Currently use a wide range of electronic locks, distinctive, the design from the point of view, for the control of the 80C51 microcontroller core, developed an electronic lock. The design of the hardware part is simple smallest single-chip system, through programming, to achieve its electronic code lock function The lock design is reasonable, simple, low cost, in line with re- sidential, office with a lock request, the promotion of a certain value KEYWORDS：code-lock；Single Chip Micro-Computer 目 录 1 密码锁设计课题任务、功能要求说明及总体方案介绍··················1 1.1 密码锁课题任务及功能要求··································1 1.2 密码锁设计总体方案介绍及工作原理说明······················1 2 密码锁硬件系统的设计···········································2 2.1 密码锁硬件系统各模块功能简要介绍··························2 2.2 密码锁电路原理图、PCB图、元器件布局图各1份··············2 2.3 密码锁元器件清单··········································2 3 密码锁软件系统的设计··········································3 3.1 密码锁设计使用单片机资源的情况···························3 3.2 密码锁设计软件系统各模块功能简要介绍及流程图··
