The figure which shows the structure of the power supply control system concerning 3rd embodiment of this invention.

  First, the outline of the configuration of the power supply control system 100 will be described with reference to FIG.

  The power control system 100 automatically turns on / off the power of the terminal depending on whether the user carrying the terminal is in or out of the area (predetermined area) determined by the monitor. The control is performed. In the power supply control system 100, the user is a side to be monitored for entering and leaving a predetermined area, and is, for example, a child. The monitor is a side that monitors the user entering and exiting a predetermined area, and is, for example, a parent.

  The power supply control system 100 includes a user terminal 1, a supervisor terminal 2, and a server 3.

  The user terminal 1 is a terminal carried and used by the user. As the user terminal 1, a terminal capable of transmitting and receiving data (information) is used, for example, a personal computer or a high-performance mobile phone terminal. The user terminal 1 includes a power supply unit 1A, a function unit 1B, and a power supply switching unit 1C.

  The power supply unit 1 </ b> A supplies power to each unit of the user terminal 1. The power supply unit 1A is, for example, a storage battery, and stores power from an external power supply.

  The function unit 1B performs a main function of the user terminal 1. The function section 1B is a section other than the control section 10 described later, and has, for example, a call function and a mail function. The function unit 1B is connected to the power supply unit 1A via a power supply switching unit 1C described later.

  The power supply switching unit 1C is formed to be able to cut off the supply of power from the power supply unit 1A to the function unit 1B. The power supply switching unit 1C is arranged between the power supply unit 1A and the functional unit 1B. The power supply switching unit 1C is, for example, a switch, and is formed to be capable of ON / OFF operation. When the power supply switching unit 1C is turned ON, power is supplied from the power supply unit 1A to the function unit 1B. When the power supply switching unit 1C is turned off, the supply of power from the power supply unit 1A to the functional unit 1B is cut off. That is, the power supply switching unit 1C can switch between a state in which power is supplied from the power supply unit 1A to the function unit 1B and a state in which power supply from the power supply unit 1A to the function unit 1B is cut off.

  The user terminal 1 includes a control unit 10 that controls the user terminal 1. The control unit 10 includes a position information acquisition unit 11, a power supply control unit 12, and a transmission / reception unit 13.

  The position information acquisition unit 11 acquires position information of the user terminal 1. The location information acquisition unit 11 has a location information acquisition function such as a GPS (Global Positioning System) function, and thereby periodically acquires the current location information of the user terminal 1. As a result, the location information acquisition unit 11 can acquire the current location information of the user carrying the user terminal 1.

  The power supply control unit 12 controls the operation (ON operation / OFF operation) of the power supply switching unit 1C. The power supply control unit 12 switches the power supply state from the power supply unit 1A to the function unit 1B by controlling the operation of the power supply switching unit 1C. As described above, since the power supply control unit 12 controls the operation of the power supply switching unit 1C, as a result, it is determined whether the power is supplied from the power supply unit 1A to the functional unit 1B or the power supply is cut off. You can judge.

  When controlling the operation of the power supply switching unit 1C (switching of the power supply state), the power supply control unit 12 outputs the power supply information (power supply cutoff information and power supply cutoff release information) indicating the power supply state. Generate.

  The transmission / reception unit 13 transmits and receives data to and from the server 3 described below.

  The monitor terminal 2 is a terminal used by the monitor. As the monitor terminal 2, a terminal capable of transmitting and receiving data is used, and for example, a personal computer or a high-performance mobile phone terminal is used. The monitor terminal 2 includes a display unit 2A and an input unit 2B. The display unit 2A is a part that displays information to be transmitted to a monitor and a screen stored in advance. As the display unit 2A, for example, a liquid crystal display is used. The input unit 2B is a part where the monitor operates. As the input unit 2B, for example, a keyboard or a touch panel is used. Data is input to the monitor terminal 2 by the monitor operating the input unit 2B.

  The monitor terminal 2 includes a control unit 20 that controls the monitor terminal 2. The control unit 20 includes an area information setting unit 21, a display control unit 22, and a transmission / reception unit 23.

  The area information setting unit 21 sets area information relating to a predetermined area. The predetermined area is, for example, an area where the user is prohibited from entering inside while the power is supplied to the functional unit 1B of the user terminal 1. The predetermined area is, for example, a school. Area information regarding a predetermined area is set by operating the input unit 2B of the monitor terminal 2.

  The display control unit 22 performs control for displaying information to be transmitted to a monitor and displaying a screen stored in advance on the display unit 2A. The display control unit 22 can perform control to display the power supply information generated by the power supply control unit 12 on the display unit 2A, for example.

  The transmission / reception unit 23 transmits and receives data to and from the server 3 described below.

  The server 3 is configured to be able to transmit and receive data to and from the user terminal 1 and the supervisor terminal 2. The server 3 includes a control unit 30 that controls the server 3. The control unit 30 includes a position information storage unit 31, an area information storage unit 32, an area entry / exit determination unit 33, and a transmission / reception unit 34.

  The position information storage unit 31 stores the history of the position information of the user terminal 1 acquired by the position information acquisition unit 11 of the user terminal 1. Here, the history of the position information refers to the position information from the past to the present of the user terminal 1 acquired by the position information acquisition unit 11. The position information storage unit 31 stores a history of the position information of the user terminal 1 for a certain period including the present.

  The area information storage unit 32 stores the area information set in the area information setting unit 21 of the monitor terminal 2.

  The area entry / exit determination unit 33 determines whether the user terminal 1 is in a predetermined area or whether the user terminal 1 is out of the predetermined area. This determination is made based on the area information set in the area information setting unit 21 and the position information acquired by the position information acquisition unit 11. Specifically, the area entry / exit determination unit 33 compares the area information set in the area information setting unit 21 with the current position information of the user terminal 1 acquired by the position information acquisition unit 11, and When the current position of the user terminal 1 and the predetermined area overlap, it is determined that the user terminal 1 is within the predetermined area. On the other hand, when the current position of the user terminal 1 does not overlap the predetermined area, the area entry / exit determination unit 33 determines that the user terminal 1 is out of the predetermined area.

  The area entry / exit determination unit 33 generates area entry / exit information (area entry information and area exit information) indicating a user entry / exit situation in a predetermined area.

  The transmission / reception unit 34 transmits and receives data to and from the user terminal 1 and the supervisor terminal 2.

  Hereinafter, the flow of control by the power supply control system 100 will be described with reference to FIGS. 1 and 2.

  The supervisor (parent) activates the power control system 100 using the supervisor terminal 2 (step S10).

  When the power supply control system 100 is started, the setting screen of the area information stored in the monitor terminal 2 in advance is displayed on the display unit 2A of the monitor terminal 2 under the control of the display control unit 22. The observer operates the input unit 2B to input a desired area.

  The input of the area is performed using an address, a building name, geographic information, and the like. When an address, a building name, geographic information, and the like are input, an area range is specified next. The monitor inputs a desired radius such as “radius 10 m” or “radius 100 m” on the setting screen. As a result, a circle having the input radius centered on the input address or a certain point of the building is determined, and a range inside the circle is determined as an area. In the area information setting section 21, area information relating to this area is set (step S20). The area information set in the area information setting unit 21 is transmitted to the transmission / reception unit 34 of the server 3 via the transmission / reception unit 23. The area information received by the transmission / reception unit 34 is stored in the area information storage unit 32 (Step S30).

  Thus, in the power supply control system 100, the area information can be set by the observer. Since the user cannot change the area information set by the monitor, it is possible to prevent the area information from being changed by the user.

  The position information acquisition unit 11 of the user terminal 1 periodically acquires the position information of the user terminal 1. The acquired position information is transmitted to the transmitting / receiving unit 34 of the server 3 via the transmitting / receiving unit 13 (Step S40). The position information received by the transmission / reception unit 34 is stored in the position information storage unit 31 (Step S50).

  The area entry / exit determination unit 33 stores the area information stored in the area information storage unit 32 (set in the area information setting unit 21) and the area information stored in the position information storage unit 31 (acquired by the position information acquisition unit 11). ) Based on the current position information of the user terminal 1, it is determined whether the user terminal 1 has entered (entered) a predetermined area (step S60). The area entry / exit determination unit 33 compares the area information set in the area information setting unit 21 with the current position information of the user terminal 1 acquired by the position information acquisition unit 11, and determines the current position of the user terminal 1. Is determined to overlap with the predetermined area, it is determined that the user terminal 1 has entered the predetermined area ("YES" in step S60).

  On the other hand, when the current position of the user terminal 1 does not overlap with the predetermined area, the user terminal 1 has not yet entered the predetermined area (the user terminal 1 has exited outside the predetermined area). ) (“NO” in step S60).

  When determining that the user terminal 1 has entered the predetermined area ("YES" in step S60), the area entry / exit determination unit 33 generates area entry information indicating that the user has entered the predetermined area. . The area entry information generated by the area entry / exit determination unit 33 is transmitted to the transmission / reception unit 13 of the user terminal 1 via the transmission / reception unit 34.

  The power supply control unit 12 of the user terminal 1 controls the power supply switching unit 1C based on the area entry information received by the transmission / reception unit 13. Specifically, upon receiving the area entry information, the power supply control unit 12 turns off the power supply switching unit 1C. When the power supply switching unit 1C is turned off, the supply of power from the power supply unit 1A to the functional unit 1B is cut off (step S70). As a result, the user cannot use the main functions of the user terminal 1 (the functions of the function unit 1B such as the call function and the mail function).

  On the other hand, when the area entry / exit determination unit 33 determines that the user terminal 1 has not yet entered the predetermined area (the user terminal 1 has exited outside the predetermined area) (“NO” in step S60). ), And returns to step S40 again. The position information newly acquired by the position information acquisition unit 11 is transmitted to the transmission / reception unit 34 of the server 3 via the transmission / reception unit 13 (Step S40). Based on the area information stored in the area information storage unit 32 and the newly acquired current location information of the user terminal 1, the area entry / exit determination unit 33 re-enters the user terminal 1 in a predetermined area. It is determined whether or not it has entered (step S50, step S60).

  When turning off the power supply switching unit 1C, the power supply control unit 12 generates power supply cutoff information indicating that power supply from the power supply unit 1A to the functional unit 1B has been cut off. The power supply cutoff information generated by the power supply control unit 12 is transmitted to the transmission / reception unit 23 of the monitor terminal 2 via the transmission / reception unit 13 and the transmission / reception unit 34. The power supply cutoff information received by the transmission / reception unit 23 is displayed on the display unit 2A of the monitor terminal 2 under the control of the display control unit 22 (step S80). For example, “power has been turned off” is displayed on the display unit 2A.

  Thereby, the monitor can know that the user has entered the predetermined area and that the supply of power from the power supply unit 1A to the functional unit 1B has been interrupted.

  The power supply cutoff information generated by the power supply control unit 12 is also transmitted to the area entry / exit determination unit 33 of the server 3 via the transmission / reception unit 13 and the transmission / reception unit 34 (step S90). Thus, the area entry / exit determination unit 33 can grasp the current power supply state.

  The position information acquisition unit 11 newly acquires position information. The newly acquired position information is transmitted to the transmission / reception unit 34 of the server 3 via the transmission / reception unit 13 (Step S100). The position information received by the transmission / reception unit 34 is stored in the position information storage unit 31 (Step S110).

  The area entry / exit determination unit 33 stores the area information stored in the area information storage unit 32 (set in the area information setting unit 21) and the area information stored in the position information storage unit 31 (acquired by the position information acquisition unit 11). ) Based on the current position information of the user terminal 1, it is determined whether the user has gone out of the predetermined area (has left) (step S120). The area entry / exit determination unit 33 compares the area information set in the area information setting unit 21 with the current position information of the user terminal 1 acquired by the position information acquisition unit 11, and determines the current position of the user terminal 1. When the position does not overlap the predetermined area, it is determined that the user terminal 1 has moved out of the predetermined area ("YES" in step S120). On the other hand, when the current position of the user terminal 1 and the predetermined area overlap, it is determined that the user terminal 1 remains in the predetermined area ("NO" in step S120).

  When determining that the user terminal 1 has left the predetermined area (“YES” in step S120), the area entry / exit determination unit 33 generates area exit information indicating that the user has left the predetermined area. . The area exit information generated by the area entry / exit determination unit 33 is transmitted to the transmission / reception unit 13 of the user terminal 1 via the transmission / reception unit 34.

  The power supply control unit 12 controls the power supply switching unit 1C based on the area exit information received by the transmission / reception unit 13. Specifically, upon receiving the area exit information, the power supply control unit 12 turns on the power supply switching unit 1C. When the power supply switching unit 1C is turned on, the interruption of power supply from the power supply unit 1A to the function unit 1B is released, and power is supplied from the power supply unit 1A to the function unit 1B (step S130). As a result, the user can use the main functions of the user terminal 1 (the functions of the functional unit 1B such as the call function and the mail function).

  On the other hand, when the area entry / exit determination unit 33 determines that the user terminal 1 is still in the predetermined area (“NO” in step S120), the process returns to step S100. The position information newly acquired by the position information acquisition unit 11 is transmitted to the transmission / reception unit 34 of the server 3 via the transmission / reception unit 13 (Step S100). The area entry / exit determination unit 33 determines whether the user has left the predetermined area again based on the area information stored in the area information storage unit 32 and the newly acquired current position information of the user terminal 1. It is determined whether it is (Step S110, Step S120).

  When the power supply switching unit 1C is turned on by the control, the power supply control unit 12 generates power supply cutoff release information indicating that the cutoff of power supply from the power supply unit 1A to the functional unit 1B has been released. The power supply cutoff release information generated by the power supply control unit 12 is transmitted to the transmission / reception unit 23 of the monitor terminal 2 via the transmission / reception unit 13 and the transmission / reception unit 34. The power supply cutoff release information received by the transmission / reception unit 23 is displayed on the display unit 2A of the monitor terminal 2 under the control of the display control unit 22 (step S140). For example, “power has been turned on” is displayed on the display unit 2A.

  Thereby, the observer can know that the user has gone out of the predetermined area and that the cutoff of the power supply from the power supply unit 1A to the functional unit 1B has been released. Therefore, the observer can grasp the timing at which the user terminal 1 can make a call, mail, or the like.

  When the monitoring person is notified that the user has gone out of the predetermined area, the monitoring person ends the power supply control system 100 using the monitoring terminal 2 (step S150).

  As described above, in the power supply control system 100, the power supply state from the power supply unit 1A to the functional unit 1B is automatically controlled, so that the user needs to turn on / off the power supply of the user terminal 1 by himself / herself. Absent. Further, it is possible to prevent the power from being turned on in the area (school) when the user enters the predetermined area (arrival at the school). Further, when the user goes out of the predetermined area (goes out of school), it can be prevented that communication is not possible when necessary outside the area (outside the school).

  Further, the control unit 10 (the position information acquisition unit 11 and the power supply control unit 12) that controls the power supply state from the power supply unit 1A to the function unit 1B is directly connected to the power supply unit 1A without passing through the power supply switching unit 1C. Because of the connection, even when power is not supplied to the functional unit 1B, power is always supplied from the power supply unit 1A. Therefore, the power supply state from the power supply unit 1A to the functional unit 1B can be constantly controlled.

As described above, the power supply control system 100 according to the present embodiment is the power supply control system 100 of the user terminal 1 that is carried and used by the user, and the user terminal 1 is provided with the power supply unit 1A that supplies power.

  When the area entry / exit determination unit 33 detects that the user terminal 1 is in a predetermined area (“YES” in step S61), the location information newly acquired by the location information acquisition unit 11 (within the area) The position information after a lapse of a predetermined time (for example, 5 seconds) after the presence of the user terminal 1 is detected is transmitted to the transmission / reception unit 34 of the server 3 via the transmission / reception unit 13 (step S62). . The new position information received by the transmission / reception unit 34 is stored in the position information storage unit 31 (Step S63).

  The area entry / exit determination unit 33 checks the set area information and the predetermined information of the user terminal 1 stored in the location information storage unit 31 to check whether the user terminal 1 is continuously in the area. By comparing the position information after the lapse of time, it is detected again whether the user terminal 1 is within the predetermined area (step S64). When detecting that the user terminal 1 is in the predetermined area, the area entry / exit determination unit 33 determines that the user terminal 1 is in the predetermined area ("YES" in step S64).

  On the other hand, if the area entry / exit determination unit 33 detects that the user terminal 1 is outside the predetermined area in this detection ("NO" in step S64), the determination of the area entry / exit status is suspended, and the step is performed again. It returns to S40.

  If the area entry / exit determination unit 33 determines that the user terminal 1 has entered a predetermined area ("YES" in step S64), the power supply switching unit 1C is turned off by the same control as in the first embodiment. Then, the supply of power from the power supply unit 1A to the functional unit 1B is shut off (step S70). As a result, the user cannot use the main functions of the user terminal 1 (the functions of the function unit 1B such as the call function and the mail function).

  Steps S80 to S110 are the same as in the first embodiment.

  The area entry / exit determination unit 33 compares the area information set in the area information setting unit 21 with the current position information of the user terminal 1 acquired by the position information acquisition unit 11, and uses the area information outside the predetermined area. It is detected whether or not there is a user terminal 1 (step S121). When the current position of the user terminal 1 does not overlap with the predetermined area, the area entry / exit determination unit 33 detects that the user terminal 1 is outside the predetermined area (“YES” in step S121).

  On the other hand, when the current position of the user terminal 1 and the predetermined area do not overlap, it is detected that the user terminal 1 is not outside the predetermined area (the user terminal 1 is within the area) ( ("NO" in the step S121), and the process returns to the step S100 again.

  When the area entry / exit determination unit 33 detects that the user terminal 1 is outside the predetermined area (“YES” in step S121), the location information newly acquired by the location information acquisition unit 11 (use outside the area) After a lapse of a predetermined time (for example, 5 seconds) after the presence of the user terminal 1 is detected, the position information is transmitted to the transmission / reception unit 34 of the server 3 via the transmission / reception unit 13 (step S122). The new position information received by the transmission / reception unit 34 is stored in the position information storage unit 31 (Step S123).

  The area entry / exit determination unit 33 determines whether the user terminal 1 is continuously out of the area and the set area information and the predetermined information of the user terminal 1 stored in the location information storage unit 31. By comparing the position information after the lapse of time, it is detected whether or not the user terminal 1 is outside the predetermined area (step S124). When detecting that the user terminal 1 is outside the predetermined area, the area entry / exit determination unit 33 determines that the user terminal 1 has left the predetermined area (“YES” in step S124).

  On the other hand, when detecting that the user terminal 1 is within the predetermined area (“NO” in step S124), the area entry / exit determination unit 33 suspends the area entry / exit status determination and returns to step S100 again. .

  If the area entry / exit determination unit 33 determines that the user terminal 1 has gone out of the predetermined area ("YES" in step S124), the power supply switching unit 1C is turned on by the same control as in the first embodiment. Then, the cutoff of the power supply from the power supply unit 1A to the function unit 1B is released, and the power is supplied from the power supply unit 1A to the function unit 1B (step S130). As a result, the user can use the main functions of the user terminal 1 (the functions of the functional unit 1B such as the call function and the mail function).

  Subsequent steps are the same as in the first embodiment.

  When a user enters or exits a predetermined area in a short time, it does not make much sense to switch the power supply state according to the area entry / exit situation, and the last power supply state is maintained. That is true. In the second embodiment, the area entry / exit determination unit 33 determines that the user has entered the area only after detecting that the user is continuously in the area for a predetermined period. Therefore, when the user once enters the area and then enters and exits the area, the power supply control unit 12 does not release the interruption of the supply of power from the power supply unit 1A to the functional unit 1B. And the power supply remains off. Further, the area entry / exit determination unit 33 determines that the user has left the area only after detecting that the user is continuously outside the area for a predetermined period. Therefore, when the user once goes out of the area and then enters and exits the area, the power supply control unit 12 does not interrupt the supply of power from the power supply unit 1A to the function unit 1B. , Power remains supplied.

As described above, in the second embodiment, the area entry / exit determination unit 33 compares the area information with the location information, detects whether the user terminal 1 is in the area, and When the user terminal 1 is detected to be in the area, and when the user terminal 1 is detected to be in the area in the detection after a lapse of a predetermined period from the detection, the user terminal 1 is moved to the area. When it is determined that the user terminal 1 is out of the area, it is detected that the user terminal 1 is out of the area, and when the user terminal 1 is detected out of the area in the detection after a predetermined period has elapsed since the detection, It is determined that the user terminal 1 is out of the area.
With this configuration, the state of power supply to the functional unit 1B can be appropriately switched.

  Hereinafter, the configuration of the power supply control system 200 according to the third embodiment of the present invention will be described with reference to FIG.

  The configuration of the power supply control system 200 according to the third embodiment shown in FIG. 4 is different from the configuration of the power supply control system 100 according to the first embodiment (see FIG. 1). This is the point that the unit 35 is provided. Therefore, in the following, among the configurations of the power supply control system 200, the same configurations as those of the power supply control system 100 according to the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The map information section 35 stores map information. The map information includes road information, building information, and the like. The map information is stored in the map information unit 35 by being downloaded in advance from a medium that provides the map information.

  Next, the step of setting area information (step S20) in power supply control system 200 will be described.

  When the power supply control system 200 is started, the setting screen of the area information stored in the monitor terminal 2 in advance is displayed on the display unit 2A of the monitor terminal 2 under the control of the display control unit 22. The displayed setting screen reflects the map information stored in the map information section 35. That is, a map is displayed on the display unit 2A, and area information can be set from the map.

  The monitor operates the input unit 2B (for example, a touch panel) to select a facility or the like to be set as area information from the setting screen on which the map information is reflected (step S20). Then, the selected facility is set as area information in the area information setting unit 21 (step S30).

  With this configuration, the monitor can easily set the area information. Also, the monitor can set the area information without knowing the address or the like. Also, as in the first embodiment, when setting the area information by inputting a radius, even when it is actually desired to set a school as the area information, a range other than the school is also included as the area information. On the other hand, by setting the area information from the setting screen on which the map information is reflected as in the second embodiment, the school site itself can be set as the area information.

As described above, the power supply control system 200 according to the third embodiment includes the map information unit 35 that stores map information, and the area information setting unit 21 performs processing on the map information stored in the map information unit 35. The area information is set based on the area information.
With this configuration, it is possible to easily set the area information.
