  According to the electronic name tag system of Patent Document 1, personal information can be displayed only within a specific area, so that illegal use of personal information and information leakage can be prevented. However, since the personal information is stored as display data in the storage part of the electronic name tag, if the electronic name tag is lost or obtained illegally, the display data is analyzed, and the personal information is illegally obtained for crime. May be used. In addition, we will reissue the electronic name tag for users who have lost the electronic name tag, but since the lost electronic name tag is genuine, it may be misused unless it is invalidated in some way. The time and effort required for this becomes complicated. Furthermore, if the attribute information other than the name such as the grade and the group number is changed for students or students, or the attribute information other than the name such as the department and job title is changed for the occupation, the display data of each electronic name tag is displayed. Needs to be rewritten, and it takes much time to rewrite the display data.

  When the electronic name tag system of Patent Document 1 enters or leaves a specific area, it is necessary to notify the electronic name tag management terminal of the user's entry / exit by operating a switch or through an authentication card, for example. is there. Therefore, there is no problem when a small number of users enter or leave a specific area, but when a large number of users try to enter or leave the area at the same time, a notification is sent to the electronic name tag management terminal. It takes a lot of time. For example, when the electronic name tag system disclosed in Patent Document 1 is introduced into a school or the like, the entrance of a school gate or school building is crowded when going to and from school, making it difficult for students and students to enter and exit smoothly.

An object of the present invention is to provide an electronic name tag excellent in information security that can reliably prevent personal information from being analyzed and misused even if the electronic name tag is lost or illegally acquired. To provide a system.
The object of the present invention is that the host terminal can easily change the attribute information other than the name and reissue the electronic name tag when it is lost, and is easier to handle and manage than the conventional electronic name tag system. Is to provide an electronic name tag system.
An object of the present invention is to display personal information on an electronic name tag by simply passing through a communication area of a reader / writer, or to stop the display, and even when a large number of users enter and exit at the same time, the user can enter and exit It is to provide an electronic name tag system that can smoothly perform the above.

  As shown in FIG. 1, an electronic name tag system according to the present invention includes an electronic name tag 1 that displays personal information of a user, a reader / writer 4 disposed at an entrance / exit gate 2, and a host terminal 5 that controls the reader / writer 4. It has. The electronic name tag 1 includes a display body 12 that displays personal information, a display control unit 13 that controls the display state of the display body 12, a communication unit 14 that performs wireless communication with the reader / writer 4, and a power source 15. The display control unit 13 of the electronic name tag 1 includes a display storage unit 21 that stores font data such as characters and symbols displayed on the display body 12, and the communication unit 14 includes a communication storage unit 23 that stores a name tag ID. ing. The host terminal 5 includes a data storage unit 34 that stores personal information data, and a data control unit 35 that transmits and receives data between the reader / writer 4 and the data storage unit 34. When a user enters from the entrance / exit gate 2, communication is established between the reader / writer 4 and the electronic name tag 1, and the personal information data acquired from the data storage unit 34 of the host terminal 5 based on the name tag ID is stored in the electronic name tag 1. And displayed on the display 12. When the user leaves the entrance / exit gate 2, communication is established between the reader / writer 4 and the electronic name tag 1, and display of personal information on the display body 12 is stopped.

  An entrance / exit detection unit 3 for specifying a user's passing direction is arranged at the entrance / exit gate 2. The entry / exit detection unit 3 specifies whether the user has entered or exited, and sends a display command from the reader / writer 4 to the electronic name tag 1 to display personal information data on the display body 12 or sends a display stop command. Then, the display of the display body 12 is stopped.

  When the user enters from the entrance / exit gate 2, the reader / writer 4 establishes communication with the electronic name tag 1, acquires the name tag ID from the communication storage unit 23 of the electronic name tag 1, and sends it to the data control unit 35 of the host terminal 5. To do. The data control unit 35 acquires personal information data from the data storage unit 34 based on the name tag ID received from the reader / writer 4 and sends it to the display control unit 13 of the electronic name tag 1 via the reader / writer 4. Upon receiving the personal information data, the display control unit 13 of the electronic name tag 1 acquires necessary font data from the display storage unit 21 and displays the personal information on the display body 12.

  The host terminal 5 is provided with a data management unit 36 for changing and adding personal information data recorded in the data storage unit 34. When re-issuing the electronic name tag 1, the data management unit 36 invalidates the name tag ID of the lost electronic name tag 1, and stores the re-issued name tag ID of the electronic name tag 1 in the data storage unit 34 together with the personal information data.

  The entrance / exit detection unit 3 includes a plurality of optical sensors 29A to 29C and 30A to 30C that are separated from the entrance / exit gate 2 along the direction of passage of the user. When the plurality of optical sensors 29A to 29C and 30A to 30C detect the passing of the user, the passing direction of the user at the entrance / exit gate 2 is specified by the difference in detection operation of each of the optical sensors 29A to 29C and 30A to 30C. .

  The entrance / exit detection unit 3 is arranged inside and outside the entrance / exit gate 2 with the reader / writer 4 in between, and an entrance side reader / writer 41 and an exit side for recording an entrance flag or an exit flag in the communication storage unit 23 of the electronic name tag 1. The reader / writer 42 is used. The entry / exit flag recorded in the communication storage unit 23 of the electronic name tag 1 is read by the reader / writer 4, and it is determined by the data control unit 35 provided in the host terminal 5 whether the user enters or exits.

  Individual passages 6 through which only one user can pass are provided at a plurality of places in the entrance / exit gate 2, and the entrance / exit detection unit 3 and the reader / writer 4 are arranged for each individual passage 6. Communication is established between the electronic name tag 1 worn by the user who passes through the individual passage 6 and the reader / writer 4, and the display of the electronic name tags 1 of a plurality of users who pass through the entrance / exit gate 2 is stopped.

  In the electronic name tag system of the present invention, personal information data is stored in the data storage unit 34 of the host terminal 5, and the name tag ID, font data, and the like are stored in the electronic name tag 1. In addition, when the user enters the entrance / exit gate 2, communication between the electronic name tag 1 and the reader / writer 4 is established, and the name tag ID stored in the electronic name tag 1 is used as a key from the data storage unit 34. The information data is transferred to the electronic name tag 1 and personal information is displayed on the display 12. When the user leaves the entrance / exit gate 2, communication is established between the reader / writer 4 and the electronic name tag 1 to stop displaying personal information on the display body 12.

  According to the above electronic name tag system, since the display of personal information on the electronic name tag 1 is stopped when the user leaves the entrance / exit gate 2, the personal information is unnecessarily exposed or illegally obtained. Can be prevented. Also, since no personal information remains on the electronic name tag 1 of the user who has left the entrance / exit gate 2, the personal information is lost even if the electronic name tag 1 is lost or illegally obtained. Can be reliably prevented from being analyzed and abused, and information security can be improved. Further, since the personal information data of the user is stored together in the data storage unit 34 of the host terminal 5, the host terminal 5 performs the change of attribute information other than the name and the reissue process when the electronic name tag 1 is lost. As compared with the conventional electronic name tag system, handling and management of the electronic name tag system can be facilitated.

  According to the electronic name tag system in which the entrance / exit detector 3 is arranged at the entrance / exit gate 2, the entrance / exit detector 3 can clearly identify whether the user has entered or exited. Therefore, even when a user who has entered from the entrance / exit gate 2 exits and enters again, the personal information data can be displayed on the display body 12 and the display can be stopped more reliably, so personal information is unnecessary. It is possible to more reliably prevent exposure to the public or illegal acquisition.

  When the data management unit 36 is provided in the host terminal 5 and the electronic name tag 1 is reissued, if the name tag ID of the lost electronic name tag 1 is invalidated by the data management unit 36, the lost electronic name tag 1 is used illegally. Information security of the electronic name tag 1 can be further improved. Therefore, it is possible to reliably prevent leakage of personal information due to misuse of the lost electronic name tag 1 and entry of a malicious person other than the related person into the specific area.

  If the user's passing direction in the entrance / exit gate 2 is specified by the difference in detection operation of the plurality of optical sensors 29A to 29C and 30A to 30C, the user's entrance and exit operations can be clearly specified. It is possible to accurately display and stop displaying personal information. Moreover, since the entrance / exit detection part 3 can be comprised using a commercially available optical sensor, the cost required for introduction of an electronic name tag system can be reduced.

  When the entrance / exit detection unit 3 is configured by the entrance-side reader / writer 41 and the exit-side reader / writer 42, an entrance flag and exit flag are stored in the electronic name tag 1 before the user passes through the entrance / exit gate 2. , The user's entry / exit can be identified more reliably. This is because, when wireless communication is performed between the reader / writer 4 and the electronic name tag 1, the entry / exit of the user can be instantly identified electronically by the entrance flag and the exit flag that have been converted into data. In addition, since the user's entry / exit is specified by wireless communication between the reader / writer 4 and the electronic name tag 1, the user can be kept in a stable state without being influenced by the weather or being disturbed by the light emitted from the headlight of the car. Entry / exit of can be identified.

  When individual passages 6 are provided at a plurality of locations in the entrance / exit gate 2 and the entrance / exit detector 3 and the reader / writer 4 are arranged for each individual passage 6, the user simply passes through the communication area of the reader / writer 4 and the electronic name tag 1 Personal information can be displayed on or stopped. Further, when the user passes through the entrance / exit gate 2, the user does not need to notify the host terminal 5 of the entrance / exit, so even if a large number of users enter or leave at the same time, the user can enter / exit the user. It is possible to go smoothly and avoid congestion and confusion at the entrance / exit gate 2.

The electronic paper 12 is fixed to the inner surface of a transparent display window 16 provided on the front surface of the case 9, and displays or stops displaying the student's personal information data. In this embodiment, the name of each student, attribute information other than the name such as grade, group, and seating, and the school name are displayed on the electronic paper 12 (see FIG. 3).

  As shown in FIG. 1, the display control unit 13 includes a display driver 19 that controls the display state of the electronic paper 12, a display controller 20 that controls the overall operation of the display control unit 13, and characters displayed on the electronic paper 12. And a display storage unit 21 for storing font data such as symbols. The display controller 20 is connected to the communication unit 14 and switches the electronic name tag 1 between a standby mode for receiving an activation signal sent from the communication controller 22 described later and a display mode for displaying personal information data on the electronic paper 12. be able to.

  Specifically, the display controller 20 acquires necessary font data from the display storage unit 21 based on the personal information data acquired from the host terminal 5 via the communication unit 14 at the time of attending school, operates the display driver 19, and operates electronic paper. 12 shows personal information data. When the display process in the display mode is completed, the display controller 20 is again switched to the standby mode while the personal information data is displayed on the electronic paper 12. Further, when leaving the school, the display driver 19 is operated based on the stop command acquired via the communication unit 14 to erase the display on the electronic paper 12 and stop the display.

  The communication unit 14 includes a communication controller 22, a communication storage unit 23, and a dipole antenna 24. When the electronic name tag 1 enters the communication area of the reader / writer 4, the communication controller 22 is activated by the electromotive force when the antenna 24 receives the transmission wave radiated from the reader / writer 4, and is transmitted from the reader / writer 4. The name tag ID stored in the communication storage unit 23 is transmitted to the reader / writer 4 based on the command signal. The communication storage unit 23 stores a name card ID and a program for controlling wireless communication with the reader / writer 4. The communication storage unit 23 also functions as a memory that temporarily stores personal information data transmitted from the reader / writer 4.

  The name tag ID is a unique identification code of the communication controller 22, and a different name tag ID is assigned to each electronic name tag 1. Wireless communication between the communication unit 14 and the reader / writer 4 uses UHF band (920 MHz) radio waves as a communication medium, and performs communication control based on a communication standard (EPC Global Class-1 Generation-2). It is not necessary for the name tag 1 to be close to or in close contact with the reader / writer 4.

  As shown in FIG. 2, the ascending / descending school detection unit 3 includes three sets of projectors (light sensors) 29A, 29B, and 29C arranged at regular intervals on the gate pillars 26 and 27 that sandwich the individual passage 6 therebetween, and the previous gate pillar 26. -It comprises three sets of light receivers (light sensors) 30A, 30B, 30C arranged at regular intervals on the gate pillars 27, 28 facing 27. When the student passes between the gate pillars 26, 27, and 28, the detection light emitted from the projectors 29A, 29B, and 29C toward the light receivers 30A, 30B, and 30C is blocked by the student. It is possible to know in which order the received light signals 30B and 30C were interrupted. For example, when the light reception signals of the light receivers 30A, 30B, and 30C are interrupted in the order of 30C, 30B, and 30A, it is possible to specify that the student has passed through the school gate 2 in the entrance direction. It is possible to specify that the vehicle has passed in the exit direction. In addition, when the light reception signal of the light receiver 30B provided at the intermediate position is interrupted, it is possible to specify whether to enter or leave. At this time, a display command is transmitted from the reader / writer 4 to the electronic name tag 1 to display personal information data. Or stop the display by sending a display stop command.

  The reader / writer 4 is embedded in the ground of the individual passage 6 and connected to the host terminal 5, and transmits a transmission wave to the electronic name tag 1 through the patch antenna 33 or a reflection transmitted from the electronic name tag 1. Receive waves. The host terminal 5 includes a personal computer and includes a data storage unit 34, a data control unit 35, and a data management unit 36. As shown in FIG. 4, the data storage unit 34 stores a name tag ID, personal information data such as name, grade, group, seat order, etc., and history data of going to and from school.

  The data control unit 35 receives the detection data from the ascending / descending school detection unit 3, and further acquires the personal information data acquired from the data storage unit 34 based on the name tag ID received via the reader / writer 4 via the reader / writer 4. 1 to send. The data management unit 36 is provided for managing personal information data in the data storage unit 34, creates a database of personal information data, adds or corrects the created database, and reissues an electronic name tag. Used in cases. Since the data stored in the data storage unit 34 can be collectively displayed on the display of the host terminal 5 by starting the data management unit 36, for example, data such as school year, group, seating order, etc. for each group, Or it can be changed collectively for each grade. Therefore, as compared with the case where personal information data is stored in each electronic name tag 1, it is possible to easily change attribute information other than the name.

  Next, an outline of data exchange between the electronic name tag 1 and the host terminal 5 at the time of attending school and leaving the school will be described. As shown in FIG. 2, a student who goes to school wears an electronic name tag 1 on the chest part of his clothes and enters the school through an individual passage 6 provided in the school gate 2. For example, at 8:00 am, the reader / writer 4 receives a command signal from the host terminal 5 and starts transmitting a transmission wave. When the student approaches the school gate 2 and the electronic name tag 1 in the standby mode enters the communication range of the reader / writer 4, the communication controller 22 of the electronic name tag 1 generates an electromotive force generated in the antenna 24 by the transmission wave radiated from the reader / writer 4. To establish communication between the electronic name tag 1 and the reader / writer 4. At this time, the reader / writer 4 acquires the name tag ID stored in the communication storage unit 23 via the reflected wave of the antenna 24 and sends it to the data control unit 35 of the host terminal 5. The data control unit 35 acquires personal information data from the data storage unit 34 using the name tag ID received from the reader / writer 4 as a key, and sends it to the display control unit 13 of the electronic name tag 1 via the reader / writer 4. The display control unit 13 that has received the personal information data acquires necessary font data from the display storage unit 21 and displays the personal information on the electronic paper 12 as shown in FIG. Since a series of processing can be performed while students pass through the school gate 2, even when a large number of students pass through the school gate 2 at the same time, it is possible to smoothly enter and exit the students without being crowded. it can.

  In parallel with the display of the personal information on the electronic paper 12, the host terminal 5 specifies that the student has passed through the school gate 2 in the entrance direction from the light reception signals of the light receivers 30A, 30B, and 30C, and the history data of going to and from school Rewrite to ○. If necessary, the time of attending school may be recorded as personal information data. When the display process in the display mode is completed, the display controller 20 is switched to the standby mode while the personal information data is displayed on the electronic paper 12, and the operation of the electronic name tag 1 is stopped. Thus, in the state where the operation of the electronic name tag 1 is stopped, the power of the power source 15 is not consumed, so that the replacement interval of the power source 15 can be increased. The host terminal 5 stops its operation when a certain period of time has elapsed since the start of work. However, if the student goes to school before the closing time due to personal circumstances or early withdrawal, the host terminal 5 is activated. To handle when going to school or leaving school.

  Since the student's school leaving time may vary depending on the grade, the host terminal 5 is activated in accordance with the school leaving time that is the earliest, and a transmission wave is transmitted from the reader / writer 4. When the student approaches the school gate 2 and the electronic name tag 1 in the standby mode enters the communication range of the reader / writer 4, the communication controller 22 of the electronic name tag 1 transmits the antenna by the transmission wave radiated from the reader / writer 4 in the same way as when going to school. 24 is activated by the electromotive force generated at 24, and communication is established between the electronic name tag 1 and the reader / writer 4. At this time, the reader / writer 4 confirms the name tag ID stored in the communication storage unit 23 via the reflected wave of the antenna 24, and then sends a command for stopping the display of the electronic paper 12 to the communication controller 22. Upon receiving the stop command, the communication controller 22 operates the display driver 19 to erase the display on the electronic paper 12 and stop the display. At the same time, based on the name tag ID received from the reader / writer 4, the data control unit 35 erases the history data of going to and from school and leaves it blank, and erases the font data stored in the display control unit 13.

  The electronic name tag 1 may be lost at the time of attending school or at home, and the lost electronic name tag 1 may be illegally acquired. However, the personal information data is only stored in the host terminal 5, and only the font data and the name tag ID remain in the electronic name tag 1. Therefore, even if the electronic name tag 1 is illegally acquired and analyzed, personal information is not leaked. The electronic name tag 1 is reissued to the student who has lost the electronic name tag 1. In this case, the host terminal 5 is activated, the name tag ID of the lost electronic name tag 1 is invalidated by the data management unit 36, and the name tag ID of the electronic name tag 1 reissued is stored in the data storage unit 34 together with the personal information data. By doing so, it is possible to reliably prevent the lost electronic name tag 1 from being misused. Issuance and invalidation of the electronic name tag 1 when a student moves in or out can be easily performed on the host terminal 5 side, so that an electronic name tag system that is easier to handle and manage than the conventional electronic name tag system can be provided.

  5 and 6 show another embodiment of the electronic name tag system. In this case, as shown in FIG. 6, the three reader / writers 4 are arranged between the gate pillars 26 and 27 of the school gate 2, and the entrance-side reader / writer 41 arranged inside and outside of the school gate 2 with the reader / writers 4 in between. The exit side reader / writer 42 constitutes the entrance / exit detection unit 3. Like the reader / writer 4, the entrance-side reader / writer 41 establishes communication with the electronic name tag 1, erases the exit flag recorded in the communication storage unit 23, and stores the entrance flag. The exit side reader / writer 42 establishes communication with the electronic name tag 1 in the same manner as the reader / writer 4, erases the entrance flag recorded in the communication storage unit 23, and stores the exit flag. The reader / writer 4 determines whether the student has entered or exited by the data control unit 35 provided in the host terminal 5 depending on whether the entry flag or the exit flag is stored in the communication storage unit 23. Update school attendance history data. In FIG. 5, reference numeral 43 denotes an antenna.

  The student at the time of going through the entrance side reader / writer 41 and the reader / writer 4 and then passes through the exit side reader / writer 42, but when entering the school, the entrance flag is set by stopping the operation of the exit side reader / writer 42. It can be prevented from being erased. Similarly, it is possible to prevent the exit flag from being erased by stopping the operation of the entrance-side reader / writer 41 when leaving school. Since others are the same as the previous embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted.

  As described above, according to the entrance / exit detection unit 3 configured by the entrance-side reader / writer 41 and the exit-side reader / writer 42, an entrance flag or exit flag is placed on the electronic name tag 1 before the student passes through the school gate 2. Is stored, so that it is possible to more reliably identify the student's going to and from school. Incidentally, when the light sensor is used as a detection element, the light receivers 30A to 30C may malfunction due to the influence of the weather or the irradiation light of the headlight of the automobile, and moreover, it is easy to be tampered with using the pocket light. However, this malfunction can be eliminated. In addition, even when a plurality of students pass through the school gate 2 side by side, communication is established between each student's electronic name tag 1 and each reader / writer 41 and 42 to ensure that the students enter and leave. Can be identified.

  The electronic name tag system of the present invention can be applied to name tag management at entry / exit in a specific area such as a company, a public institution, a research institute, or an airport, in addition to name tag management at the time of going to and from school. In addition, by distributing the electronic name tag 1 to visitors at the exhibition hall, and by setting up a reader / writer at each exhibition booth at the exhibition hall, know the busyness of the exhibition booth and the behavior of the visitors at the exhibition hall. Data can be collected for.

  In the above embodiment, the entrance / exit of the student is detected by the three sets of transmission type optical sensors, but the optical sensor may be a reflection type optical sensor. Further, it is sufficient that at least two sets of optical sensors are arranged inside and outside the school gate 2. Furthermore, school attendance time and school leaving time are set in the host terminal 5, personal information is displayed on the electronic name tag 1 of the student who has passed the school gate 2 during the school attendance time period, and the school gate 2 is passed during the school attendance time period. The personal information displayed on the student's electronic name tag 1 may be deleted. In that case, the host terminal 5 also serves as the entrance / exit detection unit 3. The power supply 15 may be a secondary battery. Even if the personal information display is stopped by printing the school emblem or school name or the company house mark or company name on the surface of the electronic paper 12, the school emblem or school name or mark is displayed.
