| The fingerprint consultation is one of the most important means that the Human body identifies. Currently, the fingerprint identifies positive facing of technique small scaled turn to develop with built-in direction. The fingerprint of the Qian person’s type identifies system is collect Be gathered to the single machine system of whole body, can do with processing very small, suit to used for guarding against theft door, upscale car door and company to test very much frequently system etc. Qian person type situation.This text designed to check inside the adoption ARM7the S3C44BO X processor in order to control unit, take to have the USB2.0the fingerprint for connecting a people’s technique to collect system. The design that wove two big mold pieces of distances to in detail introduce the whole system from the hardware design and the software. First, lead to go into a fingerprint to collect realm and replace the single slice of machine of tradition to carry on a hardware system design currently the popular ARM technique, use Protel the99SEs draw to develop plank principle diagram. Then, adoption currently popular USB communication mode, used USB to connect a people’s full speed to deliver a fingerprint data, not only promoted a data to deliver speed, and very convenient during the period of physically applying, saved much precious time expense for the identifying of follow-up fingerprint work at the same time.From the privately owned research conclusion up see, the system has very strong function and well embodied the strong control abilities of ARM and the high speed of USB to deliver. What to have to put forward BE, the system still keeps being placed in an initial development to study a stage. The system only carried out the initial development that the fingerprint collects soft hardware and left the actual application that the end fingerprint identifies aspect to still have a distance, and many works want to do. |
