Design of Dynamic Password Electronic Lock Based on STM8L MCU
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.
