摘要
介绍了一种基于DSP和MCU的双片结构的无线指纹识别系统的设计实现。系统由AES2510和TMS320VC5507构成指纹图像采集模块,由PIC18LF4620和MRF24J40构成基于Zig-Bee网络的指纹认证信息的无线传输模块。该系统相对传统的嵌入式指纹识别系统更适合于人员多和指纹采集地点发散的场合,可以作为大型考勤系统的一种解决方案。
This paper presentation the design and implementation of the wireless fingerprint identification system by a DSP and MCU based on the two - piece structure. The system is composed of fingerprint sensor AES2510 with DSP （TMS320VC5507） as the fingerprint image acquisition module and PIC18LF4620 with MRF24J40 as the fingerprint authentication information wireless module based on ZigBee network. As to traditional embedded fingerprint identification system, the system is more suitable for more staff and fingerprint collection sites divergence＇ s occasions. The system is suitable for a large - scale checking system＇ s solution.
