Referring to FIG. 8, the control unit 101 of the present invention determines whether or not the wearable electronic device 100 has left the safe area S1 through the GPS device 170 or the communication unit 180. Here, the safe area S1 means an area where the wearer can safely operate. The safe area S1 can basically be set as a physical specific space. Specifically, the safe area S1 may be a space in which the user of the wearable electronic device 100 of the present invention resides, and a space within a predetermined distance from the facility. For example, if the wearer is a patient accommodated in a nursing hospital, the safety zone S1 may be a hospital accommodated and its surrounding space. The information on the safe area S1 is stored in the memory 130 of the wearable electronic device 100 in advance. The information on the safety zone S1 can be changed by the wearer or the caregiver or administrator of the wearer to an appropriate range.

If the wearable electronic device 100 of the present invention determines that the wearable electronic device 100 has deviated from the safe region S1, the control unit 101 displays the emergency information through the display unit 140, . Emergency information may include facility information residing by the wearer. Specifically, the emergency information may include information about the name, location, telephone number, other contact information of the facility where the wearer resides, and the manager of the wearer. For example, if the wearer is a patient accommodated in a nursing home, the emergency information may include the name, location, phone number, other contact, the contact of the nurse or caregiver in charge, and the contact information of the caregiver. In addition, the emergency information may include personal information of the wearer. Specifically, the emergency information may include at least one of the name, age, sex, and symptoms of the wearer. More specifically, the symptoms of the wearer and the matters to be taken into consideration may be included.

Accordingly, when the wearer of the wearable electronic device 100 of the present invention moves out of the safe range S1, the display unit 140 of the wearable electronic device 100 displays the emergency information. The displayed emergency information may function to guide the wearer of the situation so that a third party in the vicinity can easily recognize it and take action. For example, when the wearer is a patient accommodated in a nursing hospital and the wearer wanders away from the hospital by unauthorized departure, a third party who finds the wearer, through the emergency information displayed on the wearable electronic device 100 display unit 140 of the present invention And can be handed over to a hospital where the wearer is accommodated.

A method for determining whether or not the wearable electronic device 100 of the present invention has departed from the safe region S1 is as follows.

First, the wearable electronic device 100 of the present invention can determine whether or not the safety zone S1 is deviated by using the GPS device 170 that senses the position. The GPS device 170 can sense the current position as a specific coordinate. In this case, the safety zone S1 information may be information on the position. Specifically, the safety area S1 information can be set to a range of a space expressed by specific coordinates. More specifically, the safety zone S1 information may be location information of a facility in which the wearer resides and a range within a predetermined distance from the facility, and may be set in various types of areas in consideration of the surrounding environment of the facility . For example, if the wearer is a patient accommodated in a nursing hospital, the safety zone S1 information may be information corresponding to a specific space around the accommodated hospital. In this case, the control unit 101 may compare the position coordinates detected by the GPS device 170 with the safety area S1 information stored in the memory 130 to determine whether or not the wearable electronic device 100 is detached. When the control unit 101 determines whether or not the safety zone S1 is detached based on the position sensed by the GPS device 170, the current position of the wearable electronic device 100 can be relatively accurately grasped, ) There is an advantage that the judgment of the departure is accurate. However, when the GPS device 170 is used, the power consumption of the GPS device 170 increases the overall power consumption of the wearable electronic device 100 of the present invention. In addition, since the wearable electronic device 100 has to be equipped with the GPS device 170, there is a disadvantage that the overall size can be increased.

Alternatively, the control unit 101 of the wearable electronic device 100 of the present invention can determine whether or not the safety zone S1 is detached through the connection of the communication unit 180. [ Specifically, the communication unit 180 may be connected to the wireless relay facility through wireless communication. In this case, it is also possible that the wearable electronic device 100 does not include the GPS device 170. [ As a result, the power consumption of the wearable electronic device 100 can be reduced and the wearable electronic device 100 can be miniaturized. In this case, the safety zone S1 information may be information on the coverage of the first radio relay facility to which the communication unit 180 is connected. Here, the first radio relay facility may be a radio relay facility installed in a facility where the wearer resides. The coverage of the first radio relay facility can be set to maximally match the safety zone S1 to be set. For this purpose, the connection conditions of the radio relay facility of the communication unit 180 and the output power of the radio relay facility can be adjusted. More specifically, when the wearable electronic device 100 is in the safe area S1, the control unit of the wearable electronic device 100, the wireless relay facility, and the wireless relay facility determines that the communication unit 180 is connected to the internal wireless relay facility And when the wearable electronic device 100 deviates from the safety zone S1, the communication unit 180 can be adjusted to be disconnected from the internal wireless relaying facility and connected to the external wireless relaying facility. To this end, if the wearable electronic device 100 is located within the coverage of the internal wireless relaying facility, it is preferable that the communication unit 180 is connected to the internal wireless relaying facility. And the outside of the coverage of the internal radio relay facility is preferably the coverage of the external radio relay facility. Accordingly, when the communication unit 180 is connected to the internal wireless relaying facility, the control unit 101 determines that the wearable electronic device 100 is in the safe area S1. When the communication unit 180 is disconnected from the internal wireless relaying facility or connected to the external wireless relaying facility, the control unit 101 determines that the wearable electronic device 100 has deviated from the safe area S1.

In this way, it is advantageous in that power consumption can be relatively reduced by detecting whether or not the GPS unit 170 is disconnected according to the connection state of the radio relay facility of the communication unit 180 without using the GPS unit 170 separately. In addition, the GPS device 170 can detect whether the GPS device 170 has departed from an indoor space or an underground space where it is difficult to sense the position. However, there is a disadvantage that it is difficult to perfectly match the safety zone S1 in which the coverage of the internal radio relay facility is set. Also, there is a disadvantage that the coverage of the internal radio relay facility may be unintentionally changed depending on the surrounding environment. In addition, it is difficult to form a safe area in a specific form other than a regular form.

9 is a flowchart illustrating a control method considering a safe area in a wearable electronic device according to an embodiment of the present invention. A control method of the wearable electronic device according to an embodiment of the present invention will be described with reference to FIG. In describing the control method of the wearable electronic device for convenience of explanation, the same contents as the description of the wearable electronic device described above with reference to Figs. 1 to 8 are omitted.

Referring to FIG. 9, the control method of the wearable electronic device of the present invention includes a step S100 of storing safety area information and emergency information, a step S200 of determining whether or not the safe area is detached, S300).

The step S100 of storing the safe area information and the emergency information is a step of storing the safe area information and the emergency information in the memory 130 of the wearable electronic device 100. [ The caregiver or administrator of the wearer or wearer may store safety zone information and emergency information in the memory 130 of the wearable electronic device 100. [ At this time, a dedicated terminal for storing may be used. Safety zone information and emergency information can be changed as needed.

The step S200 of determining whether or not the safe area is detached is a step of determining whether the wearable electronic device 100 has deviated from the safe area stored in the memory 130. [ The determination as to whether or not the safe area is separated may be made based on a method of determining based on a position sensed by the GPS device 170, a method of determining based on a state of the communication unit 180 being connected to a wireless relay facility, A method of first determining based on the state connected to the facility and a method of determining based on the position sensed by the GPS device 170 may be used.

The step S300 of setting the security of the lock unit is a step of restricting the unlocking operation of the lock unit 160 in the control unit 101 when it is determined that the wearable electronic device 100 has deviated from the safe area. At this time, as a security setting for restricting unlocking, various methods can be used, such as a method of blocking the electric current flowing in the lock having a magnetism or fixing the jog shuttle for unlocking, as described above. In addition, when it is determined that the wearable electronic device 100 has deviated from the safe area, the emergency information can be displayed on the display unit 140. [ Here, the emergency information may include information about the name, location, telephone number, other contact information of the facility where the wearer resides, and the manager of the wearer.

In some cases, step S80 of measuring the biological signal and step S90 of displaying the measurement result may be performed before the wearable electronic device 100 determines that the wearable electronic device 100 has deviated from the safe area. The wearable electronic device 100 includes a bio-signal measuring unit 150, and the bio-signal measuring unit 150 can measure a bio-signal of the wearer. And the measurement result of the living body signal can be displayed on the display unit 140. In addition, the measured biometric signal data can be transmitted to the patient management server or the personal portable terminal through the communication unit 180.
