[Figure 5] This is a flowchart of the fourth embodiment of the current adjustment method for exercise equipment according to this application. [Figure 6] This is a flowchart of the fifth embodiment of the current adjustment method for exercise equipment according to this application. [Modes for carrying out the invention]

[0025] The realization of the objectives, functional features, and advantages of this application will be further described with reference to the drawings, along with the examples.

[0026] It should be understood that the specific examples described herein are for illustrative purposes only and are not intended to limit this application.

[0027] In today's society, the pace of life is becoming increasingly fast, and people want to efficiently balance work, life, and physical health. Therefore, using exercise equipment to quickly achieve training results has become a popular choice. As a result, the demand for exercise equipment is growing, and the need for its use is also increasing.

[0028] Common exercise equipment includes fitness bikes, elliptical trainers, and treadmills. These exercise machines generally allow users to overcome resistance during use and achieve training effects through adjustable resistance settings. For example, a fitness bike simulates the pedaling motion of a bicycle, converting the user's energy into the bike's kinetic energy. Alternatively, a fitness bike can be equipped with a generator, converting the user's energy into the generator's kinetic energy, which in turn generates electricity, simultaneously achieving training effects.

[0029] Currently, the resistance settings on such exercise equipment are generally fixed. For example, when a user inputs a desired range, the exercise equipment outputs a corresponding resistance according to that range, and the user achieves training effects by overcoming this resistance during the exercise. After the user sets the resistance through the range, the exercise equipment outputs according to the fixed resistance during use. If the user wants to change the resistance, they need to switch the range. However, during a user's exercise, the corresponding force situation actually differs at different positions, and the resistance requirements for exercise equipment, especially equipment that inputs power by rotation, such as fitness bikes, differ. Since the power input component has different force-generating points at different positions during rotation, if the exercise equipment outputs according to a fixed resistance, the user may not feel sufficiently comfortable and will not achieve excellent training effects.

[0030] Based on this, this application provides a method for adjusting the current of an exercise machine, setting a target resistance change curve of the generator according to the resistance demand of the power input component at each power input component position when the user feels comfortable and the training effect is good. In the process of the power input component rotating, the target adjustment current of the generator is calculated by the target resistance on the target resistance change curve corresponding to each power input component position, thereby correcting the generated current of the exercise machine based on the target adjustment current corresponding to each power input component position during the exercise machine's movement process, thereby dynamically adjusting the resistance of the power input component based on this target adjustment current when the user uses the exercise machine. This allows the user to feel comfortable during training and achieve a good training effect, improving the usability of the exercise machine. This embodiment offers greater flexibility compared to controlling the resistance of the power input component of the exercise machine with a fixed generated current.

[0031] As shown in Figure 1, Figure 1 is a schematic diagram of the terminal structure of the hardware execution environment according to the embodiment of this application.

[0032] The embodiment terminal of this application may be a PC, or it may be an exercise device, such as a fitness bike.

[0033] As shown in Figure 1, this terminal may include a processor 1001, for example, a CPU, a network interface 1004, a user interface 1003, a memory 1005, and a communication bus 1002. The communication bus 1002 is used to enable connection communication between these components. The user interface 1003 may include a display and a user terminal interface, and may further include standard wired and wireless interfaces. The network interface 1004 may include a standard wired interface and a wireless interface (e.g., a Wi-Fi interface). The memory 1005 may be high-speed RAM memory or a stable memory (non-volatile memory), such as magnetic disk memory. The memory 1005 may be a storage device independent of the processor 1001.

[0034] As those skilled in the art will understand, the terminal structure shown in Figure 1 does not constitute a limitation on the terminal, and may include more or fewer components than shown, or combinations of some components, or different component arrangements.

[0035] As shown in Figure 1, the memory 1005 of the computer storage medium may include a current adjustment program that adjusts the resistance of the exercise equipment, and the processor 1001 calls the current adjustment program stored in the memory 1005, and Based on the current position of the first power input component of the aforementioned moving device, the position of the second power input component to which the power input component is about to arrive is determined. Based on the target resistance change curve of the generator, the target resistance corresponding to the position of the second power input component is determined. The aforementioned exercise equipment is used to adjust the current generated by the generator based on the target adjustment current, and to determine the target adjustment current based on the target resistance.

[0036] Based on the hardware architecture of the above-mentioned terminal, the following resistance adjustment embodiments of this application are proposed.

[0037] First Example Referring to Figure 2, the first embodiment of this application provides a method for regulating the current of an exercise machine, the method comprising the following steps.

[0038] Step S110: Based on the current position of the first power input component of the exercise equipment, the position of the second power input component to which the power input component is to arrive is determined.

[0039] The exercise equipment includes a power input component and a generator, and the power input component generates electricity when it rotates. In one embodiment, the exercise equipment may be a fitness bike. The following explanation will use a fitness bike as an example.

[0040] The principle of operation for a fitness bike is that the user rotates the power input component of the fitness bike, and as the power input component rotates, the rotor of the generator rotates, the generator rotor cuts the magnetic wires, and generates an electric current, thereby converting the user's energy into electric current.

[0041] In this embodiment, when the power input component of the fitness bike rotates, the rotational position of the power input component is detected by an infrared sensor or Hall sensor. For example, each position during one rotation of the power input component is considered the power input component position. Multiple infrared sensors or Hall sensors are provided, and the power input component position is determined based on the positions of the infrared sensors or Hall sensors of the detected power input component. Alternatively, one infrared sensor or Hall sensor is provided, and the power input component position at each point in time is calculated based on the position of the infrared sensor or Hall sensor, as well as information such as the time of the detected power input component and the rotational speed of the power input component.

[0042] In this embodiment, using the constant-speed rotation of a power input component of an exercise machine as an example, one rotation of the power input component is divided into m position points, each of which is the power input component position for resistance adjustment. When the power input component rotates to this position point, the corresponding resistance adjustment is performed. In this embodiment, the control of the adjustment current at each predicted point is calculated online, so it is necessary to predict in advance the position points where the power input component rotates and to calculate the adjustment current at these position points in advance, and furthermore, to achieve timely adjustment of the resistance of the power input component at these position points.

[0043] Therefore, in this embodiment, after the infrared sensor or Hall sensor detects the current position of the first power input component, the position of the second power input component to be reached next is determined based on the position of the first power input component. For example, in the rotational direction of the power input component, the position point that is arranged after the position of the first power input component is the position of the second power input component.

[0044] Step S120: Based on the target resistance change curve of the generator, the target resistance corresponding to the position of the second power input component is determined. The aforementioned target resistance change curve is a torque change curve of a generator that provides a comfortable and effective training experience for the human body when the position of the power input component changes.

[0045] In this embodiment, different torques are set corresponding to different power input component positions, according to the user's needs for comfort and energy conversion efficiency during the process of rotating the power input component, and a target resistance change curve that changes according to the power input component position is formed. This target resistance change curve is pre-set for the exercise equipment. During the rotation of the power input component, a corresponding target resistance is set based on the specific position of the power input component, and this is converted into a corresponding adjustment current. As a result, the resistance of the power input component is dynamically adjusted during the user's exercise using the exercise equipment, allowing the user to achieve training effects comfortably and efficiently.

[0046] In other words, when the foot of the human body moves to a different position, the resistance output by the exercise equipment changes dynamically. In one embodiment, based on the rules of foot movement on the exercise equipment, when the position of the second power input component is the first position, the target resistance corresponding to the position of the second power input component is maximum. When the position of the second power input component is the second position, the target resistance corresponding to the position of the second power input component is minimum. The rotation angle between the first position and the second position is 90 degrees or 270 degrees. For example, when the power input component is stepped on from a horizontal position of 180°, this position is the first position. When the power input component rotates from 180° to 90° or 270°, this position is the second position.

[0047] In one embodiment, a target resistance change function may be set, and when the first power input position and the second power input position are input to the target resistance change function, the target adjustment current is output. In other words, the process of steps S110 and S120 may be the process of calculating the target resistance change function.

[0048] Step S130, the exercise machine determines a target adjustment current based on the target resistance in order to adjust the output current of the generator based on the target adjustment current.

[0049] The resistance of a generator is directly proportional to the generated current; the greater the resistance, the greater the generated current. In one embodiment, after determining the target resistance, the target resistance can be converted to the corresponding target adjustment current based on the conversion relationship between the target resistance and the generated current.

[0050] In one embodiment, this embodiment can be performed during the use of an exercise machine, thereby determining a target adjustment current, adjusting the generated current of the exercise machine according to the target adjustment current, and the exercise machine adjusting the resistance of the power input component based on the adjusted generated current. The specific process can be found in the fourth embodiment below.

[0051] In one embodiment, steps S110 to S130 are the process of testing the corresponding current adjustment curve based on the target resistance change curve before using the exercise equipment. Each power input component position is tested multiple times to obtain multiple sets of target adjustment currents, and the target adjustment current corresponding to each position is modified, for example, by clustering and taking a single numerical value, taking the average value, or taking the same value with the most quantity, and the current adjustment curve of the generator is formed based on each target adjustment current when the power input component rotates at least once, and the current adjustment curve is saved. This current adjustment curve is used to fine-tune the basic generating current of the generator after the exercise equipment has been used.

[0052] During the use of the exercise equipment, the preset current adjustment curve is acquired, and based on the position of the power input component, a corresponding target adjustment current is determined from this preset current adjustment curve. Based on this target adjustment current, the basic generating current of the generator is modified, and the generator is controlled according to the modified current, thereby achieving the objective of adjusting the resistance of the power input component and adjusting the resistance of the exercise equipment.

[0053] In this embodiment, the generator's target resistance change curve is set according to the resistance demand of the power input component at each power input component position when the user feels comfortable and the training effect is good. During the rotation of the power input component, the generator's target adjustment current is calculated based on the target resistance on the target resistance change curve corresponding to each power input component position, and the current generated by the exercise equipment is adjusted based on the target adjustment current corresponding to each power input component position during the exercise equipment's movement process. By dynamically adjusting the current when the user uses the exercise equipment, the objective of adjusting the resistance of the power input component is achieved. The user can feel comfortable during training and achieve a good training effect, improving the usability of the exercise equipment. This embodiment offers greater flexibility compared to controlling the resistance of the exercise equipment's power input component with a fixed generated current.

[0054] Second Example Referring to Figure 3, this application proposes another embodiment of the current adjustment method based on the first embodiment described above, in which the current adjustment method includes the following steps.

[0055] In step S210, based on the current position of the first power input component of the exercise equipment and the motion parameters, the position of the second power input component to which the power input component is to arrive at the next time is determined.

[0056] The aforementioned motion parameters include, but are not limited to, the motion speed of the power input component (e.g., the rotational speed of the power input component). The aforementioned motion parameters are obtained by calculating based on the distance between at least two power input component positions and the time interval for rotation from the first power input component position to the second power input component position.

[0057] In this embodiment, the positions of the first and second power input components differ depending on the motion speed of the power input components. For example, if the power input component position is set to be determined each time it rotates for a certain amount of time, it is necessary to adjust the resistance of the power input component at this power input component position to generate a target resistance corresponding to this power input component position. Therefore, in the process of generating the target resistance change curve, it is necessary to match the rotational speed of the power input component, thereby more accurately determining the change in target resistance at each position under different rotational speeds.

[0058] Assuming one second is one time unit, in the current rotational scenario of the moving machine, the position of the power input component is detected and determined as the first power input component position. Based on the current rotational speed of the power input component, the position of the second power input component that the power input component is about to arrive at at the next time unit is calculated, for example, m2 = m1 + (t2 - t1) * v, where m2 is the position of the second power input component, m1 is the position of the first power input component, (t2 - t1) is one time unit, and v is the rotational speed of the power input component, i.e., the motion speed.

[0059] This allows us to obtain the position of the power input component at each adjustment time as the power input component rotates, calculate the target resistance corresponding to each power input component position based on the target resistance change curve, and then convert this into a current adjustment curve.

[0060] In one embodiment, in order to determine the position of the second power input component at which the power input component is to arrive at the next time, a motion state function is generated based on the motion parameters for at least one rotation of the power input component, and the position is determined based on the current position of the first power input component of the moving device and the motion state function, thereby improving the accuracy of position determination.

[0061] In step S220, a target resistance corresponding to the position of the second power input component is determined based on the target resistance change curve of the generator.

[0062] Step S230, the exercise machine determines a target adjustment current based on the target resistance in order to adjust the output current of the generator based on the target adjustment current.

[0063] In this embodiment, steps S220 and S230 are the same as the implementation of steps S120 and S130 in the first embodiment described above, and the specific implementation process of steps S210 and S220 can be found by referring to the first embodiment described above, and will not be explained further here.

[0064] In one embodiment, this embodiment can be performed while the exercise equipment is in use, thereby determining the target adjustment current, modifying the generated current of the exercise equipment according to the target adjustment current, and the exercise equipment adjusts the resistance of the power input component based on the modified generated current.

[0065] In one embodiment, steps S210 to S230 are the process of testing the corresponding current adjustment curve based on the target resistance change curve before using the exercise equipment. Each power input component position is tested multiple times to obtain multiple sets of target adjustment currents, and the target adjustment current corresponding to each position is modified, for example, by clustering and taking a single numerical value, taking the average value, or taking the same value with the most quantity, and the current adjustment curve of the generator is formed based on each target adjustment current when the power input component rotates at least once, and the current adjustment curve is saved. This current adjustment curve is used to fine-tune the basic generating current of the generator after the exercise equipment has been used.

[0066] In this embodiment, during the use of the exercise equipment, different preset current adjustment curves can be set based on the motion parameters of the power input components, a target adjustment current can be determined based on the different preset current adjustment curves, the basic generating current of the generator can be modified based on this target adjustment current, and then the generator can be controlled according to the modified current to adjust the resistance of the power input components. This allows the exercise equipment to adapt to the different adjustment needs under different motion parameters of the user, or to improve the accuracy of exercise equipment adjustment when different users have different motion parameters and different adjustment needs.

[0067] In this embodiment, current adjustment curves corresponding to different motion parameters can be generated based on the target resistance change curve, and the motion equipment can adaptively select the current adjustment curve based on the actual motion parameters and adapt to the resistance adjustment needs of further different usage scenarios.

[0068] Third Example Please refer to Figure 4. This application proposes another embodiment of the current adjustment method based on the first and second embodiments described above, in which the current adjustment method includes the following steps: Step S310: Based on the current position of the first power input component of the exercise equipment, the position of the second power input component to which the power input component is to arrive is determined.

[0069] In this embodiment, the specific implementation of step S310 is the same as the specific implementation of step S110 in the first embodiment described above. The specific description of step S310 in this embodiment can be found by referring to step S110 in the first embodiment described above, and will not be explained further here.

[0070] In step S320, the target resistance change curve of the generator is determined based on the motion parameters of the power input component.

[0071] This embodiment differs from the second embodiment described above in that, in this embodiment, different target resistance change curves are set depending on the motion parameters. For example, since the speed of the power input component may differ and the demand for comfort resistance of the foot may differ, for different motion parameters, the target resistance change curves that the human body finds comfortable at different power input component positions are tested and stored in memory. In the process of generating a preset adjustment current curve, the motion parameters of the power input component (such as the rotational speed of the power input component) are matched to determine a target resistance change curve that fits these motion parameters, and a corresponding preset adjustment current curve is generated based on this target resistance change curve.

[0072] Step S330: Based on the target resistance change curve, a target resistance corresponding to the position of the second power input component is determined.

[0073] Step S340, the exercise equipment determines a target adjustment current based on the target resistance in order to adjust the output current of the generator based on the target adjustment current.

[0074] In this embodiment, the specific implementation of steps S330 and S340 is the same as the specific implementation of steps S120 and S130 in the first embodiment described above, and the specific process of steps S330 and S340 can be described by referring to the first embodiment described above, and will not be explained further here.

[0075] In one embodiment, this embodiment can be performed during the use of an exercise machine, thereby determining a target adjustment current, adjusting the generated current of the exercise machine according to the target adjustment current, and the exercise machine adjusting the resistance of the power input component based on the adjusted generated current.

[0076] In one embodiment, steps S310 to S340 are the process of testing the corresponding current adjustment curve based on the target resistance change curve before using the exercise equipment. Each power input component position is tested multiple times to obtain multiple sets of target adjustment currents, and the target adjustment current corresponding to each position is modified, for example, by clustering and taking a single numerical value, taking the average value, or taking the same value with the most quantity, and the current adjustment curve of the generator is formed based on each target adjustment current when the power input component rotates at least once, and the current adjustment curve is saved. This current adjustment curve is used to fine-tune the basic generating current of the generator after the exercise equipment has been used.

[0077] In this embodiment, during the use of the exercise equipment, the equipment obtains a preset current adjustment curve based on the motion parameters of the power input component, which are determined based on these motion parameters, and then determines a target adjustment current based on this preset current adjustment curve. After correcting the basic generation current of the generator based on this target adjustment current, the generator is controlled according to the corrected current, and the resistance of the power input component is adjusted. As a result, the determined preset current adjustment curve better satisfies the resistance adjustment demand corresponding to these motion parameters, improving the adaptability of the exercise equipment.

[0078] In this embodiment, different target resistance change curves are set based on the motion parameters, generating different current adjustment curves. The exercise equipment can then adaptively select the current adjustment curve based on the actual motion parameters and adapt to the resistance adjustment needs in different usage scenarios.

[0079] Fourth Embodiment Please refer to Figure 5. This embodiment is based on all the embodiments described above, and further includes the following steps after the step of determining the target adjustment current based on the target resistance.

[0080] In step S140, after the first time interval, the target adjustment current is output, and the power generation current of the exercise equipment is adjusted based on the target adjustment current.

[0081] The first time interval may be a set time interval; for example, if the generated current is adjusted once every second, the target adjustment current will be output after 1 second.

[0082] Alternatively, the first time interval is the time length over which the power input component moves from the first power input component position to the second power input component position. The first power input component position and the second power input component position are two adjacent set positions when the power input component completes one revolution. In embodiments where the component rotates at a constant speed, the first time interval is fixed. However, in actual use, the rotation of the power input component is variable speed, so the first time interval between the first power input component position and the second power input component position changes at different positions or periods. In one embodiment, the first time interval over which the power input component moves from the first power input component position to the second power input component position is determined based on the motion parameters of the power input component.

[0083] Alternatively, the first time interval may be 0, and for example, after determining the target adjustment current, the objective of adjusting the current generated by the motion machine and further changing the resistance of the power input component can be achieved directly based on the target adjustment current.

[0084] In one embodiment, the step of adjusting the power generation current of the exercise equipment based on the target adjustment current includes taking the target adjustment current, adjusting an initial current determined based on a set range to obtain a target power generation current, and adjusting the generator of the exercise equipment based on the target power generation current.

[0085] In this embodiment, the exercise equipment is provided with a range input port, and the user can input a range into the range input port as needed, and the exercise equipment acquires the range set by the user based on the range input port.

[0086] The set range is set by the user, and different set ranges correspond to different torques; that is, in different set ranges, the exercise equipment outputs different resistances. The set range represents the initial demand for resistance when the user uses the fitness bike. In one embodiment, different settings are currently mapped to different torques, different torques are mapped to different generator currents, and the initial generator current can be determined based on the set range.

[0087] In this embodiment, different resistances are set for different power input component positions according to the user's needs for comfort and energy conversion efficiency during the process of rotating the power input component. Furthermore, a corresponding target adjustment current is set based on the specific position of the power input component during the rotation process. The generated current is then adjusted based on the initial current, thereby adjusting the resistance of the power input component. This allows the user to comfortably and efficiently achieve training effects while using the exercise equipment.

[0088] To understand this, the generated current is directly proportional to the resistance of the power input component. For example, the greater the resistance of the power input component, the greater the generated current of the generator. In this embodiment, the resistance of the power input component of the exercise equipment is adjusted by adjusting the generated current of the generator. For example, the exercise equipment controls the resistance of the power input component, and when the user overcomes the resistance of the power input component, the generator is rotated, causing the generator to produce a current close to or equal to the target generated current and output to the load.

[0089] In one embodiment, the relationship between the resistance of the generator (corresponding to the resistance of the power input component) and the generated current is as follows:

[0090] y = k1x + b, y is the generator resistance, x is the generated current, b is a constant, and k1 is a coefficient.

[0091] In this embodiment, the generated current x = x1 + x2, where X1 is the initial current determined by the set range, and X2 is the target adjustment current determined by the power input component position. The target generated current is obtained by modifying the initial current based on the target adjustment current.

[0092] In one embodiment, the method for adjusting the resistance of the power input component of the exercise equipment based on the target generated current includes, but is not limited to, the following two:

[0093] (i) Based on the target generated current, the magnetic flux of the generator is controlled and the resistance of the power input component of the motion equipment is adjusted, and the generator is an excitation motor.

[0094] In this embodiment, the generator of the motion machine is an excitation motor, and the excitation motor changes the generated current by changing the magnetic flux, and further changes the resistance of the resistor that drives the excitation motor, such as the resistance of the power input component.

[0095] In one embodiment, the target generation current is the target output current of the generator, and the target excitation current of the generator (for example, the target generation current is close to or equal to the target excitation current) is determined based on the target generation current, and the magnetic flux of the generator can be controlled based on the target excitation current of the generator.

[0096] (ii) Based on the target generation current, the load current of the generator is adjusted and the resistance of the power input component of the motion equipment is adjusted, and the generator is a permanent magnet motor.

[0097] In this embodiment, the generator of the exercise equipment is a permanent magnet motor, and the permanent magnet motor's generated current is changed by changing the load power or load current connected to the motor, and further the resistance of the resistor driving the permanent magnet motor, such as the resistance of the power input component, is also changed.

[0098] In one embodiment, the target generation current is the generator's target output current, and based on the target generation current, the load current corresponding to the load of the generator is determined, for example, by making the load current close to or equal to the target generation current, or by making the difference between the load current and the target generation current smaller than a preset value, and the generator is controlled to generate power according to the load current. That is, the generator controls the rotation of its rotor, changes the rotation information of the rotor, and further adjusts the resistance of the power input component based on the load current required for the connected load.

[0099] In this embodiment, by pre-calculating the target adjustment current at the position the power input component is about to reach, resistance adjustment can be performed directly when the power input component arrives at this position. For example, in an implementation where a generator is gradually adjusted, when the power input component rotates to the second power input component position, the generator can adjust its generated current to the target generated current. At this time, the resistance of the power input component perfectly meets the user's needs, thereby enabling real-time and online calculation of the adjustment current. Furthermore, adjusting the resistance of the power input component at each power input component position improves the effectiveness of the exercise equipment.

[0100] Fifth Example Please refer to Figure 6. This embodiment is based on the fourth embodiment described above, and in this embodiment, in order for the exercise machine to adjust the output current of the generator based on the target adjustment current, the following steps are further included after the steps of determining the target adjustment current based on the target resistance and further adjusting the resistance of the power input component of the exercise machine.

[0101] Step S150: The user obtains resistance adjustment information for the power input component, including the resistance adjustment value and the adjustment position of the power input component, which is input via the user port.

[0102] In this embodiment, the exercise equipment is provided with a user port, which is used to input usage information fed back from the user, such as resistance adjustment information for power input components.

[0103] During the user's use of the exercise equipment, the resistance of the equipment is automatically adjusted, which may result in some users not feeling sufficiently comfortable, or not feeling sufficiently comfortable at a certain position. In this case, the user can set the resistance adjustment information of the power input component via the user port. The exercise equipment retrieves the resistance adjustment information of the power input component entered by the user via the user port, and further adjusts the automatically formed information so that the exercise equipment approaches the user's requirements for comfort and training effectiveness.

[0104] Step S160: Determine the resistance adjustment value based on the resistance adjustment value and update the resistance corresponding to the power input component adjustment position in the target resistance change curve.

[0105] The user can input a resistance adjustment value by inputting an increase or decrease. For example, an exercise machine is provided with an increase button. When the increase button is triggered once, the resistance is increased by a preset value, and this preset value becomes the resistance adjustment value. When the increase button is triggered multiple times, the product of the number of triggers and the preset value becomes the resistance adjustment value.

[0106] If the resistance adjustment information for the power input component includes the power input component adjustment position, this resistance adjustment value is adopted to update the resistance corresponding to the power input component adjustment position in the target resistance change curve, and the updated target resistance change curve is saved.

[0107] If the resistance adjustment information for the power input component does not include the power input component adjustment position, and the user needs to adjust the resistance for the entire motion cycle, the target resistance change curve is updated directly based on this resistance adjustment value, for example, by increasing / decreasing the entire target resistance change curve by a small resistance adjustment value, and the updated target resistance curve is retained.

[0108] This allows the subsequent resistance adjustment to determine the target adjustment current based on the updated target resistance change curve, further update the resistance of the power input component, and adjust the resistance of the power input component in a timely manner according to the user's needs.

[0109] In this embodiment, the exercise equipment constantly adapts to the user's needs during use, improving the user experience.

[0110] In one embodiment, the generator circuit of the exercise equipment is provided with a current limiting element, such as a current limiting transistor. After determining a target adjustment current, the current limiting element of the exercise equipment is adjusted based on the target adjustment current to limit the current intensity, thereby achieving dynamic stabilization of the damping of the exercise equipment.

[0111] Sixth Example This embodiment is based on the fourth and fifth embodiments, and in this embodiment, the step of adjusting the resistance of the power input component of the sports equipment based on the target generated current is, The method further includes the step of detecting the generator type of the motion equipment, which includes a permanent magnet motor and an excitation motor.

[0112] The generator of the aforementioned exercise equipment may be configured as a permanent magnet motor or as an excited motor. A permanent magnet motor changes its generated current by changing the load power or load current connected to the motor, and further changes the resistance of the resistor driving the permanent magnet motor, such as the power input component. An excited motor changes its generated current by changing the magnetic flux, and further changes the resistance of the resistor driving the excited motor, such as the power input component. Because different types of generators have different methods for adjusting resistance, it is necessary to set different resistance adjustment programs or adjustment applications based on the motor type. This necessitates developing different programs for different generators installed in the exercise equipment, and during installation, different programs must be set based on the generator type, resulting in a complicated operation process and increased workload.

[0113] Based on this, in the resistance adjustment method according to this embodiment, when adjusting the resistance of the power input component of the exercise equipment, the generator type installed in the exercise equipment is determined based on the generator type signal stored in the system, and the resistance of the power input component of the exercise equipment can be adjusted by adopting a corresponding control method according to the generator type. As a result, by installing one program in all exercise equipment, it can be applied to exercise equipment with different generator types, or even after the exercise equipment changes generator types, there is no need to change the resistance adjustment program or adjustment application, simplifying the overall operation process and reducing the workload.

[0114] If the generator type is an excitation motor, the magnetic flux of the generator is controlled based on the target generation current.

[0115] In this embodiment, when the generator type is an excitation motor, the magnetic flux of the generator is controlled so that the generator outputs the target generation current. The specific implementation is the same as in the fourth embodiment described above, and you can refer to the fourth embodiment described above; no further explanation is given here.

[0116] If the generator type is a permanent magnet motor, the load current of the generator is adjusted based on the target generation current.

[0117] In this embodiment, when the generator type is a permanent magnet motor, the generator controls the connected load current so that the generator outputs the target generation current for the load. The specific implementation is the same as in the fifth embodiment described above, and the fourth embodiment can be referenced, and will not be described further here.

[0118] Seventh Example This embodiment is based on all of the above embodiments, and in this embodiment, after the step of adjusting the resistance of the power input component of the exercise equipment based on the target generated current, The steps include determining a target load based on the target generation current and connecting multiple loads to the generator, The control further includes the step of supplying power to the target load power from the generator.

[0119] In this embodiment, the exercise equipment includes multiple loads, and the power corresponding to each load is different. For example, the loads include, but are not limited to, flash lamps, sound devices, energy storage devices, and user terminal charging devices. The generator is connected to multiple different loads.

[0120] Furthermore, if the target generation current increases, it becomes necessary to transport current to the corresponding power load. Conversely, if the target generation current decreases, the connected load may experience a power shortage. Therefore, in this embodiment, in the process of adjusting the resistance of the power input components of the exercise equipment by adjusting the target generation current, the connected load is switched based on the target generation current to satisfy the current output and maintain a normal power supply to the load.

[0121] In one embodiment, the allocation ratio of each load may be determined by the target power generation current, and the allocation ratio of each load may be further adjusted. For example, the load may include an energy storage device and an energy consumption device. When the target power generation current increases, the allocation ratio of the energy storage device can be increased, and the energy consumption device can be maintained as is. Alternatively, when the target power generation current decreases, the allocation ratio of the energy storage device can be decreased, and the normal operation of the energy consumption device can be maintained.

[0122] However, in this specification, the terms “includes,” “compose,” or any other variation thereof are intended to include non-exclusive inclusions such that a process, method, article, or system containing a set of elements includes not only those elements but also other elements not expressly listed, or includes elements specific to such a process, method, article, or system. Unless otherwise specified, an element defined by the phrase “one…includes” does not preclude the existence of another identical element in a process, method, article, or system containing that element.
