The present invention has been made to solve the above problems.
The portable terminal of the present invention includes a transmission unit, a reception unit, an operation unit operated at the time of emergency notification,
When the operation unit is operated with a detection unit that detects a current position, current position information detected by the detection unit is transmitted to the center device by the transmission unit, and a predetermined signal is received by the reception unit. In this case, even if the operation unit is operated, the current position transmission control unit is configured not to transmit the current position information.
[0006]
According to the present invention, when the portable terminal is used properly, the emergency signal including the current position is displayed on the center device when the owner encounters an emergency and operates the operation unit, as in the conventional case. Sent. In the case where the mobile terminal is lost and notified, a predetermined signal for invalidating the operation of the operation unit of the mobile terminal is transmitted from the center device to the mobile terminal.
[0007]
Then, in the portable terminal, the emergency signal is not transmitted to the center device even if the operation unit is operated thereafter. Therefore, even if the mobile terminal is transferred to a malicious third party, it is possible to prevent the control operation and the communication traffic in the center device from increasing.
The present invention can be applied not only to an emergency signal when an operation unit is operated, but also to a portable terminal having a function of transmitting current position information to a center device when a request signal is received from the center device. it can. In this case, when the predetermined signal is received by the receiving unit, the emergency signal is not transmitted even if the operation unit is operated. However, when the request signal is received, the current position information is transmitted. I do.
[0008]
According to this example, not only can a large number of emergency signals be transmitted when the mobile terminal is lost, etc., but also a request signal is transmitted from the center device and current location information is obtained from the mobile terminal. Thus, it becomes possible to search for a portable terminal.

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described with reference to the drawings.
FIG. 1 shows a configuration of a mobile monitoring system to which a mobile terminal of the present invention is applied.
A center device 3 and a location information center 8 arranged in an emergency response center 1 that performs mobile body monitoring are connected to a communication network 2 such as the Internet, a public line network, and a dedicated network.
[0010]
The portable terminal 4 is carried by a person or mounted on a car. When the equipped emergency button is operated, or when a transmission request signal for the current position is received from the emergency response center 1, the portable terminal 4 uses the position information signal received from the GPS satellite 5 as a base station 6 and a communication network. 2 to the location information center 8. The position information center 8 receives error information of GPS satellites, position information of the base station 6 and the like from the satellite reference station 7 via the communication network 2 and calculates highly accurate position information of the mobile terminal 4 based on these. . The latitude / longitude information that is the calculated position information with high accuracy, that is, the current position information of the portable terminal 4 is returned to the portable terminal 4.
[0011]
The mobile terminal 4 that has received the current position information transmits the current position information to the emergency response center 1 together with an emergency signal or the like.
In the present embodiment, the current position information is transmitted from the portable terminal 4 to the emergency response center 1, but may be transmitted from the position information center 8 to the emergency response center 1.
[0012]
Further, in the present embodiment, the position information center 8 is used to improve the accuracy of the position information detected by the mobile terminal 4. However, if it is not necessary to increase the accuracy of the position information, the current position information detected by the mobile terminal 4 may be transmitted directly to the emergency response center 1.
Thereby, the emergency response center 1 can know the current position of the mobile terminal 4 in real time. When it is determined that some countermeasure is necessary, the center device 3 transmits necessary data to the predetermined countermeasure terminal 9 to instruct the counselor to deal with it. At this time, map information indicating the content of the countermeasure and the position of the target mobile terminal 4 is transmitted to the coping person.
[0013]
FIG. 2 shows the configuration of the mobile terminal 4.
The portable terminal 4 includes a logic unit 11 that includes a CPU and the like. The logic unit 11 includes a power supply unit and is connected to the battery pack 12. The logic unit 11 is further connected to an RF unit 13, a power switch 14, an emergency button 15, a buzzer 16, a vibrator 17, a communication LED 18, and an emergency LED 19.
[0014]
The RF unit 13 is connected to the antenna 21, receives a signal from the GPS satellite 5, a base station information signal, a request signal from the center device 3, etc., sends it to the logic unit 11, and is sent from the logic unit 11 Position information and the like are transmitted to the center device 3 and the position information center 8 through the base station 6.
The emergency button 15 is operated when a person holding the portable terminal 4 is attacked by a bandit or encounters an emergency such as a physical condition. When the emergency button 15 is operated, the logic unit 11 Notifies the center device 3 that the status has changed, that is, an emergency signal and position information.
[0015]
The power switch 14 is provided to switch the portable terminal 4 between an operating state and a non-operating state.
The buzzer 16, vibrator 17, communication LED 18, and emergency LED 19 perform display according to the state of the mobile terminal 4, but description thereof is omitted here.
The operation of the logic unit 11 will be described with reference to FIG.
[0016]
The illustrated process is started when the portable terminal 4 is in an operating state by the operation of the power switch 14. First, an outline of the processing flow of the entire diagram will be described.
In step S1, it is determined whether or not the emergency button has been operated. Here, if the emergency button 15 is operated, it is determined in step S2 whether or not the portable terminal 4 is suspended. If the operation is not stopped, an emergency signal is transmitted to the center device 3 in step S3.
[0017]
When the emergency signal transmission process in step S3 is completed, it is determined in step S1 that the emergency button is not operated, or it is determined in step S2 that the operation is stopped, the center in step S4 It is determined whether a signal is received from the device 3. If a signal has been received, processing corresponding to the received signal is performed in step S5, and the process returns to step S1. If no signal is received from the center device 3 in step S4, the process returns to step S1.
[0018]
Next, the process of FIG. 3 will be described for each case.
In addition, as a signal which the portable terminal 4 receives from the center apparatus 3 in step S4, the signal which confirms having received the emergency signal from the portable terminal 4 as a main thing, the signal which restores the emergency state of the portable terminal 4 There are a predetermined signal for instructing to stop the operation of the mobile terminal 4 and a request signal for requesting that the mobile terminal 4 transmit the current position information.
[0019]
(1) If there is no operation of the emergency button 15 and no signal is received from the center device 3, only the steps S1 (NO) and S4 (NO) are passed, and the portable terminal 4 does not perform any special processing.
(2) (a) When the emergency button is operated, the process proceeds from step S1 to step S2, and it is determined whether or not the operation is stopped (the operation stop will be described later). Since the portable terminal is not in the operation stop state during normal times, the process proceeds to step S3, and an emergency signal is transmitted to the center apparatus 3.
[0020]
The emergency signal includes information for identifying the portable terminal 4, an indication that an emergency has occurred, and the latitude and longitude of the current position information. Moreover, the portable terminal 4 rings the buzzer 16 for a predetermined time and blinks the emergency LED 19.
As the current position information, latitude / longitude is acquired based on a signal received from the GPS satellite 5, and the latitude / longitude is transmitted as a position information signal. The current position information signal calculated by the position information center 8 based on this position information is processed as already described with reference to FIG. 1, and the portable terminal 4 notifies the center device 3. Until the portable terminal 4 receives a signal from the center device 3, the portable terminal 4 exits from NO in step S4 and repeats the processes from the above steps S1 to S4.
[0021]
(B) When the center device 3 receives an emergency signal from the mobile terminal 4, the emergency response center 1 issues an instruction to the responder to rush to the site. Moreover, the signal which notifies that the emergency signal was received with respect to the applicable portable terminal 4 is transmitted.
When receiving this signal (YES in step S4), the portable terminal 4 changes the emergency LED 19 from blinking to lighting as a process corresponding thereto (step S5), and vibrates the vibrator 17 for a predetermined time. Thereby, the holder of the portable terminal 4 can confirm that the emergency signal has arrived at the emergency response center 1.
[0022]
(C) Upon receiving the emergency signal in step S3, the center device 3 thereafter transmits a request signal to the portable terminal 4 at predetermined intervals until receiving a notification of the end of the response from the operator. When the mobile terminal 4 receives this request signal (YES in step S4), the mobile terminal 4 transmits the current position information to the center device 3 as a process corresponding to the request signal (step S5). Thereby, even if the portable terminal 4 moves, the emergency response center 1 can track this and cope with it.
[0023]
(D) After that, when the counselor rushes to the site to take action and reports that the emergency has been canceled, the center device 3 sends a signal for restoring the emergency state to the corresponding portable terminal 4 Is done.
When the portable terminal 4 receives this signal (YES in step S4), the emergency LED 17 is turned off as a process corresponding to the signal (step S5). Thereby, the portable terminal 4 returns to a normal state. The communication LED 18 blinks when the mobile terminal 4 is communicating.
[0024]
(3) (a) When the mobile terminal 4 is lost or stolen and the emergency response center 1 is notified, a predetermined signal instructing the operation of the mobile terminal 4 to be stopped is sent from the center device 3 to the mobile terminal 4 Sent to. When the portable terminal 4 receives this signal (YES in step S4), the portable terminal 4 is set to an operation stop state as a process corresponding thereto (step S5).
[0025]
When the mobile terminal 4 is set to the operation stop state in this way, the emergency button 15 is operated and when the process proceeds from step S1 to step S2, it is determined that the operation is stopped here, so the process proceeds to step S4, and step S3. Does not proceed to emergency signal transmission processing. Therefore, even if a person who picks up or steals the mobile terminal 4 operates the emergency button 15 of the mobile terminal 4, no emergency signal is transmitted to the center device 3. Thereby, it is possible to prevent the control operation and communication traffic from increasing in the center device 3.
[0026]
(B) The center device 3 transmits a request signal to the mobile terminal 4 after invalidating the operation of the mobile terminal 4. When the portable terminal 4 receives this request signal (YES in step S4), it transmits the current position information to the center device as a process corresponding to the request signal (step S5). Thereby, the current position of the mobile terminal 4 that has been lost or stolen is determined. Therefore, even if the operation of the mobile terminal 4 is invalidated, the mobile terminal 4 can be searched.
[0027]
(4) When a person carrying the mobile terminal 4 is missing or when a car equipped with the mobile terminal 4 is stolen, a request signal is sent from the center device 3 to the mobile terminal 4 concerned. Sent. If the portable terminal 4 that has received the request signal determines that it has received the request signal in step S4, it transmits the current position information to the center device 3 in step S5. This makes it possible to search for missing persons, stolen vehicles, and the like.
