<Embodiment 1>
FIG. 1 is a block diagram showing an overall configuration of the terminal management system 100 according to the first embodiment. The terminal management system 100 includes a terminal device 1, a management terminal 2, and a management server 3. The management terminal 2 and the management server 3 are connected to the network N. It is assumed that the terminal device 1 moves with the movement of the user who carries the terminal device 1, or can move independently. Further, the terminal device 1 can be connected to the network N by wireless communication. Therefore, when the terminal device 1 is connected to the network N, the terminal device 1 can communicate with the management terminal 2 and the management server 3 via the network N. Further, if the terminal device 1 and the management terminal 2 are in a short distance, direct communication may be possible.

In the example of FIG. 1, the terminal device 1 and the management terminal 2 are in a state of existing within the range of the first region R1. The first region R1 is, for example, a region indicating a safe area (safety area). Further, in the present embodiment, a region other than the first region R1 is referred to as a second region R2. The second region R2 is an region indicating a non-safety zone or a dangerous region. In the example of FIG. 1, the first region R1 exists inside the second region R2, but the second region R2 may exist inside the first region R1. Further, the terminal device 1 may be located in the second region R2.

The management terminal 2 is an information processing terminal operated by an administrator (such as a guardian of a user who uses the terminal device 1) for monitoring and managing the terminal device 1, and is, for example, a mobile phone, a smartphone, a tablet terminal, or a personal computer. Computers, etc. The management terminal 2 accesses the management server 3 via the network N according to the operation of the administrator, and inputs and outputs information. The management terminal 2 may be movable or may have a fixed position. In the example of FIG. 1, the management terminal 2 is located in the first area R1, but may be located in the second area R2.

The management server 3 is a server device for monitoring and managing the terminal device 1. The management server 3 receives and holds the position information transmitted from the terminal device 1. Further, the management server 3 outputs the position information of the terminal device 1 to the management terminal 2 in response to the request from the management terminal 2. Further, the management server 3 may establish a communication connection between the terminal device 1 and the management terminal 2 and relay the communication.

FIG. 2 is a block diagram showing the configuration of the terminal device 1 according to the first embodiment. The terminal device 1 is an information processing terminal capable of wireless communication and movement. The terminal device 1 is, for example, a mobile phone, a smartphone, a tablet terminal or other portable wireless terminal device carried by a user. The terminal device 1 includes a storage unit 11, a GPS (Global Positioning System) signal receiving unit 12, a control unit 13, and a communication unit 14.

The storage unit 11 is a storage device that stores the safety area definition information 111, the battery level threshold 112, the position information transmission cycle 113, the position information transmission destination 114, and the state transition control program 115 in advance. The safety area definition information 111 is information that defines a first area R1 having an area attribute that is a safety area. For example, the safety area definition information 111 is a rectangular area surrounded by latitude / longitude data of four points, or a circular area surrounded by latitude / longitude data of one point and radius r. FIG. 3 is a diagram showing an example of a safety region R1a defined by a rectangular region. Further, FIG. 4 is a diagram showing an example of a safety region R1b defined by a circular region. The safety area definition information 111 may include not only the definition of one area but also the definitions of a plurality of areas as area attributes. Further, the safety region definition information 111 includes the definition of the third region R3, which is a specific region included in the first region R1. For example, although not shown, in FIG. 3, a third region is defined inside the safety region R1a, and in FIG. 4, a third region is defined inside the safety region R1b. That is, the third region R3 is a region within the first region R1 that is defined as being more secure. The safety area definition information 111 stored in the storage unit 11 in this way is information that defines area attributes for each of the plurality of areas, and may be referred to as area definition information.

Here, it is assumed that the user specifies the safety area definition information 111 in advance. For example, the terminal device 1 to be monitored, that is, the user of the target terminal, specifies a desired area on the map displayed on the screen (not shown) of the own terminal. As a result, the storage unit 11 stores the designated area as the safety area definition information 111.

Alternatively, the user of the management terminal 2 that monitors the target terminal specifies a desired area on the map displayed on the screen (not shown) of the own terminal. As a result, the terminal device 1 receives the area designated on the management terminal 2 via the network N, and the storage unit 11 stores the received area as the safety area definition information 111.

The battery remaining amount level threshold value 112 is a threshold value relating to the remaining amount of the battery (battery remaining amount) mounted on the terminal device 1 and supplying electric power. The battery remaining amount level threshold value 112 is data indicating a threshold value of the battery remaining amount at which the operation mode of the terminal device 1 is changed, that is, the state is changed.

The position information transmission cycle 113 is data indicating a cycle in which the terminal device 1 transmits the current position information (latitude, longitude, etc.) to the destination indicated by the position information transmission destination 114 via the network N.

The location information transmission destination 114 is destination information indicating a destination of location information. For example, the location information transmission destination 114 is an IP (Internet Protocol) address of the management server 3, an e-mail address that can be received by the management server 3, an e-mail address of the management terminal 2, and the like. Alternatively, when the terminal device 1 is a commercial radio, the location information transmission destination 114 may be the terminal ID or group ID of the radio.

The state transition control program 115 is a computer program in which the state transition control process according to the present embodiment is implemented.

The GPS signal receiving unit 12 receives a GPS signal at a predetermined measurement timing, and outputs each received GPS signal to the control unit 13. The measurement timing is based on an instruction from the control unit 13 or a timer (not shown) setting described later.

The communication unit 14 is an interface circuit that performs wireless communication with the outside of the terminal device 1.

The control unit 13 is a processor, that is, a control device that controls each configuration of the terminal device 1. The control unit 13 reads the state transition control program 115 from the storage unit 11 into a memory (not shown), and executes the state transition control program 115. Further, the control unit 13 appropriately reads the safety area definition information 111, the battery remaining amount level threshold value 112, the position information transmission cycle 113, and the position information transmission destination 114 from the storage unit 11 into the memory. As a result, the control unit 13 realizes the functions of the operation mode control unit 131, the position information acquisition unit 132, the position determination unit 133, the battery remaining amount monitoring unit 134, and the position information transmission unit 135, which will be described later.

The position information acquisition unit 132 acquires position information (current position) from the GPS information received by the GPS signal reception unit 12. The position determination unit 133 determines whether the current position is inside or outside the safety area based on the acquired position information and the safety area definition information 111. That is, the position determination unit 133 determines the area including the current position and the attributes of the area. The battery remaining amount monitoring unit 134 acquires the current battery remaining amount, and determines whether or not the acquired battery remaining amount is less than the battery remaining amount level threshold value 112.

The position information transmission unit 135 transmits the position information to the position information transmission destination 114 by using the communication unit 14 in the cycle set in the position information transmission cycle 113. Here, as will be described later, the position information transmission unit 135 may adjust the transmission cycle of the position information, that is, the transmission condition, according to the remaining battery level of the terminal device 1.

The operation mode control unit 131 controls the operation mode of the terminal device 1. There are two modes of operation of the terminal device 1, "normal mode" and "emergency mode". The "normal mode" is a mode in which the terminal device 1 is located in the first area R1 (safety area). The "emergency mode" is a mode in which the terminal device 1 is located in the second area R2 (dangerous area) and the terminal device 1 satisfies a predetermined condition. The predetermined conditions will be described later. Further, the terminal device 1 takes a plurality of states according to the operation mode and the remaining battery level. FIG. 5 is a diagram showing the relationship between the state according to the first embodiment and the remaining battery level.

First, the "state A" is a state in which the power of the terminal device 1 is turned on in the "normal mode", and is also called a first state. The "state A" is a state in which the normal operation (call function, etc.) of the terminal device 1 can be performed, that is, an operation mode in which the normal function can be executed.

Next, the "state B" is a state in which the remaining battery level is equal to or higher than a predetermined level in the "emergency mode", and is also called a second state. In "state B", the terminal device 1 intermittently performs GPS positioning and intermittently transmits position information to a preset destination. Here, the reason for operating intermittently is to continue the operation for as long as possible. Therefore, in the "state B", the display and the sound may be turned off, and the power may be apparently turned off. Therefore, it can be said that the second state is a state in which the power consumption of the own terminal device is suppressed as compared with the first state, and the position information of the own terminal device is transmitted to a predetermined destination at a predetermined interval.

Further, the "state C" is a state in which the power is turned off by pressing the power button in the normal mode, and is also called a "power off 1" state. In order to return from "state C" to "state A", it is necessary to press the power button again. The "state D" is a state in which only the minimum necessary functions are operated in order to extend the operating time of the battery as much as possible when the remaining battery level is low in the normal mode, and is also called a "power OFF 2" state. It is a so-called energy-saving state.

Subsequently, the "battery remaining amount level 1" is a threshold value of the battery remaining amount which is a condition when the terminal device 1 transitions from the normal mode to the emergency mode. “Battery level 2” is the minimum battery level that can maintain the normal function of the terminal device 1. When the remaining battery level becomes less than the remaining battery level 2 in the normal mode, the state transitions to the state D, only the minimum necessary functions (for example, the function for receiving a call) are operated, and other functions (for example, extra) are operated. Display function, etc.) is stopped. “Battery level 3” is the minimum battery level required for the terminal device 1 to operate. When the remaining battery level is less than the remaining battery level 3, a so-called dead battery state is established. In either the normal mode or the emergency mode, the terminal device 1 cannot operate at all unless it is charged. Therefore, it is one of the conditions for transitioning from the state A to the state B that the remaining battery level is less than the "remaining battery level 1" (and the level 3 or higher). As will be described later, in the terminal device 1, the terminal device 1 in the normal mode (state A) moves from the first region R1 to the second region R2, and the remaining battery level is less than the remaining battery level 1 (and). When the battery level is 3 or higher), the emergency mode (state B) shall be entered. Here, it is assumed that "battery level 1"> "battery level 2"> "battery level 3". In particular, the reason why "battery level 1"> "battery level 2" is that it is necessary to lengthen the time until the battery runs out in the emergency mode as much as possible.

The operation mode control unit 131 shown in FIG. 2 includes a first transition unit 1311 and a second transition unit 1312. FIG. 6 is a diagram showing an example of a region used in the transition from the state A to the state B according to the first embodiment. The first transition unit 1311 puts the terminal device 1 which is the own terminal device into the first state (state A) by moving the terminal device 1 which is the own terminal device from the first area R1 to the second area R2. ) To the second state (state B). That is, the first transition unit 1311 transitions the state of the terminal device 1 from the first state to the second state when a predetermined condition is satisfied.

Further, FIG. 7 is a diagram showing an example of a region used in the transition from the state B to the state A according to the first embodiment. The second transition unit 1312 is a second when the terminal device 1 moves from the second region R2 to the third region R3 included in the first region R1 after the transition by the first transition unit 1311. The transition from the state (state B) to the first state (state A). That is, the second transition unit 1312 transitions the state of the terminal device 1 from the second state to the first state when a predetermined condition is satisfied in the second state. For example, when the second region R2 is a dangerous region, it is not restored by simply returning from the second region R2 to the first region R1, but a specific region within the first region R1. It returns to the first state only after moving to the area R3 of 3. Therefore, the danger due to the existing position of the terminal device 1 is taken into consideration, and the safety of the user of the terminal device can be improved. In particular, when the first region R1 and the second region R2 are adjacent to each other, the third region R3 is a predetermined distance d from the boundary between the first region R1 and the second region R2. It is desirable to isolate the above.

Subsequently, the state transition in the present embodiment will be described in detail. FIG. 8 is a diagram summarizing the conditions and the transition destination in the transition from the state A according to the first embodiment.

<When the terminal device 1 is in the state A and exists in the safe area>
When the terminal device 1 is in the safe area, it operates in the normal mode in principle. When the power OFF operation is performed in the normal mode (power ON) (state A), the terminal device 1 transitions to the normal mode (power OFF 1) (state C) regardless of the remaining battery level. Further, in the normal mode (power ON) (state A), the terminal device 1 transitions to the normal mode (power OFF 2) (state D) when the remaining battery level becomes less than level 2. Further, the terminal device 1 transitions to the normal mode (power ON) (state A) when the power ON operation is performed in the normal mode (power OFF 1) (state C).

<When the terminal device 1 is in the state A and moves out of the safe area>
The first transition unit 1311 transitions from the first state to the second state when the own terminal device moves from the first region R1 to the second region R2 and satisfies a predetermined condition. Here, the predetermined conditions are that the remaining battery level of the own terminal device is less than a predetermined level (for example, level 1), the power off operation for the own terminal device is detected, and the battery of the own terminal device. At least one of the cases when a sign that the battery is removed is detected. Moreover, you may combine these conditions.

The terminal device 1 transitions from the normal mode to the emergency mode when at least one of the following three conditions is satisfied.

(Condition 1) When the remaining battery level is less than level 1 (however, level 3 or higher) In this case, it is apparently desirable to turn off the power. That is, the display of the display unit of the terminal device 1 disappears, and even if the operation unit is operated, the terminal device 1 does not respond.
(Condition 2) When the power off operation is performed In this case, the power is apparently turned off 1.
(Condition 3) When the operation of opening the lid of the battery case is detected The operation of opening the lid of the battery case may be detected by using a known technique including, for example, an optical sensor or a microswitch. Here, the "operation of opening the lid of the battery case" can be said to be a sign that the battery of the terminal device 1 is removed. In this case, the power may be turned off 1 in appearance. Alternatively, an audible alarm may be sounded. In addition, the structure is such that the lid of the battery case cannot be easily opened, and the time from when the operation to open the lid (such as loosening the screw) to the removal of the battery is secured so that the location information can be transmitted. You may try to do it.

Alternatively, the terminal device 1 may request the user's biometric authentication (fingerprint authentication, iris authentication, face authentication, voiceprint authentication, etc.) when the power is turned off or the battery case lid is removed. .. Further, when biometric authentication is performed in the emergency mode, the terminal device 1 may transmit data related to biometric authentication to the management server 3 regardless of the authentication result. In this case, the management server 3 may collect data related to biometric authentication, which may lead to identification of a third party who is not a legitimate user.

Further, in the emergency mode, the terminal device 1 does not accept a normal operation from the operation unit. That is, it is assumed that the terminal device 1 does not respond even if a normal operation is performed. Here, in the emergency mode, the reason for turning off all the displays and not accepting normal operations is to preserve the remaining battery power as much as possible. It is also intended that a third party may mistake the terminal for a dead battery.

The operation of the emergency mode may be changed according to the factor of shifting to the emergency mode and the remaining battery level.

(1) The frequency of transmitting location information may be changed according to the remaining battery level. Specifically, the control unit 13 lengthens the position information transmission cycle 113 as the remaining battery power decreases. For example, when the remaining battery level is 50%, the control unit 13 sets the position information transmission cycle 113 at 30-second intervals, and when the remaining battery level is 20%, sets the position information transmission cycle 113 at 5-minute intervals, and the remaining battery level is 10. When%, the position information transmission cycle 113 is set at 10-minute intervals.

(2) The type of data to be transmitted may be changed according to the remaining battery level. For example, when the battery level is high, the control unit 13 picks up the sound taken by the camera of the terminal device 1 (not shown) or the microphone of the terminal device 1 (not shown) in addition to the position information. Sound may be transmitted. On the other hand, when the battery is low, the control unit 13 transmits only the position information by the position information transmission unit 135.

(3) The transmission power may be changed according to the remaining battery level. For example, when the battery level is high, the control unit 13 may increase the transmission power to transmit the position information or the like so that the radio waves can reach the base station or the management terminal reliably.

(4) When the power is turned off and the emergency mode is entered, that is, when the state B is entered according to the above "condition 2", the remaining battery level at that time is level 1 or higher. Therefore, when the mode is changed to the emergency mode according to "Condition 2", there is a margin in the remaining battery power as compared with the case where the mode is changed to the emergency mode according to "Condition 1". Therefore, the position information transmission interval and the type of data to be transmitted , Transmission power, etc. may be changed. That is, when the emergency mode is entered according to "Condition 2", the control unit 13 shortens the position information transmission interval (position information transmission cycle 113) or shortens the position information transmission interval (position information transmission cycle 113) as compared with the case where the transition is made under "Condition 1". Image data and audio data may also be transmitted, or processing such as increasing the transmission power may be performed.

(5) When the emergency mode is entered according to the above "condition 3", it is assumed that the operating time is extremely short. Therefore, it should be prioritized to transmit as much information as possible in a short time rather than preserving the battery. Is. Therefore, in the case of "Condition 3", the control unit 13 may change the transmission interval of the position information, the type of data to be transmitted, the transmission power, and the like. That is, when the emergency mode is entered according to the "condition 3", the control unit 13 has a position information transmission interval (position information transmission cycle 113) as compared with the case where the transition is made under the "condition 1" and the "condition 2". May be shorter, or the transmission power may be larger. Further, the control unit 13 may transmit video (moving) data with audio instead of image data. That is, more types of data may be transmitted so that the surrounding situation of the terminal device 1 can be understood in more detail and it is easy to identify a third party.

<When the terminal device 1 is in the state B and exists in the safe area>
FIG. 9 is a diagram summarizing the conditions and the transition destination in the transition from the state B according to the first embodiment. As described above, in the second transition unit 1312, when the terminal device 1 moves from the second region R2 to the third region R3 included in the first region R1 after the transition by the first transition unit 1311. , The emergency mode of the terminal device 1 is canceled and the mode is changed to the normal mode. If the remaining battery level is level 2 or higher, the transition from the second state (state B) to the first state (state A) occurs. If the remaining battery level is less than level 2 and level 3 or higher, the state D is entered.

Here, it is assumed that the third region R3 is, for example, separated from the boundary between the first region R1 and the second region R2 by a predetermined distance d or more. Alternatively, the third area R3 may be within the first area R1 and within a predetermined distance from the management terminal 2, for example, within 10 m.

As will be described later, the emergency mode may be canceled when a predetermined condition is satisfied outside the safe area. In that case, the predetermined time (for example, 1 hour) may be controlled so as not to shift to the emergency mode again. That is, the first transition unit 1311 may suppress the transition to the second state again until a predetermined time elapses after the transition by the second transition unit 1312. As a result, when the terminal device 1 is moving near the boundary between the first region R1 and the second region R2, it is possible to prevent the operation from becoming unstable due to repeated state transitions.

Further, the predetermined time may be adjusted according to the moving direction of the terminal device 1 after the emergency mode is released. That is, the first transition unit 1311 may adjust the predetermined time according to the moving direction of the terminal device 1 after the transition from the second state to the first state. For example, when the terminal device 1 is moving in the direction of the safe area (such as the direction of the center of the safe area), a predetermined time is set longer, and the terminal device 1 is moving in the direction away from the safe area. The predetermined time may be shortened.

Further, when the terminal device 1 after the emergency mode is released is moving in the direction of the management terminal 2, the predetermined time is lengthened, and when the terminal device 1 is moving in the direction away from the management terminal 2, the predetermined time is set. May be shortened.

<State transition processing>
FIG. 10 is a flowchart showing the flow of the state transition process (mainly the normal mode) according to the first embodiment. First, the operation mode control unit 131 determines whether or not the current operation mode of the terminal device 1 is the normal mode power ON state (S101). If it is determined that the normal mode power is not on, the process proceeds to B in FIG. 11 to be described later. On the other hand, when it is determined that the normal mode power is ON, the GPS signal receiving unit 12 receives the GPS signal (S102). Then, the position information acquisition unit 132 acquires position information indicating the latitude and longitude which are the current positions of the terminal device 1 based on the GPS signal received in step S102 (S103).

Subsequently, the position determination unit 133 determines whether or not the terminal device 1 exists in the safe area (S104). That is, the position determination unit 133 determines whether or not the position information acquired in step S103 is within the safety area defined in the safety area definition information 111.

When it is determined in step S104 that the terminal device 1 exists in the safe area, the battery level monitoring unit 134 determines whether or not the current battery level of the terminal device 1 is less than level 2 (S105).

When it is determined in step S105 that the remaining battery level is less than level 2, the operation mode control unit 131 shifts to the normal mode power OFF 2 state (state D) (S106). If it is determined in step S105 that the remaining battery level is level 2 or higher, the process returns to step S101.

When it is determined in step S104 that the terminal device 1 does not exist in the safe area, the battery level monitoring unit 134 determines whether or not the current battery level of the terminal device 1 is less than level 1 (S107). ..

When it is determined in step S107 that the remaining battery level is less than level 1, the operation mode control unit 131 shifts to the emergency mode (S108). After that, the process returns to step S101.

If it is determined in step S107 that the remaining battery level is level 1 or higher, the process returns to step S101.

FIG. 11 is a flowchart showing the flow of the state transition process (mainly the emergency mode) according to the first embodiment. First, in step S101 of FIG. 10, when it is determined that the normal mode power supply is not ON, the operation mode control unit 131 determines whether or not the current operation mode of the terminal device 1 is the emergency mode (S111). ). If it is determined that the mode is not in emergency mode, the process returns to A in FIG. On the other hand, when it is determined that the mode is an emergency mode, the control unit 13 turns off the display on the display unit of the terminal device 1 and turns off the input / output of the voice (S112). As a result, power consumption can be suppressed and battery exhaustion can be postponed.

Next, the GPS signal receiving unit 12 receives the GPS signal (S113). Then, the position information acquisition unit 132 acquires position information indicating the latitude and longitude which are the current positions of the terminal device 1 based on the GPS signal received in step S113 (S114). Then, the position information transmission unit 135 transmits the acquired position information to the destination indicated by the position information transmission destination 114 by using the communication unit 14 (S115).

If the remaining battery level is less than the predetermined value, the GPS signal reception process (S113) and the position information acquisition process (S114) may be omitted. By omitting these processes, the battery exhaustion can be postponed. Then, in this case, in step S115, the position information transmission unit 135 transmits the position information indicating the past position a little earlier. This position information is not the position information indicating the latest position of the terminal device 1, but it is the position information a little before, so it can be said that it is useful for activities such as rescue.

<Return process>
Subsequently, the control unit 13 attempts a return process (S116). FIG. 12 is a flowchart showing the flow of the state transition process (details of the return process shown in S116) according to the first embodiment. First, the position determination unit 133 determines whether or not the terminal device 1 exists in the third region R3 (S121). That is, the position determination unit 133 determines whether or not the position information acquired in step S114 is within the third region R3 defined in the safety area definition information 111.

When it is determined in step S121 that the terminal device 1 exists in the third region R3, the battery level monitoring unit 134 determines whether or not the current battery level of the terminal device 1 is less than level 2 ( S122).

When it is determined in step S122 that the remaining battery level is less than level 2, the operation mode control unit 131 shifts to the normal mode power OFF 2 state (S123). When it is determined in step S122 that the remaining battery level is level 2 or higher, the operation mode control unit 131 shifts to the normal mode power ON state (S124). After step S123 or S124, the process returns to A in FIG.

If it is determined in step S121 that the terminal device 1 does not exist in the third region R3, the process proceeds to step S117 in FIG.

The control unit 13 sets a periodic timer (not shown) so that an interrupt is generated after a predetermined time has elapsed (S117). The control unit 13 may set the predetermined time according to the remaining battery level. For example, the control unit 13 may set a predetermined time longer as the remaining battery power decreases. By such a process, when the remaining battery power is low, the transmission interval of the position information becomes long, so that the battery exhaustion can be postponed.

Then, the control unit 13 determines whether or not the predetermined time has elapsed (S118). If it is determined that the predetermined time has elapsed, the process returns to step S113.

<Power off processing>
FIG. 13 is a flowchart showing the flow of the power-off process according to the first embodiment. When the control unit 13 detects a power-off operation for the terminal device 1, the control unit 13 executes the power-off process by an interrupt.

First, the GPS signal receiving unit 12 receives the GPS signal (S131). Then, the position information acquisition unit 132 acquires position information indicating the latitude and longitude which are the current positions of the terminal device 1 based on the GPS signal received in step S131 (S132).

Subsequently, the position determination unit 133 determines whether or not the terminal device 1 exists in the safe area (S133). When it is determined in step S133 that the terminal device 1 exists in the safe area, the operation mode control unit 131 shifts to the power OFF1 state of the normal mode (S134). When it is determined in step S133 that the terminal device 1 does not exist in the safe area, the operation mode control unit 131 shifts to the emergency mode (S135). After step S134 or S135, the process returns to A in FIG.

When the terminal device 1 detects an operation of opening the lid of the battery case, the terminal device 1 executes the same process as the power-off process. That is, when it is determined in step S133 that the terminal device 1 does not exist in the safe area, the operation mode control unit 131 shifts to the emergency mode in step S135.

In the above description, the same battery (battery) is used in the normal mode and the emergency mode, but the batteries used in the two modes may be different. In other words, prepare a battery for emergency mode, and do not use this battery in normal mode. Further, when the battery for the emergency mode is not remaining and the battery for the normal mode is remaining, the battery for the normal mode may be used in the emergency mode.

Here, one aspect of the effect of the present embodiment will be described. First, the danger of the user of the portable wireless terminal device also depends on the place where the user who owns the portable wireless terminal device exists. Therefore, when the terminal device goes out of the safe area, it is desirable to shift to the emergency mode regardless of the operation.

However, in Patent Document 1 described above, it is necessary to transition to the alert mode in advance in order to transition to the emergency mode. Then, in Patent Document 1, in order to transition from the normal mode to the alert mode, it is necessary to perform a predetermined key operation or set a schedule, which is complicated. In particular, the predetermined "key operation" may be forgotten when the user is a child or an elderly person. In addition, it is difficult to properly set the "schedule setting" when it is not clear in advance the date and time when caution is required. Therefore, in Patent Document 1, there is a possibility that the effect of the emergency mode cannot be sufficiently exhibited.

On the other hand, in the present embodiment, the normal mode can be directly changed to the emergency mode depending on predetermined conditions such as the position of the terminal device and the remaining battery level. Therefore, the operation is not complicated and the safety is high.

Further, in the present embodiment, the location of the terminal can be known even when the power of the terminal is turned off by a third party or the possibility that the battery is removed is high. Therefore, it is useful for dealing with crime damage such as kidnapping of children and the elderly. It is also useful for mountain accident relief.

In addition, since it is not necessary to shift to the alert mode by key operation or schedule setting in advance, it is possible to avoid the risk that the emergency mode will not be activated due to an operation error or setting omission. Therefore, the above effect can be fully exerted.

<Modification example>
In addition, the following modified examples can also be adopted in this embodiment. Instead of storing the safety area definition information 111 in the storage unit 11 of the terminal device 1, the danger area definition information indicating the danger area may be stored. Here, the danger area definition information is composed of one or more rectangular areas, and includes information on the latitude and longitude of each rectangular area. Then, when the current position of the terminal is included in the danger zone and any of the above "condition 1" to "condition 3" is met, the emergency mode is entered. This method is suitable when the dangerous area where the transition to the emergency mode is required is limited. However, in order to define the third region R3, for example, a predetermined distance from the boundary between the safety region and the danger region to the inside of the safety region shall be defined.

Further, a fourth region R4 may exist in addition to the first region R1 to the third region R3. The fourth region R4 is a neutral region that is neither a safe zone nor a dangerous zone, and the state of the terminal device 1 up to that point is continued. When there is a fourth region R4, the first region R1 and the second region R2 do not have to be adjacent to each other.

<Embodiment 2>
The second embodiment is different from the first embodiment described above in the return process. Further, at that time, it is not necessary to determine whether or not it is within the third region R3. In the second embodiment, one of the following methods is used to release the emergency mode, that is, to return (transition) from the emergency mode to the normal mode. The position of the terminal device 1 may be in the safe area or the dangerous area.

(1) Perform a predetermined operation set in advance for the terminal device 1. For example, an operation of pressing a plurality of buttons in a predetermined order (sequence) is registered in advance, and the mode transitions to the normal mode only when the operation is performed in that sequence.
(2) Perform a predetermined release operation on the management terminal 2. When the release operation is performed on the management terminal 2, an emergency mode release instruction (state transition instruction) is transmitted to the terminal device 1 via the management server 3 and the network N, and the terminal device 1 transitions to the normal mode. The position of the management terminal 2 at that time may be in the safe area or the dangerous area.
(3) Communication between the user of the management terminal 2 and the user of the terminal device 1 is established. As the communication, a video call or a voice call is desirable. At this time, the management server 3 or the management terminal 2 may recognize the image or voice of the user of the terminal device 1 and authenticate that the user is a legitimate user. In addition, it may be recognized that the user of the terminal device 1 is not placed in a stress situation such as intimidation from the facial expression and the intonation of voice.

Since each configuration according to the second embodiment is the same on the drawings, the illustration is omitted. Regarding the state transition process, step S116 in FIG. 11, that is, the return process in FIG. 12 is assumed to be replaced with the following return processes 2-1 and 2-2.

<Return processing from emergency mode 2-1>
FIG. 14 is a flowchart showing the flow of the return process 2-1 from the emergency mode by the terminal device 1 according to the second embodiment. Here, it is assumed that the terminal device 1 has already transitioned to the emergency mode. Then, the terminal device 1 determines whether or not a predetermined release operation from the user has been detected (S141). For example, when a plurality of buttons are pressed in a predetermined order within a predetermined time, it is determined that a predetermined release operation has been performed. If it is determined in step S141 that a predetermined release operation has been detected, the battery level monitoring unit 134 determines whether or not the current battery level of the terminal device 1 is less than level 2 (S142).

When it is determined in step S142 that the remaining battery level is less than level 2, the operation mode control unit 131 shifts to the normal mode power OFF 2 state (S143). When it is determined in step S142 that the remaining battery level is level 2 or higher, the operation mode control unit 131 shifts to the normal mode power ON state (S144). After step S143 or S144, the process returns to A in FIG.

If it is determined in step S141 that the predetermined release operation is not detected, the process proceeds to step S117 of FIG.

<Recovery process from emergency mode 2-2>
FIG. 15 is a flowchart showing the flow of the return process 2-2 from the emergency mode by the management terminal according to the second embodiment. Here as well, it is assumed that the terminal device 1 has already transitioned to the emergency mode. Then, the user (administrator) of the management terminal 2 inputs a predetermined release operation for canceling the emergency mode of the terminal device 1 to the management terminal 2. Then, when the management terminal 2 detects the input of the release operation, it transmits an emergency mode release instruction to the terminal device 1 via the network N and the management server 3. It should be noted that, in the known public key cryptography, "signature" information indicating that the information is legitimately transmitted by the management server 3 or the management terminal 2 may be included in the release instruction.

Then, the terminal device 1 determines whether or not a predetermined release instruction has been received from the management terminal 2 via the management server 3 and the network N (S151). When it is determined in step S151 that a predetermined release instruction has been received, the battery level monitoring unit 134 determines whether or not the current battery level of the terminal device 1 is less than level 2 (S152).

When it is determined in step S152 that the remaining battery level is less than level 2, the operation mode control unit 131 shifts to the normal mode power OFF 2 state (S153). When it is determined in step S152 that the remaining battery level is level 2 or higher, the operation mode control unit 131 shifts to the normal mode power ON state (S154). After step S153 or S154, the process returns to A in FIG.

If it is determined in step S151 that the release instruction is not detected, the process proceeds to step S117 of FIG. By replacing step S151 with the process "Is the communication between the user of the management terminal 2 and the user of the terminal device 1 established?", The method (3) can be executed in the same manner.

As described above, also in the present embodiment, the danger due to the existence position of the portable wireless terminal device is considered, and the safety of the user of the terminal device can be improved.

<Embodiment 3>
The third embodiment is a combination of the first and second embodiments described above. That is, in the return process from the emergency mode, the return condition is that the current position of the terminal device is the third area and the release instruction from the management terminal is received. The configuration of the terminal device 1 in this embodiment is the same as the configuration of the terminal device 1 in the first embodiment shown in FIG.

In other words, the second transition unit 1312 according to the third embodiment is described when the own terminal device moves from the second region to the third region and receives a state transition instruction from the outside. The transition from the second state to the first state. As a result, the emergency mode is canceled by the operation of the administrator instead of the user of the terminal device 1, so that the safety can be further improved.

Further, in the second transition unit 1312 according to the third embodiment, the own terminal device moves from the second area to the third area, and the own terminal device and the management terminal can communicate with each other via the network. After being connected, it is preferable to transition from the second state to the first state. As a result, the management terminal confirms the state of the user of the terminal device 1 via the network, and then cancels the emergency mode, so that the safety can be further improved.

Further, regarding the state transition process, step S116 of FIG. 11, that is, the return process of FIG. 12 is assumed to be replaced with the following return process.

FIG. 16 is a flowchart showing the flow of the state transition process (mainly the return process from the emergency mode) according to the third embodiment. Here, it is assumed that the terminal device 1 has already transitioned to the emergency mode. First, similarly to FIG. 12, in step S121, the position determination unit 133 determines whether or not the terminal device 1 exists in the third region R3.

When it is determined in step S121 that the terminal device 1 exists in the third area R3, whether or not the terminal device 1 has received a predetermined release instruction from the management terminal 2 via the management server 3 and the network N. Is determined (S125). If it is determined in step S125 that a predetermined release instruction has been received, step S122 and subsequent steps in FIG. 12 are executed. If it is determined in step S125 that the release instruction is not detected, the process proceeds to step S117 of FIG.

Note that step S125 in FIG. 16 may be replaced with step S141 in FIG. 14, that is, "predetermined release operation detected?" (In the terminal device).
