Abstract
Description
Technical Field
[0001] The present invention relates to the field of cold chain cargo status monitoring, and in particular to a multi-modal AIGC cold chain cargo status monitoring method and system. Background Art
[0002] With the development of the global economy and the diversification of consumer demand, cold chain logistics has become an important link in ensuring the quality and safety of high-value goods such as fresh food, medicines, and chemicals. The core of cold chain logistics is to ensure that the goods can always be in a temperature and humidity environment that meets the requirements during the entire transportation and storage process to prevent the goods from deteriorating, being damaged or failing due to temperature control failure or environmental changes. However, traditional cold chain monitoring systems face many challenges in practical applications, such as single monitoring methods, low frequency of data collection, frequent manual intervention and errors, and difficulty in achieving full-process dynamic monitoring.
[0003] At present, the cold chain logistics monitoring system mainly relies on temperature and humidity sensors for single environmental data collection. Such traditional sensors can usually only provide limited temperature and humidity information and cannot fully reflect the changes in the complex transportation environment. For example, changes in temperature and humidity are affected by a variety of factors such as the location of the goods, the driving status of the freight vehicles, and external weather changes. It is difficult to fully evaluate the status of the goods only by relying on temperature and humidity data. In addition, traditional monitoring methods often rely on manual inspections and regular inspections, which are prone to omissions or delays and cannot reflect the actual status of the goods in real time and accurately.
[0004] With the development of multimodal AIGC (AI-Generated Content), AIGC refers to artificial intelligence technology that can generate content in various media forms. It is an important development direction in the field of artificial intelligence in recent years. Multimodal data refers to information from multiple aspects such as environment, cargo status, and transportation equipment collected by different types of sensors and monitoring equipment. For example, temperature sensors, humidity sensors, CO2 concentration sensors, airflow sensors, and video surveillance cameras work together to obtain more comprehensive and accurate environmental information through data fusion. By combining these multimodal data with advanced artificial intelligence algorithms, the system can monitor and intelligently analyze the status of the cargo in real time, thereby achieving early warning of potential risks. Therefore, the cold chain cargo monitoring method based on multimodal data fusion has gradually become an important trend to improve the intelligence level of the cold chain monitoring system. Summary of the invention
[0005] In order to solve the above technical problems, the present invention proposes a multimodal AIGC cold chain cargo status monitoring method and system to solve at least one of the above technical problems.
[0006] To achieve the above object, the present invention provides a multi-modal AIGC cold chain cargo status monitoring method, comprising the following steps: Step S1: Acquire a real-time infrared monitoring image of cold chain goods; perform target visual recognition on the real-time infrared monitoring image of cold chain goods, perform temperature distribution fitting on the goods in the area, and construct a temperature distribution map of the goods in the area; Step S2: Obtain a full-range conventional monitoring image in the cold chain cargo transport warehouse; perform a three-dimensional layout distribution analysis in the warehouse on the full-range conventional monitoring image according to the cargo temperature distribution map in the area, and perform dynamic temperature distribution rendering to obtain a dynamic temperature distribution twin model; Step S3: Calculate the temperature fluctuation amplitude and predict the temperature change trend at multiple time points for the dynamic temperature distribution twin model, thereby generating a multi-time point temperature change trend prediction map for each sub-region; Step S4: mining abnormal temperature fluctuations on the multi-time point temperature change trend prediction map of each sub-region, and tracing the abnormal region to obtain the abnormal temperature change cargo node; Step S5: Analyze the surface texture details based on the abnormal temperature change cargo node, and then perform packaging damage detection to generate abnormal temperature change cargo damage detection results; Step S6: Make abnormal temperature emergency decisions and dynamic transportation route planning based on the abnormal temperature change cargo damage detection results, and build an intelligent cargo status decision model.
[0007] The present invention obtains real-time infrared monitoring images of cold chain goods and performs target visual recognition to accurately identify goods and obtain real-time temperature data. Constructing a temperature distribution map of goods in the area helps to understand the temperature distribution of goods and discover temperature anomalies or hot spots in advance, thereby ensuring the safety of cold chain transportation of goods. Dynamic temperature distribution rendering is combined with three-dimensional layout distribution analysis in the warehouse to generate a dynamic temperature distribution twin model, providing all-round temperature monitoring and analysis. Through the dynamic temperature distribution twin model, real-time monitoring and prediction of temperature changes of goods in the warehouse are achieved, which helps to ensure the quality of goods. Multi-time point temperature change trend prediction helps to predict the changing trend of cargo temperature and make timely adjustments and response measures. Generating a multi-time point temperature change trend prediction map for each sub-area helps to discover temperature anomalies or hot spots in advance. Abnormal temperature conditions are detected to ensure that the goods are within a safe temperature range. Abnormal temperature fluctuation mining and abnormal area tracing help to accurately locate the cause and scope of abnormal temperature conditions. By generating abnormal temperature change cargo nodes, timely measures are taken to deal with abnormal conditions and ensure the quality of goods. The combination of surface texture detail analysis and package damage detection helps to identify whether the goods are damaged due to abnormal temperature. The abnormal temperature change cargo damage detection results are generated to provide a comprehensive assessment of the cargo status and provide a basis for subsequent processing. Abnormal temperature emergency decision-making and dynamic transportation route planning based on the abnormal temperature change cargo damage detection results help to deal with abnormal conditions in a timely manner and ensure the safety of goods. The construction of an intelligent cargo status decision-making model improves decision-making efficiency and accuracy, and provides intelligent management and guarantee for cold chain cargo transportation.

[0009] The present invention obtains real-time infrared monitoring images of cold chain goods through infrared imaging monitoring, realizes non-contact monitoring of the temperature of goods, and captures the temperature information of goods in time. This helps to realize temperature monitoring of goods in a cold chain environment and improves the real-time monitoring capability of the state of goods during transportation. Through target visual identification and marking of each cargo node, the location and quantity of the goods are accurately identified, providing basic data for subsequent analysis and processing. This helps to distinguish and track the goods individually and improve the accuracy and reliability of the monitoring system. Accurate boundary positioning in the region is performed to generate the regional location coordinates of each cargo node, which helps to accurately grasp the location and range of each cargo. The regional location coordinates of the cargo nodes are generated to help establish the spatial distribution information of the cargo and provide basic data for subsequent temperature distribution fitting. The temperature gradient distribution characteristics of the image are obtained by temperature gradient distribution detection, revealing the temperature changes in different regions, and providing a basis for subsequent temperature distribution analysis. This helps to understand the temperature change law more carefully and provide more reliable data support for the accurate fitting of the temperature distribution of the cargo. According to the temperature gradient distribution characteristics, the regional location coordinates of each cargo node are fitted with the temperature distribution of the cargo in the region, and a temperature distribution map of the cargo in the region is constructed to more accurately understand the temperature distribution of the cargo. By constructing a temperature distribution map of the cargo in the area, a visual display of the temperature distribution of the cargo can be achieved, providing a basis for further temperature control and management.

[0011] The present invention acquires omnidirectional conventional monitoring images and reconstructs the global details of the images to improve the clarity and detail expression of the monitoring images, making the monitoring process more accurate and reliable. Constructing detailed reconstructed monitoring images helps to present the detailed information of the goods and the environment more clearly, and improves the monitoring system's ability to understand and analyze the status of cold chain goods. By segmenting the boundaries of the goods images one by one, the boundary image frames of multiple goods are obtained, and the position and boundaries of each goods are accurately determined, providing accurate data support for subsequent analysis and processing, which helps to segment and identify the goods individually, laying the foundation for subsequent morphological structure analysis and layout distribution analysis. The three-dimensional morphological structure characteristics of each cargo are generated through three-dimensional morphological structure analysis, which more comprehensively describes the morphological characteristics of the goods and provides more information for the comprehensive evaluation of the goods status. The three-dimensional morphological structure characteristic analysis helps to understand the changes in the morphological characteristics of the goods, and provides a more in-depth reference basis for subsequent transportation and management decisions. The internal three-dimensional layout distribution analysis obtains the three-dimensional layout distribution data of the goods, reveals the spatial distribution of the goods in the warehouse, and provides a reference for cargo management and transportation. This helps to better understand the spatial layout of the goods and provide optimization solutions and decision support for the transportation and storage of cold chain goods. A three-dimensional cargo distribution model is constructed through three-dimensional point cloud modeling of the transport warehouse to achieve modeling and visualization of the goods in three-dimensional space, providing a convenient tool for the spatial management of goods in the transport warehouse. The three-dimensional cargo distribution model helps to intuitively display the spatial layout of the goods and provide a more intuitive and comprehensive information display for the cold chain cargo status monitoring system. The dynamic temperature distribution twin model is obtained through dynamic temperature distribution rendering, which combines the temperature distribution of the goods with their three-dimensional morphological structure to achieve a comprehensive display and analysis of the cargo status. The dynamic temperature distribution twin model helps to fully understand the temperature distribution of the goods and provides a deeper perspective for the dynamic monitoring and analysis of the cold chain cargo status.

[0013] The present invention analyzes the light propagation in the transport warehouse through ray tracing processing, helps understand the distribution and path of light in the warehouse, and provides data support for subsequent light distribution identification. Through light distribution identification, the light distribution in the transport warehouse can be understood, which helps to evaluate the lighting conditions and light brightness distribution in the warehouse, and provides a basis for subsequent local dimming detection. Through dimming detection, the local dimming areas in the image are identified to help find potential areas with insufficient light or abnormal cargo conditions. Adaptive brightness enhancement processing improves the visibility of local dimming areas in the image, making the monitoring image clearer and easier to analyze, which helps to accurately monitor the status of the cargo. Through computer vision to detect the contour of the cargo, the contour information of each cargo is accurately extracted, providing accurate data support for subsequent detail sharpening and global detail reconstruction. Edge detail sharpening highlights the contour features of each cargo, enhances the clarity of the cargo edge in the image, and helps to more accurately analyze the shape and status of the cargo. Through global detail reconstruction of the image, the detailed features and overall visual effects of the cargo are comprehensively considered, the quality and analyzability of the monitoring image are improved, and a more accurate data basis is provided for cold chain cargo status monitoring.
[0014] Preferably, step S3 specifically comprises the following steps: Step S31: performing sub-region spatial division on the dynamic temperature distribution twin model, thereby obtaining a plurality of dynamic temperature sub-regions; Step S32: analyzing the time series variation of the temperature distribution of multiple dynamic temperature sub-regions to obtain the time series variation characteristics of the temperature distribution of each sub-region; Step S33: calculating the temperature change fluctuation amplitude of each sub-region temperature distribution time series change characteristic to generate the temperature change fluctuation amplitude characteristic of each sub-region; Step S34: Evolving the temperature change trend based on the temperature change fluctuation amplitude characteristics, and constructing a temperature change trend evolution curve for each sub-region; Step S35: Perform multi-time point temperature change situation prediction on the temperature change trend evolution curve of each sub-region, so as to generate a multi-time point temperature change situation prediction map of each sub-region. The present invention analyzes the temperature changes in the cold chain environment in more detail through sub-region spatial division, and subdivides the temperature distribution into multiple sub-regions, which is helpful for fine monitoring of the temperature status of different regions. The time-series change analysis of the temperature distribution reveals the temperature change trend of each sub-region, helps to understand the periodic and trend changes of temperature, and provides a basis for the subsequent calculation of the temperature change fluctuation amplitude. The temperature change fluctuation amplitude calculation quantifies the range of temperature changes in the sub-region, helps to evaluate the intensity of temperature fluctuations, and provides a quantitative reference for the subsequent evolution of temperature change trends. The temperature change trend evolution curve reflects the overall trend of temperature changes in the sub-region, helps to understand the long-term evolution law of temperature, and helps to predict future temperature change trends. The multi-time point temperature change situation prediction provides speculation on the temperature status of the sub-region at different time points, helps to monitor and predict the temperature status changes of goods in different time periods, and provides more dimensional information support for cold chain goods status monitoring.

[0018] The present invention extracts the abnormal cargo boundary image frame based on the abnormal temperature change cargo node positioning, accurately determines the position and range of the abnormal cargo, and provides key information for subsequent analysis and processing. The extraction of the abnormal cargo boundary image frame is helpful to realize the individual positioning and analysis of the abnormal cargo, and provides a data basis for the subsequent surface texture detail analysis. The surface texture detail analysis is performed on the abnormal cargo boundary image frame to generate the surface texture details of the abnormal temperature change cargo, and more comprehensively describe the surface characteristics of the abnormal cargo. The surface texture detail analysis is helpful to deeply understand the surface conditions of the abnormal cargo, and provides an important reference basis for subsequent packaging damage detection and analysis. The packaging damage detection is performed on the surface texture details of the abnormal temperature change cargo, and the abnormal temperature change cargo damage detection results are generated, and the damage of the cargo packaging is discovered in time. The packaging damage detection is helpful to discover the problems of cargo packaging in advance, ensure the integrity and safety of the cargo in transportation, and provide an important basis for the processing and management of abnormal cargo.

[0020] In the present invention, when the abnormal temperature change cargo damage detection result is that the packaging is not damaged, abnormal cargo temperature status data is generated, which is helpful to identify the abnormal temperature of the cargo and take countermeasures in time. The generated abnormal cargo temperature status data provides data support for subsequent abnormal temperature visualization and decision-making, improves the perception and processing efficiency of the abnormal cargo status, and visualizes the abnormal temperature of the dynamic temperature distribution twin model based on the abnormal cargo temperature status data to generate an abnormal temperature visualization model, which is helpful to intuitively display the abnormal temperature distribution. The abnormal temperature visualization model helps users to understand the abnormal temperature distribution more intuitively, and provides visualization support for abnormal temperature emergency decision-making. Abnormal temperature emergency decision-making is made according to the abnormal temperature visualization model, and an abnormal temperature emergency strategy is constructed, which can quickly make emergency treatment when abnormal temperature is found. The construction of abnormal temperature emergency strategy is helpful to deal with potential temperature problems in advance, ensure the quality and safety of goods, and improve the processing efficiency of abnormal situations. When the damage detection result is damaged packaging, a cargo packaging damage signal is generated, which helps to quickly discover the problem of cargo packaging and take timely measures to avoid further damage to the cargo. The generated cargo packaging damage signal provides important information for subsequent dynamic transportation path planning to ensure the safety of the cargo during transportation. Dynamic transportation path planning is carried out based on the cargo packaging damage signal, and a packaging damage planning path is generated, which can avoid potential dangerous areas and ensure the integrity of the cargo during transportation.

[0028] In the embodiment of the present invention, refer to Figure 1 , is a schematic flow chart of the steps of a multi-modal AIGC cold chain cargo status monitoring method of the present invention. In this example, the steps of the method include: Step S1: Acquire a real-time infrared monitoring image of cold chain goods; perform target visual recognition on the real-time infrared monitoring image of cold chain goods, perform temperature distribution fitting on the goods in the area, and construct a temperature distribution map of the goods in the area; In this embodiment, a suitable infrared camera is selected to ensure that it has high resolution and sufficient field of view to fully cover the cold chain cargo area. An infrared camera is installed in the cold chain transport warehouse to ensure that the camera position can effectively capture the temperature information of the cargo. The camera angle is adjusted to avoid reflection and occlusion. The parameters of the infrared camera, such as frame rate, sensitivity and temperature range, are configured to ensure that the temperature changes of the cargo can be accurately captured. An automatic acquisition program is set to regularly acquire real-time infrared monitoring images, and the image data is transmitted to the central processing unit for subsequent analysis. The acquired infrared images are denoised by using methods such as Gaussian filtering or median filtering to reduce noise interference in the image. Contrast enhancement and histogram equalization techniques are applied to improve the clarity and contrast of the infrared image to facilitate subsequent target recognition. A suitable target recognition algorithm is selected, such as YOLO (You Only Look Once) or Faster R-CNN, select the appropriate model for cargo identification according to specific needs, use the selected target recognition algorithm to analyze the processed infrared image, identify various types of cargo in the area, record the bounding box, category and temperature information of each target, verify the accuracy of the recognition result, and ensure that the identified cargo is consistent with the actual situation. If the recognition accuracy is not high, consider adjusting the algorithm parameters or using a more complex model, extract the temperature value of each cargo from the recognition result, and record the location coordinates and temperature information of each target, select a suitable temperature distribution fitting method, such as interpolation (such as Kriging interpolation or bilinear interpolation) or regression analysis method, and construct a temperature distribution map of the cargo in the area based on the extracted temperature data. Use the selected algorithm to spatially fit the temperature to generate a temperature distribution model, visualize the fitted temperature distribution data, and use heat maps or three-dimensional graphics to display the temperature distribution in the area for easy analysis and monitoring.
[0029] Step S2: Obtain a full-range conventional monitoring image in the cold chain cargo transport warehouse; perform a three-dimensional layout distribution analysis in the warehouse on the full-range conventional monitoring image according to the cargo temperature distribution map in the area, and perform dynamic temperature distribution rendering to obtain a dynamic temperature distribution twin model; In this embodiment, a high-resolution surveillance camera is selected to ensure good low-light performance to adapt to the lighting conditions in the warehouse. The installation position and angle of the surveillance camera are designed according to the layout of the cold chain goods to ensure that every corner of the entire transportation warehouse is covered to avoid blind spots. The monitoring system is configured to set a timed shooting or continuous recording mode to ensure that a full range of conventional surveillance images can be obtained in real time. The acquired surveillance images are stored in a database or cloud storage in real time to ensure data security and accessibility. The acquired conventional surveillance images are preprocessed, including denoising, contrast enhancement and color correction to improve image quality. Appropriate image processing and analysis tools are selected, such as OpenCV, MATLAB or deep learning frameworks (such as TensorFlow, PyTorch), and computer vision technology is used to perform target detection on the surveillance images to identify the location and distribution of various types of goods in the warehouse. Based on the recognition results, a three-dimensional spatial layout model of the goods in the warehouse is constructed, the relative position and layout relationship of each goods are recorded, the temperature data of each goods is extracted from the previously generated temperature distribution map of the goods in the area, and it is combined with the spatial layout data of the goods in the warehouse. Suitable three-dimensional rendering tools are selected, such as Blender, Unity or a custom rendering engine, to realize the visualization of dynamic temperature distribution.
