摘要
指纹识别技术是通过内部的指纹识别算法和复杂图像分析识别技术形成,通过串口通信协议和控制器组合,在日常生活中得到广泛的应用,特别是在智能家庭、指纹门锁、手机解锁、身份验证及在线支付都能起到非常重要的作用。该文设计的这一款基于物联网的指纹识别系统能够存储100枚指纹,通过内置的指纹库对指纹信息进行持久化存储,并能实现采集录入、增加删除、修改及验证等功能。当指纹连续多次识别失败,提供非法验证报警处理。采用不同颜色的LED灯来标识指纹识别录入、删除及验证状态。通过测试系统性能良好,达到预期的设计效果。
Fingerprint recognition technology is formed by internal fingerprint recognition algorithm and complex image analysis and recognition technology, and is widely used in daily life through the combination of serial port communication protocol and controller, especially in the smart home, fingerprint door lock, mobile phone unlock, identity verification, online payment can play a very important role. The fingerprint identification system based on the internet of things can store 100fingerprints, and the fingerprint information can be stored persistently through the built-in fingerprint database, and can achieve the acquisition of input, increase delete, modify, verification and other functions. When the fingerprint recognition fails for many times continuously, the illegal verification alarm processing is provided. Using different color LED lights to identify fingerprint identification input, delete and verification status. Through the test system performance is good, achieve the expected design effect.
