摘要
针对公安跨区域室外追逃行动的实际的需求,提出了一种新的基于蓝牙技术的便携式指纹追捕系统构架。设计了以AT77C102B和ARM9芯片为核心的传感器节点的硬件,以指纹识别系统为核心的软件。实现了一个基于蓝牙技术的指纹追捕的任务系统平台,经试验结果证明基于蓝牙技术的终端传输的距离能达到70 m,存储的指纹图像的容量能达到40 GB,指纹图像的误检率只有千分之一。
To meet the requirements of cross-regional outdoor pursuit of the policemen, a novel platform framework for Portable Fingerprint Persuit System was proposed based on bluetooth. The hardware of sen- sor nodes and sink nodes are based on AT77C102B and ARM9 and the software is based on embedding real- Fingerprint Identification System. Ultimately,an Portable Fingerprint Persuit System based Bluetooth task system platform was achieved. The test results prove that Bluetooth-based terminal transmission distance can reach 70 m, storage of fingerprint images to achieve the capacity of 40 GB, fingerprint images seized in error rate of 0. 1 percent only.
