摘要
针对航油油罐采样阀身份认证管理困难的情况,设计了一种基于指纹识别的智能型采样阀。以TMS320VC5509A型DSP芯片作为核心处理器,介绍了硬件组成和软件结构,并简要说明了指纹识别的具体算法。经过实验测试,各项指标满足实际应用的需求,具有良好的市场前景。
In order to overcome the management difficulty in identity recognition to the sampling valve of fuel tank, a kind of intelligent sampling valve was designed based on fingerprint identification. TMS320VC5509A type DSP chip was chosen as the core processor. The hardware and software structures were described. A brief description of the specific algorithm for fingerprint recognition was introduced. The experimental testing shows all kinds of technical indexes meet the needs of practical applications. This kind of intelligent sampling valve may have a good market prospects.
