Description

Technical Field

[0001] The invention belongs to the technical field of short track speed skating, and in particular relates to a short track speed skating curve dynamic training simulation system and method. Background Art

[0002] Short track speed skating is an ice sport that emphasizes both speed and skill. Especially in terms of cornering technique, athletes need to master a series of skills while skating at high speeds to overcome strong centrifugal force to maintain balance and speed. The circumference of the short track speed skating track is 111.12 meters, of which the circumference of the curve is 53.42 meters and the radius of the curve is 8 meters. The curve occupies most of the track, which makes the competition of cornering technique crucial to winning. Cornering technique requires athletes to stretch their left and right legs asymmetrically at high frequency to obtain centripetal acceleration to maintain dynamic balance. Its training methods are mainly aimed at mastering its balance and the rationality of matching centripetal force with power. The current mainstream short track speed skating cornering training methods mainly include traction circling training method, static traction ice training method and land simulation training method.

[0003] The traction and circling training method uses a traction rope or elastic band fixed on one side, and the trainee is connected to it and practices cornering techniques by making circular motions on the ice. This training method can give athletes a real feel of the ice surface, but this method almost keeps the turning radius unchanged after entering the corner, and it is impossible to choose different turning routes, and it is impossible to adjust the appropriate turning angle and speed accordingly to skate around the corner. The radius controlled by the traction exercise is often smaller than the actual turning radius, and it is impossible to simulate the tilt angle of the corner well. Continuous circling training will cause athletes to feel dizzy and unable to practice cornering techniques for a long time, which will affect the performance of athletes' technical level and the long-term practice of technical movements.

[0004] The static traction ice training method is to fix one side of the traction rope and connect the other side to the trainee. The trainee keeps the curve posture in place and performs certain ice-pushing exercises, while the upper part of the body remains relatively static. This training method can well train the trainee's ankle strength and ability to resist centrifugal force, but this method cannot simulate the effect of the real centrifugal force in the dynamic process, and there is no practice in real dynamic activities. There is a lack of real cornering experience, and it is impossible to practice the selection of the matching of the cornering angle and the appropriate momentum, which affects the athlete's real physical feeling and correct feedback when cornering.

[0005] The land simulation training method is to connect the practitioner with the assistant through traction by elastic bands. The practitioner maintains the cornering posture and moves laterally on the rough ground to train the corresponding muscle groups and overcome the influence of centrifugal force on cornering. However, this ground simulation training method also does not have the real feeling of the ice surface, and only has the force moving in the left and right directions. It does not simulate the state of forward movement and is still limited to relatively static antagonistic training. There is a certain limit to the improvement of athletes' technical level.

[0006] In summary, the current cornering training methods cannot solve the problems of practicing on the ice, resisting dizziness, and cornering at speed and being adjustable at the same time. Innovative research on short track speed skating cornering technical practice methods and corresponding improvement plans are urgently needed. Summary of the invention

DETAILED DESCRIPTION

[0031] like Figure 1-Figure 3 As shown, this embodiment provides a short track speed skating curve dynamic training simulation system, including a base 1, a rotating ice platform 2, a driving device, a VR visual device (VR glasses), a data acquisition device, a data analysis device and a control center, wherein the rotating ice platform 2 is rotatably arranged on the base 1, and a simulated track 3 for athlete training is provided on the rotating ice platform 2; the driving device is used to drive the rotating ice platform 2 to rotate relative to the base 1, the VR visual device is used to provide a training scene for the athlete, and the data acquisition device is used to collect the athlete's training data; the data analysis device analyzes the athlete's training data and provides feedback, and the driving device, VR visual device, data acquisition device and data analysis device are all connected to the control center.

[0032] The rotating ice table 2 includes an ice surface layer, a refrigeration layer and a base layer which are arranged in sequence, the refrigeration layer is provided with a refrigeration pipeline 4, the base layer is connected with a support seat 5, and the support seat 5 is rotatably matched with the base 1.

A refrigerator 6 connected to the refrigeration pipeline 4 is provided at the bottom of the base layer, the refrigerator 6 is connected to the control center, and a conductive slip ring 7 electrically connected to the refrigerator 6 is provided on the support seat 5.

[0033] In this embodiment, the driving device includes a variable frequency drive motor 8, a reducer 9 and a transmission mechanism, the output end of the variable frequency drive motor 8 is connected to the reducer 9, and the reducer 9 is connected to the support base 5 through the transmission mechanism. The transmission mechanism includes an outer gear ring 10 and a gear 11 that mesh with each other, the outer gear ring 10 is arranged on the support base 5, and the gear 11 is arranged at the output end of the reducer 9.

[0034] In order to improve the safety of athletes, the short track speed skating curve dynamic training simulation system also includes a safety protection device, which is used to provide safety protection for athletes. The safety protection device includes a ring beam 12 and a traction rope 13. The ring beam 12 is arranged above the rotating ice platform 2. The top end of the traction rope 13 is connected to the ring beam 12, and the bottom end of the traction rope 13 is fixed to the athlete. Preferably, the traction rope 13 is provided with an emergency tightening device 14.

[0035] The control center is connected to an ice surface monitor 15, an alarm, a spray device 16 and an ice repairing device 17. The ice surface monitor 15, the spray device 16 and the ice repairing device 17 are all arranged above the rotating ice table 2.

[0036] In the training of traditional speed skating, athletes usually rely on fixed ice tracks for practice. These tracks are composed of straight and curved tracks, in which the straight part is easy for athletes to control their body balance because the sliding path is straight and stable. However, when skating on the curve, due to the strong centrifugal force generated by high-speed movement, if the athlete cannot accurately control the body posture and balance, it is very easy to fall. In order to avoid such situations, athletes often need to actively slow down before the curve to ensure safe passage. Although this strategy improves safety, it significantly sacrifices the sliding speed, which in turn has an adverse effect on the competition results. In view of the above challenges, it is particularly important to develop a device and method designed specifically for speed skaters to train on curves. The core of the present invention is to simulate the real competition environment. The turning radius of the rotating ice platform 2 accurately matches the curve radius of the actual competition track, ensuring the high simulation of the training environment. The motor part uses a variable frequency motor and integrates a programmable logic controller (PLC) for intelligent control. This configuration enables the training device to flexibly adjust the rotation speed according to specific training needs, providing athletes with a variety of training conditions. By precisely controlling the speed of the motor, the device can simulate curve gliding scenarios of different difficulty levels, helping athletes to effectively improve their body control and gliding skills on curves without having to slow down.

[0037] The system helps athletes train by:

[0038] Simulates real ice environment: The system uses a rotating simulated ice surface that accurately mimics the shape and size of an actual curve. This design allows athletes to practice on non-real ice, but still experience the physical reaction and ice feel similar to the actual track.

[0039] Dynamic Centrifugal Force Simulation: By rotating the platform, the system is able to generate centrifugal forces similar to those in actual turns, challenging athletes' ability to maintain balance during high-speed turns. This helps athletes learn how to effectively control their bodies to maintain speed and stability.

[0040] Safety assurance: The integrated emergency protection technology can react quickly when the athlete falls or loses control, protecting the athlete from injury by automatically slowing down and tightening the traction rope13, increasing the safety of training.

[0041] Personalized training settings: The intelligent control system allows athletes or coaches to adjust training parameters such as speed and rotation intensity as needed, making training more in line with personal needs and technical development stages.

[0042] Application of virtual reality technology: The integration of VR technology provides an immersive training environment, allowing athletes to practice in a simulated competition environment, interact with virtual opponents, and improve their competitive level and ability to cope with actual competitions.

[0043] Data feedback and analysis: The system can monitor and record training data in real time, such as speed, heart rate, body posture, etc., and provide detailed feedback to athletes and coaches to help them analyze and improve training results.

[0044] In the present invention, the variable frequency drive motor 8 is the power source of the entire system, which can provide continuous and stable power to ensure that the entire system can move smoothly and ensure the authenticity of the simulation. Six variable frequency drive motors 8 can be used to cooperate with each other to ensure the stability and synchronization of power output. The variable frequency drive motor 8 is precisely adjusted by the control center (PLC control technology) to meet the corresponding speed of different training requirements and meet the training conditions of athletes.

[0045] The reducer 9 is the deceleration source of the system. The reducer 9 controls the speed and torque of power transmission to ensure that the system can decelerate slowly and stably and efficiently when it needs to decelerate. The reducer 9 adopts a multi-stage gear 11 transmission to achieve stable deceleration and braking, so as to gradually reduce the speed of the high-speed motor and output the corresponding low-speed and high-torque operating power to the system, ensuring that the system can smoothly transition during braking and avoiding damage to the motor and wear of the gear 11 and other equipment caused by excessive braking.

[0046] The transmission mechanism transmits the rotational power of the motor to the rotating ice table 2 by meshing the outer gear ring 10 and the gear 11, so that the rotating ice table 2 can maintain a suitable rotation speed, and can respond quickly and dynamically to the rotation speed changes in high-speed motion. The transmission is driven by the outer gear ring 10 and the gear 11 to drive the angular contact bearing to rotate so that the system can operate stably, ensuring efficient transmission and reducing energy loss. The outer gear ring 10 is made of an alloy material with high wear resistance, strong fatigue resistance and appropriate strength, so that the system can operate for a long time, reducing the occurrence of damage and replacement of parts. An angular contact bearing is arranged between the support seat 5 and the base 1 to ensure the stable operation of the system under different load conditions. The transmission method of the outer gear ring 10 and the gear 11 greatly improves the transmission efficiency, reduces power loss, and plays a key role in the overall efficiency of the system.

[0047] In addition, the present invention also designs a safety protection device, which can provide safety protection for athletes.

[0048] The traction rope 13 is the main safety protection measure in this design. The traction rope 13 connects the trainer to the ring beam 12 and plays a safety protection function. It is made of high-strength, wear-resistant synthetic fiber material, has good tensile strength and ductility, can withstand the momentum change caused by the athlete during emergency braking, provide corresponding deceleration buffer, avoid damage caused by direct impact, and greatly improve the safety factor of the trainer.

[0049] The emergency tightening device 14 can protect the trainee in time in an emergency by responding quickly to prevent him from being thrown off the training platform. The emergency tightening device 14 is used in the safety protection system in short track speed skating training, and specifically prevents athletes from falling and getting injured through an intelligent control. The core of the equipment design is an emergency tightening device with a sensing function, which can automatically activate the protection mechanism when falling. The working principle of the emergency tightening device is as follows:

[0050] In normal state: the traction rope 13 is in a relaxed state, allowing the trainee to slide freely without affecting the sliding process. The emergency tightening device does not impose any constraints to avoid limiting the freedom of movement.

[0051] When falling: Once the trainee falls or tilts to a certain angle, the sensor inside the emergency tightening device will sense the force change and start. At this time, the emergency tightening device will tighten quickly, pull up the trainee, prevent him from falling on the ice, and reduce injuries.

[0052] Technical features: This emergency tightening device is different from ordinary spring devices. It is equipped with an induction sensor. When the body tilts abnormally (for example, when falling), the device can respond quickly and automatically tighten through the induction system to provide safety protection.

[0053] Adjustment of the traction rope: The length of the traction rope of the equipment can be adjusted according to each person's height and weight. The rope length and force monitoring system of each trainer can be customized according to individual differences to ensure that users of different body types can get proper protection. The adjustment of the rope length is to ensure that it will not restrict free movement during the sliding process, but also provide timely protection in case of falls.

[0054] Sensor function: There is a force sensor in the device that can monitor the skater's posture and force status in real time. When a fall or abnormal force (such as excessive tilt) is detected, the system will trigger an alarm and start adjusting the tension of the rope.

[0055] Adjustment method: Before each training session, the equipment settings need to be adjusted based on the height, weight, and other information of the participants. The specific situation of each trainee (such as weight differences) will affect the response of the equipment, so when training with multiple people, the equipment parameters of each person need to be adjusted separately.

[0056] The rotating ice platform 2 is a stable and controllable ice surface platform, which restores the curved part of the standard training ground in a one-to-one ratio, symmetrically forming a circular ice platform, which can support multiple people to train at the same time. The rotating ice platform 2 is equipped with intelligent digital control technology, and the rotation speed of the rotating ice platform 2 can be manually adjusted through the human-computer interactive interface to achieve the training goal. The rotating ice platform 2 adopts a layered design, consisting of a base layer, a refrigeration layer and an ice surface layer, wherein the base layer is responsible for maintaining stability and structural support, and the refrigeration pipeline 4 in the refrigeration layer actively regulates the ice surface state of the ice surface layer, and the ice surface layer provides a good training environment for athletes. The refrigerator 6 rotates synchronously with the rotating ice platform 2, which solves the connection problem between the refrigeration channel and the ice surface. The power supply is connected to the conductive slip ring 7 through a cable to ensure the safety and reliability of the system.

[0057] The device supports multiple people training at the same time (four people). When the levels of multiple trainers are similar, they can train together. The speed adjustment of the device will remain consistent to ensure that everyone is skating in a relatively similar training state. The design of the device is similar to a treadmill, which can maintain a relatively static state with the ice surface. Even if multiple people are training, it will not affect the overall function of the device.

[0058] This system can provide an immersive training experience. Trainees can enter the rotating ice platform 2 by wearing VR visual devices (VR glasses), which can better simulate the competition environment and provide real-time feedback on current body indicators, current motion data, and related guidance, etc. The system is equipped with a variety of training scenarios and modes, which are diverse and interesting, and provide trainees with diversified training methods to adapt to different competition scenarios. The VR visual device can generate virtual opponents in a virtual environment, and can also generate pacers with corresponding PB scores or target scores, simulating the competition scenes of real competitions, and providing players with safe and competitive training programs. Coaches and trainers can adjust training parameters, increase training uncertainty, record training data and body postures, etc. through the human-computer interaction interface, which provides reference and basis for the formulation of future training plans.

[0059] When the short track speed skating curve dynamic training simulation system of the present invention is used, the trainee wears the corresponding sportswear and the VR glasses of the present design, enters the ice surface through the initial entrance on the side of the platform, wears the traction rope 13 independently or through an assistant, selects and adjusts the training parameters and selects a suitable training scene through the human-computer interaction interface of the VR glasses, and the off-site assistant or coach can also adjust the training environment of the trainee. After everything is ready, the rotating ice platform 2 rotates slowly to give the trainee time to adapt, gradually accelerates to the target pace, and the trainee adjusts the cornering posture by tilting the body angle, and crosses the left and right legs irregularly to push the ice to maintain body stability and forwardness, ensuring that the trainee does not exceed the reasonable range of ice platform training. After the training cycle is completed or the training is terminated in advance, the rotating ice platform 2 slows down to ensure that the trainee can slow down to ensure his safety. If the trainee encounters an accident during the training process, the emergency tightening device 14 will be triggered, and the rotating ice platform 2 will slow down at the same time, which greatly improves the trainee's safety index. After the training is completed, the training data provided by the intelligent system can be viewed, and the next training plan can be formulated according to one's own conditions.

[0060] Since continuous training is an important way to ensure that athletes can master continuous force, the system is continuously driven by a high-speed motor and the speed is adjusted by a human-computer interactive panel, ensuring the intensity of athletes' training and meeting the different speed requirements of different individuals. On the platform, athletes can glide at a certain speed, maintain a suitable glide angle on the curve, better master the sense of force of the action, and can master different curve techniques and body tilt angles by adjusting the speed, thus improving individual practical skills.

[0061] During the process of skating on a curve, the athlete will be affected by the centrifugal force and will tend to move away from the center point. The faster the speed, the easier it is for the athlete to move to the outside of the curve. In order to counteract the effect of this centrifugal force, the athlete needs to maintain body balance and stability by stretching and adjusting the body movement angle to the outside of the curve, and skate on the curve at the fastest speed possible while ensuring a safe cornering angle. The present invention rotates the rotating ice table 2 to increase the speed at which the athlete can perform training, while also maximally simulating the centrifugal force that the athlete is subjected to when cornering, providing a good method for practicing cornering balance and selecting a suitable cornering angle.

[0062] In traditional traction training exercises, the practitioner will inevitably move around the center of the circle, which is easy to cause dizziness. It is not an active exercise to feel dizzy, which reduces the quality of training. In the present invention, the athlete skates on the rotating ice platform 2, and the rotating ice platform 2 rotates. The athlete moves relative to the ice surface without displacement in actual distance, which realizes the training of maintaining balance on the curve and ensures that the athlete will not reduce the quality of training due to passive dizziness.

[0063] The system solves the problem that land-based simulation training cannot simulate the real ice surface, giving trainees a real feeling of the ice surface, providing centrifugal force through rotation, providing conditions for trainees to actively exert force to maintain balance, and at the same time alleviating the discomfort caused by the ropes tied around the waist and abdomen of the trainees. In addition, the VR technology simulates the competition environment in real time, giving trainees a more realistic experience, interacting with virtual opponents, adding fun and competitiveness. Trainees can practice overtaking techniques in this environment, and by adjusting the skating posture and speed, they can find the best time and route to overtake, which helps to enhance athletes' competitive awareness and ability to cope with competitions.

[0064] The system reduces the risk of accidental injury during training. Avoiding accidental injury during training is the top priority in preparing for competitions. Reducing the occurrence of injuries is also a point of concern in the field of sports equipment. The emergency tightening device 14 is an effective countermeasure. When a trainee accidentally falls or stalls, the emergency tightening device 14 will take emergency protective measures for the trainee, the traction rope 13 will tighten the athlete to avoid secondary injuries, and the rotating ice platform 2 will also achieve the purpose of slowing down by reducing the rotation speed. Other trainees will also slow down slowly during this process to protect the safety of the trainees.

[0065] This embodiment also provides a short track speed skating curve dynamic training simulation method, which is applied to the short track speed skating curve dynamic training simulation system mentioned above, and the short track speed skating curve dynamic training simulation method comprises the following steps:

[0066] Training preparation: Before entering the training, athletes need to wear appropriate speed skating equipment, including speed skating suits, protective gear, speed skating shoes, and VR glasses. These equipment are designed to protect the safety of athletes and simulate real competition conditions. Athletes enter the rotating ice platform 2 through the side entrance.

[0067] Parameter setting: Before the training begins, the coach or athlete sets the training parameters through the human-computer interaction interface, including the rotation speed of the rotating ice table 2, the selection of training scenes, and the difficulty of the virtual opponent. The selected training scene can simulate the real competition environment, allowing athletes to train under conditions close to the competition.

[0068] Start training: The rotating ice table 2 will rotate slowly before starting training, allowing the athletes to gradually adapt to the rotating environment. Then, according to the previously set parameters, the rotating ice table 2 starts to rotate at the set speed. At this time, the athletes need to use ice skates to skate on the ice surface to simulate the curve action in the game; during the training process, if the ice surface monitor 15 detects that the ice surface is uneven, the alarm will sound and the rotating ice table 2 will gradually stop rotating;

[0069] Dynamic feedback and adjustment: Coaches can monitor the performance of athletes in real time, provide real-time feedback through the human-computer interaction system, and guide athletes to adjust their skating posture and technique. The system analyzes the athlete's dynamic data, such as skating speed, body tilt angle, etc., and provides feedback to help athletes optimize their techniques.

[0070] End of training and review analysis: After the training, the rotating ice platform 2 will slowly stop to ensure the safety of the athletes. Athletes can replay the training process through video and analyze technical movements with coaches to find out what needs to be improved.

[0071] Filling the ice surface: After the training, the ice surface monitor 15 is used to monitor the uneven state of the ice surface. If a groove is detected on the ice surface, the spray device 16 sprays liquid into the groove of the ice surface, and the ice repair device 17 scrapes the liquid in the groove flat, and the excess liquid is scraped off from the edge of the rotating ice table 2. The ice repair device 17 then freezes the liquid in the groove so that the groove is filled after the liquid solidifies.

[0072] Safety protection: During the entire training process, the traction rope 13 and the emergency tightening device 14 ensure that the athlete can quickly stabilize and prevent falling when losing balance or encountering an accident. The entire training system is equipped with multiple safety monitoring to ensure a quick response in any technical failure or emergency. Through this training method, athletes can effectively improve their technical ability and body coordination in dealing with high-speed curves in a safe environment, and enhance their competitive performance in the competition.

[0073] The short track speed skating dynamic curve training simulation system designed by the present invention has certain benefits for the curve technique practice of short track speed skaters, especially for improving the competition results of professional athletes and strengthening curve techniques. It also provides a new method for short track speed skating training and provides new ideas for the development of short track speed skating.
