Description

Technical Field

[0001] The invention relates to a weight loss charging device and belongs to the field of self-service catering. Background Art

[0002] At present, the self-service catering weighing devices on the market mainly use a single weighing sensor connected to the main controller, which detects the weight and amount on the main controller and observes the weight and amount on the auxiliary display. In similar scenarios such as spicy hot pot or self-selected dishes, the cost of dishes is different, and the settlement unit price should be different. However, due to the lack of measurement methods, shops often choose to settle consumers at an average price (same price for meat and vegetables, etc.), which makes consumers feel unfair. At the same time, shops will think that the cost of vegetarian dishes is also high, but if the price is high, it will lead to customer loss, which will fall into a vicious circle.

[0003] The Chinese patent document with the announcement number CN221101445U discloses a self-service intelligent dining table, including a weighing table, on which a number of weighing areas and identification areas are arranged, a weighing unit is arranged in the weighing area, and an identification unit for identifying a plate is arranged in the identification area; an image acquisition unit, a display unit, a speaker unit, a central processing unit and a payment unit are arranged above the weighing table, and the central processing unit is electrically connected to the weighing unit, the identification unit, the image acquisition unit, the display unit, the speaker unit and the payment unit respectively. Different unit prices are set for different dishes, and different unit prices of dishes need to be placed in different types of plates, different types of plates are placed in different dining areas, and different types of plates are equipped with magnetic parts matching different weighing areas. When picking up the meal, each customer needs to place the plates with magnetic parts placed in different dining areas in the corresponding weighing area to be correctly weighed and charged, so that different unit prices can be set for dishes of different costs and accurate charging can be achieved. However, the meal pick-up and payment process is relatively complicated, and the dining table uses a large number of magnetic components, Hall switches and other related devices, which is costly.

[0004] The Chinese patent document with publication number CN117854205A discloses a weight-reduced billing method and device based on intelligent weighing settlement, the method includes: judging whether it is a valid meal pickup time period; during the invalid meal pickup time, the intelligent weighing component reads the original weight G of the scale body and the real-time weight X; based on the preset time interval T and the preset evaporation threshold Z, the real-time weight is updated in real time; during the valid meal pickup time, the intelligent weighing component reads the original weight G of the scale body with the intelligent tray placement time as the reference time; based on the preset time interval T, the tray information is read; based on the weight-reduced billing algorithm, the user's consumption is obtained; if the user does not continue to consume within the preset time period, the consumption settlement is completed. The weight-reduced billing device in the invention includes a judgment module for judging the meal pickup time period, a real-time weight update module for reading weight, a weight-reduced billing algorithm module for calculating the meal pickup weight and amount, and a consumption settlement module for completing settlement. The weight-reduced billing device of the invention can reasonably calculate the weight of the meal picked up by the consumer at the dining table, and the reduced weight (i.e., the weight of the meal picked up by the customer) can be directly calculated after the meal is picked up. The customer does not need to weigh the meal specifically, and at the same time, the meal plate and magnetic components are saved, thus saving costs. However, in actual applications, the cafeteria has a large flow of people, and congestion and disorder are prone to occur only through simple weighing and settlement by the device. If there is a situation of queue jumping, card swiping error, or multiple people consuming at the same time when picking up the meal, billing errors are likely to occur, resulting in the inability to trade smoothly, affecting the customer experience and settlement efficiency. Summary of the invention

[0005] The object of the present invention is to provide a weight-reducing billing device, which is used to solve the problem of difficult billing or wrong billing caused by the order of picking up meals when settling at a buffet counter.

[0006] To achieve the above object, the solution of the present invention includes: A weight loss billing device of the present invention is characterized in that it includes at least two weighing sensors for weighing meal plates, a main controller connected to the weighing sensors, and an identity authentication module connected to the main controller for identity authentication; the main controller is used to charge according to the reduced weight of the corresponding meal plate obtained by the weighing sensors after the user's identity is confirmed.

[0007] Furthermore, the main controller is used to wait for user identity confirmation through the identity authentication module. When the user identity is confirmed and the corresponding plate weight is detected to be reduced through the weighing sensor, the consumption amount is calculated based on the reduced weight and the corresponding unit price, and wait for the user to check out; after completing the checkout, wait for user identity confirmation again.

[0008] Furthermore, the main controller detects the weight change of the corresponding plate in real time through the weighing sensor, and issues an alarm when there is no user identity confirmation and the weight of the corresponding plate decreases.

[0009] Furthermore, there are more than two weighing sensors, and the dinner plates corresponding to different weighing sensors are used to place dishes of different unit prices or different types.

[0010] Furthermore, it also includes an alarm device that is communicatively connected to the main controller and is used to remind users who directly pick up food without identity authentication.

[0011] Furthermore, the identity authentication method of the identity authentication module includes face recognition, fingerprint recognition, palm print recognition, card reading or code scanning.

[0012] Furthermore, the prompting method of the alarm device includes a warning light, a horn or a display prompting picture.

[0013] Furthermore, it also includes a display connected to the main controller for displaying consumption details, nutritional information and customer information.

[0014] Furthermore, the main controller also includes a communication module for uploading relevant order data to the cloud platform.

[0015] The beneficial effects of the present invention are: The present invention is a pioneering invention. In the weight-reducing billing device of the present invention, the main controller can be connected to multiple weighing sensors. The main controller is also connected to an identity recognition module, an alarm device, etc. By arranging the weight-reducing billing device at the buffet table, it is possible to enable users to pick up meals after identity authentication. The table can directly settle accounts according to the weight-reducing billing method, which can ensure the order when picking up meals and is not prone to erroneous billing caused by multiple people picking up meals at the same time. The order of picking up meals established according to the device of the present invention ensures that consumers are authenticated before picking up meals and charging, and enter the next round of identity authentication after completing checkout. This can avoid erroneous billing caused by poor order in picking up meals, provide basic information services for merchants' food inventory and preparation guidance, reduce the management costs of operators, and provide dining customers with dining details and other information in a timely manner.

[0016] Furthermore, when there is no user identity confirmation and the weight of the plate is reduced, no billing will be performed but an alarm will be issued to ensure the standardization of the dining process, that is, food pickup is not allowed if it is not bound.

[0017] The order established by the device of the present invention can ensure that customers bind their identities before picking up their meals, and can display the data of each dish to consumers in real time, thereby improving consumers' autonomy in picking up their meals. Through background statistical data, operators can also obtain information on dish consumption and provide data guidance for food preparation. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The figure includes: a table body 1; a partition 2; a dining tray 3; a dining tray support 4; a baffle 41; a display 5; and an identity recognition module 6. DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] The idea of ​​the present invention is to provide a weight-reduced billing device, in which a main controller can be connected to multiple weighing sensors, and the main controller is also connected to an identity recognition module, an alarm device, etc. By arranging the weight-reduced billing device at a buffet table, it is possible to enable users to pick up meals after identity authentication, and the table can directly settle accounts according to the weight-reduced billing method, which can ensure the order when picking up meals and is less likely to cause erroneous billing due to multiple people picking up meals at the same time; the data on the use of each dish can be displayed to consumers in real time, thereby improving the autonomy of consumers in picking up meals. Through background statistical data, operators can also obtain information on dish consumption and provide data guidance for preparing dishes.

[0022] Example: like Figure 1 In the weight loss charging device shown, the main controller is connected to multiple weighing sensors at the same time. At the same time, the main controller is also connected to the identity recognition module, the alarm device and the display; the main controller can also upload data to the cloud platform.

[0023] The main controller in the device is used to connect multiple weighing sensors at the same time. When the user takes multiple dishes at the current table, the weight of each dish and the total weight of the dishes can be directly calculated, and then the consumption details (including the consumption amount of each dish and the total consumption amount) can be calculated; at the same time, the main controller is also connected to the identity recognition module, which is used to authenticate the user who picks up the meal. When picking up the meal, the user must first perform identity authentication before picking up the meal; the main controller is also connected to an alarm device. When the user directly picks up the meal without identity authentication, the alarm device will be used to remind the user; the main controller is also connected to a display, which is used to display dining data, dish information, consumption details and user information, etc.; the main controller can also upload data to the cloud platform so that the merchant can read the background data.

[0024] Among them, the main controller and the weighing sensor are connected by wired communication. Plates with different dishes can be placed on multiple weighing sensors. The main controller collects data from the weighing sensors connected to it in real time, associates the collected data with the local weight loss billing algorithm and nutritional information, and calculates the consumption details and nutritional content; The main controller and the identity recognition module are connected by wired or wireless communication. The identity recognition module can realize identity authentication including face recognition, fingerprint recognition, palm print recognition, code scanning or card reading, etc. The main controller obtains the identity authentication result of the identity authentication module to carry out subsequent processes; The main controller is connected to the display by wired or wireless communication. The display is used to display the number of meals taken by the user, consumption details and nutritional information. When calculating nutritional information, the nutritional components per unit weight of different dishes (dish calories, carbohydrate content, vitamin content, protein content, etc.) are multiplied by the corresponding meal weight and then summed to calculate the nutritional information; The main controller and the alarm device are connected by wired or wireless communication. When a user directly picks up food without authentication, the alarm light, horn or prompt screen are used to remind the user to follow the merchant's procedures. The main controller communicates with the cloud platform via TCP, WiFi or other wireless communication methods, and uploads the order information to the cloud in order to count the background data, understand the transaction status, and facilitate subsequent meal preparation.

[0025] The method of using the weight loss charging device includes the following contents: 1) After the weight reduction charging device is in operation, configure the number of external weighing sensors and the relevant parameters of the corresponding sales items, clarify the unit price and ancillary information (parameters such as nutritional content), and carry out initial distribution, put different plates into different plates, place the plates on the corresponding different weighing sensors, and achieve the stability of the weighing sensors; 2) The display shows user identification prompts, guiding the user to authenticate through face recognition, fingerprint recognition, palm print recognition, card insertion, card swiping or code scanning; 3) The main controller collects the weight of each plate in real time and waits for the user to authenticate their identity; 4) After the user completes the identity authentication, the weight change of each weighing sensor is collected in real time, and the weight reduction of the plate will be detected after the user picks up the meal; 5) Perform local calculations based on the weight-loss charging calculation method described in the Chinese patent document with publication number CN117854205A, calculate the amount of different dishes taken by the user, and then add the amounts of different dishes to calculate the total consumption amount; 6) Wait for the user to check out; 7) After checkout is completed, wait for the next identity verification.

[0026] As another implementation method: while waiting for user identity authentication, if it is detected that the weight of the plate has been reduced, the user will be prompted to authenticate first and then pick up the meal by means of an alarm light and a corresponding screen displayed on the display. The weight of the meal picked up before authentication will be calculated into the current bill. The user can pick up the meal after confirming and authenticating his identity.

[0027] As another implementation: if a reduction in the weight of the plate is detected while waiting for user identity authentication, checkout cannot be performed.

[0028] As another implementation method: after the user identity is authenticated and it is detected that the weight of the meal plate has been reduced but the checkout has not been completed, if another user performs identity authentication, the user is prompted to complete the current checkout before proceeding with the next meal pickup process.

[0029] In practical applications, multiple buffet tables can be set up as needed. By arranging the weight-reducing charging device at each table, multiple users can pick up food at the same time. After the arrangement is completed, a single table can be Figure 2 As shown in the figure, serial number 1 refers to the entire dining table, a partition 2 is set on the side of the dining table 1, multiple dining plates 3 can be placed inside the dining table 1, the identity recognition module 6 is placed on the user side, and the display 5 is set above the dining table; the dining table before placing the dining plates is as shown in FIG. Figure 3 As shown, the meal tray is placed on a set meal tray support 4, and a baffle 41 for placing and moving the meal tray is provided at the edge of the meal tray support. Users can perform identity authentication, pick up meals and check out at each dining table according to the merchant's process.
