Description

Technical Field

[0001] This invention relates to the technical field of product display and sales, specifically to a display-style sales cabinet system and its control method. Background Technology

[0002] Display-style vending machines, as a type of retail terminal equipment that integrates product display and sales functions, are widely used in shopping malls, supermarkets, exhibitions, and other venues. With the rapid development of new retail and unmanned retail models, self-service vending machines are widely used in office buildings, communities, subway stations, factories, and campuses due to their advantages such as 24-hour operation, small footprint, and low operating costs. Traditional vending machines mainly rely on mechanical buttons, coin-operated payment, or simple QR code payment to complete transactions. The overall structure typically includes the cabinet, product channels, locking devices, and a basic control motherboard. However, existing vending machines still have the following shortcomings in practical applications: limited identification methods, lack of consumer tasting experience, poor interactive experience, and insufficient equipment status monitoring capabilities; some machines also have weak anti-theft and anti-vandalism designs, posing a high risk to asset security; they consume a large amount of electricity during long-term operation, which is inconsistent with the trend of green and low-carbon development; furthermore, most existing vending machines only have simple display or sales functions, making it difficult to achieve a closed-loop service from product display and tasting experience to immediate purchase; and the tasting delivery methods are simplistic, lacking precision and controllability. Existing tasting devices mostly use fixed open placement or simple mechanical dispensing methods, failing to accurately deliver products according to the actual needs of potential customers. The current system suffers from several drawbacks. Firstly, it lacks precise control over the release of samples, leading to potential waste. Secondly, the sales channels are limited, with a lack of online-offline integration. Existing sales counters typically only support on-site purchases, making it difficult to guide potential customers to online stores or other physical locations when inventory is low or when they wish to access more product information. This restricts the reach and flexibility of the sales service. Thirdly, the human-computer interaction capabilities are limited, lacking intelligent perception and response to customer behavior. Most existing devices rely on user-initiated actions (such as button selection) for interaction, lacking the ability to proactively perceive customer approach, gaze, and verbal descriptions. This prevents the system from dynamically adjusting the displayed content and push strategies based on real-time customer behavior.

[0003] Therefore, in order to address the shortcomings of existing technologies, it is necessary to develop a sales display system and its operation method, which has significant technical value and broad market prospects. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing sales counters, such as their limited sales methods, lack of consumer tasting opportunities, poor interactive experience, high power consumption during long-term operation, and incompatibility with green and low-carbon development trends. This invention addresses these issues by designing a display-style sales counter system that incorporates a cabinet frame, cabinet panels, shelves, a data collector, a controller, a display, a battery, and a tasting mechanism. The controller is equipped with a control system that includes tasting modules, current order modules, external order modules, a self-learning module, a drive control module, a signal acquisition module, and a central processing module, along with corresponding control methods. This system enables intelligent control, environmental adaptability, strong perception, and smooth adjustment for sales and tasting.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A sales display system includes a cabinet frame, cabinet panels, shelves, a collector, a controller, a display, a battery, and a tasting mechanism. The shelves, collector, controller, display, battery, and tasting mechanism are mounted on the cabinet frame. The cabinet panels cooperate with the cabinet frame to form the entire cabinet. The shelves are located at the lower part of the cabinet frame, and the tasting mechanism is located at the upper part of the cabinet frame. The power supply terminal of the controller is electrically connected to the power supply terminal of the battery, and the control terminal of the controller is electrically connected to the control terminals of the collector, the display, the tasting mechanism, and the shelves. The controller is equipped with a control system, which includes a tasting module, a current order module, and an external order module. The tasting module controls the tasting facility to push tasting items to interested customers. The current order module controls the display of order links and the push of order items to interested customers. The external order module controls the display of nearby offline or online stores after recognizing the current order module, and pushes the corresponding order links to interested customers so that they can place orders in a timely manner. The display shows the order links from the current order module and the external order module.

[0006] Furthermore, the cabinet frame is made of metal.

[0007] Furthermore, the cabinet panel is selected from metal, plastic, or glass materials.

[0008] Furthermore, the cabinet panels are preferably made of transparent plastic, such as PMMA or PC. Transparent plastic is lightweight and allows viewers to see the products inside.

[0009] Furthermore, the cabinet panel includes a front door panel and peripheral door panels. The peripheral door panels are installed on the top, bottom, and three sides of the cabinet frame.

[0010] Furthermore, the lower door panel is rotatably connected to the cabinet frame via a rotating shaft, which includes a movable shaft and a fixed shaft. The fixed shaft is mounted on the cabinet frame, and the movable shaft is rotatably connected to the fixed shaft. The lower door panel is equipped with the movable shaft. A small motor is mounted on the fixed shaft, and the drive end of the small motor is connected to the movable shaft. The control end of the small motor is electrically connected to the control end of the controller. The small motor is selected as a forward and reverse rotating small motor, and a reducer is provided on the small motor.

A small motor is used to automatically open or close the lower door panel. The lower door panel is a double-opening type, and each lower door panel is equipped with at least one small motor. A concealed electromagnetic handle is installed on the lower door panel. One end of the electromagnetic handle is connected to the lower door panel via a pivot, and the other end is connected to the lower door panel via electromagnetic attraction. An electromagnet is installed on the lower door panel, and the control end of the electromagnet is electrically connected to the control end of the controller. The handle surface is made of iron, which can magnetically attract the electromagnet. When the electromagnetic handle needs to be opened, the controller cuts off the power, allowing it to be used; when it does not need to be opened, the controller turns on the power. This type of electromagnetic handle consumes almost no power. This electromagnetic handle is generally operated by the administrator, and other users are restricted from using it.

[0011] Furthermore, the tasting mechanism includes a tasting table, a gate actuator, an S-shaped pipe, and a tasting container. The tasting container is located at the top of the cabinet, and the gate actuator is located at the bottom of the tasting container. The gate actuator is mounted on the cabinet, and its control terminal is electrically connected to the control terminal of the controller.

The storage cavities are interconnected with the inner cavities of the S-shaped pipes, and a switch gate is located at the contact point between the storage cavity and the inner cavity of the S-shaped pipe. The switch gate can be opened at different positions using a gate-opening actuator, such as gradually opening from a small gap to fully opening and then gradually closing completely. Each inclined section of the S-shaped pipe has an angle between 45° and 60° with the horizontal plane to facilitate the smooth sliding of the tasting items onto the tasting platform.

[0014] Furthermore, the gate opening actuator includes a gate opening telescopic electric cylinder, a gate slide groove, and a switch gate.

[0015] Furthermore, the data collector includes a radar collector, a visual collector, a sound collector, and a barcode scanner. These collectors are respectively mounted on the cabinet frame. The control terminals of each collector are electrically connected to the control terminal of the controller. The radar collector detects whether a potential customer is near the sales counter and sends the detection signal to the controller to turn the display on or off. The visual collector detects nearby potential customers and sends the detection signal to the controller to control the continuous display, online display of items, and display of order links on the display. The sound collector detects potential customers' verbal descriptions of items and captures their preferred descriptions, sending the detection signal to the controller to display the item on the display; multiple items can be displayed. The barcode scanner detects the order link signal from the visual collector and / or the preferred item signal from the sound collector, sending the signal to the controller to display a QR code for ordering on the display.

[0016] Furthermore, the control system is also equipped with a self-learning module, a drive control module, a signal acquisition module, and a central processing module. The self-learning end of the central processing module is electrically connected to the self-learning end of the self-learning module, the drive end of the central processing module is electrically connected to the drive end of the drive control module, the control end of the drive control module is electrically connected to the control end of the tasting mechanism and the control end of the container, the acquisition end of the central processing module is electrically connected to the acquisition signal end of the signal acquisition module, and the display end of the central processing module is electrically connected to the display end of the monitor.

[0017] Furthermore, the self-learning module is equipped with a convolutional neural network model, a recurrent neural network model, a deep reinforcement learning convolutional network model, a memory-enhanced network model, and a graph neural network model. The signal acquisition module transmits the acquired signals to the convolutional neural network model for feature vector processing through the central processing module. The convolutional neural network model then transmits the signals to the recurrent neural network model for context feature vector processing. Finally, the signals are processed by the deep reinforcement learning convolutional network model, which has a memory-enhanced network model and a graph neural network model working together, before being sent to the central processing module.

[0018] Furthermore, the signal acquisition module includes a radar acquisition module, a visual acquisition module, a sound acquisition module, and a barcode acquisition module.

[0020] Furthermore, a reciprocating electric cylinder is provided on the inner end of the holder. The control end of the reciprocating electric cylinder is connected to the control end of the controller. A push plate is installed on the drive end of the reciprocating electric cylinder. The reciprocating electric cylinder is used to drive the push plate to push the items on the holder out so that the user can easily take them out.

[0021] Furthermore, an infrared sensor is provided on the outer end of the storage unit. The control terminal of the infrared sensor is electrically connected to the control terminal of the controller. The infrared sensor is used to collect whether there are goods on the storage unit and to collect the quantity of goods passing through. If there are no goods, a no-goods signal is collected and fed back to the controller, and then sent to the administrator via wireless signal to notify them to replenish the stock.

[0022] Furthermore, the storage unit is equipped with multiple storage units, each of which is equipped with a reciprocating electric cylinder, a pusher plate, and an infrared sensor. The reciprocating electric cylinder can push a corresponding number of items based on the quantity ordered.

[0023] Furthermore, the end of the storage unit is equipped with an inclined conveying pipe. The high point of the inclined conveying pipe connects to the end of the storage unit, and the low point connects to a retrieval platform. The retrieval platform is mounted on the cabinet frame and is located inside the lower door panel. When the reciprocating electric cylinder pushes the goods, the lower door panel opens simultaneously. If the goods slide onto the retrieval platform, the lower door panel opens fully, allowing the buyer to take their items. After the buyer has taken their items, the lower door panel automatically closes. The lower door panel can be opened individually or both at the same time. A weight sensor is installed on the retrieval platform, and the control terminal of the weight sensor is electrically connected to the control terminal of the controller. When there are no goods, the weight sensor sends a signal to the controller, which then controls the lower door panel to close.

[0024] Furthermore, the radar data acquisition device is selected as a lidar data acquisition device.

[0025] Furthermore, the radar data acquisition device selected is the TFmini Plus model. To enable the radar data acquisition device to scan within a 180° range, it can be mounted on a servo motor, with the servo motor's control terminal connected to the controller's control terminal.

[0032] Beneficial effects This invention designs a sales cabinet system that integrates a display rack, cabinet panels, shelves, a data collector, a controller, a display, a battery, and a tasting mechanism. The controller is equipped with a control system that includes tasting, order placement, and external order placement modules, as well as a self-learning module, drive control module, signal acquisition module, and central processing module, along with corresponding control methods. This enables intelligent control, environmental adaptability, strong perception, and smooth, precise adjustment for sales and tasting. By integrating the shelves, tasting mechanism, and order placement module into a single cabinet, this invention constructs a complete service chain of "display, tasting, and immediate purchase." Potential customers can place orders directly through the order placement module after tasting, and the shelves immediately push the corresponding items, eliminating the need to find other purchasing channels, effectively shortening the purchase decision path and significantly improving purchase conversion efficiency. Simultaneously, the S-shaped pipeline design ensures that the tasting items follow a winding path during transport, effectively slowing down the descent and preventing damage from direct falls, thus ensuring the integrity and hygiene of the tasting items. This invention achieves precise control over the release of tasting items through the cooperation of a gate-opening actuator (including a gate-opening telescopic electric cylinder, a gate slide groove, and a switching gate) and an S-shaped pipe. Tasting items are released in a measured quantity only after a potential customer expresses their intention to try them, avoiding the problems of indiscriminate use or excessive consumption of items in traditional open-style tasting methods. The tasting module pushes items on demand based on signals collected by the collector, avoiding resource waste caused by blindly releasing tasting items and reducing the tasting costs for merchants. This invention achieves an organic integration of on-site purchases and online / offline store purchases through the coordinated operation of the in-store and out-of-store modules. When on-site inventory is insufficient or potential customers wish to obtain a wider selection of products, the out-of-store module can automatically identify the status of the in-store module and then redirect to display purchase links for the nearest offline or online store, allowing potential customers to complete cross-channel purchases without changing their shopping environment. This design breaks the physical inventory limitations of traditional sales counters, expanding the sales service scope from a single counter to the entire retail network, greatly improving the coverage and flexibility of sales services. This invention achieves multi-dimensional intelligent perception of potential customers' behavior through multimodal collaboration of radar, vision, sound, and QR code scanning. The radar sensor detects whether a potential customer is approaching and automatically wakes the display; the vision sensor identifies nearby potential customers and continuously displays products and order links; the sound sensor captures the potential customer's verbal descriptions of items and displays related items accordingly; and the QR code scanning quickly responds to order requests and generates payment QR codes. This multimodal proactive perception mechanism significantly lowers the operational threshold for potential customers and improves the naturalness and fluency of the interaction. The invention incorporates a collaborative architecture of convolutional neural network, recurrent neural network, deep reinforcement learning convolutional network, memory-enhanced network, and graph neural network models in the control system, enabling multi-level feature extraction, contextual understanding, and intelligent decision-making from the collected potential customer behavior signals.By combining deep reinforcement learning with memory enhancement networks, the system can continuously learn the preference patterns of potential users, constantly optimize the accuracy of taste test recommendations and product recommendations, and achieve a self-evolving service experience that becomes smarter with use.

Detailed Implementation

[0039] 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.

[0040] See Figure 1 and Figure 2As shown in the illustration, this invention provides a sales display system without refrigeration. The system includes a frame 01, a cabinet panel, a shelf 02, a collector, a controller 05, a display, a battery, and a tasting mechanism 03. The shelf 01 is equipped with the shelf 02, collector, controller 05, display, battery, and tasting mechanism 03. The shelf panel and frame 01 cooperate to form the entire cabinet.

The control terminals of the controller 05 are electrically connected to the control terminals of the collector, the display, the tasting mechanism 03, and the shelf 02, respectively. The controller is equipped with a control system, which is mounted on... There are three modules: a tasting module, a pre-order module, and an external order module. The tasting module controls the tasting organization to push tasting items to potential customers. The pre-order module controls the display of order links and the push of order items to potential customers via the device 02. The external order module controls the display of nearby offline or online stores after recognizing the pre-order module, and pushes the corresponding order links to potential customers so that they can purchase and place orders in a timely manner. The display is used to show the order links from the pre-order module and the external order module. The display includes an upper display 04 and a lower display 06. The upper display 04 and the lower display 06 can synchronously display products, advertisements, order links, tasting prompts, or successful orders, or they can asynchronously display products, advertisements, order links, tasting prompts, or successful orders. Furthermore, the display on the upper monitor (04) and the lower monitor (06) is switched according to the height of the people. If the visual acquisition device detects that the target person is relatively short, the lower monitor will display the promotional and operation interface, while the upper monitor will serve as an auxiliary display. If the visual acquisition device detects that the target person is relatively tall, the upper monitor will display the promotional and operation interface, while the lower monitor will serve as an auxiliary display. This is to meet people's usage needs. Here, the visual acquisition device and visual acquisition module identify the height of the people and then feed the feedback to the controller, which in turn controls the corresponding monitor.

The cavity includes several tasting chambers, the same number as the number of S-shaped pipes, with at least one of each type selected. The rotating cover can be opened by the taster for tasting and rotated back to its original position after tasting to prevent prolonged exposure of the tasting items and to avoid mutual interference between items, which could alter the taste. The tasting item storage box is made of transparent material and has a storage cavity inside. The number of storage cavities is the same as the number of S-shaped pipes, and at least one of each is selected. The storage cavities and the inner cavities of the S-shaped pipes are interconnected, and a switch gate is provided at the contact point between the storage cavities and the inner cavities of the S-shaped pipes. The switch gate can be opened at different positions by a gate-opening actuator, such as gradually opening from a small gap to fully opening and then gradually closing completely. The gate-opening actuator includes a gate-opening telescopic electric cylinder, a gate slide groove, and a switch gate. The gate-opening telescopic electric cylinder is installed on the cabinet frame, and the gate slide groove is installed on the cabinet frame. The control end of the gate-opening telescopic electric cylinder is electrically connected to the control end of the controller, and the drive end of the gate-opening telescopic electric cylinder is connected to the switch gate. The switch gate is slidably connected to the gate slide groove. The gate-opening telescopic electric cylinder, the gate slide groove, and the switch gate are all located at the bottom of the tasting container. The switch gate is used to open and close the S-shaped pipes.

[0044] The data acquisition system includes a radar collector, a visual collector, a sound collector 10, and a barcode scanner 08. These three devices are mounted on the display rack. Their control terminals are electrically connected to the control terminal of a controller. The radar collector detects whether potential customers are near the sales counter and sends the signal to the controller to turn the display on or off. The visual collector detects nearby potential customers and sends the signal to the controller to control the continuous display, online item display, and order link display. The sound collector detects potential customers' verbal descriptions of the items and identifies their preferences. The system uses a visual sensor to collect signals from the visual sensor and / or an audio sensor to collect signals indicating the user's preferred item. It then sends these signals to the controller to display a QR code for ordering. The signal acquisition module includes a radar acquisition module, a visual acquisition module, an audio acquisition module, and a QR code acquisition module. These modules are integrated into the control system. The radar acquisition module is electrically connected to the radar sensor, the visual acquisition module to the visual sensor, the audio acquisition module to the audio sensor, and the QR code acquisition module to the QR code acquisition module. Furthermore, if the system detects a repeat tasting attempt by the same user, it sends a signal back to the controller, which then closes the gate opening mechanism, preventing the tasting from restarting and instead pushing an order link. If the system detects a different user, it reopens the tasting mode, activates the gate opening mechanism, and releases the tasting item onto the tasting table.

[0045] The control system also includes a self-learning module, a drive control module, a signal acquisition module, and a central processing module. The self-learning end of the central processing module is electrically connected to the self-learning end of the self-learning module, the drive end of the central processing module is electrically connected to the drive end of the drive control module, the control end of the drive control module is electrically connected to the control end of the tasting mechanism and the control end of the placement device, the acquisition end of the central processing module is electrically connected to the acquisition signal end of the signal acquisition module, and the display end of the central processing module is electrically connected to the display end of the monitor. The self-learning module is equipped with a convolutional neural network model, a recurrent neural network model, a deep reinforcement learning convolutional network model, a memory enhancement network model, and a graph neural network model. The signal acquisition module transmits the acquired signals to the convolutional neural network model for feature vector processing through the central processing module. The convolutional neural network model then transmits the signals to the recurrent neural network model for context feature vector processing. Finally, the signals are processed by the deep reinforcement learning convolutional network model, which has a memory enhancement network model and a graph neural network model working together, before being sent to the central processing module.

[0046] The storage unit is a multi-layered unit, with each layer arranged in parallel. The unit is made of metal or plastic. A reciprocating electric cylinder is located at the inner end of the unit, and its control end is connected to the control end of the controller. A pusher plate 32 is installed on the drive end of the reciprocating electric cylinder 31. The reciprocating electric cylinder drives the pusher plate to push items out of the unit for easy access by the user. An infrared sensor is located at the outer end of the unit, and its control end is electrically connected to the control end of the controller. The infrared sensor is used to detect the presence and quantity of goods on the unit. If no goods are present, a no-goods signal is received and fed back to the controller, which then sends a wireless signal to the administrator for restocking notifications. The unit has multiple storage units, each equipped with a reciprocating electric cylinder, a pusher plate, and an infrared sensor. Based on the quantity of the ordered item, a reciprocating electric cylinder pushes the corresponding number of items. An inclined conveyor pipe is located at the end of the shelf, with its high point connected to the end of the shelf and its low point connected to a retrieval platform. The retrieval platform is mounted on the shelf and located inside the lower door panel. When the reciprocating electric cylinder pushes the items, the lower door panel opens simultaneously. If an item slides onto the retrieval platform, the lower door panel opens fully, allowing the customer to retrieve their item. After retrieval, the lower door panel automatically closes. The lower door panel can open individually or both doors simultaneously. A weight sensor is located on the retrieval platform, and its control terminal is electrically connected to the controller's control terminal. When there are no items, the weight sensor sends a signal to the controller, which then controls the lower door panel to close.

[0047] The system includes a millimeter-level radar acquisition module, a TFminiPlus radar acquisition unit (which can be mounted on a servo motor to achieve 180° scanning range), and a vision acquisition unit (ESP32CAM). It also features an INMP441 sound acquisition unit with a MEMS sound sensor. A touchscreen display is used for displaying product advertisements. A battery is installed at the bottom of the cabinet. The sales cabinet can also be powered externally, either by the battery or other components. A refrigeration system, including a refrigeration unit, temperature sensors, and refrigeration pipes, is located at the bottom of the cabinet. The temperature sensors, located on the tasting containers and shelves, collect temperatures and feed them back to the controller to adjust the refrigeration unit's settings. The refrigeration unit operates by connecting the sample storage boxes and containers of the tasting facility via refrigeration pipes. It cools and refrigerates these boxes and containers, similar to a refrigerator. The sample storage boxes can be equipped with a refrigeration insulation layer, and the lids are sealed to the box body for insulation. The lower compartment of the cabinet storing the containers also uses a refrigeration insulation layer, and the lower door panel has a sealing ring for effective insulation. The cabinet shelves, cabinet panels, and sample containers... All storage boxes are made of metal. This is an example of a refrigerated sales cabinet. A refrigerated sales cabinet is based on a non-refrigerated sales cabinet with the addition of a refrigeration system and corresponding components to achieve heat preservation and refrigeration functions. The cabinet frame also has a heating system, including an upper heater (such as a heating resistance wire) and a lower heater (such as a heating resistance wire). The control terminals of the upper and lower heaters are respectively connected to the control terminal of the controller. The upper heater is located inside the tasting container and is used to heat the tasting container. The lower heater is located inside the container and is used to heat the container. The aforementioned temperature sensors are used to collect the temperature of the tasting container and the container, and then feed it back to the controller to control whether to heat up. In other words, the temperature sensors collect the temperature of the tasting container and the container. Each item has a suitable temperature range for consumption. If the temperature collected by the temperature sensor exceeds the suitable temperature range for consumption, the item is cooled down; if the temperature collected by the temperature sensor is below the suitable temperature range for consumption, the item is heated up. In addition, there is also an example of a sales cabinet without refrigeration.

[0048] The shelf is equipped with a fragrance device, including a fragrance heater and a fragrance box. The fragrance box contains fragrance agents for the items being sold, such as those that emit a milky scent, to attract customers. The fragrance box is attached to the fragrance heater, whose control terminal is connected to the controller. When the visual sensor detects a potential customer, it sends a signal to the controller, which then controls the fragrance heater to heat up, causing the fragrance agent in the fragrance box to release its fragrance and attract the customer to place an order. If the visual sensor does not detect a potential customer, the controller will not control the fragrance heater. In this case, the fragrance agent in the fragrance box will evaporate in minimal amounts, allowing the fragrance to last longer, similar to a heated car air freshener.

[0049] One method for operating a display-style sales counter system includes the following steps: Step 1: Building the System Framework The exhibition-style sales cabinet system includes a cabinet frame, cabinet panels, shelves, collectors, controllers, displays, batteries, and tasting mechanisms.

Step 5: Matching the data collector Based on step 4, the data collector includes a radar collector, a visual collector, a sound collector, and a barcode scanner. These collectors are installed on the display shelf. The control terminals of each collector are electrically connected to the control terminal of the controller. The radar collector detects whether a potential customer is near the sales counter and sends the signal to the controller to turn the display on or off. The visual collector detects nearby potential customers and sends the signal to the controller to control the continuous display, online item display, and order link display. The sound collector detects potential customers' verbal descriptions of items and identifies their preferred items, sending the signal to the controller to display those items. Several items can be displayed.

Step 6: Matching the Control System Based on step 5, the controller is equipped with a control system, which includes a tasting module, a current order module, and an external order module. The tasting module is used to control the tasting facility to push tasting items to potential customers. The current order module is used to control the display of order links and the control of the device to push order items to potential customers. The external order module is used to control the display of nearby offline or online stores after recognizing the current order module, and push the corresponding order links to potential customers so that they can purchase and place orders in a timely manner. The display is used to show the order links of the current order module and the external order module. The control system is equipped with a self-learning module, a drive control module, a signal acquisition module, and a central processing module. The self-learning end of the central processing module is electrically connected to the self-learning end of the self-learning module. The drive end of the central processing module is electrically connected to the drive end of the drive control module. The control end of the drive control module is electrically connected to the control end of the tasting mechanism and the control end of the container, respectively. The acquisition end of the central processing module is electrically connected to the acquisition signal end of the signal acquisition module. The display end of the central processing module is electrically connected to the display end of the monitor. The self-learning module is equipped with a convolutional neural network model, a recurrent neural network model, a deep reinforcement learning convolutional network model, a memory-enhanced network model, and a graph neural network model.

[0050] Specifically: The sales display system is a stand-up cabinet structure with three shelves at the bottom; a touch screen display is embedded in the upper front of the cabinet, with a LiDAR and visual sensor installed above it, and a sound and barcode scanner installed below it; a controller with a built-in operating system is installed inside the cabinet; the upper door panel is hinged to the cabinet and equipped with a lock for daily maintenance of the tasting area, and the upper door panel has corresponding displays, LiDAR and visual sensors. The cabinet includes a recess for a sound collector, a barcode scanner, and a controller. The lower door panel has a split design, with one panel on each side. Each lower door panel is rotatably connected to the cabinet frame via a pivot shaft, which includes a moving shaft 51 and a fixed shaft 53. The fixed shaft is mounted on the cabinet frame, and the moving shaft is rotatably connected to the fixed shaft. The lower door panel is mounted on the moving shaft. A small forward / reverse motor 52 is mounted on the fixed shaft, and the small motor has a reducer. The drive end of the small motor is connected to the moving shaft, and the control end of the small motor is electrically connected to the control end of the controller. Each lower door panel also has a concealed electromagnetic handle. The tasting container is made of transparent PMMA and has four internal storage chambers for storing four different tasting items. Each chamber has an S-shaped pipe at the bottom, with one end connected to the inner cavity and the other to the tasting platform. The tasting platform, fixed baffle, and rotating baffle together form four independent tasting chambers, each corresponding to an outlet of the S-shaped pipe. Each of the four chambers is equipped with an independent gate-opening actuator. Furthermore, a miniature vibrator is located in the middle of the S-shaped pipe. The control end of this vibrator is electrically connected to the control end of the controller. After the tasting, the controller activates the miniature vibrator to vibrate any remaining food residue from the S-shaped pipe onto the tasting platform, facilitating subsequent cleaning by the administrator. The storage unit consists of three parallel metal shelves, each with multiple storage units, each for holding one type of product. A reciprocating electric cylinder is installed at the inner end of each storage unit (near the rear wall of the shelf), and an infrared sensor is installed at the outer end of each storage unit (near the lower door panel). An inclined conveyor pipe is connected to the end of each shelf (near the lower door panel). The system includes: a lidar sensor to detect if a potential customer is near the sales counter (detection distance set at 5 meters); a signal to the controller when a customer enters within 5 meters; the controller wakes the display from sleep mode and plays product advertisements (which can be displayed on the upper and / or lower display); a visual sensor to capture facial features, gestures, and focus of attention of nearby customers (within 1 meter) and send the captured signal to the controller, which then controls the display to continuously show and present product information and order links that the customer is interested in; a voice sensor to capture the customer's voice description, extracting key semantic information such as product names, taste preferences, and purchasing needs, and sending the captured signal to the controller, which then pushes matching products to the display (3-5 candidate products can be displayed simultaneously); and a barcode scanner to scan the payment code on the customer's mobile phone or generate an order QR code for the customer to scan, or display it on the display. The control system on the controller includes a tasting module, a current order module, an external order module, a self-learning module, a drive control module, a signal acquisition module, and a central processing module. The self-learning module is equipped with convolutional neural network models, recurrent neural network models, deep reinforcement learning convolutional network models, memory enhancement network models, and graph neural network models. When a potential customer stops in front of the sales counter, the display shows which items have touch buttons for tasting. The customer can click the corresponding touch button to try the item. During the tasting, the customer will exhibit corresponding facial expressions and / or verbal descriptions. The visual acquisition device captures the customer's facial features and posture information, which is then analyzed by the visual acquisition module and transmitted to the central processing module. The central processing module feeds the feature data into the convolutional neural network model of the self-learning module for feature vector extraction, and then processes the contextual feature vectors through the recurrent neural network model. The system identifies the customer's age group and whether their facial expressions show curiosity or interest. Based on this information, the central processing module pushes and displays the results on the monitor. The system provides textual and visual descriptions of the corresponding items. Attracted by the displayed content, potential customers ask questions and have their voice signals captured by a sound acquisition device. After processing by the sound acquisition module, the signals are transmitted to the central processing module. The central processing module then sends the voice features to the self-learning module for further processing. A convolutional neural network model extracts voice feature vectors, and a recurrent neural network model performs semantic understanding to identify the customer's preferences for specific items. The self-learning module also performs deep reinforcement learning decision-making. If it's a first visit and there's no historical record, the data is stored for future use. If it's a repeat visit, a memory reinforcement network model retrieves the customer's previous behavioral memories, and a graph neural network model analyzes the relationships between products to ultimately output a recommendation decision. The central processing module receives the decision. Afterwards, the controller displays an order link for the entire boxed item on the monitor, along with order guidance text. The central processing module displays the order link, such as an order QR code, through the current order module. Potential customers can place an order directly by clicking the link on the touchscreen or scanning the QR code. After clicking the link and selecting to purchase two boxes, the customer completes payment by scanning their mobile payment code or paying directly on their phone. Upon receiving a successful payment signal, the controller sends a command to the storage unit via the drive control module. This commands the small motor to rotate forward, driving the shaft through a reducer. The left and right lower side doors rotate outward synchronously to open, or the side with the item being displayed rotates outward independently. The corresponding reciprocating electric cylinder of the storage unit containing the item... Upon startup, the pusher plate is driven forward, pushing the two boxes of items out of the end of the storage unit in sequence. Each time an item passes, an infrared sensor collects a passing signal and sends it back to the controller for counting. After leaving the storage unit, the items enter the inclined conveyor pipe and slide down to the retrieval platform by gravity. A weight sensor on the retrieval platform detects the item's arrival (weight increases) and sends a signal to the controller, which then prompts the customer to retrieve the item via a display. After the customer takes the two boxes from the retrieval platform, the weight sensor detects the weight has returned to zero and sends a signal to the controller. The controller waits 3 seconds to confirm there are no other requests before controlling a small motor to reverse, driving the lower door panel to close. The display shows a successful purchase, and the device automatically enters sleep / standby mode after 10 seconds.When the infrared sensor of the shelf continuously detects no goods passing through (i.e., the shelf is empty), the controller sends a restocking notification to the administrator's mobile phone via the wireless communication module. This notification includes the shelf number, the name of the out-of-stock item, and the quantity out of stock. Upon receiving the notification, the administrator promptly restocks. If a potential customer samples the item and expresses satisfaction, but the item is sold out (the infrared sensor detects no stock), the controller's order module automatically activates, displaying purchase links for nearby offline stores (based on GPS location, showing convenience stores with stock within a 500-meter radius) and online stores (partner e-commerce platforms) for potential customers. Once a customer places an order, they can choose to pick it up at a nearby store or have it delivered online, ensuring an uninterrupted shopping experience. During each interaction, all data collected by the signal acquisition module (including the customer's behavioral patterns, voice preferences, taste test choices, and purchase decisions) is transmitted through the central processing module to the self-learning module for model training. The convolutional neural network model continuously optimizes feature extraction capabilities, the recurrent neural network model continuously improves semantic understanding accuracy, and the deep reinforcement learning convolutional network model, in collaboration with the memory enhancement network model and the graph neural network model, continuously optimizes the accuracy of the recommendation strategy. As usage increases, the system becomes increasingly accurate in recognizing the preferences of frequent customers, leading to a continuous improvement in recommendation conversion rates. All data here undergoes secure encryption to prevent the leakage of customer information.

The display is used to show the order links of the current order module and the external order module. The control system is equipped with a self-learning module, a drive control module, a signal acquisition module, and a central processing module. The self-learning end of the central processing module is electrically connected to the self-learning end of the self-learning module. The drive end of the central processing module is electrically connected to the drive end of the drive control module. The control end of the drive control module is electrically connected to the control end of the tasting mechanism and the control end of the container, respectively. The acquisition end of the central processing module is electrically connected to the acquisition signal end of the signal acquisition module. The display end of the central processing module is electrically connected to the display end of the monitor. The self-learning module is equipped with a convolutional neural network model, a recurrent neural network model, a deep reinforcement learning convolutional network model, a memory-enhanced network model, and a graph neural network model. The signal acquisition module transmits the acquired signals to the convolutional neural network model for feature vector processing through the central processing module. The convolutional neural network model then transmits the signals to the recurrent neural network model for context feature vector processing. Finally, the signals are processed by the deep reinforcement learning convolutional network model, which has a memory-enhanced network model and a graph neural network model working together, and then sent to the central processing module. The signal acquisition module includes a radar acquisition module, a vision acquisition module, a sound acquisition module, and a barcode acquisition module. These modules are mounted on the control system. The radar acquisition module is electrically connected to the radar acquisition unit, the vision acquisition module is electrically connected to the vision acquisition unit, the sound acquisition module is electrically connected to the sound acquisition unit, and the barcode acquisition module is electrically connected to the barcode acquisition unit.
