随着电子产品向智能化和微型化的不断发展,单片机已成为电子产品研制和开发中首选的控制器。为了更好地推广单片机在家电领域中的应用,介绍了一种应用AT89C2051单片机设计的电子密码锁。经实验验证该密码锁具有安全、实用、成本低等特点,符合住宅用锁的要求,可作为产品进行开发。

As electronic products are developing towards intelligence and minimization, singlechip computers (SCM) have become the first choice for controllers in the development of electronic products. In order to expand the applications of SCM into household appliances, a new designing method of electronic cipher locks by the use of AT89C2051 singlechip processor is introduced in this paper. Experiments show that the designed cipher lock is characterized by its low cost and high degree of safety and practicality. Besides, it works well as a residence lock and has great potential for commercial development.
