Description

Technical Field

[0001] The present invention relates to the technical field of vending cabinets, and more specifically, to a refrigerated vending cabinet based on intelligent cloud synchronization operation. Background Art

[0002] With the rapid development of modern technology, the application of intelligent devices and Internet of Things technology in daily life has become increasingly widespread. Traditional vending cabinets mainly rely on manual replenishment, temperature monitoring, and sales data recording, which have problems such as low efficiency, high cost, and inconvenient management. Especially in the field of frozen foods, due to the high requirements for temperature control, traditional vending cabinets often have difficulty in real-time monitoring and adjusting the internal environment, resulting in a decline in product quality or energy waste.

[0003] In recent years, the development of cloud synchronization technology and artificial intelligence has provided new solutions for the intelligentization of vending cabinets. By connecting vending cabinets to cloud servers, remote monitoring, data collection, and analysis can be achieved, thereby improving operation efficiency and reducing maintenance costs. However, existing intelligent vending cabinets mostly focus on normal-temperature products and still have deficiencies in meeting the special needs of frozen products, lacking efficient inventory management and user interaction functions.

[0004] When using a refrigeration blower to blow cold air towards products for preservation, similar products are placed in different compartments. Due to the different quantities and sizes of the products, the compartments accommodating the products are not convenient for adaptive regulation. If the products in a compartment are sold out, the blower still blows fully towards the entire inner cavity of the vending cabinet or the entire large compartment, resulting in waste of resources and non-concentration of cold air, and it is not convenient to preferentially cool the unsold products centrally. In view of this, we propose a refrigerated vending cabinet based on intelligent cloud synchronization operation. Summary of the Invention

[0005] The purpose of the present invention is to provide a refrigerated vending cabinet based on intelligent cloud synchronization operation to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides a refrigerated vending cabinet based on intelligent cloud synchronization operation, including a front end and a back end for data synchronization monitoring with the front end. The front end includes a cabinet body, a data collection unit, and a space control unit, where:

[0007] The interior of the cabinet body is partitioned into a vending cavity and a refrigeration cavity. A cold air blower is provided inside the refrigeration cavity. Multiple partition plates are provided inside the vending cavity, and the multiple partition plates divide the interior of the vending cavity into multiple compartments for placing products. A capacity regulation component for regulating the placement space is provided inside each compartment.

[0008] The data acquisition unit is used to collect the product ratio in the compartment, and after sensing the sales signal, trigger the re - collection of the product ratio. The space control unit is used to drive the cooling fan to supply cooling in real - time and set the product ratio threshold. If the product ratio output by the data acquisition unit is 0, then adjust the product ratio threshold to 0. If the product ratio output by the data acquisition unit is not 0, then adjust the product ratio threshold to k, and control the capacity regulation component to slide on the top of the partition board until the product ratio output by the data acquisition unit meets the product ratio threshold.

[0009] As a further improvement of this technical solution, the capacity regulation component includes a barrier structure slidably inserted into the side wall of the sales cavity. The edge of the barrier structure is adapted to fit the size of the compartment, and a cylinder is fixedly connected to the inner wall of the refrigeration cavity. The end of the piston rod of the cylinder is fixedly connected to the inside of the barrier structure.

[0010] As a further improvement of this technical solution, multi - stage extension parts are arranged at both ends of the barrier structure. The multi - stage extension parts are composed of multiple movable plates sleeved and slidable, and are used to extend and contract along with the barrier structure. The top and bottom of the barrier structure and the multi - stage extension parts are all adapted to fit the top and bottom of the inner cavity of the compartment.

[0011] As a further improvement of this technical solution, a plurality of drainage fans are embedded on the surface of the barrier structures. The air inlet end of the drainage fan is communicated with the refrigeration cavity, and the air exhaust end of the drainage fan is communicated with the inside of the compartment.

[0012] As a further improvement of this technical solution, a plurality of cylinders are fixedly arranged on the inner wall of the refrigeration cavity, and the end parts of the piston rods of the plurality of cylinders are respectively fixedly connected to the plurality of barrier structures.

[0013] As a further improvement of this technical solution, the data acquisition unit includes a temperature sensing module, a commodity sensing module and a payment feedback module;

[0014] The temperature sensing module is used to sense the real - time temperature in the sales cavity, set the temperature threshold, and use a numerical comparison algorithm to compare the real - time temperature with the temperature threshold. If the real - time temperature is greater than the temperature threshold, then output a cold air adjustment signal;

[0015] The commodity sensing module is used to sense the product ratio of the commodity in the compartment, and the output signals include the product ratio value and no ratio;

[0016] The payment feedback module is used to provide identity authentication to open the sales cabinet door, record the product ratio output by the commodity sensing module before and after opening the sales cabinet door, calculate the type, price and quantity of the products purchased by the user, send the payment information to the user through Bluetooth, pop up the payment interface, and at the same time trigger the restart of the commodity sensing module to update the product ratio.

[0017] As a further improvement of the present technical solution, the space control unit includes a cold air regulation module, a cylinder drive module, and a wind direction regulation module;

[0018] The cold air regulation module is used to sense the cold air adjustment signal of the temperature sensing module and transmit a control signal to the air cooler;

[0019] The cylinder drive module is used to receive the output signal of the product sensing module. If the output signal is the product occupancy ratio, the sum of the occupancy threshold and the product occupancy ratio is calculated and defined as the placement space. A control signal is transmitted to the cylinder to drive the barrier structure to slide, and the remaining space in the compartment is sensed. When the remaining space is the same as the placement space, the control of the cylinder is stopped;

[0020] If the output signal is no occupancy, the placement space is defined as 0, a control signal is issued to drive the cylinder to make the surface of the barrier structure fit the inner wall of the vending cavity, and the wind direction regulation module senses the diversion fan corresponding to the placement space of 0, and a power-off signal is issued to drive the diversion fan to stop working.

[0021] As a further improvement of the present technical solution, the terminal includes a data query module and a warning reminder module;

[0022] The data query module is used to receive the type, price, and quantity of the products purchased by the user output by the payment feedback module, compare with the initial data, and output the sales status to facilitate the staff to record the data;

[0023] The warning reminder module is used to receive the no-occupancy signal output by the product sensing module, issue a replenishment signal to remind the staff, and set a waiting duration. If the temperature sensing module still issues a cold air adjustment signal after the waiting duration is reached, a fault signal is issued to remind the staff.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] The present invention realizes that the barrier structure can automatically control the capacity of the placement space in the compartment according to the products in the compartment. When there are no products, the compartment is completely blocked, so that the cold air flowing inside the vending cavity does not flow into the above-mentioned compartment. Without changing the cold air output volume, the entire space capacity inside the vending cavity becomes smaller, making the cold air gather more quickly, with a better cooling effect, and is beneficial to the cold air to preferentially refrigerate and preserve the products that have not been sold yet;

[0026] When there are products in the compartment, the placement space is intelligently reduced. On the one hand, the occupied space of the cold air is reduced, enabling the cold air to be more concentrated in refrigerating and preserving the unsold products. On the other hand, the range of product movement is restricted, preventing the products from being damaged due to large shaking ranges after external impacts. At the same time, on the basis of meeting the product placement, there is still a space of k for the cold air to flow, which is conducive to achieving the effect of refrigerating and preserving the products.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1-6 As shown, this embodiment provides a refrigerated vending cabinet based on intelligent cloud synchronization operation, including a front end 100 and a rear end 200 that synchronizes data monitoring with the front end 100. The front end 100 includes a cabinet 110, a data acquisition unit 120, and a space control unit 130, where:

[0038] The interior of the cabinet body 110 is partitioned to form a vending cavity 111 and a refrigeration cavity. A cold air blower 116 is provided inside the refrigeration cavity. A plurality of partition plates 112 are provided inside the vending cavity 111. The plurality of partition plates 112 divide the interior of the vending cavity 111 into a plurality of compartments for placing products, enabling multiple types of products to be placed separately, reducing mutual influence. A capacity adjustment component for adjusting the capacity of the placement space is provided inside each compartment;

[0039] The data acquisition unit 120 is used to collect the product occupancy ratio in the compartment, and after sensing the sales signal, triggers the re - collection of the product occupancy ratio. The space control unit 130 is used to drive the cold air blower 116 to supply cold air in real - time and set the product occupancy ratio threshold. If the product occupancy ratio output by the data acquisition unit 120 is 0, then the product occupancy ratio threshold is adjusted to 0. If the product occupancy ratio output by the data acquisition unit 120 is not 0, then the product occupancy ratio threshold is adjusted to kk means that there is a product placed on the partition plate 112. When the product occupies a certain proportion in the compartment, the capacity adjustment component is controlled to be within the k range of the proportion known by the product to meet the occupancy ratio threshold, giving the product a certain amount of space to avoid congestion affecting the cold air circulation. The capacity adjustment component slides on the top of the partition plate 112 until the product occupancy ratio output by the data acquisition unit 120 meets the product occupancy ratio threshold.

[0040] To enable the capacity adjustment component to adjust the capacity of the products to be placed in the compartment and ensure that the cold air can be more concentrated for preservation according to the product occupancy ratio. Therefore, as Figures 3-4 shown, the capacity adjustment component includes a barrier structure 113 slidably inserted into the side wall of the vending cavity 111. The edge of the barrier structure 113 is adapted to fit the size of the compartment, and a cylinder 115 is fixedly connected to the inner wall of the refrigeration cavity. The end of the piston rod of the cylinder 115 is fixedly connected to the inside of the barrier structure 113. By the linear movement of the piston rod of the cylinder 115, the barrier structure 113 is driven to slide inside the compartment;

[0041] When the data acquisition unit 120 collects that the product occupancy ratio output is 0, it means that there is no product in this compartment. The piston rod of the cylinder 115 drives the barrier structure 113 to slide into the compartment until the surface of the barrier structure 113 fits the inner wall of the vending cavity 111, realizing that the barrier structure 113 completely blocks this compartment, so that the cold air flowing inside the vending cavity 111 does not flow into the above - mentioned compartment. Without changing the cold air output volume, the entire space capacity inside the vending cavity 111 becomes smaller, enabling the cold air to gather more quickly, with a better cooling effect, and being beneficial for the cold air to preferentially refrigerate and preserve the products around those that have not been sold yet;

[0042] When the data acquisition unit 120 collects that the product ratio output is not 0, it means that there are products in this compartment. If the product ratio is small, resulting in a large number of vacant positions in the compartment, it will also occupy the cold air and affect the refrigeration effect. Therefore, assuming that the product ratio requires a placement space of x1, the driving cylinder 115 drives the barrier structure 113 to slide, so that the barrier structure 113 slides to the remaining space x1 + product ratio threshold k in the compartment. On the one hand, the space occupied by the cold air is reduced, so that the cold air can be more concentrated on cooling and preserving the products that have not been sold. On the other hand, the range of product activities is limited to avoid damage caused by a large shaking range of the product after external impact. At the same time, on the basis of satisfying the product placement, there is still k space for cold air flow, which is beneficial to give the product a cooling and preservation effect.

[0043] Specifically, in order to improve the separation effect of the barrier structure 113, each compartment can be separated, such as Figures 4-5 As shown, multi-stage extension pieces 1130 are provided at both ends of the barrier structure 113. The multi-stage extension piece 1130 is composed of a plurality of movable plates that are sleeved and slidably connected, and is used to extend and contract with the barrier structure 113. The top and bottom of the barrier structure 113 and the multi-stage extension piece 1130 are adapted to fit the top and bottom of the inner cavity of the compartment, and a baffle is provided at the end of the movable plate at the end, so that it cannot completely slide out of the refrigeration cavity. When the barrier structure 113 completely slides into the compartment, the multi-stage extension piece 1130 extends with the barrier structure 113 to block the barrier structure 113. At the edge of the top of the plate 112, on the one hand, cold air from other areas cannot flow into this compartment, ensuring that the cold air gives priority to cooling unsold products. On the other hand, the barrier structure 113 and the multi-stage extension piece 1130 can fit the top and top of the inner cavity of the compartment for scraping, which is helpful to push foreign matter such as product residues and water droplets to the edge. Although the foreign matter storage area is not shown in the figure of this case, in actual use, those skilled in the art can easily think of supplementing the foreign matter storage area to improve the cleaning effect, which is conducive to more convenient and clean replenishment.

[0044] However, the compressor in the air cooler 116 sucks in the low-temperature and low-pressure gaseous refrigerant and compresses it into a high-temperature and high-pressure gaseous state. The high-temperature and high-pressure gaseous refrigerant enters the condenser, where the refrigerant releases heat to the surrounding environment through heat exchange with the outside air, thereby gradually cooling and liquefying from the gaseous state. The liquefied refrigerant passes through a throttling device such as a capillary tube or an expansion valve. Due to the throttling effect, the pressure and temperature of the refrigerant drop sharply and become a low-temperature and low-pressure liquid and gas mixture. The low-temperature and low-pressure refrigerant enters the evaporator, which is located in the sales cavity 111. In the evaporator, the refrigerant evaporates rapidly and absorbs the heat in the sales cavity 111, thereby reducing the temperature inside the sales cavity 111, thereby achieving the preservation of the product. In order to enable the cold air generated by the air cooler 116 to be concentrated and blown to the compartment where the product is placed, as shown again Figure 4As shown in the figure, a drainage fan 114 is embedded on the surfaces of multiple barrier structures 113. The air inlet end of the drainage fan 114 is communicated with the refrigeration cavity, and the air outlet end of the drainage fan 114 is communicated with the interior of the compartment. Among them, the drainage fan 114 includes a housing, a motor and a fan blade inside the housing. The output shaft of the motor is connected to the end of the fan blade. When the motor is powered on, the fan blade rotates to introduce the cold air generated by the cold air blower 116 inside the refrigeration cavity into the vending cavity 111. If products are placed in each compartment, the corresponding drainage fan 114 of the compartment is driven to work, and the cold air in the refrigeration cavity is sequentially introduced into the compartments where the products are placed to improve the concentration of the fresh-keeping effect. On the contrary, if there is no product in the current compartment, the corresponding drainage fan 114 stops working, which can reduce the waste of resources and also make the cold air in the refrigeration cavity be concentrated and introduced into the compartments with products, ensuring a more reasonable distribution of cold air and improving the utilization rate.

[0045] Specifically, in order to make the sliding of the barrier structure 113 on the top of the partition plate 112 more convenient, a plurality of cylinders 115 are fixedly arranged on the inner wall of the refrigeration cavity. The piston rod ends of the plurality of cylinders 115 are respectively fixedly connected to the plurality of barrier structures 113. When the cylinders 115 receive control signals, they make linear motions through the piston rods to drive the barrier structures 113 to slide at any time. At the same time, the multi-stage extension members 1130 move together with the barrier structures 113, so that compartments for placing products are formed between the partition plate 112, the vending cavity 111, the multi-stage extension members 1130 and the barrier structures 113, and the compartments are fully blocked.

[0046] Further, as Figure 6 shown in the figure, in order to master the condition of the front end 100, so as to facilitate subsequent consideration of whether adjustment is needed, the data acquisition unit 120 includes a temperature sensing module, a commodity sensing module and a payment feedback module;

[0047] The temperature sensing module is used to sense the real-time temperature in the vending cavity 111 and set a temperature threshold. A numerical comparison algorithm is used to compare the real-time temperature and the temperature threshold. If the real-time temperature is greater than the temperature threshold, a cold air adjustment signal is output. Since in different outdoor environments, the outdoor environment will have a certain impact on the temperature inside the vending cabinet. For example, when the outside temperature is relatively high, during the normal use of the cold air blower 116, the high temperature affects the temperature inside the vending cabinet, resulting in the temperature in the vending cavity 111 not reaching the optimal fresh-keeping temperature of the temperature threshold, which can affect the fresh-keeping effect of the products according to different product adaptabilities. Therefore, it is necessary to sense the temperature in real time to facilitate subsequent timely adjustment of the temperature output by the cold air blower 116. As for the temperature sensing module, such as a thermistor or an integrated temperature sensor chip, the collected temperature value is converted into an analog voltage signal, and these signals are transmitted to the control system (such as a single-chip microcomputer or a PLC) through the analog input interface. After analog-to-digital conversion (ADC) inside the control system, digital-form temperature data is obtained for subsequent temperature comparison and control decision-making;

[0048] The commodity sensing module is used to sense the product occupancy ratio of commodities in the compartment, and the output signals include the product occupancy ratio value and no occupancy. The product occupancy ratio value means that there are products in the compartment, and no occupancy means that there are no products in the compartment;

[0049] The payment feedback module is used to provide identity authentication to open the vending machine door, record the product occupancy ratios output by the commodity sensing module before and after the vending machine door, calculate the types, prices and quantities of products purchased by the user, send the payment information to the user via Bluetooth, pop up the payment interface, and at the same time trigger the commodity sensing module to restart and update the product occupancy ratio;

[0050] Specifically, the payment feedback module includes an inventory management system, which is used to record the product types and prices in each compartment at the initial stage, place the same products in the same compartment, realize multiple compartments corresponding to multiple types of products, and record the capacity or weight of each product. Through the commodity sensing module, the product occupancy ratio in this compartment under the initial state can be sensed, and the product quantity can be reflected through the product occupancy ratio. Of course, for some products that are easily squeezed, it is inaccurate to only reflect the quantity through the occupancy ratio of the product capacity. Therefore, those skilled in the art can use a weight sensor to assist in calculating the product quantity. For example, in the case of weight recognition, if the weight of a certain grid position decreases by 50 grams, and there is a preset weight of a commodity in the commodity feature library of 50 grams, then it is preliminarily determined that the user has taken the commodity. It can also be based on image recognition. The algorithm will analyze the commodity image captured by the camera, extract the key features of the commodity and match them with the data in the feature library, so as to realize recording information such as the inventory quantity and type of commodities in each commodity grid position in the compartment. When it is recognized that the user has taken a certain commodity, the inventory data will be updated in time, and the commodity sensing module will be triggered to restart and update the product occupancy ratio. At the same time, according to the price information of the commodity, it is called from the database to calculate the total amount that the user should pay, and then the payment information including commodity details, prices, etc. is sent to the user's mobile payment APP or displayed on the vending machine screen waiting for the user to scan the code for payment. After the user's payment is successful, the door of the vending machine is closed, and the vending machine will file this transaction, update its own inventory information, sales data, etc. If the user does not complete the payment within the specified time, such as exceeding the set time limit, the vending machine will send a reminder notice and may take corresponding measures, such as locking the commodity grid position, etc., to prevent the loss of commodities.

[0051] Then, in order to facilitate the control operation of the front-end facilities, the space control unit 130 includes a cold air regulation module, a cylinder drive module and a wind direction regulation module;

[0052] The cold air regulation module is used to sense the cold air adjustment signal of the temperature sensing module, transmit a control signal to the air cooler 116, increase the air outlet intensity of the air cooler 116, reduce the rapid cooling inside the vending cavity 111 caused by the rising external temperature, and ensure the product freshness preservation quality. For example, by increasing the rotation speed of the compressor or changing the operating parameters of the condenser and evaporator, etc., the refrigeration efficiency is improved, so as to quickly reduce the temperature in the vending cavity. When the temperature returns to a reasonable range, the cold air regulation module will send an instruction again to make the air cooler return to the normal working mode. When controlling the air cooler 116, a PWM interface can be used to send it to the controller of the air cooler through the PWM signal output interface. For example, if it is necessary to increase the rotation speed of the compressor to improve the refrigeration efficiency, the cold air regulation module will increase the duty cycle of the PWM signal to make the compressor operate at a higher frequency;

[0053] The cylinder drive module is used to receive the output signal of the commodity sensing module. If the output signal is the product occupancy ratio, it calculates the sum of the occupancy ratio threshold and the product occupancy ratio, defines it as the placement space, transmits a control signal to the cylinder 115 to drive the barrier structure 113 to slide, and senses the remaining space in the compartment until the remaining space is consistent with the placement space, then stops the control of the cylinder 115, which is beneficial to changing the capacity of the compartment according to the quantity of the product, that is, the product occupancy ratio, and avoiding that fewer products in a larger compartment cannot fully sense the cold air for freshness preservation, thus improving the freshness preservation quality;

[0054] If the output signal is no occupancy ratio, it defines the placement space as 0, issues a control signal to drive the cylinder 115 to drive the surface of the barrier structure 113 to fit the inner wall of the vending cavity 111, and makes the air flow direction regulation module sense the diversion fan 114 corresponding to the placement space of 0, and issues a power-off signal to drive the diversion fan 114 to stop working. On the one hand, it ensures that when there is no product, the placement space where the compartment is located can be completely blocked to reduce the cold air flowing here. On the other hand, stopping the diversion fan 114 from working not only avoids the cold air being led in an unnecessary direction and occupying the cold air, but also avoids the waste of resources.

[0055] Currently, connecting the vending cabinet to the cloud server can achieve remote monitoring, data collection and analysis, thereby improving the operation efficiency and reducing the maintenance cost. However, in order to enable the staff to perform efficient inventory management and user interaction, the terminal 200 includes a data query module and an early warning reminder module;

[0056] The data query module is used to receive the type, price, and quantity of products purchased by users output by the record payment feedback module, reflect the sales trends of vending cabinets, popular products, etc., provide a basis for inventory management and operation decision-making for staff, compare with the initial data, output the sales status, and count key indicators such as the number of sold products, remaining inventory, and sales amount. Generate visual reports based on the statistical data and display the sales situation of various products in forms such as bar charts and pie charts for easy viewing, querying, and analysis by staff;

[0057] The warning reminder module is used to receive the no-occupation ratio signal output by the commodity induction module, send a replenishment signal to remind the staff for convenient inventory management and timely product replenishment, and set a waiting duration (for example, 1 - 2 hours). If the temperature sensing module still emits a cold air adjustment signal (indicating that the temperature has not returned to normal) after reaching the waiting duration, a fault signal is sent to remind the staff to avoid the temperature remaining at an unfavorable temperature for preservation for a long time, which affects the quality of the product and is conducive to the staff to perform maintenance in a timely manner;

[0058] When controlling as described above, an industrial standard protocol can be adopted, which is a widely used industrial communication protocol. In this system, it can be used to implement communication between the space control unit 130 and other intelligent devices (such as temperature sensors with Modbus interfaces, cylinder controllers, etc.), support the master-slave communication mode, with the space control unit 130 as the master station and other devices as slave stations. For example, the space control unit 130 can periodically poll the status information of each slave station device (such as the real-time temperature of the temperature sensor, the position of the cylinder, etc.), and send control commands (such as driving the cylinder to move to a specified position) to the slave station device and make the slave station execute the operation.

[0059] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
