Cash Register Control System And Coins Identification Method Development

The object designed a kind of cash count and cash check control system for a specific money machine which is based on the processor (AT89S52). Counting control system uses a variety of methods to identify counterfeit paper currency, which greatly improved the flexibility of machine use and_improved the ability to identify real and counterfeit of cash. The entire system is composed by data acquisition subsystem, data processing and control subsystem, the motor drive subsystem three parts from the functional. The data acquisition subsystem sent the data that are fluorescent, ultraviolet, infrared penetration, the count signal, to the data processing and control subsystem, the task of data processing and control subsystem is to detect the money real and counterfeit, the motor drive subsystem drives actuators action according to the data processed.Working of researching on cash-counting machine for a particular one:Currency counter structural composition and principles and the overall design of the control system were introduced. According to a variety of unique characteristics on cash, ultraviolet, infrared, magnetic security lines were used to precisely recognition real and false of paper money. Hardware circuit were design, PCB board were drawn and a circuit board production and the initial hardware debugging were completed. Do software development and debugging. The modular thinking of software design facilitate future remodeling and expansion.
