Description

Technical Field

[0001] This invention relates to the field of electronic traceability scale equipment technology, and in particular to an electronic traceability scale for tea trading. Background Technology

[0002] Currently, the four main stages of tea trading—weighing, pricing, payment, and traceability—are independent, leading to problems such as cumbersome operations, low efficiency, inconsistent traceability, and delayed fund transfers. Existing electronic traceability scales mostly only have weighing and traceability information recording functions, lacking an integrated payment module. Tea transactions require weighing on a traceability scale first, followed by manual calculation of the amount, and then payment via third-party payment devices or cash. This not only increases the transaction process but also easily leads to problems such as pricing errors, misappropriation of funds, and disconnect between traceability and transaction information.

[0003] Meanwhile, as the core players in tea production, tea farmers often have to manually process their agricultural benefit card transactions through bank counters or mobile banking, resulting in transaction funds not arriving in real time and affecting their cash flow. Furthermore, existing traceability systems primarily focus on tracing the tea processing and sales stages, lacking comprehensive records of the tea planting origins (such as tea field location, harvesting time, and varieties). This makes it difficult to achieve full-chain traceability "from tea garden to transaction," failing to meet the demands for transparency and standardization in tea transactions and hindering the protection of tea farmers' rights and consumers' right to know. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the existing technology by providing an electronic traceability scale for tea transactions, thereby simplifying the transaction process, ensuring real-time fund arrival, improving the traceability of the entire tea supply chain, and protecting the rights and interests of tea farmers and ensuring transaction transparency.

[0005] This invention provides an electronic traceability scale for tea transactions, comprising a scale body and a host unit. One end of the scale body is fixedly connected to the host unit via a connecting rod. The scale body contains a weighing module. The host unit includes a POS module, a traceability recording module, a payment control module, a display module, and a storage module. The weighing module, POS module, traceability recording module, display module, and storage module are all electrically connected to the payment control module. The payment control module is configured to receive weight signals from the weighing module and transaction signals from the POS module, and control the traceability recording module to generate associated data. Simultaneously, it provides visual output through the display module and persistent data storage through the storage module. The storage module is communicatively connected to a cloud-based traceability platform, and the POS module interfaces with a rural payment integrated service platform and a UnionPay unified payment interface through a payment interface unit.

[0006] Furthermore, the weighing module employs a high-precision calibrated weighing sensor, combined with an analog-to-digital converter (ADC) and a microcontroller, ensuring a weighing accuracy error of no more than ±10g.

[0007] Furthermore, the main unit's casing is an anti-interference casing to shield against external electromagnetic interference.

[0008] Furthermore, the POS machine module includes a password input unit, a farmer benefit card reading unit, a payment interface unit, and a printing unit; the farmer benefit card reading unit uses a contactless card reader, which supports reading the chip information and magnetic stripe information of the tea farmer benefit card to quickly obtain account information; the password input unit uses a privacy keypad, supports password input and verification, and prevents password leakage; the payment interface unit uses the AES-256 encryption algorithm, connects to the UnionPay unified payment interface and the rural payment integrated service platform, and realizes real-time transfer and encrypted transmission of transaction funds.

[0009] Furthermore, the printing unit uses a thermal printer, which can quickly print transaction vouchers and traceability vouchers.

[0010] Furthermore, the traceability recording module includes an information code recognition component, an image acquisition component, a positioning unit, and an information input unit. The information code recognition component is a barcode scanner that can identify traceability marks on tea packaging and automatically obtain preliminary traceability information such as tea planting, processing, and storage. The image acquisition component is a high-definition camera that can inspect tea, collect tea appearance features, and assist in verifying tea varieties and grades. The positioning unit uses GPS and Beidou dual-mode positioning to obtain the geographical location information of the transaction location. The information input unit is a touch input panel that allows manual input of tea farmer identity information, tea field location information, tea variety information, picking time, processing information, etc., to generate a unique traceability code.

[0011] Furthermore, the payment control module includes a unit price preset unit and an anomaly warning unit. The unit price preset unit can preset the corresponding unit price for various tea varieties and grades, supports manual adjustment of the unit price, and automatically synchronizes it to the pricing system after adjustment. The anomaly warning unit can issue warnings for abnormal weighing data and abnormal transaction amounts, reminding operators to verify. After receiving the weight data from the weighing module, the payment control module automatically calculates the amount payable (amount payable = weight × preset unit price), receives the Huinong Card account information and transaction password from the POS machine module, and links with the rural payment integrated service platform and UnionPay unified payment interface through the payment interface unit to complete password verification and fund transfer. At the same time, it binds the transaction information with traceability information and traceability code to generate integrated data.

[0012] A method for using an electronic traceability scale for tea trading, characterized by the following steps: 1) Preliminary preparation: Operators manually enter the tea source information through the information input unit of the traceability record module, or scan the traceability mark on the tea packaging through the information code recognition component to obtain the preliminary traceability information; obtain the geographical location information of the transaction location through the positioning unit, and generate a unique traceability code after entering it into the system; preset the corresponding unit price according to the tea variety and grade (such as first grade, second grade) through the unit price preset unit of the payment control module; 2) Weighing and pricing: Place the tea to be traded on the weighing platform of the weighing module. The weighing module accurately acquires the weight data of the tea and transmits the weight data to the payment control module. The payment control module, in conjunction with the preset unit price, automatically calculates the amount payable and displays the tea weight, unit price, and amount payable through the display module. 3) Payment Operation: The tea farmer places their agricultural benefit card near the agricultural benefit card reading unit of the POS machine module. The agricultural benefit card reading unit quickly reads the agricultural benefit card account information and displays it on the display module. The operator or tea farmer enters the transaction password through the password input unit. The payment control module verifies the transaction password. If the verification is successful, the control payment interface unit transfers the transaction amount directly from the transacting party's account to the tea farmer's agricultural benefit card through the UnionPay unified payment interface and the rural payment integrated service platform. If the password verification fails, the display module prompts "Incorrect password, please re-enter" until the password verification is successful. 4) Data Binding: After payment is completed, the payment control module immediately receives the payment success feedback information and binds the transaction information (transaction amount, transaction time, transaction party information, last four digits of the Huinong Card account) with the tea traceability information (traceability code, tea farmer information, tea field location, tea variety, and picking time) to generate integrated transaction-traceability data. This data is then synchronously stored in the storage module and uploaded to the cloud traceability platform to achieve data retention and synchronization. 5) Voucher Output: The operator triggers the print command through the display module. The printing unit of the POS machine module prints the transaction voucher and the traceability voucher. The transaction voucher includes information such as the transaction amount, transaction time, last three digits of the Huinong Card account, and transaction success indicator. The traceability voucher includes the traceability code, tea origin information, and transaction information. The tea farmer and the trading party each keep a copy, completing the entire tea transaction process. If the network is interrupted during the transaction, the system automatically enters offline mode, temporarily storing the transaction and traceability data. After the network is restored, it is automatically synchronized to the storage module and the cloud traceability platform to ensure that the data is not lost.

[0013] Compared with the prior art, the present invention has the following outstanding advantages: 1. This invention achieves integrated operation and simplifies the transaction process: It integrates weighing, pricing, POS payment, agricultural benefit card disbursement, and traceability recording into one unit, eliminating the need for additional third-party payment and traceability equipment. All operations can be completed using this traceability scale during tea transactions, solving the problems of fragmented transaction processes, cumbersome operations, and low efficiency, and greatly improving the efficiency of tea transactions. 2. Improve the entire tea supply chain traceability and enhance transaction transparency: The traceability record module comprehensively records information about the origin of tea (tea farmers, tea fields, varieties, harvesting time, etc.). Combined with positioning units and image acquisition components, it realizes full-chain traceability from "origin to transaction location to transaction information," generating a unique traceability code that can be queried through a cloud platform. This ensures that the origin of tea is traceable and its destination is trackable, protecting consumers' right to know and facilitating regulatory authorities to supervise tea transactions, thus promoting the standardization of tea trading. The traceability data conforms to industry standards, ensuring that the data is accurate, unique, and complete. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 and 2 As shown, the present invention includes a traceability scale body 1 and a host 2. One end of the traceability scale body 1 is fixedly connected to the host 2 unit via a connecting rod 3. The traceability scale body 1 is equipped with a weighing module. The host 2 includes a POS machine module 21, a traceability record module, a payment control module, a display module 22, and a storage module. The weighing module, the POS machine module 21, the traceability record module, the display module 22, and the storage module are all electrically connected to the payment control module.

[0017] The payment control module is configured to receive the weight signal from the weighing module and the transaction signal from the POS machine module 21, and control the traceability record module to generate associated data. It also performs visualization output through the display module 22 and persistent data storage through the storage module. The storage module is communicatively connected to the cloud traceability platform, and the POS machine module 21 is connected to the rural payment integrated service platform and the UnionPay unified payment interface through the payment interface unit.

[0018] In this embodiment, the weighing module adopts a high-precision calibrated weighing sensor, combined with an analog-to-digital converter (ADC) and a microcontroller, with a weighing accuracy error of no more than ±10g. It can accurately acquire the weight data of tea leaves and transmit it to the payment control module in real time. The outer shell of the main unit 2 adopts an anti-interference shell to shield external electromagnetic interference and ensure the working stability of the internal modules.

[0019] The POS machine module 21 includes a password input unit, a farmer benefit card reading unit, a payment interface unit, and a printing unit. The farmer benefit card reading unit uses a contactless card reader, which supports reading the chip information and magnetic stripe information of the tea farmer benefit card to quickly obtain account information. The password input unit uses a privacy keypad, which supports password input and verification to prevent password leakage. The payment interface unit uses the AES-256 encryption algorithm and connects to the UnionPay unified payment interface and the rural payment integrated service platform to realize real-time transfer and encrypted transmission of transaction funds. The printing unit uses a thermal printer, which can quickly print transaction vouchers and traceability vouchers. A unique traceability code is printed on the voucher for easy retention and verification.

[0020] The traceability recording module includes an information code recognition component, an image acquisition component 23, a positioning unit, and an information input unit. The information code recognition component is a barcode scanner that can identify traceability marks on tea packaging and automatically acquire preliminary traceability information such as tea planting, processing, and storage. The image acquisition component 23 is a high-definition camera that can inspect tea, collect tea appearance characteristics, and assist in verifying tea varieties and grades. The positioning unit uses GPS and Beidou dual-mode positioning to acquire the geographical location information of the transaction location, with a positioning accuracy of no less than 10 meters. The information input unit is a touch input panel that allows manual input of tea farmer identity information (name, ID number), tea field location information (latitude and longitude, village and town address), tea variety information (such as Longjing, Pu'er, Tieguanyin), picking time, processing information, etc., generating a unique traceability code. The traceability code encoding complies with the provisions of GB / T 7027 and includes information such as product number, raw material number, tea farmer identification, and picking date. The traceability data complies with the technical requirements of GH / T1496-2025 Tea Product Traceability System.

[0021] The payment control module includes a unit price preset unit and an anomaly warning unit. The unit price preset unit can preset the corresponding unit price for various tea varieties and grades, supports manual adjustment of the unit price, and automatically synchronizes the adjusted unit price to the pricing system. The anomaly warning unit can issue warnings for abnormal weighing data (such as sudden weight changes) and abnormal transaction amounts (such as exceeding the normal range), reminding operators to verify the data. After receiving the weight data from the weighing module, the payment control module automatically calculates the amount payable (amount payable = weight × preset unit price), receives the Huinong Card account information and transaction password from the POS machine module 21, and links with the rural payment integrated service platform and UnionPay unified payment interface through the payment interface unit to complete password verification and fund transfer. At the same time, it binds the transaction information with traceability information and traceability code to generate integrated data.

[0022] The display module 22 adopts a high-definition touch screen, which displays the weight, unit price, amount due, last four digits of the agricultural benefit card account, transaction status (pending payment, in payment, payment successful, payment failed) and tea traceability information (traceability code, tea farmer information, tea field location, picking time, etc.) in real time. It supports touch operation, which makes it convenient for operators to adjust parameters and enter information.

[0023] The storage module uses an encrypted storage chip with a storage capacity of no less than 64GB. It is used to store tea weight data, transaction data (transaction amount, transaction time, information of both parties, and information of the agricultural benefit card account), tea traceability information, and integrated transaction-traceability data, which meet the data security requirements of GB / T22239 and GB / T35274. It supports daily automatic incremental backup and weekly automatic cold backup, and synchronizes data with the cloud traceability platform through RESTful APIs, enabling remote data query and management. It also supports offline storage, which can temporarily store data when the network is interrupted and automatically synchronize it to the storage module and the cloud traceability platform after the network is restored.

[0024] The workflow is as follows: 1) Preliminary preparation: Operators manually enter the tea source information through the information entry unit of the traceability record module, or scan the traceability mark on the tea packaging through the information code recognition component to obtain the preliminary traceability information; obtain the geographical location information of the transaction location through the positioning unit, and generate a unique traceability code after entering it into the system; and preset the corresponding unit price according to the tea variety and grade (such as first-level and second-level) through the unit price preset unit of the payment control module.

[0025] 2) Weighing and pricing: Place the tea to be traded on the weighing platform of the weighing module. The weighing module accurately obtains the weight data of the tea and transmits the weight data to the payment control module. The payment control module, in conjunction with the preset unit price, automatically calculates the amount payable and displays the tea weight, unit price, and amount payable through the display module 22.

[0026] 3) Payment Operation: The tea farmer brings the agricultural benefit card close to the agricultural benefit card reading unit of the POS machine module 21. The agricultural benefit card reading unit quickly reads the agricultural benefit card account information and displays it on the display module 22. The operator or tea farmer enters the transaction password through the password input unit. The payment control module verifies the transaction password. After successful verification, the control payment interface unit transfers the transaction amount directly from the transacting party's account to the tea farmer's agricultural benefit card through the UnionPay unified payment interface and the rural payment integrated service platform. If the password verification fails, the display module 22 prompts "Incorrect password, please re-enter" until the password verification is successful.

[0027] 4) Data Binding: After payment is completed, the payment control module immediately receives the payment success feedback information and binds the transaction information (transaction amount, transaction time, transaction party information, last four digits of the Huinong Card account) with the tea traceability information (traceability code, tea farmer information, tea field location, tea variety, and picking time) to generate integrated transaction-traceability data. This data is then synchronously stored in the storage module and uploaded to the cloud traceability platform to achieve data retention and synchronization.

[0028] 5) Voucher Output: The operator triggers the print command through the display module 22. The printing unit of the POS machine module 21 prints the transaction voucher and the traceability voucher. The transaction voucher includes information such as the transaction amount, transaction time, last three digits of the Huinong Card account, and transaction success indicator. The traceability voucher includes the traceability code, tea origin information, and transaction information. The tea farmer and the trading party each keep a copy, completing the entire tea transaction process. If the network is interrupted during the transaction, the system automatically enters offline mode, temporarily storing the transaction and traceability data. After the network is restored, it is automatically synchronized to the storage module and the cloud traceability platform to ensure that the data is not lost.

[0029] It should be noted that the specific embodiments of the present invention have been described in detail. For those skilled in the art, various obvious changes made to it without departing from the spirit and scope of the present invention are within the protection scope of the present invention.
