ARM7-based Wireless Fingerprint Attendance Eqiupment Research And Implementation

In recent years, with the fingerprint recognition technology and wireless technologydevelopment, China’s enterprises attendance management needs, but the current fingerprintattendance system using a small-scale attendance, small crowd attendance, non-real-timeand attendance and other issues. And traditional attendance different wireless fingerprintattendance recognition speed, and convenient network structures, can effectively identifyuser identity. In this paper, the existing wireless technologies and attendance system wasanalyzed, proposed ARM7-based wireless fingerprint time attendance devices, and as abasis for the system and its implementation.Firstly, combined with college requirements, the system’s overall program accordingto the main function of the hardware selection and design of hardware schematics anddrawing PCB, on this basis for the overall design of the various specific functions carriedout a detailed design.Secondly, this paper focuses on description of the wireless fingerprint attendancedevice lower computer program design ideas, as well as in the software developmentprocess problems and propose solutions for WIFI wireless technology and touch screenprinciple depth study proposes WIFI transport protocol design of the program, makes thesystem more secrecy; touch screen touch area division method and touch operation wasproposed to make a more convenient time and attendance equipment and more flexibility.Finally, the system has been used repeatedly and continuously improve the basiccompletion of the fingerprint identification, time and attendance data to attendance datatransmission functions described herein ARM7-based wireless fingerprint time attendancedevice is feasible.
