摘要
系统设计主要以AT89S52单片机为核心,利用单片机的串行通信原理,实现对其他硬件的精准控制,共同达到以语音密码解开电子锁。其中LD3320模块负责生物语音密码的识别验证,将生物特征(声音)作为一种输入信号,用程序将生物声音存于硬件内部,之后将获取的信号与存储的信号相比较,达到开关锁的功能。此外还有传统的矩阵键盘密码输入控制。两种方式错误都会有蜂鸣器报警。系统易操作,且稳定性高,可扩展性强,方便后期进一步开发。
The system design mainly takes the AT89 S52 single-chip microcomputer as the core, and realizes the precise control of other hardware by using the serial communication principle of the single-chip microcomputer, and jointly unlocks the electronic lock with the voice password. The LD3320 module is responsible for the identification and verification of the bio-voice password. The bio-feature(sound) is used as an input signal, and the bio-sound is stored in the hardware by the program, and then the acquired signal is compared with the stored signal to achieve the function of the switch lock. There is also a traditional matrix keyboard password input control. There are buzzer alarms for both modes of error. The system is easy to operate, and has high stability and scalability, which is convenient for further development in the later stage.
