Hereinafter, a portable terminal of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the configuration of a safety confirmation system using a portable terminal of the present invention. In the safety confirmation system, a portable terminal 1 possessed by a monitoring target person and a center device 4 arranged in a monitoring center 3 that monitors the monitoring target person are connected to a communication network 2 such as a mobile phone network, the Internet, or a dedicated network. The
The portable terminal 1 is possessed by a person to be monitored. When the mobile terminal 1 calculates position information composed of latitude / longitude information from the GPS signal received from the GPS satellite 5 and the operation target at the specified time is not operated after the monitoring target person performs the start operation of the monitoring operation. The current position information is transmitted together with the abnormality signal to the center device 4 installed in the monitoring center 3 via the communication network 2.
Furthermore, when the monitoring subject operates the emergency notification switch of the portable terminal 1 when an emergency occurs, the current position information is transmitted to the center device 4 of the monitoring center 3 together with the emergency signal.

The center device 4 of the monitoring center 3 is a device that receives a report from the mobile terminal 1 and confirms the location information of the mobile terminal 1. The center device 4 is managed and operated by an organization that provides a safety confirmation service to a plurality of target persons, such as a monitoring center of a security company. In the monitoring center 3, it is possible to know the emergency situation and the current position that occurred in the monitoring subject who owns the mobile terminal 1, and when it is determined that some countermeasure is necessary, the center device 4 sends a predetermined countermeasure terminal 7. Send the necessary data to instruct the coordinator to take appropriate measures for the person being monitored. At this time, a map indicating the content of the countermeasure and the position of the target mobile terminal 1 is transmitted to the coping person.
In addition, the monitoring center performs processing such as a 110th report and a 119th report and a telephone call with the monitoring target person or a predetermined emergency contact address as necessary according to an emergency situation that has occurred to the monitoring target person.

For example, when there is an emergency call from the mobile terminal 1 to the monitoring center 3, the monitor transmits a tracking signal from the center device 4 to the mobile terminal 1. The mobile terminal 1 that has received such a tracking signal sequentially acquires the current position and returns it to the center device 4 at predetermined time intervals. In this way, by grasping the current position of the mobile terminal 1 at the monitoring center 3, it is possible to appropriately monitor the person to be monitored and protect the person to be monitored by appropriately sending a coping person to the site.
Here, the coping person possesses the coping terminal 7, and monitors and protects the person being monitored by looking at the current position transmitted from the center apparatus 3 to the coping terminal 7.

Next, the configuration of the mobile terminal 1 will be described. FIG. 2 is a diagram illustrating functional blocks of the mobile terminal 1.

Further, the determination unit 110 determines whether or not the mobile terminal 1 is in a state in which the mobile terminal 1 can reliably communicate with the base station 6 based on the electric field strength of the radio wave received from the base station 6 via the RF unit. Unit 111 and a remaining battery level determining unit 112 that determines whether or not communication is possible based on a voltage drop of the power supply voltage supplied from the battery.

The operation unit 104 includes a power switch and an emergency call switch.
Various operations are performed by combining the operations of the two switches. For example, the power switch is operated continuously for a predetermined time (for example, 3 seconds or more), thereby switching between power ON for turning on the mobile terminal 1 and power OFF for not operating. The emergency call switch is a slide switch. When the power is turned on, the emergency call operation is started by sliding the switch up and turning it on.
Further, for a predetermined time (for example, 1 minute) after the power is turned on by operating the power switch, the communication state determination unit 111 enters a radio wave state check mode in which the mobile terminal 1 checks whether or not communication with the base station 6 is possible. . When the mobile terminal 1 enters the radio wave check mode, the communication state determination unit 111 can communicate with the monitoring center 3 via the base station 6 (that is, whether or not radio waves necessary for wireless communication can be reliably received). to decide. Then, according to the result, the display unit 106 and the buzzer 107 are sounded to display whether communication is possible or communication is not possible outside the radio wave range.

The person to be monitored starts the monitoring operation of the mobile terminal 1 by operating the power switch twice within a predetermined time (for example, 1 second) when the mobile terminal 1 is powered on. Moreover, when ending the monitoring operation, the monitoring operation of the portable terminal 1 is ended by continuously operating the power switch for a predetermined time (for example, 3 seconds or more) during the monitoring operation.
When the monitoring operation is started, the mobile terminal 1 is controlled by the control unit 100 so that the power cannot be turned off until the monitoring operation is completed.
In addition, even after the monitoring operation is started, the mobile terminal 1 can activate the emergency notification operation by sliding the emergency notification switch upward (ON).

Next, the configuration of the center device 4 installed in the monitoring center 3 will be described. FIG. 3 is a diagram illustrating functional blocks of the center device 4. The center device 4 includes a control unit 41 configured by a computer including a microprocessor (MPU), a semiconductor memory, and an interface circuit, and a storage unit 42 as a storage area. , An operation unit 43 including a mouse and a keyboard, a display unit 44 including a CRT (CRT), a communication unit 45 including a transmitter and a receiver, and an alarm unit 46.

The alarm unit 46 includes an amplifier circuit and a speaker, receives an alarm signal, amplifies it, and outputs the alarm sound from the speaker.

Next, the operation of the mobile terminal 1 will be described in detail with reference to the operation flowchart shown in FIG.
The storage unit 105 of the portable terminal 1 stores in advance a predetermined time T for the monitoring operation, that is, a time until an emergency is determined during the monitoring operation.
The storage unit 105 of the portable terminal 1 stores a first predetermined time T1 (T1 <T) and a second predetermined time T2 (T1 <T2 <T) in addition to the above-mentioned specified time T. Yes. The first predetermined time T1 and the second predetermined time T2 are used to inform the monitoring subject in a stepwise manner of the passage of time with respect to the specified time T.
The specified time T, the first predetermined time T1, and the second predetermined time T2 can be set to any time by operating the operation unit 104 of the portable terminal 1, and from the center device 4 or an external terminal (not shown) For example, it can be downloaded and set to the mobile terminal 1 using a mail service of a mobile phone company.

In this embodiment, an example in which the specified time T is set to 2 minutes, the first predetermined time T1 is set to 1 minute, and the second predetermined time T2 is set to 1 minute 30 seconds will be described. However, T1 <T2 <T It may be set in any way as long as the above is satisfied.
Further, the storage unit 42 of the center device 4 has specified time information for monitoring requests for each portable terminal 1 owned by the monitoring subject, the name, age, image, characteristics, address, emergency contact telephone number, etc. of the monitoring subject. Is stored.

For example, when the monitoring target starts monitoring operation of the mobile terminal 1 on the way home, or when a suspicious person visits a store managed by the monitoring target, the power switch that is the operation unit 104 of the mobile terminal 1 is turned on. The operation is performed twice within a predetermined time (for example, 1 second). The control unit 100 of the portable terminal 1 detects that a monitoring operation start operation has been performed, and starts the monitoring operation (step S001).
In the present embodiment, the start operation and the end operation of the monitoring operation are performed using the power switch. However, the present invention is not limited to this, and a switch for performing the monitoring operation start operation and the monitoring operation end operation is separately provided. It may be.

When starting the monitoring operation, the control unit 100 of the mobile terminal 1 operates the GPS receiving unit 102 at intervals of 1 minute, for example, receives a GPS signal from the GPS satellite 5, and receives the current position information from the latitude / longitude of the mobile terminal 1 Is stored in the storage unit 105 together with the calculated time information (step S002). This is continued until the monitoring operation ends.

Next, the control unit 100 starts measuring the specified time T described above, that is, the time T (for example, 2 minutes) until an abnormality is determined during the monitoring operation (step S003).
The monitoring subject operates the power switch of the operation unit 104 of the mobile terminal 1 continuously for a predetermined time (for example, 3 seconds or more) and monitors when the monitoring operation is terminated due to a safe return or when a suspicious person leaves. The operation end operation is performed (step S004).
When there is a monitoring operation end operation (step S004—Yes), the portable terminal 1 resets the time count by the control unit 100, ends the calculation and storage of the position information, and ends the monitoring operation.

Further, during the monitoring operation of the mobile terminal 1, the monitoring subject operates the power button of the operation unit 104 for a predetermined time (for example, within 1 second) in order to periodically input safety confirmation to the mobile terminal 1. A safety confirmation operation is performed (step S005).
When there is a safety confirmation operation (step S005-Yes), the portable terminal 1 resets the time count by the control unit 100, and starts time count again.

Here, when the monitoring operation end operation and the safety confirmation operation are not performed (steps S004-No, step S005-No) and the time measured by the control unit 100 reaches a predetermined first predetermined time T1 (1 minute). (Step S006 Yes), the vibrator 108 is vibrated with the first vibration pattern (for example, vibrated once every 10 seconds) and displayed on the display unit 106. The portable terminal 1 informs the person to be monitored that the first predetermined time T1 has elapsed by the operation of the vibrator 108 and the display unit 106 and requests a safety confirmation operation (step S007).
The notification operation by the vibrator 108 and the display unit 106 is continuously performed until there is a safety confirmation operation or a monitoring end operation, or until the control unit 100 measures the second predetermined time T2 (1 minute 30 seconds).
When notifying the first predetermined time T1 when the communication state determination unit 111 determines that the communication is not possible, the control unit 100 notifies the user with a different notification operation pattern. For example, a message indicating that communication is not possible is displayed on the display unit 106, and the vibration pattern of the vibrator 108 is different from the first vibration pattern (for example, continuously vibrated twice every 10 seconds). It notifies that it cannot communicate with the center device 4.

At this time, depending on the remaining battery level determined by the remaining battery level determination unit 112, the vibrator 108 or the display is displayed depending on whether the remaining battery level is sufficient or the battery level is insufficient and the battery will soon be exhausted. The notification operation by the unit 106 may be varied.

The portable terminal 1 notifies that the first elapsed time T1 has elapsed, and waits for the monitoring operation end operation and the safety confirmation operation by the monitoring target person (steps S008 and S009).
When there is a monitoring operation end operation (step S008-Yes), the time count by the control unit 100 is reset, the calculation and storage of the position information is ended, and the monitoring operation is ended. On the other hand, when there is a safety confirmation operation (step S009-Yes), the time count by the control unit 100 is reset and time count is started again.

Here, the second predetermined time T2 (1 minute 30 seconds) in which the time measurement by the control unit 100 is determined in advance without performing the monitoring operation end operation and the safety confirmation operation (step S008-No, step S009-No). Then (step S010-Yes), the vibrator 108 is vibrated with the second vibration pattern (for example, vibrated once every 3 seconds) and displayed on the display unit 106. The portable terminal 1 informs the monitoring subject that the second predetermined time T2 has passed and soon becomes the specified time T by the operation of the vibrator 108 display unit 106, and requests a safety confirmation operation (step S011).
The notification operation by the vibrator 108 and the display unit 106 is continuously performed until there is a safety confirmation operation or a monitoring end operation, or until the control unit 100 measures the specified time T (2 minutes).
When the communication state determination unit 111 determines that the communication is impossible when the second predetermined time T2 is notified, the control unit 100 makes a notification by changing the notification operation pattern. For example, a message indicating that communication is not possible is displayed on the display unit 106, and the vibration pattern of the vibrator 108 is different from the second vibration pattern (for example, continuously vibrated twice every 3 seconds). It notifies that it cannot communicate with the center device 4.

At this time, depending on the remaining battery level determined by the remaining battery level determination unit 112, the vibrator 108 or the display is displayed depending on whether the remaining battery level is sufficient or the battery level is insufficient and the battery will soon be exhausted. The notification operation by the unit 106 may be varied.

The portable terminal 1 notifies that the second elapsed time T2 has elapsed, and waits for the monitoring operation end operation and the safety confirmation operation by the monitoring target person (steps S012 and S013).
When there is a monitoring operation end operation (step S012-Yes), the time counting by the control unit 100 is reset, the calculation and storage of the position information is ended, and the monitoring operation is ended. On the other hand, when there is a safety confirmation operation (step S013-Yes), the time measurement by the control unit 100 is reset and time measurement is started again.

Here, when the monitoring operation end operation and the safety confirmation operation are not performed (step S012-No, step S013-No) and the time measured by the control unit 100 reaches a predetermined time T (2 minutes) (step S014). -Yes), the control unit 100 determines that an emergency has occurred in the monitoring target person, stops the vibration of the vibrator 108, and displays on the display unit 106. The portable terminal 1 notifies the monitoring subject that the occurrence of an emergency has been detected by the operation of the vibrator 108 and the display unit 106 (step S015).

When the controller 100 detects the occurrence of an emergency, the controller 100 reads position information measured at predetermined time intervals during the monitoring operation, adds a unique identification code of the mobile terminal 1, and sends an abnormality from the transmitter / receiver 103 and the RF unit 101. It transmits to the center apparatus 4 as a signal (step S016).
When the occurrence of an emergency situation is detected, the portable terminal 1 is latched and controlled by the control unit 100 so that the monitoring operation cannot be terminated unless a recovery signal is received from the center device 4.

At this time, if the communication state determination unit 111 determines a state in which communication is not possible, the control unit 100 stores the time when the emergency occurred in the storage unit 105. Then, when the communication state determination unit 111 determines that communication is possible, the control unit 100 determines the time at which an abnormal situation has occurred from the storage unit 105 and the position measured at predetermined time intervals during the monitoring operation and after the occurrence of the abnormal situation. The information is read out, the unique identification code of the portable terminal 1 is attached, and transmitted from the transmission / reception unit 103 and the RF unit 101 to the center device 4 as an abnormal signal.

When the center device 4 of the monitoring center receives an abnormality signal from the mobile terminal 1, it transmits an abnormality confirmation signal to the mobile terminal 1.
When the portable terminal 1 receives the abnormality confirmation signal from the center device 4 (step S017—Yes), the portable terminal 1 vibrates the vibrator 108 and displays it on the display unit 106. The portable terminal 1 notifies that the abnormal signal has been delivered to the monitoring center 3 (center device 4) by the operation of the vibrator 108 and the display unit 106 (step S018).

In the monitoring center 3, when an abnormality signal is received by the center device 4, an alarm signal is output to the alarm unit 46, map information indicating the movement locus of the mobile terminal 1, the name, characteristics, address, mobile terminal of the person to be monitored The data such as the telephone number and the emergency contact telephone number are displayed on the display unit 44. Upon receiving the alarm signal, the alarm unit 46 outputs an alarm sound from the speaker. When the center device 4 receives an abnormal signal from the mobile terminal 1, the center device 4 transmits a tracking signal to the mobile terminal 1, and receives a response of current position information sequentially from the mobile terminal 1 every predetermined time, and thus the monitoring target The position of the person.

In the monitoring center 3, an instruction is given to the coordinator closest to the current position of the monitoring target person, and the name, age, characteristics, address, etc., along with the current position information of the monitoring target person, are displayed on the handling terminal 7 possessed by the coping person Searching is facilitated by sending and displaying necessary information for searching.
In addition, the monitoring center 3 transmits a recovery signal to the mobile terminal 1 when it is no longer necessary to track the position of the monitoring subject.

When the mobile terminal 1 receives the recovery signal from the center device 4 (step S019—Yes), the mobile terminal 1 releases the control latched due to the occurrence of the abnormal situation, ends the calculation and storage of the position information, and ends the monitoring operation.

In the above-described embodiment, when the mobile terminal 1 starts the monitoring operation, the control unit 100 of the mobile terminal 1 calculates the current position information every predetermined time and stores the processing in the storage unit 105 together with the time information. Is executed until the process ends (step S002 in FIG. 4), but is not limited to this.
For example, the process of step 002 in FIG. 4 is skipped, and when the occurrence of an abnormal situation is detected (step S015 in FIG. 4), current position information is calculated, and an abnormal signal is transmitted using the calculated current position information. (Step 016 in FIG. 4) may be configured.
Thereby, the portable terminal 1 can eliminate the process of calculating the current position information every predetermined time from the start of the monitoring operation, and can reduce power consumption.

Further, in the present embodiment, notification of the first predetermined time T1 (step S007 in FIG. 4), notification of the first predetermined time T2 (step S011 in FIG. 4), detection notification of the abnormal situation (step S015 in FIG. 4). ), The notification operation by the notification of reception of the abnormality confirmation signal (step S018 in FIG. 4) is performed by the vibrator 108 or the display unit 106. However, this notification operation may be performed by the sound of the buzzer 107. Good.
In this case, similarly to the notification operation by the vibrator 108, the battery remaining amount is insufficient for each notification operation described above and when the communication state determination unit 111 determines that communication is impossible or the battery remaining amount determination unit. When it is determined that there is, it is preferable that the ringing pattern is changed and notified.

Further, in this embodiment, the elapsed time with respect to the specified time T is notified in two steps step by step with the first predetermined time T1 and the second predetermined time T2, but the present invention is not limited to this. is not. For example, the notification may be made in more stages, and the elapsed time may be notified in one stage only by the first predetermined time T1.

Further, in the present embodiment, the monitoring operation is started by operating the operation unit 104 when the power of the mobile terminal 1 is ON. However, the monitoring operation is performed even when the power of the mobile terminal 1 is OFF. When the start operation is input, the power may be turned on to start the monitoring operation. Further, even when the power of the mobile terminal 1 is OFF, when the emergency notification switch is turned ON, the power may be turned ON to start the emergency notification operation.

In the present embodiment, the monitoring center 3 is configured to output an alarm when the center device 4 receives an abnormal signal. However, the present invention is not limited to this, and the center device 4 receives an abnormal signal from the portable terminal 1. May be transmitted to the portable terminal 1 to prompt the response to the person to be monitored, and when there is no response, an alarm may be given and the portable terminal 1 may be made to transmit the current position information.

Therefore, according to the mobile terminal 1 configured as described above, since the elapse of time can be notified before the stipulated time T elapses, a safety confirmation operation can be requested to the monitoring subject. It is possible to prevent the confirmation operation from forgetting the specified time T and prevent unnecessary notifications.
Further, according to the mobile terminal 1 of the present embodiment, before the specified time T elapses, the passage of time can be notified in two different patterns and a safety confirmation operation can be requested to the monitoring subject. The person to be monitored can know the remaining time until the specified time T by the change of the notification pattern, and can effectively request the operation.
Furthermore, according to the mobile terminal 1 of the present embodiment, since the notification pattern according to the passage of time is made different depending on whether or not the communication can be reliably performed based on the radio wave condition or the remaining battery level, Whether the communication with the monitoring center 3 is possible or not can be recognized by the change of the notification pattern due to the buzzer or the buzzer.
In addition, according to the mobile terminal 1 of the present embodiment, since the power of the mobile terminal 1 cannot be turned off during the monitoring operation, the power of the mobile terminal 1 is prevented from being turned off by a bandit or the like, thereby improving the monitoring reliability. Can be made. Furthermore, since the monitoring operation cannot be terminated when the mobile terminal 1 detects the occurrence of an emergency, the monitoring target can be reliably monitored.

In addition to safety confirmation when passing by individuals, it can also be applied to the safety confirmation of transporters who carry important items such as cash and precious metals.
