[0030]As shown in FIG. 1, the embodiments of the present disclosure provide a smart fitness system, which includes a smart fitness device 1 having a hardware structure. The smart fitness device 1 may be selectively attached to a fitness equipment, and the smart fitness device 1 may actively obtain an attached state.

[0031]The smart fitness device 1 is provided with a sensor for monitoring the attached state. The sensor may include one or more of a magnetometer sensor, a pressure sensor, a contact electrode induction sensor, an infrared sensor, an ultrasonic sensor, and a position sensor. Alternatively, the sensor may be one or more of a touch switch, a proximity switch, and a photoelectric switch. No specific restrictions are made to the sensor.

[0032]The attachment method of the smart fitness device 1 to the fitness equipment includes one or more of adsorbing (magnetic, vacuum, static electricity), binding, hanging, and clamping. No specific restrictions are made to the attachment method.

[0033]The smart fitness device 1 may obtain a movement state of the fitness equipment during use. The smart fitness device 1 is provided with a data acquisition sensor. The data acquisition sensor includes one or more of an accelerometer, a gyroscope, and a magnetometer. No specific restrictions are made to the data acquisition sensor.

[0034]As shown in FIG. 2, the smart fitness device 1 may establish a connection with a data terminal 2 and send a collected movement state to the data terminal 2. The data terminal 2 includes software and/or hardware. The data terminal 2 may be configured on an operating device, such as a smart phone, a computer, a tablet, etc., with no specific restrictions. The smart fitness device 1 may establish a connection with the data terminal 2 through wireless data transmission, such as Bluetooth, WIFI, mobile communication technology, Star Flash, etc., and no specific restrictions are made here. The smart fitness device 1 is provided with a corresponding wireless networking module, so as to establish a connection with the data terminal 2 and realize data transmission.

[0035]The smart fitness device 1 has a built-in battery for normal operation of the components therein, and the type of battery is not specifically limited here.

[0036]In some embodiments, a smart fitness system includes a smart fitness device 1 and a data terminal 2. After the smart fitness device 1 is turned on, it actively establishes a connection with the data terminal 2. Here, the data terminal 2 is configured on a mobile phone in the form of a terminal APP (application). After the smart fitness device 1 and the mobile phone are paired through Bluetooth, a data connection is established. A user may select a fitness equipment as needed, and then attach the smart fitness device 1 to the fitness equipment. The sensor of the smart fitness device 1 may monitor the attachment status. Upon receiving a monitoring signal indicating that the attachment is complete, the smart fitness device 1 sends a completion signal to the mobile phone.

[0037]The terminal APP is configured to manage the accessed smart fitness device 1, obtain the movement state collected by the smart fitness device 1, analyze the movement state, store the movement state, etc. After receiving the completion signal from the smart fitness device 1, the terminal APP displays an interface for a user to enter the type, model, and various parameters of the fitness equipment to be matched.

[0038]Taking one fitness equipment as an example, a user is going to taking dumbbells for fitness training (the following embodiments are all explained with dumbbells as examples). The fitness equipment type entered by the user on the interface popped up by the terminal APP is dumbbells, the model is fixed weight, and the weight value is 2 Kg. Some prompt information is also given, for example, a “ready to start” interface may be popped up, giving the user a countdown time to get ready. When the “ready to start” interface ends, the training begins.

[0039]When the user starts training, the smart fitness device 1 collects the movement state in real time and sends the movement state to the data terminal 2 synchronously. The terminal APP analyzes the movement state and confirms the standardization of the movements. The standardization of the movements may be obtained through a comprehensive analysis of multiple technical parameters. The standards to be considered for each fitness equipment are not exactly the same, allowing differences in the corresponding technical parameters. Commonly adopted technical parameters include speed, amplitude, time, position, proficiency, etc. In addition, standardization may also be optionally combined with a training goal, such as fat loss, muscle gain, endurance, etc. The training goal is also the basic parameter for standardization judgment. In other words, other technical indicators and execution standards may be set in combination with the training goal. In addition, standardization may also be optionally combined with a training scene, such as home, gym, outdoor, etc., which is not limited here.

[0040]In some embodiments, the movement state is composed of a movement signal, and the movements signal includes an acceleration signal; and/or an angular movement signal; and/or a fusion signal of an acceleration signal and an angular movement signal.

[0041]The terminal APP constructs a movement trajectory based on the acquired movement state, and then matches the movement trajectory with a standard movement library. If the recognition is successful, the movement trajectory is recorded and a movement success information is fed back to the smart fitness device 1. If the recognition fails, the movement trajectory is recorded and a movement failure information is fed back to the smart fitness device 1.

[0042]In some embodiments, the smart fitness device 1 makes corresponding interactive responses based on the feedback information received from the data terminal 2. The interactive response includes one or more of light, sound, and vibration, and there is no specific restriction here. The user understands the performance of the training and make appropriate adjustments. For example, the smart fitness device 1 emits a green light when receiving the movement success information, and emits a flashing red light if receiving the movement failure information. The user may distinguish whether the movement is standard according to the color of the light, so as to adjust his/her movement and complete the training.

[0043]In addition, in some embodiments, the user may choose to stop training after receiving multiple prompts of movement failure information. The historical records are replayed on the data terminal 2 for understanding the reasons of the failed movements. Moreover, the system also provides standard movements for the user to make correct adjustments.

[0044]In some embodiments, a deep learning model such as a convolutional neural network (CNN) model and a long short-term memory (LSTM) model may be constructed to determine whether the movement meet the standard by analyzing and processing the movement trajectory. The deep learning model may be configured in the data terminal 2. In this way, a lightweight deep learning model is selected to reduce the hardware requirements of the data terminal 2.

[0045]In addition, as shown in FIG. 2, in some embodiments, the smart fitness system is also configured with a server 3 for movement recognition, which may be optionally set at a remote end. The smart fitness device 1 and/or the data terminal 2 establishes a connection with the server 3 through a network and realizes data transmission. The server 3 identifies the received movement state and/or movement trajectory, and feeds back the identification result to the smart fitness device 1 and/or the data terminal 2. The server 3 is optionally configured with a higher-level deep learning model. Compared with the data terminal 2, the server 3 has stronger computing power to process the training data uploaded by multiple users, and also stores the data. By aggregating the training data of different users, the server 3 may further modify the movement recognition, train the deep learning model, and improve the overall performance of the system.

[0046]For the user's movements during training, the data terminal 2 gives standard movements according to the fitness equipment type, training goals, and personal physical fitness, which may be watched by the user before starting the training. In some embodiments, the system helps the user standardize his/her movements based on historical records. For example, the system analyzes the user's movement trajectory and makes a comprehensive analysis, determines which movements are suitable for the user, and dynamically adjust the difficulty coefficient of the movements. There is no specific restriction here.

[0047]In some embodiments, some movements are usually reciprocating training, or understood as reciprocating execution of a movement. Usually, a movement has an initial position and an end position. Alternatively, a movement has an initial position, at least one intermediate position and an end position. Alternatively, a movement has an initial position, at least one intermediate position, with or without the end position. Alternatively, a movement has at least one intermediate position, one end position, with or without the initial position; or at least one intermediate position, with or without the initial position and the end position. The system matches the corresponding movements according to the selected equipment, training goals and personal physical fitness. The data terminal 2 obtains the data collected by the smart fitness device 1 in real time to construct a movement trajectory, analyzes the movement trajectory according to a necessary position required for a movement, and whether the movement is successful by determining whether the movement meets the necessary conditions. The trajectory characteristics of a single action may include linear, curved, or a multi-segmented form, without specific limitations.

[0048]The movement trajectory of each movement may be output as a waveform on a time axis. The waveform includes several peaks and valleys. The waveform may be segmented using peak segmentation, valley segmentation, or center point segmentation to form multiple segments, with each segment representing a single action trajectory. The segmentation method may be selected based on necessary positions required for the movements. The success of a single action trajectory may be determined through comparison, and optionally, the degree of error may also be selected.

[0049]In some embodiments, the necessary position is not a fixed value, but has a range with a tolerance. The movements within the position tolerance are understood as correct movements. The position tolerance may be dynamically adjusted or set to a fixed value according to the type of equipment, training goals, personal physical fitness, environment, etc.

[0050]Due to reasonable amplitude variations of the movements caused by differences among users, such as height, total arm length, upper arm length, forearm length, total leg length, thigh length, calf length, weight, age, gender, etc. Therefore, in some embodiments, the system requires the user to input personal physical information at the initial stage of use. Personal information is considered private, which the user may choose to enter. Moreover, the system optionally encrypts the recorded data, without displaying it in plain text. When analyzing the movement trajectory, the system incorporates the personal physical information for personality analysis to produce a more accurate result.

[0051]Moreover, the system may optionally give a personalized training plan based on the physical information. For example, the system may access an AI model, and may generate standard or relatively standard movement tutorials based on physical information, which may be presented to the user in the form of pictures, videos, voice, etc.

[0052]In some embodiments, the system scores the movements according to the acquired movement state and gives optimization suggestions based on the score. The user may intuitively assess the correctness of the movements based on score, allowing to quantify training effectiveness and adjust training goals according to the user's level of acceptance.

[0053]In some embodiments, the data terminal 2 may also access other data acquisition terminals, including wearable devices, image perception devices, environmental perception devices, etc. The data terminal 2 may integrate the data provided by the acquisition terminal for further comprehensive analysis. For example, the user's blood pressure, heart rate, respiratory rate, body temperature, etc. are integrated. The training goals are dynamically adjusted according to the results of the comprehensive analysis. For example, the user's fatigue level during training may be evaluated to adjust the training time, the training intensity, the interval duration of each group, the daily training goal, etc.

[0054]In some embodiments, the system may optionally or regularly generate a training report with charts and data comparisons to help the user to understand the effectiveness of training. The system may also give suggestions based on historical training records, including the user's strengths, weaknesses, and areas for improvement, etc. The system may identify aspects where the user excels, areas of disadvantage, and opportunities for enhancement, etc. The system may generate analysis reports, data reports, etc., which the user may share with coaches for further analysis.

[0055]In some embodiments, the system may also access a voice system, and the data terminal 2 and/or the smart fitness device 1 may send and receive voice content. The user may communicate with the system in real time via voice to understand the training status, which includes equipment selection, parameter settings, training goals, rest intervals, time management, and the completion of exercises, etc.

[0056]As shown in FIG. 3, the embodiments of the present disclosure propose a smart fitness device 1, which includes an attachment structure 11 for attaching to a fitness equipment.

The smart fitness device 1 sends a trigger signal to the data terminal 2 to confirm one of the operations during the training process.

[0063]As shown in FIG. 4, in some embodiments, the smart fitness device includes a third sensor 127 for obtaining environmental information, and the third sensor 127 is electrically connected to the processor 121.

[0064]As shown in FIG. 4, in some embodiments, the smart fitness device includes a feedback module 128 for feedback of a movement status, and the feedback module 128 is electrically connected to the processor 121. The feedback module 128 includes one or more of light, sound, and vibration, which is not specifically limited. The data terminal 2 or server 3 analyzes the movement status uploaded by the smart fitness device 1, and optionally feeds back the analysis results to the smart fitness device 1. The smart fitness device 1 responds accordingly to the feedback results so that the user may understand and adjust the training movements. Alternatively, different responses bring different experiences to the user, thus adjusting the atmosphere during training.

[0065]In some embodiments, the above sensors all include a low power consumption mode, which automatically reduces power consumption when the user is at rest or inactive, thereby extending the battery life of the device.

[0101]As shown in FIG. 24, the embodiments of the present disclosure propose an intelligent fitness method, applied to a smart fitness system, which includes the followings steps.

[0102]S10, attaching a fitness equipment and triggering a start signal.

[0103]The smart fitness device is attached to a fitness equipment and sends a start signal to a data terminal and/or a server.

[0104]S11, obtaining a movement state.

[0105]The smart fitness device obtains the movement signal during the training process in real time and forms a movement state for the data terminal and/or the server to analyze the movements. As shown in FIG. 17 to FIG. 23, in some application scenarios of the smart fitness device in accordance with the embodiments of the present disclosure, two or more half-ring structures are selectively attached to some fitness equipment, and each half-ring structure separately collects the movement state of the fitness equipment attached to it.

[0106]S12, obtaining a movement trajectory according to the movement state.

[0107]The data terminal and/or the server generate the movement trajectory based on the movement state over time. The movement trajectory is visualized as a waveform. If multiple half-ring structures are attached to the fitness equipment, the data terminal and/or the server may obtain a set of movement trajectories.

[0108]S13, comparing and analyzing the movement trajectory to confirm standardization of a movement.

[0109]The data terminal and/or the server analyze the movement trajectory by comparing with the standard movement library, and/or compare and analyze the movement trajectory through the deep learning model to determine the standardization of the movement. If one or more half-ring structures are attached to the fitness equipment, the data terminal and/or the server may make a comprehensive analysis of one or a group of movement trajectories, and then deduce the standardization of the user's movement. For example, as shown in FIG. 18, a half-ring structure is placed at both ends of the barbell, and the angle, inclination, speed, acceleration and other data collected by the two half-ring structures are configured to deduce whether the height and movement speed of the two ends of the barbell are consistent, thereby deriving the standardization of the user's movement.

[0110]As shown in FIG. 25, in some embodiments, S13, comparing and analyzing the movement trajectory to confirm standardization of the movement, including the following steps.

[0111]S131, processing the movement trajectory to obtain a single action trajectory.

[0112]The movement trajectory information is usually composed of a series of reciprocating actions. To compare the actions, it is necessary to analyze each action. Therefore, the movement trajectory needs to be decomposed to obtain a trajectory of a single action.

[0113]S132, comparing the single action trajectory to confirm the standardization of the movement.

[0114]The data terminal and/or the server compares and analyzes the single action trajectory through the standard movement library, and/or analyzes the single action trajectory through the deep learning model to determine the standardization of the movement.

[0115]In some embodiments, S131, processing the movement trajectory to obtain the single action trajectory, includes the following step.

[0116]The waveform includes several peaks and valleys, and the waveform may be segmented by peak segmentation, and/or valley segmentation, and/or center point segmentation to form multiple segments, each of which is a single action trajectory.

[0117]As shown in FIG. 26, the embodiments of the present disclosure propose an intelligent fitness method, which includes the following steps.

[0118]S20, inputting physical information.

[0119]The user's physical condition affects the position and amplitude of the movement. Therefore, the physical information may affect the analysis of the movement. The physical information is optional and not necessary. The physical information includes height, total arm length, upper arm length, forearm length, total leg length, thigh length, calf length, weight, age, gender, etc., and no specific restrictions are made here.

[0120]S21, attaching a fitness equipment and triggering a start signal.

[0121]S22, obtaining a movement state.

[0122]S23, obtaining a movement trajectory according to the movement state.

[0123]S24, processing the movement trajectory to obtain a single action trajectory.

[0124]S25, comparing the single action trajectory to confirm standardization of the movement.

[0125]As shown in FIG. 27 and FIG. 28, the embodiments of the present disclosure propose a smart fitness method, which includes the following steps.

[0126]The data terminal is installed with an APP, which prompts the user to enter his/her physical information upon first use. The physical information is considered personal privacy, and the user may choose not to input it. The system optionally encrypts the recorded data, and does not display it in plain text.

[0127]Then, the APP establishes a connection with the smart fitness device through the data terminal. When used the first time, the data terminal and the smart fitness device need to match each other. For example, if a Bluetooth connection is used, pairing is required before completing the network connection; and WIFI and NFC fast pairing are also supported, with no specific restrictions.

[0128]Before the training starts, a large model may be configured to generate a training plan. The large model proposes fitness equipment which are available and training goals based on the physical information. The training plan may include several sets of movements, the duration of each set of movements, the time interval between each set of movements, etc., and no specific restrictions are made here.

[0129]The smart fitness device is attached to the selected fitness equipment. After attachment, the first sensor of the smart fitness device is triggered, and the APP receives the trigger signal and pop up an inquiry message, which includes the type, other parameters (weight, tension, number of times, etc.) of the fitness equipment.

[0130]Then the training phase is started, the smart fitness device informs the user that the training starts with sound, light, etc.

[0131]As shown in FIG. 28, after starting training, the smart fitness device collects the data of every movement during the training process and sends the movement status to the APP. The APP recognizes the movements. If the movements are correct, the movement status is recorded and the correct result is fed back to the smart fitness device to determine whether the group of movements is completed. If the movements fail, the failed result is fed back to the smart fitness device. Failed movements may also be recorded for later analysis. An interval time is set between each group of movements, and the next group of movements is entered after rest.

[0132]After the previous group of training is completed, if the user needs to shift to another equipment, the smart fitness device may be attached to the other equipment. Then a new training cycle is entered, until the entire training plan is completed.

[0133]In addition, the user may also record his/her own movements and upload them to the cloud for manual verification and add them to the movement library. Fitness communities may be built in the cloud, and the uploaded movements may be labeled and verified by community members to enrich the standard movement library.

[0134]The above description is only some embodiments of the present disclosure and is not intended to limit the scope of the present disclosure. Any equivalent changes or modifications made according to the structure, characteristics and principles described in the protection scope of the present disclosure should be included in the protection scope of the present disclosure.
