2, the wearable device 1 according to the embodiment of the present invention includes a watch or band-like device 1a that can be worn on a cuff, or a belt-like device 1b ). ≪ / RTI > However, the present invention is not limited to these embodiments. For example, a band, a watch, a necklace or a bracelet, a pair of glasses, a ring, an earphone, A headset, a clip, a button or the like that can be attached to clothes, shoe, headgear, and the like, all of which are within the scope of the present invention.

On the other hand, in the present specification, the wearable device may be understood as a concept including all of the names of the wearable device, the attachable device, and the wearable device. In the present invention, the wearable device is intended for individual compound sensing. Here, the term " entity " refers mainly to a user (human), but also includes an animal or an object . For example, it is assumed that a thing is located in proximity to a user, or a sporting apparatus that is used by a user in a state of being worn or held. Such exercise equipment includes, but is not limited to, sports rackets, bicycles, kick boards, roller skates, roller blades, skis, skates, snowboards and the like.

Referring to FIG. 3, the wearable device 1 according to the present invention includes a sensing unit 10 and a circuit unit 20.

The sensing unit 10 is an element for sensing biometric information of an object. Herein, the biometric information may be any one of whether or not the individual is active, its degree of impact, its degree, and its horizontality (standing status). That is, the sensing unit 10 may sense the activity of the entity, the amount of activity, the impact, the amount of impact, and the horizontality. In addition, the biometric information may include general biometric information such as pulse rate, oxygen saturation, body temperature, blood pressure, blood sugar, body fat, blood vessel elasticity, and the like.

By acquiring the biometric information of such an object, it is possible to grasp the state more precisely than the state measurement of the object using the surrounding information. For example, it is advantageous to accurately detect the state of an object by directly grasping the activity status of the object by the wearable device, as compared with the case where the activity state of the object is grasped through the video information of the surveillance camera or the like. It becomes possible to more quickly and accurately grasp whether the object is in an emergency situation.

In addition, in the case of direct object-by-object sensing as in the present invention, it is possible to obtain more various state information that could not be obtained by the object state measurement using the conventional surrounding information. For example, it is possible to determine a fall or the like by sensing an acceleration or a jerk in a part of the body, and it is possible to precisely discriminate whether the current user is inactive due to death or accident, .

The risk or emergency situation in the present invention may be a death or an accident of a user, in particular, a fall accident, a fall accident, a burial accident, a fainting, and the like, but it is not limited thereto.

Meanwhile, the sensing unit 10 may be an acceleration sensor. The acceleration sensor processes the output signal to measure dynamic forces such as acceleration, vibration, and shock of the object to be sensed, thereby detecting the motion state of the object. The sensing unit 10 according to an embodiment of the present invention may be an acceleration sensor using any one of an inertial type, a gyro type, an electromagnetic type, and a voltage type. For example, the sensing unit 10 may be a 3-axis or 6-axis gyro sensor, and the type, structure, and shape of the sensor may be selected in consideration of the shape and cost of the wearable device 1, .

Also, the sensing unit 10 may include two or more sensors. 4, the sensing unit 10 may include an acceleration sensor 12. The acceleration sensor 12 may include a first acceleration sensor 12a and a second acceleration sensor 12b.

As described above, when two or more acceleration sensors are disposed apart from each other to sense biometric information of an individual, activity amount or activity state information can be obtained more variously and precisely. For example, by using the relative positional difference between the first and second acceleration sensors 12a and 12b, it is possible to discriminate at least one of whether the object stands up, falls, bends, clouds, tremors, . This is because the algorithm is simple, the burden of the calculation processing is small and the processing time is reduced, but the measurement / discrimination accuracy is at least equal to or higher than the case of determining whether the object is standing up or tumbled by using one acceleration sensor.

5 is a view showing the state of the wearable device 1 at the first time point a, the second time point b and the third time point c using the first and second acceleration sensors 12a and 12b spaced apart from each other. Position state. As shown, using the positional relationship of the first and second acceleration sensors 12a and 12b at a specific point in time, and using the velocity, acceleration, or jerk information together with this information, It is possible to accurately and quickly determine whether the user has fallen, whether the user is bent, or whether the user is rolling.

5 (a) shows the standing state of the user, FIG. 5 (c) shows the state in which the user is lying, for example. In such a lying state, the residual vibration (residual vibration) If it is sensed, it can be determined that the user is in the current seizure state. In this case, it is possible to promptly transmit the alarm signal to an external monitor / manager, a medical person, or a guardian designated in advance through the communication unit 22 described later.

Through this, it is possible to detect whether the wearer (user) is currently collapsed, an external shock, or no movement for a predetermined time or longer, and through this, it is possible to read whether an accident or death has occurred. Such measurements are also applicable to animals (including pets) for experimentation or protection, or various things (including dangerous goods) that require movement or movement information to be measured.

The alarm unit 22 is electrically connected to the control unit 21 and outputs an alarm signal to the wearer. That is, the alarm unit 22 can output an alarm signal through vibration, sound, or light emission signal.
