Description

Technical Field

[0001] This application relates to the field of information monitoring technology, specifically to a grip strength intelligent monitoring system, method, device, medium, and program product. Background Technology

[0002] Currently, the most common hand grippers on the market are mainly of two types: mechanical pointer type and basic electronic display type. The traditional mechanical pointer type hand gripper works by using spring deformation to drive the pointer to rotate. It can only display the value by sight, which has low accuracy and cannot record data. Although the basic electronic display type hand gripper can display the force value in real time, it cannot transmit data. It can only be displayed on the local machine and lacks data export and real-time synchronization functions. It cannot meet the needs of training data traceability, statistical analysis, remote viewing, etc.

[0003] The current technology has two major flaws: 1) The force data collected is not accurate enough. Factors such as hand tremors and differences in the duration of force application may affect the measurement of peak grip strength. The force data can only be displayed on the local machine and cannot be transmitted to the data source. Users cannot effectively utilize the data and cannot achieve systematic training management. 2) Existing wireless transmission solutions such as infrared and WIFI have obvious problems, such as poor adaptability and high energy consumption, which prevent long-term operation. No efficient data transmission solution for grip strength devices has been developed.

[0004] Therefore, there is a need for an intelligent grip force monitoring system that can accurately and effectively measure grip force, convert force values ​​into electrical signals in real time, and transmit them to a computer in a low-power, high-stability manner.

[0024] The following description, with reference to the accompanying drawings, illustrates some preferred embodiments of the present application. It should be noted that the following description is for illustrative purposes only and is not intended to limit the scope of protection of this application.

[0025] Figure 1 This is an exemplary block diagram of a grip strength intelligent monitoring system according to some embodiments of this application. See also: Figure 1 The intelligent grip strength monitoring system 100 may include a grip strength sensor 110, a force value acquisition module 120, a signal conditioning circuit 130, an analog-to-digital conversion module 140, a calibration module 150, a control module 160, a wireless communication module 170, and a terminal device 180. Detailed descriptions are provided below.

[0026] In some specific embodiments, the grip strengthener 110 adopts a conventional grip strengthener, which is described in detail in the prior art.

[0027] The force acquisition module 120 is located in the core force-receiving area of ​​the gripper and is used to convert the gripping force applied by the target object to the gripper into a corresponding analog electrical signal.

[0028] In some specific embodiments, the analog electrical signal is an analog voltage signal.

[0029] In some specific embodiments, the force acquisition module 120 includes a force sensor, which acquires force signals at a preset sampling frequency.

[0030] Specifically, the force acquisition module 120 can use a strain gauge force sensor, preferably a columnar elastomer structure sensor, and place the sensor in the core force-bearing area of ​​the gripper (such as the connection between the handle and the elastic pressure component) to ensure that the user's external force acts directly on the sensor elastomer, which is used to convert the grip force applied by the user into a corresponding analog electrical signal.

[0031] Furthermore, the electrical signal conversion principle of the grip strength device is as follows: when the user grips the grip strength device, the external force causes the sensor elastic body to undergo slight deformation, and the metal foil strain gauge attached to the surface of the elastic body will generate a change in resistance. The change in resistance is converted into a linear voltage signal through a Wheatstone bridge, and this voltage signal is proportional to the grip strength value.

[0032] The signal conditioning circuit 130 is electrically connected to the force acquisition module and is configured to amplify and filter the analog electrical signal before inputting it to the analog-to-digital conversion module.

[0033] In some specific embodiments, the analog electrical signal is amplified and filtered. For details, please refer to the prior art, which will not be elaborated here.

[0034] The analog-to-digital conversion module 140 is electrically connected to the signal conditioning circuit and is configured to convert analog electrical signals into digital force signals.

[0035] In some specific embodiments, the analog-to-digital conversion module can refer to the existing technology, and will not be described in detail here.

[0036] The calibration module 150 is electrically connected to the analog-to-digital conversion module and is configured to perform calibration processing on the digital force value signal to obtain the digital force value signal corresponding to the peak grip force value for each grip force action.

[0037] In some specific embodiments, during a complete grip force movement, the force signal output by the sensor exhibits a peak-shaped curve that rises and then falls over time, with its overall shape approximating a parabolic distribution. The peak grip force is calculated as the output grip force measurement result. To improve the stability and accuracy of the peak grip force calculation, the acquired digital force signal undergoes calibration processing. The calibration processing includes: S1 performs time-series analysis on continuously acquired digital force signals to identify complete signal segments corresponding to a single gripping action; S2, In the signal segment, identify the equilibrium segment located at the top of the wave crest, which corresponds to the brief holding phase of the target object under maximum force. S3, the data points corresponding to the balance segment are filtered out or their weights are reduced, and only the rising and falling segment signals on both sides of the peak are retained to calculate the peak grip force corresponding to a grip force action, which is used as the effective measurement result of the grip force value.

[0038] The embodiments of this application, through the above-described calibration process, can effectively reduce the impact of factors such as hand tremors and differences in the duration of force application on the calculation of peak grip strength, improve the repeatability and reliability of grip strength measurement results, and make the grip strength measurement results more accurate.

[0039] In this embodiment of the application, the analog voltage signal acquired by the force acquisition module is converted into a digital signal by the analog-to-digital converter (ADC) module. After being processed by the calibration module, the current grip force value can be displayed on the screen in real time.

[0040] The control module 160, electrically connected to the calibration module, is configured to perform data parsing, calibration compensation, and format encapsulation of digital force signals on the grip strength unit itself, generating force data frames for wireless transmission to reduce dependence on external devices and avoid additional delays introduced by multiple interactions; it filters key force data related to grip strength assessment, encapsulates and sends it, and reduces the transmission load of the wireless link by controlling the length of a single data frame and the transmission period, thereby shortening the processing delay from data acquisition to transmission, achieving continuous, low-latency transmission of force data, and avoiding display lag caused by wireless link congestion or batch transmission; and it controls the sampling timing of the analog-to-digital conversion module.

[0041] In some specific embodiments, the control module controls the force sensor to collect force signals at a preset sampling frequency.

[0042] Furthermore, the control module sends the force data to be transmitted to the wireless communication module via a serial interface or internal bus.

[0043] Specifically, in the data acquisition and processing stage, the control module acquires force signals at a preset sampling frequency and performs necessary data parsing, calibration compensation, and format encapsulation locally to reduce dependence on external devices and avoid additional delays introduced by multiple interactions. In the data organization and transmission stage, the control module only encapsulates and transmits key force data related to the current grip strength assessment. By controlling the length of a single data frame and the transmission cycle, the transmission load of the wireless link is reduced, thereby shortening the processing delay from data acquisition to transmission.

[0044] The embodiments of this application ensure the stability, real-time performance, and controllability of the force value monitoring and evaluation process through the multi-module collaborative working mechanism with the control module as the core.

[0045] The wireless communication module 170 is electrically connected to the control module and is configured to receive the force value data frame and send the force value data to an external terminal device in real time according to a preset communication protocol. The transmission timing and data update frequency of the wireless communication module are uniformly scheduled by the control module to ensure the continuity and real-time performance of data transmission.

[0046] Specifically, the control module sends the force value data frame to the wireless communication module, and the wireless communication module sends the force value data to the external terminal device in real time according to the preset communication protocol.

[0047] In some specific embodiments, the wireless communication module adopts low-power Bluetooth communication to balance real-time performance and power consumption control requirements; and by optimizing connection parameters and data transmission strategies, low-latency data transmission is achieved while ensuring controllable power consumption; the data transmission latency of the wireless transmission module is controlled within a preset time range to meet the requirements for real-time grip strength display.

[0048] In one embodiment, the data transmission delay is controlled within a preset time range to meet the needs of real-time display and evaluation of grip strength.

[0049] The wireless communication module in this embodiment employs Bluetooth Low Energy communication and achieves continuous, low-latency transmission of force data by controlling the data frame length and transmission rhythm, avoiding display lag caused by wireless link congestion or batch transmission. By optimizing connection parameters and data transmission strategies, low-latency data transmission is achieved while ensuring controllable power consumption.

[0050] The terminal device 180 is configured to decode and display the force value data immediately after receiving it, thereby realizing the real-time presentation of the grip force value and its changing trend.

[0051] Specifically, the terminal device can also send control commands to the control module via the wireless communication module to trigger calibration procedures, parameter updates, or test mode switching.

[0052] In some specific embodiments, the display and evaluation module of the terminal device can present the current grip strength value and its trend without waiting for the test to complete, and simultaneously support data storage and subsequent evaluation and analysis. The decoded grip strength value is used for functions such as real-time display, historical data recording, curve plotting, and evaluation and analysis.

[0053] In some specific embodiments, a calibration module 190 is also included, configured to generate calibration parameters, which are used to correct or compensate for digital force data after the analog-to-digital conversion module converts the analog electrical signal into a digital force signal; the calibration parameters are stored in the parameter storage area of ​​the control module.

[0054] Specifically, the calibration parameters include zero-point offset correction parameters obtained based on unloaded reference values ​​and error compensation parameters obtained based on reference force data. The unloaded reference value is the unloaded force data collected under no external force, and the reference force data consists of multiple preset sets of known force data. By collecting sensor force data corresponding to the known force data, error compensation parameters between the collected sensor force data and the reference force value are obtained. The error compensation parameters include linear compensation parameters and nonlinear compensation parameters obtained based on the known force data.

[0055] Furthermore, the calibration procedure for calibration module 190 includes the following steps: S1), Calibration Trigger: The system enters calibration mode when the hand gripper is used for the first time, when the environment changes, or when the user actively triggers a calibration command.

[0056] S2) Unloaded reference value data acquisition: When the user does not apply grip force, the digital signal output by the force sensor is collected as a no-load reference value to eliminate the influence of sensor zero-point offset and environmental noise.

[0057] Specifically, when the device is powered on or within a preset time interval, the sensor output signal under no external force is detected, and the zero-point offset is corrected to eliminate baseline drift caused by residual deformation of the elastomer or environmental changes.

[0058] S3) Preset reference force value data, and obtain error compensation parameters based on the reference force value data: The preset reference force data includes the user applying a known reference grip force according to the terminal software prompts, or performing a standardized grip action according to the preset reference force data; the system collects multiple sets of force data within a preset time window, and performs average or statistical processing on the data to obtain error compensation parameters.

[0059] In some specific examples, when the device leaves the factory or is used for the first time, at least two different standard force values ​​are applied to the gripper as reference force values, and corresponding sensor data is collected. The data is averaged or statistically processed to obtain error compensation parameters, such as establishing a mapping relationship between the sensor output signal and the actual grip force value, and obtaining the linear error and nonlinear error in the sensor data based on the deformation characteristics of the gripper elastomer.

[0060] S4) Calibration parameter generation: By integrating the unloaded reference value and error compensation parameters, calibration parameters are obtained for subsequent grip strength assessment. These calibration parameters are used to proportionally correct or offset the original force value data.

[0061] S5), Parameter Storage and Application: The generated calibration parameters are stored in the parameter storage area of ​​the control module and automatically recalled during subsequent grip strength data processing and evaluation, without requiring repeated user intervention.

[0062] In this embodiment, the corrected real-time grip strength value is obtained through the aforementioned calibration module and specific calibration scheme to improve measurement stability and consistency during long-term use; and is displayed in real time on the display screen. The aforementioned calibration module and specific calibration scheme effectively reduce measurement errors caused by sensor drift, individual differences, and long-term use, thereby improving the accuracy, stability, and repeatability of grip strength assessment results.

[0063] In summary, the embodiments of this application calibrate digital force data based on the calibration module, which can effectively reduce the impact of factors such as hand tremors and differences in the duration of force application on the calculation of peak grip strength, improve the repeatability and reliability of grip strength measurement results, and make grip strength measurement results more accurate. The control module performs data parsing, calibration compensation, and format encapsulation of digital force signals on the grip strength unit itself to generate force data frames for wireless transmission. This reduces reliance on external devices and avoids additional latency introduced by multiple interactions. Key force data related to grip strength assessment is selected, encapsulated, and sent. By controlling the length of each data frame and the transmission cycle, the transmission load on the wireless link is reduced, thereby shortening the processing latency from data acquisition to transmission. This enables continuous, low-latency transmission of force data and avoids display lag caused by wireless link congestion or batch transmission. The module also controls the sampling timing of the analog-to-digital conversion module. The wireless communication module operates under the control of the control module and is used to send the force value data to an external terminal device according to a preset communication protocol. The transmission timing and data update frequency of the wireless communication module are uniformly scheduled by the control module to ensure the continuity and real-time performance of data transmission. On the terminal device side, the received force data is decoded and used for real-time display, historical record, and subsequent evaluation and analysis; Through the above-mentioned multi-stage collaborative real-time guarantee scheme, real-time transmission and display of force data can be achieved in grip strength monitoring, effectively avoiding the problem of evaluation distortion caused by data delay; Through calibration modules and specific calibration schemes, measurement errors caused by sensor drift, individual differences, and long-term use can be effectively reduced, thereby improving the accuracy, stability, and repeatability of grip strength assessment results. Through the coordinated optimization of the above modules in data acquisition, processing, transmission and display, a real-time closed loop from the application of grip force to the presentation of monitoring results is achieved. Compared with the existing grip force detection schemes that only focus on the performance of a single module, this effectively improves the accuracy of grip force monitoring and the real-time transmission, and helps to improve the accuracy of grip force assessment.

[0064] This application provides a grip strength intelligent monitoring method 200 in some embodiments. The grip strength intelligent monitoring method 200 in this application includes: Step S1: Collect grip force data of the target object; The force acquisition module is set in the core force-receiving area of ​​the gripper and is used to convert the grip force applied by the target object to the gripper into a corresponding analog electrical signal; Step S2: Amplify and filter the analog electrical signal; Step S3: Convert the amplified and filtered analog electrical signal into a digital force signal; Step S4: Calibrate the digital force signal to obtain the digital force signal corresponding to the peak grip force value for each grip force action; Step S5: The digital force signal is parsed, calibrated, compensated, and formatted on the grip strength unit to generate a force data frame for wireless transmission. This reduces reliance on external devices and avoids additional delays caused by multiple interactions. Key force data related to grip strength assessment is selected, encapsulated, and sent. By controlling the length of each data frame and the transmission cycle, the transmission load of the wireless link is reduced, thereby shortening the processing delay from data acquisition to transmission. This achieves continuous, low-latency transmission of force data and avoids display lag caused by wireless link congestion or batch transmission. Step S6: The force value data is sent to the external terminal device in real time according to the preset communication protocol; the transmission timing of the force value data frame is uniformly scheduled with the data update frequency to ensure the continuity and real-time performance of data transmission. Step S7: After receiving the force value data, the terminal device immediately decodes and displays it, thereby realizing the real-time presentation of the grip force value and its changing trend.

[0065] In the embodiments of this application, the grip strength intelligent monitoring method can selectively incorporate features of the grip strength intelligent monitoring system, and vice versa.

[0066] In summary, by calibrating the digital force data, the embodiments of this application can effectively reduce the impact of factors such as hand tremors and differences in the duration of force application on the calculation of peak grip strength, improve the repeatability and reliability of grip strength measurement results, and make the grip strength measurement results more accurate. By parsing, calibrating, compensating, and encapsulating the digital force signal on the grip strength unit itself, force data frames for wireless transmission are generated to reduce dependence on external devices and avoid additional delays introduced by multiple interactions. Key force data related to grip strength assessment are selected, encapsulated, and sent. By controlling the length of a single data frame and the transmission cycle, the transmission load of the wireless link is reduced, thereby shortening the processing latency from data acquisition to transmission.

The force data is sent to an external terminal device according to a preset communication protocol; the sending timing and data update frequency are uniformly scheduled by the control module to ensure the continuity and real-time nature of data transmission. The received force data is decoded and used for real-time display, historical recording, and subsequent evaluation and analysis. Through the coordinated optimization of the above modules in data acquisition, processing, transmission and display, a real-time closed loop from the application of grip force to the presentation of monitoring results is achieved. Compared with the existing grip force detection schemes that only focus on the performance of a single module, this effectively improves the accuracy of grip force monitoring and the real-time transmission, and helps to improve the accuracy of grip force assessment.
