Electronic Code Lock advantages: simple hardware structure, feature-rich, using SCM to realize the electronic code lock, to follow in the design of the software instead of hardware, software can use the hardware to do the things to do, and can not change the hardware case, the corresponding software changes, different functions derived products; password combination more safety, convenience. With the advent of single chip, there has been smart with microprocessor lock, except it has the electronic code lock function, but also the introduction of intelligent management, expert analysis system and other functions, so that the lock with high security and reliability. At present, China developed electronic lock technology is still relatively backward, the development of electronic locks they use a separate electronic components or the common digital circuit design and production, although compared with the mechanical key lock has many advantages, but the low level of intelligence, coding combination is still small. The digital clock is a single chip to do (AT89C51) as the core, combined with the components (digital and matrix keys, etc.), which together with the corresponding software, to achieve the purpose of making simple password, the difficulty lies in hardware components selection, layout and subsequent debugging.
