Technical Field

[0001] This invention relates to the field of smart catering information technology, and in particular to an intensive smart canteen meal supply monitoring and management method and device. Background Technology

[0002] Smart canteens are a new dining model developed based on information technologies such as the Internet of Things and big data. Their primary service targets typically include large organizations, hospitals, and schools. Due to the large number of diners and complex dining needs in these institutions, new challenges arise in improving canteen operational efficiency, reducing labor costs, and optimizing the dining experience. By combining with intelligent hardware and software systems, new smart canteens are gradually reshaping the traditional dining experience. Diners not only expect a pleasant dining experience but also hope to improve their health. Current smart canteen management is relatively rudimentary, lacking quantitative feedback management of food quantity and quality, and failing to monitor food waste throughout the entire process. Therefore, there is an urgent need for an intensive smart canteen food supply monitoring and management method and its associated devices. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an intensive smart canteen meal supply monitoring and management method and device to address the shortcomings of the existing technology.

[0004] The technical problem to be solved by this invention is achieved through the following technical solution: an intensive smart canteen meal supply monitoring and management method, comprising the following steps: Step S1, diners confirm their self-ordered meals through a health assistant digital system; Step S2, the system performs facial recognition on diners at the entrance, and the meal supply system transmits personnel information to obtain the type and quantity of dishes to be picked up, and prepares the meals in advance; Step S3, the facial recognition information of diners is matched with the RFID tag information of the current plate, and diners take the tray with the matched information; Step S4, after the tray is placed in the food pick-up slot, the meal supply system identifies the RFID tag information of the placed tray, and then automatically places the confirmed dishes into the tray; Step S5, after finishing their meal, diners call the recycling device at their seats, place the tray in the recycling device, and leave, thereby performing an automatic weighing and statistics and tableware recycling process.

[0005] Furthermore, the judgment process in step S1 includes the process of automatic ordering and / or manual ordering through the health assistant digital system.

[0006] Furthermore, the automatic ordering process includes the system comprehensively judging the types and quantities of dishes that the corresponding person should receive based on the rules, and generating the above information as RFID pre-written information.

[0007] Furthermore, the comprehensive judgment rules for the automatic ordering process include the system randomly selecting a menu combination based on all the dishes available that day, and selecting the corresponding quantity of each dish based on the menu combination and personal information with the goal of nutritional balance. The personal information includes age, occupation, weight, blood sugar and blood lipid information.

[0008] Furthermore, the manual ordering process included in step 1 includes the process of diners ordering food independently through the health assistant digital system applet. Diners pre-select their food, and the system provides corresponding nutritional suggestions for the current dishes during the ordering process. After selecting the dishes, diners select the recommended portion size from the system.

[0009] Furthermore, the process of automatic and / or manual ordering by the health assistant digital system includes two methods for adjusting the amount of food. One is to compare the average amount of food ordered in a single meal in the previous period with the total amount of food selected this time, and give a recommended value for the amount of each dish corresponding to the total amount of food this time. The other is to apply a percentage discount to the amount of food wasted in the previous meal that exceeded the set weight.

[0010] This invention also discloses an intensive smart canteen food recycling device, specifically including a base, a lifting system, a weighing and lifting device, an identification device, and a rotary drive mechanism. The base has a walking mechanism at its bottom, and a swill bucket and a tray bucket are respectively located on the front and rear sides of the base. The lifting system includes a pair of sliding rods and a sliding seat. The top of the sliding seat is equipped with an identification device for identification. The weighing and lifting device is installed at the front of the sliding seat through the rotary drive mechanism. A tray is placed on the weighing and lifting device, and a bowl is placed on the tray.

[0011] Furthermore, the slide block has sliding holes on both sides that are slidably engaged with the slide rod, and anti-jamming rollers are provided inside the sliding holes. The top of the slide rod is provided with a motor drum mechanism, and the slide block is connected to a pull rope for driving the motor drum mechanism.

[0012] Furthermore, the weighing and lifting device includes a first tray and a second tray, and the rotary drive mechanism includes a motor drive shaft. Both the first tray and the second tray are connected to the motor drive shaft to achieve rotary drive. The upper part of the first tray is provided with a holding groove, and the rear side of the holding groove is provided with a transition slope.

[0013] Furthermore, the bottom of the first tray is provided with a pair of distance sensors for detecting the relative position of the first tray and the second tray, the upper part of the second tray is provided with an electronic weighing device, and the middle of the holding slot is provided with a through opening for accommodating the electronic weighing device to contact the tray.

[0014] Compared with the prior art, the present invention has the following advantages: (1) The present invention alternates between automatic and manual ordering. Automatic ordering does not require manual selection, which improves ordering efficiency and ensures nutritional balance. Manual ordering ensures personalized dining needs and improves the enthusiasm of diners. Both methods can provide food quantity correction based on historical dining data to reduce waste. Symbolic punishment feedback can be given on food quantity based on the degree of waste. The closed-loop information feedback improves the awareness of saving. (2) The present invention separates the tray from the weighing device, which can avoid contamination of the weighing part and improve the weighing accuracy. At the same time, the split structure cleverly realizes the rear flip-top tilting movement, achieving a self-cleaning effect. Through the continuous meal collection process, it reduces the inconvenience of manual meal collection or delivery of trays and the occurrence of queuing. (3) This invention can record information through label recognition, realize digital management of dining, optimize the health management of diners through the correction of the amount of food ordered, and improve the digital efficiency of long-term management through the digital assistant.

Detailed Implementation

[0016] 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.

[0017] As shown in the appendix of Embodiment 1 of the present invention Figure 1-4As shown, this invention discloses an intensive smart canteen meal supply monitoring and management method, including the following steps: Step S1, diners confirm their self-ordered meals through a health assistant digital system; Step S2, the system performs facial recognition on diners at the entrance, and the meal supply system transmits personnel information to obtain the type and quantity of dishes to be picked up, and prepares the meals in advance; Step S3, the facial recognition information of diners is matched with the RFID tag information of the current plate, and diners take the tray 7 with the matched information; Step S4, after the tray 7 is placed in the food pick-up slot, the meal supply system identifies the RFID tag information of the tray 7, and then automatically places the selected dishes into the tray 7; Step S5, after finishing their meal, diners call the recycling device at their seats, place the tray 7 in the recycling device, and leave, thereby performing an automatic weighing and statistics and tableware recycling process.

[0018] The judgment process in step S1 includes automatic and / or manual ordering via a health assistant digital system. The automatic ordering process includes the system using comprehensive judgment rules to determine the types and quantities of dishes the individual should receive, and generating this information as pre-written RFID information. The comprehensive judgment rules for the automatic ordering process include the system randomly selecting a menu combination from all available dishes for the day, and selecting the quantity of each dish based on the menu combination and the individual's personal information, including age, occupation, weight, blood sugar, and blood lipid information, with the goal of nutritional balance.

[0019] The manual ordering process included in step 1 includes the process of diners ordering food independently through the health assistant digital system applet. Diners pre-select their food, and the system provides nutritional suggestions for the current dishes during the selection process. After selecting the dishes, diners select the recommended portion size from the system.

[0020] The health assistant digital system's process of automatic and / or manual ordering includes two methods: system quantity adjustment and a method for adjusting the amount of food ordered. First, it compares the average amount of food ordered per meal in the previous period with the total amount of food selected this time, providing a recommended amount for each dish corresponding to the total amount of food ordered. Second, it applies a percentage-based discount to the amount of food wasted in the previous meal if it exceeded a set weight. Thus, this invention allows for alternating automatic and manual ordering. Automatic ordering reduces selection difficulties while ensuring nutritional balance and improving dining efficiency. Manual ordering ensures personalized dining needs and increases dining enthusiasm. Both methods can adjust the amount of food ordered based on historical dining data to avoid excessive waste. Furthermore, symbolic penalties based on the degree of waste help form a closed-loop information feedback system, while also improving the health awareness and conservation awareness of diners in the green and smart canteen.

[0021] This invention also discloses an intensive smart canteen food recycling device, specifically including a base 1, a lifting system 2, a weighing and lifting device 3, an identification device 4, and a rotary drive mechanism 5.

The lifting system 2 includes a pair of sliding rods 21 and a sliding seat 22. The sliding seat 22 has sliding holes on both sides that are slidably connected to the sliding rods 21. Anti-jamming rollers are provided inside the sliding holes. The top of each sliding rod 21 is provided with a motor drum mechanism. The sliding seat 22 is connected to a pull rope for driving the motor drum mechanism.

[0022] The top of the slide 22 is equipped with an identification device 4 for identity recognition. The weighing and lifting device 3 is installed at the front of the slide 22 via a rotary drive mechanism 5. A tray 7 is placed on the weighing and lifting device 3, and a bowl 71 is placed on the tray 7. Specifically, the weighing and lifting device 3 includes a first tray 31 and a second tray 32. The rotary drive mechanism 5 includes a motor drive shaft. Both the first tray 31 and the second tray 32 are connected to the motor drive shaft to achieve rotational drive. The upper part of the first tray 31 is provided with a holding groove, and the rear side of the holding groove is provided with a transition slope. The bottom of the first tray 31 is provided with a pair of distance sensors 6 for detecting the relative position of the first tray 31 and the second tray 32. The upper part of the second tray 32 is provided with an electronic weighing device 33. The middle of the holding groove is provided with a through-hole for accommodating the electronic weighing device 33 in contact with the tray 7. Through the above-mentioned environmentally friendly recycling system, not only can one call the recycling robot after finishing the meal and place the tray in before leaving, but automatic weighing can also be performed. This process can also include emptying the food to store the tableware separately. This device can be regarded as a robotic food collection device, which can collect food continuously. It reduces the time and labor costs of manual food collection, the difficulty of information processing, and avoids the inconvenience of diners bringing their trays and the phenomenon of queuing.

[0023] Therefore, in practical applications, this invention employs a health assistant digital ordering system for both automatic (based on past performance) and manual ordering, selecting the appropriate method as needed. Each method includes health and nutrition recommendations and waste monitoring, enabling comprehensive information-based self-management throughout the entire process and improving diners' self-awareness and the level of food health management. In summary, this invention allows for system-based pre-ordering, portioning meals according to individual appetite sizes to reduce food waste; ordering based on personal appetite and taste, with automatic meal preparation and contactless payment; and automatic food recycling to weigh leftover food, recording any exceeding a set value and the amount consumed each time, thus reducing food waste in the slop buckets.

[0024] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
