数字电子密码锁

Digital Electronic Code Lock

针对传统的机械锁的各种缺点和重要部门安全性要求,提出一种基于数字电子技术的密码锁核心电路设计方案,通过此方案设计的密码锁电路不但满足安全性要求,也能够适应特殊环境的使用需求。触发式电子密码锁的设计制作主要应用了数字电子技术的编、译码技术,并通过按键实现密码的设置、修改及识别功能。设计电路主要由集成芯片编、解码电路,轻触式按钮及显示电路组成。

For the shortcomings of traditional mechanical locks and the demand of important safety departments,a design scheme of digital electrical technique-based password lock is proposed.This design method of the code lock can not only satisfy the requirements,but also adapt to the needs of special environment.The design of burst mode code lock mainly adopts the coding technique and decoding technique of digital electronic technique,through the key to achieve setting,modifying and identifying the passwod.The designed circuit consists of coding and decodeing circuit of integrated chip,touch-button and display circuit.
