Access Control System Microcomputer Control Software Design
Abstract: The access control system is only in recent years in the country is another widely used high-tech safety features, has now become one of the hallmarks of modern intelligent building. Access control systems are highly integrated, high security, redundancy rate and other characteristics, to achieve the personnel access permissions settings, but also on storage personnel access date, time, card number and other information; This design uses a single-chip microprocessor technology, the use of advanced technology hardware interface consisting of various circuits, and a detailed analysis of various circuit works, according to the functional requirements of the access control system to write system programs. Program design using a top-down design methodology, the main program module has the main program, subroutines reader, display routines, time to read and write subroutines, open judgment subroutines. Designed to achieve the desired results of an access control system control requirements.
