The direction sensor can be a gyroscope, the gravity sensor can be an accelerometer, and the signal receiving unit can be one of a computer, a tablet, a smart phone, or a smart watch.

In order to further understand the features, characteristics and technical content of the present invention, please refer to the following detailed description of the present invention.

Please refer to the first figure, which reveals a diagram of an embodiment of the present invention. The above diagram illustrates the smart barbell training system of the present invention. It includes a barbell 1, and at least one end of the barbell 1 includes an accommodating space; at least one measuring unit 2. It is installed in the accommodating space. The rod body 10 can also have accommodating spaces at both ends and the measuring unit 2 can be installed separately. The measuring unit 2 includes a direction sensor 20, a gravity sensor 21, and a The signal sending element 22 and a power element 23, the direction sensor 20 can be a gyroscope, the gravity sensor 21 can be an accelerometer, the direction sensor 20 and the gravity sensor 21 are electrically connected to the signal sending unit 22, and the direction sensor 20 is such as The gyroscope is used to measure the moving direction of the barbell 1 and generate a first measurement signal. The gravity sensor 21, such as an accelerometer, is used to measure the moving speed of the barbell 1 and generate a second measurement signal, the first measurement signal And the second measurement signal is wirelessly transmitted by the signal sending element 22. The power element 23 is electrically connected to and supplies power to the direction sensor 20, the gravity sensor 21 and the signal sending unit 22. The power element 23 can be additionally connected to a wireless charging unit. Components (not shown), wireless charging components (not shown) are used to charge the power components 23; and

A signal receiving unit 3, which includes a signal receiving element 30 and a display element 31. The signal receiving element 30 receives the first measurement signal and the second measurement signal transmitted by the signal sending element 22 and displays them on the display element 31 . The display element 31 may be a screen. The signal sending element 22 and the signal receiving element 30 can be connected by one of the wireless transmission methods such as infrared, WIFI or Bluetooth.

In the second figure, once the user starts lifting the barbell 1 in the present invention, the direction sensor 20 of the measuring unit 2 starts to measure the moving direction of the barbell 1 and generates the first measurement signal, and the gravity sensor 21 Measure the moving speed of the barbell 1 and generate a second measurement signal. The first measurement signal and the second measurement signal represent the relative change value of the position of the measurement unit 2. The information represented includes the presence or absence of displacement, the direction of displacement, and the amount of displacement. After the first measurement signal and the second measurement signal are wirelessly transmitted by the signal transmitter 22 to the signal receiving unit 3, the signal receiving unit 3 converts each signal into displacement data in a specific format, and calculates it to measure The position of the unit 2 corresponds to a reference point to generate a movement trajectory displayed on the display element 31. The origin of the trajectory can be calculated by the signal receiving unit 3 when the barbell 1 is placed on the ground.

In this way, when the user starts to lift the barbell 1 and performs different stages of action to fully lift the barbell 1, the movement route of the barbell 1 driven by the body movements of the user's whole body, all the movement data can be in the measurement unit 2. The included direction sensor 20 and gravity sensor 21 directly generate measurement data and send them to the signal receiving unit 3 for processing and drawing into a moving track. The signal receiving unit 3 can be one of a computer, a tablet, a smart phone or a smart watch. The movement trajectory can be superimposed with the images taken by other camera devices to provide more comprehensive information for the user's reference.

The direction sensor 20 contained in the measuring unit 2 such as a gyroscope and a gravity sensor 21 such as an accelerometer continuously senses its own displacement, and continuously outputs the first measurement signal and the second measurement signal, and the signal receiving unit 3 according to the preset The sampling frequency is sampled, and time information is added after calculation to generate the displacement record data of the barbell 1, and then use the motion description of one or more reference points in the three-dimensional space to generate a trajectory depicting the three-dimensional space motion. Calculation software and other tools can be used to generate the motion trajectory diagram of the measurement unit 2. Taking the position of the measuring unit 2 as the reference point of the trajectory, a moving picture of the barbell 1 on the display element 31 can be generated.

The moving picture provided by the present invention can more intuitively display the different movement stages and trajectories presented by the barbell 1 due to different body movements during the process of each user starting to lift the barbell 1 to fully lifting the barbell 1. The user can check and improve his own actions by watching the screen displayed on the display element 31 with the movement track of the barbell 1 recorded by the measuring unit 2, and repeat the viewing if necessary. The user can also use wisdom. A mobile phone, a tablet computer or even a smart watch can be used to observe the measurement results nearby. The present invention can provide a more intuitive and efficient training method.
