The driving device of the wrist-mounted electronic device may be provided in the wrist-mounted electronic device.

The driving condition is that the state in which the gravitational acceleration of the wrist-mounted electronic device is positioned within a specific range continues for a specific time, and at the same time, the pure acceleration (the acceleration obtained by removing the gravitational acceleration from the acceleration of the wrist- Indicates that the state lasts for a certain time. A detailed description thereof will be described later.

There are three types of embodiments of the wrist-mounted electronic device according to the present invention.

Each embodiment will be described with reference to FIGS. 1, 2, and 3. FIG.

1 is a block diagram of a drive device for a wrist-mounted electronic device according to a first embodiment of the present invention.

Referring to FIG. 1, a driving apparatus 10 for a wrist-mounted electronic device according to a first embodiment of the present invention includes a power supply unit 1 and a driving unit 2. [ The driving device 10 of the wrist-mounted electronic device shown in Fig. 1 may be provided in a wrist-mounted electronic device (not shown), and the driving device 10 of the wrist- (Which is the acceleration obtained by removing the gravitational acceleration from the acceleration of the wrist electronic device) is included (sustained) for each time set in the set range, respectively.

The power supply unit 1 supplies power necessary for driving the wrist-mounted electronic apparatus, and the wrist-mounted electronic apparatus is attached to the user's wrist so that the user can freely move the wrist- But may be a battery that is not in the form of a Switching Mode Power Supply (SMPS). The battery may be a rechargeable secondary battery. To this end, the power supply unit 1 may include a charging unit capable of charging the secondary battery.

The driving unit 2 calculates the three-axis gravitational acceleration gx, gy, gz and the three-axis pure acceleration RAx, RAy, RAz included in the three-axis acceleration x ', y', z ' , And the states included in the respective ranges are maintained for the set time, the power supply unit 1 is controlled to apply power to the wrist electronic apparatus to drive the wrist electronic apparatus.

The driving unit 2 includes an acceleration sensor 3, a gravity acceleration extraction unit 4, a pure acceleration extraction unit 5, a determination unit 6, and a drive control unit 7.

The acceleration sensor 3 measures the three-axis acceleration (x ', y', z ') according to the motion of the wrist-mounted electronic device as the user performs the motion, for example,

The gravitational acceleration extraction section 4 extracts the triaxial gravitational acceleration gx, gy, gz from the three-axis acceleration x ', y', z '. That is, the gravitational acceleration extraction unit 4 extracts the triaxial gravitational acceleration gx, gy, gz by filtering the three-axis acceleration x ', y', z '. In this case, the triaxial gravitational acceleration gx, gy, and gz may be triaxial gravitational acceleration in inverse proportion to the altitude squared value varying with the position of the user's hand.

의 관계를 가지게 된다. At this time, according to the second law of Newton, the rate of change per unit time of an object having a mass m, that is, the acceleration a, has a value proportional to a force F acting on an object having a mass m. In other words

.

의 관계를 가지게 되며, 비례상수 G는 만유인력 상수 또는 중력상수라고도 한다. Newton's law of gravitational attraction represents the force acting between two objects with mass, and the force (F) acting between the two objects is proportional to the product of the masses m and m ' The inverse of the square of the distance r between the particle points. In other words,

And the proportional constant G is also called a gravitational attraction constant or gravity constant.

의 관계를 가지며, 고도 h=0인 지표면에서

의 값을 가지며 고도 h가 높아질수록 작아진다. 즉 3차원 좌표에서 평면(고도 h=0), 중력과 수직을 이루는 x축과 y축에서의 중력가속도는

이며 중력과 수평을 이루는 z축에서의 중력가속도는 높이(고도)에 따라 달라진다. 다시 말해서 사용자가 고도가 높은 지역으로 움직이는 경우, 처음 고도가 0인 지역에서 고도가 높은 지역으로 움직이기 시작했을 때 사용자는 가장 많은 힘을 필요로 하여 많은 칼로리를 소비하고 고도가 높아질수록 힘을 적게 필요로 하며, 이 관계는

로 나타내며, 이 관계로부터 중력가속도를 구하면 사용자의 움직임에 따라 변하는 고도를 구할 수 있게 된다. The acceleration generated under the influence of gravity, as in the case of an object falling on the surface of the earth, is called gravitational acceleration. Therefore, considering Newton's second law and Newton's law of gravitational pull, the force F acting between the earth's surface and the mass M of the earth at a certain distance, that is, the object m at the altitude h and the radius R, Finally, gravity

. From this,

The

, And at the altitude h = 0 on the ground surface

, And decreases as the altitude h increases. That is, the plane (altitude h = 0) in three-dimensional coordinates, gravitational acceleration in the x-axis and y-axis perpendicular to gravity

And the gravitational acceleration in the z-axis, which is horizontal to gravity, depends on the height (altitude). In other words, when a user moves to a high altitude area, when the altitude starts to move from a high altitude area to a high altitude area, the user needs the most power and consumes a lot of calories. And this relationship is

When the gravitational acceleration is obtained from this relationship, an altitude varying with the movement of the user can be obtained.

를 구해야 하는데, 중력가속도는 사용자의 움직임에 따라 가속도 센서의 중력가속도에 대한 방향이 계속 변하게 된다. 따라서 이를 보정해줄 필요가 있다. 이를 위해서 중력가속도 추출부(4)는 가속도 센서(3)에 의해 일정 횟수, 예를 들어 99회 측정된 3축 가속도(x', y', z')들을 평균하여 3축의 중력가속도(gx, gy, gz)를 추출할 수 있다. 이는 가속도 센서(4)에 의해서 측정되는 3축 가속도(x', y', z')가 사용자의 움직임에 따라 계속 변하게 되지만 연속적으로 검출되는 이들 값들을 평균하면 결국 중력가속도의 방향이 된다는 것에 기초한다. Accordingly,

The direction of the gravity acceleration of the acceleration sensor continuously changes according to the movement of the user. Therefore, it is necessary to correct this. For this purpose, the gravitational acceleration extraction unit 4 averages the three-axis acceleration x ', y', z 'measured a predetermined number of times, for example, 99 times by the acceleration sensor 3, gy, gz) can be extracted.
