| Fingerprint recognition technology is a kind of biometric recognition technology.It is the most popular used and the most widely used authentication technologies.For each person’s fingerprint is unique and invariance,compared with traditional digital password identification or bar code recognition, Fingerprint recognition has a higher security. Fingerprint technology is relatively mature, fingerprint identification equipment at home and abroad for attendance, access control, police Criminal Investigation. Now many of the fingerprint recognition system is also based computer or server implementation, having the disadvantage of poor mobility, a large power consumption. In contrast, application of the fingerprint identification system to the embedded device which has good mobility, low power consumption, fast. Therefore the development of embedded fingerprint identification system has broad application prospects.The paper presents the S3C2410embedded hardware platform based on ARM processor architecture. Build entire system embedded environment, ported to the Linux system, hardware platform, and configure the various modules. Build a good software platform. Whole fingerprint recognition system displayed by Qt Designer interface, touchscreen interface not only has the function of the output display, but also the function of the input control. Through signal and slot mechanism with the operating system for communication. Fingerprint recognition module uses USB communication, so this chapter is mainly USB drive design, embedded system through USB drive design and acquisition module good communication, and communication protocol module control. |
