[0031] Embodiment one

[0032] As Figure 1 shown, the present application provides a sand and gravel building material transaction data processing method based on a supply chain, wherein the method is applied to a sand and gravel building material transaction data processing system, the system is in communication connection with a sand and gravel transaction cloud platform, and the method comprises the following steps:

[0033] Step S100: obtaining sand demand information of a first user according to the sand and gravel transaction cloud platform;

[0034] Specifically, the sand and gravel transaction cloud platform is a cloud platform for legal and compliant normal transactions between sand and gravel transaction parties, and transactions are carried out within a reasonable transaction price range. By extracting the information of the transaction party demand from the sand and gravel transaction cloud platform, a user is randomly selected from the transaction party as the first user, and the sand and gravel information required by the first user is extracted to obtain the sand demand information. The first user is any user who has a demand for sand and gravel and needs to purchase sand and gravel from the sand and gravel transaction cloud platform. The sand demand information reflects the purchase demand of the first user for sand and gravel, including sand and gravel use, sand and gravel type, sand and gravel composition, quantity required, etc. By extracting the sand demand information of the first user, the demand of the sand and gravel transaction party is accurately obtained, thereby providing reliable information data for the subsequent matching of the transaction parties.

[0035] Step S200: positioning the first user according to the sand demand information based on a supply chain, and obtaining a supply chain positioning result;

[0036] Specifically, according to the sand demand information, the sand use, the transaction sand type are extracted, the supply node of the first user in the sand supply chain is located, and the identity information of the first user is obtained. The supply chain positioning result reflects the supply node of the first user in the entire sand supply chain, and provides a reliable basis for further analyzing the transaction purpose of the first user. The supply chain positioning result includes sand mining, sand pretreatment, process treatment, sand transportation enterprise, sand dealer, etc. The supply chain is a complete set of supply nodes between sand production and use merchants, including sand production node, sand treatment node, sand transportation node, sand sales node, etc.

[0037] Step S300: generating a transaction user library according to the supply chain positioning result;

[0038] Specifically, the position of the first user in the supply chain can be obtained from the supply chain positioning result, and then the transaction object that can meet the demand of the supply chain positioning result is obtained by combining the sand demand information of the first user, thereby obtaining the transaction user library. Preferably, the transaction user library is obtained by searching the suppliers in the sand transaction cloud platform according to the supply chain positioning result. The transaction user library is all users in the sand transaction cloud platform that can meet the demand of the first user and conduct sand transaction with the first user.

[0039] Step S400: collecting sand and building material transaction data sets of each transaction user in the transaction user library;

[0040] Specifically, the sand and building material transaction data of each transaction user in the transaction user library in the sand transaction cloud platform is searched, and data is extracted from multiple dimensions such as transaction object, transaction sand material type, transaction sand quantity, etc., thereby obtaining the sand and building material transaction data set. The sand and building material transaction data set is the transaction record of each transaction user in the sand transaction cloud platform, which can provide data support for analyzing the transaction credibility, transaction success rate, transaction reliability and transactionable sand and building material quality of each transaction user, including sand transaction amount, sand and building material transaction volume, sand and building material transaction frequency, etc.

[0041] Step S500: inputting the sand and building material transaction data set of each transaction user into a sand transaction evaluation model, and obtaining a transaction evaluation index according to the sand transaction evaluation model, wherein the sand transaction evaluation model is embedded in a cloud processor;

[0042] Further, as shown in Figure 2 Step S500 further includes:

[0043] Step S510: obtaining a transaction object class according to the supply chain positioning result;

[0044] Step S520: classifying the to-be-traded user library by the transaction object class to obtain a transaction user classification result;

[0045] Step S530: establishing a plurality of sandstone transaction evaluation sub-models according to the transaction user classification result, wherein each sandstone transaction evaluation sub-model corresponds to a type of transaction user;

[0046] Step S540: generating the sandstone transaction evaluation model by using the plurality of sandstone transaction evaluation sub-models.

[0047] Further, the step S540 of the embodiment of the present application further comprises:

[0048] Step S541: obtaining transaction process attribute information by performing process attribute analysis according to the sandstone demand information;

[0049] Step S542: determining an evaluation transaction index according to the transaction process attribute information;

[0050] Step S543: taking the evaluation transaction index as an evaluation dimension in each sandstone transaction evaluation sub-model, and outputting a plurality of transaction evaluation results corresponding to the plurality of sandstone transaction evaluation sub-models.

[0051] Specifically, the sandstone transaction evaluation model is a functional model for performing multi-dimensional intelligent analysis on the transaction conditions of each transaction user by performing data analysis on the sandstone building material transaction data set as input data. The transaction evaluation index is obtained by evaluating the sandstone building material transaction data of each transaction user, and reflects the transaction matching degree of each transaction user. By embedding the sandstone transaction evaluation model in a cloud processor, the reliability of input information and output information can be ensured. By storing and processing data on a third-party platform, the data privacy of both parties in the transaction can be ensured, and information leakage can be prevented.

[0052] Specifically, the transaction object class of the transaction party who wants to trade in the sand and stone building material transaction is obtained according to the supply chain positioning result. The transaction user classification result is obtained by classifying the transaction user library according to the transaction object class, in other words, according to the category to which the transaction object belongs, and according to the different supply nodes of the supply chain. The transaction user classification result is the node in the supply chain where the transaction user is located, and the classification result obtained after the users in the same node are classified into a class. According to the category of the user in the transaction user classification result, a sand and stone transaction evaluation sub-model for evaluating the transaction information of each transaction user in each transaction user category is established, and each sand and stone transaction evaluation sub-model corresponds to a category in the transaction user classification result. The multiple sand and stone transaction evaluation sub-models have different evaluation indicators and different nodes in the supply chain corresponding to the content of the evaluation due to the different categories of the evaluation objects, and the input data is the mapping transaction data group, and the output data is the transaction evaluation index. The sand and stone transaction evaluation model is obtained by connecting the multiple sand and stone transaction evaluation sub-models in parallel.

[0053] Specifically, the transaction flow attribute information is obtained by analyzing the attributes of the sand and stone demand information in the supply process. The transaction flow attribute information is the purpose information of the transaction party in the sand and stone transaction, including first purchase, purchase according to the predetermined order, replenishment, and end-of-life processing. The transaction index for evaluation is determined according to different transaction flow attribute information. The evaluation transaction index is a multi-dimensional evaluation of the transaction flow attribute information, thereby obtaining the transaction quality index, including logistics index such as logistics turnover storage time, logistics transportation speed, and logistics transportation quality; material processing index such as material processing yield, and material process maturity; and raw material index such as raw material quality, raw material defect degree, and raw material quantity. The evaluation transaction index is used as an evaluation dimension in each sand and stone transaction evaluation sub-model, the data in the input sub-model is analyzed according to the evaluation transaction index, and multiple transaction evaluation results are obtained.

[0054] Further, as shown in Figure 3 The step S500 further includes:

[0055] Step S550: reading the building material transaction data set stored in the user terminal system of the first user;

[0056] Step S560: reading the sand and stone building material transaction data set stored in the user terminal system of each transaction user;

[0057] Step S570: One-to-many mapping is performed on the building material transaction data set and the sandstone building material transaction data set, and a mapping transaction data group is output, wherein each group of mapping transaction data includes two groups of transaction data sets;

[0058] Step S580: According to the mapping transaction data group, a plurality of transaction evaluation indexes are obtained by inputting into the plurality of sandstone transaction evaluation sub-models.

[0059] Specifically, the building material transaction data set is obtained by extracting record data generated in the process of the user of the first user terminal system of the sandstone transaction cloud platform performing transactions. The building material transaction data set is data information of the first user performing sandstone building material transactions through the sandstone transaction cloud platform, including sandstone building material types, transaction time, transaction amount, transaction purpose, quality requirements, and the like. Further, the sandstone building material transaction data set is obtained by extracting data information of the sandstone building material transactions performed by each transaction user through the sandstone transaction cloud platform, including transaction objects, transaction time, order amount, transaction frequency, delivery time, transaction evaluation, and the like.

[0060] Preferably, one-to-many mapping is performed on the building material transaction data set and the sandstone building material transaction data set, that is, the building material transaction data set corresponding to one first user is matched with the sandstone building material transaction data sets corresponding to a plurality of transaction users, respectively, to obtain the mapping transaction data set. The mapping transaction data group contains a plurality of matching results, and each mapping matching result corresponds to data including two groups of transaction data sets, thereby providing analysis data for subsequent analysis of the matching degree between the first user and the transaction user. By inputting the corresponding plurality of sandstone transaction evaluation sub-models according to the categories corresponding to the to-be-traded users of the mapping transaction data group, respectively, transaction evaluation is performed, thereby obtaining indexes for evaluating different transaction matching results, that is, the plurality of transaction evaluation indexes.

[0061] Further, the step S580 of the embodiment of the present application further includes:

[0062] Step S581: Privacy data of the building material transaction data set is identified to obtain a first transaction privacy data set;

[0063] Step S582: The first transaction privacy data set is encrypted by the first user to output a first encrypted transaction data set;

[0064] Step S583: Privacy data of the sandstone building material transaction data set is identified to obtain a second transaction privacy data set;

[0065] Step S584: encrypting the second transaction privacy data set by the corresponding transaction user, and outputting a second encrypted transaction data set;

[0066] Step S585: uploading the first encrypted transaction data set and the second encrypted transaction data set to a third-party platform for decryption, and obtaining the plurality of transaction evaluation indexes.

[0067] Specifically, the privacy information data related to the first user in the building material transaction data set is identified, preferably, the privacy keywords such as the transaction average price, the transaction quantity, and the transaction object are obtained, and the data in the building material transaction data set that matches the privacy keywords is identified, and the first transaction privacy data set is obtained after being summarized. The first transaction privacy data set reflects the data information that needs to be protected by the first user and cannot be disclosed or leaked. Preferably, the first transaction privacy data set is encrypted by using a private key such as DES, AES, or using a digital certificate, thereby obtaining the first encrypted transaction data set. The first encrypted transaction data set is obtained by encrypting the first transaction privacy data set, and the information in the data set can be obtained by using the corresponding decryption key. The privacy data in the sandstone building material transaction data set is identified in the same way, and the second transaction privacy data set is obtained. The second transaction privacy data set is the data information that needs to be protected by each transaction object and cannot be disclosed or leaked. The second encrypted transaction data set is obtained by selecting a different encryption method such as asymmetric encryption RSA for data encryption. The second encrypted transaction data set reflects the data encryption of the sensitive data of each transaction user. The first encrypted transaction data set and the second encrypted transaction data set are uploaded to the third-party platform, and the data in the data set is obtained after being decrypted according to the corresponding decryption method, thereby being input into the plurality of sandstone transaction evaluation sub-models for intelligent evaluation, and the plurality of transaction evaluation indexes are obtained.

[0068] Further, the step S580 of the embodiment of the present application further includes:

[0069] Step S586: building the sandstone transaction evaluation model, wherein the sandstone transaction evaluation model includes a material demand evaluation index, a cycle demand evaluation index, and a cost demand evaluation index;

[0070] Step S587: obtaining a material demand matching degree, a cycle demand matching degree, and a cost demand matching degree according to the sandstone transaction evaluation model;

[0071] Step S588: weight calculation is performed according to the material demand matching degree, the period demand matching degree and the cost demand matching degree, and the plurality of transaction evaluation indexes are generated.

[0072] Specifically, the material demand evaluation index is an index for limiting the material requirements of sand and stone building materials, including material quality, material purity, material quantity, etc. The period demand evaluation index is an index for limiting the supply period of sand and stone materials, including the supply period, the logistics turnover period, the transaction amount turnover period, etc. The cost demand evaluation index is an index for limiting the cost spent in the transaction process of sand and stone building materials, including the time cost index, the logistics cost index, the raw material cost index, the loss cost index, etc. By obtaining historical transaction data from the sand and stone building material transaction cloud platform, the historical sand and stone building material transaction data set, the historical building material transaction data set and the historical transaction evaluation index are obtained as a training set, and the historical transaction evaluation index is data labeled. The sand and stone transaction evaluation model based on the BP neural network is trained by using the training set, and the historical transaction evaluation index with data labeling is used as supervision data to supervise the training process until the model training converges, so as to obtain the sand and stone transaction evaluation model.

[0073] Preferably, the material demand matching degree is obtained by evaluating the matching degree between the sand and stone building material transaction data set and the building material transaction data set through the material demand evaluation index. The period demand matching degree is obtained by evaluating the matching degree between the sand and stone building material transaction data set and the building material transaction data set through the period demand evaluation index. The cost demand matching degree is obtained by evaluating the matching degree between the sand and stone building material transaction data set and the building material transaction data set through the cost demand evaluation index. By setting the weight proportion by the staff, the material demand matching degree, the period demand matching degree and the cost demand matching degree are weighted and calculated, so as to obtain the plurality of transaction evaluation indexes.

[0074] Step S600: determining a first matching user according to the transaction evaluation index, and sending the first matching user to the first user, wherein the first matching user belongs to the to-be-traded user library.

[0075] Further, after generating the plurality of transaction evaluation indexes, the embodiment of the application step S600 further comprises:

[0076] Step S610: judging the plurality of transaction evaluation indexes to obtain an identified transaction user greater than a preset evaluation index;

[0077] Step S620: If the number of identified transaction users is greater than or equal to 2, identify the weights corresponding to the material demand matching degree, the period demand matching degree and the cost demand matching degree respectively to obtain a first weight matching degree;

[0078] Step S630: Sort the identified transaction users according to the size of the first weight matching degree to obtain a first transaction user;

[0079] Step S640: Send the first transaction user to the first user as the first matching user.

[0080] Specifically, the preset evaluation index is an evaluation index that can meet the transaction demand of the first user, which is set by the staff and is not limited herein. By judging the plurality of transaction evaluation indexes, an identified transaction user greater than the preset evaluation index is obtained, which is a user that can meet the preset requirements and can trade. When the number of identified transaction users is greater than or equal to 2, it indicates that the number of users that can trade exceeds the demand, and the identified transaction users can be selected. Further, the corresponding weight matching degree of the identified transaction user in the evaluation process is obtained, i.e., the first weight matching degree, which is a calculation result obtained by weighting the material demand matching degree, the period demand matching degree and the cost demand matching degree according to the set weight proportion. The identified transaction users are sorted in descending order of the first weight matching degree, and the one ranked first is taken as the first transaction user. The first transaction user is the user that first trades sandstone with the first user. Further, the first transaction user is sent to the first user as the first matching user, so that the first user can trade sandstone building materials with it.

[0081] In summary, the embodiments of the present application have at least the following technical effects:

[0082] The embodiments of the present application obtain the sandstone demand information of the first user according to the sandstone transaction cloud platform, and position the position of the first user in the supply chain according to the sandstone supply chain and the demand information, thereby achieving the purpose of analyzing and accurately positioning the demand of the transaction user. Further, according to the supply chain positioning result, a to-be-traded user that can trade with the first user and meet the demand of the first user is obtained, and then the sandstone building material transaction data set of the transaction user is collected to analyze the transaction situation of the transaction user, so as to input it into the sandstone transaction evaluation model for evaluation, thereby achieving the goal of intelligent evaluation of the transaction user. Then, the first matching user is determined according to the transaction evaluation index, and the first matching user is sent to the first user to obtain the transaction object. The technical effects of improving the efficiency of sandstone building material transaction data processing, improving the matching quality of the transaction object, and ensuring the efficient and smooth completion of the transaction are achieved.
