  When the input value from the logic circuit 591 is Low, the switching circuit 595 supplies power from the battery 195 to the power supply circuit unit 198 and charges the battery 195. In addition, when the input value from the logic circuit 591 is High, supply of power from the battery 195 to the power supply circuit unit 198 and charging of the battery 195 are stopped.

  The switching circuit (590, 595) is a circuit for controlling ON / OFF of the battery 190 and the emergency battery 195, and when one of them is Low, the other is High.

  Next, a specific operation of the mobile phone with a GPS function according to the present embodiment will be described with reference to FIGS.

  First, the user of the mobile phone with GPS function operates the operation unit 100 to e-mail the time for starting up the mobile phone at a fixed time interval and the positioning result indicating the current location acquired using the GPS function after starting up. The emergency contact information to be transmitted is set in the table 115 (shown in Table 1) (step S301). It should be noted that the following operations are not executed when the time interval for activating the mobile phone and the emergency contact information are not set.

  The voltage detector 191 always monitors the battery level of the battery 190, and determines whether or not the battery level of the battery 190 is lower than the threshold value of the battery 190 set in the table 116 (shown in Table 2) (step S302). ). When the battery level of the battery 190 is lower than the threshold value of the battery 190 set in the table 116 (step S302 / YES), specifically, when the battery 190 is detached from the mobile phone, or the battery capacity of the battery 190 Decreases and the battery level higher than the threshold value cannot be maintained, the logic circuit 591 outputs a signal (Low) for switching the power supply source from the battery 190 to the emergency battery 195 (step S303).

  When Low is output from the logic circuit 591, Low is input to the switching circuit 595 and power is supplied from the emergency battery 195 to the power supply circuit unit 198. At the same time, Low from the logic circuit 591 is inverted in the inverting circuit 592, and High is input to the switching circuit 590, and supply of power from the battery 190 to the power supply circuit unit 198 is stopped. Note that while power is being supplied from the emergency battery 195 to the power supply circuit unit 198, the control unit 120 does not accept activation of the power supply by a user operation.

  When the supply of power from the emergency battery 195 to the power supply circuit unit 198 is started, the control unit 120 starts a power supply start timer (not shown), and the start interval (for example, 1 hour) set in the table 115 shown in Table 1 ) Is determined (step S304).

  When one hour has elapsed since the start of the power activation timer (step S304 / YES), the control unit 120 activates the power supply of the mobile phone (step S305). However, even if the power source of the mobile phone is activated in step S305, the control unit 120 operates each unit so that the power source is not activated apparently until the positioning result mail transmission in step S307 is completed. By operating each part so that the power supply is not activated in appearance, for example, the criminal who kidnapped the child cannot recognize the current location notification even when looking at the mobile phone, and the child's whereabouts are not known to the criminal Can be specified.

  Further, the control unit 120 operates so that the power supply is not activated while the cellular phone is activated by power supply from the emergency battery 195 to the power supply circuit unit 198, and at the same time, the GPS function and the mail function The use of other functions is restricted, and the consumption of excess power of the emergency battery 195 is reduced. It should be noted that while the power supply from the emergency battery 195 is being performed, which function is restricted from being used may be set in advance, or may be configured arbitrarily by the user.

  When the power of the mobile phone is activated in step S305, the control unit 120 performs positioning of the current location of the own device using the GPS module 180 (step S306). When positioning of the current location is executed by the GPS module 180 and the positioning result is acquired, the control unit 120 transmits the acquired positioning result to an emergency contact address preset in the table 115 by mail (step S307).

  In addition, as shown in FIG. 4A, the emergency contact terminal has a message such as “Emergency contact! Mr. A's power has been turned off. Location information will be notified every hour.” , And a positioning result by the GPS module 180 is transmitted. Here, the URL of the map representing the positioning result such as “http: //navi.xxxx” is transmitted as the positioning result, and the emergency contact terminal accesses this URL to determine the current location of the mobile phone from which the mail is sent. It can be known (shown in FIG. 4B).

  When the positioning result mail transmission is completed, the control unit 120 determines whether or not the battery level of the battery 190 by the voltage detector 191 is lower than the threshold value of the battery 190 set in the table 116 (step S308).

  When the battery level of the battery 190 is equal to or higher than the threshold value of the battery 190 set in the table 116 (step S308 / YES), the logic circuit 591 outputs a signal (High) for switching the power supply source from the emergency battery 195 to the battery 190. ) Is output.

  When High is output from the logic circuit 591, High is input to the switching circuit 595 and power supply from the emergency battery 195 to the power supply circuit unit 198 is stopped. At the same time, High from the logic circuit 591 is inverted in the inverting circuit 592, and Low is input to the switching circuit 590, so that power supply from the battery 190 to the power supply circuit unit 198 is started. When the supply of electric power from the battery 195 to the power supply circuit unit 198 is started, the control unit 120 accepts activation of the power supply by a user operation.

  On the other hand, when the battery level of the battery 190 is lower than the threshold value of the battery 190 set in the table 116 (step S308 / NO), the control unit 120 turns off the power of the mobile phone (step S309) and sets the power activation timer again. It is started, and it is determined whether or not the activation interval set in the table 115 has elapsed (step S304). In step S309, the power of the emergency battery 195 can be extended for a long time by temporarily turning off the power of the mobile phone.

  Next, the operation of charging the battery 190 and the emergency battery 195 will be described with reference to FIG.

  Charger 500 is connected to connector 199 of the mobile phone. When detecting the connection of the charger 500 to the connector 199, the control unit 120 first detects the current voltage value of the emergency battery 195 via the charging circuit unit 197 and fills the emergency battery 195 stored in the table 116. Compare with charge value (for example, 4V). Note that when the battery level of the current emergency battery 195 is less than the full charge value, the control unit 120 outputs Low. Further, when the battery level of the emergency battery 195 is less than the full charge value, the battery 190 is detached from the mobile phone, or the battery capacity of the battery 190 is decreased, so that the battery level above the threshold cannot be maintained. Therefore, Low is also output from the voltage detector 191. Therefore, the logic circuit 591 outputs Low, activates the switching circuit 595, and starts charging the emergency battery 195.

  When charging to the emergency battery 195 is completed, High is output from the control unit, and the logic circuit 591 also outputs High to activate the switching circuit 590 and start charging the battery 190. Specifically, the control unit 120 reads the voltage value of the emergency battery 195 via the charging circuit unit 197, confirms that the battery level of the emergency battery 195 has reached the full charge value, and outputs High to the logic circuit 591. To do. Since High is output from the logic circuit 591, the switching circuit 595 is stopped, the switching circuit 590 is activated, and charging of the battery 190 is started.

  According to the above configuration, even when the battery is removed for some reason or the battery capacity is exhausted, the GPS function can be measured by the emergency battery built into the mobile phone and the location of the mobile phone can be notified. Therefore, it can be used for crime prevention.

  Next, the configuration and operation of a mobile phone with a GPS function according to another embodiment will be described. The configuration of the mobile phone with GPS function according to the present embodiment is the same as the configuration of the mobile phone with GPS function according to the above-described embodiment shown in FIGS. 1 and 5 except for the settings stored in the table 115. Therefore, the description is omitted here.

  First, information set in the table 115 will be described. As shown in Table 3, the table 115 according to the present embodiment includes time information for turning on its own device at regular intervals, an emergency contact for transmitting a positioning result by the GPS function, a standby time for maintaining a standby state, and Holds the waiting time until the power is turned off again.

  Next, the operation of the mobile phone with a GPS function according to the present embodiment will be described with reference to FIGS. In the present embodiment, a mobile phone that is out of battery or has no battery capacity and is not turned on is periodically activated to enter a standby state to make a call or mail, and again after a certain period of time. It is characterized by a power failure.

  First, the user of the mobile phone with a GPS function transmits a positioning result indicating the current location obtained by using the GPS function after starting for a time for operating the operation unit 100 to start the own device at regular time intervals. The emergency contact to be performed, the standby time for maintaining the standby state, and the standby time until the power is turned off again are set in the table 115 (shown in Table 3) (step S601). It should be noted that the following operations are not executed when the time interval for activating the mobile phone, the emergency contact information, the standby time, and the standby time are not set.

  The voltage detector 191 always monitors the battery level of the battery 190 and determines whether or not the battery level of the battery 190 is lower than the threshold value of the battery 190 set in the table 116 (shown in Table 2) (step S602). ). When the battery level of the battery 190 is lower than the threshold value of the battery 190 set in the table 116 (step S602 / YES), specifically, when the battery 190 is removed from the mobile phone, or the battery capacity of the battery 190 Decreases and the battery level higher than the threshold value cannot be maintained, the logic circuit 591 outputs a signal (Low) for switching the power supply source from the battery 190 to the emergency battery 195 (step S603).

  When Low is output from the logic circuit 591, Low is input to the switching circuit 595 and power is supplied from the emergency battery 195 to the power supply circuit unit 198. At the same time, Low from the logic circuit 591 is inverted in the inverting circuit 592, and High is input to the switching circuit 590, and supply of power from the battery 190 to the power supply circuit unit 198 is stopped. Note that while power is being supplied from the emergency battery 195 to the power supply circuit unit 198, the control unit 120 does not accept activation of the power supply by a user operation.

  When supply of power from the emergency battery 195 to the power supply circuit 198 is started, the control unit 120 sends an “Emergency contact! Mr. A power supply” to the emergency contact terminal set in the table 115 as shown in FIG. Is turned off. It waits only for 5 minutes every hour. " Note that the control unit 120 reads the activation interval and standby time set in the table 115, and transmits mail based on the information.

  When the supply of power from the emergency battery 195 to the power supply circuit unit 198 is started, the control unit 120 starts a power supply start timer (not shown), and the start interval (for example, 1 hour) set in the table 115 shown in Table 3 ) Is determined (step S605).

  When one hour has elapsed since the start of the power activation timer (step S605 / YES), the control unit 120 activates the power supply of the mobile phone (step S606).

  When the power of the mobile phone is activated, the control unit 120 starts a standby timer (not shown), and determines whether or not a standby time (for example, 5 minutes) set in the table 115 has elapsed (step S607). ). During the standby time, the mobile phone can perform communications such as calls and emails. For example, there is a reply from the mail transmission destination notified in step S604, or communication can be performed to an arbitrary destination. Note that the control unit 120 does not forcibly terminate the communication halfway even when the standby time has elapsed during communication, and checks whether the standby time has elapsed again after the communication ends (step S607). .

  Further, the control unit 120 restricts the use of functions other than the GPS function, the mail function, and the call function while the mobile phone is activated by supplying power from the emergency battery 195 to the power supply circuit unit 198. Reduce the consumption of 195 extra power. It should be noted that while the power supply from the emergency battery 195 is being performed, which function is restricted from being used may be set in advance, or may be configured arbitrarily by the user.

  When the standby time has elapsed (step S607 / YES), the control unit 120 determines whether or not the battery level of the battery 190 by the voltage detector 191 is lower than the threshold value of the battery 190 set in the table 116 (step S608). .

  When the battery level of the battery 190 is equal to or higher than the threshold value of the battery 190 set in the table 116 (step S608 / YES), the logic circuit 591 outputs a signal (High) for switching the power supply source from the emergency battery 195 to the battery 190. ) Is output.

  When High is output from the logic circuit 591, High is input to the switching circuit 595 and power supply from the emergency battery 195 to the power supply circuit unit 198 is stopped.
