基于STM8L单片机的动态密码电子锁设计

Design of Dynamic Password Electronic Lock Based on STM8L MCU

锁具的安全性日益受到人们的重视,而现有的电子锁大都采用静态密码的方式。这种方式存在较大的安全隐患,即密码易被遗忘或盗用。针对这一问题,设计一种采用动态密码方式的电子锁系统。该系统由产生动态密码的智能设备和以单片机作为控制核心的电子锁两部分组成,对锁控制系统进行深入研究。首先根据功能要求进行系统整体设计,在硬件电路设计上,采用单片机STM8L实现超低功耗控制,在软件设计上主要通过对动态密码的匹配与识别实现"一次一密"。经过验证系统能够达到预期目标,且功耗特别低,具有很高的实用价值。

Lock security problem is increasingly valued, but the existing electronic locks mostly use static password mode, which has security risk of password being missed or theft. In order to solve this problem, designs a dynamic password electronic lock system. This system is composed of two core modules： intelligent equipment to generate dynamic password and electronic lock controlled by MCU. Studies the lock system, designs an overall design of the system. Uses STM8 L microcontroller to realize special low-power control in the hardware design.Realizes ＂one password at a time＂ through matching and distinguishing dynamic password in the software design. The system can reach the expected target by test and verification, with special low-power control and with great practical value.
