Description

Technical Field

[0001] This invention belongs to the field of information management technology for agricultural wholesale markets, specifically relating to an intelligent trading terminal for agricultural wholesale markets and its trading method. Background Technology

[0002] As the core hub of the agricultural product distribution system, agricultural wholesale markets undertake the functions of collection, trading, and distribution of bulk agricultural products. With the rapid development of emerging business models such as fresh food e-commerce and smart agricultural trade, traditional agricultural wholesale markets are facing severe challenges in terms of transaction efficiency, fund settlement, information transparency, and food safety traceability.

[0003] In existing technologies, some agricultural wholesale markets have already introduced information management systems. For example, some systems have implemented transaction order management, inventory monitoring, and data analysis functions through a back-end management platform; others provide online transaction access for merchants through mobile or PC terminals. However, existing solutions still have the following shortcomings:

[0004] In existing technologies, transactions often rely on merchants using their mobile phones or computers, and wholesale markets lack dedicated smart transaction terminals. Identity verification, card payment, and traceability are scattered across different devices and systems, resulting in low efficiency, complex operations, and potential data inconsistencies. Furthermore, the lack of a real-time linkage mechanism between the transaction terminal and the back-end service platform prevents simultaneous inventory deduction, fund settlement, and blockchain-based evidence storage upon payment completion.

[0005] While some existing solutions feature user interfaces, the interaction layer lacks tight coupling with backend business logic such as transaction execution, supply chain management, and data analysis. For example, the wholesale shopping guide function only provides static merchant recommendations and fails to provide intelligent guidance based on real-time customer flow data, procurement route optimization, and inventory dynamics; the payment function lacks automated linkage with the settlement cycle, fund allocation, and transaction card account system, still relying on manual reconciliation.

[0006] Most prepaid cards or membership cards commonly used in farmers' markets are single-type cards, lacking features such as hierarchical management of primary and secondary cards, payment limit control, and multi-channel reconciliation. Top-ups, withdrawals, and transaction record inquiries often require navigating through multiple systems, resulting in a poor user experience, long settlement cycles, and cumbersome reconciliation processes.

[0007] Agricultural product traceability information is typically provided by a separate system, independent of the transaction system. Consumers or wholesale buyers cannot easily obtain traceability information such as the origin, testing reports, and transportation routes of the agricultural products they purchase, resulting in high trust costs and making it difficult to achieve full-chain traceability "from farm to table".

[0008] Some existing technical solutions list various advanced technologies such as smart contracts, blockchain, IoT, and big data analytics in their specifications, but these technologies lack organic integration and fail to form a collaborative technical solution to address practical business problems. Independent claims often contain too many technical features, resulting in an overly narrow scope of protection that is easily circumvented. Summary of the Invention

[0009] To address the shortcomings of existing technologies, the purpose of this invention is to provide an intelligent agricultural product wholesale trading terminal and its trading method that can deeply integrate intelligent trading terminals with trading service platforms, achieve integrated transaction payment and settlement, support primary and secondary card management, combine wholesale guidance and traceability query, and rationally deploy multiple technical features.

[0022] Preferably, the transaction card includes a primary card and a secondary card; the transaction card management entry includes a primary card activation control and a secondary card activation control; when an activation request is initiated through the primary card activation control, the processor controls the identity collection unit to read the ID card information, controls the transaction card read / write unit to read the blank card information, generates the primary card, and activates it; when an activation request is initiated through the secondary card activation control, the processor first verifies the primary card information through the transaction card read / write unit, and then generates a secondary card associated with the primary card.

[0023] Another technical problem to be solved by this invention is to provide a smart transaction method for agricultural product wholesale, comprising: displaying a main transaction interface through a display unit, wherein the main transaction interface includes at least a transaction card management entry, a wholesale guide entry, a traceability query entry, and a payment entry; responding to a transaction card operation request initiated through the transaction card management entry, collecting identity information through an identity collection unit, reading card information through a transaction card read / write unit, generating or verifying a transaction card, and synchronizing transaction card account information to a service platform through a communication unit; responding to a purchase request initiated through the wholesale guide entry, obtaining recommended merchants, recommended products, and purchase routes generated based on purchase needs and historical transaction data through a communication unit, and displaying them on the display unit for navigation; responding to a payment request initiated through the payment entry, completing transaction card deduction through a transaction card read / write unit, and uploading transaction records to a service platform for settlement and inventory linkage through a communication unit.

[0024] Preferably, the procurement route is generated based on the market stall layout, real-time customer flow data, and preset optimization rules; the optimization rules include the shortest path rule, the least waiting time rule, and the highest procurement efficiency rule, and the priority is dynamically adjusted according to user preferences.

[0025] Preferably, the method further includes: obtaining cash transaction data, online transaction data, and card balance from the service platform through the communication unit, and generating a transaction data summary interface on the display unit; the service platform connects with multiple payment channels through API interfaces, automatically generates settlement statements according to the agreed settlement cycle, and settles funds with buyers and sellers.

[0026] Preferably, the transaction record includes the transaction time, amount, payment channel, and product traceability identifier; after the transaction record is uploaded to the service platform through the communication unit, the service platform writes the key information in the transaction record into the blockchain and triggers the smart contract to execute inventory deduction and fund distribution.

[0027] Preferably, the recommended merchants and products are generated by the service platform using a big data analysis model. The big data analysis model is based on historical transaction data, buyer purchase preferences and real-time inventory data, and uses time series analysis or regression analysis methods to predict purchasing trends and generate replenishment suggestions.

[0028] Another technical problem to be solved by the present invention is to provide an intelligent trading system for agricultural product wholesale, comprising: an intelligent trading terminal for agricultural product wholesale as described in any of the above claims; and an agricultural product wholesale trading service platform, connected to the terminal via a communication network, for receiving transaction card account information, transaction records and traceability requests uploaded by the terminal, and performing fund settlement, inventory linkage, data analysis and blockchain evidence storage.

[0029] Another technical problem to be solved by the present invention is to provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the intelligent trading method for wholesale agricultural products as described in any of the above claims.

[0030] The beneficial effects of this invention are as follows:

[0031] By setting up intelligent trading terminals for agricultural product wholesale, identity collection, transaction card reading / writing, display, and communication units are integrated into one unit, establishing real-time data interaction with the agricultural product wholesale trading service platform. The trading terminal not only serves as a front-end interaction carrier but also undertakes functions such as identity verification, transaction card payment, and local data caching. The service platform is responsible for fund settlement, inventory linkage, data analysis, and blockchain notarization, forming an integrated collaborative architecture of "front-end intelligent terminal + back-end service platform," significantly improving transaction efficiency and data consistency.

[0032] Through the transaction card management portal and the transaction card reader / writer unit working in tandem, the system supports the generation, verification, and activation of primary and secondary cards, forming a linked account system that facilitates family-run or team-based operations for wholesale merchants. Payment is processed via the transaction card, with transaction records uploaded to the service platform in real time. The service platform connects with multiple payment channels through API interfaces, automatically generating settlement statements according to the agreed settlement cycle and settling funds with buyers and sellers. This achieves full automation from payment to settlement, reducing manual reconciliation costs.

[0033] The wholesale shopping guide provides access to recommended merchants, products, and shopping routes generated based on purchasing needs and historical transaction data. The shopping routes are generated based on market stall layout, real-time customer flow data, and preset optimization rules, including shortest path, minimum waiting time, and maximum purchasing efficiency rules, with priorities dynamically adjusted according to user preferences. This feature combines intelligent recommendations with real-time market conditions to provide buyers with accurate and efficient purchasing guidance, reducing purchasing time costs.

[0034] By integrating a traceability query portal into the transaction terminal, users can check the origin information, testing reports, transportation routes, and merchant qualifications of agricultural products at any time before and after a transaction. Simultaneously, after transaction records are uploaded to the service platform via the communication unit, the service platform writes key information from the transaction records into the blockchain and triggers smart contracts to execute inventory deductions and fund distribution. This deep integration of transaction and traceability data ensures that every transaction can be traced back to its source, improving food safety management and consumer trust.

[0036] Figure 2 A flowchart illustrating an embodiment of the present invention provides an intelligent trading terminal for agricultural product wholesale and its trading method. Detailed Implementation

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0038] Example

[0039] See Figure 1-2 As shown, an intelligent trading terminal for agricultural product wholesale includes: a display unit, an identity acquisition unit, a transaction card reading and writing unit, a communication unit, and a processor.

[0040] The display unit is used to display the transaction interaction interface, preferably a touch screen, supporting users to initiate various operation requests via touch. The identity acquisition unit is used to collect user identity information, including but not limited to one or more combinations of an ID card reader, a facial recognition camera, and a fingerprint acquisition module. The transaction card reader / writer unit is used to read or write transaction card information, supporting contact IC card reading / writing, contactless RFID card reading / writing, and magnetic stripe card reading. The communication unit is used to establish data interaction with the agricultural product wholesale transaction service platform, supporting mobile communication, Wi-Fi, and wired network connections. The processor is connected to the display unit, identity acquisition unit, transaction card reader / writer unit, and communication unit respectively, and is used to execute preset control logic and data processing procedures.

[0041] In a preferred embodiment, the processor is configured to display a main transaction interface through the display unit, the main transaction interface including at least a transaction card management entry, a wholesale guide entry, a traceability query entry, and a payment entry.

[0042] When a user initiates a transaction card operation request through the transaction card management portal, the processor controls the identity collection unit to collect identity information, controls the transaction card reading and writing unit to read card information, generates or verifies the transaction card, and synchronizes the transaction card account information to the service platform through the communication unit.

[0043] When a user initiates a purchase request through the wholesale guide portal, the processor obtains recommended merchants, recommended products, and purchase routes based on the purchase demand and historical transaction data through the communication unit, and displays them on the display unit for navigation.

[0044] When a user initiates a payment request through the payment portal, the processor controls the transaction card reading and writing unit to complete the transaction card deduction, and uploads the transaction record to the service platform through the communication unit for settlement and inventory linkage.

[0045] When a user initiates a traceability request through the traceability query portal, the processor obtains information on the origin of agricultural products, testing reports, transportation routes, and merchant qualification information through the communication unit, and displays them on the display unit.

[0046] This embodiment further limits the transaction card management function based on the aforementioned embodiments.

[0047] The transaction card includes a primary card and a supplementary card. The primary card has full management permissions, including card opening, reporting loss, cancellation, and credit limit settings; the supplementary card is associated with the primary card and is authorized for use by the primary cardholder, suitable for scenarios involving division of labor among family members or teams.

[0048] The transaction card management entry point includes a primary card activation control and a secondary card activation control. When an activation request is initiated through the primary card activation control, the processor controls the identity collection unit to read the user's ID card information and controls the transaction card read / write unit to read the blank card information, generating and activating the primary card. During the activation process, the processor also prompts the user to set a transaction password, bind a mobile phone number, and set a daily transaction limit through the display unit.

[0049] When an activation request is initiated through the supplementary card activation control, the processor first verifies the primary card information through the transaction card read / write unit. After successful verification, it reads the new card information and generates a supplementary card associated with the primary card. The transaction limit and validity period of the supplementary card are configured by the primary cardholder through the transaction card management sub-interface.

[0050] All records of card opening, information modification, and card loss reporting are uploaded to the service platform through the communication unit. The service platform generates operation logs to support subsequent auditing and traceability.

[0051] When a user initiates a purchase request through the wholesale guide portal, the display unit shows the wholesale guide sub-interface. This sub-interface includes purchase request input controls, historical data matching controls, filter condition setting controls, recommended results display controls, and navigation function controls.

[0052] Users input the purchase category, quantity, and price range as requirements parameters through the purchase requirement input control. Optionally, the purchase requirement input control supports file upload functionality, allowing users to upload purchase requirement files. The processor then performs format validation on the files, extracts the purchase category, quantity, and price range, and generates structured purchase requirement data.

[0053] After a user triggers the historical data matching control, the processor retrieves the user's historical transaction records from the service platform through the communication unit, analyzes frequently purchased categories, preferred prices, and high-frequency merchants, and generates matching recommendation data.

[0054] Based on procurement demand parameters and matching recommendation data, the service platform uses collaborative filtering and content-based recommendation algorithms to generate lists of recommended merchants and products. Simultaneously, the platform acquires market stall layout data and real-time customer flow data, combining this with preset optimization rules to generate procurement routes.

[0055] The optimization rules include the shortest path rule, the least waiting time rule, and the highest procurement efficiency rule. Among them, the shortest path rule preferentially selects the merchant path closest to the user's current location; the least waiting time rule dynamically adjusts the path order according to the queuing duration of each merchant; the highest procurement efficiency rule comprehensively considers the quantity of procurement varieties, merchant distribution, and expected stay time to generate a procurement plan with the shortest total time consumption. The priority of the optimization rules can be dynamically adjusted according to user preferences. For example, the user can check the "Prefer to avoid queuing" option in the filter condition setting control to adjust the priority of the least waiting time rule to the highest.

[0056] The recommended result display control shows the matching merchant information, product details, and procurement route in the form of a list or card. After the navigation function control responds, the display unit shows the navigation interface based on the market layout map, guiding the user to walk to the target merchant booth and updating the path according to the real-time passenger flow data during the user's progress.

[0057] When the user initiates a payment request through the payment entrance, the transaction card reading and writing unit reads the transaction card information, and the processor verifies the balance or credit limit of the transaction card. After the verification is passed, the deduction operation is completed. After the deduction is successful, the processor generates a transaction record including the transaction time, amount, payment channel, product list, merchant information, and product traceability identifier, and uploads it to the service platform in real time through the communication unit.

[0058] After receiving the transaction record, the service platform triggers the following linkage operations:

[0059] First, inventory linkage: The service platform calls the order and inventory management module according to the product list in the transaction record to automatically deduct the inventory quantity of the corresponding merchant. When the inventory quantity is lower than the preset threshold, the system automatically generates a replenishment suggestion and notifies the merchant.

[0060] Second, fund settlement: The service platform connects to payment channels such as Alipay, WeChat Pay, and UnionPay through API interfaces and initiates a fund transfer request according to the transaction record. At the same time, the service platform automatically generates a settlement statement according to the settlement cycle agreed between the merchant and the buyer, recording the relevant information of each transaction, including the transaction time, amount, payment channel, and payment status. After the settlement is completed, the service platform pushes the settlement result to the transaction terminal through the communication unit.

[0061] Third, blockchain evidence preservation: The service platform writes the key information in the transaction record into the blockchain network. Each transaction is recorded in the form of a block, and all blocks are connected to the previous block through a hash value to form an immutable transaction ledger. At the same time, the service platform calls the smart contract in the blockchain to automatically execute the transaction verification and fund splitting logic to ensure the authenticity of the transaction and the security of the funds.

[0062] Fourth, data analysis: The service platform automatically collects transaction data such as product sales volume, price fluctuations, and inventory changes through API interfaces, and uses big data analytics to clean, mine, and analyze the data. Specifically, the service platform uses machine learning models and deep learning algorithms such as time series analysis, regression analysis, and cluster analysis to predict market trends, identify changes in market demand and product sales dynamics, and provide merchants with pricing suggestions and procurement strategy support.

[0063] When a user initiates a traceability request through the traceability query portal, the display unit shows the agricultural product traceability query sub-interface. This sub-interface includes controls for displaying origin information, viewing test reports, tracking transportation routes, viewing merchant qualifications, and providing feedback and evaluation.

[0064] Users can view the origin information, planting or breeding information, and the name of the cooperative or base for agricultural products through the origin information display control.

[0065] Users can view the pesticide residue and heavy metal test results, testing institution name, testing date, and quality inspection number for agricultural products through the test report viewing control. Test reports are displayed in PDF or image format and can be downloaded and printed.

[0066] Users can use the transportation route tracking control to view information about the vehicles transporting agricultural products, transportation time, transit points, and temperature and humidity records during transportation.

[0067] Users can view a merchant's business license, operating permit, food safety permit, and other qualification documents through the merchant qualification viewing control, and it also supports automatic reminders of the qualification validity period.

[0068] Users can evaluate and provide feedback on merchants' product quality, service attitude, and contract fulfillment through feedback controls. The evaluation data is uploaded to the service platform via communication units and synchronized to the merchant's credit profile, serving as an important reference factor for subsequent wholesale and retail recommendations.

[0069] The payment management sub-interface includes a payment limit configuration control, a payment switch control, a channel parameter management control, a channel configuration management control, an order query control, and a reconciliation control.

[0070] Users can configure daily online top-up limits, withdrawal limits, and single transaction limits for their transaction cards using the payment limit configuration control. Users can enable or disable the top-up and withdrawal functions of the transaction card using the payment toggle control, which is suitable for scenarios involving lost cards or temporary control.

[0071] Users can add, modify, or delete payment channel call parameters for transaction cards through the channel parameter management control. Users can also set the front-end display name, fee rate, invocation method, and allocation method of payment channels through the channel configuration management control, supporting dynamic selection of the optimal payment channel based on merchant type and transaction amount range.

[0072] Users can view the status of recharge, withdrawal, and consumption orders for their transaction cards through the order query control. The system supports filtering by time range, order status, and payment channel, and users can also reprint transaction vouchers.

[0073] Users can use the reconciliation control to compare the number of incoming payments, withdrawals, amounts, and transaction fees on their transaction cards to complete data verification. The reconciliation results are displayed in tabular and chart formats and can be exported to Excel or PDF formats.

[0074] The transaction data summary sub-interface includes a date filter control and a summary display control. Users can input a start date and end date using the date filter control to filter the target statistical time period. In response to a trigger operation on the summary display control, a summary window is displayed, calculating and displaying the transaction card's cash transaction data, online transaction data, and card balance based on a preset formula.

[0075] Each quarter, system administrators use performance testing tools to simulate user access and test the system's response speed under high concurrency. Stress testing and load testing are used to verify the system's processing capacity under a large number of transaction requests. Database performance testing is conducted to evaluate the system's data storage and retrieval capabilities. Application performance management tools are deployed for real-time monitoring, and log analysis tools are used to identify potential bottlenecks and anomalies.

[0076] Meanwhile, system administrators conducted user surveys, using questionnaires, user interviews, and feedback collection channels to understand the usage needs and satisfaction levels of buyers and sellers. By analyzing user behavior data such as page visit frequency, click paths, and function usage frequency within the system, they identified the functions users cared about and system performance bottlenecks.

[0077] The system adopts a modular architecture, separating functional modules such as payment, transaction, inventory management, and user management. Based on quarterly performance evaluations and user feedback, targeted optimizations are made to certain modules. For example, if transaction processing capacity becomes a bottleneck, code optimization, database index optimization, or the addition of a caching layer are performed on the transaction module.

[0078] Furthermore, the system is deployed based on a microservice architecture or containerization technology. When the system load increases, horizontal scaling is achieved by adding microservice instances or expanding containers to ensure the stability and availability of the system under high concurrency scenarios.

[0079] This embodiment provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements the intelligent trading method for wholesale agricultural products as described in any of the foregoing embodiments.

[0080] This embodiment also provides a computer-readable storage medium on which a computer program is stored. When executed by a processor, the program implements the intelligent trading method for wholesale agricultural products described in any of the foregoing embodiments. The computer-readable storage medium can be any form of data storage medium such as ROM, RAM, hard disk, optical disk, or flash memory.

[0081] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention. The implementation of the present invention is not limited thereto. All other modifications, substitutions or alterations made to the above structure of the present invention based on the above content of the present invention, in accordance with ordinary technical knowledge and common practice in the field, without departing from the basic technical idea of ​​the present invention, shall fall within the scope of protection of the present invention.
