Description

Technical Field

[0001] This utility model relates to the field of sports training equipment technology, specifically a swimming competition training system. Background Technology

[0002] Traditional swimming timing systems mostly rely on wired connections, resulting in complex wiring between devices and cumbersome installation. This is especially problematic when deployed over long distances in standard swimming pools, where cable laying is costly, prone to damage, and difficult to adapt to the flexible configuration requirements of multi-lane pools. Some systems use short-range wireless technologies such as Bluetooth or Wi-Fi, but their anti-interference capabilities are weak, and their transmission distance is limited. In the complex electromagnetic environment of a pool, signal interruptions or delays can easily occur, affecting timing accuracy.

[0003] Existing training systems typically lack a unified remote control mechanism. Operations such as issuing commands, starting timings, and resetting equipment require manual coordination or on-site operation, resulting in non-standardized processes and difficulty in achieving synchronous control across multiple terminals. Although some systems have introduced wireless starter pistols or handheld terminals, their functions are limited and cannot achieve equipment status monitoring and remote management. Furthermore, touchpad signal acquisition terminals are mostly fixed designs with weak data processing capabilities, lack external expansion interfaces, and are difficult to integrate sensors for physiological parameters such as heart rate and blood oxygenation, thus limiting the comprehensiveness of training data.

[0004] Regarding score display, traditional systems often use a single display screen, which cannot meet the multi-angle viewing needs of coaches, referees, and athletes. Some LED screens do not use high-precision timing components, resulting in clock drift over long periods of operation, affecting the timing reference. In addition, score recording mostly relies on manual input or external printing, which is cumbersome and lacks instant printing functionality, hindering rapid archiving and analysis.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 The present invention relates to a swimming competition training system, comprising: The control module includes a remote controller 1, a wireless blind meter 2, and a wireless command transmitter. The remote controller 1 is equipped with at least three function buttons. The terminal controller 4 includes a near-end swimming terminal, a far-end swimming terminal, and a multi-lane wireless terminal, wherein the lane wireless terminal has a built-in data processing unit. The display module includes a main screen 6, at least two secondary screens 7 and an LED display screen 8, wherein the LED display screen 8 is equipped with a DISPCARDS™32F407 display card; The sensing module includes a touch panel 5 corresponding to the terminal controller 4 and an external sensor interface, wherein the external sensor interface is configured on the terminal controller 4. The control module is connected to the terminal controller 4 and the display module via the LORA module, and the terminal controller 4 is connected to the display module via the LORA module.

[0019] This technical solution achieves full-scenario coverage for dual-terminal single-lane training, multi-lane group training, and multi-lane competition by triggering commands through a control module, collecting and processing data through a terminal controller 4, capturing motion signals through a sensor module, and presenting output results through a display module. The specific core logic is as follows: Time reference construction: The temperature-compensated high-precision crystal oscillator of the main screen 6 in the display module is used as the time reference for the whole system. Every 10 seconds, a time synchronization signal is sent to all terminal controllers 4 through the LORA module to solve the timing error caused by time drift in the traditional system. The control module outputs commands according to the scenario. During dual-terminal training, remote controller 1 sends ready, start, and stop commands to the near-end swimming terminal and the far-end swimming terminal through the LORA module. During single-lane group training, wireless blind meter 2 sends commands one-to-one with the corresponding terminal controller 4 through the RF4 module. During multi-lane competition, the wireless starting device broadcasts commands globally to all terminal controllers 4 through the RF4 module to adapt to different training needs. In the sensing module, the touch plate 5 transmits the wall contact signal to the terminal controller 4 through a waterproof shielded cable. The external sensor interface can be selected to connect to extended data such as pressure and attitude sensors. The core chip built into the terminal controller 4 uses STM32L476RG / STM32F407IGH6 and CTM8251KAT serial port chip to work together to convert the raw signal into standardized data such as start reaction time, lane distance, and motion parameters. Terminal controller 4 transmits data through RF2 / RF4 and LORA modules. In dual-terminal scenarios, it is directly connected to LED display screen 8. In multi-lane scenarios, it sends data to the main screen 6 / sub-screen 7 at 0.1s intervals to avoid signal conflicts. After receiving the data, the display module parses it through the DISPCARDS™32F407 display card and displays the data on the main screen 6 / sub-screen 7. The data is then output and archived through a thermal printer. The LED display screen 8 shows a red light indicating stop, a yellow light indicating preparation, and a green light indicating start, providing real-time feedback on the system's operation. Coaches and athletes can intuitively judge the operation points, reducing the risk of misjudgment.

[0020] The remote control 1 has a built-in LoRa module and three buttons: device key 9, stop key 10, and reset key 11. It supports one-to-one communication with the terminal controller 4 and the LED display 8. Short press device button 9 to switch between ready and start functions. In ready mode, remote control 1 sends a command to terminal controller 4, terminal controller 4 plays a ready voice message through the speaker, and the status light on LED display 8 turns yellow. In start mode, the command is transmitted synchronously to terminal controller 4 and LED display 8, the terminal starts timing, and the status light on LED display 8 turns green. When the stop button 10 is pressed, the terminal controller 4 immediately freezes the timing data, and the LED display 8 stops updating the display, adapting to scenarios such as athletes adjusting their movements and temporarily checking equipment. Pressing the reset button 11 clears the historical data of the terminal controller 4, and the status light on the LED display 8 resets to red, ensuring that the next round of training starts from zero and avoiding data confusion.

[0021] The wireless blind meter 2 has a built-in RF4 module, two buttons for issuing commands and stopping, and each blind meter is pre-bound to a multi-lane wireless terminal; When the start button is pressed, the blind watch only sends an RF4 signal to the bound terminal. After the terminal receives the signal, it starts timing. Other lane terminals are not affected, making it suitable for one-on-one coaching scenarios. Pressing the stop button 10 will only stop the timing of the bound terminal, avoiding the interruption of multiple training sessions caused by the traditional one-stop-all approach, and improving the utilization rate of the venue.

[0022] The wireless command transmitter has a built-in RF and features two buttons for global command and global stop. It supports broadcasting signals to up to 10 terminals. Pressing the global start button, several terminal controllers 4 simultaneously start timing, and all lane status lights on the LED display 8 turn green, meeting the requirements for a fair start in the competition; When the match ends or an emergency occurs, press the global stop button 10. All terminals will freeze data and transmit it to the main screen 6 at 0.1-second intervals. The main screen 6 will quickly integrate the rankings and improve referee efficiency.

[0023] The near-end / far-end swimming terminal prioritizes the use of the STM32L476RG chip: responsible for low-power data processing in dual-terminal scenarios. After receiving the LORA signal from the remote controller 1, it calculates the start reaction time through the built-in timer, the time difference between issuing the command and triggering the touchpad 5, and drives the speaker to play voice. The data is directly connected to the LED display 8 through the LORA module, meeting the battery life and immediacy requirements of single-lane training.

[0024] The multi-lane terminal prioritizes the use of the STM32F407IGH6 chip: it is responsible for complex data processing in multi-lane scenarios. After receiving the signal from the wireless blind meter 2 / starter RF4, it synchronously processes the touchpad 5 signal and external sensor data, such as stroke frequency. It transmits data in time-division according to the lane number to avoid signal conflicts between multiple terminals and adapt to large-scale training.

[0025] CTM8251KAT chip: Serial communication conversion chip, connecting terminal controller 4 and peripherals; The analog trigger signal of the touchpad 5 and the digital signal of the external sensor, such as the heart rate data of the SPO02 sensor, are converted into UART standard signals and transmitted to the core chip for processing, thus solving the problem of incompatibility between different sensor signal formats.

[0026] The ST-Link interface typically includes SWCLK / RST / GND / SWDIO pins: By connecting the ST-Link debugger to the PCB board of the terminal controller 4, the SWIM_TERMINAL_1.hex / SWIM_TERMINAL_2.hex program is programmed to the near-end / far-end swimming terminal, and the time-division transmission program is programmed to the multi-lane terminal. At the same time, it supports real-time debugging of data processing logic, reducing development and maintenance costs.

[0027] SPO02 sensor interface: Adapted to the SPO02 blood oxygen sensor, it collects blood oxygen saturation data of athletes during training through the I2C communication protocol, transmits it to the terminal controller 4, and links it with reaction time and distance data to display blood oxygen and speed curves on the main screen 6 to assist coaches in assessing physical exertion.

[0028] The RF2 / RF4 module interface connects to the LORA module, enabling point-to-point communication with the remote controller 1, LED display 8, main screen 6, and wireless blind meter 2 / commander.

[0029] The main screen 6 has a built-in DS3231 temperature-compensated crystal oscillator with a temperature compensation range of -40℃ to 85℃. It sends a time synchronization command to all terminal controllers 4 every 10 seconds. After receiving the time-sharing data from the multi-lane terminals, it integrates the data into a ranking, reaction time, and distance format according to the lane number, and prioritizes displaying the data of lanes 1-4 to provide core reference for coaches.

[0030] The two secondary screens 7 have the same parameters as the main screen 6. The first secondary screen 7 receives the data for lanes 5-7 distributed by the main screen 6, and the second secondary screen 7 receives the data for lanes 8-10, avoiding information overload on a single screen. The secondary screens 7 are updated synchronously with the main screen 6, adapting to large-scale training scenarios with 10 lanes.

[0031] The LED display screen 8 preferentially adopts model P10(3535)16×32-2S-v1.3, is equipped with DISPCARDSTM32F407 display card, has red, yellow and green LEDs, and a thermal printer is connected to the back. After receiving data from the terminal controller 4, the display card parses it into distance and time format, such as 50m00:45.32, and displays it on the LED display screen 8. The thermal printer simultaneously outputs the score report, which includes timestamp, lane number, and reaction time, for easy archiving and analysis.

[0032] The touch plate 5 is fixed to the pool walls at both ends of the swimming lane and adopts an IP67 waterproof design. When the athlete touches the wall, the pressure sensor of the touch plate 5 generates an analog signal, which is transmitted to the terminal controller 4 through a waterproof shielded cable to avoid triggering delay caused by wireless signal attenuation in the water.

[0033] Terminal controller 4 is equipped with external sensor interfaces for HO / HI / TRA / SUG pins, supporting the connection of multiple types of sensors: Connect a pressure sensor: collect the force of pushing off the wall at the start, and the terminal calculates the force and reaction time data to help optimize the force exertion action; Connect to the MPU6050 attitude sensor: collect stroke angle and turn angular velocity, and generate motion curves on the main screen for technical correction; Connect to a heart rate sensor: Monitor heart rate changes in real time. When the heart rate exceeds a threshold, such as 180 beats / minute, the terminal triggers a speaker alarm to ensure training safety.

[0034] The terminal controller 4 has a built-in speaker that is connected to the core chip of the terminal controller 4 through a conventional circuit. When receiving a pre-command from the remote controller 1 or a command from the wireless blind meter 2, the speaker plays a pre-command voice. When the heart rate exceeds the threshold, a heart rate warning sound is played, providing both visual and auditory prompts.

[0035] Detailed Workflow Scenario 1: Dual-terminal single-lane training Step 1: Equipment Deployment and Initialization Hardware placement: The near-end swimming terminal is placed at the starting point of the lane, and the far-end swimming terminal is placed at the ending point of the lane.

The main screen 6 displays lanes 1-2, the first sub-screen 7 displays lanes 3-3, and the second sub-screen 7 displays lanes 4-5.

[0039] Step 2: Training Process Single lane start: The coach holds wireless blind watch No. 3, presses the start button, and only terminal No. 3 starts timing. The reaction time is displayed on the secondary screen of lane 73: 00:00.000. Other lanes can be trained independently, such as blind watch No. 1 controlling lane No. 1. Data transmission: When the swimmer in lane 3 touches the wall, the terminal sends data to the main screen 6 in a 0.3s sequence. The secondary screen 7 updates lane 3: reaction time 0.128s, distance 50m; Single lane stop: Press the stop button 10 on the blind watch 3, the timing on terminal 3 will stop, and the data on sub-screen 7 will freeze; the coach can clear the data on terminal 3 by pressing the reset button 11 on the blind watch and start the next set of training.

[0040] Step 3: Training Conclusion After all group training is completed, the main screen 6 integrates the data from 5 lanes and outputs the data in batches; pressing the clear button on the main screen 6 will reset all terminals and displays.
