Design of Lock and Alarm System Based on MCU
Abstract
With the development of the people's living standard science and technology day
by day, how to achieve the security of house, company department, documents and
finance forms, also some personal information are ing important in particular.
For satisfy this request, Password alarm system plays a more important role as the
security guards. With the development of large scale integrated circuit technology,
especially the advent of the microcontroller. Appeared with a microprocessor smart
password lock, which, among alarm system with electronic code function, but also the
introduction of intelligent Guan Li, expert-analysis system and other functions, so that
the password lock with high security, reliability, application increasingly widespread.
Given the current level of technology and the market reception of the degree of
electronic code lock is such mainstream of electronic security products. The article is
about the design electronic code lock based on the MCU. The use of the United States
Atmel Corporation AT89S51 microcontroller as a master chip and the data memory
unit, combined with the external matrix keyboard input, LED digital display, alarm,
unlock and so on, dominated by the C programming language chip EEPROM of
