Description

Technical Field

[0001] This invention relates to the field of self-service vending equipment control technology, specifically to a method for precise dispensing control of a self-service wine dispenser based on mobile payment. Background Technology

[0002] With the popularization of mobile payment technology and the rapid development of the self-service vending industry, self-service wine dispensing machines are gradually being applied in various places such as restaurants, convenience stores, and outdoor settings, providing users with a convenient wine purchasing experience. Currently, the control methods of existing self-service wine dispensing machines still have many shortcomings: most devices can only dispense a single flavor of wine, failing to meet the taste needs of different users; the dispensing temperature is difficult to control, unable to adjust the liquid temperature according to user preferences, affecting the drinking experience; the dispensing accuracy is low, easily resulting in over- or under-dispensing, leading to a poor user experience; at the same time, existing devices often lack automatic capping and receipt printing functions after dispensing, posing risks of spillage and contamination, and failing to provide users with clear proof of purchase; furthermore, the payment verification security of some devices is insufficient, and there is a lack of a robust anomaly handling mechanism, resulting in a failure to respond promptly when the device malfunctions, affecting the normal operation of the device and the user experience.

[0003] In view of the shortcomings of the existing technology, there is an urgent need for a self-service wine dispensing machine control method that can realize multiple flavors in one machine, precise temperature control, quantitative wine dispensing, and integrate automatic receipt printing, automatic capping, secure payment and abnormal handling functions, so as to solve the shortcomings of the existing technology, improve the practicality, convenience and user experience of the self-service wine dispensing machine, and reduce the equipment operation and maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing self-service wine dispensing machine control methods, such as limited flavor options, low temperature control accuracy, inaccurate dispensing quantity, lack of post-dispensing processing functions, and inadequate anomaly handling. This invention provides a precise wine dispensing control method for self-service wine dispensing machines based on mobile payment, enabling one machine to switch between multiple flavors, automatically heat with controllable temperature, and dispense precise quantities. It also integrates automatic receipt printing, automatic capping, secure mobile payment, and comprehensive anomaly handling functions, thereby improving the user's wine purchasing experience and the stability of the equipment operation.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a method for precise dispensing control of a self-service wine dispensing machine based on mobile payment, specifically including the following steps:

[0006] S1. Trigger Startup: The user scans the unique identification QR code set on the body of the self-service wine dispenser through a mobile terminal to trigger the wine dispenser to start and enter the interactive state; the unique identification QR code is uniquely bound to the wine dispenser control module, and each wine dispenser corresponds to an independent QR code to avoid multiple devices triggering the machine by mistake.

[0007] S2. Mobile Payment and Parameter Setting: The dispensing machine control module generates an interactive interface that includes options for selecting the desired flavor, adjusting the dispensing quantity, and adjusting the dispensing temperature, and pushes this interface to the user's mobile terminal. After the user selects the desired flavor, sets the dispensing quantity and target temperature parameters, and completes the mobile payment, the payment platform sends a payment success signal to the dispensing machine control module. Mobile payment methods include at least one of WeChat Pay, Alipay, and UnionPay Quick Pay. Upon receiving the payment success signal, the control module encrypts and verifies the signal before proceeding with subsequent steps. If the payment fails or times out, the control module automatically cancels the order and sends a notification to the user's mobile terminal, re-entering the pending state. The dispensing machine has at least three built-in concentrated liquor storage units, each storing concentrated liquor of different flavors, providing users with diverse flavor options.

[0008] S3. Controllable Temperature Pre-processing: The control module activates the built-in heating component of the distiller based on the user-set target temperature parameters to automatically heat the base liquor. Simultaneously, a temperature sensor collects the base liquor temperature data in real time and feeds it back to the control module. The control module dynamically adjusts the power of the heating component to stabilize the base liquor temperature within the target temperature range. The heating component uses electromagnetic heating, with a temperature control range of 5℃-25℃ and a temperature control accuracy of ±0.3℃. The temperature sensor is a contact temperature sensor that collects base liquor temperature data in real time at a frequency of 1 time / second to ensure stable base liquor temperature and guarantee the drinking taste of the liquor.

[0009] S4. Automatic Flavoring Control: Based on the user's selected target flavor, the control module triggers the corresponding concentrated liquid storage unit to start. The corresponding concentrated liquid is then injected into the temperature-controlled base liquor at a preset ratio via a quantitative delivery component. Simultaneously, the stirring component is activated to uniformly stir the mixed liquor, completing the automatic flavoring process. The quantitative delivery component uses a micro-quantitative pump. The control module precisely controls the injection volume of the concentrated liquid by adjusting the pump's speed and operating time. The mixing ratio of the concentrated liquid to the base liquor can be adjusted within the range of 1:5 to 1:20 to suit different user taste preferences. The stirring component uses a silent stirring motor with a stirring speed of 500-800 r / min and a stirring time of 3-5 seconds, ensuring thorough mixing of the concentrated liquid and base liquor, with a uniformity deviation of no more than 5% after mixing.

[0010] S5. Precise Quantitative Dispensing: After flavoring, the control module activates the dispensing valve. Based on the set dispensing quantity parameters and the real-time dispensing flow data collected by the flow sensor in the dispensing pipeline, the opening of the dispensing valve is dynamically adjusted. When the actual total dispensing volume reaches the set quantity parameter, the control module immediately closes the dispensing valve to achieve precise dispensing. The flow sensor uses a high-precision turbine flow sensor with a flow acquisition accuracy of ±0.1ml. The control module integrates the real-time dispensing flow data to obtain the actual total dispensing volume. When the difference between the actual total dispensing volume and the set quantity parameter is less than 0.5ml, the control module gradually reduces the opening of the dispensing valve until it is completely closed to avoid excessive or insufficient dispensing. The dispensing quantity parameter can be continuously adjusted within the range of 50ml-1000ml with an adjustment accuracy of 1ml to meet different user needs for dispensing quantities.

[0011] S6. Post-dispensing processing: After the dispensing valve closes, the control module synchronously triggers the built-in printer to start, automatically printing a receipt containing the order number, payment amount, dispensing flavor, dispensing quantity, and dispensing time, and pushing it to the receipt outlet; simultaneously, the capping assembly is activated to automatically cap the container receiving the liquor. After capping, the capping assembly resets, and the control module pushes a dispensing completion notification to the user's mobile terminal; the printer is a thermal micro printer with a built-in replaceable thermal paper roll. When the remaining thermal paper is below a preset threshold, the printer sends a paper shortage signal to the control module, which simultaneously pushes a paper shortage notification to the backend management terminal and the dispensing machine's local display interface; the capping assembly adopts a pneumatic clamping structure, which can adapt to different sizes of liquor containers, and the capping pressure can be dynamically adjusted by the control module to ensure a sealed cap without damaging the container.

[0012] Furthermore, the present invention also includes an anomaly handling step: if the flow sensor, temperature sensor or concentrate delivery component malfunctions during the dispensing process, the control module immediately closes the dispensing valve, stops all operations, pushes a fault prompt to the user's mobile terminal, and pushes the fault information and fault location to the background management terminal. At the same time, the dispensing machine is locked until the fault is resolved and then unlocked to prevent the fault from escalating and to ensure the safety of the equipment and the user.

[0013] Furthermore, the control module adopts a PLC controller, which integrates data storage, signal processing, and instruction output functions. It can store at least 10,000 order data and equipment operation data, and supports remote querying, exporting, and parameter debugging on the background management terminal, which facilitates equipment operation and maintenance and data statistical analysis.

[0014] One or more technical solutions provided in this application embodiment have at least the following technical effects or advantages compared with the prior art:

[0015] 1. This invention integrates controllable temperature automatic heating and automatic flavoring functions. It achieves precise temperature control of the base liquor through an electromagnetic heating component. Combined with multiple independent concentrate storage units and quantitative delivery components, it enables one machine to switch between multiple flavors. Moreover, the mixing ratio of concentrate and base liquor is adjustable to suit the tastes and drinking temperature requirements of different users. It solves the defects of existing equipment such as single flavor and poor temperature control, and improves the drinking taste of the liquor.

[0016] 2. This invention employs a high-precision turbine flow sensor and a dynamic valve opening adjustment mechanism to achieve precise control of the dispensing quantity, resulting in high alcohol content and preventing excessive or insufficient dispensing. Furthermore, the dispensing quantity parameter can be continuously adjusted over a wide range to meet different dosage requirements of users and enhance their wine purchasing experience.

[0017] 3. This invention integrates automatic receipt printing and automatic capping functions. The receipt provides clear proof of purchase, while the automatic capping prevents spillage and contamination of the wine. It is compatible with different container sizes, further enhancing user convenience. At the same time, the printer has a paper shortage reminder function, which facilitates equipment maintenance.

[0018] 4. This invention adopts a multi-channel mobile payment method and has a payment signal encryption verification function to improve payment security; at the same time, it sets up a complete anomaly handling mechanism, which can respond in a timely manner, lock the device and push a notification when the device malfunctions, ensuring the stability of device operation and user safety, and reducing operation and maintenance costs.

[0019] 5. This invention uses a PLC controller as the control core, integrating data storage and remote debugging functions. It can store a large amount of order and equipment operation data, which facilitates back-end management and data analysis, improves equipment operation and maintenance efficiency, and adapts to the needs of large-scale deployment.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] like Figure 1-4 As shown, the self-service wine dispensing machine precise dispensing control method based on mobile payment described in this invention does not involve isolated steps, but rather forms a tight logical closed loop of "triggering and starting - parameter pre-setting - core dispensing - supporting protection - anomaly fallback". Each step is progressive, coordinated, and indispensable. The specific relationship is as follows (corresponding to the core technical features of the claims, the step relationships are clearly disclosed):

[0029] Triggering and Prerequisite Relationship: The S1 triggering and initiation step is the initial entry point of the entire control process. Through the unique binding of a dedicated identification QR code to the control module, it provides the basis for "independent response of a single device" for all subsequent steps, solving the problem of multiple devices triggering falsely. It is a prerequisite for starting S2 and subsequent steps. The S2 mobile payment and parameter setting step is the core prerequisite for process execution. It not only completes consumption confirmation through mobile payment, providing a compliance prerequisite for process advancement, but also clarifies the execution standards of the core wine dispensing steps S3-S5 through integrated parameter setting of taste, quantity, and temperature. At the same time, it completes the encrypted verification of payment signals to ensure consumption security. The result of its parameter setting directly determines the execution effect of subsequent steps.

[0030] The core collaborative relationship in wine production: The three steps of S3 temperature-controlled pretreatment, S4 automatic flavoring, and S5 precise quantitative wine production constitute the core execution links of the entire control method. These three steps are sequentially connected and mutually supportive, forming the core link of "base wine pretreatment - flavor blending - precise output": S3 provides S4 with base wine at a suitable temperature, ensuring the uniformity of mixing between the concentrate and the base wine and avoiding flavoring deviations caused by improper temperature; S4 provides S5 with mixed wine that meets the user's taste, breaking the limitation of existing equipment with a single flavor; S5, based on the processing results of the first two steps, achieves precise quantitative output, ensuring that the total output is consistent with the user's settings. The three work together to fulfill the core requirements of "precise, diverse, and palatable" wine production.

[0031] Supporting and backup functions: The S6 post-dispensing processing step is a complementary step to the core dispensing process, addressing issues such as post-dispensing receipts and wine preservation. It seamlessly integrates with S5 to enhance the user experience. The anomaly handling step runs through all core stages from S3 to S5, monitoring the operational status of each component in real time. It serves as a backup to prevent escalation of faults and ensure the safety of equipment and users. The control module (PLC controller) acts as the central coordinator, running through all steps. It receives feedback signals from each component and outputs precise control commands, ensuring the coordinated operation of S1-S6 and the anomaly handling step. This achieves fully automated control of the entire process, forming a complete logical system of "trigger-pre-processing-core-supporting-backup".

[0032] In this implementation scheme, the core key points of the implementation of each method step of the present invention are "precise collaboration, strong adaptability, and convenient operation and maintenance". The implementation details and mutual cooperation of each step directly determine the overall control effect. The specific implementation points are as follows:

[0033] Key points for coordinated implementation of steps: The timing and parameters of each step must be precisely matched. For example, the temperature control accuracy (±0.3℃) of S3 must be coordinated with the stirring parameters (500-800r / min, 3-5 seconds) and mixing ratio (1:5 to 1:20) of S4. In this embodiment, the combination of 15℃ base liquor, 600r / min stirring speed, and 1:10 mixing ratio can make the concentrate dissolve quickly and avoid uneven flavoring. The flow rate acquisition frequency (1 time / second) of S5 must be synchronized with the opening speed adjustment of the dispensing valve to ensure that the valve is gradually closed when the difference between the actual dispensing volume and the set value is less than 0.5ml, thus avoiding deviation in alcohol content. The parameter setting range of S2 (quantity 50-1000ml, temperature 5-25℃) must be precisely matched with the execution range of S3-S5 to ensure that the parameters set by the user can be implemented without invalid settings.

[0034] Key points for equipment adaptation and implementation: The execution of each step depends on the precise linkage between the corresponding components and the control module. For example, in the S4 automatic seasoning step, the rotation speed and working time of the quantitative delivery component (micro quantitative pump) must correspond precisely to the flavor parameters received by the control module to avoid deviations in the amount of concentrate injected; in the S6 automatic capping step, the pressure adjustment of the pneumatic clamping capping component must be adapted to the container specifications, and the control module must dynamically adjust the pressure according to the container detection signal to ensure that the cap is sealed and does not damage the container; the printer's paper shortage detection and the signal feedback from each sensor must be transmitted to the control module in real time to ensure that the steps are connected without any interruptions.

[0035] Key points for convenient operation and maintenance: The step design takes into account the convenience of operation and maintenance. For example, the paper shortage prompt of the printer in S6 and the fault location push of the abnormal handling steps are all linked with the back-end management terminal. Staff can obtain the equipment status without on-site inspection, quickly replenish consumables and troubleshoot; the order data storage and remote debugging functions of the control module can realize centralized operation and maintenance of multiple devices, adapt to the needs of large-scale deployment, and reduce operation and maintenance costs.

[0036] Specifically, each step of the method in this invention plays a targeted role, synergistically addressing all defects. The specific functions and benefits of each step are as follows:

[0037] 1. S1 Trigger Startup Procedure: Addressing the issues of inconsistent triggering methods and accidental triggering by multiple devices in existing systems, this design utilizes a unique QR code binding to the control module. This ensures independent response for each device, with each dispensing machine corresponding to a unique QR code, preventing accidental device activation due to incorrect scanning by the user. Its purpose is to provide a precise and convenient triggering method, laying the foundation for subsequent steps. The benefits include improved accuracy in device triggering, preventing equipment damage and user inconvenience caused by accidental triggering, and simplifying user operation, requiring only a single scan to start the device, thus enhancing the initial user experience.

[0038] 2. S2 Mobile Payment and Parameter Setting Steps: Addressing the issues of insufficient payment verification security, limited parameter settings, and lack of diverse flavor options in existing devices, this step resolves payment security risks and prevents payment information leakage and process chaos after payment failure by utilizing "multi-channel payment via WeChat, Alipay, and UnionPay" + "encrypted payment signal verification." It also addresses the limitation of limited flavor options in existing devices through "integrated parameter settings for flavor, quantity, and temperature," combined with at least three independent concentrate storage units. Its function is to complete consumption confirmation, clarify the execution standards for subsequent steps, and ensure payment security. Its benefits include improved payment security and flexibility, meeting the personalized needs of different users (flavor, quantity, temperature), and providing precise parameter basis for subsequent core brewing steps, ensuring that the brewed product meets user expectations.

[0039] 3. S3 Controllable Temperature Pretreatment Step: Addressing the issue of uncontrollable liquor temperature in existing equipment, which affects the drinking experience, this step achieves precise temperature control of the base liquor (temperature range 5℃-25℃, accuracy ±0.3℃) through the linkage of electromagnetic heating components, contact temperature sensors, and a control module. Real-time temperature feedback dynamically adjusts the heating power to ensure stable base liquor temperature. Its function is to provide temperature-appropriate base liquor for subsequent automatic flavoring, ensuring uniform flavoring and improved taste. Its advantage lies in overcoming the low temperature control accuracy of existing equipment, allowing the liquor temperature to match user preferences, and avoiding uneven dissolution of the concentrate and poor flavoring effects caused by excessively high or low temperatures. This lays the foundation for uniform flavoring and improves the drinking experience.

[0040] 4. S4 Automatic Flavoring Step: Addressing the issue that existing equipment can only produce a single flavor and cannot meet the diverse taste preferences of users, this step utilizes the synergy of multiple independent concentrate storage units + quantitative delivery components + stirring components to achieve multi-flavor switching within a single machine. The mixing ratio of concentrate to base liquor can be adjusted within the range of 1:5 to 1:20, and the stirring component ensures uniform mixing (uniformity deviation not exceeding 5%). Its function is to achieve diversified flavor blending and ensure consistent taste. Its advantage lies in breaking the limitation of existing equipment to a single flavor, adapting to different user taste preferences, and avoiding the proportioning deviations and uneven mixing problems of manual flavoring through quantitative delivery and uniform stirring. This improves flavoring accuracy and consistency of liquor taste, completing flavoring without manual intervention and enhancing the automation level of the equipment.

[0041] 5. S5 Precise Quantitative Dispensing Step: Addressing the issues of low dispensing accuracy and the tendency for over- or under-dispensing in existing equipment, this step utilizes a high-precision turbine flow sensor (accuracy ±0.1ml) to collect flow data in real time. The control module integrates and calculates the actual total dispensing volume, combined with a mechanism of gradually closing the valve when the difference is less than 0.5ml, achieving precise dispensing. Furthermore, the dispensing volume can be continuously adjusted within the range of 50ml-1000ml (accuracy 1ml). Its purpose is to ensure that the total dispensing volume matches the user-set parameters, avoiding waste and protecting user interests; its benefit lies in resolving the core deficiency of insufficient dispensing accuracy in existing equipment.

[0042] To further clarify the practical application adaptability of the present invention, and in conjunction with the specific embodiments described above, and in combination with existing technologies and devices such as self-service vending equipment, catering support devices, and outdoor service equipment, the following describes in detail the specific application methods of the present invention under different usage scenarios, the usage status of each structure, and the effective connection and installation linkage details with existing technologies and devices.

It does not require the construction of complex supporting facilities, can be quickly deployed and flexibly moved, and meets the self-service wine purchase needs of outdoor users.

[0051] The main body of the dispensing machine of this invention is mounted on a movable bracket, with casters at the bottom for easy and flexible movement. It can be fixed next to an existing mobile vending vehicle or inside an outdoor rain shelter. The control module 1 is connected to existing mobile power supply equipment (generator, mobile power bank set) via a power cord and is fixed with a waterproof plug to prevent outdoor rainwater erosion and ensure stable power supply. An existing outdoor rain cover is installed on the outside of the dispensing machine, which is linked with the rain shelter to prevent rainwater from wetting the equipment and contaminating the wine.
