Abstract: According to the status that low density of integration for sampling in the finger vein identification system，collection control card based on the universal serial BUS interface is developed.This collection control panel achieves the function including light controlling，finger positioning，automatic parameter adjustment，and collection and transmission of finger vein image.The collection control panel including structure，working principle and intelligent parameters adjustment algorithm based on fuzzy control and multi-sensor fusion is discussed in detail.Practical application shows that the collection device which installation this plate can be more accurate to obtain veins images，has good portability and application.

Key words: finger vein recognition, sample device, universal serial BUS, fuzzy control

摘要： 针对手指静脉识别系统中样本采集装置集成度低的现状，研制出一种基于通用串行总线（USB）接口的采集控制板，实现采集装置的光源控制、手指定位、自动参数调整和手指静脉图像的采集、传输。详细讨论了采集控制板的结构组成、工作原理以及基于模糊控制的智能参数调整算法。实际应用表明，安装该板的采集装置能够较为准确地获取静脉血管图像，具有较好的便携性和应用性。
