The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] Figure 1 A structural diagram of an embodiment of the non-contact self-service restaurant system provided by the present invention is shown as follows: Figure 1 As shown, the non-contact self-service restaurant system 10 includes: an access control terminal 100, a food metering terminal 200, a server terminal 300 and a mobile terminal 400; The access control terminal 100 is used to generate a customer dining signal and a dining completion signal, and send the customer dining signal and the dining completion signal to the server terminal 300; The dish metering terminal 200 is used to generate meal pickup information and send the meal pickup information to the server terminal 300; The server 300 is used to generate dining order information after receiving a dining signal from a customer, and to generate a bill to be paid according to the dining order information and the meal pick-up information after receiving a dining completion signal, and to send the bill to be paid to the mobile terminal 400; The mobile terminal 400 is used for identity registration, bill display and payment authorization.

[0024] Compared with the prior art, the contactless buffet restaurant system provided in the embodiment of the present invention automatically records the type and quantity information of each dish taken by the customer through the dish metering terminal, and automatically calculates the fee based on the meal collection information. This can realize the refined charging of each dish in the buffet restaurant, so that customers can choose dishes according to their own preferences, thereby improving the customer's dining experience.

[0025] In some embodiments of the present invention, Figure 2 FIG. 1 is a schematic diagram of the structure of the access control terminal according to an embodiment of the present invention. Figure 2As shown, the access control terminal 100 includes an entrance terminal 110 and an exit terminal 120; The entry terminal 110 is used to identify the user identity credentials of the customer entering the restaurant and generate a customer dining signal according to the user identity credentials; The exit terminal 120 is used to identify the identity matching information of the customer leaving the restaurant and generate a dining completion signal according to the identity matching information.

[0026] Specifically, in the embodiment, the access control terminal 100 is divided into an entrance terminal 110 and an exit terminal 120. When a customer passes through the restaurant entrance, the entrance terminal uses face recognition to identify the user identity credentials of the customer entering the restaurant. After successful recognition, a customer dining signal is generated and sent to the server terminal 300, and the customer is allowed to enter the restaurant. When the customer passes through the restaurant exit, the exit terminal 120 uses face recognition to match the customer leaving the restaurant with the customer dining to obtain identity matching information. After successful matching, a dining completion signal is generated and sent to the server terminal 300, and the customer is allowed to leave the restaurant.

[0027] In some embodiments of the present invention, the contactless buffet restaurant system 10 also includes a local database 500, which is used to generate and save dining customer information based on user identity credentials when receiving a customer dining signal, and to delete the corresponding dining customer information based on identity matching information when receiving a dining completion signal.

[0028] Specifically, in order to improve the system response speed, the contactless self-service restaurant system 10 in the embodiment also includes a local database 500. When the access control terminal recognizes that a customer enters the restaurant, the system generates dining customer information based on the recognized customer facial data and user identity credentials and saves it in the local database, and deletes the corresponding dining customer information when it is recognized that the customer leaves the restaurant. In this way, the embodiment can use a smaller database to save the facial information of dining customers, and when facial recognition is required, only less facial data needs to be matched, which greatly reduces the time required for facial recognition and the demand for equipment performance, and reduces the cost of the entire system.

[0029] In some embodiments of the present invention, Figure 3 Schematic diagram of the structure of the food metering terminal according to an embodiment of the present invention. Figure 3 As shown, the dish measuring end 200 includes a dish identification unit 210, a weighing unit 220, a meal picking customer identification unit 230 and a measuring unit 240; The dish identification unit 210 is used to identify the dish category; The weighing unit 220 is used to monitor the weight change data of the dishes; The meal pickup customer identification unit 230 is used to identify the meal pickup customer; The metering unit 240 is used to generate meal pickup information according to the dish category, dish weight change data and the meal pickup customer, and send the meal pickup information to the server 300 .

[0030] Specifically, the dish metering end 200 can accurately measure the amount of food taken by the customer when the customer takes the food and generate the food taking information, so that the buffet restaurant can charge each dish in a refined manner, so that the customer can take as much as he or she eats, and the type of food he or she eats is charged according to the type of food. The customer can take the food according to his or her own needs and preferences, which effectively improves the customer's dining experience. Among them, the dish metering end includes a dish identification unit 210, a weighing unit 220, a meal-taking customer identification unit 230, and a metering unit 240. The dish identification unit 210 identifies the current dish category through image recognition, and there is no need to bind the plate to the dish, making the logistics work more convenient and flexible. For example, for more popular types of dishes, multiple plates can be set for provision. The weighing unit 220 uses an electronic scale placed under the dish plate to weigh the weight of the upper dish (including the plate) in real time, and calculates the weight of the current dish consumed by the customer based on the total weight before the customer takes the dish minus the total weight after the customer takes the dish, and the weighing action can be automatically completed without the participation of the customer. In the embodiment, the weighing unit 220 uses a highly sensitive electronic scale, which can complete weighing within 0.2 seconds, which is helpful to distinguish specific customers when multiple people pick up food. The customer identification unit 230 performs facial recognition on the customer who is currently picking up food, and matches it with the facial information in the local database 500 to determine the customer who is picking up food. The metering unit 240 generates food pickup information based on the category of dishes, the weight change data of dishes, and the customer who picks up food, which is used to record the category and weight of each customer's food, and then sends it to the server 300.

[0031] In some embodiments of the present invention, Figure 3 As shown, the dish measuring terminal 200 further includes a meal taking action recognition unit 250 and a meal taking ratio recognition unit 260; The meal picking action recognition unit 250 is used to obtain meal picking action information through action recognition when multiple meal picking customers pick up meals, determine the meal picking order according to the meal picking action information, and generate meal picking information according to the meal picking order, dish category, dish weight change data and meal picking customers; The meal pick-up ratio recognition unit 260 is used to obtain the meal pick-up ratio through image recognition when the meal pick-up action recognition unit cannot recognize the meal pick-up order, and to generate meal pick-up information based on the meal pick-up ratio, dish category, dish weight change data and the customer who picks up the meal.

[0032] Specifically, considering the nature of self-service meal pickup, there are many customers picking up meals at the same time in the restaurant, and it is very likely that more than one customer will pick up dishes from the same plate, and it is necessary to clearly distinguish which customer has consumed how many dishes. To this end, the dish metering end 200 in the embodiment also includes a meal pickup action recognition unit 250 and a meal pickup ratio recognition unit 260. The meal pickup action recognition unit 250 is used to identify the actions of customers picking up meals, and obtain meal pickup action information based on the location and hand movements of each customer. When there is a sufficient time difference between the actions of each customer picking up dishes, the order of picking up dishes can be determined by the meal pickup action information, and the dish weight change data obtained by the weighing unit 220 can be used to accurately calculate the weight of each customer's meal. When the actions of each customer are too synchronized and the time difference is insufficient for the meal picking action recognition unit 250 to recognize the order of meal picking, the embodiment first determines the customer who picks up the meal through the meal picking action information, and then the meal picking proportion recognition unit 260 estimates the proportion of each customer in the total weight of the dishes taken this time through image recognition based on the relative area sizes of the dishes taken by each customer in the picture, thereby calculating the weight of the dishes consumed by each customer separately.

[0033] In some embodiments of the present invention, Figure 4 FIG. 1 is a schematic diagram of the structure of the server side of an embodiment of the present invention. Figure 4 As shown, the server side 300 includes an order generating unit 310, a data storage unit 320 and a bill settlement unit 330; The order generating unit 310 is used to generate dining order information according to the dining signal of the customer after receiving the dining signal of the customer; The data storage unit 320 is used to store the unit price of dishes and dining order information; The bill settlement unit 330 is used to generate a bill to be paid according to the dining order information, the unit price of dishes and the meal pickup information, and send the bill to be paid to the mobile terminal 400 .

[0034] Specifically, in the embodiment, the bill of each customer is calculated by the server end 300. After receiving the customer dining signal from the access control end 100, the order generation unit 310 generates dining order information according to the customer dining signal. The generated dining order information includes the customer type, various basic information of the customer and the start time of dining, and is stored in the data storage unit 320. In addition, the data storage unit 320 also stores the unit price of dishes. The bill settlement unit 330 automatically calculates and generates the bill to be paid according to the dining order information and the unit price of dishes stored in the data storage unit 320, and the meal pickup information received from the dish metering end 200, and sends the bill to be paid to the mobile terminal 400.

[0035] In addition, the server side 300 can also perform some other functions by setting up various modules, such as a historical dining order module, where staff can manage and view historical dining order information and evaluate the restaurant's business conditions; a dish unit price modification module, where staff can adjust the dish unit price according to the dish cost; a payment bill modification module, which can modify the bill to be paid when there is a problem with billing, etc.

[0036] In some embodiments of the present invention, Figure 5 Schematic diagram of the structure of a mobile terminal according to an embodiment of the present invention. Figure 5 As shown, the mobile terminal 400 includes a bill display and payment unit 410 for displaying bills and completing bill payment after obtaining customer authorization.

[0037] Specifically, after the customer finishes his meal and generates a bill to be paid, the contactless buffet restaurant system 10 sends the bill to the customer's mobile terminal 400. If the customer has authorized automatic deductions, the payment system can automatically deduct the money. If the customer has not authorized automatic deductions, the customer will check the bill and confirm the payment. After the deduction or payment is completed, the exit access will be opened and the customer can leave.

[0038] In some embodiments of the present invention, Figure 5 As shown, the mobile terminal 400 further includes an identity registration unit 420 and a temporary identity registration unit 430; The identity registration unit 420 is used to register user identity credentials; The temporary identity registration unit 430 is used to register a temporary identity credential, and the temporary identity credential can be bound to the user identity credential.

[0039] Specifically, customers who visit for the first time can register their user identity credentials through the identity registration unit 420. When the access control terminal 100 recognizes the user identity credentials, they can enter the restaurant. The user identity credentials need to be bound to the user's payment account and facial information, etc., and uploaded to the server 300 or a dedicated data center through the network for storage. In addition, the customer's registration information can be identified in different franchised restaurants, and the customer only needs to register an account once to use it in all restaurants. At the same time, the mobile terminal 400 also includes a temporary identity registration unit 430. Registered users can authorize the binding of unregistered users through the temporary identity registration unit 430. Authorized unregistered users can enter the restaurant to consume like registered users, and the bills are paid by the authorized registered user account. In addition, unregistered users can also choose to enter the restaurant as temporary customers through the temporary identity registration unit 430, and pay the bill by scanning the code at the exit.

[0040] In some embodiments of the present invention, Figure 5As shown, the mobile terminal 400 further includes a bill appeal module 440 for creating a bill appeal form when there is a dispute about the bill to be paid.

[0041] Specifically, since the bill of the contactless buffet restaurant system is automatically generated, when multiple people pick up food at the same time, the proportion of food picked up is determined by image recognition, which may be inaccurate. Customers who have objections to the bill can create a bill complaint form through the bill complaint module 440 to file a complaint, and the system or manual review will modify the bill or refund the fee.

[0042] In some embodiments of the present invention, the contactless self-service restaurant system 10 further includes a backend management terminal 600 for detecting restaurant food status and customer flow status, and managing user identity credentials and temporary identity credentials.

[0043] Specifically, to ensure the quality of service, the non-contact self-service restaurant system 10 also includes a backend management terminal 600, which can display the information of each customer in the restaurant, the remaining amount of dishes on each plate, the flow of people in the restaurant, etc., so as to facilitate the staff to manage the restaurant. When the remaining amount of dishes is less than the preset threshold, the backend management terminal 600 will remind the staff to replenish the dishes in time; when the customer has some dining needs, the mobile terminal 400 can also send a service request to the backend management terminal 600.

[0044] In summary, the contactless buffet restaurant system provided by the present invention automatically records the type and quantity information of each type of dishes taken by customers through the dish metering terminal, and automatically calculates the fees based on the pick-up information. This can realize the refined charging of each dish in the buffet restaurant, allowing customers to choose dishes according to their own preferences, thereby improving the customer's dining experience.

[0045] The above is a detailed introduction to the contactless buffet restaurant system provided by the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea; at the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation method and application scope.
