<CPU 100>
FIG. 4 is a block diagram showing an example of a functional configuration in the CPU 100 of FIG. The CPU 100 includes a current position calculation unit 111, an in-area entry determination unit 112, a home position and tag ID storage unit 113, a notification request generation unit 114, a charge start detection unit 115, an end request generation unit 116, and a remaining battery level detection unit 117. The charging necessity determination unit 118 and the charging notification unit 119 are configured.

  The current position calculating unit 111 obtains the current position of the terminal itself based on the positioning signal received by the GPS receiving unit 102. The current position is obtained by discriminating the distance between the GPS satellite and the terminal from the reception result of the positioning signal. Usually, a three-dimensional position on the earth can be accurately determined by receiving positioning signals from four or more GPS satellites almost simultaneously.

  The in-area entry determination unit 112 determines whether or not the user carrying the portable information terminal 10 has entered the in-home area 2, that is, whether or not the user has returned home, and the determination result is notified to the notification request generation unit 114. Output to. Whether the user has returned home is determined by comparing the current position obtained by the current position calculation unit 111 with a pre-registered home position or by pre-registering ID information received by the tag ID receiving unit 103 It is discriminated by collating with.

  The home position and tag ID storage unit 113 holds position information indicating the position of the home and the ID code of the RF tag 24. Of the above two methods for determining whether or not the user has returned home, the user can arbitrarily specify which method to select.

  The notification request generation unit 114 generates a charge notification request based on the determination result of the in-area entry determination unit 112. The charge notification request is transmitted to the home notification device, that is, the TV receiver 21 and the PC 22 by the home communication unit 104.

  Charging start detection unit 115 detects the start of charging of the secondary battery and outputs the detection result to end request generation unit 116. For example, the voltage Vj at the charging terminal is compared with the determination threshold value VT1, and if the voltage Vj is equal to or higher than the determination threshold value VT1, it is determined that charging of the secondary battery has started. After transmitting the charging notification request, the termination request generation unit 116 generates a notification termination request based on the detection result of charging start. The notification end request is transmitted by the home communication unit 104 to the home notification device from which a response to the charge notification request is obtained.

  The remaining battery level detection unit 117 detects the remaining battery level of the secondary battery, and outputs the detection result to the charging necessity determination unit 118. For example, the remaining battery level can be determined by the voltage Vh at the discharge terminal.

  After transmitting the charging notification request, the charging necessity determination unit 118 performs charging of the secondary battery based on the detection result of the illuminance S by the illuminance sensor 18 and the detection result of the remaining battery level by the remaining battery level detection unit 117. The necessity is determined, and the determination result is output to the charging notification unit 119. Specifically, the illuminance S is compared with the determination threshold ST, and if the predetermined time T or more passes with the illuminance S decreasing below the determination threshold ST, it is determined that the user is in a state before going to bed.

  If the user is in the state before going to bed, the voltage Vh of the discharge terminal is compared with the determination threshold value VT2, and if the voltage Vh becomes equal to or lower than the determination threshold value VT2, it is determined that the secondary battery needs to be charged. That is, when the state where the illuminance S is equal to or less than the determination threshold value ST continues for a certain time T or more and the voltage Vh is equal to or less than the determination threshold value VT2, it is determined that the secondary battery needs to be charged.

  On the other hand, when the illuminance S exceeds the determination threshold value ST or the voltage Vh exceeds the determination threshold value VT2, it is determined that the secondary battery is not required to be charged. The charging notification unit 119 generates notification control data for prompting the user to charge the secondary battery based on the determination result of whether or not charging is necessary, and the display control unit 105, the sound processing unit 107, and the vibrator 108 are generated. Output to.

  For example, a charging message indicating that the secondary battery needs to be charged is displayed on the touch panel 11 based on the notification control data. Alternatively, a predetermined melody or warning sound is output from the speaker 17. Alternatively, charging notification is performed using the LED indicator 16 and the vibrator 108. That is, the charging notification is performed by displaying a charging message, lighting the LED indicator 16, voice, or vibration. The user can arbitrarily specify which notification method is selected.

  Steps S201 to S214 in FIG. 5 are flowcharts showing an example of the operation of the portable information terminal 10. This flowchart shows a case where it is determined whether or not the user has returned home based on a positioning signal received from a GPS satellite.

  First, the current position calculation unit 111 calculates the current position based on the positioning signal received from the GPS satellite (step S201). The in-area entry determination unit 112 determines whether or not the user has returned home based on the measured current position, that is, whether or not the user has entered the house (step S202).

  When it is detected that the user has entered the house, the notification request generation unit 114 turns on the power to the home communication unit 104 to start up, and generates a charge notification request. This charge notification request is transmitted to the home notification device by the home communication unit 104 (steps S203 and S204). Then, the charging message is transmitted to the in-home notification device from which the permission response is obtained (steps S205 and S206).

  Next, the charging necessity determining unit 118 turns on the power to the illuminance sensor 18 to start up, and determines whether or not the illuminance S has decreased below a certain level (steps S207 and S208). When the illuminance S decreases below a certain level, the charging necessity determining unit 118 checks the remaining battery level detected by the remaining battery level detecting unit 117 and determines whether it is below the certain level (step S209). , S210).

  If the charging necessity determining unit 118 determines that the remaining battery level is equal to or lower than a certain level and the secondary battery needs to be charged, the charging notification unit 119 starts charging notification (step S211). Next, if the charging start detection unit 115 detects that charging of the secondary battery is started, the charging notification unit 119 ends the charging notification (steps S212 and S213). Then, the end request generation unit 116 generates a notification end request and transmits the notification end request to the home notification device by the home communication unit 104 (step S214).

<In-house notification device>
FIG. 6 is a block diagram showing a configuration example of the home notification device, and shows a TV receiver 21 as an example of the home notification device. The TV receiver 21 includes a TV receiver 211, a broadcast program display unit 212, an LCD 213, an audio output unit 214, a speaker 215, a home communication unit 216, and a notification control unit 217.

  In addition, the TV receiver 21 includes a program viewing mode and a standby mode as switchable operation modes when the main power is on. The program viewing mode is an operation mode in which a TV broadcast signal is received and a program video is displayed. On the other hand, the standby mode is a standby mode in which power supply to the TV receiving unit 211, the broadcast program display unit 212, the LCD 213, and the audio output unit 214 is cut off. If the main power source is in an on state, communication with the portable information terminal 10 is possible in any operation mode of the program viewing mode or the standby mode. In contrast, the charging notification is performed in the program viewing mode.

  The TV receiving unit 211 is a broadcast signal receiving unit that receives a TV broadcast signal from a broadcast station. The broadcast program display unit 212 is a program video display unit that displays a program video on the screen based on the received TV broadcast signal. The program video is displayed on an LCD (liquid crystal display device) 213. The audio output unit 214 outputs program audio from the speaker 215 based on the received TV broadcast signal.

  The home communication unit 216 connects to the home network 20 and performs wireless communication with the portable information terminal 10 via the wireless AP 23. The notification control unit 217 performs charging notification for prompting charging of the portable information terminal 10 based on the charging notification request and the notification end request received from the portable information terminal 10.

  For example, during the display of the program video, a charging notification such as displaying on the LCD 213 a charging message indicating that the mobile information terminal 10 needs to be charged is performed. Since the charging message is displayed on the screen while the program video is displayed, the user can be surely recognized that the mobile information terminal 10 needs to be charged after the user enters the in-home area 2. Such charging notification is started based on the charging notification request received from the portable information terminal 10, and is automatically ended based on the notification end request.

  Steps S301 to S309 in FIG. 7 are flowcharts illustrating an example of the operation of the home notification device. This flowchart shows the operation of the TV receiver 21 from the reception of the charging notification request to the end of the display of the program video.

  First, when the in-house communication unit 216 receives a charging notification request, the notification control unit 217 determines whether a program video is being displayed or is in a standby state (steps S301 and S302). At this time, the notification control unit 217 stores the charging message received from the portable information terminal 10 in the memory in the standby state, that is, the standby state in which the power supply to the TV receiving unit 211 and the LCD 213 is cut off, and broadcast program It waits until the standby state is canceled based on a user operation for starting viewing (steps S308 and S309).

  The notification control unit 217 displays a charging message if the program video is being displayed when the charging notification request is received or if the standby state is canceled and the program video is displayed on the LCD 213 (step S303).

  When the home communication unit 216 receives a notification end request, the notification control unit 217 ends the message display (steps S304 and S305). The broadcast program display unit 212 ends the display of the program video when a user operation for ending viewing is detected (steps S306 and S307).

  According to the present embodiment, since the charging notification request is transmitted to the in-home notification device based on the determination result of whether or not the user carrying the portable information terminal 10 has entered the in-home area 2, the user can Immediately after entering 2, the in-house notification device can be instructed to charge. For this reason, if the main power source of the portable information terminal 10 is switched to the off state after the user enters the in-home area 2, even if the main power source of the portable information terminal 10 is off, The user can be notified that charging is necessary.

  Such charging notification can prevent the portable information terminal 10 from being left unusable and unusable the next day. In addition, if the in-home area 2 is composed of a plurality of rooms and a home notification device is installed in each room, charging notification is performed using these home notification devices. Therefore, the user is informed that charging of the portable information terminal 10 is necessary regardless of whether the user has the portable information terminal 10 or whether the user is in the same room as the portable information terminal. be able to.

  In addition, since the charging notification by the in-home notification device is performed based on the charging notification request and the notification end request that the portable information terminal 10 transmits based on the detection result of the charging start, charging of the portable information terminal 10 is started. Nevertheless, the in-home notification device can be prevented from continuing the charging notification.

  Further, in the charging notification system 1 according to the present embodiment, since it is determined whether or not the user has entered the home area 2 based on the current position obtained from the positioning signal, the fact that the user has entered the home area 2 is determined. It can detect automatically and can perform charge alerting | reporting.
