Description

Technical Field

[0001] The present invention relates to the technical field of fitness equipment accessories, and in particular to a Bluetooth counter for a tensioner and a counting method. Background Art

[0002] As people's health awareness continues to improve, more and more people begin to exercise. my country's sporting goods industry is developing rapidly. In order to improve people's sports awareness, fitness equipment that assists exercise is becoming more and more diverse. A single exercise method can easily make people feel boring. Therefore, a device that can intuitively view the amount of exercise is needed to stimulate the user's interest in sports to a certain extent.

[0003] Fitness pullers are used to train the muscles of the arms and chest. Systematic training often requires multiple sets of training, and each set requires several rounds of training. Counting is also required during the stretching process, which can easily cause confusion and also brings many inconveniences to training. Summary of the invention

[0004] The present invention provides a Bluetooth counter for a puller and a counting method, which have a simple structure and a reasonable design, can be used for intelligent counting during pulling exercises, and does not require counting by oneself, and is suitable for application and promotion.

[0005] On the one hand, the present invention provides a Bluetooth counter for a tensioner, characterized in that it includes a Bluetooth device, a magnet, a rotating wheel, a first reed switch and a second reed switch, the first reed switch and the second reed switch are both connected to the Bluetooth device, the magnet is installed on the rotating wheel, the rotating wheel is movably installed on the rotating seat of the tensioner, the rotating wheel rotates around the rotating seat under the action of an external force, and the connecting rope of the tensioner is wound around the rotating wheel; because the connecting rope is wound around the rotating wheel, the rotating wheel will follow the rotation when the rope is pulled or sent during use, and during the rotation of the rotating wheel, the relative distance between the magnet and the first reed switch and the second reed switch will change, and the first reed switch and The second reed switch is a magnetic switch element. The switch is closed when the magnetic field approaches and is opened when the magnetic field leaves. Since the rotation directions of the rotating wheel are opposite in the rope pulling and rope sending states, two magnetic switch elements, the first reed switch and the second reed switch, are arranged and the magnetic field formed by the rotating magnet is used to produce different signal parameters of the first reed switch and the second reed switch obtained by the Bluetooth device when the rotating wheel rotates forward and reverse, thereby determining whether the user is pulling the rope or sending the rope. Since one rope pulling and one rope sending constitute one stretching action, the Bluetooth device can count and output the number of stretching times of the tensioner by recording the number of rope sending or rope pulling.

[0006] The device may also include an LCD display. The Bluetooth device controls the LCD driver chip in a bus control manner through the three ports P00\P01\P34, thereby driving the LCD to display the exercise time, speed, number of times, mileage, calories and heart rate values. The LCD display can be directly installed on the counter without having to be viewed through mobile phones or other communication devices.

[0007] Optionally, the Bluetooth device includes a mounting block, a Bluetooth chip and a sensing chip, the Bluetooth chip and the sensing chip are fixed to the tensioner through the mounting block, the sensing chip communicates with the Bluetooth chip, and the sensing chip is used to sense voltage changes of the Bluetooth chip interface to determine the state of movement.

[0008] Optionally, one end of the first reed switch and the second reed switch are connected to the Bluetooth chip through wiring, and the other ends of the first reed switch and the second reed switch are connected to a power supply; the interface on the Bluetooth chip connected to the first reed switch is a P16 interface, and the interface on the Bluetooth chip connected to the second reed switch is a P17 interface. The interface on the Bluetooth chip connected to the first reed switch and the second reed switch always maintains a high voltage of approximately 3V. After the first reed switch or the second reed switch is in a closed state after the magnetic field of the magnet approaches, the interface on the Bluetooth chip connected to the first reed switch and the second reed switch will be connected to the ground and pull down the port voltage to approximately 0V. The sensing chip determines the state of exercise by sensing the voltage change of the interface; a HEART interface can also be provided on the Bluetooth device, which is a hand-held, ear-clip, hand-clip or wireless heart rate detector interface for testing the user's heart rate value.

[0009] Optionally, resistors are provided on the wiring between the first reed switch, the second reed switch and the Bluetooth chip; the resistor is a 4.7kΩ pull-down resistor. When the first reed switch is connected to the ground, the resistor between the first reed switch and the Bluetooth chip can prevent the interface connecting the Bluetooth chip and the first reed switch from being directly connected to the ground. When the second reed switch is connected to the ground when the magnetic field is close, the resistor between the second reed switch and the Bluetooth chip can prevent the interface connecting the Bluetooth chip and the second reed switch from being directly connected to the ground.

[0010] Optionally, a first capacitor is connected between the wiring connecting the first reed switch to the Bluetooth chip and the wiring connecting the first reed switch to the power supply, and a second capacitor is connected between the wiring connecting the second reed switch to the Bluetooth chip and the wiring connecting the second reed switch to the power supply; the first capacitor and the second capacitor are both 0.47μf filter capacitors, and when the first reed switch and the second reed switch perform switching actions while the magnetic field changes, the first capacitor and the second capacitor can effectively prevent the first reed switch and the second reed switch from malfunctioning due to small fluctuations in the magnetic field.

[0011] Optionally, it also includes a communication device, which is connected to the Bluetooth device for communication. The communication device is a mobile phone or a computer. Each Bluetooth device has a corresponding exclusive device number. When multiple counters are placed together, the communication device will automatically identify the nearest counter and display the device number, automatically search and manually click to connect, so as to achieve the connection between the communication device and the Bluetooth device. When the communication device leaves the effective Bluetooth distance, it will automatically prompt that the connection is disconnected.

[0012] The counting method using the above-mentioned Bluetooth counter for a tensioner is characterized by comprising the following steps:

[0013] Preparation:

[0014] When the athlete pulls or sends the rope, the rotating wheel is driven to rotate, and the rotating wheel drives the magnet to move synchronously. The speed ratio of the rotating wheel and the magnet is 1:1;

[0015] The first reed switch and the second reed switch are in a short-circuit state when the magnetic field of the magnetic steel approaches, and the first reed switch and the second reed switch are in an open-circuit state when the magnetic field of the magnetic steel moves away. The short-circuit state signal recognized by the Bluetooth device is recorded as 0, and the open-circuit state signal recognized by the Bluetooth device is recorded as 1; the first reed switch and the second reed switch are magnetic switch elements. When the magnetic field of the magnetic steel approaches, the switch is closed, and when the magnetic field leaves, the switch is opened, which will present a short-circuit or open-circuit state, so that the Bluetooth device can recognize it. In the short-circuit state, the interface position of the first reed switch or the second reed switch and the Bluetooth device is connected to the ground and the port voltage is pulled down to 0V.

[0016] Determination of the pull rope signal:

[0017] When the athlete pulls the rope, the connecting rope drives the rotating wheel to rotate, and the magnet on the rotating wheel moves one circle. The rope pulling signal recognized by the Bluetooth device is a complete signal of 1-0-0-1-1 to the first reed switch, and the signal recognized by the Bluetooth device to the second reed switch is 1-1-0-0-1 respectively;

[0018] When the rotating wheel rotates multiple times, the Bluetooth device recognizes that the signals of the first reed switch and the second reed switch are repeated according to the rule of the first circle;

[0019] Determination of the rope sending signal:

[0020] When the athlete sends the rope, the connecting rope drives the rotating wheel to rotate. The magnet on the rotating wheel moves one circle driven by the rotating wheel. The Bluetooth device recognizes the complete signal of the first reed switch as 1-1-0-0-1, and the Bluetooth device recognizes the complete signal of the second reed switch as 1-0-0-1-1. The Bluetooth chip and the sensor chip in the Bluetooth device recognize the signals of the first reed switch and the second reed switch to determine whether the user is pulling the rope or sending the rope.

[0021] When the rotating wheel rotates multiple times, the Bluetooth device recognizes that the signals of the first reed switch and the second reed switch are repeated according to the rule of the first circle;

[0022] Using the principle of analog encoder, the sensing chip identifies and processes the different signals of the first reed switch and the second reed switch through the Bluetooth chip, and can determine the rope pulling or rope sending status. Since the rotating wheel rotates multiple times each time the rope is pulled or sent, the number of rotations of the rotating wheel can be determined based on the number of times the signal cycle occurs.

[0023] Calculation of pull times and length:

[0024] Each time the Bluetooth device obtains a rope-pulling signal and a rope-sending signal, the number of pulls increases by one; using the above-mentioned analog encoder principle, rope-pulling and rope-sending can be accurately judged. Each rope-pulling and rope-sending is a motion signal. After each motion signal is generated, the count increases by one. Usually, rope-pulling is not counted, but rope-sending is counted by one, which can avoid over-counting and missed counting.

[0025] The number of repetitions of the rope pulling signals of the first reed switch and the second reed switch obtained by pulling the Bluetooth device when pulling the rope is converted into the number of revolutions of the rotating wheel, and the total pulling length is calculated by the number of revolutions*the circumference of the rotating wheel.

[0026] Optionally, in the step of determining the pull rope signal:

[0027] When the connecting rope returns to the shortest state, the magnet stays between the first reed switch and the second reed switch. When the athlete pulls the rope, the rotating wheel drives the magnet to move one circle from the direction away from the first reed switch to the direction close to the first reed switch. The complete signal recognized by the Bluetooth device for the first reed switch is 0-1-1-1-0-0-1-1, and the complete signal recognized by the Bluetooth device for the second reed switch is 0-0-1-1-1-0-0-1.

[0028] When the rotating wheel rotates multiple times, the Bluetooth device recognizes that the signals of the first reed switch and the second reed switch are repeated according to the rule of the first circle;

[0029] Optionally, in the step of determining the rope sending signal:

[0030] When the connecting rope returns to the shortest state, the magnet stays between the first reed switch and the second reed switch. When the athlete sends the rope, the magnet moves from the direction away from the second reed switch to the direction close to the second reed switch. The signal recognized by the Bluetooth device for the first reed switch is 0-0-1-1-1-0-0-1, and the signal recognized by the Bluetooth device for the second reed switch is 0-1-1-1-0-0-1-1 respectively.

[0031] When the rotating wheel rotates multiple times, the Bluetooth device recognizes that the signals of the first reed switch and the second reed switch are repeated according to the rule of the first circle.

[0032] Optionally, in the step of calculating the number and length of pulls:

[0033] The Bluetooth device uploads the rope pulling signal and rope sending signal to the communication device, and the communication device calculates and displays the number of pulls and the length. Each Bluetooth device has a corresponding exclusive device number. When multiple counters are placed together, the communication device will automatically identify the nearest counter and display the device number, automatically search and manually click to connect, to achieve the connection between the communication device and the Bluetooth device. When the communication device leaves the effective distance of Bluetooth, it will automatically prompt that the connection is disconnected. After one minute of movement stops, the Bluetooth device automatically enters the power-saving and low-power sleep mode. In the power-saving and low-power sleep mode, the APP of the communication device cannot search for the Bluetooth device. In the power-saving and low-power sleep mode, the Bluetooth device can be awakened by a motion signal consisting of a rope pulling signal and a rope sending signal. After awakening, the Bluetooth device can be searched through the mobile phone or computer APP. To be on the safe side, 2-3 motion signals can also be used to awaken.

[0034] Based on the above, since the connecting rope is wrapped around the rotating wheel, the rotating wheel will rotate with it when the rope is pulled or sent during use. During the rotation of the rotating wheel, the relative distance between the magnet and the first reed switch and the second reed switch will change. The first reed switch and the second reed switch are magnetic switch elements. The switch is closed when the magnetic field approaches and the switch is disconnected when the magnetic field leaves. Since the rotation directions of the rotating wheel are opposite in the rope pulling and rope sending states, the magnetic field formed by the first reed switch and the second reed switch and the rotating magnet is set to produce different signal parameters of the first reed switch and the second reed switch obtained by the Bluetooth device when the rotating wheel rotates forward and reverse, thereby judging whether the user is pulling the rope or sending the rope. Since one rope pulling and one rope sending constitute one stretching action, the Bluetooth device can count and output the number of stretching times of the tensioner by recording the number of rope sending or pulling.

[0035] The invention has a simple structure and a reasonable design, can be used for intelligent counting during zipping, does not require self-counting, is suitable for application and promotion, and the result error obtained by adopting the counting method is small.

[0052] like Figures 1 to 9 As shown, a Bluetooth counter for a tensioner of the present invention comprises a Bluetooth device 7, a magnetic steel 2, a rotating wheel 3, a first reed switch 4000 and a second reed switch 5000. The first reed switch 4000 and the second reed switch 5000 are both connected to the Bluetooth device 7. The magnetic steel 2 is mounted on the rotating wheel 3. The rotating wheel 3 is movably mounted on the rotating seat of the tensioner 1. The rotating wheel 3 rotates around the rotating seat under the action of an external force. The connecting rope of the tensioner 1 is wound around the rotating wheel 3. Since the connecting rope is wound around the rotating wheel 3, the rotating wheel 3 will rotate with the pulling or feeding of the rope during use. During the rotation of the rotating wheel 3, the relative distance between the magnetic steel 2 and the first reed switch 4000 and the second reed switch 5000 will change. The first reed switch 4 000 and the second reed switch 5000 are magnetic switch elements. The switch is closed when the magnetic field approaches and is opened when the magnetic field leaves. Since the rotation directions of the rotating wheel 3 are opposite in the rope pulling and rope sending states, the two magnetic switch elements, the first reed switch 4000 and the second reed switch 5000, and the magnetic field formed by the rotating magnet 2 are set to produce different signal parameters of the first reed switch 4000 and the second reed switch 5000 obtained by the Bluetooth device 7 when the rotating wheel 3 rotates forward and reverse, thereby judging whether the user is pulling the rope or sending the rope. Since one rope pulling and one rope sending constitute one stretching action, the Bluetooth device 7 can count and output the number of stretching times of the tensioner 1 by recording the number of rope sending or rope pulling.

[0053] The device may also include an LCD display 1400. The Bluetooth device 7 controls the LCD driver chip in a bus control manner through the three ports P00\P01\P34, thereby driving the LCD to display the exercise time, speed, number of times, mileage, calories and heart rate values. The LCD display 1400 can be directly installed on the counter without having to be viewed through a mobile phone or other communication device.

[0054] The Bluetooth device 7 includes a mounting block 9, a Bluetooth chip 8000 and a sensing chip. The Bluetooth chip 8000 and the sensing chip are fixed on the tensioner 1 through the mounting block 9. The sensing chip communicates with the Bluetooth chip 8000. The sensing chip is used to sense the voltage change of the Bluetooth chip 8000 interface to determine the state of movement.

[0055] One end of the first reed switch 4000 and the second reed switch 5000 are connected to the Bluetooth chip 8000 through wiring, and the other ends of the first reed switch 4000 and the second reed switch 5000 are connected to the power supply; the interface on the Bluetooth chip 8000 connected to the first reed switch 4000 is a P16 interface, and the interface connected to the second reed switch 5000 is a P17 interface. The interface connecting the Bluetooth chip 8000 with the first reed switch 4000 and the second reed switch 5000 always maintains a high voltage of about 3V. In the closed state, after the first reed switch 4000 or the second reed switch 5000 is in the closed state after the magnetic field of the magnet 2 approaches, the interface on the Bluetooth chip 8000 connected to the first reed switch 4000 and the second reed switch 5000 will be connected to the ground and pull down the port voltage to about 0V, and the sensing chip determines the state of movement by sensing the voltage change of the interface; a HEART interface can also be provided on the Bluetooth device, which is a hand-held, ear-clip, hand-clip or wireless heart rate detector interface for testing the user's heart rate value.

[0056] Resistors 1001 are provided on the wiring between the first reed switch 4000, the second reed switch 5000 and the Bluetooth chip 8000; the resistor 1001 is a 4.7kΩ pull-down resistor 1001. When the first reed switch 4000 is connected to the ground, the resistor 1001 between the first reed switch 4000 and the Bluetooth chip 8000 can prevent the interface connecting the Bluetooth chip 8000 and the first reed switch 4000 from being directly connected to the ground. When the second reed switch 5000 is connected to the ground when the magnetic field approaches, the resistor 1001 between the second reed switch 5000 and the Bluetooth chip 8000 can prevent the interface connecting the Bluetooth chip 8000 and the second reed switch 5000 from being directly connected to the ground.

[0057] A first capacitor 1100 is connected between the wiring connecting the first reed switch 4000 and the Bluetooth chip 8000 and the wiring connecting the first reed switch 4000 and the power supply, and a second capacitor 1200 is connected between the wiring connecting the second reed switch 5000 and the Bluetooth chip 8000 and the wiring connecting the second reed switch 5000 and the power supply; the first capacitor 1100 and the second capacitor 1200 are both 0.47μf filter capacitors, and when the first reed switch 4000 and the second reed switch 5000 perform switching actions while the magnetic field changes, the first capacitor 1100 and the second capacitor 1200 can effectively prevent the first reed switch 4000 and the second reed switch 5000 from malfunctioning due to small fluctuations in the magnetic field.

[0058] It also includes a communication device, which is connected to the Bluetooth device 7 for communication. The communication device is a mobile phone or a computer. Each Bluetooth device 7 has a corresponding exclusive device number. When multiple counters are placed together, the communication device will automatically identify the nearest counter and display the device number, automatically search and manually click to connect, so as to achieve the connection between the communication device and the Bluetooth device 7. When the communication device leaves the effective Bluetooth distance, it will automatically prompt that the connection is disconnected.

[0059] The counting method using the above-mentioned Bluetooth counter for a tensioner includes the following steps:

[0060] Preparation:

[0061] When the athlete pulls or sends the rope, the rotating wheel 3 is driven to rotate, and the rotating wheel 3 drives the magnetic steel 2 to move synchronously. The speed ratio of the rotating wheel 3 and the magnetic steel 2 is 1:1;

[0062] The first reed switch 4000 and the second reed switch 5000 are in a short-circuit state when the magnetic field of the magnet 2 approaches, and are in an open-circuit state when the magnetic field of the magnet 2 moves away. The short-circuit state signal recognized by the Bluetooth device 7 is recorded as 0, and the open-circuit state signal recognized by the Bluetooth device 7 is recorded as 1; the first reed switch 4000 and the second reed switch 5000 are magnetic switch elements. When the magnetic field of the magnet 2 approaches, the switch is closed, and when the magnetic field leaves, the switch is opened, which will present a short-circuit or open-circuit state, so that the Bluetooth device 7 can recognize that in the short-circuit state, the interface position of the first reed switch 4000 or the second reed switch 5000 and the Bluetooth device 7 is connected to the ground and the port voltage is pulled down to 0V.

[0063] Determination of the pull rope signal:

[0064] When the athlete pulls the rope, the connecting rope drives the rotating wheel 3 to rotate, and the magnet 2 on the rotating wheel 3 moves one circle. The rope pulling signal recognized by the Bluetooth device 7 is a complete signal of 1-0-0-1-1 to the first reed switch 4000, and the signal recognized by the Bluetooth device 7 to the second reed switch 5000 is 1-1-0-0-1 respectively; using the principle of analog encoder, corresponding to the attached figure, Figure 2 In the state shown, the first reed switch 4000 and the second reed switch 5000 are both in the open circuit state, and the signals are 1 and 1 respectively. Figure 3 In the state shown, the first reed switch 4000 is within the magnetic field range of the magnet 2, and the second reed switch 5000 is outside the magnetic field range of the magnet 2. The first reed switch 4000 is in a short-circuit state, and the second reed switch 5000 is in an open-circuit state. The corresponding signals are 0 and 1, respectively. Figure 4 In the state shown, the first reed switch 4000 and the second reed switch 5000 are both within the magnetic field range of the magnetic steel 2, and the first reed switch 4000 and the second reed switch 5000 are both in a short circuit state, and the corresponding signals are 0 and 0 respectively. Figure 5 In the state shown, the first reed switch 4000 is outside the magnetic field range of the magnetic steel 2, and the second reed switch 5000 is within the magnetic field range of the magnetic steel 2. The first reed switch 4000 is in an open circuit state, and the second reed switch 5000 is in a short circuit state. The corresponding signals are 1 and 0, respectively. Figure 6 In the state shown, the first reed switch 4000 and the second reed switch 5000 are both outside the magnetic field range of the magnet 2, and the first reed switch 4000 and the second reed switch 5000 are both in an open circuit state, and the corresponding signals are 1 and 1, respectively. In summary, under normal conditions, when the athlete pulls the rope, the signal of the first reed switch 4000 recognized by the Bluetooth device 7 is 1-0-0-1-1, and the signal of the second reed switch 5000 is 1-1-0-0-1.

[0065] When the rotating wheel 3 rotates multiple times, the Bluetooth device 7 recognizes that the signals of the first reed switch 4000 and the second reed switch 5000 are repeated according to the rule of the first circle;

[0066] Determination of the rope sending signal:

[0067] When the athlete sends the rope, the connecting rope drives the rotating wheel 3 to rotate, and the magnet 2 on the rotating wheel 3 moves one circle driven by the rotating wheel 3. The Bluetooth device 7 recognizes that the complete signal of the first reed switch 4000 is 1-1-0-0-1 respectively, and the Bluetooth device 7 recognizes that the complete signal of the second reed switch 5000 is 1-0-0-1-1 respectively; the Bluetooth chip 8000 and the sensing chip in the Bluetooth device 7 recognize the signals of the first reed switch 4000 and the second reed switch 5000 to determine whether the user is pulling the rope or sending the rope. The signal generation principle is the same as the step of determining the rope pulling signal. Figure 6 As shown, the first reed switch 4000 and the second reed switch 5000 are both outside the radiation range of the magnetic steel 2. At this time, the first reed switch 4000 and the second reed switch 5000 are both in an open circuit state, and the signals recognized by the Bluetooth device are both 1;

[0068] When the rotating wheel 3 rotates multiple times, the Bluetooth device 7 recognizes that the signals of the first reed switch 4000 and the second reed switch 5000 are repeated according to the rule of the first circle;

[0069] Using the principle of analog encoder, the sensing chip identifies and processes different signals of the first reed switch 4000 and the second reed switch 5000 through the Bluetooth chip 8000, and can determine the rope pulling or rope sending state. Since the rotating wheel 3 rotates multiple times each time the rope is pulled or sent, the number of rotations of the rotating wheel 3 can be determined based on the number of times the signal cycle appears.

[0070] Calculation of pull times and length:

[0071] Each time the Bluetooth device 7 obtains a rope-pulling signal and a rope-feeding signal, the number of pulls is increased by one; utilizing the above-mentioned analog encoder principle, rope-pulling and rope-feeding can be accurately determined. Each rope-pulling and rope-feeding is a motion signal. Each time a motion signal is generated, the count is increased by one. Usually, rope-pulling is not counted, but rope-feeding is counted by one, thus avoiding over-counting and missed counting.

[0072] The number of repetitions of the rope-pulling signal of the first reed switch 4000 and the second reed switch 5000 obtained by pulling the Bluetooth device 7 when pulling the rope is converted into the number of rotations of the rotating wheel 3, and the total pulling length is calculated by the number of rotations*the circumference of the rotating wheel 3.

[0073] In the steps of determining the pull rope signal:

[0074] When the connecting rope returns to the shortest state, the magnet 2 stays between the first reed switch 4000 and the second reed switch 5000. When the athlete pulls the rope, the rotating wheel 3 drives the magnet 2 to move one circle from the direction away from the first reed switch 4000 to the direction close to the first reed switch 4000. The Bluetooth device 7 recognizes that the complete signal of the first reed switch 4000 is 0-1-1-1-0-0-1-1, and the Bluetooth device 7 recognizes that the complete signal of the second reed switch 5000 is 0-0-1-1-1-0-0-1; it is a special state. Figure 8 It shows the position diagram of the initial state of the magnetic steel 2 and the first reed switch 4000 and the second reed switch 5000 in this step. The first reed switch 4000 and the second reed switch 5000 are both within the magnetic field radiation range of the magnetic steel 2, the first reed switch 4000 and the second reed switch 5000 are both in a short-circuit state, and the signals recognized by the Bluetooth device are both 0;

[0075] When the rotating wheel 3 rotates multiple times, the Bluetooth device 7 recognizes that the signals of the first reed switch 4000 and the second reed switch 5000 are repeated according to the rule of the first circle;

[0076] In the steps of determining the rope sending signal:

[0077] When the connecting rope returns to the shortest state, the magnet 2 stays between the first reed switch 4000 and the second reed switch 5000. When the athlete sends the rope, the magnet 2 moves from the direction away from the second reed switch 5000 to the direction close to the second reed switch 5000. The Bluetooth device 7 recognizes that the signal of the first reed switch 4000 is 0-0-1-1-1-0-0-1, and the Bluetooth device 7 recognizes that the signal of the second reed switch 5000 is 0-1-1-1-0-0-1-1 respectively.

[0078] When the rotating wheel 3 rotates multiple times, the Bluetooth device 7 recognizes that the signals of the first reed switch 4000 and the second reed switch 5000 are repeated according to the rule of the first rotation.

[0079] In the steps of calculating the number and length of pulls:

[0080] The Bluetooth device 7 uploads the rope pulling signal and the rope sending signal to the communication device, and the communication device calculates and displays the number of pulls and the length. Each Bluetooth device 7 has a corresponding exclusive device number. When multiple counters are placed together, the communication device will automatically identify the nearest counter and display the device number, automatically search and manually click to connect, so as to connect the communication device with the Bluetooth device 7. When the communication device leaves the effective Bluetooth distance, it will automatically prompt that the connection is disconnected. After one minute of movement stopping, the Bluetooth device 7 will automatically enter the power-saving and low-power sleep mode. In the power-saving and low-power sleep mode, the APP of the communication device cannot search for the Bluetooth device 7. In the power-saving and low-power sleep mode, the Bluetooth device 7 can be awakened by a motion signal consisting of a rope pulling signal and a rope sending signal. After awakening, the Bluetooth device 7 can be searched through the mobile phone or computer APP. To be on the safe side, 2-3 motion signals can also be used to awaken.

[0081] Based on the above, since the connecting rope is wound around the rotating wheel 3, the rotating wheel 3 will rotate with the rope when it is pulled or sent during use. During the rotation of the rotating wheel 3, the relative distance between the magnetic steel 2 and the first reed switch 4000 and the second reed switch 5000 will change. The first reed switch 4000 and the second reed switch 5000 are magnetic switch elements. The switch is closed when the magnetic field approaches and is opened when the magnetic field leaves. Since the rotation directions of the rotating wheel 3 are opposite in the rope pulling and rope sending states, the magnetic field formed by the first reed switch 4000 and the second reed switch 5000 and the rotating magnetic steel 2 is provided with two magnetic switch elements, so that the signal parameters of the first reed switch 4000 and the second reed switch 5000 obtained by the Bluetooth device 7 are different when the rotating wheel 3 rotates forward and reverse, thereby judging whether the user is pulling the rope or sending the rope. Since one rope pulling and one rope sending constitute one stretching action, the Bluetooth device 7 can count and output the number of stretching times of the tensioner 1 by recording the number of rope sending or rope pulling.

[0082] The invention has a simple structure and a reasonable design, can be used for intelligent counting during zipping, does not require self-counting, is suitable for application and promotion, and the result error obtained by adopting the counting method is small.

[0083] It should be understood that the present application is not limited to the precise structures that have been described above and shown in the drawings, and that various modifications and changes may be performed without departing from the scope thereof. The scope of the present application is limited only by the appended claims.
