Description

Technical Field

[0001] The invention relates to the technical field of catering services, and more particularly to an automatic weighing and metering buffet device and a metering method. Background Art

[0002] At a time when the catering industry is constantly pursuing intelligence and efficiency, the existing weighing and metering buffet system came into being, successfully integrating automated metering and pricing technology into it. On the surface, this system seems to have brought great convenience to the operation and management of buffets at the theoretical level, achieving accurate cost control and efficient settlement processes.

[0003] However, when we delve into the actual usage scenarios of users, we find that there are many troubling problems. Especially in the critical link when users take dishes, due to the limitations of system design, the weight of the chopsticks or spoons used to pick up dishes will inevitably be included in the overall weighing data. This seemingly minor detail has triggered a series of chain reactions. Because in this case, when the user stands in front of the plate and faces the total weight data on the display screen that includes the weight of the chopsticks or spoons, he cannot directly obtain the true and accurate weight information of the dishes he has taken, and thus cannot know the corresponding precise price.

[0004] In order to get the accurate weight and price of the dishes themselves, users usually have no choice but to put the dish clip or spoon back into the buffet stove so that the system can weigh the dishes again. This process not only requires users to spend extra time and energy to complete this tedious action, but also easily causes congestion and chaos in the fast-paced buffet environment with people coming and going. After picking up the dishes, each user needs to pause, return, put back the dish clip or spoon, wait for weighing, and then pick up the dishes again. This repetitive process makes the originally smooth meal picking process fragmented, seriously reducing the overall meal picking efficiency, and to a certain extent destroys the user's joyful mood of enjoying food, which is not conducive to improving the quality of buffet service and shaping the reputation. Summary of the invention

[0005] The purpose of the present invention is to provide a buffet device and a measuring method for automatic weighing and measuring, which simplifies the meal picking process so that the price data seen by the user is only related to the actual weight of the dishes, and realizes real-time and accurate feedback of the dish weight and price, thereby improving the user experience and the overall efficiency of the buffet service.

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1 and 2 As shown, the present invention provides a buffet device for automatic weighing and metering, including a buffet stove 1, a processor, a weighing module 7, a display module 6 and an identification and binding module. The buffet stove 1 is provided with a tray slot 3 for accommodating a meal-taking tool 4 and a food bowl 2 for accommodating dishes. The tray slot 3 is provided with a position detection mechanism 5 for detecting the position status of the meal-taking tool in the tray slot 3. The position detection mechanism can monitor in real time whether a meal-taking tool 4 is placed in the tray slot 3, and continuously update the position status of the meal-taking tool: "in place" or "out of place" to the processor in real time, so that the processor can know the status of the meal-taking tool 4 in real time; The weighing module 7 is used to measure the weight data of the buffet stove 1. The weighing module 7 continuously weighs the buffet stove 1 and continuously sends the weight data to the processor, so that the processor continuously obtains the weight data and change status of the buffet stove 1. The identification and binding module is used to identify user information, generally used to identify user information bound to the meal tray 8, and at the same time send the identified user information to the processor to facilitate subsequent data analysis and processing; the ways to bind the meal tray to the user include: face recognition, placing an RFID chip in the meal tray / tray, and identifying the barcode on the side of the tray through the scanner on the weighing and metering device; regarding the identification of the chip or barcode, in actual application, it needs to be used in conjunction with the tray binding machine. When the user takes a tray or meal tray, the user information is bound to the meal tray or tray through the background identification APP, such as face recognition, code scanning or card swiping APP. When the user reaches the metering and weighing device, the user information bound to the tray or meal tray can be identified through the identification and binding module.

[0021] The recognition and binding module itself can integrate face recognition to directly input and identify the user's face information.

[0022] The processor is used to obtain the dish information and the weight data of the meal-taking tool, and is also used to calculate the price data according to the dish information, the weight data of the meal-taking tool, the position status of the meal-taking tool, the weight change data of the dining stove and the user information, wherein the price data refers to the price data calculated after comprehensively considering whether there is the weight data of the meal-taking tool in the weight change data and determining the actual meal-taking weight, so as to ensure that the calculated price is the weight of the meal-taking tool 4 itself removed, so that the user can see the intuitive meal-taking price; The display module 6 is used to display the weight change data, dish information, user information, and price data of the buffet stove 1. Specifically, the display module 6 is also used to display the position status of the meal picking tool, so that users or employees can observe the status of the meal picking tool 4 in real time.

[0023] As an embodiment of the present invention, the buffet device further includes a communication module, and the communication module is used for data transmission among the buffet stove 1, the weighing module 7, the display module 6, and the processor.

[0024] Specifically, the communication module is used to transmit the weight change data of the dining stove measured by the weighing module 7 to the processor and display module 6 in real time; Used to transmit information on whether the meal-taking tool 4 is in place detected by the position detection mechanism to the processor in real time; Used to transmit the user information identified by the identification and binding module to the processor in real time; It is used to transmit the dish information, meal-picking tool weight data, meal-picking tool position status, meal-picking stove weight change data, user information, and price data acquired by the processor to the display module 6 in real time.

[0025] In the present invention, the communication module is used to realize real-time transmission of information, ensuring that when the position status of food picking tools such as food clips or food spoons changes, or when the weight data of the food stove changes, the relevant information can be transmitted to the processor instantly and accurately, providing reliable data support for subsequent possible automated management processes or data statistical analysis.

[0026] Regarding the processor of the present invention, the processor is connected to a memory, and the memory stores dish information and meal-picking tool weight data.

[0027] The processor is also used to monitor the weight data obtained by the weighing module 7, and when the weight data decreases, the calculation and processing of the price data is triggered.

[0028] The processor is also used to calculate the user's personal amount data according to the user information after calculating the price data, and send it to the display module 6 for display.

[0029] In practical applications, the processor is also used to connect and control other electronic control modules of the buffet stove 1 and the weighing and metering device, such as the intelligent temperature management control of the buffet stove 1, other data display of the weighing and metering device, etc.

[0030] The processor in the present invention has an intelligent processing system and an efficient implementation feedback mechanism. It can perform accurate analysis and processing by calculation, integrate the data of the weighing module 7, the position detection mechanism, and complete complex logical judgment and calculation processes. The accurate calculation of the weight of the dishes, combined with the real-time detection of the position status of the meal-picking tools, can be completed efficiently in a short time. This series of intelligent processing processes greatly reduces the waiting time of users in the meal-picking process, so that users do not need to wait for a long time next to the metering host to wait for the system to respond and display information, and provides overall meal-picking efficiency, allowing users to complete the meal-picking operation more smoothly and quickly, fully meeting people's needs for efficient catering services in modern fast-paced life.

[0031] In actual application, the weighing module 7, the identification and binding module and the display module 6 are integrated into a weighing and metering device, which is used to support and weigh the buffet stove 1, to identify user information, and to display the data obtained and calculated by the processor.

[0032] like Figure 3 As shown, corresponding to the above-mentioned buffet device, the present invention also provides a metering method performed by the above-mentioned buffet device; wherein the steps of the metering method are as follows: S1, obtaining dish information and meal-picking tool weight data in advance through a processor; S2, measuring the weight data of the buffet stove 1 through the weighing module 7, and detecting whether the weight data of the buffet stove changes; if so, executing S3; S3, identifying the current user information by identifying the binding unit, and obtaining the position status of the meal-taking tool through the position detection mechanism, and then using the processor to uniformly obtain the above data; S4. The processor calculates the price data based on the dish information, the weight data of the meal-picking tool, the user information, the position status of the meal-picking tool, and the weight change data of the meal stove, and displays the price data through the display module 6.

[0033] The calculation method of price data in S4 is: S41, determining the position status of the meal-taking tool. If it is "in place", determining the weight change data of the dining stove as the meal-taking weight; if it is "not in place", determining the difference between the weight change data of the dining stove and the weight data of the meal-taking tool as the meal-taking weight; S42, obtaining the unit price of the dish in the dish information, and taking the product of the unit price of the dish and the weight of the meal as price data; S43. Update the personal balance data of the user information according to the price data.

[0034] The following is an embodiment of a practical application of an automatic weighing and metering buffet device and a metering method of the present invention: First of all, the application preparation steps of the entire buffet device: After the weighing and metering device having the weighing module 7, the identification and binding module, and the display unit is configured, the current dish information of the buffet stove 1 needs to be stored and determined in the processor, and the dish information includes the dish name, unit price, heating temperature, etc., and the weight of the meal-taking tool 4 configured in the tray slot 3 of the current buffet stove 1 is also recorded in the processor. The self-service stove used is a stove having a tray slot 3 for placing the meal-taking tool 4 separately, so that the meal-taking tool 4 and the dishes can be placed in the stove in an integrated manner, and the tray slot 3 is configured with a position detection mechanism for monitoring the position of the meal-taking tool 4 in the tray slot 3.

[0035] In actual application, the buffet stove 1 is placed on the weighing table of the weighing and metering device, and the weighing module 7 weighs and measures the entire buffet stove 1. At this time, the meal taking tool 4 is also placed in the plate rack 3, waiting for the user to take it.

[0036] When the user actually takes the meal, he takes the meal through the meal tray 8, and binds the user information on the meal tray 8. When the user arrives near the buffet stove 1 with the meal tray 8, he can take the meal through the meal taking tool 4 in the tray slot 3; When the user takes out the meal-taking tool 4, the weighing module 7 can directly monitor the weight change of the buffet stove 1, and the position detection mechanism also immediately detects that the position status of the meal-taking tool is "not in place", and then directly triggers the measurement processing operation of the processor.

[0037] When it is determined that metering is to be performed, the user information is obtained by identifying the binding module. At this time, the display module 6 will display the current position status of the meal-taking tool, and will also display part of the user information, generally data such as the user name and the user account balance; at this time, the processor can compare the change data of the buffet stove 1 with the weight data of the meal-taking tool. If the two are exactly the same, combined with the position status of the meal-taking tool being "not in place", it can be clearly determined that the user has not started to pick up the meal, and the current weight change data of the meal stove is caused by the meal-taking tool 4 being picked up, so no metering and billing will be done at this time. It should be noted that the calculation does not stop, but after the calculation, the data corresponding to the weight of the meal-taking tool 4 is automatically subtracted.

[0038] Therefore, when the user only takes the meal pickup tool 4 but does not pick up the meal, the amount displayed by the display module 6 does not include the meal pickup tool 4. That is to say, in this case, the amount data such as the meal pickup amount and the user account amount will not change.

[0039] When the user actually picks up the meal, the weight change data obtained by the weighing module 7 exceeds the weight of the meal picking tool 4, and the processor will calculate the fee according to the actual weight of the meal picked up, and display it in real time through the display module 6. It should be noted that at this time, regardless of whether the user puts back the meal picking tool 4, the amount displayed at this time is the weight of the meal picking tool 4, and only the price of the dish is accurately measured.

[0040] After the user finishes taking the meal and puts the meal taking tool 4 back into the plate holding slot 3, the position detection mechanism can detect that the meal taking tool 4 has been put back, and the weight of the dining stove will change again. The processor can combine the position status of the meal taking tool and the weight change data of the dining stove to recognize that the meal taking tool 4 has been put back, and the corresponding price data will not change due to the weight change.

[0041] During the entire meal-picking process, the status of the meal-picking tool 4 can be intelligently detected, and the actual price display can be processed accordingly according to the position status of the meal-picking tool 4, so that the actual price display data always excludes the weight of the meal-picking tool 4, so that the price data seen by the user is only related to the actual weight of the dish, realizing real-time and accurate feedback on the weight and price of the dish, thereby improving the user experience and the overall efficiency of the buffet service.

[0042] In general, the processor will automatically detect data and algorithm logic, quickly and accurately obtain accurate dish weight information, and convert the preset meal pick-up tool 4 weight and dish weight unit price into equivalent amount to obtain corresponding price information. It simplifies the originally cumbersome meal pick-up process, effectively reduces the user's operation steps when picking up food at the buffet, allowing users to focus more on the selection and process of dishes, comprehensively improving the user's experience and satisfaction in the buffet scene, and making the entire meal pick-up process more convenient, efficient and enjoyable.

[0043] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
