Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of traceability management, and in particular to a blockchain-based traceability management system and method for velvet materials. BACKGROUND

[0002] In the traditional management system of velvet materials, there are many problems in the data recording and management of materials at various links from production, storage to logistics transportation. The previous data management method relies on a centralized database, and the data is vulnerable to human tampering, malicious attacks or system failures, which makes it difficult to ensure the accuracy and integrity of the data. This makes it impossible to provide reliable data for all parties involved in the entire life cycle of the velvet material, thereby affecting the evaluation of the material quality, the monitoring of the transportation process and the subsequent production and use. For example, if the production data is tampered with, it may lead to a misjudgment of the material performance in the subsequent production process. In the logistics transportation process, if the transportation data is inaccurate, it is difficult to accurately assess the damage that the material may suffer during transportation.

[0003] Velvet materials have unique physical and chemical properties, and their quality is easily affected by many factors. During transportation, the physical properties of the material such as tensile strength, elasticity and bulk density will change, and environmental factors such as light, temperature and humidity, vibration, etc. will also cause different degrees of damage to the material, such as petal deformation, light fading, etc. However, traditional transportation loss assessment methods often only consider a few factors, lacking comprehensiveness and accuracy. For example, they may only focus on physical damage during transportation, while ignoring the long-term effects of light and humidity on the color and performance of the material. This limitation makes it impossible to accurately assess the actual loss of the material during transportation, and thus it is difficult to choose the optimal transportation path, increasing the risk of transportation costs and material loss.

[0052] In the embodiment, the velvet flower material petal deformation influence analysis in step S2 includes the following specific steps:

[0058] Step S3: Conduct material transportation anomaly analysis based on the transportation and lighting conditions during the logistics process of velvet flower products;

[0059] In this embodiment, the material transportation anomaly analysis in step S3 includes the following specific contents:

[0060] S31. Obtain the travel time, road surface condition, temperature, humidity, light intensity, and shading status of the corresponding road surface location for each route. The temperature, humidity, and light intensity at each time point are obtained from the corresponding weather forecast. Obtaining these information from the weather forecast is standard practice and will not be elaborated upon. The temperature anomaly is obtained by integrating the standard deviation of the temperature at each time point along the route and the suitable temperature range for the corresponding velvet material over the route time, then dividing by the standard duration. The humidity at each time point along the route and the standard deviation of the suitable humidity range for the corresponding velvet material over the route time... The humidity anomaly is obtained by integrating the time interval and dividing by the standard duration. It should be noted that the standard duration is only used to eliminate time units. The influence of temperature and humidity on the material color is obtained by weighted summation of temperature and humidity anomalies. The influence of temperature and humidity on the material color is quantified by calculating temperature and humidity anomalies and performing weighted summation. The color stability of velvet material is closely related to temperature and humidity. Different temperature and humidity conditions may cause chemical reactions in the pigment molecules in the material, thus affecting the color of the material. By calculating the integral of the standard deviation of temperature and humidity from the suitable range, the cumulative effect of temperature and humidity deviating from the suitable range during the entire transportation process can be reflected, which is in line with the basic principle of material being affected by the environment.

[0061] S32. Obtain the light intensity at each point on the corresponding route at the corresponding time and the shading effect of the covering on the light. Subtract the shading light intensity from the light intensity to obtain the direct light intensity at the corresponding point. Divide the direct light intensity at each time point on the path by the integral of the maximum safe light intensity range of the material over the path time and then divide by the standard duration to obtain the path light anomaly. The safe light intensity range of the material is obtained experimentally and is the light range that does not affect the color of the material. The shading effect of the covering on the light is considered. By calculating the direct light intensity, the influence of light on the color of the velvet material can be more accurately assessed. For example, during transportation, the material may be partially shaded. Considering only the light intensity without considering the shading effect will lead to an inaccurate assessment of the light influence. Light is one of the important factors that cause the material to fade. Different intensities of light will cause different degrees of damage to the pigment molecules in the material, thereby affecting the color of the material. The path duration is the time to navigate to the designated location.

[0062] S33, obtain the path temperature and humidity anomaly by multiplying the temperature and humidity anomaly of the material color by the temperature and humidity influence coefficient, obtain the path light fading influence anomaly by adding the path temperature and humidity anomaly and the path light fading influence anomaly, obtain the path light fading influence anomaly by adding the path temperature and humidity anomaly and the path light fading influence anomaly, which can comprehensively consider the influence of temperature and humidity and light on the color of the velvet material, and can reasonably allocate the relative importance of temperature and humidity and light on the color of the material by weighting the path temperature and humidity anomaly by the temperature and humidity influence coefficient, and can obtain the comprehensive path light fading influence anomaly index by adding the weighted path temperature and humidity anomaly and the path light fading influence anomaly;

[0063] S34, obtain the road surface flatness of each material transportation path, obtain the average vibration amplitude and average vibration frequency of the corresponding vehicle under the corresponding road surface flatness, wherein the road surface flatness is obtained by scanning the height of each point on the road surface, and the standard deviation of the height of each point on the road surface relative to the reference surface is obtained, the vehicle vibration anomaly is obtained by multiplying the standardized vibration frequency of the corresponding vehicle and the standardized vibration amplitude, the path vibration anomaly is obtained by integrating the vehicle vibration anomaly on the path length and dividing by the standard path degree, and the standardization here is divided by the standard value, and the vehicle vibration amplitude standard value and the vibration frequency standard value are obtained by statistical experiment during transportation without negative impact on the transported material;

[0064] Step S4, analyze the material transportation influence by comprehensively analyzing the product petal deformation influence analysis result and the light fading influence analysis result in the product transportation process;

[0065] In this embodiment, the material transportation anomaly analysis in step S4 includes the following specific contents:

[0066] The path vibration abnormality, the petal deformation influence coefficient, the path fading influence abnormality, and the fading abnormality are obtained, the petal deformation abnormality value is obtained by dividing the path vehicle vibration abnormality by the petal deformation influence coefficient, the material fading abnormality value is obtained by multiplying the path fading influence abnormality and the fading abnormality, and the path transportation material abnormality is obtained by weighted summation of the obtained petal deformation abnormality value and the material fading abnormality value. The scheme comprehensively considers multiple factors such as path vibration abnormality, petal deformation influence coefficient, path fading influence abnormality, and fading abnormality. In the actual path transportation process, the material may be damaged by multiple different types of damage, and only focusing on a single factor cannot accurately reflect the real damage of the material. By comprehensively considering these factors, the influence of path transportation on the material can be comprehensively evaluated, and more comprehensive information can be provided for quality assurance in the transportation process. The petal deformation abnormality value is obtained by dividing the path vehicle vibration abnormality by the petal deformation influence coefficient. This calculation method is based on the causal relationship between path vehicle vibration and petal deformation. Vehicle vibration is an important factor leading to petal deformation, and the petal deformation influence coefficient considers the characteristics of the petal itself and other factors that may affect deformation. Through this calculation method, the influence of vehicle vibration on petal deformation can be more accurately reflected. The material fading abnormality value is obtained by multiplying the path fading influence abnormality and the fading abnormality. This is because there is a synergistic effect between the path fading influence abnormality and the fading abnormality. Path environmental factors (such as light, temperature, etc.) may affect the fading process of the material, and the fading characteristics of the material itself also affect the final fading. Multiplying these two factors can more comprehensively consider their comprehensive influence on the fading of the material. The petal deformation abnormality value and the material fading abnormality value are weighted and summed to obtain the path transportation material abnormality. This is based on the fact that different types of damage have different importance to the transported material. The weight acquisition method here is: obtaining the customer's historical attention to material fading and material loss, and setting the weight according to the proportion of the attention degree;

[0067] Step S5, based on the material transportation influence analysis result, the material transportation path is selected, and is transmitted to the client through the blockchain;

[0068] In this embodiment, the material transportation path selection in step S5 includes the following specific contents:

[0069] The path transportation material outliers of all planned paths are obtained, the path corresponding to the smallest transportation material outlier is set as the material transportation path, the material transportation path is selected for transportation of the velvet flower material, the smart contract in the blockchain network automatically records and verifies the selected material transportation path information, the smart contract is triggered when the path screening is completed, the key data of the path such as the starting point, the ending point and the passing place are packaged and arranged, a data packet containing complete path information is formed, the data packet is encrypted, an advanced encryption algorithm such as asymmetric encryption is used, the path data packet is encrypted using the public key of the client, only the client can decrypt using the corresponding private key, the blockchain node broadcasts the encrypted path information to the entire blockchain network, the client establishes a connection with the node through its unique identity in the blockchain network, sends a request to the blockchain network, and queries the selected material transportation path, the blockchain node receives the request, extracts the encrypted path information from the distributed ledger, and sends it to the client, the client uses its private key to decrypt the received encrypted path information, and thus obtains the clear and accurate material transportation path.

[0070] Meanwhile, it needs to be further explained that the acquisition method of the unexplained setting parameters such as the weight in the embodiment is as follows: the production and storage conditions of the historical velvet flower materials are obtained, the transportation path conditions and the light conditions in the logistics transportation process of the velvet flower products are obtained, the real judgment result of whether the velvet flower materials after transportation meet the requirements is obtained, the historical acquisition data is introduced into the material transportation influence analysis and prediction result obtained in each step of the embodiment, the actual result and the calculation result of the embodiment are introduced into the fitting software, preferably the matlab fitting software, the data is continuously fitted, the value of the setting parameter with the maximum accuracy rate meeting the judgment and prediction is obtained, and the specific steps of fitting include: data acquisition and preprocessing (arranging and cleaning the abnormal values of the historical data of production, storage and logistics), feature extraction and model selection (selecting the key variables such as temperature, humidity and light, and establishing a regression or classification model), model training and parameter optimization, error analysis and verification (calculating the mean square error or cross-validation generalization ability), and finally updating the model (dynamically adjusting the parameters combined with new data), the entire process realizes algorithm fitting and visualization verification by using the matlab tool, so that the prediction result meets the actual requirements;

[0071] It should be noted that the embodiment has the following advantages and benefits: through the blockchain technology, the production, storage, logistics transportation and other data of the velvet flower material are comprehensively obtained, the data security is ensured and the data is not tamperable; the petal deformation influence analysis, the light fading influence analysis, the material transportation abnormality analysis and the material transportation influence analysis are performed by comprehensively considering the velvet flower material and the transportation path, the loss that the material may suffer in the transportation process is comprehensively and accurately evaluated, and the path with the minimum loss is dynamically selected; finally, the selected path is safely transmitted to the client by using the blockchain smart contract and the encryption technology, the transportation loss can be effectively reduced, and the material quality can be ensured.
