[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0036] Long jump performance is a crucial indicator for measuring an athlete's coordination and explosive power. It not only directly reflects an athlete's horizontal displacement ability but also, to some extent, their physical qualities, including muscle strength, speed control, and flexibility. Long jump performance is essential for evaluating training effectiveness and developing personalized training plans.

[0037] However, in current practice, the methods for measuring long jump performance remain relatively traditional, mainly relying on manual measurement using tools such as measuring tapes and tape measures. This method is not only time-consuming and inefficient, especially in large-scale competitions or training sessions where it requires waiting for measurement personnel to measure and record each result, significantly extending the overall time of the competition or training; moreover, due to the subjectivity and visual errors of manual operation, the measurement results often have considerable uncertainty.

[0038] Exploring more efficient and accurate methods for measuring long jump performance has become a pressing technical problem for those skilled in the art. Based on this, this application proposes a long jump system. This technical solution achieves automatic measurement of long jump performance by setting up a processor, a first signal transmitter, and at least three signal receivers.

[0039] One embodiment of this application provides a long jump system, such as... Figure 1 As shown, the long jump system includes a processor 10, a first signal transmitter 11, and at least three signal receivers. It should be noted that... Figure 1 The embodiment shown has three signal receivers 12. This does not limit the long jump system to only three signal receivers. The number of signal receivers can be set according to the actual situation. This embodiment does not limit it.

[0040] The first signal transmitter 11 is positioned at the heel of the long jumper and moves with the jumper during the jump. The first signal transmitter 11 can transmit a first long jump signal. In some embodiments, the first signal transmitter 11 transmits the first long jump signal at fixed time intervals. These time intervals can be set according to actual conditions, for example, 10 ms; this embodiment does not limit this. In other embodiments, the first long jump signal is a modulated data frame containing data content and a timestamp, where the timestamp is the transmission time of the first long jump signal. When the data content and timestamp of any two first long jump signals are identical, it indicates that these two first long jump signals are the same.

[0041] The aforementioned at least three signal receivers are fixedly positioned at different locations. That is, if a three-dimensional coordinate system is established based on the long jump system, the coordinates of the aforementioned at least three signal receivers are fixed and unchanging, and the coordinates of any two signal receivers are different. However, during the long jump, the first signal transmitter 11 moves with the jumping object, and the coordinates of the first signal transmitter 11 will change.

[0042] All three signal receivers described above are used to receive the first long jump signal. In some embodiments, the first signal transmitter 11 is an RF transmitter, and the signal receiver 12 is an RF receiver. The RF transmitter and RF receiver include devices such as modems, power amplifiers, filters, RF switches, frequency dividers, and antennas, which are not limited in this embodiment.

[0043] Each signal receiver is communicatively connected to the processor 10. A mature processor device from the prior art can be used as the processor 10 in this embodiment, such as an octa-core processor or a quad-core processor; this embodiment is not limited to any particular type. In one specific embodiment, an MT6737V quad-core processor is used as the processor 10.

[0044] The communication connection can be a wireless communication connection based on a wireless network or a wired communication connection based on a data transmission line; this embodiment does not limit the type of connection. The aforementioned wireless network can be any type of network. For example, a wireless network can be a single network, further subdivided into multiple sub-networks. Specifically, the wireless network or the multiple sub-networks included in the wireless network can be at least one of cellular mobile networks (e.g., 2G, 3G, 4G, or 5G), ZigBee, Wi-Fi, and Bluetooth, or any combination of at least one of these networks with other networks.

[0045] After receiving the first long jump signal, the signal receiver 12 sends the first long jump signal to the processor 10. The processor 10 determines the long jump distance based on the coordinates of each signal receiver 12 and the time when each signal receiver 12 receives the first long jump signal.

[0046] In one specific embodiment, when the long jumper is preparing to jump at the take-off position, he / she can manually operate the first signal transmitter 11 to start transmitting the first long jump signal; after the long jumper lands, he / she can operate the first signal transmitter 11 again to stop transmitting the first long jump signal.

[0047] It should be noted that after receiving the first long jump signal, the signal receiver 12 first demodulates it, extracts the data content and timestamp, and records the reception time of each first long jump signal. Then, it sends the demodulated data content, timestamp, and reception time of the first long jump signal to the processor 10. The processor 10 compares the first long jump signals received by each signal receiver 12. If the data content and timestamp of the first long jump signals received by each signal receiver 12 are the same, then the first long jump signals received by each signal receiver 12 are considered to be the same signal. In this way, the time when each signal receiver 12 receives the same first long jump signal, as well as the transmission time of the first long jump signal, can be obtained.

[0048] Thus, for any first long jump signal, based on the time when each signal receiver 12 receives the first long jump signal, the coordinates of each signal receiver 12, and the transmission speed of the first long jump signal, the position coordinates (x, y, z) of the first signal transmitter 11 when transmitting the first long jump signal are determined, using the following formula:

[0049]

[0050]

[0051] In the above formula, (x1,y1,z1)(x2,y2,z2)(x3,y3,z3) represent the coordinates of three signal receivers, t1 represents the time when the signal receiver at coordinates (x1,y1,z1) receives the first long jump signal, t2 represents the time when the signal receiver at coordinates (x2,y2,z2) receives the first long jump signal, t3 represents the time when the signal receiver at coordinates (x3,y3,z3) receives the first long jump signal, and c represents the transmission speed of the first long jump signal.

[0052] It should be noted that if the first signal transmitter 11 includes a radio frequency transmitter and the signal receiver 12 includes a radio frequency receiver, then the first long jump signal is a radio frequency signal and the transmission speed of the first long jump signal is the speed of light.

[0053] In this way, the coordinates of the first signal transmitter 11 when all the first jump signals are transmitted can be calculated.

[0054] The take-off and landing positions of the long jump participant are the two positions closest to the ground for the first signal transmitter 11 during the long jump process. In some embodiments, the two coordinates closest to the ground are selected from the coordinates of the first signal transmitter 11 when all first long jump signals are emitted as the take-off point coordinates and the landing point coordinates. For example, if the z-axis of the coordinate system is a coordinate axis perpendicular to the ground, then the two coordinates with the smallest z-values ​​can be selected as the take-off point coordinates and the landing point coordinates.

[0055] In other embodiments, the first signal emitted after the first signal transmitter 11 is activated is taken as the signal emitted at the take-off point. For ease of explanation, this embodiment defines this signal as the take-off signal. The last signal emitted before the first signal transmitter 11 is deactivated is taken as the signal emitted at the landing point. For ease of explanation, this embodiment defines this signal as the landing signal. The coordinates of the first signal transmitter when emitting the take-off signal can be calculated as the coordinates of the take-off point according to the above formulas (1)-(4), and the coordinates of the first signal transmitter when emitting the landing signal can be calculated as the coordinates of the landing point.

[0056] The long jump distance can be calculated based on the coordinates of the take-off point and the landing point. For example, if the X-axis of the three-dimensional coordinate system is parallel to the specified long jump direction, the difference between the X-axis coordinates of the take-off point and the landing point can be used as the long jump distance.

[0057] The long jump system in the above embodiment includes a processor 10, a first signal transmitter 11, and at least three signal receivers 12. The first signal transmitter 11 is disposed at the heel of the long jumper and is used to transmit a first long jump signal. The at least three signal receivers 12 are fixedly disposed at different positions and are all used to receive the first long jump signal. All three signal receivers 12 are communicatively connected to the processor 10. The processor 10 automatically determines the long jump distance based on the coordinates of each signal receiver 12 and the time when each signal receiver 12 receives the first long jump signal. This eliminates the need for manual measurement, is time-efficient, and highly accurate.

[0058] Moreover, the method provided in this embodiment does not require taking pictures. Compared with the method of taking pictures of the landing point of the athlete's heel with a camera, then estimating the position of the landing point relative to the scale bar through image recognition algorithm, and then calculating the effective distance of the jump, this embodiment is not affected by weather conditions such as backlight, low light, rain, fog, haze, and sandstorms, and has a higher detection accuracy.

[0059] It should be noted that at least the coordinates of three signal receivers are required to calculate (x, y, z). Therefore, at least three signal receivers are required in the embodiments of this application. When four or more signal receivers are set, it is only necessary to expand (x, y, z) according to formulas (1)-(4) based on the coordinates of three of the signal receivers.

[0060] As an optional implementation method, the time difference between the launch time and the landing time of the first long jump signal can be calculated to obtain the flight time and the horizontal velocity component. Based on the position coordinates during the flight, a detailed motion trajectory of the athlete from takeoff to landing can be constructed, and motion parameters such as flight height, direction, vertical acceleration, horizontal acceleration, vertical velocity, horizontal velocity, initial horizontal velocity component, and initial vertical velocity component can be calculated. Based on the parameters measured above, relevant personnel can analyze the deficiencies in the takeoff action and provide training guidance suggestions to improve the athlete's takeoff action to a better state and improve long jump performance.

[0061] In the above embodiments, the long jumper needs to manually adjust the first signal transmitter 11 to control whether the first signal transmitter 11 emits the first long jump signal. This method may not only distract the long jumper and affect their movement state, but also requires manual operation, resulting in low intelligence. To solve the above problems, another embodiment of this application discloses, such as... Figure 2 As shown, the long jump system in the above embodiment also includes a first pressure sensor 13. The first pressure sensor 13 is disposed on the sole of the long jumper's foot, and both the first pressure sensor 13 and the first signal transmitter 11 are communicatively connected to the processor 10.

[0062] Since both the first signal transmitter 11 and the first pressure sensor 13 are located at the feet of the long jumper and need to move with the jumper, to avoid affecting the jumper's movement, the communication connections between the first pressure sensor 13 and the processor 10, and between the first signal transmitter 11 and the processor 10, are wireless communication connections based on a wireless network. This wireless network can be any type of network. For example, the wireless network can be a single network, which can be further subdivided into multiple sub-networks. Specifically, the wireless network or the multiple sub-networks contained within it can be at least one of cellular mobile networks (e.g., 2G, 3G, 4G, or 5G), ZigBee, Wi-Fi, and Bluetooth, or any combination of at least one of these networks with other networks.

[0063] Since the first pressure sensor 13 is located under the feet of the long jumper, the pressure data detected by the first pressure sensor 13 will decrease significantly after the long jumper takes off and enters the air; after the long jumper lands, the pressure data detected by the first pressure sensor 13 will increase again. Based on this, it is possible to determine whether the long jumper has taken off or landed based on the magnitude of the pressure data detected by the first pressure sensor 13.

[0064] Specifically, the first pressure sensor 13 detects pressure data in real time and sends the detected pressure data to the processor 10. If the processor 10 detects that the pressure data is less than the first data, it indicates that the pressure data has decreased and the long jumper takes off. At this time, the first signal transmitter 11 can be controlled to emit the first long jump signal. If the processor 10 detects that the pressure data is greater than the second data, it indicates that the pressure data has increased and the long jumper lands. At this time, the first signal transmitter 10 can be controlled to stop emitting the first long jump signal.

[0065] In the embodiments of this application, the take-off and landing times of the long jumper are determined by detecting the pressure changes under the feet of the long jumper, and then the working state of the first signal transmitter 11 is automatically controlled. In this way, the long jumper does not need to manually adjust the first signal transmitter 11, and it will not affect the long jumper's movement state and has a high degree of intelligence.

[0066] After a long jumper lands, there's a small chance they might land on their arms or hips if their posture in the air isn't standard. According to long jump rules, if an athlete lands on their arms or hips, and the distance between that landing point and the take-off point is less than the distance between the foot landing point and the take-off point, then that landing point (arms or hips) is used to determine the athlete's long jump score. However, in the above embodiment, this situation requires manual measurement, affecting the accuracy of the results.

[0067] To address the aforementioned problems, as an optional implementation, another embodiment of this application discloses, such as... Figure 3 As shown, the long jump system in the above embodiment also includes a second signal transmitter 14.

[0068] The second signal transmitter 14 is located at the target position of the long jumper. The target position of the long jumper refers to the position where the jumper is likely to land, other than the feet, during the long jump, including at least one of the elbows, palms, and hips.

[0069] The second signal transmitter 14 is used to transmit the second long jump signal; the signal receiver 12 is also used to receive the second long jump signal; and the processor 10 is used to determine the long jump distance based on the coordinates of each signal receiver 12 and the time when each signal receiver 12 receives the first long jump signal and the second long jump signal.

[0070] In a specific embodiment, the position coordinates of the second signal transmitter 14 when transmitting any second jump signal can be calculated according to formulas (1)-(4).

[0071] It should be noted that when calculating the position coordinates of the second signal transmitter 14 when transmitting any second jump signal, in formulas (1)-(4), t1 represents the time when the signal receiver with coordinates (x1, y1, z1) receives the second jump signal, t2 represents the time when the signal receiver with coordinates (x2, y2, z2) receives the second jump signal, t3 represents the time when the signal receiver with coordinates (x3, y3, z3) receives the second jump signal, and (x, y, z) represents the position coordinates of the second signal transmitter 14 when transmitting the second jump signal.

[0072] If the position coordinates of the second signal transmitter 14 when all second long jump signals are transmitted include the target coordinates whose distance from the ground is less than or equal to the distance between the landing point position coordinates and the ground, then the long jump distance is calculated based on the target coordinates and the starting point position coordinates.

[0073] In the embodiments of this application, the long jump score can be automatically calculated when the long jumper lands at the target position, without the need for manual measurement by staff. This not only saves time but also has a high accuracy rate.

[0074] As an optional implementation, another embodiment of this application discloses that the second signal transmitter in the above embodiment includes a radio frequency transmitter.

[0075] As an optional implementation, another embodiment of this application discloses, such as... Figure 4 As shown, the long jump system in the above embodiment also includes a long jump mat 15 on which the long jumper performs the long jump. To prevent the long jumper from slipping during the long jump, some embodiments provide an anti-slip structure on the long jump mat 15.

[0076] All three signal receivers are located inside the long jump mat. This integration of the signal receiver 12 with the long jump mat 15 prevents the signal receiver 12 from being lost. In some embodiments, the processor 10 is also located inside the long jump mat 15, thus concealing the relevant data transmission lines within the mat and ensuring safe operation.

[0077] As an optional implementation, another embodiment of this application discloses, such as... Figure 4As shown, the signal receiver 12 in the above embodiment includes a first signal receiver 121, a second signal receiver 122, and a third signal receiver 123. The first signal receiver 121 and the second signal receiver 122 are disposed at the first end of the long jump mat 15, and the third signal receiver 123 is disposed at the second end of the long jump mat 15; the first end is located on the side of the long jump mat 15 near the landing point, and the second end is located on the side of the long jump mat 15 near the take-off point.

[0078] By setting up only three signal receivers, costs can be saved while ensuring the coordinates of the first signal transmitter 11 are obtained. Moreover, this distribution of the three signal receivers can improve the accuracy of the coordinate calculation of the first signal transmitter 11.

[0079] In addition to the first pressure sensor 13 installed on the sole of the foot as described in the above embodiment, as an optional implementation, another embodiment of this application discloses, such as... Figure 5 As shown and Figure 6 As shown, the long jump mat 15 in the above embodiment is provided with a pressure sensor array 16 consisting of multiple second pressure sensors; the pressure sensor array 16 is communicatively connected to the processor 10. This communication connection can be a wireless communication connection based on a wireless network or a wired communication connection based on a data transmission line; this embodiment does not limit the connection.

[0080] The first signal transmitter 11 is also communicatively connected to the processor 10. Since the first signal transmitter 11 is located at the feet of the long jumper and needs to move with the long jumper, in order to avoid affecting the long jumper's movement, the communication connection between the first signal transmitter 11 and the processor 10 is a wireless communication connection based on a wireless network.

[0081] A pressure sensor array 16 is installed on the long jump mat 15. After the long jumper takes off, the pressure data detected by the pressure sensor array 16 will decrease significantly; after the long jumper lands, the pressure data detected by the pressure sensor array 16 will increase again. Based on this, it is possible to determine whether the long jumper has taken off or landed based on the magnitude of the pressure data detected by the pressure sensor array 16.

[0082] Specifically, the pressure sensor array 16 detects pressure data in real time and sends the detected pressure data to the processor 10. If the processor 10 detects that the pressure data is less than the first data, it indicates that the pressure data has decreased and the long jumper takes off. At this time, the processor 10 can control the first signal transmitter 11 to emit the first long jump signal. If the processor 10 detects that the pressure data is greater than the second data, it indicates that the pressure data has increased and the long jumper lands. At this time, the processor 10 can control the first signal transmitter 10 to stop emitting the first long jump signal.

[0083] In the embodiments of this application, the take-off and landing times of the long jumper are determined by detecting the pressure changes of the pressure sensor array 16 set on the long jump mat 15, thereby automatically controlling the working state of the first signal transmitter 11. In this way, the long jumper does not need to manually adjust the first signal transmitter 11, and it will not affect the long jumper's movement state and has a high degree of intelligence.

[0084] As an optional implementation, another embodiment of this application discloses that the long jump system of the above embodiment also includes a long jump shoe 17; a first signal transmitter 11 is disposed on the long jump shoe 17 and disposed at the heel of the rear foot.

[0085] In some embodiments, the first pressure sensor 13 is also disposed on the long jump shoe 17 and disposed on the sole of the shoe.

[0086] With this setup, the long jumper only needs to change into long jump shoes 17 before the jump, without needing to wear additional equipment such as the first signal transmitter 11, thus avoiding the impact of these additional devices on the long jump performance.

[0087] As an optional implementation, another embodiment of this application discloses a method including a fixing strap; the first signal transmitter is positioned at the heel of the long jumper via the fixing strap. In some embodiments, the first pressure sensor 13 is also fixed to the sole of the long jumper's foot via the fixing strap. This configuration, using only a fixing strap for fixation, eliminates the need for the long jumper to change shoes, making it convenient and more hygienic.
