  Hereinafter, embodiments will be described with reference to the drawings.

  FIG. 1 shows an embodiment of a monitoring device, a monitoring system, and a monitoring method. In FIG. 1, a monitoring system 100 includes a monitoring device 101 connected to a network 103 that can communicate with a mobile terminal 102. For example, the monitoring device 101 is installed in a communication center that controls communication of the mobile terminal 102 and has a function of monitoring the remaining charge capacity of the battery 102 c of the mobile terminal 102. Note that the communication center may have a function of making a notification to a government office having jurisdiction over the residence of the owner of the mobile terminal 102 or a relative of the owner when receiving an emergency call from the mobile terminal 102.

  For example, the mobile terminal 102 is a smartphone, a feature phone, or a tablet terminal that can be connected to the network 103 that is a communication line for a mobile phone. The network 103 may include a computer network such as the Internet including a wireless LAN (Local Area Network) environment in addition to a cellular phone communication line (wireless network).

  The monitoring apparatus 101 includes a control unit 101a, a reception unit 101b, a transmission unit 101c, and a storage unit 101d. The control unit 101a includes a processor 101e, a first calculation unit 101f, a second calculation unit 101g, an extraction unit 101h, and a determination unit 101i. The control unit 101a has functions of controlling operations of the reception unit 101b and the transmission unit 101c, accessing the storage unit 101d, and controlling the operation of the entire monitoring apparatus 101.

  For example, the processor 101e is a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit) that operates by executing a program, and controls the operation of each element in the monitoring apparatus 101. The first calculation unit 101f calculates the moving speed of the user who owns the mobile terminal 102 as described with reference to FIG. As illustrated in FIGS. 2 and 6, the second calculation unit 101 g can use the mobile terminal 102 based on the movement speed of the user calculated by the first calculation unit 101 f and the position of the mobile terminal 102. To calculate the range in which the user can move. The extraction unit 101h extracts the location of the charger of the mobile terminal 102 that exists in the movable range calculated by the second calculation unit 101g. As described with reference to FIGS. 6 and 7, the determination unit 101 i determines battery deterioration when the rate of decrease in the charging capacity of the battery 102 c of the mobile terminal 102 exceeds the reference speed. For example, the first calculation unit 101f, the second calculation unit 101g, the extraction unit 101h, and the determination unit 101i are executed by the processor 101e executing a program, but may be realized by hardware.

  For example, the control unit 101a is a computer device such as a server, and controls the overall operation of the monitoring device 101 by the processor 101e executing a program. An example of the operation of the control unit 101a is shown in FIGS.

  The receiving unit 101b receives various types of information transmitted from the mobile terminal 102 based on control by the control unit 101a. For example, the information received from the mobile terminal 102 includes position information indicating the position of the mobile terminal 102, battery information indicating the remaining battery capacity of the mobile terminal 102, and charging information indicating the charging state of the mobile terminal 102. The transmission unit 101c transmits information to the mobile terminal 102 based on control by the control unit 101a. For example, the information transmitted to the mobile terminal 102 includes information on a map to be displayed on the display 102e of the mobile terminal 102, and information instructing output of an alarm prompting charging.

  For example, the storage unit 101d is a dynamic random access memory (DRAM) or a hard disk drive (HDD), stores a program executed by the processor 101e, and stores information necessary for the operations shown in FIGS. To do. The control unit 101a writes information received by the receiving unit 101b and information obtained by processing the received information in the storage unit 101d. In addition, the control unit 101a transmits information obtained by processing the information stored in the storage unit 101d to the mobile terminal 102 via the transmission unit 101c. Then, the control unit 101a manages information such as the travel route of the user who owns the mobile terminal 102 and, together with an alarm instruction that prompts charging when the remaining battery capacity of the mobile terminal 102 has decreased to a predetermined amount. The mobile terminal 102 is notified of information indicating the location where the charger is located.

  The portable terminal 102 includes a processor 102a, a wireless communication unit 102b, a battery 102c, a memory 102d, a display 102e, a speaker 102f, and an operation unit 102g.

  The portable terminal 102 controls the operation of the entire portable terminal 102 by the processor 102a executing the program. For example, the processor 102a is a CPU that operates by executing a program. The processor 102a communicates with the monitoring apparatus 101 via the wireless communication unit 102b. The processor 102a monitors a change in the charging capacity of the battery 102c by executing a program, and notifies an alarm via at least one of the display 102e and the speaker 102f according to information from the monitoring device 101. Further, the processor 102a stores information input by the user of the portable terminal 102 through the operation unit 102g in the memory 102d.

  The wireless communication unit 102 b performs wireless processing such as information transmission processing to the network 103 and information reception processing from the network 103. For example, the battery 102c is a rechargeable lithium ion battery. For example, the memory 102d is a DRAM or a flash memory, stores a program executed by the processor 102a, and stores information necessary for the operations shown in FIGS. For example, the display 102e is a liquid crystal display, and displays a screen that guides the operation of the mobile terminal 102, or displays an alarm screen that indicates a shortage of the remaining charge capacity of the battery 102c. The speaker 102f outputs an operation sound notifying the operation of the operation unit 102g, an alarm sound or an alarm sound indicating that the remaining capacity of the battery 102c is insufficient. For example, the operation unit 102g has input keys such as numerals and alphabets, operation buttons, and the like, and is used to input a telephone number when the mobile terminal 102 is in a call and to input registration information shown in FIG.

  For example, the mobile terminal 102 has a GPS (Global Positioning System) receiver, and acquires position information of the mobile terminal 102 based on a signal from a GPS satellite received by the receiver. Note that the mobile terminal 102 may acquire the position information of the mobile terminal 102 according to the signal strength communicated with the base station of the mobile phone communication line. The mobile terminal 102 may include an acceleration sensor. By using the acceleration sensor, even when the signal from the GPS satellite is interrupted, it is possible to update the position information that changes as the user carrying the mobile terminal 102 moves. Examples of the operation of the mobile terminal 102 are shown in FIGS.

  FIG. 2 shows an outline of the operation of the monitoring system 100 shown in FIG. In this example, the user who has the mobile terminal 102 is at the center of the circles D1, D2, and D3, as indicated by the black circles. In FIG. 2, circles D1, D2, and D3 indicate that when the charging capacity of the battery 102c of the mobile terminal 102 is reduced to a predetermined amount, the user who owns the mobile terminal 102 determines the charging capacity of the battery 102c of the mobile terminal 102 The distance that can be moved without emptying is shown by safety level. A circle D1 indicates a distance that the user can move in a state in which the charging capacity is sufficiently secured. A circle D2 indicates a distance that the user can move without emptying the charging capacity. A circle D3 indicates a distance at which the charging capacity may become empty during the movement of the user. That is, an annular area surrounded by the circle D2 and the circle D3 indicates an area where the charging capacity may be emptied during the movement of the user. In the following description, the user who has the mobile terminal 102 is also simply referred to as a user.

  FIG. 2A shows a case where the moving speed of the user is higher than that in FIG. Therefore, in FIG. 2A, the distance that the user can move is longer than that in FIG. 2B, and the sizes of the circles D1, D2, and D3 are larger than those in FIG. 2B, respectively. . The moving speed of the user is calculated by the monitoring apparatus 101 based on the user position information received from the mobile terminal 102 at a predetermined frequency. The sizes of the circles D1, D2, and D3 are calculated by the monitoring device 101 using information indicating the moving speed of the user when it is detected that the charging capacity of the battery 102c of the mobile terminal 102 has decreased to a predetermined amount. The For example, the monitoring device 101 calculates the size of the circles D1, D2, and D3 when the charging capacity of the battery 102c is reduced to one third of the fully charged state.

  The position of the user's home 104 of the mobile terminal 102 indicated by a double circle in FIG. 2 is registered in advance in the monitoring apparatus 101. It is assumed that a charger for the mobile terminal 102 is installed at home 104. In addition, the monitoring device 101 determines the position of the facility 105 (105a, 105b, 105c, 105d) where the charger of the mobile terminal 102 indicated by the triangle mark in FIGS. 2 (a) and 2 (b) is installed. Obtained in advance from the map information of the system.

  When the monitoring apparatus 101 detects that the charging capacity of the battery 102c of the mobile terminal 102 has decreased to a predetermined amount based on information received from the mobile terminal 102, the monitoring apparatus 101 uses information indicating the movement speed of the user. , The sizes of the circles D1, D2, and D3 are calculated. Then, the monitoring apparatus 101 displays an alarm screen for prompting charging on the display of the mobile terminal 102 or information for outputting an alarm sound or alarm sound for prompting charging from the speaker 102 f of the mobile terminal 102 to the mobile terminal 102. Send. In addition, the monitoring device 101 displays, for example, the location (triangle mark and double circle) where the charger of the mobile terminal 102 is installed and the circles D1, D2, and D3 on the map displayed on the display 102e of the mobile terminal 102. Information for indicating is transmitted to the mobile terminal 102. At this time, as shown in FIG. 2, the monitoring apparatus 101 may display on the display 102e of the mobile terminal 102 so that the place where the charger is installed can be distinguished between the inner area and the outer area of the circle D2. (In this example, it is distinguished by a solid line and a broken line).

  For example, the higher the moving speed of the user, the longer the distance that the user can reach before the remaining capacity of the battery 102c runs out, and it is included in each of the circles D1, D2, and D3 calculated by the monitoring device 101. The area on the map will be larger. In the example shown in FIG. 2A, the facilities 105a, 105b, 105c and the home 104 except the facility 105d are located inside the circle D2. In this case, the monitoring apparatus 101 transmits an instruction to display the facilities 105 a, 105 b, 105 c and the home 104 with solid lines and to display the facility 105 d with broken lines to the mobile terminal 102.

  On the other hand, the lower the moving speed of the user, the shorter the distance that the user can reach before the remaining capacity of the battery 102c runs out, and it is included in each of the circles D1, D2, and D3 calculated by the monitoring device 101. The area on the map will be smaller. In the example shown in FIG. 2B, the facilities 105b and 105d and the home 104 are located outside the circle D2, and the facilities 105a and 105c are located inside the circle D2 on the map. In this case, the monitoring apparatus 101 transmits an instruction to display the facilities 105a and 105c with solid lines and display the facilities 105b and 105d and the home 104 with broken lines to the mobile terminal 102. Note that the monitoring apparatus 101 may prohibit display of a charger installed on a map outside the circle D2 on the map.

  The user moves to the place where the charger is installed (the facilities 105a and 105c in FIG. 2B) based on the alarm for prompting charging and the circle D2 displayed on the map on the display 102e of the portable terminal 102. Then, the battery 102c of the portable terminal 102 is charged.

  Note that the monitoring apparatus 101 may set a short movable distance on an uphill or a staircase, and may set a long movable distance on a downhill. In this case, the monitoring apparatus 101 may display an ellipse or a polygon indicating the movable distance on the display 102e of the mobile terminal 102 together with the map instead of the circles D1, D2, and D3 indicating the movable distance. . In addition, the monitoring apparatus 101 may change the setting of the distance that can be moved along a road or terrain on the map, and display it on the display 102e of the mobile terminal 102 together with the map. For example, the monitoring apparatus 101 deforms a shape such as an ellipse or a polygon indicating a movable distance so as to be long along a road or the like and short along a forest or the like, and displays it on the display 102e of the mobile terminal 102 together with a map. May be.

  FIG. 3 shows an example of the use start process of the mobile terminal 102 and the process of the monitoring apparatus 101 shown in FIG. 3, steps S101 to S103 indicate an initial setting operation of the mobile terminal 102, and steps S201 to S204 indicate a user registration operation of the monitoring apparatus 101. In FIG. 3, the initial setting operation of the mobile terminal 102 is started when the user downloads the application program that realizes the operation shown in FIG. 2 to the mobile terminal 102 and the downloaded application program is first activated. . That is, steps S101 to S103 are realized by the processor 102a built in the portable terminal 102 executing the application program first.

  In step S101, the mobile terminal 102 accepts user registration information that is user registration information input by the user. The user registration information includes the model of the mobile terminal 102, the address of the user's home 104, the date on which the use of the mobile terminal 102 was started, and the like. For example, the mobile terminal 102 treats the day when the use of the mobile terminal 102 is started as the day when the use of the battery 102c of the mobile terminal 102 is started. Note that the portable terminal 102 also executes steps S101 to S103 when the application program is first activated after the battery 102c of the portable terminal 102 is replaced. In this case, the mobile terminal 102 treats the date when the battery 102c is replaced as the date when the use of the battery 102c of the mobile terminal 102 is started.

  Next, in step S102, the mobile terminal 102 transmits the user registration information input by the user in step S101 to the monitoring apparatus 101 via the wireless communication unit 102b.

  Next, in step S <b> 103, the mobile terminal 102 determines whether a registration completion notification for user registration information has been received from the monitoring apparatus 101 in response to transmission of user registration information. When the mobile terminal 102 determines that the registration completion notification of the user registration information from the monitoring apparatus 101 has been received, the mobile terminal 102 ends the use start process. The mobile terminal 102 repeats the process of step S103 until receiving the registration completion notification of the user registration information from the monitoring apparatus 101. When the mobile terminal 102 receives the registration completion notification of the user registration information from the monitoring apparatus 101, the use starts. The process ends. Thereafter, when the user of the mobile terminal 102 activates an application program that realizes the operation shown in FIG. 2, the mobile terminal 102 executes the process shown in FIG. 4. Note that the portable terminal 102 may automatically start the process illustrated in FIG. 4 after completing the use start process in step S103.

  On the other hand, in step S201, the monitoring apparatus 101 receives user registration information from the mobile terminal 102 via the receiving unit 101b. Note that the processing in steps S201 to S204 is realized by the processor 101e built in the control unit 101a executing a program.

  Next, in step S202, the control unit 101a registers the acquired user registration information by writing it in the storage area of the user registration information assigned to the storage unit 101d.

  Next, in step S <b> 203, the monitoring apparatus 101 transmits a user registration information registration completion notification to the mobile terminal 102. The user registration process is completed by the process of step S203.

  Next, in step S204, after completing the user registration process, the monitoring apparatus 101 activates a processing routine for monitoring the charge capacity of the battery 102c of the mobile terminal 102 shown in FIG. An example of the processing routine of the monitoring operation of the charging capacity of the battery 102c is shown in FIG.

  FIG. 4 shows an example of the operation of the mobile terminal 102 after completion of the use start process shown in FIG. For example, the mobile terminal 102 starts the process in FIG. 4 based on the application program that realizes the operation shown in FIG. 2 being activated by the user. For example, the process illustrated in FIG. 4 is realized by the processor 102a built in the mobile terminal 102 executing the program.

  In step S301, the mobile terminal 102 determines whether or not the battery 102c is being charged. If the mobile terminal 102 determines that the battery 102c is being charged, the process proceeds to step S309. On the other hand, if the mobile terminal 102 determines that the battery 102c is not being charged, the process proceeds to step S302.

  In step S <b> 302, the mobile terminal 102 operates a built-in GPS receiver to acquire position information indicating the current position of the mobile terminal 102. The location information may be obtained from a base station of a mobile phone line.

  Next, in step S <b> 303, the mobile terminal 102 determines whether or not the user is out of the office by determining whether or not the mobile terminal 102 is in the user's home 104. For example, whether or not the user is out is determined based on whether or not the position information acquired in step S302 is within a predetermined range from the position indicated by the address of the user's home 104 registered in step S101. If the mobile terminal 102 determines that the user is out, the process proceeds to step S304. On the other hand, if the mobile terminal 102 determines that the user is at home 104, the process proceeds to step S <b> 312.

  In step S <b> 304, the mobile terminal 102 acquires location information of the mobile terminal 102. The acquired position information is stored in the memory 102d built in the portable terminal 102.

  Next, in step S305, the mobile terminal 102 determines whether or not the position information has been accumulated in the memory 102d, for example, 10 times. If the mobile terminal 102 determines that the acquired position information has been accumulated 10 times, the process proceeds to step S306. On the other hand, if the mobile terminal 102 determines that the acquired position information has not been accumulated 10 times, the process proceeds to step S304.

  The portable terminal 102 repeats the loop of steps S304 and S305 every predetermined time (for example, every minute). Thereby, position information is acquired for every progress of predetermined time. Here, as an example, the mobile terminal 102 accumulates the position information 10 times, but the number of accumulations is not limited to 10 times. Note that, as will be described with reference to FIG. 6, the monitoring apparatus 101 uses the position information accumulated a plurality of times to calculate the moving speed and moving distance of the user.

  In step S306, the mobile terminal 102 notifies the accumulated position information to the monitoring apparatus 101 via the wireless communication unit 102b. The mobile terminal 102 notifies the monitoring apparatus 101 of the location information accumulated 10 times, so that the number of communication between the mobile terminal 102 and the monitoring apparatus 101 can be reduced, and the charging capacity of the battery 102c of the mobile terminal 102 can be reduced. Reduction can be suppressed.

  Next, in step S307, the mobile terminal 102 acquires the remaining charge capacity of the battery 102c.

  Next, in step S308, the mobile terminal 102 notifies the monitoring device 101 of the remaining charge capacity of the battery 102c acquired in step S307 via the wireless communication unit 102b. The notification of the position information to the monitoring apparatus 101 in step S306 described above may be performed in step S308. In this case, the number of communications between the mobile terminal 102 and the monitoring device 101 can be reduced, and a reduction in the charging capacity of the battery 102c of the mobile terminal 102 can be suppressed.

  Next, in step S309, the mobile terminal 102 determines whether or not the state of charge of the mobile terminal 102 has changed. Here, the change in the charging state is one of the change from the charging state of the mobile terminal 102 to the non-charging state and the change of the mobile terminal 102 from the non-charging state to the charging state. If the mobile terminal 102 determines that the state of charge of the mobile terminal 102 has changed, the process proceeds to step S310. On the other hand, if the mobile terminal 102 determines that the state of charge of the mobile terminal 102 has not changed, that is, if the state of charge is maintained or the state of non-charge is maintained, the process proceeds to step S311. .

  In step S310, the mobile terminal 102 notifies the monitoring apparatus 101 of information indicating a change in the charging state of the mobile terminal 102 via the wireless communication unit 102b.

  In step S311, the mobile terminal 102 determines whether an end operation by the user has been received via the operation unit 102g. The ending operation is a power-off operation of the mobile terminal 102, an application program ending operation, or the like. If the mobile terminal 102 determines that the end operation by the user has been received, the mobile terminal 102 ends the application program execution process, and displays information indicating that the application program execution process has ended via the wireless communication unit 102b. Notify On the other hand, when it is determined that the termination process by the user is not accepted, the mobile terminal 102 shifts the process to step S301 and repeats the above process.

  On the other hand, when the user is not going out, in step S312, the mobile terminal 102 acquires the remaining charge capacity of the battery 102c of the mobile terminal 102. The process of step S312 is the same as the process of step S307.

  Next, in step S313, the mobile terminal 102 determines whether or not the remaining charge capacity of the battery 102c of the mobile terminal 102 has decreased to a predetermined amount based on the information acquired in step S312. If the mobile terminal 102 determines that the remaining charge capacity has decreased to a predetermined amount, the process proceeds to step S314. If the mobile terminal 102 determines that the remaining charge capacity has not decreased to the predetermined amount, the process proceeds to step S315. Transition. For example, the predetermined amount is one third of the fully charged state.

  In step S314, the mobile terminal 102 notifies the user of an alarm prompting charging by displaying an alarm screen on the display 102e or outputting a sound or an alarm sound from the speaker 102f. A user who recognizes the alarm at home 104 connects portable terminal 102 to a charger at home 104 and charges battery 102c. When the user is at home 104, the user can be prompted to charge the battery 102 c of the mobile terminal 102 without performing communication between the mobile terminal 102 and the monitoring apparatus 101. Can be used. After the process of step S314, the process proceeds to step S309.

  On the other hand, in step S315, the mobile terminal 102 determines whether or not the current time is, for example, midnight. For example, midnight is 3 am. As an example, the determination as to whether it is midnight is performed based on the time counted by the clock built in the mobile terminal 102. Note that the determination in step S315 may be performed every two days or every three days. If the mobile terminal 102 determines that the current time is midnight, the process proceeds to step S316. On the other hand, if the mobile terminal 102 determines that the current time is not midnight, the process proceeds to step S309.

  Next, in step S316, the mobile terminal 102 acquires the remaining charge capacity of the battery 102c of the mobile terminal 102 twice with a time interval (for example, 30 minutes).

  Next, in step S317, the portable terminal 102 notifies the monitoring apparatus 101 of the amount of change in the remaining charge capacity of the battery 102c acquired twice via the wireless communication unit 102b. As described with reference to FIG. 6, the monitoring apparatus 101 determines the degree of deterioration of the battery 102 c based on the notification from the mobile terminal 102. After the process of step S317, the process proceeds to step S309.

  In this example, since the mobile terminal 102 acquires the remaining charge capacity at midnight when the probability that the user does not use the mobile terminal 102 is higher than the daytime, the battery 102c in the standby state of the mobile terminal 102 is deteriorated. It becomes detectable. By detecting the amount of change in the remaining capacity of the battery 102c during the standby state, the mobile terminal 102 detects the amount of change in the remaining amount of charge capacity while being used by the user. It becomes easy to detect the deterioration of the battery 102c. This is because the amount of power consumed by the user using the mobile terminal 102 is not included in the amount of change in the remaining charge capacity.

  Here, the mobile terminal 102 may execute at least steps S315 to S317 in the processing illustrated in FIG. 4 even in a standby state other than midnight. The determination of whether or not it is in the standby state is performed based on, for example, the usage rate of the processor 102a. As an example, the mobile terminal 102 determines whether the mobile terminal 102 is in a standby state based on whether the usage rate of the processor 102a of the mobile terminal 102 is 10% or less. Even in a standby state other than midnight, by detecting the amount of change in the remaining charge capacity of the battery 102c, for example, even in the portable terminal 102 that is often used at midnight, the battery 102c in the standby state is deteriorated. It becomes detectable.

  Note that when the deterioration of the battery 102c of the mobile terminal 102 is not detected, the processes of steps S315, S316, and S317 are omitted. Further, when the mobile terminal 102 is at home 104 and no alarm is generated due to insufficient charging of the battery 102c, the processes of steps S312, S313, and S314 are omitted.

  FIG. 5 shows an example of the interrupt processing operation of the mobile terminal 102 shown in FIG. When receiving information related to the alarm from the monitoring apparatus 101, the mobile terminal 102 starts the interrupt processing operation illustrated in FIG. 5 separately from the processing illustrated in FIG. Information relating to the alarm transmitted from the monitoring apparatus 101 to the mobile terminal 102 will be described with reference to FIG.

  For example, the mobile terminal 102 receives information indicating issuance of an alarm prompting charging of the battery 102c, information indicating a chargeable location, or information indicating issuance of alarm indicating deterioration of the battery 102c, which is transmitted from the monitoring device 101. When received, the processing of the interrupt operation is started. The interrupt processing shown in FIG. 5 is realized, for example, when the processor 102a built in the mobile terminal 102 executes a program.

  In step S <b> 401, the mobile terminal 102 determines whether information indicating issuance of an alarm prompting charging of the battery 102 c is received from the monitoring device 101. If the mobile terminal 102 determines that it has received information from the monitoring apparatus 101 indicating that an alarm issuing the battery 102c to be charged, the process proceeds to step S402. On the other hand, if the mobile terminal 102 determines that it has not received from the monitoring apparatus 101 information indicating the issuance of an alarm prompting charging of the battery 102c, the process proceeds to step S403.

  In step S402, the mobile terminal 102 displays an alarm prompting charging on the built-in display 102e, or outputs an alarm sound or sound prompting charging from the built-in speaker 102f, or displays an alarm display and an alarm sound. Do both outputs.

  As described above, in the present embodiment, when the user has the portable terminal 102 and the remaining capacity of the battery 102c is insufficient while going out, the portable terminal 102 receives information from the monitoring device 101. Based on this, an alarm prompting charging is displayed. Based on the alarm, the user can charge the mobile terminal 102 with the charger of the home 104 or the nearest facility 105, so that the remaining charge capacity of the battery 102c of the mobile terminal 102 is lost even when the user goes out. Can be suppressed.

  On the other hand, in step S403, the mobile terminal 102 transmits information indicating the location of the charger transmitted from the monitoring apparatus 101, and information indicating the sizes of the circles D1, D2, and D3 displayed on the display 102e of the mobile terminal 102. Is received. If the mobile terminal 102 determines that information indicating the location of the charger and information indicating the sizes of the circles D1, D2, and D3 displayed on the display 102e have been received, the process proceeds to step S404. On the other hand, if it is determined that the mobile terminal 102 has not received information indicating the location of the charger and information indicating the size of the circles D1, D2, and D3 displayed on the display 102e of the mobile terminal 102, The process proceeds to step S405.

  In step S404, the mobile terminal 102 receives information indicating the location of the charger and information indicating the size of the circles D1, D2, and D3 on the display 102e, a map indicating the current location of the user, The place where the charger is located and the circles D1, D2, and D3 are displayed. After step S404, the process proceeds to step S405. As an example, the mobile terminal 102, as shown in FIG. 2, together with an alarm prompting charging in step S402, a map including the current location of the user, a place where the charger is installed in the area inside the circle D2, and a circle D1-D3 are displayed on the display 102e.

  As described above, in this embodiment, the user can grasp the place where charging is possible based on the current position of the user received from the monitoring apparatus 101 and the moving speed of the user. For this reason, even when the user goes out, the battery 102c can be charged before the remaining charge capacity of the battery 102c of the mobile terminal 102 runs out.

  On the other hand, in step S <b> 405, the mobile terminal 102 determines whether information indicating issuance of an alarm indicating deterioration of the battery 102 c has been received from the monitoring apparatus 101. If it is determined that the mobile terminal 102 has received information indicating the issuance of an alarm indicating the deterioration of the battery 102c from the monitoring device 101, the process proceeds to step S406. On the other hand, when it is determined that the mobile terminal 102 has not received information indicating issuance of an alarm indicating the deterioration of the battery 102c from the monitoring device 101, the process is terminated.

  In step S406, the mobile terminal 102 displays an alarm for prompting replacement of the battery 102c on the display 102e based on reception of information indicating the issuance of an alarm, or an alarm sound or sound prompting replacement of the battery 102c from the speaker 102f. Is output. Alternatively, the mobile terminal 102 performs both alarm display and alarm sound output based on reception of information indicating the issuance of an alarm. After step S406, the interrupt process ends.

  Thus, in this embodiment, when the battery 102c of the mobile terminal 102 has deteriorated, the mobile terminal 102 displays an alarm that prompts the user to replace the battery 102c based on the reception of information from the monitoring device 101. For this reason, it is possible to reduce the possibility of the remaining charge capacity remaining due to the deterioration of the battery 102c as compared to the conventional case.

  FIG. 6 shows an example of processing for monitoring the charge capacity of the battery 102c of the mobile terminal 102 activated by the processing in step S204 executed by the monitoring apparatus 101 shown in FIG. The processing illustrated in FIG. 6 is realized by the processor 101e built in the control unit 101a of the monitoring apparatus 101 executing a program.

  In step S501, the control unit 101a reads the user registration information registered in the storage unit 101d in the process of step S202 illustrated in FIG. 3 from the storage unit 101d.

  Next, in step S502, the control unit 101a determines whether various types of information are received from the mobile terminal 102. For example, the various types of information of the mobile terminal 102 include any of the information transmitted from the mobile terminal 102 in steps S306, S308, S310, and S317 illustrated in FIG. That is, for example, the various types of information of the mobile terminal 102 include any one of the position information of the mobile terminal 102, the remaining charge capacity of the battery 102c, the change in the charge state, and the information indicating the change amount of the charge capacity of the battery 102c. When the control unit 101a receives various types of information from the mobile terminal 102, for example, the control unit 101a stores the received information in the storage unit 101d.

  In step S503, the control unit 101a uses the date when the use of the mobile terminal 102 included in the user registration information stored in the storage unit 101d is started as a reference, and the battery 102c of the mobile terminal 102 has been used for two years or more. It is determined whether or not it has elapsed. If the control unit 101a determines that the battery 102c of the mobile terminal 102 has been used for two years or more, the process proceeds to step S514. On the other hand, if the control unit 101a determines that the battery 102c of the mobile terminal 102 has not been used for more than two years, the process proceeds to step S504.

  In step S514, which will be described later, the control unit 101a transmits information indicating the issuance of an alarm prompting replacement of the battery 102c to the portable terminal 102. However, if an alarm that prompts replacement of the battery 102c occurs every time an affirmative determination (Yes) is made in step S503, the user of the mobile terminal 102 may feel inconvenienced. Since the portable terminal 102 can be used even after detecting the deterioration of the battery 102c, the determination in step S503 may be performed every week or every several weeks, for example.

  In step S504, the control unit 101a determines whether or not the battery 102c of the mobile terminal 102 has deteriorated based on the information indicating the amount of change (decrease) in the charge capacity of the battery 102c stored in the storage unit 101d. . That is, the control unit 101a detects the deterioration of the battery 102c when the amount of change in the charging capacity of the battery 102c notified from the mobile terminal 102 in step S317 shown in FIG. 4 is larger than a preset reference value. To do. Here, the change amount of the charge capacity is a decrease amount of the remaining charge capacity acquired by the mobile terminal 102 at intervals of, for example, 30 minutes in step S316 illustrated in FIG. 4 and indicates a decrease rate of the remaining charge capacity. . That is, the monitoring device 101 detects the deterioration of the battery 102c when the rate of decrease in the charging capacity of the battery 102c is faster than the reference rate of decrease that is a predetermined threshold.

  When the control unit 101a detects the deterioration of the battery 102c, the control unit 101a proceeds to step S514. On the other hand, if the battery 102c has not deteriorated, the control unit 101a moves the process to step S505. In addition, when the information on the amount of change in the charging capacity of the battery 102c is not stored in the storage unit 101d, the control unit 101a makes a negative determination (No) in the process of step S505. Further, in step S502, the control unit 101a may make a negative determination (No) in the process of step S504 when the information indicating the change amount of the charge capacity of the battery 102c is not received. The threshold value used for determining the deterioration of the battery 102c will be described with reference to FIG.

  Similarly to the description in step S503, if an alarm that prompts replacement of the battery 102c occurs every time an affirmative determination is made in step S503 (for example, every day), the user of the mobile terminal 102 may feel inconvenienced. is there. For this reason, the determination in step S504 may be performed, for example, every week or every few weeks.

  In step S505, the control unit 101a determines whether or not the mobile terminal 102 is being charged based on information indicating a change in the state of charge of the mobile terminal 102 stored in the storage unit 101d. That is, if the control unit 101a determines that the mobile terminal 102 is being charged based on the notification of the charging state of the battery 102c notified from the mobile terminal 102 in step S310 illustrated in FIG. 4, the process proceeds to step S513. Migrate to On the other hand, if the control unit 101a determines that the mobile terminal 102 is not being charged, the process proceeds to step S506. In addition, when the information which shows the change of a charge condition is not memorize | stored in the memory | storage part 101d, the control part 101a makes affirmation determination (Yes) by the process of step S505. Further, when the control unit 101a does not receive a notification of the state of charge of the battery 102c in step S502, the control unit 101a may make an affirmative determination (Yes) in the process of step S505.

  In step S506, the control unit 101a determines whether or not the user is out based on the information indicating the location information of the mobile terminal 102 stored in the storage unit 101d. That is, if the control unit 101a determines that the user is out based on the location information of the mobile terminal 102 notified from the mobile terminal 102 in step S306 shown in FIG. 4, the process proceeds to step S507. To do. On the other hand, if the control unit 101a determines that the user is not out, the process proceeds to step S513. In addition, when the information which shows the positional information on the portable terminal 102 is not memorize | stored in the memory | storage part 101d, the control part 101a makes a negative determination (No) by the process of step S506. In addition, when it is determined in step S502 that the position information of the mobile terminal 102 has not been received, the control unit 101a may make a negative determination (No) in the process of step S506.

  In step S507, the control unit 101a determines whether or not the charge capacity of the battery 102c of the mobile terminal 102 is sufficient based on the information indicating the remaining charge capacity of the battery 102c stored in the storage unit 101d. That is, the control unit 101 determines whether or not the charge capacity is sufficient based on the remaining charge capacity of the battery 102c notified from the portable terminal 102 in step S308 illustrated in FIG. For example, when the charging capacity of the battery 102c is 1/3 or more, the control unit 101a determines that the charging capacity of the battery 102c is sufficient, and the process proceeds to step S513. On the other hand, for example, when the charging capacity of the battery 102c is less than 1/3, the control unit 101a moves the process to step S508. When information indicating the charging capacity of the battery 102c is not stored in the storage unit 101d, the control unit 101a makes a negative determination (No) in the process of step S507. In addition, in step S502, the control unit 101a may make a negative determination (No) in the process of step S507 when not notified of the charge capacity of the battery 102c.

  In step S508, the control unit 101a calculates the distance traveled by the user per unit time based on the position information of the mobile terminal 102 stored in the storage unit 101d, and obtains the moving speed of the user. For example, the control unit 101a reads the position information for 10 consecutive times received from the mobile terminal 102 from the storage unit 101d based on the process of step S306 illustrated in FIG. To calculate the user's moving speed. Note that the monitoring apparatus 101 may obtain the moving speed of the user using the location information of the mobile terminal 102 and the geographic location information using a geographic information system (GIS).

  Next, in step S509, the control unit 101a carries out the mobile phone based on the information indicating the remaining charge capacity of the battery 102c stored in the storage unit 101d and the moving speed of the user obtained in the process of step S508. The distance (range) in which the user can move while the terminal 102 can be used is calculated. That is, the control unit 101a calculates the distance (range) that the user can move without setting the charging capacity of the battery 102c of the mobile terminal 102 to zero. As shown in FIG. 2, the range in which the user can move, that is, the sizes of the circles D1, D2, and D3 vary according to the moving speed of the user. Note that the control unit 101a may calculate the distance (range) that the user can move while leaving the charge capacity of the battery 102c of the portable terminal 102 as much as the remaining amount capable of making an emergency call.

  Next, in step S510, the control unit 101a searches, for example, a map database in a communication center that controls communication of the mobile terminal 102, and within a predetermined range from the current position of the user, Identify where the charger is located. In addition, when the position (address) of the user's home 104 included in the user registration information is included within a predetermined range from the current position of the user, the control unit 101a charges the battery at the user's home 104. Include the charger in the specified charger.

  For example, the control unit 101a may specify the location of the charger that is within the range of the circle D3 illustrated in FIG. 2, and the location of the charger that is within the region where the circle D3 is extended outward by a predetermined distance. You may specify.

  Next, in step S <b> 511, the control unit 101 a transmits information indicating issuance of an alarm that prompts charging to the mobile terminal 102. Note that, as described in step S402 in FIG. 5, the mobile terminal 102 displays an alarm prompting charging on the built-in display 102e based on reception of information indicating the issuance of the alarm, or is charged from the built-in speaker. Output alarm sounds and sounds to urge you. Alternatively, as described in step S <b> 402 in FIG. 5, the mobile terminal 102 performs both alarm display and alarm sound output.

  Next, in step S512, the control unit 101a displays information indicating the location of the charger specified in step S510 on the mobile terminal 102 and the sizes of the circles D1, D2, and D3 displayed on the display 102e of the mobile terminal 102. Information to be transmitted. Note that, as described in step S404 in FIG. 5, the mobile terminal 102 displays the user's place on the display 102e based on the information indicating the location of the charger and the information indicating the size of the circle D1-D3. A map including the current location, a place with a charger, and circles D1-D3 are displayed.

  As an example, the mobile terminal 102, as shown in FIG. 2, together with an alarm prompting charging, a map including the current location of the user, a place where the charger is installed in the area inside the circle D2, and a circle D1- D3 is displayed on the display 102e.

  Note that the transmission processing to the mobile terminal 102 in steps S511 and S512 may be performed together. In this case, the number of communications between the mobile terminal 102 and the monitoring device 101 can be reduced, and a reduction in the charging capacity of the battery 102c of the mobile terminal 102 can be suppressed.

  Next, in step S513, based on the notification from the mobile terminal 102, the control unit 101a determines whether or not the application program of the mobile terminal 102 is ended or the power of the mobile terminal 102 is turned off. That is, the control unit 101a determines whether or not the user has performed an end operation of the portable terminal 102 in step S311 illustrated in FIG. When it is determined that the end operation of the mobile terminal 102 has been performed, the control unit 101a ends the monitoring operation process. On the other hand, if the control unit 101a determines that the termination operation of the mobile terminal 102 has not been performed, the control unit 101a moves the process to step S501 and repeats the above process.

  On the other hand, in step S <b> 514, the control unit 101 a transmits information indicating issuance of an alarm indicating deterioration of the battery 102 c of the mobile terminal 102 to the mobile terminal 102. Note that, as described in step S406 in FIG. 5, the mobile terminal 102 displays an alarm prompting the replacement of the battery 102c on the display 102e based on reception of information indicating the issuance of the alarm, or from a built-in speaker. Outputs alarm sound and voice prompting replacement of charging. Alternatively, as described in step S406 in FIG. 5, the mobile terminal 102 performs both alarm display and alarm sound output.

  FIG. 7 shows an example of the discharge characteristics of the battery 102c of the mobile terminal 102 shown in FIG. The vertical axis in FIG. 7 indicates the charging capacity of the battery 102c, and the horizontal axis indicates the time after the mobile terminal 102 is charged. For example, characteristics E1, E2, and E3 indicate changes in the charging capacity of the battery 102c in the standby state of the mobile terminal 102. For example, the characteristic E1 indicates a discharge characteristic of the battery 102c immediately after the use of the mobile terminal 102 is started, and the characteristic E2 indicates that the mobile terminal 102 is used for one year in a standard use state, and the battery 102c is slightly deteriorated. It shows the discharge characteristics in the state. For example, the characteristic E3 indicates a discharge characteristic when the battery 102c is deteriorated, and the characteristic E (b) after a predetermined time has elapsed since charging is easier to discharge than the characteristic E (a) immediately after charging.

  As the battery 102c deteriorates, the rate of decrease in charge capacity, which is the amount of discharge per unit time, becomes faster. The decrease rate of the charge capacity is indicated by the slopes of the characteristics E1, E2, and E3. For example, in step S504 in FIG. 6, the control unit 101a determines that the control unit 101a determines that the charge capacity decrease rate, which is the amount of change in the charge capacity of the battery 102c, is higher than the charge capacity decrease rate indicated by the characteristic E3 (b). Determines that the battery 102c of the mobile terminal 102 has deteriorated. That is, the determination condition in step S504 in FIG. 6 is the slope of the characteristic E3 (b), and the control unit 101a determines that the slope indicating the rate of decrease in the charge capacity of the battery 102c is greater than the slope of the characteristic E3 (b). It is determined that the battery 102c has deteriorated.

  As described above, in this embodiment, when the user has the portable terminal 102 and the remaining capacity of the charging capacity of the battery 102c is insufficient while going out, the portable terminal 102 is charged based on reception of information from the monitoring device 101. Display an alarm prompting Based on the alarm, the user can charge the mobile terminal 102 with the charger of the home 104 or the nearest facility 105, so that the remaining charge capacity of the battery 102c of the mobile terminal 102 is lost even when the user goes out. Can be suppressed. Moreover, in this embodiment, the user can grasp | ascertain the place which can be charged based on the user's present position received from the monitoring apparatus 101, and a user's moving speed. For this reason, even when the user goes out, the battery 102c can be charged before the remaining charge capacity of the battery 102c of the mobile terminal 102 runs out. In this embodiment, when the battery 102c of the mobile terminal 102 is deteriorated, the mobile terminal 102 displays an alarm for prompting replacement of the battery 102c based on reception of information from the monitoring apparatus 101. For this reason, it is possible to reduce the possibility of the remaining charge capacity remaining due to the deterioration of the battery 102c as compared to the conventional case.

  FIG. 10 shows an example of the operation of the mobile terminal 102A after the use start process shown in FIG. 9 is completed. The mobile terminal 102A executes steps S304A, S305A, and S306A instead of steps S304, S305, and S306 shown in FIG. The processing excluding steps S304A, S305A, and S306A is the same as that in FIG. Detailed description of the same processing as in FIG. 4 is omitted.

  In step S304A, the mobile terminal 102A acquires position information based on a signal from a GPS satellite, and counts the number of steps of the user per predetermined time (for example, 1 minute). The acquired position information and step number information indicating the number of steps of the user per predetermined time are stored in the memory 102d built in the mobile terminal 102A.

  Next, in step S305A, the mobile terminal 102 determines whether the position information and the step count information have been accumulated in the memory 102d, for example, 10 times. If the mobile terminal 102 determines that the acquired position information and step count information have been accumulated 10 times, the process proceeds to step S306A. On the other hand, if the mobile terminal 102A determines that the acquired position information and step count information have not been accumulated 10 times, the process proceeds to step S304A.

  The portable terminal 102A repeats the loop of steps S304A and S305A every predetermined time (for example, every minute). Thereby, position information and step count information are acquired for every progress of predetermined time. Here, as an example, the mobile terminal 102A accumulates the position information and the step count information for 10 times, but the number of times of accumulation is not limited to 10 times. As described with reference to FIG. 11, the monitoring apparatus 101A calculates the movement distance and movement speed of the user using the position information and the step count information accumulated a plurality of times.

  In step S306A, the mobile terminal 102A notifies the monitoring apparatus 101A of the accumulated position information and step count information via the wireless communication unit 102b. Note that the mobile terminal 102A notifies the monitoring apparatus 101A of the position information and the step count information accumulated 10 times, thereby reducing the number of communication between the mobile terminal 102A and the monitoring apparatus 101A, and the battery 102c of the mobile terminal 102A. The decrease in charging capacity can be suppressed.

  FIG. 11 shows an example of a process of monitoring the charge capacity of the battery 102c of the mobile terminal 102A activated by the process of step S204 executed by the monitoring apparatus 101A shown in FIG. The monitoring apparatus 101A executes step S508A instead of step S508 shown in FIG. Processing excluding step S508A is the same as that in FIG. Detailed description of the same processing as in FIG. 6 is omitted.

  In step S508A, the control unit 101a in the monitoring apparatus 101A calculates the distance traveled by the user per unit time based on the position information of the mobile terminal 102A stored in the storage unit 101d. For example, the control unit 101a reads position information for 10 consecutive times received from the mobile terminal 102A from the storage unit 101d based on the process of step S306A illustrated in FIG. 10, and sets the distance traveled by the user every 10 minutes. To calculate.

  In addition, the control unit 101a in the monitoring apparatus 101A moves the user per unit time based on the user's step information stored in the storage unit 101d and the user's step count information stored in the storage unit 101d. Calculate the distance. For example, the control unit 101a reads from the storage unit 101d the step information of the user and the 10-step continuous step number information received from the mobile terminal 102A based on the process of step S306A illustrated in FIG. Then, for example, the control unit 101a multiplies the read step length information of the user and the step number information of the user 10 times, and calculates the distance traveled by the user every 10 minutes.

  If the control unit 101a determines that the distance calculated based on the position information differs by a predetermined distance or more per unit time from the distance calculated based on the number of steps information and the step information, the distance calculated based on the position information Is corrected using the distance calculated based on the step count information and the stride information. For example, the control unit 101a may determine that the distance calculated based on the position information is different by 100 meters or more per 10 minutes from the distance calculated based on the step count information and the step length information. In this case, the control unit 101a corrects the distance calculated based on the position information with the distance calculated based on the step count information and the stride information. Then, the control unit 101a uses the corrected distance as the distance moved by the user, and obtains the moving speed of the user based on the corrected distance.

  On the other hand, if the control unit 101a determines that the distance calculated based on the position information does not differ by a predetermined distance or more per unit time from the distance calculated based on the number-of-steps information and the step length information, based on the position information The calculated distance need not be corrected. For example, if the control unit 101a determines that the distance calculated based on the position information does not differ by more than 100 meters per 10 minutes from the distance calculated based on the step count information and the step length information, the control unit 101a calculates based on the position information. The corrected distance may be the distance moved by the user without correction. Then, the control unit 101a may obtain the moving speed of the user based on the distance calculated based on the position information.

  Note that the control unit 101a uses the distance calculated based on the position information as the step count information regardless of the difference between the distance calculated based on the position information and the distance calculated based on the step count information and the step length information. You may correct | amend by the distance calculated based on step length information. The control unit 101a sets the corrected distance as the distance traveled by the user regardless of the difference between the distance calculated based on the position information and the distance calculated based on the step count information and the stride information. The moving speed of the user may be obtained based on the corrected distance.

  Further, the control unit 101a corrects the moving speed of the user obtained based on the position information by using the moving speed of the user obtained based on the number of steps information and the stride information, thereby moving the moving speed of the user. You may ask for.

  The monitoring apparatus 101A uses the step information and step count information of the user in addition to the position information, so that when the signal from the GPS satellite is interrupted, for example, when the user is in an underground shopping center, the monitoring apparatus 101A is shown in FIG. Therefore, it is possible to calculate the movement distance and movement speed of the user more accurately than the monitoring apparatus 101.

  In this embodiment as well, as in the embodiment shown in FIGS. 1 to 7, the monitoring apparatus 101A uses the geographic information system (GIS) to detect the location information and the geographic location information of the mobile terminal 102. And the moving speed of the user may be obtained.

  As described above, in this embodiment as well, as in the embodiment shown in FIGS. 1 to 7, it is possible to suppress the remaining charge capacity of the battery 102c of the mobile terminal 102 from being lost even when the user goes out. In addition, the user can charge the battery 102c before going out before the remaining charge capacity of the battery 102c of the mobile terminal 102 runs out. In addition, the possibility of the remaining charge capacity remaining due to the deterioration of the battery 102c can be reduced compared to the conventional case.

  Furthermore, in this embodiment, the monitoring apparatus 101A uses the user's stride information and step count information in addition to the position information, so that when the signal from the GPS satellite is interrupted, the monitoring apparatus shown in FIG. It is possible to calculate the moving distance and moving speed of the user more accurately than 101.

  FIG. 12 shows an example of the operation of the mobile terminal 102 in another embodiment of the monitoring device, the monitoring system, and the monitoring method. The same configurations and processes as those shown in FIGS. 1 to 7 are denoted by the same reference numerals as in FIGS. 1 to 7, and detailed description thereof is omitted. In this embodiment, as will be described with reference to FIG. 12, the monitoring apparatus 101 detects the deterioration of the battery 102c using different criteria depending on the usage status of the mobile terminal 102.

  In FIG. 12, the determination of step S315 shown in FIG. 4 is deleted, steps S316A and S316B are inserted instead of step S316 shown in FIG. 4, and step S317A is inserted instead of step S317 shown in FIG. The The processing excluding steps S316A, S316B, and 317A is the same as that in FIG. 4 except that step S315 is deleted.

  In step S316A, the mobile terminal 102 obtains the remaining charge capacity of the battery 102c together with the usage status of the mobile terminal 102 twice. For example, the usage status is determined according to the usage rate of the processor 102a. That is, the mobile terminal 102 acquires the usage rate of the processor 102a as the usage status.

  In this embodiment, the mobile terminal 102 acquires either a standby state or an operation state in which the user is operating the mobile terminal 102 as a usage state. For example, the standby state is determined when the usage rate of the processor 102a illustrated in FIG. 1 is 10% or less, and the operation state is determined when the usage rate of the processor 102a is higher than 10%.

  Next, in step S316B, the mobile terminal 102 determines whether or not the remaining charge capacity has been acquired twice under the same use situation. If the remaining charge capacity is acquired twice under the same usage conditions, the process proceeds to step S317A. For example, when the remaining charge capacity is acquired twice under the standby state, or when the remaining charge capacity is acquired twice under the operation state, the process proceeds to step S317A. .

  On the other hand, when the remaining charge capacity is acquired twice under different usage conditions, the process proceeds to step S309. For example, when the remaining charge capacity is acquired under the standby state and the operation state, the process proceeds to step S309.

  In step S317A, the mobile terminal 102 notifies the monitoring apparatus 101 of information indicating the amount of change in the remaining charge capacity of the battery 102c acquired twice together with information indicating the usage status via the wireless communication unit 102b. The monitoring apparatus 101 determines the degree of deterioration of the battery 102 c based on the notification from the mobile terminal 102. Note that the processing of steps S316A, S316B, and S317A may be performed every two days or every three days.

  FIG. 13 shows an example of the operation of the monitoring apparatus 101 that receives information notified by the mobile terminal 102 in step S317A shown in FIG. In FIG. 12, step S504A is inserted instead of step S504 shown in FIG. Processing excluding step S504 is the same as that in FIG.

  In step S <b> 504 </ b> A, the monitoring apparatus 101 uses the threshold value that differs depending on the usage status of the mobile terminal 102 based on the information indicating the amount of change in the remaining charge capacity of the battery 102 c received from the mobile terminal 102. Determine deterioration. When the control unit 101a detects the deterioration of the battery 102c, the control unit 101a proceeds to step S514. On the other hand, if the battery 102c has not deteriorated, the control unit 101a moves the process to step S505. The threshold for determining the deterioration of the battery 102 will be described with reference to FIG.

  FIG. 14 shows a method in which the monitoring apparatus 101 detects the deterioration of the battery 102c in step S504A shown in FIG. Characteristics E1, E2, and E3 in FIG. 14A indicate changes in the charging capacity of the battery 102c when the mobile terminal 102 is in the standby state, as in FIG. Characteristics E1, E2, and E3 in FIG. 14B indicate changes in the charging capacity of the battery 102c in the operation state of the mobile terminal 102 (for example, when the usage rate of the processor 102a is 70%). The characteristic E1-E3 in FIG. 14B has a larger slope than the characteristic E1-E3 in FIG. For this reason, when the mobile terminal 102 is operated, the change rate of the charge capacity is higher than the change speed of the charge capacity in the standby state. The characteristics E1, E2, and E3 in FIG. 14A are the same as the characteristics E1, E2, and E3 in FIG. 7, and the characteristics E1, E2, and E3 in FIG. Except for this, it is the same as the characteristics E1, E2, and E3 in FIG.

  In step S <b> 504 </ b> A, the monitoring apparatus 101 changes the determination criterion according to the usage status of the mobile terminal 102 received from the mobile terminal 102. That is, when the mobile terminal 102 is in the standby state, the slope indicating the rate of decrease in the charge capacity of the battery 102c is greater than the slope of the characteristic E3 (b) using the discharge characteristics of the battery 102 shown in FIG. It is determined that the battery 102c has deteriorated.

  On the other hand, when the mobile terminal 102 is in the operating state, using the discharge characteristics of the battery shown in FIG. 14B, when the slope indicating the rate of decrease in the charge capacity of the battery 102c is greater than the slope of the characteristic E3 (d), It is determined that the battery 102c has deteriorated. In FIG. 14, the discharge characteristics in the operation state of the portable terminal 102 indicate one type of FIG. 14B (for example, when the usage rate of the processor 102 a is 70%). However, the deterioration of the battery 102c may be determined by selecting one of a plurality of discharge characteristics according to the usage rate of the processor 102a of the mobile terminal 102. For example, the usage rate of the processor 102a is acquired separately for each of four types of 11% -30%, 31% -50%, 51% -70%, 71% or more, and the usage rate is 30%, 50%, 70 The deterioration of the battery 102c may be determined using the discharge characteristics in the case of% and 100%, respectively. Note that the threshold corresponding to the usage rate of the processor 102a is stored in the storage unit 101d, for example.

  As described above, the monitoring apparatus 101 detects the deterioration of the battery 102c in accordance with the usage state of the mobile terminal 102 by changing the threshold value, which is the determination condition for the deterioration of the battery 102c, according to the usage state of the mobile terminal 102. It becomes possible to do.

  In this embodiment, as in the embodiment shown in FIGS. 8 to 11, the monitoring apparatus 101 uses the user's step information and step count information in addition to the position information based on the signal from the GPS satellite. Thus, the moving speed of the user may be obtained.

  As described above, in this embodiment as well, as in the embodiment shown in FIGS. 1 to 7, it is possible to suppress the remaining charge capacity of the battery 102c of the mobile terminal 102 from being lost even when the user goes out. In addition, the user can charge the battery 102c before going out before the remaining charge capacity of the battery 102c of the mobile terminal 102 runs out. In addition, the possibility of the remaining charge capacity remaining due to the deterioration of the battery 102c can be reduced compared to the conventional case.

  Furthermore, in this embodiment, the monitoring apparatus 101 changes the deterioration of the battery 102c according to the usage status of the mobile terminal 102 by changing the threshold value, which is the determination condition for the deterioration of the battery 102c, according to the usage status of the mobile terminal 102. Can be detected.
