Description

Technical Field

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

[0002] Traditional training often relies on manual timing or simple electronic devices, which suffers from problems such as inaccurate reaction time capture, poor timing synchronization, and low data recording efficiency. Existing start detection systems typically use wired connections, which are complex to install and difficult to adapt to the rapid deployment requirements of outdoor tracks. Furthermore, they are prone to damage or signal interruption due to pulling or tugging.

[0003] Some wireless timing systems use Bluetooth or Wi-Fi communication, but their transmission distance is limited and their anti-interference capabilities are weak. In open areas or multi-device environments, packet loss and delays are prone to occur, affecting timing accuracy. Furthermore, most systems lack compatible interfaces with traditional mechanical blind watches, failing to meet the dual-core requirements of specific scenarios. Starting signals often rely on starting pistols or handheld whistles, lacking standardized command procedures, and the intervals between preparation and starting signals are inconsistent, affecting the fairness and scientific rigor of reaction time measurements.

[0004] Regarding finish line timing, manual timing has significant subjective errors, high-speed photography systems are expensive, and ordinary photoelectric gates lack sufficient response accuracy and are mostly fixed installations with poor flexibility. Results display and recording are mostly done manually or by printing from external devices, making the process cumbersome and unable to achieve integrated detection, transmission, display, and output.

[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 provides a competition training system, comprising: An athletics starting detection terminal includes an LCD screen 3 and a pressure sensing module 4. The LCD screen 3 and the pressure sensing module 4 are connected via a wireless LoRa communication module. The LCD screen 3 is equipped with a blind gauge interface and a pressure adjustment button 13. The command assembly includes a wireless command handle and a blind meter 2. The wireless command handle is connected to the LCD screen 3 via a wireless LoRa communication module, and the blind meter 2 is wired to the LCD screen 3 via a blind meter interface. An infrared beam-through assembly includes a pair of infrared transmitters 6 and infrared receivers 7. The infrared beam-through assembly has a built-in wireless LoRa communication module. The infrared transmitters 6 and infrared receivers 7 are symmetrically arranged. The LED performance display screen 5 is connected to the track and field start detection terminal and the infrared beam assembly via a wireless LoRa communication module.

[0019] This technical solution achieves precise monitoring and data traceability of the entire process of track and field starting training—from starting signal to preparation, start, and finish—through a starting component triggering the timing start, a pressure sensing module 4 collecting the starting status, an LCD screen 3 integrating the starting data, an infrared beam component capturing the finish line, and an LED results display screen 5 presenting and outputting the results. The specific principle is as follows: Both the LCD screen 3 and the LED score display screen 5 have built-in temperature-compensated high-precision crystal oscillators. The two periodically exchange time calibration signals through the wireless LORA communication module to solve the timing error caused by time drift in traditional wireless systems. The command component offers both wireless and wired options. The wireless command handle is linked to the LCD screen 3 via a wireless LORA communication module, which is suitable for team training. The blind meter 2 is wired and connected via the blind meter interface of the LCD screen 3, which is suitable for individual training without wireless signal. Both are triggered by a three-stage logic of "on your positions", "ready", and "gunshot", and the command time is synchronously written to the LCD screen 3 and the LED display. The pressure sensing module 4 monitors the pressure value of the athlete during preparation in real time and transmits the pressure data to the LCD screen 3 via the wireless LoRa communication module. When the athlete's starting foot triggers a pressure exceeding the preset threshold, the LCD screen 3 immediately calculates the reaction time at the starting moment and displays the pressure curve, reaction time, and starting moment in separate sections. The transmitter and receiver of the infrared beam beam assembly symmetrically cover the finish line of the track. When the athlete crosses the finish line and blocks the infrared light, the assembly transmits the crossing time to the LED score display screen 5 through the built-in LORA module. Data integration and output: The LED performance display screen 5 receives the reaction time, command time and crossing time of the infrared component from the LCD screen 3. After being analyzed by the LED control card, it is displayed on the monochrome screen and supports the output of documents by thermal printer, forming a complete closed loop of training, testing and recording.

[0020] The wireless starting handle has four buttons: Ready, Ready, Gunshot, and Stop. The speaker 12 is integrated on the top of the handle. It has a built-in rechargeable lithium battery, a Type-C charging port on the side, and is equipped with both network and standby switches. After switching the network switch, the wireless command handle automatically pairs with the LCD screen 3 via the wireless LORA communication module; press the "Ready in Position" button 8, the speaker 12 plays the "Ready in Position" voice message, and simultaneously sends the command phase 1 signal to the LCD screen 3, which records the initial command time; after an interval of 2-3 seconds, press the "Ready" button 9, play the "Ready" voice message, and send the command phase 2 signal; after another interval of 1-2 seconds, press the "Gunshot" button 11, play the simulated gunshot, send the command phase 3 signal, and the LCD screen 3 starts timing; Press the stop button 10, and the wireless command handle sends a reset command to the LCD screen 3. The LCD screen 3 simultaneously triggers the LED performance display 5 to reset the time to zero, displaying 00:00:00.000. The next round of training can be started without powering off, which is suitable for multi-person training. Switching the single-unit switch can disconnect the wireless LORA universal selection module connection, allowing commands to be issued only via wired connection through blind meter 2, adapting to complex electromagnetic environments, such as multi-device interference scenarios.

[0021] LCD screen 3 primarily uses a 2.4-inch monochrome LED screen, with a LORA antenna on the top and a blind meter interface on the side, such as a dedicated Type-C adapter and pressure adjustment button 13. It also features a built-in rechargeable lithium battery and a temperature-compensated high-precision crystal oscillator. Press the pressure adjustment button 13, and the LCD screen 3 cycles through pressure thresholds such as 50N, 80N, 100N, ..., 200N, and a pop-up window displays the current threshold to adapt to athletes of different weights; the pressure sensing module 4 transmits real-time pressure data to the LCD screen 3 through the wireless LoRa communication module, and the pressure curve is dynamically drawn on the left side of the screen. A fluctuation of ≤10N is judged as a stable preparatory posture. LCD screen 3 receives the time calibration signal from LED score display screen 5 via wireless LoRa communication module, and corrects the local time using its own temperature-compensated crystal oscillator; at the same time, it forwards the reaction time and command time to LED score display screen 5 via wireless LoRa communication module to achieve data synchronization.

[0022] The LED score display screen 5 primarily uses a 320×160 monochrome LCD screen, with a LORA antenna on the top, a thermal printer on the back, a built-in rechargeable lithium battery, an LED control card, and a temperature-compensated high-precision crystal oscillator, and printing and clearing operation buttons 14 on the side. LED score display screen 5 serves as the time reference for the entire system. Every 10 seconds, it sends a time calibration command to LCD screen 3 via wireless LoRa communication module. LCD screen 3 adjusts its local time using a clock algorithm, thus solving the problem of time synchronization issues among multiple devices in traditional wireless systems. The LED control card receives the reaction time, starting time and finish time from the infrared component on the LCD screen 3, integrates them according to athlete number, reaction time and finish time format, and displays them on the LED results display screen in 5 minutes and 3 lines with the font size adapted for the coach to observe from a distance. Press the print button to print the results sheet on the thermal printer, which includes training time, reaction time, finish time, and a thumbnail of the pressure curve for easy archiving and analysis; press the clear button to manually clear the screen data to avoid confusion between multiple sets of data.

[0023] The infrared transmitter 6 and infrared receiver 7 of the infrared beam assembly are symmetrically fixed on both sides of the runway finish line, and have built-in wireless LORA communication module and lithium battery. Infrared transmitter 6 continuously emits invisible infrared light, which is received in real time by infrared receiver 7. When an athlete crosses the finish line, if the athlete's foot or leg blocks the light, the infrared receiver 7 will receive a sudden drop in light intensity of ≤0.05μW / cm², immediately triggering the finish line signal. The finish line time is then transmitted to the LED results display screen 5 via the wireless LORA communication module.

[0024] In this technical solution, the LCD screen 3 and the LED score display screen 5 are equipped with a conventional application main control chip STM32L051C8T6, a temperature-compensated crystal oscillator module DS3231, a driver chip SSD1963, and a power management chip TP4056 to achieve the relevant functions of the above applications.

[0025] The pressure sensing module 4 in this technical solution can be a conventional flexible pressure sensor or a resistive pressure sensor such as the RRP-S40-ST model.

[0026] Detailed Workflow Phase 1: Equipment Deployment and Initialization Step 1: Hardware Placement and Fixing Place the LCD screen 3 in the coach observation area at the starting line of the track, and fix the pressure sensing module 4 in the athlete's starting step area to ensure that the signal of the wireless LORA communication module of the two is unobstructed. Secure the transmitter and receiver to opposite sides of the finish line on the runway and turn on the power. The LED performance display screen 5 is placed in the coach rest area next to the track. When the power is turned on, the screen enters the time synchronization standby mode. Switch the wireless command handle to network mode and press the power button. The wireless command handle will automatically pair with the LCD screen 3. If using the blind meter 2, connect it to the blind meter interface of the LCD screen 3 via a dedicated cable. The LCD screen 3 will then display that the blind meter 2 is connected.

[0027] Step 2: Parameter settings and time synchronization Press the pressure adjustment button 13 on the LCD screen 3 to set the threshold to the target value, such as 100N, to suit athletes of moderate weight. Confirm in the pop-up window and exit. The LED score display screen 5 automatically sends a time synchronization signal to the LCD screen 3 and the infrared component. The LCD screen 3 displays that the time synchronization is complete, and the indicator light on the infrared component flashes once. If synchronization fails, the position of the LED score display screen 5 is adjusted to ensure that the LORA antenna is unobstructed, and synchronization is retried.

[0028] Phase Two: Starting and Starting Inspection Step 1: Three-stage command trigger The coach holds a wireless command handle, faces the athletes and gives instructions, while simultaneously pressing the "Ready Positions" button 8 and the speaker 12 plays the "Ready Positions" voice message. The LCD screen 3 records the time of the command, such as 5:20:00.000, and displays the time of the command on the right side. The athlete enters the ready position, and the pressure curve is dynamically drawn on the left side of LCD screen 3; after a 3-second interval, the ready button 9 is pressed and the ready voice message is played, while LCD screen 3 continues to draw the pressure curve. Press the gunshot button 11 after a 2-second interval to play a simulated gunshot. The LCD screen 3 will immediately start the timer, and the middle area will display "Timer in progress".

[0029] Step 2: Starting Parameter Collection and Forwarding When the athlete starts running, the pressure sensor module 4 suddenly increases the pressure value to over 100N. The module then sends a start trigger signal to the LCD screen 3 via the wireless LoRa communication module. LCD screen 3 stops timing, calculates reaction time (e.g., 0.142s), and updates the reaction time display in the middle area; simultaneously, it forwards the reaction time and command time to LED score display screen 5 via wireless LoRa communication module. LCD screen 3 maintains the display of pressure curve, reaction time, and command time until it is reset in the next training session.

[0030] Phase 3: Finish Line Testing and Results Presentation Step 1: Transmission of the crossing signal As the athlete sprints along the track, their legs block the beam of the infrared beam-transmitting component when they cross the finish line. The infrared receiver 7 triggers the finish line signal, and the finish line time is transmitted to the LED results display screen 5 via the wireless LORA communication module.

[0031] Step 2: Grade Integration and Display The LED control card analyzes the data and displays the reaction time and finish time of number 1 on the first line of the LED results display screen 5. It retains the first two sets of historical data. The second and third lines allow coaches to intuitively compare the results of multiple people.

[0032] Step 3: Output Results Press the print button on LED score display screen 5, and the thermal printer will output the score sheet, which includes the training date, time, reaction time, finish time, and pressure curve thumbnail. The sheet can be archived as a training record.

[0033] Phase 4: Training Reset and Data Processing Step 1: Single-round training reset Pressing the stop button 10 on the wireless command handle triggers a reset command on the LCD screen 3, clearing the pressure curve, reaction time, and command time data. Simultaneously, the LED performance display screen 5 is reset and displayed. If the athlete's weight is different, repeat step 2.1 to adjust the pressure threshold, such as 80N for light-weight athletes and 150N for heavy-weight athletes.

[0034] Step 2: Finishing with multiple rounds of training After multiple training sessions are completed, press the print button on the LED score display screen 5 to output all score reports in batches, or export the data via the wireless LoRa communication module; Check the battery level of each device. If the battery is low, charge it through the power interface and charging interface. Turn off the power to all devices and complete the training.
