2 is a block diagram illustrating the configuration of a wearable electronic device according to an embodiment of the present invention. 2, the wearable electronic device 100 of the present invention includes a memory 110, a display unit 120, a departure detection unit 130, a bio-signal measuring unit 140, a GPS device 150, a communication unit 160 , An alarm unit 170, and a battery 180. [

The memory 110 stores various kinds of information processed in the wearable electronic device 100 of the present invention. Specifically, the memory 110 may store safety zone information, emergency information, and various other information processed by the electronic device. The safe area information and emergency information stored in the memory 110 will be described in more detail below.

The memory 110 generally stores data using an auxiliary memory such as a main memory or a flash memory in the form of a storage medium such as a RAM (Random Access Memory) and a ROM (Read Only Memory), and an electric, magnetic, optical or other storage medium And the like. Further, the main memory may include a display unit memory for displaying information through the display unit. It will be apparent to those skilled in the art that the memory 110 may have various forms as a product having various storage performances.

The display unit 120 displays various information stored in the memory 110. [ The display unit 120 may be a display device for visually outputting information. The display unit 120 may be a display device capable of displaying characters or images such as a light emitting diode (LED), a liquid crystal display (LCD), or an electronic paper . In some cases, the display unit 120 may also include a transducer such as a speaker.

Particularly, when the display unit 120 is formed of electronic paper, power consumption can be greatly reduced, and it is relatively easy to form the display unit 120 with a curved surface. The electronic paper is realized by an electronic ink (e-ink), which is an ink made by using the electromagnetic properties of a particle, and is made up of millions of round small capsules. The small capsule contains a blue dye and a small chip in a transparent sheath and is placed between two layers of conductors. A small capsule between the transparent conductors will display the information while receiving positive and negative electrical signals.

The departure detection unit 130 determines whether or not the wearable electronic device 100 of the present invention has departed from the safe area. The determination by the departure detection unit 130 whether or not the electronic device has departed from the safe area will be described in more detail below. When the departure detection unit 130 determines that the electronic device has deviated from the safe area, the display unit 120 displays the emergency information stored in the memory 110. [

The bio-signal measuring unit 140 can measure the vital sign of the wearer. The bio-signal measuring unit 140 may measure, for example, the wearer's heart rate, oxygen saturation, the number of walking steps, body temperature, electrocardiography, and blood pressure. The bio-signal measuring unit 140 includes at least one sensor capable of measuring the bio-signal according to a bio-signal to be measured. The sensor may be a stationary sensor mounted within the wearable electronic device, but may also use a removable sensor that is removable whenever necessary. The deviation detecting unit 130 and the bio-signal measuring unit 140 may be configured in the form of a single substrate or a central processing unit.

The GPS device 150 is a global positioning system device and can sense the location of the GPS device 150 using the satellite. The GPS device 150 can sense the current position as a specific coordinate. By using the GPS device 150, the position of the wearable electronic device 100 of the present invention can be grasped relatively accurately.

The communication unit 160 is a device capable of wireless communication with another device. The communication unit 160 can transmit various data processed by the wearable electronic device 100 of the present invention to another device or receive data from another device.

Also, the communication unit 160 may use LoRa or NarrowBand-Internet of Things (NB-IoT), which is a large-scale low-power long-distance wireless communication technology. This large-scale low-power long-range wireless communication technology has advantages such as low standby power and low module price, so that it can be used efficiently in smart city and outdoor. In particular, unlike existing smart devices that require a high-speed, broadband network, a chip can be embedded in a terminal without a separate base station or relay device, enabling small-sized data to be exchanged at low power. In addition, LoRa technology has the advantage of maintaining the battery life of the terminal for several years because of its wide communication distance (maximum 21Km in the visible range) and low power consumption, and it has many AP (Access Point) There is an advantage in that the infrastructure cost can be lowered because no repeater is needed.

The alarm unit 170 is an apparatus that generates an alarm and makes a wearer or a third person around the wearer perceive an alarm situation.

The alarm unit 170 may generate an alarm by sound, light, or vibration.

In addition, the wearable electronic device 100 of the present invention includes the memory 110, the display unit 120, the departure detection unit 130, the bio-signal measurement unit 140, the GPS device 150, the communication unit 160, And a battery 180 capable of operating the alarm unit 170 and the like. The battery 180 supplies power to the above-described electronic component. The battery 180 may be a rechargeable battery.

FIG. 3 and FIG. 4 show the use state of the wearable electronic device according to an embodiment of the present invention. Referring to Figs. 3 and 4, it is sensed that the wearable electronic device 100 has deviated from the safe region S1, and the result is how the electronic device operates.

Referring to FIG. 3, the wearable electronic device 100 of the present invention determines whether or not the departure detection unit 130 has departed from the safe region S1. 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. Information about the safe area S1 is stored in advance in the memory 110 of the wearable electronic device 100. [ 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.

Referring to FIG. 4, the display unit 120 displays emergency information when the detachment detecting unit 130 determines that the wearable electronic device 100 of the present invention is out of the safe range S1. 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 120 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 a 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 can use the emergency information displayed on the wearable electronic device 100 display unit 120 of the present invention And can be handed over to a hospital where the wearer is accommodated.

Referring to FIG. 4, the alarm unit 170 may generate an alarm when the wear detection unit 130 determines that the wearable electronic device 100 of the present invention is to leave the safe area S1. A third party in the vicinity of the wearer can easily recognize that the wearer wears the electronic apparatus of the present invention and the emergency information is displayed on the display unit 120 by the alarm of the alarm unit 170. [ FIG. 4 shows that the alarm unit 170 is a light emitting unit, the emergency information is displayed on the display unit 130, and the light emitting unit emits light.

5 to 7 illustrate a use state of the wearable electronic device according to an embodiment of the present invention. 5 to 7, various embodiments for determining whether or not the wearable electronic device 100 has departed from the safe zones S1 and S2 in the departure detection unit 130 will be described.

Referring to FIG. 5, the wearable electronic device 100 of the present invention determines whether or not the safe areas S1 and S2 are separated using the GPS device 150 that senses a position. The GPS device 150 can sense the current position as a specific coordinate.

In this case, the safe area information S1 and S2 may be information on the location. Specifically, the safe area information (S1, S2) can be set as a range of a space expressed by specific coordinates. More specifically, the safety area information S1 and S2 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. It is possible. For example, if the wearer is a patient accommodated in a nursing hospital, the information on the safety zones S1 and S2 may be information corresponding to a specific space around the accommodated hospital.

The departure detection unit 130 may compare the position coordinates sensed by the GPS device 150 with the safety area information S1 and S2 stored in the memory 110 to determine whether or not the wearable electronic device 100 is detached.

When the departure detection unit 130 determines whether or not the safety zones S1 and S1 are separated based on the position sensed by the GPS device 150, the current position of the wearable electronic device 100 can be relatively accurately grasped There is an advantage that the determination as to whether or not the safety zones S1 and S2 are separated is accurate.

In addition, when the GPS device 150 is used, the safety zone can be formed in various forms. Specifically, the safe area can be specifically set as a range of position coordinates. For example, as in the case of the safety area S1 shown in Fig. 5, the safety area can be formed in a region corresponding to a certain radius from the reference point. Also, as in the safety zone S2 shown in Fig. 5, it is possible to set narrow in one direction and wider in the other direction at the reference point.

However, when the GPS device 150 is used, the power consumed by the GPS device 150 increases the overall power consumption of the wearable electronic device 100 of the present invention. In addition, since the electronic device 100 requires the GPS device 150 to be mounted, there is a disadvantage that the overall size of the electronic device 100 can be increased.

6, the wearable electronic device 100 of the present invention includes a communication unit 160. The departure detection unit 130 determines whether or not the safe area S1 is released through connection of the communication unit 160 . Specifically, the communication unit 160 may be connected to the wireless relay facilities 200a and 200b through wireless communication.

6, it is also possible that the wearable electronic device 100 does not include the GPS device 150. In this case, 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 200a to which the communication unit 160 is connected. Here, the first radio relay facility 200a may be a radio relay facility installed in a facility where the wearer resides.

The coverage of the first radio relay facility 200a can be set to be as close as possible to the safety zone S1 to be set. For this purpose, the connection conditions of the radio relay facility of the communication unit 160 and the output power of the first and second radio relay facilities 200a and 200b can be adjusted. Specifically, the control device of the wearable electronic device 100, the first and second radio relay devices 200a and 200b, and the first and second radio relay devices controls the safety zone S1 to be set by the wearable electronic device 100, The communication unit 160 is connected to the first radio relay facility 200a and the communication unit 160 is connected to the first radio relay facility 200a when the wearable electronic device 100 is out of the set safety zone S1, And can be adjusted to be connected to the second radio relay facility 200b.

To this end, if the electronic device 100 is located within the coverage of the first radio relay facility 200a, it is preferable that the communication unit 160 is connected to the first radio relay facility 200a. The outer portion of the coverage of the first wireless relay facility 200a is preferably the coverage of the second wireless relay facility 200b.

Accordingly, when the communication unit 160 is connected to the first radio relay facility 200a, the departure detection unit 130 determines that the wearable electronic device 100 is in the safe area S1. When the communication unit 160 is disconnected from the first radio relay facility 200a or connected to the second radio relay facility 200b, the detachment detecting unit 130 detects that the wearable electronic device 100 is in the safe area S1 ) Of the user.

In this way, it is advantageous in that power consumption can be relatively reduced by detecting whether or not the GPS unit 150 is disconnected according to the connection state of the radio relay facility of the communication unit 160 without using the GPS unit 150 separately. In addition, the GPS device 150 has an advantage of being able to detect a departure from an indoor space or an underground space in which it is difficult to sense a location. However, there is a disadvantage that it is difficult to perfectly match the safety zone S1 in which the coverage of the first radio relay facility 200a is set. Also, the coverage of the first radio relay facility 200a 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.

7, the wearable electronic device 100 includes both the GPS device 150 and the communication unit 160, and the departure detection unit 130 detects both the GPS device 150 and the communication unit 160 It is possible to judge whether or not the safe area is deviated.

Specifically, the departure detection unit 130 firstly determines whether the safe area S1 is deviated by using the communication unit 160 first. The GPS device 150 can be turned off or can be kept in a standby state consuming only a minimum amount of power until it is first confirmed whether or not the safety zone S1 is detached. If it is confirmed that the safety zone S1 is deviated first, the GPS device 150 is activated to confirm whether or not the safety zone S1 is deviated from the second zone. If it is determined that the primary and secondary safety zones are separated, the departure detection unit 130 determines that the wearable electronic device 100 has deviated from the safety zone S1.

In such a case, the GPS device 150 may not always be activated, and power consumption may be efficiently controlled. Further, after it is confirmed whether or not the first safe area is deviated, the GPS device 150 can be used to check the precise position of the electronic device with coordinates to determine whether the safe area is deviated or not.

Hereinafter, a method of controlling a 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 7 are omitted.

8 is a flowchart illustrating a method of controlling a wearable electronic device according to an embodiment of the present invention. Referring to FIG. 8, a method of controlling a wearable electronic device of the present invention includes storing safety area information and emergency information (S100), determining whether the safe area is detached (S200), and displaying emergency information (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 110 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 110 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.

Step S200 of determining whether or not the safe area is removed is a step of determining whether the wearable electronic device 100 has deviated from the safe area stored in the memory 110. [ The determination as to whether or not the safe area has departed may include a method of determining based on a position sensed by the GPS device 150, a method of determining based on a state that the communication unit 160 is connected to a wireless relay facility, A method of firstly determining based on the state connected to the facility and determining the position based on the position sensed by the GPS device 150 may be used. The above-described respective methods are described above with reference to FIGS. 5 to 7, and the detailed description is omitted.

The step S300 of displaying the emergency information is a step of displaying the emergency information on the display unit 120 when it is determined that the wearable electronic device 100 has deviated from the safe area. 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 140 and the bio-signal measuring unit 140 can measure a bio-signal of the wearer. And the measurement result of the bio-signal can be displayed on the display unit 120. In addition, the measured biometric signal data can be transmitted to the patient management server or the personal portable terminal through the communication unit 160.
