Description

Technical Field

[0001] The present invention belongs to the field of sports equipment, relates to campus sports detection equipment, and in particular to an early warning precise timing system for long-distance running scenes in smart sports. Background Art

[0002] The middle- and long-distance running test is a relatively inefficient test item. Currently, most middle- and long-distance running equipment uses induction carpet + ultra-low frequency induction + RFID to collect data. The number of traditional test tags will not exceed fifty, and the test process cannot be customized into groups, multiple groups, or multiple groups. There are errors in the result counting, the equipment on-site network layout is complex, and the results are easily lost. Data export requires networking and is inconvenient to operate. During large-scale middle- and long-distance running with more than a hundred people at the same time, it is impossible to display heart rate and abnormal heart rate warning in real time throughout the 400-meter playground, which greatly reduces sports risks and avoids sports casualties. Summary of the invention

[0003] In view of the above problems, the present invention provides an early warning precise timing system for long-distance running scenarios in smart sports.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] An early warning and accurate timing system for long-distance running scenarios in smart sports, comprising a data smart box, wherein the data smart box has a wearable heart rate device and a Bluetooth working module;

[0006] The wearable heart rate device is provided with a six-axis acceleration sensor and a heart rate sensor.

[0007] Preferably, a smart Bluetooth base station is also included.

[0008] Preferably, the wearable heart rate device supports BLE 5.1 ​​protocol, operating frequency: 2.402GHz~2.483GHz frequency: 2.4GHz / 13.56MHz / 125KHz, supports ultra-low frequency wake-up, and operating frequency is 125kHz±1kHz.

[0009] Preferably, the smart Bluetooth base station has a built-in high-gain 18dBi single-polarized antenna and two external 5dbi omnidirectional antennas.

[0010] Compared with the prior art, the advantages and positive effects of the present invention are:

[0011] 1. The Bluetooth smart gateway adopts distributed deployment, which drives more terminal devices and enhances the high-gain coverage range of 150 meters +; it adopts Bluetooth 5.0 data interaction mode, low power consumption, long signal transmission distance, simple on-site deployment, and data can be synchronized to various smart devices such as tablets at any time.

[0012] 2. Test efficiency is greatly improved. The test process can be customized into groups, multiple groups, or mixed tests of multiple groups. No need to divide males and females into groups, saving group queuing time; multiple groups can run at the same time, making full use of the track space. The intelligent physical data box numbering and student pre-numbering method are adopted, so that students can be directly identified on site without the need to call out names one by one.

[0013] 3. High fault tolerance rate. The calculation of middle and long-distance running results is completely based on the calculation of the terminal device and stored in the wearable terminal device. Even if the tablet, smart Bluetooth base station and other devices occasionally fail, once the data is restored, it will be re-uploaded to the tablet via broadcasting, and the data will not be lost. High fault tolerance rate.

[0014] 4. The grade data is accurate. The entire grade collection process is based on each student's device working offline. There is no need to use other devices through the network for calculation. The worn device is always in the same position as the student's body.

[0015] 5. Real-time detection of sports safety can greatly reduce sports risks and avoid sports casualties. Real-time detection without blind spots. Through two smart Bluetooth base stations with 90-degree teaching signal coverage, the entire playground is covered to detect the heart rate and sports data of each student in real time. During the test, the heart rate and abnormal heart rate warning can be displayed in real time. In case of abnormality, the bracelet vibrates to remind the individual, the tablet reminds the physical education teacher, and the Bluetooth speaker reminds the on-site personnel to intervene in physical education teaching.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] Embodiment 1, as Figure 1 As shown, the present invention provides an early warning and accurate timing system for smart sports middle and long-distance running scenes, using a data intelligent box to store wearable heart rate devices (supporting BLE 5.1 ​​protocol, operating frequency: 2.402GHz~2.483GHz frequency: 2.4GHz / 13.56MHz / 125KHz, supporting ultra-low frequency wake-up, operating frequency 125kHz±1kHz, six-axis acceleration sensor / heart rate sensor), a single box capacity of 60, a quota for one class. Bluetooth working module, with signal broadcast mode and master-slave working mode.

[0021] At the starting point of the 400-meter playground, a high-performance smart Bluetooth base station (built-in high-gain 18dBi single-polarized antenna, external 2 5db i omnidirectional antennas) is set up, 1.5 meters above the ground, and can be hung on street lights or monitoring equipment. The device has three built-in Bluetooth concurrent devices, and a single device covers more than 50 terminal devices, covering signals at a 30-degree angle, and the effective distance of device signal reception is 150 meters +. Ordinary 12V batteries can be used for power supply, and ordinary poles can also be used to assume mobile scenarios. Built-in load balancing algorithm, based on the strength of the received Bluetooth signal (RSS I) and load pressure, distributed data distribution processing is performed between the three built-in Bluetooth devices.

[0022] At the end of the runway, a ULF induction coil carpet is placed. The length is 7.5 meters and can cover 6 runways. Each induction coil has an independent number and can trigger a 125k antenna signal. 400-meter playground, 800-meter run, the start and end points coincide, 2 laps; 1000-meter run, the end point is 200 meters away from the start point. 3 laps.

[0023] At the starting point, a teaching tablet is placed with built-in Bluetooth 5.0, which can communicate with the smart Bluetooth base station. The tablet is connected to a Bluetooth speaker at the starting point to broadcast the sound of the running starting gun.

[0024] 5. Function implementation logic,

[0025] 1) Students wear smart wristband devices in batches to detect heart rate once a second. The data is broadcast via Bluetooth and transmitted to a high-performance smart Bluetooth base station. The tablet connects to the Bluetooth base station to obtain the heart rate data of each device in real time. In the preparatory stage, the devices worn by students are switched to connection mode and wait for running instructions in real time.

[0026] 2) After the tablet plays the running gunshot command through the Bluetooth speaker, the tablet sends the running command to the Bluetooth device worn by the student through the connected Bluetooth base station.

[0027] The distance between the three Bluetooth devices is within 10 meters, and the instruction is sent within 0.1 seconds. After receiving the instruction, which includes the number of laps, the wristband device works offline and starts to count the running seconds for each individual student.

[0028] Multi-class, mixed-gender test, mixed-gender test identity recognition mode:

[0029] 1. Data initialization: number the data boxes by school, No. 1: ZTX-001, No. 2: ZTX-002, No. X: ZTX-XXX

[0030] 2. Synchronize the system initialization data on the tablet, select the data intelligent box number ZTX-XXX (60 devices, based on MAC number for identity recognition), and select the starting class students (numbered 1-60)

[0031] 3. Perform the starting action of the second class multiple times, so that students from multiple classes can run at the same time on the playground

[0032] 4. In the mixed test mode for men and women, men and women place the sensing carpet according to step 3.

[0033] 5. When the student wears the device and runs to the ultra-low frequency induction coil carpet position, the built-in 125k antenna is used to complete the clock-in record, and the terminal device records the current running time difference. The terminal device records the time once each circle passes the sensing position, and the wristband vibrates to remind the student that the clock-in is successful. The effective clock-in interval near the sensing position is 10 seconds. The terminal wearable device displays the score results, such as

[0034] First lap: 0 minutes 30 seconds

[0035] Second lap: 1 minute 30 seconds ...

[0037] Data format: See the attachment.

[0038] Data transmission frequency: Bluetooth data is broadcast once per second and aggregated to the tablet via the smart Bluetooth gateway for performance display.

[0039] 4. When the student runs laps according to the command data sent and the terminal device calculates the number of laps to reach the set number, the timing is stopped and the results are locked and saved in the terminal device.

[0040] Continue to broadcast data scores. Because the scores are locked, individual scores will no longer change and data loss will be avoided. As long as the data is synchronized with the smart Bluetooth gateway successfully, the tablet can get the final score.

[0041] 5. When students are running, their heart rate data per second is collected through the smart Bluetooth gateway and aggregated to the tablet device for real-time heart rate warning. It is managed in four color segments: 0-120: water color, resting state

[0042] 120-150: Blue, light aerobic exercise

[0043] 150-180: Light red, aerobic exercise state

[0044] 180 or above: Red, there is a safety hazard, the bracelet vibrates for 5 seconds, the tablet is marked with a red sign, and the Bluetooth speaker prompts. The teacher can intervene

[0045] 6. Running performance counting logic description:

[0046] Trigger ID: Wearable device MAC

[0047] Induction ID: ground sensor coil ID.
