Canteen consuming management system design based on CAN bus and Radio Frequency Identification

At present the advanced technology expensing is used mostly in the management system of canteen in the domestic and foreign. The technologies are contacting IC card, the non-contacting IC card and the RS485 bus. But this kind of expensing management system also has some shortcomings. The shortcomings include the slow reading speed, damage, bad secrecy and slow transmission speed and so on. In order to solve the above questions intelligent expensing and management system of canteen based on CAN bus and the wireless radio frequency technology is designed in the paper.This article mainly introduces employment of Radio Frequency Identification (RFID) card reader module ZLG500A and CAN bus in canteen consuming management system design. It describes the hardware and software design in canteen consuming intelligent management system.
