Abstract
The utility model provides a wireless fingerprint recognition system and aims to overcome the defect of difficulty in wiring at positions with bad terrain environment existing in an attendance machine for transmitting acquired data in a wiring manner. The wireless fingerprint recognition system comprises at least one fingerprint acquisition wireless transmitting module, a wireless data receiving module and a PC (Personal Computer); a VFDA02 fingerprint recognition module which are connected with an expansion I/O (Input/Output) interface of a single chip microcomputer AT89C51RC2 through a RS-232 interface; after the acquired data is transmitted to the single chip microcomputer to be processed, the single chip microcomputer controls a PTR2000+ wireless transmitting module connected with the expansion I/O (Input/output) interface of the single chip microcomputer to transmit the acquired data to the PTR2000+ wireless transmission module at the end of the PC through a wireless network, and another PTR2000+ wireless transmission module is connected with the PC through the RS-232 interface to transmit the received acquired data to the PC.
Description
Technical field
The utility model relates to electronic technology field, and a kind of wireless fingerprint recognition system is provided.
Background technology
Now an important component part of enterprise, career management is exactly its occurrences in human life system of attendance, and its quality is the economical, societal benefits of the unit of having influence on and many aspects such as wages of employee directly.Therefore, to the employee's of unit the situation of turning out for work carry out effectively, scientifically management has become the important topic that each unit faces.
Birth along with this advanced computers Work attendance management system of fingerprint attendance system; Examine the feelings problem though solved unit; But existing off line type attendance recorder product all is to couple together through netting twine and supervisory computer when work attendance information is added up; Thereby just requiring has a supervisory computer near the work attendance place, and bothers very much for the bad place laying-out of physical features.And mostly existing work attendance is that USB interface is connected the realization communication with computing machine, and the computing machine USB interface is often very limited.
The utility model content
The purpose of the utility model is to provide a kind of wireless transmission to realize examining the wireless fingerprint recognition system of feelings information uploading to terminal.
The utility model is for realizing that above-mentioned purpose adopts following technical scheme:
A kind of wireless fingerprint recognition system is characterized in that: comprise at least one fingerprint collecting wireless sending module, wireless data receiver module, PC;
Said fingerprint collecting wireless sending module comprises single chip computer AT 89C51RC2; The FLASH flash memory of the VFDA02 fingerprint identification module that is connected with single chip computer AT 89C51RC2, power module, PTR2000+ wireless transport module, keyboard, 32K, real-time clock module and LCD display module; Said VFDA02 fingerprint identification module is connected with the expansion I/O interface of single chip computer AT 89C51RC2 through RS-232 interface; After the data that collect were passed to single-chip microcomputer and handle, the PTR2000+ wireless transport module that Single-chip Controlling is connected with its expansion I/O interface sent the data that collect to the PTR2000+ wireless transport module of PC end through wireless network;
Said wireless data receiver module comprises the PTR2000+ wireless transport module, and it is connected with PC through RS-232 interface, sends the image data that receives to PC.
