Design And Implementation Of Wireless Fingerprint Attendance System

Specifically for the present need of attendance management in enterprises and companies, this paper designs and implements the wireless fingerprint attendance system based on the technology of fingerprint identification and wireless communication, using MCS-51 series microprocessor, the fingerprint identification module FDA02 and the wireless communication module PTR2000+. This device can accomplish the attendance independently and wireless transmission of attendance information. This system makes use of international advanced special use to defend against marking the optics fingerprint identification technology, according to uniqueness and different of everyone fingerprint, invariant characteristic in one's life. It can check on work attendance independent usage of computer. It has big capacity of attendance recordings, the precise time and can send the recordings in immediate, fixed time or the response modes to the managing PC. Managing PC processes the attendance data and completes the demonstration, inquiry and printing the data. This system solves the disadvantage of existing the false checking, person managing, low efficiency in the traditional attendance machine and has the extremely widespread application prospect.This article in detail introduces this system's design process, mainly dividing into following several parts:First, introduced the fingerprint recognition classification and its principle and the characteristic, as well as based on fingerprint identification technology correlation application. At present had the fingerprint checking attendance machine type and its superior, the shortcoming contrast.Second, introduced this system overall frame design and the function which it has.Third, in detail introduced this system hardware design and the realization process, and produce the main hardware unit circuit design the schematic diagram and its the PCB board design method, simultaneously in detail has also produced its hardware welding, the debugging process.Fourth, according to chooses the plan and this system characteristic compiles its software system, and separately to systems controlling software, the application software as well as the communication agreement has carried on a more detailed analysis and the explanation, and finally has produced the main module concrete realization process.
