FIG. 3 is a schematic diagram of calculation of a moving trajectory.

Please refer to FIG. 1. FIG. 1 is a schematic diagram showing the architecture of the wearable device 100 of the present invention. The wearable device 100 includes an electronic compass 110, a central processing unit 120, an acceleration sensor 130, and a display screen 140. The wearable device 100 is, for example, an electronic device in which an electronic watch or an electronic bracelet can be worn on a wrist, and has a waterproof function. The electronic compass 110 and the acceleration sensor 130 are connected to the central processing unit 120, respectively. The electronic compass 110 is a three-dimensional magnetic sensor capable of sensing the magnetic fields in the three directions of the earth X, Y, and Z, further judging the direction of the north, and using the north as a reference direction for judgment, and another one is fixed to wear. The reference direction on the device 100 is compared with the reference direction, and the absolute moving angle of the wearable device 100 can be calculated. Therefore, the electronic compass 110 can sense the moving angle or moving direction of the wearable device 100, and the information sensed by the electronic compass 110. It is the first mobile information 111. The electronic compass 110 transmits the first mobile information 111 to the central processing unit 120. The acceleration sensor 130 is a gravity sensor, also referred to as a G-sensor, and the acceleration sensor 130 can sense the acceleration changes of the wearable device 100 in three directions of X, Y, and Z, and analyze X, Y, The movement angle or the moving direction of the wearable device 100 can be determined by the acceleration change of the three directions, and the information sensed by the acceleration sensor 130 is the second movement information 131. The acceleration sensor 130 transmits the second movement information 131 to the central processing unit 120. The central processing unit 120 can receive the first movement information 111 of the electronic compass 110 and the second movement information 131 of the acceleration sensor 130, and calculate the first movement information 111 and the second movement information 131 to analyze the state of the swimming, and finally calculate The result is displayed on the display screen 140.

Please refer to FIG. 2, which illustrates the steps of the central processor analyzing the swimming. First, a wearable device 100 is provided and worn by a wearer and starts swimming (step S01). Thereafter, the central processing unit 120 reads the second movement information 131 of the acceleration sensor 130 (step S02). After that, the central processing unit 120 determines whether the wearable device 100 is in an idle state (step S03), and the central processing unit 120 reads the second movement information 131 of the acceleration sensor 130, if the second mobile information 131 remains horizontal. When the moving direction exceeds a certain time, the central processor determines that the wearable device 100 is idle. In other words, the wearable device 100 moves in the horizontal direction for more than a predetermined time, indicating that the wearer is floating on the water surface and does not perform the stroke operation; otherwise, the wearable device 100 does not move in the horizontal direction for more than a predetermined time, indicating that the wearer is worn. The person is paddling.

If the determination in step S03 is "NO", it means that the wearable device 100 is not in an idle state, and the central processing unit 120 determines that the wearer is drawing water. At this time, the central processing unit 120 reads the second movement information 131 of the acceleration sensor 130 and determines the swimming posture (step S04). If the second movement information 131 is the horizontal movement direction, the central processing unit 120 determines the swimming posture. If the second movement information 131 is moving in the vertical direction, the central processing unit 120 determines that the swimming posture is free. After the swimming posture judgment is completed, the central processing unit 120 reads the first movement information 111 of the electronic compass 110 to calculate the number of strokes of the wearer (step S05), and the central processing unit 120 records the first movement at each time point. The information 111 is compared and analyzed to analyze the adjacent first movement information 111 to calculate a movement trajectory. When the movement trajectory presents a ring shape, the central processing unit 120 determines that the wearer strokes the water once, and can plan the water. frequency. Since the human being is swimming, whether it is a frog or a freestyle, the palm (the part with the wearable device 100) is padd in a repeated circle, so that when the movement track assumes a ring shape, the stroke can be determined once. . In addition, when the wearer swims freely, the palm is mostly drawn in the vertical direction, so when the second movement information 131 is in the vertical movement direction, the wearable device 100 judges to be free-style; and the wearer uses the frog type When swimming, the palm is mostly padded in the horizontal direction. Therefore, when the second movement information 131 is in the horizontal movement direction, the wearable device 100 determines that it is free.

Please refer to FIG. 3 , which is a schematic diagram of calculation of a moving trajectory. For example, the central processing unit 120 records the first movement information 111 every second, T=1 indicates the state of the electronic compass 110 at the first second, and the arrow N is the north direction determined by the electronic compass 110, that is, the reference direction; F is the reference direction fixed to the wearable device 100. Since the arrow N is always directed to the north, the correct movement direction of the wearable device 100 can be judged by comparing the arrow N with the arrow F. For example, when T=1, the wearable device 100 moves to the northeast. The central processing unit 120 records the movement angle of each time point from T=1 to T=10, and connects the arrow F of each time point in series to calculate the movement trajectory of the wearable device 100. As shown in FIG. 3, the moving track presents a ring shape, and the central processing unit 120 can determine the water stroke once. In addition, the order of the above steps S04, S05 and S06 in FIG. 2 is a preferred embodiment of the present invention, but is not limited thereto, and those skilled in the art should know that the order of steps S04, S05 and S06 is Any change.

In step S03, if the result of the determination by the wearable device 100 is "YES", it means that the wearable device 100 is in an idle state, that is, the wearer does not perform the stroke operation. At this time, the central processing unit 120 reads the first movement information 111 of the electronic compass 110, determines whether the wearer has turned back (step S06), and the central processing unit 120 records the first movement information 111 of the electronic compass 110, and calculates The average moving direction of the wearable device 100 is to determine the swim direction of the wearer, and the average moving direction is stored in the central processing unit 120. In step S06, the central processing unit 120 compares the average moving direction with the average moving direction when the previous idle state is obtained. If the comparison result finds that the average moving direction is reversed, it is determined that the wearable device 100 has been folded back, and the wearer can be counted back. The number of times. When the swimmer swims in the pool, when he swims to the edge of the pool to turn back, most swimmers kick the edge of the pool with their feet and push the body forward, and the hands will straight forward. And let the body float horizontally for a period of time, and start to draw water when the floating speed slows down. Therefore, the wearable device 100 judges to be idle while maintaining the horizontal movement, and compares whether the average moving direction is reversed to determine the number of foldbacks.

In addition, the wearer can input the length of the swimming pool from the wearable device 100 to the central processing unit 120 (step S07), the central processing unit 120 calculates the number of reversals of swimming (step S08), and calculates the swimming distance between the number of reentry and the length of the swimming pool ( Step S09), the calculation formula is illustrated as follows:

Swimming distance = swimming pool length × (number of turns + 1)

In addition, the wearer can also input weight to the central processor 120 from the wearable device 100. The central processing unit 120 can calculate the amount of heat consumption according to the swimming time and the wearer's weight (step S10), and the calculation formula is as follows:

Calorie consumption = wearer weight × time (hours) × 6 (frog type)

Wearer weight × time (hours) × 8 (freestyle)

In the above calorific value calculation formula, the coefficients 6 and 8 are based on the average value of the calories consumed by the average adult during exercise, but the actual value can still be set, changed or factory-set in the wearable device 100 according to various conditions. Man-made changes.

When the central processing unit 120 calculates the data of the swimming distance, the number of reversing times, the swimming posture, the number of water strokes, and the amount of heat consumption, the data is displayed on the display screen 140 (step S11), and the wearer can select the data. display. The data can also be transmitted via wired or wireless transmission to an APP or cloud platform on other electronic devices, such as a personal computer, a tablet or a smart phone. The wearer can count the results of each swim and further adjust the time and intensity of swimming.

The wearable device 100 of the present invention is provided with a function of analyzing swimming, and a person who loves swimming needs to wear the wearable device 100 to input the length of the swimming pool and the weight of the user. While swimming, the wearable device 100 can analyze the state of the swim and display various types of data on the wearable device 100, so that the wearer can immediately observe the state of the swim. The data can be assisted by other electronic devices to help the wearer understand the results and statistical changes of each swim, and to accurately control the goals of each swim.
