If the student establishes communication between the electronic name tag 1 and the reader / writers 41 and 42, but the student notices a forgotten thing and turns back without passing through the school gate, the entrance flag is not stored. It is good to do so. By the way, it is also possible to configure the ascending / descending school detection part (entrance / exit detection part) 3 by using the light sensor as a detection element for going to and from school (entrance / exit). The receiver may malfunction due to the irradiating light, and moreover, it is susceptible to mischief using a pocket light, but such 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. In FIG. 1, reference numeral 43 denotes an antenna. In addition to this, a direct current voltage (for example, DC 24 V) is applied to the school gate 2 from the outside, and a power supply circuit that converts the direct current voltage into an alternating supply voltage and an alternating supply voltage of the power supply circuit are contactlessly connected. The primary coil (not shown) for supplying power is provided, and the primary coil and the secondary coil 111 of the power receiving means 11 are magnetically coupled to each other. A transmission / reception unit for transmitting / receiving a display command signal or a display stop command signal S ₁ to / from the arithmetic processing means 14 is provided.

  The reader / writer 4 is connected to the host terminal 5 and transmits a transmission wave to the electronic name tag 1 via the patch antennas 43 and 44 or receives a reflected wave transmitted from the electronic name tag 1. Further, the reader / writer 4 uses a data control unit 35 provided in the host terminal 5 to determine whether a student has entered or exited depending on whether an entry flag or an exit flag is stored in the communication storage unit 33. Judgment and update school attendance history data.

  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. 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, and the like can be displayed for each group. Or you can change it for each grade at once. 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. 1, a student who goes to school wears an electronic name tag 1 on a chest part of clothes and enters the school from 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 as a predetermined area, the communication controller 32 of the electronic name tag 1 receives the antenna 31 by the transmission wave radiated from the reader / writer 4. The communication is established 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 33 via the reflected wave of the antenna 31 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 driving means 13 of the electronic name tag 1 via the reader / writer 4. The driving 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 if a large number of students pass through the school gate 2 at the same time, the students can go to school (go to school) smoothly without being crowded. .

  In parallel with the display of the personal information on the electronic paper 12, the host terminal 5 identifies that the student has passed through the school gate 2 in the entrance direction from the going-and-coming school detection unit 3, and sets the history data of the going-and-going school to “attending school”. rewrite. 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. As described above, in the state where the operation of the electronic name tag 1 is stopped, when the power source (battery) is provided, the power is not consumed, so that the replacement interval of the power source (battery) 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 enters or leaves the school after the start of work or before the end of work due to the circumstances of the student or early withdrawal, the host terminal 5 is started and processing at the time of attending school and leaving school is performed.

  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 32 of the electronic name tag 1 uses the transmission wave radiated from the reader / writer 4 to transmit the antenna. It is activated by the electromotive force generated at 31 and establishes communication 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 33 via the reflected wave of the antenna 31, and then sends a command for stopping the display of the electronic paper 12 to the communication controller 32. Upon receiving the stop command, the communication controller 32 operates the driving means (display driver) 13 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 deletes the history data of going to and from school and leaves it blank, and deletes the font data stored in the driving means 13.

Next, the operation (display or display stop) of the electronic name tag on the display body to which the mobile power supply management apparatus according to the present embodiment is applied will be described based on the above configuration.
First, as described above, a case where a user (student) wears an electronic name tag and goes to / from a school where he / she attends school will be described with reference to each of the drawings. When the student passes through the school gate 2, communication is established between the electronic name tag 1 and the reader / writer 4. The reader / writer 4 acquires the name tag ID and transmits it to the host terminal 5. A display command signal S ₁ is output to the arithmetic processing means 14 of the electronic name tag 1.

In the electronic name tag 1, the primary coil of the power transmission means 23 and the secondary coil 111 of the power reception means 11 are magnetically coupled within the school gate 2, and power is supplied from the power transmission means 23 via the power reception means 11, and the display command signal S ₁ Based on the above, the arithmetic processing means 14 executes the arithmetic operation related to the driving operation in the school gate 2. The arithmetic processing means 14, the receiving means 11 via a magnetic coupling with the secondary coil 111 and primary coil and outputs a power transmission means 23 to the power receiving control signal S ₃ of the school gate 2, the driving of the electronic nameplate 1 (driving means 13) Request the desired power required for operation.

Transmission means 23 on the basis of the power reception control signal S ₃ is the power from the power supply circuit supplied DC voltage (DC24V) from the outside is excited by energizing the primary coil, the secondary magnetic field generated by the exciting by interlinked to the coil 111, and supplies the electric power based on the power reception control signal S ₃ by electromagnetic induction to the electronic name tag 1.

  Next, an operation that enables display on the electronic name tag 1 that is fed by the power transmission means 23 of the school gate 2 will be described with reference to the respective drawings. In each of the drawings, the operation that enables display on the display body 12 of the electronic name tag 1 that has passed through the school gate 2 is performed by the power supply control of the power received by the power receiving means 11 and the arithmetic processing of the arithmetic processing means 14. The

Power received in the receiving means 11, by the rectifier circuit 112 is rectified to a DC voltage of 6.7 V, at the timing T ₁ and adjust the regulator 113 to the DC voltage to a preset constant DC voltage 6.5V Output (step 1-1). The receiving voltage of the adjusted constant DC voltage 6.5V is charged as the charging voltage 6.0V in the capacitor _{C 16} at the timing of _{T 1} through the diode _{D 16} of the feed assist means 16 (step 1-2).

When the charging capacitor C ₁₆ of the feed auxiliary means 16 raises the potential to 6V by charging is completed, adjusted at step 2-1 the arithmetic processing means 14 and the current supply means 15 connected in parallel to the capacitor C ₁₆ Each received voltage is applied (step 1-3). Among these, the power supply adjusting means 15 generates a drive voltage of 5.0 V that requires the LDO 151 and outputs it to the MOS-FETs 152, 153, and 154 (step 1-4).

Further, the arithmetic processing unit 14 generates an MCU power supply voltage of 3.3 V that requires the LDO 141 from the received voltage (6.0 V) applied with a voltage drop by the diode D ₁₆ and outputs it to the MCU 142 (step). 1-5). This MCU 142 controls and calculates the operation of the driving means 13 necessary for the user to display or stop the display on the display body 12 in the electronic name tag 1 by the MCU power supply voltage of 3.3V. MCU142 in the control calculation operation outputs a power receiving control signals _{S 3} with respect to the power receiving unit 11 at the timing _{T 2} (step 1-6), and outputs a driving control signal _{S 2} with respect to current supply means 15 ( Step 1-7).
