Description

[0001] CLUSTERING OF LOCATION-BASED SMART DEVICES ATTENDANCE RECORDING SYSTEM [0002]

[0001] The present invention relates to a student attendance record system, and more particularly, to a position attendance record system in which a position value of a lecturer is clustered based on a GPS (Global Positioning System) Location clustering based smart device attendance recording system.

Generally, the lecturer checks the attendance of each student at every lecture time, assigns the attendance score based on him / her every semester, and reflects the attendance score to give a final grade to each student.

The electronic attendance system is a system for confirming attendance by using ICT technology, escaping from the existing method of checking attendance through the caller name. Especially, it is a system to construct the class time so that it can utilize the class time more effectively in large scale lectures. In addition, since the attendance department that has been recorded / managed offline can be turned into an online system, teachers, students, and parents can check the attendance status anytime and anywhere.

Especially, in the case of large-scale lectures, it takes a considerable time to check attendance because there are many attendants, and it is a considerable time to score a large number of students in assigning scores to the school rules based on the number of absences And labor.

The electronic check-out system was started to resolve the inconvenience of attendance check according to the call. Conventionally, the electronic check-out system automatically checks whether or not the attendees attend the lecture by using attendance check means (mobile communication terminal, IC card, etc.) separately possessed by the attendants. At this time, the attendance check means is integrated into the identification card (or the student card, the registration card), and the attendance person contacts the check terminal with the identification card to confirm the attendance.

However, there is a difficulty in that the attendance person must purchase the attendance check means separately. If the attendee does not own his attendance check means and attends the lecture, it is not recognized as attendance.

Especially, checking the attendance electronically causes a problem of identity verification. Even when the attendance check means of the attendee is held by another person and attended the lecture, problems such as being recognized as attendance occur. In other words, it is difficult to confirm whether the person checking the attendance is the person or the agent of the party, and thus the problem of surrogate attendance arises. For example, if you ask your friend to give you an RFID card, you do not know it, so you are authenticated by your attendance.

Also, there is a problem that it is not possible to check the attendance even if you do not participate in the class. Therefore, the actual usage rate is very low even though the university has invested a huge amount of money to build an electronic attendance system.

It is not difficult to actually implement the attendance system. However, it is important to know how to prevent attendance by attending attendance certification. However, in the case of the prior art [Patent Literatures 1 and 2], there is only a difference in the authentication method for the lecturers, and technologies for checking and checking proxy attendance are not presented.

As a conventional technique for solving the above problems, there is Korean Registration No. 10-1425345 (hereinafter, referred to as "prior art") of a smart device-based electronic pager system using a Wi-Fi beacon frame.

The present invention relates to an authentication method of an electronic pavilion system for connecting a lecture mobile terminal and a lecture mobile terminal to a server via a wireless network and connecting the lecture attendant and the lecture mobile terminal to a wireless access device via a local area wireless communication network, on

(A) transmitting, to the server, the authentication allowance time of the entrance and the unique information extracted from the wireless access device (hereinafter referred to as first unique information) to the server; (b) (C) the lecturer mobile terminal transmits identification information of a student and a mobile terminal, and unique information extracted from the radio access device (hereinafter referred to as " second information " (D) the server checks whether the first and second unique information match with each other, and authenticates the attendance of the student according to whether the first and second unique information are matched with each other Wherein the first and second unique information are extracted from a beacon frame transmitted from the wireless access device, and the beacon frame is broadcast by the wireless access device It characterized.

In the prior art, a Wi-Fi beacon frame is used to construct an electronic pendant system. However, it must be equipped with a wireless connection device capable of transmitting indoor or Wi-Fi beacon frames, There is a problem in that it can not be used.

FIG. 4 is a flowchart showing in detail the process of attending and recording at the device 30 and the server 10. FIG.

In order to construct a smart device attendance recording system based on the position clustering of the present invention, a lecture attendant and a learner terminal device (hereinafter referred to as " lecture attendant ") composed of a terminal device having a built-in GPS (Global Positioning System A server 10 for managing the attendance data such as the unique identification information of the lecturer and the lecturer, the attendance course, the lecture date, the authentication allowance time, and the like, from the server 10, And a database 40 for receiving and recording the attendance data such as the attendance courses and the attendance dates.

 Here, the unique identification information is preferably composed of the mobile phone number of the terminal device of the lecturer and the learner, and the identification number of the terminal device.

Also, in order to identify a learner requesting authentication, the portable telephone number, the terminal device identification number, and the GPS value of the terminal device are extracted and compared with the information of the learner, and it is proved that the learner is close to the lecturer position, can do.

The database 40 manages lecture-related information including lecture name, lecture time, lecturer, lecturer attendance information, lecture attendance information, and the like for each lecture, and acquires personal information of each lecture attendee, terminal identification information, lecture attendance information, Related information including the information is stored.

The lecturer terminal device 20 and the learner terminal device 30 are connected to the server 10 through a wireless network and the lecture terminal device 20 and the learner terminal device 30 measure GPS values using the GPS system Anything that can be done is possible.

The server 10 includes an attendance record information input step S10 for inputting attendance information such as unique identification information of a lecturer and a lecturer, attendance subjects, lecture dates, etc., in order to construct a attendance record database 40, 20 is a step of transmitting location information of the lecturer terminal device 20 to the server 10 via the wireless network, and the server 10 transmits the location information of the lecture terminal device 20 to the lecturer terminal 20, Clustering the GPS values of the terminal devices transmitted through the device 20 to set an authentication range and transmitting an admission authentication data transmission step S30 including an authentication permission time and an attendance subject to the learner terminal 30, 30 verifies the attendance authentication data transmitted from the server 10, the identification information of the principal, the attendance course, the lecture date, and transmits the GPS value of the learner terminal 30 to the server 10 via the network Lecturer The server 10 transmits the device 30 location transmission step S40 and the server 10 confirms whether the GPS value of the verified participant terminal device 30 is included in the authentication range of the clustered terminal device 20 (Step S50).

 At this time, the GPS values of the lecturer and the learner are "

Err1 is the error of the lecture GPS value, Bm is the learner's GPS value, Br is the learner's actual position, err2 is the error of the learner's GPS value). Is set,

 In this case, when the two values of err1 and err2 are close to each other, err1 and err2 are approximated by the error values of the lecturer and the learner, so that the difference between Am and Bm is significantly reduced.

 This is because, if they are located in the same area, it is judged that the difference between Am and Bm is insignificant because the errors of the GPS values recognized by the respective terminal devices are the same or similar.

Therefore, if err1 and err2 are close to each other, err can be canceled, and the position of Br located within the clustered authentication range can be more accurately determined from the position of Ar.

Therefore, when the GPS position values of lecturers and learners are measured indoors, the positional clustering is used to offset the error effect of GPS values when they are on the same line. It is possible to measure the position.

Further, in the position transmission step of the lecturer's terminal device 20, the lecturer terminal device 20 sets the authentication permitted time, the attendance subject, and the unique identification information of the lecturer, and transmits the GPS value extracted from the terminal device using the GPS system to the server 10).

In addition, the lecture-based terminal device (20) is further characterized in that it is possible to set an attestation authentication range around the lecturer.

 Herein, the completion of the attendance recording includes forming a plurality of groups by clustering the GPS values extracted from the learner terminal 30, and the plurality of groups include unique identification information, Absence, absence, lag, and midway departure by determining whether or not the clustering lecturer is close to the GPS value within the allowed time.

 If the lecturer enters the authentication range of the clustered lecturer within the authentication allowance time, the attendance is made. If the lecturer enters the authentication range within the authentication end time, , And when it is time to finish the class, the absence process is performed.

 At this time, if the person who leaves the group clustered before the designated class end time is assigned to the attendance of the attendance within the allowance time for the attendance authentication, it is judged that the student is suddenly departed.

That is, if the attendance is out of the attendance authentication range before the end of the class time, it is determined that the student is suddenly out of the class, and it is possible to prevent the attendance member from escaping the attendance authentication range during the class time.

Next, a method by which the lecturer terminal unit 20, the learner terminal unit 30, and the server 10 authenticate the attendance for attendance authentication according to an embodiment of the present invention will be described with reference to FIG. The lecturer, the learner terminal 30 and the server 10 will be described.

 As shown in FIG. 5, the server 10 according to the present invention receives and stores data on attendance subjects, passwords, lecture dates, authentication time, lecturers, and attendance information.

First, the lecturer terminal device 20 extracts a GPS value and unique identification information, and transmits the attendance subject, the lecture GPS value, the authentication permission time, and the unique identification information of the terminal device to the server 10. At this time, the authentication permission time, unique identification information, and the like are used as data for authentication for the attendance subject.

 Next, only the lecturer unit receives the attendance subject information, the attendance date, the attendance person GPS value, the unique identification information of the terminal device, and the like, which are information of the attendance person, and uses it as attendance authentication data.

That is, the server 10 checks whether the attendance subjects of the received attendees and the unique identification information of the terminal apparatus are identical to the entered attendee information, and is excluded from attendance authentication if it does not coincide with the previously entered attendee information.

Here, if the attendance subjects, the attendance date, and the unique identification information of the terminal device match, the server 10 clusters based on the lecturer GPS value to set the attendance authentication range.

 Next, the GPS value is compared only with the learner who matches the learner information inputted to the server 10, and if it is included in the location authentication cluster that is clustered in the center of the lecturer, the process proceeds to the next step (A) The process proceeds to step (C).

It is judged whether or not the student who entered the step (A) has been input within the authentication permission time inputted to the server 10, and the student entered within the authentication permission time goes to the next step (B) The student who has entered the course will proceed to step (C).

Next, if the learner goes to the step (B), the process goes to the step (E) if the learner is included in the location-clustered attendance authentication range until the end of the lecture time input to the server 10, If the user leaves the coverage range before the time point, the process proceeds to step (D).

 Here, among the students attending to the step (C), if they are included in the location clustered approval authentication range before the end of the class time, they are treated as perceptions, and the students who are not included in the approval authentication range until the end .

 Attendance information is entered into the database 40 through the steps (C), (D), and (E).
