  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)

  FIG. 3 shows a priority data table according to the first embodiment of the present invention.

  Furthermore, FIG. 4 shows the block diagram 2 of the energy remaining amount notification system in the first embodiment of the present invention.

  In FIG. 1, an authentication terminal 100, a portable terminal 110, and a position information providing device 120 constitute a remaining energy notification system.

  The authentication terminal 100 includes an authentication terminal energy source 101, an authentication terminal energy remaining amount measuring unit 102 that measures the remaining amount of the authentication terminal energy source 101, and an authentication terminal notification unit 103 that notifies that the remaining energy level is below a certain level. And an authentication terminal display unit 104 that displays the remaining amount of energy, an authentication terminal transceiver 105 that communicates with the mobile terminal 110, and an authentication terminal control unit 106 that controls the authentication terminal.

  The portable terminal 110 includes a portable terminal energy source 111, a portable terminal energy remaining amount measuring unit 112 that measures the remaining amount of the portable terminal energy source 111, and a portable terminal notification unit 113 that notifies that the remaining energy level is below a certain level. The mobile terminal position information acquisition means 118 for acquiring the position information of the mobile terminal, the mobile terminal calculation means 117 for performing calculation based on the remaining energy and the position information, and the control of the mobile terminal based on the results of the mobile terminal calculation means 117 The portable terminal control means 116 to perform, the portable terminal transceiver 115 to communicate with the authentication terminal 100, and the portable terminal display means 114 to display the remaining amount of energy.

  A location information providing device 120 that provides location information to the authentication terminal 100 and the portable terminal 110 includes a communication device 122 that communicates with the authentication terminal 100 and the portable terminal 110, a location information holding unit 123 that holds map information, and an energy source charge or It comprises a supply station information holding means 121 for holding information on supply stations that can be exchanged or newly purchased, and a position information calculation means 124 for calculating a distance between the position information and the supply station information.

  About the remaining energy alerting | reporting system comprised as mentioned above, the operation | movement and an effect | action are demonstrated below using FIGS. 1-3.

  Here, the operation when the energy source is a secondary battery and the remaining battery level of the authentication terminal 100 decreases will be described. However, the same operation is performed when the remaining battery level of the mobile terminal 110 decreases.

  Here, it is assumed that only the portable terminal 110 can acquire the position information and change the communication interval.

  First, the authentication terminal 100 and the mobile terminal 110 perform authentication communication. Here, the authentication communication is communication periodically performed to limit the functions of the mobile terminal 110 according to the distance between each other, and the distance between each other is grasped based on the strength of the signal at the time of reception.

  When the distance is a certain distance or more, the mobile terminal 110 is restricted in function, and when the distance is less than a certain value, the function restriction of the mobile terminal 110 is released.

  Next, in S1, the authentication terminal energy remaining amount measuring means 102 periodically measures the remaining energy of the authentication terminal energy source 101. This measurement result is transmitted from the authentication terminal 100 to the mobile terminal 110.

  The authentication terminal remaining energy measuring means 102 determines whether or not the remaining energy measured in S2 is equal to or lower than a threshold level.

  If it is not lower than the threshold level, the authentication communication is repeated. If the threshold level is lower than the threshold level, either or both of the notification means of the authentication terminal 100 and the portable terminal 110 notify that the threshold level is exceeded. To do. At this time, the authentication terminal notifying unit 106 and the portable terminal notifying unit 113 can notify using any one of sound, light, vibration, or a combination of two or more.

  In S3, the location information of the user is acquired by the mobile terminal location information acquisition means 118. At this time, the mobile terminal 110 can be a terminal equipped with a GPS function, the position information providing device can be a GPS satellite, and the position information can be acquired from the Internet or a communication network for mobile devices.

  In S4, the position information calculation unit 120 performs calculation. The location information providing device 120 stores a store in which energy sources can be purchased, a store that can be charged, a store that can be rented, and a store that can be exchanged in the supply station information holding unit 121. The current position of the portable terminal 110 can be acquired by communicating with the portable terminal 110 and the communication device 122, and the distance from the point to the supply station held in the supply station information holding unit 121 is also the position information. It can be calculated by the calculation means 124.

  The distance calculated in S5 is transmitted from the position information providing device 120 to the portable terminal 110.

  In S6, the mobile terminal calculation means 117 calculates the time required from the current position of the user to the supply station. For example, the mobile terminal 110 is provided with an acceleration sensor to measure the traveling speed, and based on the distance traveled from the position information providing device 120, the time to the supply station is calculated, walking, bicycle, car, etc. It is also possible to perform the calculation at the set speed by providing the advance speed of the item in advance and selecting any one by the portable terminal display means 114.

  This calculation can also be performed by the position information providing device 120.

  Next, in S7, it is selected whether or not to change the communication interval.

  When changing, the calculation which determines a new communication interval is performed in S8. For example, the time to the supply station is 1 hour, the remaining energy is 0.01 mAh, and the current consumption during authentication communication is 10 mA. Here, the remaining energy is the amount excluding the current required during standby.

  In this case, a new communication interval is calculated as follows.

(1) The time for which communication is possible is calculated.
0.01 mAh / 10 mA = 0.001 h⇒3.6 seconds.

(2) The communication interval is calculated (one communication time is set to 10 milliseconds).
3.6 sec / 10 msec = 360 times 1 h / 360 = 10 sec.

  As described above, it is possible to continue the authentication communication for one hour by extending the communication interval to once every 10 seconds. Then, at this interval, the portable terminal control means 116 changes in S9.

  Next, new communication interval information is transmitted to the authentication terminal 100 in S14. In S15, the authentication terminal control means 106 changes the communication interval to a new communication interval, and the authentication terminal 100 and the mobile terminal 110 can communicate with each other at a new communication interval.

  When the communication interval is not changed in S7, the function restriction is applied to the portable terminal 110 in S10.

  As in the case of changing the communication interval in S11, the mobile terminal calculation means 117 calculates the power that needs to be reduced using the time to the supply station, the remaining energy, and the power consumption during communication.

  For example, the time to the supply station is 1 hour, the remaining energy is 0.5 mAh, and the current consumption during authentication communication is 10 mA. Here, the remaining energy is the amount excluding the current required during standby.

  In this case, a new communication interval is calculated as follows.

(1) The energy consumed in the current communication interval (4 seconds) is calculated (one communication time is set to 10 milliseconds).
1h / 4sec * 10msec = 9sec⇒0.0025h
10 mA * 0.0025 h = 0.025 mAh.

(2) Calculate usable energy other than authentication communication.
0.5 mAh-0.025 mAh = 0.475 mAh.

(3) The usable time of each function is calculated with the remaining energy.
Camera: 0.475 mAh / 80 mA = 21.375 seconds Call: 0.475 mAh / 100 mA = 17.1 seconds Mail: 0.475 mAh / 50 mA = 34.2 seconds Game: 0.475 mAh / 200 mA = 8.55 seconds 0.475 mAh / 20 mA = 85.5 seconds.

  If each function is used for the above time, the current communication interval cannot be maintained.

  Therefore, the function restricted in S12 is selected by the portable terminal control means 116 based on the priority order.

  As shown in FIG. 3, the priority order is provided for each function such as a game, mail, and telephone call, and is restricted from a function with a low priority order.

  Here, the priority order will be described in detail.

  The priorities are determined based on one or more of the power consumption, usage frequency, and user's intention of the functions of the mobile terminal 110.

  For example, the priority order in FIG. 3A is determined based on the usage frequency. The daily usage frequency of each function is counted by the portable terminal 110, and the higher the usage frequency, the higher the priority and the less the restriction.

  Here, calling means making or receiving a call and talking, and receiving means that a mobile phone is in a state where a call can be received. When a call is received, sound, light, vibration from the mobile terminal Use one or more of these to let you know and if you can't receive it, leave a message.

  For example, when the call function is restricted and the incoming call is not restricted, the user can know that there is a call, but cannot receive or make a call.

  Next, when the incoming function is restricted and the call is not restricted, the user can make a call but cannot answer the incoming call.

  The mail indicates both mail transmission and reception. It is also possible to treat the transmission / reception function as two different functions.

  When priorities are determined based on a plurality of items, for example, power consumption and usage frequency, each function can determine the priorities in the respective items, and the priorities can be determined based on the sum of the priorities.

  For example, when based on power consumption, as shown in FIG. 3B, a function with higher power consumption is restricted earlier. That is, the higher the power consumption, the lower the priority.

  When the usage frequency and power consumption are taken into consideration, the priority order of the cameras is 4, which is a total of 1 and 3. The total number of calls is 2 and 4 is 6, the total number of e-mails is 3 and 2, and the total number of games is 9, the total of 4 and 5, and the total number of incoming calls is 6.

  That is, the priority order is camera, mail, call and incoming call, and game.

  When there are two or more functions having the same priority, it is possible to select which one the user wants to limit or to set item priorities as in the case of the call and the incoming call.

  For example, if the priority of usage frequency is increased for power consumption and usage frequency, the priority of usage frequency is higher for calls and incoming calls.

  For example, when the incoming call function is restricted, it is notified from the portable terminal notification means 113 in blue color so that the incoming call does not occur. As a result, it is possible to reduce the current consumed when receiving an incoming call.

  Then, the portable terminal control means 116 limits the function selected in S13.

  As described above, in the present embodiment, the mobile terminal 110 and the authentication terminal 100 are driven as energy sources, and the mobile terminal 110 and the authentication terminal 100 that performs wireless communication with the mobile terminal 110 are connected to each other according to the distance from each other. In the authentication communication system that restricts the function to the authentication terminal 100, the authentication terminal 100 is based on the location information acquired by the authentication terminal location information acquisition unit 108 and the remaining energy level measured by the authentication terminal energy level measurement unit 102. The communication interval between the authentication terminal 100 and the mobile terminal 110 is limited, or both are performed.

  As a result, since the operation of reducing the power consumption is performed based on the user position information and the remaining energy, it is possible to prevent the energy from being cut off until the energy source is supplied.

  It is also possible to perform calculations in consideration of temperature, season, etc.

  For example, when the temperature is 5 ° C or below, or from November to February (variable depending on the location), the remaining amount of energy runs out earlier than the time when the temperature is high, so the authentication communication interval is expanded or the authentication communication interval is changed Can be raised.

  Also, if you are in the city center due to location information, the congestion rate of people is high, so if you lengthen the authentication communication interval, you may not notice immediately if you are stolen, so priority is given to function restrictions without changing the authentication communication interval Can also be done.

  Conversely, if you are in a place with low population density, you can increase the communication interval. Also, when the remaining energy level falls below a certain level, the authentication communication interval is changed, but there is a high possibility that the energy supply location is far away in the countryside. It is also possible to change it with this.

  Further, in the present embodiment, the portable terminal position information acquisition unit 118, the portable terminal calculation unit 117, and the portable terminal control unit 116 are provided only in the portable terminal 110. However, as shown in FIG. It is also possible to provide only the authentication terminal 100.

  In the present embodiment, the function restriction of the mobile terminal 110 has been described, but the function restriction of the authentication terminal can also be performed.

  For example, when the remaining amount of energy falls below a certain level, the power of the authentication display means 104 can be turned off. In addition, when the authentication terminal notification means 103 notifies using light, sound, or vibration, one or two of the three are limited, or one is limited when the remaining energy level is below a certain level, and is even lower. It is also possible to limit the other below the level.

  Note that the means described in this embodiment causes hardware resources such as a CPU (or microcomputer), a RAM, a ROM, a storage / recording device, an electrical / information device including an I / O, a computer, a server, and the like to cooperate. You may implement with the form of a program. In the form of a program, new functions can be easily distributed / updated and installed by recording them on a recording medium such as magnetic media or optical media or distributing them using a communication line such as the Internet.

  As described above, since the remaining energy notification system according to the present invention can be held until the user reaches a place where the energy source can be charged or replenished, the in-vehicle keyless entry system or the electronic key of the electronic lock can be used. It can also be applied to other uses.
