Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of resistance adjustment, in particular to a dynamic power adjustment system based on a resistance assembly. BACKGROUND

[0002] A fitness bike, also known as a power bike, is a common traditional fitness project. It is highly efficient for weight loss and is highly praised by many people who want to lose weight.

[0003] In a fitness bike, resistance provided by a resistance assembly is generally used to achieve the requirement of power fitness. A constant resistance type fitness bike is commonly used in gyms. The resistance is the resistance during cycling. The faster the cycling speed, the greater the power. The faster the cycling speed, the greater the power consumption. The slower the cycling speed, the smaller the power. The effect of human body movement is not ideal.

[0004] When people use such fitness bikes for exercise, they cannot maintain a constant training power when the pedaling speed is different. The constant resistance type fitness bike cannot accurately control the resistance, and it is difficult to ensure the dynamic balance between the external applied power and the output power of the set resistance assembly. This will cause instability in the output of the device, and in turn cause fluctuations in the resistance and load felt by the human body during movement. This fluctuation may interfere with the movement rhythm of the human body and the normal work of the heart and lung system, thereby affecting the performance of the heart and lung power and the exercise effect.

Obviously, the drawings described below are only some embodiments of the present application, and other drawings can also be obtained by those skilled in the art based on these drawings.

[0041] Figure 1 The system block diagram of the present application. DETAILED DESCRIPTION

[0042] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0043] Embodiment 1, please refer toFigure 1 The dynamic power adjustment system based on the resistance assembly comprises:

[0044] The setting module is configured to determine a set power value and is connected to the data comparison module.

[0045] The acquisition module comprises a detection module connected to the data comparison module, which is configured to measure the torque value of the driving end subjected to pressure based on a torque sensor, measure the rotating speed of the driving end based on a rotating speed sensor, and calculate the output power value of the driving end based on the torque value and the rotating speed of the driving end obtained by the controller.

[0046] The data comparison module is connected to the setting module and the acquisition module, and is configured to compare the output power value with the set power value to obtain a difference value, wherein the difference value comprises the output power value being less than the set power value and the output power value being greater than the set power value.

[0047] The control module is connected to the data comparison module, and is configured to control the resistance assembly to increase the resistance if the output power value is less than the set power value, and control the resistance assembly to decrease the resistance if the output power value is greater than the set power value, so that the output power value and the set power value tend to be close to each other through the resistance adjustment of the resistance assembly.

[0048] The resistance adjustment module is connected to the control module, and is configured to adjust the resistance value according to the value given by the control module.

[0049] The setting module comprises:

[0050] The acquisition registration module is configured to determine the set power value.

[0051] The setting module is configured to transmit the set power value to the controller for storage.

[0052] It should be noted that the user information is collected, and the user information includes basic information such as the name and age of the user. The user end is registered based on the user information, the set power value is determined based on the user end, the set power value is transmitted to the controller, and the power output by the user can be determined.

[0053] The detection module comprises:

[0054] The setting unit is configured to determine the driving end subjected to pressure, and set corresponding torque sensors and rotating speed sensors based on the driving end.

[0055] The acquisition calculation unit is configured to acquire the torque value of the driving end subjected to pressure through the torque sensor, acquire the rotating speed of the driving end through the rotating speed sensor, and transmit the torque value and the rotating speed of the driving end to the controller and calculate the output power value of the driving end.

[0056] It should be noted that when the output power value is obtained, the object on which the output pressure acts needs to be determined, and the object here is the driving end. A corresponding torque sensor and a rotational speed sensor are arranged 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 rotational speed of the driving end is collected by the rotational speed sensor. The torque value and the rotational 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 rotational speed, is the torque value of the driving end, is the output power value. The constant power fitness vehicle can obtain the power value calculated by the current driving end torque value and the rotational speed. The constant power fitness vehicle can maintain constant power at different pedal frequencies. The most noticeable feature of the constant power vehicle is that it can accurately set and maintain a fixed power output. This means that regardless of the physical state of the rider, the vehicle will ensure 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 the individual's cardiorespiratory endurance than traditional bicycle training.

[0057] The data comparison module comprises:

[0058] The first construction unit is configured to construct a time model of 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 collection time to obtain a power model.

[0059] The second construction unit is configured to construct a constant power value standard model, and compare the power model with the power standard model.

[0060] The first comparison unit is configured to use the output power value in the power model as a complementary power if the output power value is less than the set power value in the power standard model.

[0061] The second comparison unit is configured to use the output power value in the power model as an excess power if the output power value is greater than the set power value in the power standard model.

[0062] The third comparison unit is configured to use the output power value in the power model as a normal power if the output power value is equal to the set power value in the power standard model.

[0063] The management unit is configured to use the complementary power and the excess power as difference values.

[0064] It should be noted that the time model for applying pressure to the driving end is constructed, the time model is a time line for the driving end being applied with pressure, the output power value of the driving end needs to be collected in real time during the process of the driving end being applied with pressure, the output power value is corresponded to the time model according to the collection time to obtain a power model, the power model is a corresponding relationship between the time line and the output power value, then a power standard model is constructed, the power standard model is a value of a set power value in various time periods, for example, in a coordinate system, the time is the X axis, and the set power value is the Y axis, so the power standard model is a straight line of the set power value unchanged in the coordinate system, the power model and the power standard model are compared, if the output power value in the power model is less than the set power value in the power standard model, the output power value is regarded as a complementary power, if the output power value in the power model is greater than the set power value in the power standard model, the output power value is regarded as an excess power, if the output power value in the power model is equal to the set power value in the power standard model, the output power value is regarded as a normal power, the output power value less than the set power value and the output power value greater than the set power value are regarded as difference values, the output power value equal to the set power value in the power model does not have a difference value, which is used for subsequent adjustment of the output power value according to the set power value;

[0065] The control module comprises:

[0066] The transmission unit is configured to transmit, by the controller, the resistance adjustment value of the resistance component corresponding to the difference value to the resistance component for resistance control.

[0067] The first control unit is configured to, if the difference value is the complementary power, control the resistance component to increase the resistance by the controller until the output power value is equal to the set power value.

[0068] The second control unit is configured to, if the difference value is the excess power, control the resistance component to decrease the resistance by the controller until the output power value is equal to the set power value.

[0069] 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. In the controller, the resistance of the resistance component is increased or decreased. If the difference value is the make-up power, the resistance of the resistance component is increased by the controller until the output power value is equal to the set power value. If the difference value is the excess power, the resistance of the resistance component is decreased by the controller until the output power value is equal to the set power value. For example, the value of the make-up power is k. Here, the increase in resistance 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. Therefore, the torque value T of the driving end increases until the value of T is substituted into the calculation formula of the output power value, which is equal to the value P of the set power value. The output power value can be adjusted in real time to make the output power value consistent with the set power value. For example, the user first sets the power value. At present, the output power value of most bicycles on the market is difficult to adjust to be consistent with the set power value. The set power value is different from the actual output power value. Therefore, the user cannot achieve the desired training level, and the actual output power value cannot be consistent with the set power value, which cannot meet the training requirements.

[0070] The transmission unit comprises:

[0071] The setting unit is configured to set a unit resistance adjustment value, wherein the unit resistance adjustment value comprises a unit resistance increase adjustment value and a unit resistance decrease adjustment value.

[0072] The building unit is configured to set an information transmission channel between the controller and the resistance component, wherein the information transmission channel comprises a first channel and a second channel. The first channel is information-bound to the difference value, and the second channel is information-bound to the resistance adjustment value of the resistance component corresponding to the difference value.

[0073] The adjustment unit is configured to process the difference value and transmit it to the resistance component through the first channel to start the 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 the second channel. On the basis of the adjustment component, the resistance of the resistance component is adjusted according to the resistance adjustment value of the resistance component corresponding to the difference value.

[0074] It should be noted that the unit resistance adjustment value is set to make the process of reducing or increasing the resistance of the resistance assembly more smooth, so as to avoid the situation that the resistance is adjusted in the process of adjusting the resistance, so as to make the adjustment more stable. In addition, the unit resistance adjustment value of the resistance assembly is controlled through the first channel, so that the resistance adjustment reaction can be more real-time and rapid. When the output power and the set power value are inconsistent, the resistance adjustment control can be quickly performed. Since the resistance adjustment value of the resistance assembly corresponding to the difference value needs a certain operation time, the time delay of adjusting the resistance of the resistance assembly will be generated, so it is difficult to ensure the timeliness of the resistance adjustment reaction. The time of adjusting the resistance of the resistance assembly through the unit resistance adjustment value can give the operation time of the resistance adjustment value of the resistance assembly corresponding to the difference value, and can avoid the situation that the resistance is adjusted. The sudden decrease or increase of the resistance will cause the discomfort of the driving end resistance.

[0075] The adjustment unit comprises:

[0076] The first data processing unit is configured to set a home point between the controller and the first channel, wherein the first channel comprises a positive channel and a negative channel;

[0077] The second data processing unit is configured to identify the difference value based on the home point. If the difference value is a complementary power, the positive channel is triggered to transmit a transmission trigger instruction to the resistance assembly. If the difference value is an excess power, the negative channel is triggered to transmit a transmission trigger instruction to the resistance assembly.

[0078] The first trigger unit is configured to start a unit resistance increase adjustment value when the resistance assembly receives the trigger instruction through the positive channel. The resistance assembly starts a unit resistance decrease adjustment value when the resistance assembly receives the trigger instruction through the negative channel.

[0079] The second trigger unit is configured to set a home box on the second channel, define a home box marking parameter, associate the home box with the function of the resistance assembly, extract parameter data from the resistance adjustment value of the resistance assembly corresponding to the difference value (here, the data extraction is the effective data in the resistance adjustment value of the resistance assembly corresponding to the difference value. The resistance adjustment value of the resistance assembly corresponding to the difference value is used to control the resistance adjustment of the resistance assembly. The resistance adjustment of the resistance assembly is realized by the current value, so the resistance adjustment value of the resistance assembly corresponding to the difference value can be converted into the current value corresponding to the resistance of the resistance assembly for transmission), and the parameter data corresponding to the parameter definition is placed in the home box and transmitted through the second channel. The resistance assembly receives the home box, and based on the association between the home box and the function of the resistance assembly, the parameter data is loaded on the resistance assembly for operation.

[0080] It should be noted that the first channel setting home point is to distinguish whether the difference value corresponds to the starting unit resistance increase adjustment value or the unit resistance reduction adjustment value. After the resistance component receives the instruction, it does not need to judge the data, and directly obtains the unit resistance increase adjustment value or the unit resistance reduction adjustment value according to the positive channel and the negative channel. The trigger instruction here is only a data transmission in the positive channel and the negative channel, and what the trigger instruction content is does not matter. The purpose is to transmit quickly with small data amount. When the resistance component receives the trigger instruction through the positive channel, the unit resistance increase adjustment value is started. When the resistance component receives the trigger instruction through the negative channel, the unit resistance reduction adjustment value is started. The second channel is provided with a home box, and the parameter definition corresponding to the home box is defined. The function of the home box and the resistance component is associated. The parameter data of the resistance adjustment value corresponding to the difference value is extracted to obtain the parameter data. The parameter data corresponding to the parameter definition is transmitted through the second channel by the home box. The resistance component receives the home box, and based on the association between the function of the home box and the resistance component, the parameter data is loaded on the resistance component for operation. There are infinite home boxes between the controller and the controller on the second channel. The function of the home box and the resistance component is associated. The home box has multiple box bodies, which can be used to load different parameter data such as voltage, current and the like. The function of the home box and the resistance component is associated. The function of the resistance component is the component adjustment of 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 be processed 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 reaction ability of the resistance adjustment are improved, and the output power adjustment is more consistent with the set power value.

[0081] The resistance adjustment module comprises a generator and an electronic load.

[0082] It should be noted that the electronic load connected with the generator is changed, so as to control the current in the generator circuit, and then the torque provided by the system to the outside can be changed, so that the system power is close to the set power. The driving wheel is a power input end. The driving wheel is provided with a driving wheel belt pulley on one side of the wheel shaft. The driving wheel is provided with a speed sensor on one side.

The rotating shaft of the generator is provided with a resistance component belt pulley. The resistance component belt pulley and the torque sensor belt pulley are connected through a transmission belt. One side of the transmission belt is provided with a belt tensioner.

[0084] Embodiment 2: The set module, the acquisition module, the data comparison module and the control module are the same as those in embodiment 1, and the difference lies in that the resistance adjusting module is composed of a flywheel and an eddy current electromagnet, and the way of adjusting the resistance size given by the control module is replaced by: adjusting the current flowing into the eddy current electromagnet to change the magnetic force of the eddy current electromagnet to adjust the resistance of the flywheel, so that the resistance of the flywheel changes, and then the resistance provided by the system to the outside can be controlled, so that the system power tends to the set power value.

[0085] It should be noted that the current flowing into the eddy current electromagnet is adjusted to change the magnetic force of the eddy current electromagnet to adjust the resistance of the flywheel, so that the resistance of the flywheel changes, and then the resistance provided by the system to the outside can be controlled, so that the system power tends to the set power value. The driving wheel is a power input end, the driving wheel pulley is further arranged on the wheel shaft on one side of the driving wheel, the torque sensor is located between the driving wheel and the resistance control assembly, the torque sensor sprocket is arranged on one end of the rotating shaft of the torque sensor, the torque sensor pulley is arranged on the other end of the rotating shaft of the torque sensor, the torque sensor sprocket and the driving wheel are connected through the chain, and the rotating speed sensor device is connected with the driving wheel through the transmission belt at the same time. The resistance control assembly comprises a flywheel and an eddy current electromagnet, the resistance assembly pulley is arranged on one end of the rotating shaft of the flywheel, the resistance assembly pulley and the torque sensor pulley are connected through the transmission belt, and the transmission belt is provided with a belt pressing wheel on one side.

[0086] The embodiment is used as follows: the driving wheel drives the torque sensor to rotate through the chain, the torque sensor drives the flywheel to rotate through the torque sensor pulley, the transmission belt and the resistance assembly pulley, the controller receives the torque T and the rotating speed V detected by the torque sensor and the rotating speed sensor, calculates the real-time motion power P according to the formula P=V×T, compares the real-time motion power P with the set power value of the power car, adjusts the current flowing into the eddy current electromagnet by the controller to change the magnetic force of the eddy current electromagnet, thereby adjusts the resistance of the flywheel, so that the resistance of the flywheel changes, and then the resistance provided by the system to the outside 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 realized.

[0087] The setting module, the acquisition module, the data comparison module and the control module in embodiment 3 are the same as those in embodiment 1, and the difference lies in that the resistance adjusting module is composed of a flywheel and a permanent magnet under the control of a servo mechanism, and the way of adjusting 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 system to the outside is changed, and the system power tends to the set power value;

[0088] It should be noted that the servo mechanism is adjusted to adjust 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 assembly is a flywheel and a permanent magnet, one side of the permanent magnet is provided with a servo mechanism, the servo mechanism is installed on the resistance control assembly base, the rotating shaft of the servo mechanism is connected with the lower end side surface of the permanent magnet, and the speed measuring device is a rotating speed sensor, which is installed behind the flywheel.

[0089] When the embodiment is used, the torque sensor measures the output torque value, at the same time, the speed measuring device is connected with the flywheel, and the rotating speed of the flywheel is measured. The rotating speed of the driving wheel can be obtained through the transmission ratio between the driving wheel and the flywheel, and the real-time motion power is calculated according to the formula P=VxT. Because the permanent magnet can generate resistance to the flywheel through the eddy current effect, the servo mechanism is adjusted to adjust the distance between the permanent magnet and the flywheel, so that the resistance of the flywheel is adjusted, and the resistance of the flywheel is changed, so that the resistance provided by the system to the outside is controlled, and the system power tends to the set power value, the power of the power car is kept stable, and the constant power fitness is realized.

[0090] The setting module, the data comparison module, the control module and the resistance adjusting module in embodiment 4 are the same as those in embodiment 1, and the difference lies in that:

[0091] The acquisition module adopts a data acquisition module, which is used to acquire the output voltage of the generator and the current in the generator to obtain the output power value of the generator, and the output power value of the generator is calculated by the controller based on the output power of the generator;

[0092] It should be noted that the object of the output pressure needs to be determined when the output power value is obtained. The object here is the driving end, and a corresponding data acquisition module is arranged on the driving end to acquire the output voltage and current of the generator driven by the driving end, and the output power of the generator is calculated. The calculation formula of the output power value of the generator is: I, U is the current output voltage of the generator, I is the current output current value, For output power value, the output power of the generator is transmitted to the controller and the output power value of the driving end is calculated, the power value corresponding to the current driving end can be obtained, the above conclusion is in the ideal case, the generator efficiency and mechanical transmission loss will affect the power accuracy in the actual case, in order to eliminate the above situation, the correction coefficient K can be introduced, the correction coefficient can eliminate the system loss and make the output power value close to the actual power value; The correction coefficient is a series of data obtained from the empirical value under different rotating speed and different power.

[0093] The electronic load connected with the generator is changed, so as to control the current in the generator circuit, and then the power provided by the system to the outside can be changed, so that the system power is close to the set power. The driving wheel of the resistance control assembly is a power input end. The driving wheel and the resistance control assembly are connected through an intermediate transmission shaft. One end of the intermediate transmission shaft is provided with a chain wheel, and the other end is provided with a belt wheel. The chain wheel and the driving wheel are connected through a chain.

The resistance component belt wheel and the intermediate transmission shaft belt wheel are connected through a transmission belt. One side of the transmission belt is provided with a belt pressing wheel.

[0094] When the embodiment is used: the driving wheel drives the generator to rotate through the intermediate transmission shaft. The data acquisition and construction module acquires the output voltage of the generator and the current in the generator. According to the formula I, the real-time motion power P is calculated and compared with the set power value of the power car. The controller adjusts the size of the electronic load, so as to adjust the current in the generator circuit, thereby adjusting the output power provided by the generator.

[0097] The acquisition module comprises a data acquisition and construction module. The data acquisition and construction module is connected with the setting module and is used for acquiring the output voltage of the generator and the current in the generator to obtain the output power value. An adjustment model is constructed based on the output power value. The driving end herein includes the crank, the driving wheel and the sprocket and other driving components on the bicycle;

[0098] The data comparison module is connected with the setting module and the acquisition module and is used for comparing the output power value with the set power value to obtain a difference value. The difference value includes that the output power value is less than the set power value and that the output power value is greater than the set power value;

[0099] The control module is connected with the data comparison module, and is used for controlling the resistance assembly to increase the resistance if the output power value is less than the set power value, and controlling the resistance assembly to decrease the resistance if the output power value is greater than the set power value, so as to make the output power value approach the set power value through the resistance adjustment of the resistance assembly.

[0100] The resistance adjustment module is connected with the control module, and is used for adjusting the resistance according to the value given by the control module.

[0101] The set module comprises:

[0102] The collection registration module is used for determining the set power value.

[0103] The set module is used for transmitting the set power value to the controller storage.

[0104] It should be noted that the user information is collected, and the user information includes basic information such as the name and age of the user. The user end is registered based on the user information, the set power value is determined based on the user end, and the set power value is transmitted to the controller storage, so that the energy required by the user can be determined.

[0105] The data collection and construction module comprises:

[0106] The set storage surface is provided with a grid, the power value is marked on the grid to obtain a data surface, and the set power value is marked on the data surface for positioning.

[0107] The output power value is calculated by collecting the output voltage of the generator and the current in the generator.

[0108] The output power value is marked on the data surface for positioning.

[0109] The set power value trend line is planned on the grid, and the set power value trend line is set based on the power value on the grid.

[0110] The output power value is collected in real time, the output power trend line is planned on the grid based on the output power value, the region output power trend line is obtained by regionally limiting the output power trend line according to the grid, and a plurality of region ports are set on the data surface, wherein the region port is composed of a plurality of sub-contact points.

[0111] Corresponding features are respectively assigned to the plurality of sub-contact points.

[0112] The data comparison module comprises: the corresponding region port is enabled based on the region output power trend line, and the plurality of sub-contact points in the region port are respectively connected with the region output power trend line and the set power value trend line through the features.

[0113] The region output power trend line is obtained by region limiting the output power trend line according to the preset power value range, and a corresponding region port is configured for the region output power trend line;

[0114] The region output power trend line is obtained by region limiting the output power trend line according to the preset power value range, and a corresponding region port is configured for the region output power trend line;

[0115] The region output power trend line is obtained by region limiting the output power trend line according to the preset power value range, and a corresponding region port is configured for the region output power trend line;

[0116] The region output power trend line is obtained by region limiting the output power trend line according to the preset power value range, and a corresponding region port is configured for the region output power trend line;

[0117] It should be noted that through the power setting and layout binding algorithm, the function is responsible for binding the user-set power value to the specified position of the data layout, ensuring intuitive display and subsequent application of the set power value.

[0118] Through the function of the generator data acquisition algorithm, the output voltage and current of the generator are collected in real time, and 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 a hardware interface or a sensor, ensuring the accuracy and real-time nature of the data.

[0119] The function of the output power calculation algorithm is described as calculating the output power of the generator according to the collected voltage and current values. The core operation is to apply the power calculation formula (such as P=UI) to calculate the output power.

[0120] 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 layout rules.

[0121] The function of the power correspondence analysis and adjustment algorithm is to analyze the correspondence between the set power value and the output power, and adjust the output power based on the analysis results to make it as close as possible to the set power value. The core operation includes an analysis phase, a comparison of the difference between the set power value and the output power, and an evaluation of whether adjustment is needed; an adjustment phase, in which the output power is adjusted by controlling the working state of the generator (such as adjusting the load, optimizing the power generation efficiency, etc.) according to the size and direction of the difference; and a feedback loop, in which the adjusted output power is continuously monitored until it meets the predetermined conditions (such as within the error range) with the set power value. The set data plane is used to mark the set power value for positioning, which is to bind the set power value on the data plane. The output voltage and current of the generator are then collected to calculate the output power value, which is also marked on the data plane for positioning. The correspondence between the output power value and the set power value on the data plane is used to ensure the adjustment of the output power value. A two-dimensional plane is defined as the storage plane for power data. This storage plane is a flat storage layout, which is divided into multiple small grids (such as square or rectangular grids) for storing the power value at that location. A two-dimensional array or matrix is used to represent the grid, with each element of the array corresponding to a grid and storing the power value of that grid. A series of paths are then planned on the grid. The output power is collected in real time to plan the output power path in real time, which represents the flow direction of the power. This includes the set power value path and the output power path, which can be directly distinguished from the set power value path and used for subsequent adjustment of the output power path. Path planning algorithms (such as Dijkstra's algorithm) in graph theory are used to plan the power path. Instead of planning the complete output power path first and then limiting the area, the output power value is collected in real time while planning the output power path and limiting the area according to the pre-set power value range. The output power value is collected in real time and the output power path is planned. The output power value is obtained in real time by sensors or other devices. The output power path is planned based on the real-time collected power value on the grid. The output power path is divided into multiple regions according to the grid, and the output power path of each region is obtained. Dynamic programming or greedy algorithm is used to adjust the flow path of the output power in real time.When dividing the regions, the region boundaries can be defined according to the coordinates of the grid or the distribution of the power values, and then the correspondence between the power trend lines of each region and the region ports is established. When the output power flows to a certain region, the ports of the region are enabled according to the correspondence. A hash table or a dictionary is used to store the correspondence between the regions and the ports. When the output power enters a certain region, the corresponding ports are enabled by looking up the correspondence. The region port enabling feature is set and the output power value is located. The region port enabling feature is the difference power value between the enabled output power and the set power value. In actual use, data visualization techniques such as heat maps and contour maps can be used to show the distribution of the output power value on the data page. The data page is updated in real time to reflect the enabling state of the region ports and the change of the output power value, which can facilitate subsequent quick adjustment of the resistance of the resistance assembly by the generator, faster response to resistance adjustment, and more stable and fast process of adjusting the resistance of the resistance assembly. Initialize a set A containing multiple region ports, and maintain a sub-contact list inside each region port. Traverse the sub-contacts of each region port, and assign features to each sub-contact according to business requirements. These features include reference features for identifying and connecting to the region output power trend lines corresponding to the sub-contacts and serving as set power value trend lines for adjusting and verifying power values. Connect with the region output power trend lines and the set power value trend lines respectively. When the region output power trend line has data flow, the corresponding region port enabling logic can be triggered by looking up and matching the feature identifiers. The difference data can be accurately and quickly obtained in the subsequent data page, and the generator can be adjusted in real time through the region ports to ensure that the corresponding ports can be quickly enabled to obtain data values and transmit the obtained difference power values to the resistance assembly for adjusting the current of the resistance assembly, so that the resistance assembly obtains the corresponding set power value output power under the adjustment of the current and the 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.

[0122] According to the preset power value range, the interval division algorithm is adopted (here, the preset power value range is adopted) to finely segment the output power trend line, and a plurality of independent output power trend lines are generated; each region is allocated a specific port, and the port 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 plurality of output power trend lines, the mapping matching algorithm (such as nearest neighbor matching, linear interpolation matching, etc.) is adopted to correspondingly divide the set power value trend line (here, the corresponding division standard can be time, grid marking power value, and space with time marking; the starting time of the generator in operation is marked on the space with time marking; the output power value is collected in real time and marked on the data sheet and constructed into an output power trend line; the port is preset on the data sheet; 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 in the preset power value range, the corresponding regional port function ends, and 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; the corresponding regional port no longer works when the regional output power trend line ends). A plurality of set power value trend lines are formed. Through the binding algorithm (such as key-value pair binding, index binding, etc.), each regional output power trend line is bound with its corresponding regional set power value trend line, and the 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, through the hash table or array index method, each regional port is bound with the corresponding regional set power value trend line, and the explicit corresponding relationship between the regional port and the set power value trend line is established; the 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. Through the difference calculation algorithm (such as direct subtraction, weighted difference calculation, etc.), the difference value is calculated and updated in real time, so that the system can adjust or optimize the power distribution strategy accordingly, and the corresponding port can be quickly enabled to acquire data values 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 corresponding set power value output power 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.

[0123] The sub-touch points are respectively monitoring the region output power trend line and the set power value trend line, and are used to obtain data on the region output power trend line and the set power value trend line. When the data on the region output power trend line and the set power value trend line is obtained in real time, the sub-touch points move along the region output power trend line and the set power value trend line 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-touch points on the region output power trend line and the set power value trend line are communicatively connected. The sub-touch points are communicatively connected according to time. The communicatively connected sub-touch points correspond to each other one by one on the region output power trend line and the set power value trend line. Then, the data obtained by the sub-touch points on the region output power trend line and the set power value trend line is calculated to obtain the region port enabling feature. The region port enabling feature can be used for subsequent comparison while collecting the region output power trend line and obtaining the control information for adjusting the generator current, so as to realize the purpose of fast and real-time adjustment.

[0124] The control module comprises:

[0125] The connection relationship between all the region ports and the generator is established.

[0126] The region port enabling feature is transmitted to the generator through the corresponding region port to adjust the current of the generator. If the region port enabling feature is negative, the current of the generator is increased. If the region port enabling feature is positive, the current of the generator is decreased, until the output power value of the generator is the same as the set power value.

[0127] It should be noted that all the region ports and the generator have a communicatively connected relationship. When the output power trend line constructed by the output power value develops to a certain region output power trend line, the corresponding region port is enabled, and the other region ports are in a closed state. The corresponding region port is responsible for the corresponding region output power trend line. Then, the region port enabling feature obtained by the data page is transmitted to the generator to adjust the current of the generator, until the output power value of the generator is the same as the set power value. The region port enabling feature is obtained by the data collected by the sub-touch points.

[0128] In embodiment 5, the resistance adjustment module adjusts the resistance size according to the value given by the control module in the following way: changing the electronic load connected to the generator, controlling the current in the generator loop, and making the output power of the generator tend to the set power value.

[0129] It should be noted that the electronic load connected with the generator can be changed to control the current in the generator circuit, so that the output power P=U×I of the generator tends to the set power value, and constant power fitness is achieved; when the output power of the generator is the same as the set power value, the power value of the resistance assembly driven by the generator is also the same as the set power value.

[0130] The above merely provides a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
