Description

Technical Field

[0001] The invention relates to the technical field of resistance regulation, and in particular to a dynamic power regulation system based on a resistance component. Background Art

[0002] The exercise bike, also known as the power bike, is a common traditional fitness program. Due to its high efficiency in weight loss, it is highly praised by many people who want to lose weight.

[0003] In fitness bikes, the resistance provided by resistance components is generally used to achieve the power fitness requirement. A common fitness bike in gyms now is a constant resistance fitness bike. The resistance is the resistance during riding. The faster the riding speed, the greater the power. The faster the riding speed, the greater the power consumption, and the slower the riding speed, the lower the power. In this process, the exercise effect of the human body is not ideal.

[0004] When people use this type of fitness bike to exercise, they cannot maintain a constant training power when pedaling at different speeds. Constant resistance fitness bikes cannot accurately control the resistance, and it is difficult to ensure the dynamic balance between the externally applied power and the output power of the set resistance component, which will lead to instability in the output of the equipment, and then cause the resistance and load felt by the human body during exercise to fluctuate. This fluctuation may interfere with the human body's exercise rhythm and the normal operation of the cardiopulmonary system, thereby affecting the performance of cardiopulmonary power and the effect of exercise. Summary of the invention

[0007] The resistance adjustment module is connected to the control module and is used to adjust the resistance according to the value given by the control module.

[0008] In a preferred embodiment, the setting module includes: A collection unit, used to determine a set power value; The determination unit is used to transmit the set power value to the controller for storage.

[0009] In a preferred embodiment, the detection module includes: A setting unit, used for determining the driving end to which the pressure is applied, and setting a corresponding torque sensor and a rotation speed sensor based on the driving end; The collecting and calculating unit is used to collect the torque value of the driving end to which pressure is applied through the torque sensor, collect the rotation speed of the driving end through the rotation speed sensor, transmit the torque value and rotation speed of the driving end to the controller and calculate the output power value of the driving end.

[0010] In a preferred embodiment, the data acquisition building block includes: A data acquisition unit is used to collect the output voltage of the generator and the current in the generator during the rotation of the drive end in the power car; The data calculation unit is used to perform power calculation according to the output voltage of the generator and the current in the generator to obtain the output power value.

[0011] In a preferred embodiment, the data comparison module includes: A first construction unit is used to construct a time model for applying pressure to the driving end, collect the output power value of the driving end in real time, and correspond the output power value to the time model according to the collected time to obtain a power model; A second construction unit is used to construct a standard model for setting power values ​​and compare the power model with the power standard model; A first comparison unit, used to provide a shortfall power if the output power value in the power model is less than the set power value in the power standard model; A second comparison unit is used to take the output power value in the power model as the interference power if it is greater than the set power value in the power standard model; A third comparison unit is used to treat the output power value in the power model as normal power if it is equal to the set power value in the power standard model; The management unit is used to take the gap-filling power and the excess power as difference values.

[0012] In a preferred embodiment, the control module includes: A transmission unit, used for the controller to transmit the resistance adjustment value of the resistance component corresponding to the difference value to the resistance component for resistance control; A first control unit is used to control the resistance component to increase the resistance until the output power value is equal to the set power value through the controller if the difference value is the gap-making power; The second control unit is used for controlling the resistance component to reduce the resistance until the output power value is equal to the set power value through the controller if the difference value is the interference power.

[0013] In a preferred embodiment, the resistance adjustment module adjusts the resistance according to the value given by the control module in three ways, namely: The first type is that the resistance adjustment module is composed of a generator and an electronic load connected to it.

The second type is that the resistance adjustment module is composed of a flywheel and an eddy current electromagnet.

The third type is that the resistance adjustment module is composed of a flywheel and a permanent magnet with a servo mechanism.

It uses one of the three methods of the above-mentioned resistance adjustment module to control the resistance size.

[0014] In the above technical solution, the technical effects and advantages provided by the present invention are: The present invention adjusts the resistance of the resistance component through the difference between the output power value and the set power value, so that the output power value can be continuously adjusted to the same as the set power value, so as to meet the convergence of the set power value and the actual output power value, and ensure that the human body will not feel the fluctuation of the load during exercise, and thus will not affect the human body's exercise rhythm and the normal operation of the cardiopulmonary system. The constant power fitness bike has the ability to maintain constant power at different pedaling frequencies. The most striking feature of the constant power bike is that it can accurately set and maintain a fixed power output. This means that no matter how the rider's physical condition changes, the vehicle will ensure a constant output power by adjusting the resistance, thereby ensuring that each training is scientific and efficient. This "quantitative" training method can more accurately evaluate and improve a person's cardiopulmonary endurance than traditional bicycle training. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the drawings described below are only some embodiments recorded in the present invention. For ordinary technicians in this field, other drawings can also be obtained based on these drawings.

[0016] Figure 1 It is a system block diagram of the present invention. DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example 1, please refer to Figure 1 As shown, the dynamic power regulation system based on the resistance component described in this embodiment includes: The setting module is used to determine the setting power value and is connected with the data comparison module; The acquisition module includes a detection module, which is connected to the data comparison module and is used to measure the torque value of the driving end to which pressure is applied based on the torque sensor, measure the speed of the driving end with the speed sensor, and calculate the output power value of the driving end based on the torque value and speed of the driving end acquired by the controller; A data comparison module, connected to the setting module and the acquisition module, is used to compare the output power value with the set power value to obtain a difference value, wherein the difference value includes the output power value being less than the set power value and the output power value being greater than the set power value; The control module is connected to the data comparison module and is used to control the resistance component to increase resistance through the controller if the output power value is less than the set power value, and vice versa to control the resistance component to reduce resistance, so that the output power value is close to the set power value through the resistance adjustment of the resistance component.

[0019] The resistance adjustment module is connected to the control module and is used to adjust the resistance according to the value given by the control module.

[0020] The setting module includes: The acquisition registration module is used to determine the set power value; A setting module, used for transmitting the set power value to the controller for storage; It should be noted that the user information is collected, and the user information includes the user's name, age and other basic information. The user end is registered based on the user information, and the set power value is determined based on the user end. The set power value is transmitted to the controller, which can determine the power that the user needs to output.

[0021] The detection module comprises: A setting unit, used for determining the driving end to which the pressure is applied, and setting a corresponding torque sensor and a rotation speed sensor based on the driving end; A collection and calculation unit, used to collect the torque value of the driving end to which pressure is applied through a torque sensor, collect the speed of the driving end through a speed sensor, transmit the torque value and the speed of the driving end to the controller and calculate the output power value of the driving end; It should be noted that when obtaining the output power value, it is necessary to determine the object on which the output pressure acts. Here, the object is the driving end. The corresponding torque sensor and speed sensor are set on the driving end. The torque value of the driving end to which the pressure is applied is collected by the torque sensor, and the speed of the driving end is collected by the speed sensor. The torque value and speed of the driving end are transmitted to the controller and the output power value of the driving end is calculated. The calculation formula of the output power value is: V, V is the speed, is the torque value at the driving end, The output power value can be obtained by calculating the power value obtained by the current drive end torque value and the speed. The constant power fitness bike has the ability to maintain constant power at different pedaling frequencies. The most striking feature of the constant power bike is that it can accurately set and maintain a fixed power output. This means that no matter how the rider's physical state changes, the vehicle will ensure constant output power by adjusting the resistance, thereby ensuring that every training is scientific and efficient. This "quantitative" training method can more accurately evaluate and improve a person's cardiopulmonary endurance than traditional bicycle training.

[0022] The data comparison module comprises: A first construction unit is used to construct a time model for applying pressure to the driving end, collect the output power value of the driving end in real time, and correspond the output power value to the time model according to the collected time to obtain a power model; A second construction unit is used to construct a standard model for setting power values ​​and compare the power model with the power standard model; A first comparison unit, used to provide a shortfall power if the output power value in the power model is less than the set power value in the power standard model; A second comparison unit is used to take the output power value in the power model as the interference power if it is greater than the set power value in the power standard model; A third comparison unit is used to treat the output power value in the power model as normal power if it is equal to the set power value in the power standard model; A management unit, used for taking the gap-filling power and the excess power as difference values; It should be noted that a time model for applying pressure to the driving end is constructed, wherein the time model is the timeline of the driving end being subjected to pressure. During the process of applying pressure to the driving end, the output power value of the driving end needs to be collected in real time, and the output power value is mapped to the time model according to the collected time to obtain a power model. The power model here is the correspondence between the timeline and the output power value. After that, a power standard model is constructed. The power standard model is a value of set power values ​​for various time periods. For example, in a coordinate system, time is the X-axis and the set power value is the Y-axis. Then the power standard model is a straight line on the coordinate system with a constant set power value. The power model is compared with the power standard model. If the output power value in the power model is less than the set power value in the power standard model, it is used as the gap-filling power. If the output power value in the power model is greater than the set power value in the power standard model, it is used as the surplus power. If the output power value in the power model is equal to the set power value in the power standard model, it is used as the normal power. The output power value less than the set power value and the output power value greater than the set power value are used as the difference value. The output power value in the power model is equal to the set power value in the power standard model. The difference value is not used here, and it is used to adjust the output power value according to the set power value later. The control module comprises: A transmission unit, used for the controller to transmit the resistance adjustment value of the resistance component corresponding to the difference value to the resistance component for resistance control; A first control unit is used to control the resistance component to increase the resistance until the output power value is equal to the set power value through the controller if the difference value is the gap-making power; A second control unit is used for controlling the resistance component to reduce the resistance until the output power value is equal to the set power value through the controller if the difference value is an interference power; It should be noted that the controller transmits the resistance adjustment value of the resistance component corresponding to the difference value to the resistance component for resistance control, and controls the resistance component to increase or decrease resistance in the controller. If the difference value is the gap-making power, the controller controls the resistance component to increase the resistance until the output power value is equal to the set power value. If the difference value is the interference power, the controller controls the resistance component to reduce the resistance until the output power value is equal to the set power value. For example, the value of the gap-making power is k, then the increase in resistance here is reflected in the torque value T. In order to overcome the resistance of the resistance component, a greater force needs to be applied to the driving end, then the value of the torque value T of the driving end will increase until it increases to the value P of the set power value when the T value is substituted into the calculation formula of the output power value. The output power value can be adjusted in real time so that the output power value is consistent with the set power value. For example, the user must first set the power value. At present, the output power value of most bicycles on the market is difficult to adjust to the same as the set power value. The set power is different from the actual output power, and the user cannot achieve the expected training level, and thus the actual output power cannot be consistent with the set power value, which is difficult to meet the training needs.

[0023] The transmission unit comprises: A setting unit, used for setting a unit resistance adjustment value, wherein the unit resistance adjustment value includes a unit resistance increase adjustment value and a unit resistance decrease adjustment value; A construction unit is used to set an information transmission channel between the controller and the resistance component, wherein the information transmission information includes a first channel and a second channel, the first channel is information-bound with the difference value, and the second channel is information-bound with the resistance adjustment value of the resistance component corresponding to the difference value; An adjustment unit is used to process the difference value and transmit it to the resistance component through a first channel to start a unit resistance adjustment value, process the resistance adjustment value of the resistance component corresponding to the difference value and transmit it to the resistance component through a second channel, and adjust the resistance of the resistance component to the resistance adjustment value of the resistance component corresponding to the difference value based on the adjustment component; It should be noted that the purpose of setting the unit resistance adjustment value is to make the process of lowering or increasing the resistance of the resistance component smoother, and there will be no jamming during the resistance adjustment process, making the adjustment more stable. In addition, first controlling the unit resistance adjustment value of the resistance component through the first channel can make the resistance adjustment response more real-time and rapid, and can quickly control the resistance adjustment when the output power collected is inconsistent with the set power value. Since it takes a certain amount of calculation time to obtain the resistance adjustment value of the resistance component corresponding to the difference value, there will be a time delay in adjusting the resistance of the resistance component, and it is difficult to ensure the timeliness of the resistance adjustment response. After that, the time for adjusting the resistance component through the unit resistance adjustment value can not only give the calculation time of the resistance adjustment value of the resistance component corresponding to the difference value, but also avoid the jamming of the resistance adjustment, and can avoid the discomfort of applying the driving end resistance caused by the sudden decrease or increase of the resistance.

[0024] The adjustment unit comprises: A first data processing unit, configured to set a home point between the controller and a first channel, wherein the first channel includes a positive channel and a negative channel; The second data processing unit is used to identify the difference value based on the attribution point, and if the difference value is the gap-filling power, trigger the positive channel to start transmitting the trigger instruction to the resistance component; if the difference value is the surplus power, trigger the negative channel to start transmitting the trigger instruction to the resistance component; The first trigger unit starts to increase the adjustment value of the unit resistance when the resistance component receives the trigger instruction through the positive channel; and starts to decrease the adjustment value of the unit resistance when the resistance component receives the trigger instruction through the negative channel; The second trigger unit is used to set a belonging frame on the second channel, mark a parameter definition corresponding to the belonging frame, associate the belonging frame with the function of the resistance component, extract data from the resistance adjustment value of the resistance component corresponding to the difference value to obtain parameter data (the data extracted here is the valid data in the resistance adjustment value of the resistance component corresponding to the difference value. Since the resistance adjustment value of the resistance component corresponding to the difference value controls the resistance adjustment of the resistance component, and the resistance adjustment of the resistance component is achieved through the current value, the resistance adjustment value of the resistance component corresponding to the difference value here can be converted into the current value of the resistance of the corresponding resistance component for transmission), place the parameter data corresponding to the parameter definition in the belonging frame for transmission through the second channel, and the resistance component receives the belonging frame, and based on the association relationship between the belonging frame and the function of the resistance component, the parameter data is loaded on the resistance component for operation; It should be noted that the purpose of setting the attribution point on the first channel is to distinguish whether the difference value corresponds to the start-up unit resistance increase adjustment value or the unit resistance decrease adjustment value. After the resistance component receives the instruction, there is no need to judge the data, and the unit resistance increase adjustment value or the unit resistance decrease adjustment value is obtained directly according to the positive channel and the negative channel. The trigger instruction here is only used as data transmitted in the positive channel and the negative channel. It does not matter what the trigger instruction content is. The purpose is to have a small amount of data and fast transmission. When the resistance component receives the trigger instruction through the positive channel, it starts the unit resistance increase adjustment value; when the resistance component receives the trigger instruction through the negative channel, it starts the unit resistance decrease adjustment value. An attribution box is set on the second channel, and the parameter definition is marked in the corresponding attribution box. The attribution box is associated with the function of the resistance component, and the resistance adjustment value corresponding to the difference value is extracted to obtain parameter data. The parameter data corresponding to the parameter definition is placed in the attribution box. The data is transmitted through the second channel, and the resistance component receives the belonging frame. Based on the association between the belonging frame and the function of the resistance component, the parameter data is loaded on the resistance component for operation. Here, there are an infinite number of belonging frames between the second channel and the controller. The corresponding belonging frame marks the parameter definition, and the belonging frame is associated with the function of the resistance component. There are multiple frames in the belonging frame, which can be used to load different parameter data, such as voltage, current and other parameter definitions. The belonging frame is associated with the function of the resistance component. The function of the resistance component is to adjust the current on the resistance component. In this way, the parameter data can be directly loaded on the component corresponding to the resistance component. After the resistance component receives the parameter data, it does not need to process the data and is directly loaded on the component corresponding to the function of the resistance component, so that the resistance adjustment is faster, the efficiency and responsiveness of the resistance adjustment can be accelerated, and the output power adjustment can be more in line with the set power value. The resistance adjustment module includes: a generator and an electronic load.

[0025] It should be noted that by changing the electronic load connected to the generator, the current in the generator circuit can be controlled, and then the torque provided by the system can be changed, so that the system power is close to the set power. The driving wheel is the power input end, and a driving wheel pulley is also provided on the wheel shaft on one side of the driving wheel. A speed sensor is provided on one side of the driving wheel, and a pulley is provided at one end of the rotating shaft of the speed sensor. The torque sensor is located between the driving wheel and the resistance control component, and a torque sensor sprocket is provided at one end of the rotating shaft of the torque sensor, and a torque sensor pulley is provided at the other end. The torque sensor sprocket and the driving wheel are connected by a chain. The resistance control component includes a generator and an electronic load module, and a resistance component pulley is provided at one end of the rotating shaft of the generator. The resistance component pulley and the torque sensor pulley are connected by a transmission belt, and a pressure pulley is provided on one side of the transmission belt.

[0026] When this embodiment is used: the driving wheel drives the torque sensor to rotate through the chain, and the torque sensor drives the generator to rotate through the torque sensor pulley, the transmission belt and the resistance component pulley. The controller receives the torque T and the speed V detected by the torque sensor and the speed sensor, and calculates the real-time exercise power P according to the formula P=V×T and compares it with the set power value of the power car. The controller adjusts the size of the electronic load to adjust the current in the generator circuit, thereby adjusting the resistance provided by the generator. When the resistance of the generator is changed, the torque provided by the system to the outside can be controlled, so that the system power tends to the set power value, thereby maintaining the stability of the power of the power car and achieving constant power fitness.

[0027] Embodiment 2: The setting module, acquisition module, data comparison module and control module are the same as those in Embodiment 1, except that the resistance adjustment module is composed of a flywheel and an eddy current electromagnet, and the way to adjust the resistance according to the value given by the control module is replaced by: adjusting the current flowing into the eddy current electromagnet, changing the magnetic force of the eddy current electromagnet to adjust the resistance of the flywheel, so that the resistance of the flywheel changes, and the resistance provided by the system to the outside can be controlled, so that the system power tends to the set power value; It should be noted that by adjusting the current flowing into the eddy current electromagnet and changing the magnetic force of the eddy current electromagnet to adjust the resistance of the flywheel, the resistance of the flywheel changes, and then the resistance provided by the system can be controlled, so that the system power tends to the set power value. The driving wheel is the power input end, and a driving wheel pulley is also provided on the axle on one side of the driving wheel. The torque sensor is located between the driving wheel and the resistance control component. A torque sensor sprocket is provided at one end of the rotating shaft of the torque sensor, and a torque sensor pulley is provided at the other end. The torque sensor sprocket and the driving wheel are connected by a chain. At the same time, the speed sensor device is connected to the driving wheel through a transmission belt. The resistance control component includes a flywheel and an eddy current electromagnet. A resistance component pulley is provided at one end of the rotating shaft of the flywheel. The resistance component pulley and the torque sensor pulley are connected by a transmission belt, and a pressure pulley is provided on one side of the transmission belt.

[0028] When this embodiment is used: the driving wheel drives the torque sensor to rotate through the chain, and the torque sensor drives the flywheel to rotate through the torque sensor pulley, the transmission belt and the resistance component pulley. The controller receives the torque T and the speed V detected by the torque sensor and the speed sensor, and calculates the real-time exercise power P according to the formula P=V×T and compares it with the set power value of the power car. The controller adjusts the current flowing into the eddy current electromagnet, changes the magnetic force of the eddy current electromagnet, and thus adjusts the resistance of the flywheel. When the resistance of the flywheel is changed, the resistance provided by the system to the outside can be controlled, so that the system power tends to the set power value, keeps the power of the power car stable, and achieves constant power fitness.

[0029] The setting module, acquisition module, data comparison module and control module in Example 3 are the same as those in Example 1, except that the resistance adjustment module is composed of a flywheel and a permanent magnet under the control of a servo mechanism, and the way to adjust the resistance size according to the value given by the control module is replaced by: controlling the servo mechanism to adjust the distance between the permanent magnet and the flywheel to adjust the resistance output of the flywheel, so that the resistance provided by the flywheel is changed, and the resistance provided by the system to the outside can be controlled so that the system power tends to the set power value; It should be noted that the control servo mechanism adjusts the distance between the permanent magnet and the flywheel to adjust the resistance output of the flywheel so that the system power tends to the set power value. The resistance control component is a flywheel and a permanent magnet. A servo mechanism is provided on one side of the permanent magnet. The servo mechanism is installed on the base of the resistance control component. The rotating shaft of the servo mechanism is connected to the lower side of the permanent magnet. The speed measuring device is a speed sensor, which is installed behind the flywheel.

[0030] When this embodiment is used, the torque sensor measures the output torque value, and the speed measuring device is connected to the flywheel, and the speed of the flywheel is measured. The speed of the drive wheel can be obtained by converting the transmission ratio between the drive wheel and the drive wheel, and the real-time motion power is calculated according to the formula P=V×T. Because the permanent magnet can cause the flywheel to generate resistance through the eddy current effect, the servo mechanism is controlled to adjust the distance between the permanent magnet and the flywheel, thereby adjusting the resistance of the flywheel. When the resistance of the flywheel is changed, the resistance provided by the system can be controlled, so that the system power tends to the set power value, the power of the power car is kept stable, and constant power fitness is achieved.

[0031] The setting module, data comparison module, control module and resistance adjustment module in Example 4 are the same as those in Example 1, except that: The acquisition module adopts a data acquisition building module, which is used to collect the output voltage of the generator and the current in the generator to obtain the output power value of the generator. Based on the output power of the generator, the controller calculates the output power value of the drive end; It should be noted that when obtaining the output power value, it is necessary to determine the object on which the output pressure acts. Here, the object is the drive end. A corresponding data acquisition construction module is set on the drive end. Through this module, the output voltage and current of the generator driven by the drive end are collected, and the output power of the generator is calculated. The calculation formula for the output power value of the generator is: I, U is the current generator output voltage, I is the current generator output current value, To output the power value, the output power of the generator is transmitted to the controller and the output power value of the drive end is calculated, and the power value corresponding to the current drive end can be obtained. The above conclusion is under ideal conditions. In actual conditions, the generator efficiency and mechanical transmission loss will affect the power accuracy. In order to eliminate the above situation, a correction factor K can be introduced. The correction factor can eliminate the system loss and make the output power value approach the actual power value; the correction factor is a series of data obtained from empirical values ​​at different speeds and different powers.

[0032] By changing the electronic load connected to the generator, the current in the generator circuit can be controlled, and the power provided by the system can be changed, so that the system power is close to the set power. The driving wheel of the resistance control component is the power input end, and the driving wheel and the resistance control component are connected through an intermediate transmission shaft. A sprocket is provided at one end of the intermediate transmission shaft, and a pulley is provided at the other end. The sprocket and the driving wheel are connected by a chain. The resistance control component includes a generator and an electronic load module. A resistance component pulley is provided at one end of the generator shaft. The resistance component pulley and the intermediate transmission shaft pulley are connected through a transmission belt, and a pressure pulley is provided on one side of the transmission belt.

[0033] When this embodiment is used: the driving wheel drives the generator to rotate through the intermediate transmission shaft, and the data acquisition construction module collects the output voltage of the generator and the current in the generator according to the formula I, calculates the real-time exercise power P and compares it with the set power value of the power car. The controller adjusts the size of the electronic load to adjust the current in the generator circuit, thereby adjusting the output power provided by the generator. When the output power of the generator is changed, the power provided by the system can be controlled, so that the system power tends to the set power value, maintaining the stability of the power car power and achieving constant power fitness.

[0034] Example 5, please refer to Figure 1 As shown, the dynamic power regulation system based on the resistance component described in this embodiment includes: A setting module is used to determine the set power value before starting work; The acquisition module includes a data acquisition building module, which is connected to the setting module and is used to acquire the output voltage of the generator and the current in the generator to obtain the output power value, and to build an adjustment model based on the output power value. The driving end here includes driving components such as cranks, driving wheels and sprockets on the bicycle; A data comparison module, connected to the setting module and the acquisition module, is used to compare the output power value with the set power value to obtain a difference value, wherein the difference value includes the output power value being less than the set power value and the output power value being greater than the set power value; The control module is connected to the data comparison module and is used to control the resistance component to increase resistance through the controller if the output power value is less than the set power value, and vice versa to control the resistance component to reduce resistance, so that the output power value is close to the set power value through the resistance adjustment of the resistance component.

[0035] The resistance adjustment module is connected to the control module and is used to adjust the resistance according to the value given by the control module.

[0036] The setting module includes: The acquisition registration module is used to determine the set power value; A setting module, used for transmitting the set power value to the controller for storage; It should be noted that the user information is collected, and the user information includes basic information such as the user's name and age. The user end is registered based on the user information, and the set power value is determined based on the user end. The set power value is transmitted to the controller for storage, which can determine the energy that the user needs to output.

[0037] The data acquisition building block includes: Setting a storage surface, setting a grid based on the storage surface, marking a power value on the grid, obtaining a data layout, and positioning the set power value mark on the data layout; The output voltage of the generator and the current in the generator are collected to calculate the output power value; Mark the output power value on the data panel for positioning; Planning a set power value trend line on the grid, and setting the set power value trend line based on the power value on the grid; Collect output power values ​​in real time, plan output power trend lines on the grid based on the output power values, limit the output power trend lines by regions according to the grid to obtain regional output power trend lines, and set multiple regional ports on the data page, wherein the regional ports are composed of multiple sub-contact connections; Corresponding characteristics are respectively assigned to the corresponding sub-contacts; The data comparison module includes: enabling the corresponding regional port based on the regional output power trend line, and grabbing and connecting multiple sub-contacts in the regional port with the regional output power trend line and the set power value trend line through features; The output power trend line is regionally limited according to the preset power value range to obtain a regional output power trend line, and a corresponding regional port is configured for the corresponding regional output power trend line; Based on the multiple regional output power trend lines, the set power value trend line is correspondingly divided to obtain multiple regional set power value trend lines, and the regional output power trend line is bound to the corresponding regional set power value trend line to obtain the corresponding relationship between the regional port and the set power value trend line; Multiple sub-contacts respectively correspond to the regional output power trend line and the set power value trend line to capture data; Based on time, the sub-contacts of the data capture regional output power trend line and the set power value trend line are matched, and the sub-contacts are communicated and implicated in real time. The regional port activation feature is calculated based on the data on the regional output power trend line and the set power value trend line obtained by the sub-contact, wherein the regional port activation feature is the difference power value between the current regional output power trend line and the corresponding set power value trend line. If the output power corresponding to the current regional output power trend line is less than the set power value of the corresponding set power value trend line, the regional port activation feature is a negative value; if the output power corresponding to the current regional output power trend line is greater than the set power value of the corresponding set power value trend line, the regional port activation feature is a positive value, and the output power value is obtained to construct an adjustment model; It should be noted that, through the power setting and layout binding algorithm, this function is responsible for binding the power value set by the user to the specified position of the data layout, ensuring the intuitive display and subsequent application of the set power value; The function of the generator data acquisition algorithm is to collect the output voltage and current of the generator in real time. These data are the basis for calculating the output power. The core operation is to read the voltage and current values ​​of the generator through the hardware interface or sensor to ensure the accuracy and real-time nature of the data.

[0038] The function of the output power calculation algorithm is described as calculating the output power of the generator based on the collected voltage and current values; the core operation is to calculate the output power by applying the power calculation formula (such as P=UI).

[0039] The function of the output power layout marking and positioning algorithm is described as marking the calculated output power value at the specified position of the data layout and visually comparing it with the set power value; the core operation is to format the calculated output power value and render it to the corresponding area of ​​the data layout according to the layout rules.

[0040] The function of the power correspondence analysis and adjustment algorithm is described as analyzing the correspondence between the set power value and the output power, and adjusting the output power according to the analysis results to make it as close to the set power value as possible; the core operation is divided into the analysis stage: comparing the difference between the set power value and the output power to evaluate whether adjustment is needed; the adjustment stage: according to the size and direction of the difference, try to adjust the output power by controlling the working state of the generator (such as adjusting the load, optimizing the power generation efficiency, etc.); feedback loop: continuously monitor the adjusted output power until it meets the predetermined conditions with the set power value (such as within the error range); here, the data layout is set, and the set power value is marked on the data layout for positioning. The positioning is to bind the set power value to the data layout, and then collect the output voltage of the generator and the current in the generator to calculate the output power value. After obtaining the output power value, it is marked on the data layout and positioned. Then, the correspondence between the output power value and the set power value on the data layout can ensure the adjustment of the output power value through this correspondence; define the storage surface to determine a two-dimensional plane as the storage surface of the power data. This storage surface is a storage device for the plane storage layout. The storage surface is divided into multiple small grids (such as square or rectangular grids) and used to store The power value at the position is represented by a two-dimensional array or matrix to represent the grid. Each element of the array corresponds to a grid and stores the power value of the grid. Then, a series of paths are planned on the grid. In this process, the output power is collected in real time and the output power trend line is planned in real time. The power flow direction path is represented, including the set power value trend line and the output power trend line. The direct difference between the output power trend line and the set power value trend line can be obtained for subsequent adjustment of the output power trend line. The path planning algorithm in graph theory (such as Dijkstra algorithm) is used to plan the power trend line. Here, the complete output power trend line is not planned first and then the area is limited. Instead, the output power value is collected in real time and the output power trend line is planned and limited according to the area at the same time. The limitation according to the area here is according to the preset power value range; the output power value is collected in real time and the output power trend line is planned, and the output power value is obtained in real time through sensors or other devices; the output power trend line is planned: according to the power value collected in real time, the output power flow path is planned on the grid; the output power trend line is divided into regions according to the grid to obtain multiple regional output power trend lines; dynamic programming or greedy algorithm is used to adjust the output power flow path in real time.When dividing the area, the area boundary can be defined according to the coordinates of the grid or the distribution of power values, and then a corresponding relationship between the output power trend line of each area and the area port is established. When the output power flows to a certain area, the port of the area is enabled according to the corresponding relationship; a hash table or dictionary is used to store the corresponding relationship between the area and the port; when it is detected that the output power enters a certain area, the corresponding port is enabled by looking up the corresponding relationship; the area port enabling feature is set and the output power value is located, and the area port enabling feature is the difference power value between the enabled output power and the set power value; in actual use, data visualization technology (such as heat map, contour map, etc.) can be used to display the distribution of output power values ​​on the data page; the data page is updated in real time to reflect the enabling status of the area port and the change of the output power value, which can facilitate the subsequent quick adjustment of the resistance of the resistance component through the generator, and the faster response to the resistance adjustment, and the process of adjusting the resistance of the resistance component is more stable and faster. Initialize a set A containing multiple regional ports, each of which maintains a sub-contact list; traverse the sub-contacts of each regional port, and assign features to each sub-contact according to business needs. These features include the regional output power trend line corresponding to the sub-contact for identification and connection and the reference feature for the set power value trend line, which is used to adjust and verify the power value; connect to the regional output power trend line and the set power value trend line respectively; when there is data flow in the regional output power trend line, the corresponding regional port enabling logic is triggered by searching and matching feature identifiers, so that the difference data can be accurately and quickly acquired in the future. In the data layout, while acquiring the difference value, the current of the generator can be adjusted in real time through the regional port to ensure that the corresponding port can be quickly enabled to acquire the data value and transmit the acquired difference power value to the resistance component for adjusting the current of the resistance component so that the resistance component obtains the output power corresponding to the set power value under the adjustment of current and voltage, so that the subsequent generator output power value is the same as the set power value, and a continuous balance relationship between the set power value and the output power is achieved;. According to the preset power value range, the interval division algorithm (here the preset power value range is used) is used to finely divide the output power trend line of the output to generate multiple independent output power trend lines; each area is assigned a specific port, which is responsible for managing and adjusting the power range value of the output power trend line. This step ensures the accuracy and flexibility of power management; based on the obtained multiple output power trend lines, a mapping matching algorithm (such as nearest neighbor matching, linear interpolation matching, etc.) is used to regionalize the set power value trend line accordingly (the corresponding division standard here can be time, the power value is marked on the grid, and a space for the time mark is also given. The start time of the generator operation is marked on the space given the time mark. The output power value is collected in real time and marked on the data board in real time and constructed into an output power trend line. The port is pre-set on the data board. A port is enabled in the preset power value range and set on the corresponding output power trend line. After the output power trend line ends at the preset power value range, it serves as a regional output power trend line, and the corresponding regional port ends. The next regional output power trend line corresponds to another regional port. When the output power trend line is generated, the regional port will correspond. When a regional output power trend line ends, the corresponding regional port will no longer work), forming multiple set power value trend lines. Each regional output power trend line is bound to its corresponding regional set power value trend line through a binding algorithm (such as key-value pair binding, index binding, etc.), and a linear interpolation matching algorithm is used to find the corresponding point on the set power value trend line according to the boundary value of the regional output power trend line, and the corresponding regional set power value trend line is divided accordingly. Then, each regional port is bound to the corresponding regional set power value trend line through a hash table or array index, and a clear correspondence between the regional port and the set power value trend line is established; and an enable feature is set for each regional port. This feature is defined as the difference power value between the current regional output power trend line and the corresponding regional set power value trend line. This difference value is calculated and updated in real time through a difference calculation algorithm (such as direct subtraction, weighted difference calculation, etc.), so that the system can adjust or optimize the power allocation strategy accordingly, and can quickly enable the corresponding port to obtain data values ​​and transmit the obtained difference power value to the resistance component for adjusting the current of the resistance component, so that the resistance component obtains the output power of the corresponding set power value under the adjustment of current and voltage, so that the subsequent generator output power value is the same as the set power value, and a continuous balance relationship between the set power value and the output power is achieved.

[0041] The sub-contacts monitor the regional output power trend line and the set power value trend line respectively, and are used to obtain data on the regional output power trend line and the set power value trend line. When obtaining data on the regional output power trend line and the set power value trend line in real time, they follow the regional output power trend line and the set power value trend line to move according to time. The time is the starting time of the operation of the resistance component after the set power value is set. The sub-contacts on the regional output power trend line and the set power value trend line are communication-involved, and the communication-involved sub-contacts are communication-connected according to time, wherein the communication-involved sub-contacts on the regional output power trend line and the set power value trend line correspond to each other one-to-one and are communication-connected. Afterwards, the regional port activation feature is calculated by calculating the data on the regional output power trend line and the set power value trend line obtained by the sub-contacts, which can be used to collect the regional output power trend line and compare it, and obtain the control information for adjusting the generator current, so as to achieve the purpose of fast and real-time adjustment process.

[0042] The control module comprises: Establish connections between all regional ports and generators; The regional port enabling feature is transmitted to the generator through the corresponding regional port to adjust the current of the generator. If the regional port enabling feature is a negative value, the current of the generator is increased; if the regional port enabling feature is a positive value, the current of the generator is reduced until the output power value of the generator is the same as the set power value; It should be noted that all regional ports have a communication connection relationship with the generator. When the output power trend line constructed by the output power value progresses to a certain regional output power trend line, the corresponding regional port is enabled, and other regional ports are closed. The corresponding regional port is responsible for the corresponding regional output power trend line. Then, the regional port activation feature obtained through the data layout is transmitted to the generator, and the current of the generator is adjusted until the output power value of the generator is the same as the set power value. The regional port activation feature is obtained through the data collected by the sub-contact; In Embodiment 5, the resistance adjustment module adjusts the resistance according to the value given by the control module by changing the electronic load connected to the generator and controlling the current in the generator circuit so that the output power of the generator tends to the set power value; It should be noted that by changing the electronic load connected to the generator, the current in the generator circuit can be controlled so that the output power P=U×I of the generator tends to the set power value, thereby achieving constant power fitness; when the output power of the generator is the same as the set power value, the power value of the resistance component driven by the generator is also the same as the set power value.
