Description

Technical Field

[0001] This invention relates to the field of combat training technology, specifically to a combat training cognitive enhancement system and its attention training method. Background Technology

[0002] Combat sports are high-intensity competitive activities that integrate technique, physical fitness, and mental fortitude. With the development of sports technology, modern combat training is no longer limited to traditional physical fitness and skill development, but is gradually evolving towards a synergistic development of physical and cognitive abilities. In intense combat, athletes need to maintain a high level of focus for extended periods (sustained attention) and be able to quickly filter relevant information and make decisions in complex and dynamic environments (selective attention).

[0003] Currently, traditional combat training mainly relies on fixed punching bags, hand targets, or coaching sparring partners. The evaluation of training effectiveness often depends on the coach's subjective experience, lacking quantitative assessment methods for athletes' cognitive states (such as concentration and reaction speed). Although some intelligent combat training devices with light-based cues have appeared on the market, existing technology has the following main shortcomings: Existing devices often blindly pursue high brightness or use highly saturated (such as pure red or strong flashing) warning colors to attract attention when designing visual interaction signals. Related visual cognition research shows that excessive brightness and highly arousing hues (such as red) can easily overstimulate the optic nerve, causing trainees to experience visual fatigue and psychological anxiety prematurely during prolonged exercise, thereby accelerating the depletion of attentional resources and making it impossible to maintain an optimal cognitive state during high-intensity training.

[0004] Most existing devices only provide training for responding to random light illumination, lacking training algorithms that differentiate between "continuous attention" and "selective attention." For example, they cannot simulate complex scenarios where users need to sift through a large amount of interference signals to find the target signal, resulting in training content that is out of touch with real-world cognitive needs.

[0005] Existing equipment focuses on recording the force or number of hits, lacking accurate statistics and real-time feedback on "reaction time (RT)" and "error rate (missed hits / mishit)," thus failing to form a complete profile of the athlete's cognitive abilities.

[0006] Therefore, there is an urgent need for a combat training cognitive enhancement system and its control method that can optimize visual interaction parameters, reduce cognitive load, and have specific attention training functions. Summary of the Invention

[0007] The purpose of this invention is to provide a cognitive enhancement system for combat training and its attention training method to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a combat training cognitive enhancement system, comprising a smart sandbag, a control terminal, and a display device; a visual interaction module is provided on the striking surface of the smart sandbag, the visual interaction module being used to emit light signals to indicate the striking target; the control terminal is electrically connected to the visual interaction module and the display device respectively, the control terminal being configured to control the luminous hue and luminous brightness of the visual interaction module, and to receive feedback signals generated by the smart sandbag when it is struck; the display device is used to display training evaluation data according to the feedback signals.

[0009] Preferably, the visual interaction module includes a plurality of LED light-emitting units arranged in an array or distributed circumferentially on the surface of the smart sandbag, wherein the LED light-emitting units are embedded in the skin of the smart sandbag or cover the skin of the smart sandbag.

[0010] Preferably, the control terminal has a preset low-load visual parameter mode. In the low-load visual parameter mode, the control terminal is configured to set the reference luminous color of the visual interaction module to blue and set the luminous brightness to a low brightness threshold. The low brightness threshold is 50% of the maximum brightness of the visual interaction module.

[0011] Preferably, the smart sandbag is equipped with a sensing module inside, which is used to detect the striking action and generate the feedback signal; the sensing module includes at least one of an acceleration sensor, a pressure sensor, or a vibration sensor.

[0012] Preferably, the control terminal is further configured with a continuous attention training mode and a selective attention training mode; in the continuous attention training mode, the control terminal controls the visual interaction module to flash at a preset random time interval; in the selective attention training mode, the control terminal controls the visual interaction module to simultaneously present a target light signal that conforms to the low-load visual parameter mode and an interference light signal that is different from the target light signal.

[0013] This invention also provides a control method for any of the above-mentioned combat training cognitive enhancement systems, characterized by comprising the following steps: S1: Initialize system parameters, set the reference luminous color of the visual interaction module to blue, and set the luminous brightness to 50% of the maximum brightness; S2: Generate corresponding control commands based on the training mode selected by the user to drive the visual interaction module to emit light signals; S3: Monitor the status of the sensing module of the smart sandbag in real time. If a feedback signal is received within a preset time window, record the moment of impact. S4: Calculate the reaction time based on the time of light signal emission and the time of impact, and calculate the error rate based on the correctness of the impact; S5: Send the calculated reaction time and error rate to the display device for display.

[0014] Preferably, in step S2, if the selected training mode is the continuous attention training mode, the generated control instruction logic is: control a single light-emitting unit to light up randomly, the lighting duration is a fixed value, and the time interval between two lighting events varies randomly within a preset range.

[0015] Preferably, in step S2, if the selected training mode is selective attention training mode, the generated control instruction logic is: control multiple light-emitting units to light up simultaneously, one of which displays a reference light-emitting color tone and low brightness as a target, and the remaining light-emitting units display an interference color tone or high brightness as interference targets.

[0016] Preferably, in step S4, the error rate calculation logic includes: if the feedback signal is not received within a preset effective time after the visual interaction module emits a light signal, it is recorded as a missed click error; if the feedback signal is received when the visual interaction module does not emit a light signal or emits an interfering light signal, it is recorded as a false click error; the system counts the number of missed click errors and the number of false click errors per unit time to generate error rate data.

[0017] Compared with the prior art, the beneficial effects of the present invention are: By setting a low-load visual parameter mode, the control terminal sets the reference luminous hue to blue and the brightness to 50% of the maximum brightness, effectively avoiding the excessive stimulation of the optic nerve by traditional high brightness or high arousal hues, reducing visual fatigue and cognitive load during training, thus enabling trainees to maintain a more sustained state of focus during high-intensity exercise.

[0018] By configuring continuous attention training mode and selective attention training mode, and utilizing random time interval flashing logic and target / interference signal mixing logic respectively, specific differentiated training of athletes' "ability to maintain focus" and "ability to select targets in complex environments" was achieved, solving the problem that the existing equipment's training mode is too singular and cannot meet the needs of professional cognitive training.

[0019] By setting up a sensing module and working with a display device, it can capture striking actions in real time and calculate millisecond-level reaction times as well as error rate data including missed strikes and mis-strikes. This transforms abstract cognitive abilities into intuitive quantitative indicators, making it easier for users to adjust their training plans in a timely manner based on data feedback.

[0020] By embedding or covering the LED light-emitting unit on the surface of the smart sandbag and setting the control terminal in the non-impact area or using a wireless connection, the system effectively prevents damage to the precision electronic control components caused by the vibration generated by high-intensity impacts while ensuring the flatness of the sandbag surface and the impact feel, thus extending the service life of the system. Attached Figure Description

[0021] Figure 1 This is a flowchart illustrating the control method of the present invention. Detailed Implementation

[0022] This invention provides a cognitive enhancement system for combat training, whose main hardware architecture includes a smart sandbag, a control terminal, and a display device. The smart sandbag, as the main execution component for training, has a visual interaction module on its striking surface. This module emits light signals to indicate the striking target. To address the problem of externally mounted targets easily detaching and affecting the striking feel in existing technologies, the visual interaction module in this embodiment adopts an embedded structure design. Specifically, the visual interaction module includes several LED light-emitting units arranged in an array (such as a 3×3 matrix) or evenly distributed circumferentially on the surface of the smart sandbag.

[0023] In terms of manufacturing process, the inner side of the smart sandbag's outer skin has a pre-drilled mounting groove. The LED light-emitting unit is encapsulated on a flexible circuit board and embedded in the mounting groove, or directly covered in the outer skin layer of the smart sandbag. The outside of the LED light-emitting unit is covered with an impact-resistant transparent flexible protective layer (such as transparent TPU material), which keeps the surface of the sandbag flat and smooth, allowing for clear transmission of light signals while preventing damage to the light-emitting element from high-intensity impacts.

[0024] A sensing module is located at the core of the smart sandbag to detect impacts and generate feedback signals. To accurately capture the moment of impact and distinguish between valid impacts and accidental touches, the sensing module is preferably installed on the central support column inside the smart sandbag or deep within the filling layer. The sensing module includes at least one of an accelerometer, a pressure sensor, or a vibration sensor. When the sandbag surface is impacted by an external force, the vibration wave is transmitted to the sensing module, which converts it into an electrical signal and sends it to the control terminal.

[0025] The control terminal is electrically connected to both the visual interaction module and the display device. As the system's computational core, the control terminal is configured to control the light emission color and brightness of the visual interaction module and receive feedback signals generated when the smart sandbag is struck. To achieve a low-load cognitive training environment, the control terminal has a preset low-load visual parameter mode. In this mode, the control terminal is configured to forcibly set the baseline light emission color of the visual interaction module to blue and set the brightness to a low brightness threshold, which is 50% of the maximum power brightness of the visual interaction module. This specific light parameter setting effectively reduces visual fatigue and psychological arousal levels in trainees. Furthermore, the control terminal is also equipped with a continuous attention training mode and a selective attention training mode to meet different cognitive training needs.

[0026] The display device is used to display training evaluation data based on feedback signals. It can be a wall-mounted display screen or a standing touch panel to present key indicators such as reaction time and error rate in real time, helping trainees to understand their own status immediately.

[0027] Based on the above hardware system, the present invention also provides a control method applied to the system, the method comprising the following steps: S1: Initialize system parameters.

[0028] After the system starts, the control terminal first executes the initialization program, which sets the reference luminous color of the visual interaction module to blue and the luminous brightness to 50% of the maximum brightness.

[0029] This step ensures that the underlying visual environment remains under low cognitive load regardless of the type of training, avoiding over-excitement or anxiety caused by bright or red light.

[0030] S2: Generate corresponding control commands based on the training mode selected by the user.

[0031] If the user selects the continuous attention training mode, the control command logic generated by the control terminal is as follows: control a single light-emitting unit to light up randomly, with a fixed duration (e.g., 250ms), and the time interval between two lights up randomly varying within a preset range (e.g., 900ms-1500ms). In this mode, the light signal is always blue and low-brightness, and the trainee needs to maintain long-term alertness to a single, appearing signal.

[0032] If the user selects the selective attention training mode, the control command logic generated by the control terminal is as follows: control multiple light-emitting units to light up simultaneously. Only one light-emitting unit displays a baseline light color (blue) and low brightness (50%) to serve as the target; the remaining light-emitting units display interfering colors (such as red or green) or high brightness (such as 100% brightness) to serve as interference targets. This mode requires the trainee to quickly select the correct target amidst strong visual interference.

[0033] S3: Real-time monitoring of the sensor module status of the smart sandbag.

[0034] Simultaneously with the emission of the light signal, the system begins timing and monitoring the sensing module. If a feedback signal is received within a preset time window (e.g., within 2 seconds of the signal being emitted), the system records the current moment of impact.

[0035] S4: Calculate reaction time and error rate.

[0036] The control terminal calculates the reaction time (RT) based on the time difference between the time the light signal is emitted and the time of impact. Simultaneously, it calculates the error rate based on the accuracy of the impact. The specific error rate calculation logic includes: Missed click error: If a feedback signal is not received within a preset effective time after the visual interaction module emits the target light signal, it is recorded as a missed click error. Accidental click error: If a feedback signal is received when the visual interaction module is not emitting a light signal (idle period) or is emitting an interfering light signal (selective mode), it is recorded as an accidental click error. The system counts the number of missed click errors and accidental click errors per unit time to generate comprehensive error rate data.

[0037] S5: Data feedback and display.

[0038] Finally, the control terminal sends the calculated reaction time and error rate to the display device for real-time display, forming a visualized training report.
