<System configuration>
First, the outline of the attendance management system according to one embodiment will be described.

  FIG. 1 is a diagram showing a configuration example of an attendance management system according to an embodiment. The attendance management system 100, for example, uses information terminals of attendees who attend lectures and classes to provide information (hereinafter referred to as attendance information) indicating whether or not the attendees attended lectures and classes. It is a management system. Note that the lectures and classes attended by attendees may be, for example, classes at universities, high schools, elementary and junior high schools, prep schools, cram schools, or at lectures, trainings, events, etc. sponsored by organizations such as companies and local governments. It may be.

  1, the attendance management system 100 includes a location information management server 101, an attendance management server 102, a content server 103, a gateway 104, an output device 105, an information terminal 107 possessed by attendees 106, a management terminal 108, and the like. The number of the gateway 104, the output device 105, the information terminal 107, and the management terminal 108 in FIG. 1 is an example, and the number may be one or more other numbers.

  The position information management server (position information management device) 101 is, for example, an information processing device connected to a network 109 such as the Internet or a LAN (Local Area Network), or a system including a plurality of information processing devices. The location information management server 101 can communicate with the attendance management server 102, the gateway 104, the information terminal 107, etc. via the network 109. Further, the position information management server 101 can communicate with the output device 105 via the wireless network provided by the gateway 104.

  The position information management server 101 controls the output of sound waves from the output device 105 installed in the attendance place 110 (for example, a classroom) where a lecture or the like attended by the attendee 106 is held. For example, the position information management server 101 controls the output device 105 to output and stop sound waves, and sets and changes predetermined identification information (hereinafter referred to as output ID) included in the sound waves.

  Further, when the position information management server 101 receives the request information including the output ID included in the sound wave output by the output device 105, the location information management server 101 informs the request source of the request information (for example, the information terminal 107, attendance management server 102, etc.) to the attendance place. It provides 110 information (eg, classroom name, classroom ID, etc.).

  The attendance management server (attendance management device) 102 is connected to the network 109 and is capable of communicating with the position information management server 101, the content server 103, the information terminal 107, the management terminal 108, etc., or a plurality of information processing devices. It is a system including.

  The attendance management server 102 manages attendance information indicating whether or not the attendee 106 attended a lecture or the like held at the attendance place 110, based on the presence information received from the information terminal 107 of the attendee 106. The presence information transmitted by the information terminal 107 to the attendance management server 102 includes, for example, information for identifying the information terminal 107, information on the attendance place 110 acquired by the information terminal 107 from the location information management server 101, and the like. Be done.

  Further, as another example, the presence information transmitted from the information terminal 107 to the attendance management server 102 includes an output ID acquired from the output device 105 by the information terminal 107, instead of the information of the attendance place 110. Is also good. In this case, the attendance management server 102 can transmit the request information including the output ID received from the information terminal 107 to the location information management server 101 and acquire the attendance location information from the location information management server 101.

  It is a system including an information processing device or a plurality of information processing devices connected to the content server 103 and the network 109 and capable of communicating with the attendance management server 102, the information terminal 107, the management terminal 108 and the like.

  The content server 103, for example, registers in advance the content (for example, a document file etc.) used in the lecture held at the attendance place 110, and provides the content to the information terminal 107 of the attendant 106. For example, the lecturer who gives a lecture at the attendance place 110 uses the management terminal 108 to previously register the document file or the like used in the lecture in the content server 103. In addition, the attendant 106 uses the information terminal 107 to access the content server 103 to browse or acquire a document file or the like.

  Preferably, the output device 105 is installed such that the arrival range 111 of the sound wave output by the output device 105 is within the attendance place 110 and the sound wave reaches the entire attendance place 110. For example, when the attendance place 110 is large, a plurality of output devices 105 are installed at the attendance place.

  In addition, it is desirable that the sound wave output by the output device 105 is an inaudible sound that cannot be (or hardly heard) by a general person. Thereby, the output device 105 can output the sound wave including the output ID while suppressing the influence on the lecture held at the attendance place 110.

  Preferably, the sound wave output by the output device 105 is a sound wave of 16 kHz or higher. Since a sound wave having a high frequency has high straightness and is difficult to pass through a wall or the like, the reach range 111 of the sound wave of the output device 105 can be suppressed within the range of the attendance place 110.

  Note that the output device 105 is described below as a speaker device that outputs sound waves by itself, but the output device 105 outputs sound waves to an existing speaker or the like installed at the attendance place 110, for example. It may be an audio signal output device or the like.

  The information terminal 107 is an information processing device used by the attendees 106, such as a smartphone, a tablet terminal, or a PC (Personal Computer).

Further, the information terminal 107 transmits, for example, request information including the output ID acquired at the attendance location 110 to the location information management server 101, and acquires the information about the attendance location 110 from the location information management server 101. Further, the information terminal 107 stores the presence information including the identification information for identifying the information terminal 107 (hereinafter, referred to as application ID) and the information on the attendance place 110 acquired from the position information management server 101, in the attendance management server 102. Send to.

  The attendance management server 102 manages attendance information of attendees of the information terminal 107 using the presence information and the time information received from one or more information terminals 107 in the attendance place 110. As the time information used for managing the attendance information, for example, information on the time when the information terminal 107 acquires the output ID is included in the attendance information and transmitted. Alternatively, the time information used for managing the attendance information may be the time when the attendance management server 102 receives the presence information from the information terminal 107, or the output device 105 transmits the output ID. It is also possible to use information of the time zone to be used. In short, the time information used for managing the attendance information may be any information that allows the information terminal 107 to specify the time or the time zone at which the sound wave including the output ID is acquired at the attendance place 110.

  The management terminal 108 is an information processing device such as a PC used by an administrator (for example, a lecturer) to register a lecture schedule in the attendance management server 102 or register content (for example, a document file) in the content server 103. is there.

  As a suitable example, the location information management server 101 is a cloud service operated by a service provider or the like that provides location information management services. An administrator (for example, a school) that manages the attendance management server 102 installs the location information management server 101 by managing the attendance of the attendee 106 using the information of the attendance place 110 provided by the cloud service. Costs, management costs, etc. can be saved.

Note that the schedule information acquired by the application from the attendance management server 102 includes, for example, the schedule of the lecture of the day and information on the time zone in which the sound wave including the sound wave ID is output from the output device 105 of the attendance place 110 in each lecture. Etc. are included.

  In FIG. 2, when "Lecture 1" is started at time 9:00, the output device 105 installed at the attendance place 110 is based on the output information set before the start of the lecture, and the sound wave ID "ID001". The transmission (output) of the sound wave including is started. Further, the information terminal 107 automatically activates the application based on the schedule information acquired before the start of the lecture, and the activated application executes the process of confirming the presence of the attendant 106. In the presence confirmation process, for example, the information terminal 107 acquires the attendance place information from the position information management server 101 using the sound wave ID acquired from the output device 105, and acquires the attendance place information and the application ID. The attendance information including “A” is transmitted to the attendance management server 102.

  At time 9:10, the output device 105 stops the transmission of the sound wave including the sound wave ID “ID001” based on the output information set before the lecture starts. It should be noted that the transmission time of 10 minutes of the sound wave including the sound wave ID “ID001” is merely an example.

  At time 9:30, the output device 105 starts transmitting a sound wave including the sound wave ID “ID002” based on the output information set before the start of the lecture. Further, the information terminal 107 automatically activates the application based on the schedule information acquired before the start of the lecture, and the activated application executes the process of confirming the presence of the attendant 106.

  At time 9:40, the output device 105 stops transmission of the sound wave including the sound wave ID “ID002” based on the output information set before the start of the lecture.

  The RTC 709 has a clock function and outputs time information such as the current time and date in response to a request from the CPU 701 or the like. Further, the RTC 709 can generate an alarm interrupt or the like at a set time.

<Functional configuration>
Next, the functional configuration of the attendance management system 100 will be described.

  FIG. 8 is a functional configuration diagram of the attendance management system according to the embodiment. The attendance management system 100 includes a location information management server 101, an attendance management server 102, a content server 103, a gateway 104, an information terminal 107, and the like that can communicate via the network 109. The attendance management system 100 also includes an output device 105 capable of communicating with the position information management server 101 via the gateway 104. The management terminal 108 shown in FIG. 1 is, for example, a general-purpose PC that can use a web browser, and therefore its description is omitted here.

(Functional configuration of location information management server)
The position information management server 101 has an information management unit 801, an information receiving unit 802, an output control unit 803, an information providing unit 804, a communication control unit 805, and a storage unit 806.

  The information management unit 801 stores and manages information on the location where one or more output devices 105 are installed in the output device information 807 of the storage unit 806. The information management unit 801 is realized by, for example, a program that operates on the CPU 401 in FIG.

  An example of the output device information 807 managed by the information management unit 801 is shown in FIG. In the example of FIG. 9A, the output device information 807 corresponds to a plurality of output device IDs that are identification information of the output devices 105 and location information that is information of the location where each output device 105 is installed. It is also remembered. In the output device information 807 illustrated in FIG. 9A, for example, the output device 105 having the output device ID “SP0001” is installed in the first classroom.

  Note that the output device information 807 in FIG. 9A is just an example. For example, the location information of the output device information 807 is a location ID that is identification information of the location where the output device 105 is installed, position information (coordinate information, etc.) of the location where the output device 105 is installed, and the like. Is also good.

  The information receiving unit 802 sends information from the attendance management server 102 to the communication control unit 805, including information about the attendance place 110 that is the target of attendance management and information about the time zone in which the output device 105 outputs sound waves at the attendance place 110. To receive through. The information management unit 801 is realized by, for example, a program that operates on the CPU 401 in FIG.

  The output control unit 803 causes the output device 105 installed in the attendance place 110 in the corresponding time zone based on the time zone information and the attendance place 110 information received by the information receiving unit 802 from the attendance management server 102. , The sound wave including the designated output ID is output. The output control unit 803 is realized by, for example, a program that operates in the CPU 401 in FIG.

  For example, the output control unit 803 stores the output control information 808 shown in FIG. 9B in the storage unit 806 and manages it. In the example of FIG. 9B, the output control information 808 includes items of “location information”, “output device ID”, “time zone”, “date and time”, and “output ID”.

  The “place information” is information on the attendance place 110 received from the attendance management server 102 by the information receiving unit 802.

  The “output device ID” is the output device ID of the output device 105 installed in the attendance place 110 corresponding to the “place information”, and the output control unit 803 acquires it from the output device information 807 shown in FIG. 9, for example. And remember.

  The “time zone” and the “date and time” are information on the time zone received from the attendance management server 102 by the information receiving unit 802.

  The “output device ID” is an output ID that the output control unit 803 causes the output device 105 to output. In the example of FIG. 9B, the output device 105 with the output device ID “SP0001” installed in the first classroom has the date and time “20xx.01.20 09: 00-090: 10” (first time period). It is shown that a sound wave including the output ID “ID001” is output.

  The output control unit 803, for example, outputs to the output device 105 corresponding to the “output device ID” information about one or more time zones (for example, “time zone” and “date and time”) and “output” for each time zone. The output control information including the “device ID” is transmitted to the output device 105 and stored therein. The output device 105 stores in advance the output control information transmitted from the output control unit 803 to the own device, and executes the output process of the sound wave including the designated output ID at the stored time zone.

  In addition, as another example, the output control unit 803 causes the output devices 105 to “display” when the output device 105 outputs a sound wave based on the output control information 808 illustrated in FIG. 9B. The start instruction and the stop instruction of the sound wave output including the “output ID” may be transmitted.

  Further, the output control unit 803 may use the above two output control methods together.

  Preferably, the output control unit 803 changes the output ID to be output by the output device 105 according to the time zone. When there are a plurality of attendance places 110 (for example, classrooms), the output control unit 803 outputs different output IDs for each attendance place.

  The method of changing the output ID may be arbitrary, but for example, output IDs different from each other and larger than the number of attending places may be prepared in advance. Alternatively, the output ID may be generated based on, for example, the output device ID using a code (for example, an encryption key, a scramble code, etc.) that differs depending on the time zone.

  When the communication control unit 805 receives the request information including the output ID included in the sound wave output by the output device 105 installed at the attendance place 110, the information providing unit 804 requests the request information from the attendance place 110. Provide information. The information providing unit 804 is realized by, for example, a program that operates on the CPU 401 in FIG.

  For example, when the information providing unit 804 receives request information requesting acquisition of location information of the attendance location 110 corresponding to the above output ID from the information terminal 107, the information providing unit 804 notifies the information terminal 107 based on the output control information 808. Information on the attendance place 110 (for example, the first classroom) is transmitted. Similarly, when the information providing unit 804 receives the above request information from the attendance management server 102, the information providing unit 804 transmits the information on the attendance place 110 to the attendance management server 102.

  The communication control unit 805 is means for communicating with the attendance management server 102, the gateway 104, the information terminal 107, and the like using the network I / F unit 405 of FIG. 4, and is realized by a program that operates on the CPU 401 of FIG. To be done.

  The storage unit 806 is a unit that stores the output device information 807, the output control information 808, and the like, and is realized by, for example, the storage unit 404 of FIG. 4, the RAM 402, and a program that operates in the CPU 401 of FIG.

It is realized by the program.

  The lecture information management unit 812 stores and manages the lecture information 820, which is information about the lecture held at the attendance place 110, in the storage unit 819. The lecture information management unit 812 is realized by, for example, a program that operates on the CPU 401 in FIG.

  FIG. 10A shows an example of the lecture information 820. In the example of FIG. 10A, the lecture information 820 includes “lecture”, “lecture ID”, “place”, “time”, “instructor”, “student”, “student ID”, “app ID”. ", Etc. are included.

  “Lecture” is the name of the lecture for which attendance management server 102 manages attendance. The “lecture ID” is identification information for identifying a lecture. “Place” is information on the place where the lecture is given (attendance place 110). The "time" is information on the time zone in which the lecture is held. “Lecturer” is information on the lecturer (for example, the name of the lecturer, the lecturer ID, etc.).

  “Attendee” is information (for example, the names of the attendees) of the attendees who are allowed to attend the lecture. The “student ID” is identification information for identifying a student (for example, student ID, employee ID, attendance ID, etc.). The “application ID” is identification information that identifies the student's information terminal 107.

  The application ID is identification information of the application generated by the application when the application corresponding to the attendance management system 100 is installed in the information terminal 107, for example. The application operating on the information terminal 107 can generate a unique application ID for each information terminal 107 based on, for example, identification information of the information terminal 107, for example, unique information such as IMEI (International Mobile Equipment Identity). .. By using such an application ID, the attendance management system 100 can identify the information terminal 107 of the attendee 106 without depending on the personal information of the attendee 106.

  The application ID is an example of terminal identification information that identifies the information terminal 107. For example, the terminal identification information may be information such as identification information (device ID) unique to the information terminal 107, a telephone number, and a MAC address.

  When the information (necessary for creating the lecture information 820) is input by the administrator (for example, a lecturer) using the web browser of the management terminal 108, the lecture information management unit 812 is as shown in FIG. The lecture information 820 is generated and stored in the storage unit 819.

  The schedule information management unit 813 is schedule information that is information on one or more time zones in which the output device 105 outputs the sound wave including the output ID at the attendance place 110 based on the lecture information 820 stored in the storage unit 819. 821 is created and stored in the storage unit 819. The schedule information management unit 813 is realized by, for example, a program that operates on the CPU 401 in FIG.

  FIG. 10B shows an example of the schedule information 821. In the example of FIG. 10B, the schedule information 821 includes items such as “place”, “time zone”, and “date and time”.

  “Place” is information on the attendance place 110 where the lecture is held.

  The “time zone” and the “date and time” are information on the time zone in which the sound wave including the output ID is output at the attendance place 110.

  Preferably, the schedule information 821 includes a plurality of time zones. The number of times and the lengths of the plurality of time zones may be designated by the administrator using the management terminal 108, or may be automatically generated by the schedule information management unit 813.

  For example, the schedule information management unit 813 sets the first period (for example, 10 minutes) from the start time of the lecture as the first time period and the third period before the lecture (for example, 10 minutes) as the third time period. Alternatively, the second time period may be set for the second period (for example, 10 minutes) during the lecture. Alternatively, the schedule information management unit 813 may set more time zones.

  The schedule information notification unit 814 notifies the schedule information 821 created by the schedule information management unit 813 to the position information management server 101 and the information terminal 107 via the communication control unit 811. The schedule information notification unit 814 is realized by, for example, a program that operates on the CPU 401 in FIG.

  For example, when the schedule information 821 is updated, the schedule information notification unit 814 notifies the position information management server 101 of the updated schedule information 821.

  In addition, the schedule information notification unit 814 notifies the information terminal 107 of schedule information regarding a lecture attended by the attendee 106 in response to a request for acquisition of schedule information from the information terminal 107 of the attendee 106. For example, in FIG. 10, when the schedule information notification unit 814 receives the acquisition request for the schedule information from the information terminal 107 with the application ID “1010001”, the schedule of the first classroom in which the lecture 1 that the student A attends is held. The information is notified to the requesting information terminal 107.

  The attendance information management unit 815 manages attendance information of attendees based on the presence information transmitted from the information terminal 107 of the attendee 106 via the communication control unit 811. The attendance information management unit 815 is realized by, for example, a program that operates on the CPU 401 in FIG.

  The presence information transmitted from the information terminal 107 of the attendee 106 includes, for example, the application ID of the information terminal 107 and information for specifying the attendance place 110 where the information terminal 107 is located.

  The information for specifying the attendance place 110 is, for example, the information of the attendance place 110 acquired from the output device 105 by the information terminal 107. Alternatively, the information that specifies the attendance place 110 may be the output ID obtained from the output device 105 by the information terminal 107 at the attendance place 110.

  FIG. 11A shows an example of attendance information 822. In the example of FIG. 11A, the attendance information 822 includes “lecture”, “lecture ID”, “time”, “student”, “student ID”, “app ID”, “first time zone”. ”To“ third time zone ”and“ attendance determination ”and the like are included.

  The information of the "first time zone" to the "third time zone" is information indicating whether or not the attendance of the attendant 106 was confirmed by the information terminal 107 of the attendant 106 in each time zone. .. In the example of FIG. 11A, “attended” indicates that the attendance of the attendant 106 could be confirmed, and “absent” indicates that the attendance of the attendee could not be confirmed. There is.

  For example, the attendance information management unit 815 uses the application ID “1010001” and the location information “first classroom” of the attendance place 110 where the lecture 1 is held from the information terminal 107 of the attendee 106 during the first time period. It is assumed that the presence information including and is received. At this time, the attendance information management unit 815 verifies whether the received application ID “1010001” and the location information “first classroom” lecture information 820 of the attendance place 110 are included in the lecture information 820, for example. .. If the received application ID and the location information of the attendance place 110 are included in the lecture information 820, the attendance information management unit 815 regards the “first time zone” of the application ID “1010001” as “attended”. To do.

  The information of “attendance determination” is determined by the attendance information management unit 815 based on the information of “first time zone” to “third time zone” and indicates whether the attendee 106 participated in the lecture. It is information to show. The attendance determination shown in FIG. 11A is an example, and the attendance information management unit 815 may use any attendance determination method based on the information of “first time zone” to “third time zone”.

  For example, when all of the attendance information management unit 815 and the “first time zone” to the “third time zone” are “attended”, the attendance information management section 815 may determine the attendance. Alternatively, the attendance information management unit 815 may determine the attendance when the user is “attended” more than once in the “first time zone” to the “third time zone”.

  FIG. 11B shows another example of attendance information 822. In the example of FIG. 11B, the attendance information 822 includes “lecture ID”, “time”, “person present in first time zone” to “person present in third time zone”, and “ Items such as "Lecture attendees" are included.

  Of these, the “lecture ID” and “time” correspond to the “lecture ID” and “time” information included in the lecture information 820 of FIG.

  The application ID of the information terminal 107 whose presence can be confirmed in each time zone is stored in the information of “the person present in the first time zone” to “the person present in the third time zone”.

  The attendance information management unit 815 determined the attendance determination information based on the information of "the person present in the first time zone" to "the person present in the third time zone", and participated in the lecture. It is the student ID of the attendant 106.

  For example, as described above, the attendance information management unit 815 uses the information about attendance of the attendee 106 (for example, in FIG. 11) based on the plurality of presence information received from the information terminal 107 of the attendee 106 in a plurality of time zones. "Attendance judgment", "Lecture attendees", etc.) are managed.

[First Embodiment]
(Lecture information registration process)
FIG. 12 is a sequence diagram of an example of a lecture information registration process according to the first embodiment.

  In step S1201, the lecturer who registers the lecture information inputs the lecture information (for example, information on the lecture name, place, lecturer, time, etc.) on the lecture information registration screen of the management terminal 108. For example, the lecturer uses the web browser of the management terminal 108 to access the web server provided by the lecture information management unit 812 of the attendance management server 102, and inputs the lecture information on the displayed lecture information registration screen. ..

  In step S1202, the management terminal 108 requests the attendance management server 102 to register the lecture information input in step S1201. For example, the web server of the management terminal 108 transmits the lecture information input in step S1201 to the attendance management server 102.

  In step S1203, the lecture information management unit 812 of the attendance management server 102 creates, for example, the lecture information 820 shown in FIG. 10A based on the lecture information received from the management terminal 108 in step S1202. It is stored in the storage unit 819.
