Tray automatic identification device based on magnetic sensor array

Abstract

The invention discloses a tray automatic identification device based on a magnetic sensor array, and belongs to the field of intelligent catering equipment. The device is composed of a tray with built-in magnetic steels, a checkout counter with a magnetic sensor array, a processor (CPU), a display screen, a payment system, and an additional circuit; the technical problem to be solved is to providea tray automatic identification device based on a magnetic sensor array, a detection array is formed by arranging a plurality of magnetic sensors uniformly on the checkout counter, the magnetic sensors generate trigger signals by setting different numbers of magnetic steels in the bottom of different trays and using a magnetic field generated by the magnetic steels, and due to the different number of built-in magnetic steels, the number of sensors that can be triggered by different trays is different, so as to achieve the purpose of tray automatic identification. According to the tray automatic identification device based on the magnetic sensor array, the work of cashier is replaced by the automatic identification of trays through the checkout counter, which makes the purchase and paymentfaster and more accurate.

Description

technical field [0001] The invention is an automatic identification device for dinner plates based on a magnetic sensor array, which belongs to the field of intelligent catering equipment. Background technique [0002] With the rapid development of information intelligence, smart devices are applied in all aspects of life. For dining places such as school canteens and public canteens of public institutions, consumption settlement basically relies on manual operations, and manual operations are not only slow but also cumbersome. There are cases of operational errors, and it is difficult to meet the current fast-paced and technological life; at present, some companies have made a smart plate system based on RFID identification. This system has relatively complete functions, but it also means that the cost of the system is very high. High, for some small and medium-sized schools and enterprises can not afford the high cost of modification, it is difficult to promote large-scale...
