DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, in order to facilitate a person skilled in the art to easily carry out the technical idea of the present invention.

1 is a conceptual diagram of a smart deposit system according to an embodiment of the present invention.

First, Near Field Communication (NFC) is an extended non-contact wireless local area communication (RFID) technology that does not use a network.

Because Near Field Communication (NFC) can use both data reading and writing functions, it does not require a reader that was previously required for RFID use, and recognizes at a distance of less than 10 cm. When the communication distance is short, And thus it is used as a main technology of the system proposed in the present invention because it has a strong security and excellent convenience.

Near Field Communication (NFC) not only provides data communication in the terminal by converging with mobile devices, especially smart phones, but also provides interoperability with existing RFID. In order to transmit and receive data through Near Field Communication (NFC), the terminal is placed close to the tag and inputs data to the tag. In addition, when the data in the tag is read, the terminal can be read close to the tag and the data stored in the tag.

Also, in the case of communication between two terminals, the terminal may operate in a peer-to-peer manner and perform bidirectional communication, or may use a card emulation mode in which one terminal operates as a tag.

Referring to FIG. 1, a smart attendance system includes an NFC tag 10, a student terminal 100, and an administrator terminal 300.

The student terminal 100 is a general term for a portable device such as a mobile phone, a smart phone, a smart pad, etc., and is assumed to be a terminal composed of a smart phone.

The administrator terminal 300 collectively refers to devices such as a mobile phone, a smart phone, a smart pad, a computer, a desk terminal and the like, and assumes that the terminal is a smart phone or a terminal composed of computers arranged in a class room do.

The NFC tag 10 is placed on each desk in the classroom, and an area where the NFC tag 10 is located is displayed on the desk. For reference, the NFC tag 10 stores classroom information, current seat position information, and a unique number. The information stored in the NFC tag 10 is preferably encrypted.

The student terminal 100 is installed with an application for recognizing the NFC tag 10 placed on the desk in the classroom, and recognizes the NFC tag 10 at predetermined intervals and transmits the recognition state to the manager terminal 300. [ At this time, it is preferable that the application is configured such that it can be installed only in a verified terminal (a terminal officially opened in a communication company) in which a device ID exists.

The administrator terminal 300 adjusts the period of time during which the student terminal 100 recognizes the NFC tag 10 and determines the attendance state, absence state, and departure state based on the recognition result of the NFC tag 10 and displays it.

That is, the application of the student terminal 100 recognizes the NFC tag 10 attached to each desk at intervals set by the manager (professor) in the manager terminal 300, and displays the attendance state / perception state / absent state Thereby determining the state / exit state.

Therefore, the proposed Smart Attendance System can keep the students seated at regular intervals to prevent illegal attendance such as post - attendance and provide accurate attendance status.

The process of operation of the Smart Attendance System is summarized as follows.

First, a user (student) executes an application of the student terminal 100. [ For reference, when the user enters the classroom, the student terminal 100 may automatically be communicated to the portable attendance checker installed at the entrance of the classroom to check whether the classroom is entered, and then the application is automatically executed.

Next, the user places the student terminal 100 on the NFC tag 10 on the desk after sitting in the desired seat.

Next, the application of the student terminal 100 recognizes the NFC tag 10 every predetermined period in the administrator terminal 300, and then feeds the recognition result to the administrator terminal 300. [

Next, the manager terminal 300 counts the recognition result of the fed back NFC tag 10, and when the class is ended, the administrator terminal 300 determines whether or not the tag is present using the tagging frequency. For example, if the class time is 60 minutes and the automatic recognition period is 10 minutes, if the tag is tagged 5-6 times, if it is tagged 3 ~ 4 times, when it is tagged, if it is tagged less than 2 times, And the number of tagging times for determining presence / absence / absence / absence / departure can be set through the administrator terminal 300.

Next, the administrator terminal 300 transmits the determined attendance / perception / absence / exit status results to the web server, and the web server collects the received results into a database and collectively manages the student's bachelor's.

Meanwhile, the administrator terminal 300 may change the tagging period of the NFC tag 10 at random, or may set the additional tagging to be performed at an arbitrary point in a state in which the tagging is periodically performed. Also, the time corresponding to the attendance / absence / perception state can be set based on the tagging information (time information).

For reference, some methods for controlling the tag terminal 300 to proceed at an arbitrary point in time are as follows.

First, an arbitrary point in time can be specified, and the tagging point can be automatically specified irregularly using the random function provided by the application.

In addition, after receiving the attendance information of the previous class from the web server, the administrator terminal 300 can be automatically set to generate the tagging point in the time zone in which the abdomen occurred previously.

At this time, when the attendance information of the previous class is received from the web server, the manager terminal 300 receives the attendance information of all the classes of the school as well as the attendance information of the current class, And can be automatically set so that the tagging time is generated in a time zone in which the escapees occur more than a predetermined number of times. At this time, the time zone in which the escapees occur more than a predetermined number of times may be configured to be detected by the web server, and then only the corresponding information is transmitted to the administrator terminal 300.

Meanwhile, when the user (student) needs to use the student terminal 100 during the class, when the tagging time comes while the student terminal 100 is separated from the NFC tag 10,

The application of the student terminal 100 may operate to automatically perform the tagging operation again after a predetermined delay time if the tagging operation does not proceed after the tagging time arrives.

For example, if the delay time is set to 5 minutes, even if the tagging time arrives, the tagging operation is automatically performed again five minutes later, so that the state in which the user is instantly searching for information is prevented from being determined as the leaving state have. The number of times that the delay time and the delay time are allowed is set in the administrator terminal 300.

At this time, the application of the student terminal 100 may proceed with a detection operation to prevent the case where the delay time is abused. For example, assuming that the delay time is set to "5 minutes"

When the user (student) continuously uses more than 90% of "5 minutes" for a predetermined number of times, the tagging time and the delay time are automatically detected as being exposed and the delay time is automatically changed to 50% or less of the initial setting time , And the allowable frequency can be automatically changed to 50% or less.

For reference, a pressure sensor may be additionally disposed on a desk or a chair. The pressure sensor further senses whether or not a student is seated and then transmits detection information to the manager terminal 300 to determine the attendance status of the student So that it can be utilized as information.

The administrator terminal 300 can view the information of the sitting student by seat and can set the attendance manually in case the student does not carry the student terminal 100. [

The application of the student terminal 100 is configured to be able to confirm the attendance record of the student terminal 100 through the process of exchanging data with the administrator terminal 300 or the web server after the completion of the class, and to check the class schedule and the like.

The proposed Smart Attendance System can verify attendance situation more accurately, so it can grasp surrogate attendance and abandon status, so it can improve student 's satisfaction about grade calculation.

In addition, since the student terminal 100 must be placed on the desk, the concentration of the class can be improved.

The smart attendance system capable of discriminating the abductees according to the embodiment of the present invention can recognize the attendance state based on the number of tagging times by recognizing the NFC tag attached to the desk at every period set by the administrator, have.

Therefore, the administrator terminal can display the attendance status, absence status, and exit status of the student in real time and manage it.
