Description
Technical Field
The invention relates to the field of canteen expense settlement and management, in particular to a school canteen intelligent settlement and dining information management system and a management method thereof.
Background
At present, most of the catering of school canteens are carried out by dinning room staff on a dish serving workbench in an interactive way with students, and the students often arrange long teams to select meals and wait for card swiping settlement during the peak dining period. Because of the lack of intelligent equipment, the current cost calculation mode mainly depends on manual work, basically, dish samples in the dinner plate are manually observed and added and settled one by one according to prices, and the settlement mode is not only slow, but also has higher error rate under the condition that the varieties of dishes are more. In addition, at present, school students lack management on diet consumption conditions in schools, and parents and teachers have no knowledge about whether students consume in canteens or not and about diet structures and the like. In order to pursue efficiency and take care of physical health of students, the old mode of food supply and consumption management is urgently required to be improved.
Therefore, with the development of science and technology, some intelligent dining management systems are provided in the prior art, such as the chinese patent of the publication No. CN 105205922B: an intelligent settlement and consumption information management system for canteens in colleges and universities is composed of an intelligent settlement subsystem and a consumption information management subsystem; the intelligent settlement subsystem consists of a canteen settlement operating platform, tableware with RFID tags, a tray sliding channel and an intelligent settlement terminal; the consumption information management subsystem is composed of a general server, a base station and a receiving end. Although the intellectuality of dining room settlement and management has been promoted to a certain extent, the dining room mode of its application mainly holds good operation mode for the dish, and its dish has the heat preservation problem in winter to need a large amount of RFID label's tableware, and then increased system operation cost and the price modulation is loaded down with trivial details, also brought the puzzlement to the clean tableware of dining room staff. In addition, the prior art also adopts an image recognition technology, adopts the dinner plate color classification for pricing or directly recognizes the dish picture for pricing, and the like, but has some defects. If the dish picture identification mode can easily cause the false identification condition along with different dish components and firing processes, the dish color classification can only count the price but can not count the type information of the dishes for dinner, the change cost of the existing intelligent scheme is higher, and the method has greater examination on the fund use of the existing school. According to the intelligent balance management system, consumption balance intelligentization is realized through the intelligent balance subsystem, students, school parties and canteen managers can conveniently inquire diet consumption conditions of the students through the consumption information management subsystem, and the school parties and the canteen managers can inquire sales conditions of various dishes, so that the management of the canteen is facilitated, and resources are saved.
