent1 - c_parent2|
[0168] Technical features:
[0169] Transport capacity dynamic attenuation model: Q(t) = Q0 × e^(-kt), k = 0.05 / h (based on equipment wear data)
[0170] Oil circuit pressure compensation algorithm: Automatically correct the calculated transport capacity value when the oil pressure < 2.5MPa
[0171] (3) Earthwork scheduling system: Focus on the monitoring and scheduling of earthwork transportation. By real-time tracking of the construction progress, the system can dynamically adjust the earthwork transportation tasks to ensure that the excavation, transportation, and stacking of earthwork reach the best ratio, thereby avoiding excessive or insufficient earthwork transportation and reducing the risk of project delay or resource waste.
[0172] Obtaining key parameters:
[0173] 1) Real-time earthwork volume: The measurement accuracy of the 3D laser scanner is ±0.5m 3 , and the update period is 5min
[0174] 2) Transportation path topology: GIS-based slope-distance weight map (weight = fuel consumption × time)
[0175] 3) Stockpile capacity: The remaining capacity is monitored by an array of pressure sensors (unit: m 3 )
[0176] Steps of resource scheduling algorithm:
[0177] 1) Gene expression design:
[0178] Transport path gene: Use variable-length gene encoding for different combinations of transport routes
[0179] Loading capacity gene: Real number encoding (range: 3 - 15m 3 , step size 0.5m 3 )
[0180] 2) Dynamic fitness calculation:
[0181] def earth_fitness(individual):
[0182] transport_cost = Σ(path fuel consumption × real-time oil price)
[0183] time_penalty = max(0, actual progress - planned progress)^2
[0184] balance_score = 1 - |excavation volume - transportation volume| / total earthwork volume
[0185] return 0.7*(1 / transport_cost) + 0.2*balance_score + 0.1*(1 / time_penalty)
[0186] 3) Real-time correction mechanism:
[0187] When the excavation deviation detected by laser scanning > 10%:
