Description

Technical Field

[0001] This invention belongs to the field of smart catering technology, specifically relating to a self-service meal selection machine. Background Technology

[0002] In recent years, with the development of cutting-edge technologies such as the Internet of Things, big data, and cloud computing, intelligentization has become a new trend in all walks of life; smart canteens are among them, and the scale of smart canteens has now exceeded 100 billion yuan. Smart canteens can realize unmanned self-service dining. Diners enter their information into the smart canteen system through facial recognition, and then order food at the self-service ordering machine. The self-service ordering machine identifies the diner's information through the chip on the plate, and identifies the food taken by weight or image acquisition when picking up the food, and the system settles the bill.

[0003] Self-service meal machines typically have a food placement area and a tray sensor area. Diners take food from the food placement area and place it on their trays. However, staff have observed some uncivilized dining behaviors during daily meals, such as taking too much food or returning unwanted food from their trays to the communal food placement area. This creates a very poor dining experience for other diners and also increases the risk of disease transmission. Summary of the Invention

[0004] This invention provides a self-service meal selection machine equipped with a dining monitoring module and a protective barrier structure. When the monitoring module detects uncivilized dining behavior, the control system activates the protective barrier structure to stop the diners' actions and simultaneously broadcasts a voice reminder. Through monitoring and forced intervention, dining behavior is standardized, avoiding the risk of cross-infection of diseases. This invention solves the problem of the lack of monitoring and intervention mechanisms for food selection on smart dining devices, which leads to some uncivilized dining behaviors.
