Abstract

The utility model relates to a radio frequency identification (RFID) attendance management system, which comprises a main control device, an RFID attendance reader-writer and an RFID attendance electronic label, wherein the RFID attendance reader-writer comprises a coupling module, a high-frequency module, a control module, signal shielding equipment and an antenna; the RFID attendance electronic label comprises a coupling module and a storage chip; the signal shielding equipment of the RFID attendance reader-writer is a groove-shaped shell and wraps the RFID attendance reader-writer, so that the RFID attendance reader-writer can only send a radio frequency signal to a groove opening direction and receive the radio frequency signal from the groove opening direction; get-in and get-out states of students can be quickly identified according to a time sequence of receiving the signals by a group of two RFID attendance reader-writers; and the main control device quickly counts an attendance situation of the students according to information acquired by the RFID attendance reader-writers, records the get-in and get-out time and the stay time of the students in different places in real time and supplies convenience to effective recording and management of various activities of the students.

Description

RFID attendance management device

Technical field

The utility model relates to the RFID infotech, specially refers to a kind of RFID attendance management device.

Background technology

Radio-frequency (RF) identification is RFID(Radio Frequency IDentification) technology, claim electronic tag, radio frequency identification again, it is a kind of communication technology, can identify specific objective and read and write related data by radio signals, and need not to set up machinery between recognition device and the specific objective or optics contacts.

The RFID electronic tag has cheap, volume is small and exquisite, RFID tag can be stored information and the certain information processing function of tool of a constant volume, read-write equipment can be by radio signals with certain data transmission rate and label exchange message, and operating distance can not wait from some centimetres to 1 km according to the technology that adopts.The basic functional principle of RFID electronic tag is, after label enters magnetic field, receives the radiofrequency signal that read write line sends, and the energy that relies on induction current to obtain sends out the information that is stored in the chip.Read write line is delivered to the processing that master control set carries out relevant data after receiving information and decoding.

At present, in school, the student can be by gate inhibition card or other perfect instruments different places such as classrooms, library, dormitory of coming in and going out, and different students has different authorities, can freely come in and go out in the time that allows.But gate inhibition card or perfect instrument can't be identified the student and enter or go out, and can't record the time that the student stops in a certain place, if the mode by manual record then labor intensive material resources, and efficient is very low.

Simultaneously, present student's work attendance statistics is as work attendance on class, stay statistics, Visitor Logs etc., usually adopt artificial roll-call, pattern register, waste time and energy, and be difficult to statistics during large contingent, the activity of student in the different places of school lacked effective and practical management.

Therefore, there is defective in prior art, needs further improvement and develops.

Summary of the invention

The purpose of this utility model provides a kind of student's attendance management device, and it can identify the turnover state of the RFID work attendance electronic tag that passes through fast, and the service of express statistic student attendance is provided, and makes things convenient for record and the management work of student attendance.

To achieve these goals, the utility model adopts following technical scheme:

RFID attendance management device, comprise master control set, RFID work attendance read write line and RFID work attendance electronic tag, wherein, RFID work attendance read write line comprises coupling module, high-frequency model, control module, signal shielding equipment and antenna, and RFID work attendance electronic tag comprises coupling module and storage chip.

Described RFID attendance management device, wherein, the signal shielding equipment of described RFID work attendance read write line is groove shape shell, is wrapped in RFID work attendance read write line outside.

Described RFID attendance management device, wherein, the high-frequency model of described RFID work attendance read write line comprises transmitter and receiver.

Described RFID attendance management device, wherein, the storage chip of described RFID work attendance electronic tag is the FLASH storage chip.

The RFID attendance management device that the utility model provides, by two RFID work attendance read write lines that are installed in each place, building gateway, identify student's turnover state fast, the information express statistic student that master control set is collected by the RFID work attendance read write line situation of turning out for work, real-time record student is in access time and the residence time in different places, for the Activities of effectively recording, manage the student facilitate.

Description of drawings

Fig. 1 is the structural representation of the utility model RFID attendance management device;

Fig. 2 is the synoptic diagram of the utility model RFID work attendance read write line signal shielding equipment;

Fig. 3 is that the utility model RFID attendance management device cognometrics bears the synoptic diagram into state.

Embodiment

Below in conjunction with preferred embodiment the utility model is described in further details.

RFID attendance management device of the present utility model, comprise master control set, RFID work attendance read write line and RFID work attendance electronic tag, RFID work attendance read write line comprises coupling module, high-frequency model, control module, signal shielding equipment and antenna, and RFID work attendance electronic tag comprises coupling module and storage chip.

Per two of RFID work attendance read write line is one group of place, gateway that is installed in building, signal shielding equipment is groove shape shell, be wrapped in RFID work attendance read write line outside, make that RFID work attendance read write line only can send to the slot opening direction, received RF signal, RFID work attendance read write line sends radiofrequency signal by transmitter and the antenna of coupling module, high-frequency model.

The student wears RFID work attendance electronic tag with oneself, and student's personal information storage is in storage chip, and RFID work attendance electronic tag sends the radiofrequency signal that comprises personal information after entering the magnetic field that RFID work attendance read write line launches by coupling module; Described storage chip can be the FLASH storage chip.

RFID work attendance read write line is by the receiver received RF signal of high-frequency model, the signal that receives by control module decoding, the time sequencing that receives signal by two read write lines is judged this RFID work attendance electronic tag and is entered or go out, RFID work attendance read write line sends to the information that reads in the master control set, note time and the state that RFID work attendance electronic tag passes in and out by master control set, described memory module can be the FLASH storage chip.

The work attendance situation that can add up the student rapidly by master control set is by the information that master control set is obtained, the tissue of science, planning student's Activities more.

First preferred embodiment of described RFID attendance management device, RFID attendance management device comprises master control set, RFID work attendance read write line and RFID work attendance electronic tag, RFID work attendance read write line comprises coupling module, high-frequency model, control module, signal shielding equipment and antenna, RFID work attendance electronic tag comprises coupling module and storage chip, as shown in Figure 1.
