A lighting unit may be installed outside the electronic weight pin 100. When it is determined from the signal sensed by the fourth sensor 40 that the electronic weight pin 100 is in a horizontal state, the lighting unit emits light so that the user can confirm that the electronic weight pin is in a horizontal state. The signals measured by the (20) to fourth sensors (40) are transmitted to the control unit (70).

The control unit 70 identifies the type of the weight machine through the second sensor 20, calculates the mass of the fixed weight block through signals measured by the first sensor 10 and the fourth sensor 40, The user's exercise amount may be calculated through the third sensor 30.

Thereafter, after the user inserts the electronic weight pin 100 into the pin ball of the weight block to which he/she wants to exercise, and presses the button 50 once for a long time, the current position, which is the second position, is set by the controller 70. , The height at this time (the height of the second position) is measured by the first sensor 10.

The controller 70 may calculate the height of the fixed weight block by using the difference between the height of the first position and the height of the second position, and calculate the mass of the fixed weight block from the height of the weight block. Preferably, after the user presses the button 50, after confirming that the lighting part is turned on from the signal sensed by the fourth sensor 40, the electronic weight pin is in a horizontal state, the first position and the second position can be set. .

For example, assuming that the height of each weight block provided in the identified weight machine is 10 cm and the mass of each weight block is 5 kg, the height of the first position is 1 meter and the height of the second position is 70 cm, Since there are 6 fixed weight blocks, the mass is 30kg.

As another example, the main body 1 may be provided with two buttons 50 (a first button 50 and a second button 50). In this case, when the user presses the first button 50, the first position may be set, and when the user presses the second button 50, the second position may be set.

The management server 200 transmits the user's exercise amount information converted into a database to the user terminal 300, and the user can search for an exercise direction from the user's exercise information.

Alternatively, the height and/or mass of the weight block may be set through an application program mounted on the user terminal 300. Since the height and mass of each weight block may be different according to the specifications of the weight machine, the height and mass of the weight block may be changed and set in the user terminal 300. For example, the height and mass of the weight block can be changed from 3 csm and 5 kg to 1.5 cm and 3 kg.

Hereinafter, the operation of the electronic weight pin according to the embodiment of the present invention as described above will be described in detail.

First, when a user tags an electronic weight pin on a weight machine, the electronic weight pin and the weight machine perform RF communication, and the type of the weight machine is transmitted to the electronic weight pin.

After the user inserts the electronic weight pin into the uppermost or lowermost weight block among a plurality of weight blocks provided in the weight machine, and presses the button once, the controller 70 sets the position at this time as the first position, and the first The height of the current position (the height of the first position) is measured by the sensor 10, and the measured position is stored in the controller 70.

And when the user inserts the electronic weight pin into the desired weight block and presses the button once for a long time, the controller 70 sets the position at this time to the second position, and the height of the current position by the first sensor 10 The (height of the second position) is measured, and the measured position is stored in the control unit 70.

The control unit calculates the mass of the fixed weight block that the user wants to exercise from the difference between the height of the first position and the height of the second position, the height of each weight block, and the mass of each weight block. Since the method of calculating the mass of the fixed weight block is the same as described above, a detailed description will be omitted.

Thereafter, when the user performs an exercise, the controller 70 calculates the user's exercise amount from the mass of the fixed weight block and the speed or acceleration measured from the third sensor, and manages the user's exercise amount under the database. .

If necessary, a series of operations performed by the control unit 70 may be performed by the management server 200. In this case, the management server 200 may convert a database and transmit the managed user's exercise history to the user terminal 300 carried by the user. The user may manage his or her own exercise amount by referring to his or her exercise amount transmitted through the management server 200.
