BACKGROUND

With the rapid development of society, people often use exercise equipment to quickly achieve the effect of exercise in their busy work life. Therefore, the demand for exercise equipment is increasing and the requirements for its use are also getting higher.

Common exercise equipment includes spinning bikes, elliptical trainers, and rowing machines. These exercise equipment typically use resistance settings to help users overcome obstacles and achieve a workout. For example, a stationary bike simulates the pedaling motion of a bicycle, converting the user's energy into the bike's kinetic energy. Alternatively, an electric bicycle may have a generator that converts the user's energy into the generator's kinetic energy, which in turn generates electricity, thus providing the exercise effect.

Currently, the resistance settings of such exercise equipment are generally fixed. This means that after the user sets the resistance level, the equipment outputs a fixed resistance during use. However, when the equipment outputs a fixed resistance, the user's exercise is not comfortable enough, and the desired training effect is not achieved.

The above content is only used to help understand the technical solution of the present application and does not represent an admission that the above content is related art.

DETAILED DESCRIPTION OF THE EMBODIMENTS

It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

In today's fast-paced society, people increasingly desire to efficiently balance work, life, and health. Therefore, using exercise equipment to quickly achieve the desired workout results has become a popular choice. Consequently, the demand for exercise equipment is growing, and the requirements for its use are also becoming more stringent.

Common exercise equipment includes spinning bikes, elliptical trainers, and rowing machines. These exercise equipment typically use resistance settings to help users overcome obstacles and achieve a workout. For example, a stationary bike simulates the pedaling motion of a bicycle, converting the user's energy into the bike's kinetic energy. Alternatively, an electric bicycle may have a generator that converts the user's energy into the generator's kinetic energy, which in turn generates electricity, thus providing the exercise effect.

Currently, the resistance settings of such exercise equipment are generally fixed. For example, the user inputs the desired resistance level, and the equipment outputs the corresponding resistance. The user then overcomes this resistance to achieve the desired workout effect. After setting the resistance level, the equipment outputs a fixed resistance during use. If the user wants to change the resistance, they need to switch levels. However, during exercise, the user's actual exertion varies at different points, resulting in different resistance requirements from the equipment. This is especially true for equipment that uses rotation to input power, such as spinning bikes. The force points of the power input components differ at different positions during rotation. If the equipment outputs a fixed resistance, it will lead to discomfort for the user and will not achieve the best training effect.

Based on this, the present application discloses a resistance adjustment method and an apparatus for exercise equipment, and a non-transitory computer-readable storage medium. By obtaining a set gear level and a position of the power input component of the exercise equipment, a target generation current of the generator of the exercise equipment is determined. This target generation current controls the generator's output, thereby adjusting the resistance of the power input component. Different positions of the power input component correspond to different current adjustment values, allowing for real-time dynamic adjustment of the resistance based on the position of the power input component. The current adjustment value for each position of the power input component is configured according to comfort and optimal training effect. The exercise equipment dynamically adjusts the resistance of the power input component based on this current adjustment value, enabling users to experience both comfort and optimal training results during exercise, thus improving the user experience of the exercise equipment.

As shown in FIG. 1, FIG. 1 is a terminal structure schematic diagram of a hardware operating environment according to an embodiment of the present application.

The terminal in an embodiment of the present application can be a personal computer (PC) or an exercise equipment, such as a stationary bike.

As shown in FIG. 1, the terminal may include: a processor 1001, such as a central processing unit (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 communication between these components. The user interface 1003 may include a display screen and a user terminal interface. The user interface 1003 may also include standard wired and wireless interfaces. The network interface 1004 may include standard wired and wireless interfaces (such as a Wi-Fi interface). The memory 1005 may be high-speed random access memory (RAM) or non-volatile memory, such as disk storage. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

Those skilled in the art will understand that the terminal structure shown in FIG. 1 does not constitute a limitation on the terminal, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

As shown in FIG. 1, the memory 1005, which serves as a computer storage medium, may include a resistance adjustment program for implementing resistance adjustment of the exercise equipment. The processor 1001 may be used to call the resistance adjustment program stored in the memory 1005 and perform the following operations:

The set gear level and the position of the power input component of the exercise equipment are obtained.

The target generation current of the generator is determined based on the set gear level and the position of the power input component.

The resistance of the power input component of the exercise equipment is adjusted based on the target generation current.

Based on the hardware architecture of the aforementioned terminal, the following embodiments for adjusting resistance are proposed in the present application.

As shown in FIG. 2, an embodiment of the present application provides a resistance adjustment method for exercise equipment, including:

Step S110: obtaining a set gear level and a position of the power input component of the exercise equipment.

The exercise equipment includes a power input component and a generator. The power input component drives the generator to generate electricity when it rotates. In an embodiment, the exercise equipment can be a spinning bike. The following description uses a spinning bike as an example.

The exercise equipment is equipped with a gear level input port, where users can input a gear level according to their needs. The exercise equipment then obtains the user's set gear level based on the gear level input port.

The working principle of a stationary bike is that the user rotates the power input component of the bike, which drives the rotor of the generator to rotate. The rotor of the generator cuts magnetic field lines, thereby generation current and converting the user's energy into electrical energy.

During the use of the spinning bike provided in this embodiment, the rotational position of the power input component is detected by infrared sensors or Hall sensors. For example, the positions corresponding to one full rotation of the power input component are all considered the position of the power input component. Multiple infrared sensors or Hall sensors are set up, and the position of the power input component is determined based on the location of the infrared sensor or Hall sensor that detects the power input component. In an embodiment, a single infrared sensor or Hall sensor is set up, and the position of the power input component at various time points is calculated based on its location, the operating time of the detected power input component, the rotational speed of the power input component, and other information.

Step S120: determining a target generation current of the generator according to the set gear level and the position of the power input component.

The set gear level is configured by the user. Different set gear levels correspond to different generator torques, meaning that different set gear levels result in different resistance outputs from the exercise equipment to the power input component. The power input component also achieves the purpose of power input by overcoming resistance. The set gear level represents the user's initial resistance requirement when using the spinning bike. In an embodiment, different set gear levels correspond to different torques, and different torques correspond to different generation currents. Based on the set gear level, the first current of the generator can be determined. In an embodiment, the first current determined based on the gear level is the base current of the exercise equipment, and the resistance adjustment of the exercise equipment is a fine-tuning based on this base current.

This embodiment configures different resistances corresponding to different positions of the power input component based on the user's needs for comfort and energy conversion efficiency during the rotation of the power input component. Then, during the rotation of the power input component, the corresponding generation current is configured based on the specific position of the power input component, thereby adjusting the resistance of the power input component. This allows the user to achieve the exercise effect comfortably and efficiently while using the exercise equipment.

Therefore, in this embodiment, while determining the first current based on the set gear level, a second current is also determined based on the position of the power input component. Then, a target generation current for the generator is determined based on the first current and the second current. The generator is controlled based on this target generation current, thereby adjusting the resistance of the power input component driving the generator. For example, the sum of the first current and the second current can be determined as the target generation current. In an embodiment, the first current can be corrected based on the second current, and the corrected first current becomes the target generation current. The second current can be a correction coefficient, such as a multiple of the first current or a proportional coefficient of the first current.

In an embodiment, the second current is a correction current, which is a current that corrects the base current and is obtained through a preset current adjustment curve. That is, by testing in advance, the required resistance corresponding to each position of the power input component is determined during a full rotation of the power input component, assuming the user experiences comfortable exercise and optimal training results. Then, based on the difference between the required resistance and the initial resistance (the resistance corresponding to the base current), the resistance adjustment requirement corresponding to each position of the power input component is determined, and then the resistance adjustment requirement is converted into the correction current of the generator (that is, the second current), forming a preset current adjustment curve, which is stored in the memory.

During the movement of the exercise equipment, the preset current adjustment curve is obtained, and then the corresponding target adjustment current is determined in the preset current adjustment curve according to the position of the power input component. The target adjustment current is used as the second current to correct the first current, so that the corrected target generation current can be obtained. When the generator generates electricity based on the target generation current, the power input component has the corrected resistance, thereby achieving the purpose of adjusting the resistance of the exercise equipment.

In an embodiment, to improve the accuracy of current adjustment, a preset current adjustment curve adapted to the exercise equipment can be generated before use by the following method. For example, during the use of the exercise equipment, the power input component rotates, and the first position of the power input component at a first moment is recorded. Then, based on the first position of the power input component at the first moment, the second position of the power input component at a second moment is determined, where the second moment is the next moment after the first moment. The target resistance corresponding to the second position of the power input component is determined based on the target resistance variation curve of the generator. The second current is determined based on the target resistance, and the preset current adjustment curve is generated based on each of the second currents corresponding to the rotation of the power input component.

In an embodiment, the exercise equipment can generate the preset current adjustment curve in real time during use. For example, during the use of the exercise equipment, a first current is determined based on a set gear level, and based on the current position of the power input component (the first position of the power input component at the first moment), the position of the power input component at the next moment (the second position of the power input component at the second moment) is determined. Then, the target resistance corresponding to the position of the power input component at the next moment is determined based on the target resistance variation curve of the generator. The second current at the next moment is then calculated based on the target resistance. Furthermore, the target generation current corresponding to the position of the power input component at the next moment is determined based on the first current and the second current. Finally, the generator of the exercise equipment is controlled to generate electricity according to the target generation current, thereby adjusting the resistance of the power input component accordingly. In other words, the current adjustment value is calculated in real time by predicting the current adjustment value at the future power input component position, thus dynamically adjusting the current in real time. In this embodiment, the position of the power input component mentioned in step S110 is the position of the power input component at the next moment.

The target resistance variation curve is the generator resistance change curve that corresponds to the human body's comfort and optimal training effect when the position of the power input component changes (the generator resistance acts in the opposite direction on the power input component). This embodiment presets the target resistance variation curve, and adjusts the generation current based on the target resistance variation curve, thereby improving the accuracy of the resistance adjustment of the power input component (the resistance of the power input component is proportional to the torque of the generator).

In an embodiment, to adapt to the actual user comfort and make the current adjustment value more suitable for each user, a preset current adjustment curve adapted to the user can be generated during the use of the exercise equipment in the following way. For example, within the first 10 minutes of a user's use of the exercise equipment, based on the first position of the power input component at a first moment, the second position of the power input component at a second moment is determined (different movement speeds correspond to different second positions of the power input component, resulting in different current adjustment values). The target resistance corresponding to the second position of the power input component is determined based on the preset target resistance variation curve of the exercise equipment. The second current is determined based on the target resistance, and based on the various second currents corresponding to the rotation of the power input component, a preset current adjustment curve corresponding to the user is generated. Since the speed of the power input component varies for different users, generating a current adjustment curve adapted to the user during actual use can improve the accuracy of current adjustment. In this embodiment, the first and second moments can be pre-set, such as one moment every second. In an embodiment, the rotation of the power input component can be divided into m position points, each position point being the position of the power input component with dynamically adjusted current. The first moment is the moment when the power input component is at its current position, and the second moment is the moment when the power input component rotates to the next position.

In an embodiment, if the first moment and the second moment are predetermined time points, such as one moment every second, then the rotation speed of the power input component will differ when different users use the exercise equipment, or the same user will rotate the power input component at different speeds within different time periods. Therefore, when the speeds are different, the position reached by the power input component will be different at each moment, and the target resistance requirement will be different depending on the position of the power input component. To improve the accuracy of resistance adjustment and the adaptability of the exercise equipment in different usage scenarios, this embodiment determines the position of the power input component in the following way, thereby obtaining the target resistance at that position. For example, based on the motion parameters of the exercise equipment, including the motion speed of the power input component (such as the rotational speed of the power input component), a motion state function is generated during the rotation of the power input component. Based on the first position of the power input component at the first moment and the motion state function, the second position of the power input component at the next moment is determined. In an embodiment, the motion parameters can be calculated based on the distance between at least two positions of the power input component and the time interval from the first position of the power input component to the second position of the power input component.

In an embodiment, the exercise equipment continuously and repeatedly executes the various steps of this embodiment during use to dynamically adjust the resistance of the power input component. However, in actual use, due to external factors or factors inherent to the exercise equipment itself, the actual resistance generated may deviate from the calculated target resistance. In particular, the target resistance (torque corresponding to the first current) determined based on the set gear level may deviate. If the base torque deviates, the torque after fine-tuning based on the position of the power input component will also deviate, affecting the user experience. Therefore, to further improve the accuracy of resistance adjustment and thus enhance exercise comfort, in the resistance adjustment process of this embodiment, after determining the first current based on the set gear level, the first current is also corrected. The correction methods include, but are not limited to, the following methods.

The current generation information of the generator is acquired, the current resistance of the exercise equipment is determined based on the current generation information, that is, the actual generation information of the generator is acquired, and the actual torque of the exercise equipment or the actual resistance of the power input component is inferred through the actual generation information. The first target resistance of the exercise equipment is determined according to the set gear level, the current resistance is compared with the first target resistance, and the first current is adjusted based on the first target resistance and the current resistance. For example, if the deviation between the first target resistance and the current resistance is too large, the first current is adjusted accordingly to make the current resistance and the first target resistance close to or equal. In this way, the resistance is dynamically fine-tuned while ensuring the base resistance, avoiding excessive deviation of the actual resistance.

In an embodiment, when the current resistance is less than the first target resistance, the first current is increased; when the current resistance is greater than the first target resistance, the first current is decreased. This ensures that the difference between the current resistance and the first target resistance is less than a preset difference.

Step S130: adjusting a resistance of the power input component of the exercise equipment based on the target generation current.

The target generation current is the generator's output current, which is directly proportional to the resistance of the power input component. The greater the resistance of the power input component, the greater the generator's generation current. This embodiment adjusts the generator's generation current to adjust the resistance of the power input component of the exercise equipment. By controlling the resistance of the power input component, the user can overcome this resistance, causing the generator to rotate and produce a current close to or the same as the target generation current, which is then output to the load.

In an embodiment, the relationship between the generator feedback resistance (equivalent to the resistance of the power input component) and the generation current is as follows:

y = k ⁢ 1 ⁢ x + b

Where y is the generator resistance, x is the generation current, b is a constant, and k1 is a coefficient.

In this embodiment, the generation current x=x1+x2, where x1 is the first current determined by the set gear level and x2 is the second current determined by the position of the power input component.

In this embodiment, the target generation current of the generator of the exercise equipment is determined by acquiring the set gear level and the position of the power input component. The generator is controlled to generate electricity based on the target generation current, thereby adjusting the resistance of the power input component. Different positions of the power input component correspond to different current adjustment values, allowing for real-time dynamic adjustment of the resistance based on the position of the power input component. The current adjustment value for each position of the power input component is configured according to comfort and optimal training effect. The exercise equipment dynamically adjusts the resistance of the power input component based on this current adjustment value, ensuring both comfort and optimal training effect for the user, thus improving the overall user experience of the exercise equipment.

As shown in FIG. 3, in an embodiment, the resistance adjustment method includes the following steps.

Step S210: obtaining the set gear level and the position of the power input component of the exercise equipment.

Step S220: determining the first current based on the set gear level.

In this embodiment, steps S210 and S220 determine the first current in the same way as steps S110 and S120 in the above embodiments. The specific process of steps S210 and S220 can be referred to the above embodiments and will not be repeated here.

Step S230: determining the second target resistance corresponding to the position of the power input component according to the preset target resistance variation curve of the generator.

The difference between this embodiment and the above embodiments is that the exercise equipment in this embodiment stores the target resistance variation curve of the generator instead of the preset current adjustment curve.

In this embodiment, based on human comfort and exercise effect, a resistance change curve of the power input component during rotation is configured to obtain a target resistance variation curve, which is then stored in memory. When the exercise equipment is working, the target resistance variation curve is retrieved to obtain a second target resistance corresponding to the position of the power input component. When this second target resistance is output at the position of the power input component, it can provide the user with a better exercise effect and make the user feel comfortable. The target resistance variation curve is a torque curve that changes based on the position of the power input component.

Step S240: calculating the second current according to the second target resistance.

Step S250: determining the target generation current according to the first current and the second current.

Based on the direct proportionality between torque and generation current, the torque is converted into generation current, which is the second current corresponding to the position of the power input component. Then, based on the first current determined by the set gear level and the second current, the target generation current is calculated. The calculation method for the target generation current is the same as in the embodiments described above, and can be referred to the above embodiments.

In an embodiment, to further improve the accuracy of the adjustment and make the adjusted resistance of the power input component more suitable for the user's exercise needs, this embodiment configures a target resistance variation curve based on the motion parameters of the power input component. For example, different motion parameters correspond to different target resistance variation curves. In an embodiment, the motion parameters include, but are not limited to, motion speed. A faster motion speed indicates that the current resistance of the power input component is relatively low for the user, and in this case, the resistance of the power input component may not meet the user's needs. A slower motion speed indicates that the current resistance of the power input component is relatively high for the user, and in this case, the resistance of the power input component may be too high. Therefore, different target resistance variation curves are configured according to different motion speeds. After detecting the current motion parameters of the exercise equipment, the target resistance variation curve is determined based on the motion parameters. Then, a second target resistance corresponding to the position of the power input component is determined based on the target resistance variation curve.

Step S260: adjusting the resistance of the power input component of the exercise equipment based on the target generation current.

The target generation current is the generator's output current, which is directly proportional to the resistance of the power input component. The greater the resistance of the power input component, the greater the generator's generation current. This embodiment adjusts the generator's generation current to adjust the resistance of the power input component of the exercise equipment. By controlling the resistance of the power input component, the user can overcome this resistance, causing the generator to rotate and produce a current close to or the same as the target generation current, which is then output to the load.

In an embodiment, the relationship between the generator's resistance (equivalent to the resistance of the power input component) and the generation current is as follows:

y = k ⁢ 1 ⁢ x + b ;

Where y is the generator resistance, x is the generation current, b is a constant, and k1 is a coefficient.

In this embodiment, the generation current x=x1+x2, where x1 is the first current determined by the set gear level and x2 is the second current determined by the position of the power input component.

The exercise equipment in this embodiment allows users to experience both comfort and optimal exercise results during workouts, thus enhancing the user experience of the exercise equipment.

As shown in FIG. 4, in an embodiment, the resistance adjustment method includes the following steps.

Step S310: obtaining the set gear level and the position of the power input component of the exercise equipment.

Step S320: determining the first current based on the set gear level.

In this embodiment, steps S310 and S320 determine the first current in the same way as steps S110 and S120 in the above embodiments. The specific process of steps S310 and S320 can be referred to the above embodiments and will not be repeated here.

Step S330: obtaining the motion parameter of the power input component, and determining the second target resistance corresponding to the position of the power input component according to the preset mapping relationship between the motion parameter and torque.

This embodiment differs from the above embodiments in that, during the rotation of the power input components, the target resistance corresponding to each position of the power input component is determined based on the motion parameters of the power input components. For example, the motion parameters and the mapping relationship between the torque of the generator and the position of the power input component are pre-configured based on the test, and a mapping table or mapping data is formed and stored in the memory. When the exercise equipment is working, the second target resistance can be determined based on the motion parameters and the position of the power input component. In this embodiment, the motion parameters include, but are not limited to, the motion speed of the power input component (such as the rotational speed of the power input component). The higher the rotational speed of the power input component, the greater the second target resistance, and the lower the rotational speed of the power input components, the smaller the second target resistance.

Step S340: calculating the second current according to the second target resistance.

Step S350: determining the target generation current according to the first current and the second current.

Based on the direct proportionality between torque and generation current, the torque is converted into generation current, which is the second current corresponding to the position of the power input component. Then, based on the first current determined by the set gear level and the second current, the target generation current is calculated. The calculation method for the target generation current is the same as in the above embodiments, and can be referred to the above embodiments.

Step S360: adjusting the resistance of the power input component of the exercise equipment based on the target generation current.

The target generation current is the generator's output current, which is directly proportional to the resistance of the power input component. The greater the resistance of the power input component, the greater the generator's generation current. This embodiment adjusts the generator's generation current to adjust the resistance of the power input component of the exercise equipment. By controlling the resistance of the power input component, the user can overcome this resistance, causing the generator to rotate and produce a current close to or the same as the target generation current, which is then output to the load.

In an embodiment, the relationship between the generator's resistance (equivalent to the resistance of the power input component) and the generation current is as follows:

y = k ⁢ 1 ⁢ x + b

Where y is the generator resistance, x is the generation current, b is a constant, and k1 is a coefficient.

In this embodiment, the generation current x=x1+x2, where x1 is the first current determined by the set gear level and x2 is the second current determined by the position of the power input component.

This embodiment combines motion parameters to calculate the current adjustment value, making the calculation result closer to the current usage scenario and improving the accuracy of current regulation.

As shown in FIG. 5, this embodiment is based on all the above embodiments. In this embodiment, the step of adjusting the resistance of the power input component of the exercise equipment based on the target generation current includes:

Step S131: controlling the magnetic flux of the generator based on the target generation current to adjust the resistance of the power input component of the exercise equipment. The generator is an excitation generator.

In this embodiment, the generator of the exercise equipment is an excitation generator. The excitation generator changes the generation current by changing the magnetic flux, thereby changing the resistance driving the excitation generator, such as the resistance of the power input component.

In an embodiment, the target generation current is the target output current of the generator, and the target excitation current of the generator can be determined based on the target generation current (e.g., the target generation current is close to or equal to the target excitation current), then the magnetic flux of the generator is controlled according to the target excitation current of the generator.

The following example, with reference to FIG. 6, illustrates the resistance adjustment process during the movement of a exercise equipment using an excitation generator as its generator.

The user sets the gear level through the gear level input port, and the first current (base current or initial current) is determined based on the set gear level. An infrared sensor or Hall sensor detects the position of the power input component, and then the second current (current adjustment value) is determined based on the position of the power input component.

The data processor calculates the target generation current based on the first current and the second current. Then, it adjusts the control circuit of the excitation generator based on the target generation current, changing the magnetic flux of the excitation generator so that the output current of the excitation generator approaches or equals the target generation current. The control chip then allocates power according to the target generation current to facilitate the output of the generation current.

In this embodiment, the method for determining the first current and the second current is the same as that in any of the embodiments described above. Please refer to the above embodiments for details, which will not be repeated here.

In this embodiment, the generation current is adjusted by adjusting the magnetic flux of the excitation generator, thereby achieving the effect of current adjustment with high accuracy.

As shown in FIG. 7, this embodiment is based on all the above embodiments. In this embodiment, the step of adjusting the resistance of the power input component of the exercise equipment based on the target generation current includes:

Step S132: adjusting the load current of the generator based on the target generation current to adjust the resistance of the power input component of the exercise equipment. The generator is a permanent magnet generator.

In this embodiment, the generator of the exercise equipment is a permanent magnet generator. The permanent magnet generator changes the generation current of the permanent magnet generator by changing the power or current of the load connected to the motor, thereby changing the resistance driving the permanent magnet generator, such as the resistance of the power input component.

In an embodiment, the target generation current is the target output current of the generator. Based on the target generation current, the load current corresponding to the load of the generator is determined, such as making the load current close to or equal to the target generation current, or making the difference between the load current and the target generation current less than a preset value. Then, the generator is controlled to generate electricity according to the load current. That is, the generator controls the rotor rotation based on the load current required by the connected load. The rotor rotation information changes, thereby adjusting the resistance of the power input component.

The following example, with reference to FIG. 8, illustrates the resistance adjustment process during the movement of a exercise equipment using a permanent magnet generator.

The user sets the gear level through the gear level input port, and the first current (base current or initial current) is determined based on the set gear level. An infrared sensor or Hall sensor detects the position of the power input component, and then the second current (current adjustment value) is determined based on the position of the power input component.

The data processor calculates the target generation current based on the first current and the second current. The power control chip adjusts the load current according to the target generation current, and the permanent magnet generator adjusts its generation power according to the load current, so that the generation current is close to or equal to the load current. The power control chip can change the load current by adjusting the distribution ratio of the load current.

In this embodiment, the method for determining the first current and the second current is the same as that in any of the embodiments described above. Please refer to the above embodiments for details, which will not be repeated here.

In this embodiment, the generation current is adjusted by adjusting the current of the load connected to the permanent magnet generator, thereby achieving the effect of current adjustment and making the system highly stable.

As shown in FIG. 9. This embodiment is based on all the above embodiments. In this embodiment, the step of adjusting the resistance of the power input component of the exercise equipment based on the target generation current further includes:

Step S133: detecting the generator type of the exercise equipment. The generator type includes permanent magnet generator and excitation generator.

The generator in the exercise equipment can be configured as a permanent magnet generator or an excitation generator. A permanent magnet generator changes its generation current by changing the power or current of the load connected to the motor, thereby changing the resistance driving the excitation generator, such as the resistance of the power input component. An excitation generator changes its generation current by changing the magnetic flux, thus changing the resistance driving the excitation generator, such as the resistance of the power input component. Since different types of generators require different methods of resistance adjustment, different resistance adjustment programs or applications need to be configured according to the motor type. Different programs need to be developed based on the different generators configured for sports equipment. During installation, different programs also need to be configured according to the type of generator. The operation process is cumbersome and increases the workload.

Based on this, the resistance adjustment method proposed in this embodiment can determine the generator type of the exercise equipment based on the generator type signal stored in the system when adjusting the resistance of the power input component of the exercise equipment. Then, the corresponding control method is used to adjust the resistance of the power input component of the exercise equipment according to the generator type. In this way, only one program needs to be installed in all exercise equipment to realize the application of exercise equipment with different generator types. If the generator type of the exercise equipment is changed, there is no need to change the resistance adjustment program or the application, simplifying the entire operation process and reducing the workload.

Step S134: when the generator type is an excitation generator, controlling the magnetic flux of the generator based on the target generation current.

In this embodiment, if the generator type is an excitation generator, the magnetic flux of the generator is controlled so that the generator outputs the target generation current. The specific implementation method is the same as that in the embodiment described above, and can be referred to the embodiment described above, and will not be repeated here.

Step S135: when the generator type is a permanent magnet generator, adjusting the load current of the generator based on the target generation current.

In this embodiment, if the generator type is a permanent magnet generator, the load current connected to the generator is controlled so that the generator outputs the target generation current for the load. The specific implementation method is the same as in the embodiment described above, and can be referred to in the embodiment described above, which will not be repeated here.

As shown in FIG. 10, this embodiment is based on all the above embodiments. In this embodiment, after the step of adjusting the resistance of the power input component of the exercise equipment based on the target generation current, the resistance adjustment method further includes:

Step S140: determining the target load based on the target generation current. The generator is connected to a plurality of loads.

Step S150: controlling the generator to supply power to the target load.

In this embodiment, the exercise equipment includes a plurality of loads, each with a different power output. These loads may include, but are not limited to, flashlights, speakers, energy storage devices, user terminal charging devices, etc. The generator is connected to these multiple different loads.

It should be noted that when the target generation current increases, the current needs to be transmitted to the load with the corresponding power. When the target generation current decreases, the connected load may lack sufficient power. Therefore, in this embodiment, during the process of adjusting the resistance of the power input component of the exercise equipment by adjusting the target generation current, the connected load is switched according to the target generation current to meet the current output requirements and maintain normal power supply to the load.

In an embodiment, the allocation ratio of each load can be determined by the target generation current, and then the allocation ratio of each load can be adjusted. For example, if the load includes energy storage devices and energy consumption devices, when the target generation current increases, the allocation ratio of the energy storage devices can be increased while keeping the energy consumption devices unchanged. Alternatively, when the target generation current decreases, the allocation ratio of the energy storage devices can be decreased to maintain the normal operation of the energy consumption devices, etc.

It should be noted that, the terms “comprise”, “include” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or system that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or system.
