Abstract

The invention discloses a self-powered finger vein identification system based on electrostatic energy acquisition and belongs to the biological characteristic identification field. The system comprises an electrostatic energy collector, a power supply module, a processor, an infrared light source module, an infrared image collector and a memory. The electrostatic energy collector converts pressure from a finger to be measured into a pulse voltage, outputs to the power supply module and carries out self-power action on the system. The processor sends an instruction to the power supply module so as to control power supply and power failure of the infrared light source module, the infrared image collector and the memory. In one pulse voltage, acquisition and identification of a finger vein image are completed. In the invention, an external wired power supply or an internal cell does not need to provide power for the system, acquisition and identification functions of the finger vein image can be completed only through electric energy generated by the finger to be measured which contacts the electrostatic energy collector, a remarkable energy saving effect is achieved and the system is suitable for a portable finger vein identification apparatus.

Description

technical field [0001] The invention belongs to the field of biological feature identification, in particular to a self-powered finger vein identification system based on electrostatic energy collection. Background technique [0002] With the emphasis on public safety and information security in various countries, biometric technology has gradually integrated into all aspects of people's work and life. Among them, finger vein recognition technology has become a research institution, The focus of business attention. [0003] Compared with other biometric identification methods, finger vein recognition technology has the following advantages: [0004] 1) Higher universality, applicable to a wide range of groups, almost everyone can apply finger vein recognition for identity authentication; [0005] 2) Better uniqueness, according to medical proof, the distribution of finger veins between different people is completely different; [0006] 3) Higher stability, finger vein rec...
