摘要
针对目前市面上已有的指纹锁、人脸锁等,尚且缺乏一款成熟的语音锁,设计并实现了一种利用不同说话人声音之间的差异,而识别开锁人身份的智能语音门锁系统。系统以智能手机为客户端平台,采集用户的语音,上传至云服务器,利用声纹识别技术识别用户身份,当用户通过身份认证,系统再通过无线网络通信的方式,将开锁信号发送到以NodeMCU为硬件平台的门锁端,从而实现开锁操作。此外,系统采用Web网页的形式展示服务端后台,可以实现管理员对系统的远程管理和监控。实验结果表明,该门锁系统的具有90%左右的识别准确率,同时错误接受率较低,充分证明了系统的安全性和稳定性。
As the existing fingerprint locks and face locks on the market, there is still a lack of a mature voice lock, and a smart voice lock system that uses the difference between different speaker voices to identify the unlocked person is designed and implemented. The system uses the smart phone as the client platform, collects the user’s voice, uploads it to the cloud server, and uses the voiceprint recognition technology to identify the user identity. When the user passes the identity authentication, the system sends the unlock signal to the NodeMCU which is the door lock end of the hardware platform through wireless network communication, thereby realizing the unlocking operation. In addition, the system uses the web page to display the server background, which enables the administrator to remotely manage and monitor the system. The experimental results show that the door lock system has a recognition accuracy of about 90%, and the error acceptance rate is very low, which fully proves the safety and stability of the system.
