[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0034] See also Figure 1 , Figure 1 Schematic diagram of the structure of a sports equipment provided by an embodiment of the present invention. Figure 1 As shown, the sports equipment includes an equipment body 200, an active component 100, a plurality of sensors 101, an RFID electronic tag device 102, an RFID reading and writing device 202 and a controller 201, wherein the active component 100, the RFID reading and writing device 202 and the controller 201 are all installed on the equipment body 200, the plurality of sensors 101 and the RFID electronic tag device 102 are installed on the active component 100, the RFID electronic tag device 102 is wirelessly connected to the RFID reading and writing device 202, and the RFID reading and writing device 202 is connected to the controller 201.

[0035] The sports equipment includes but is not limited to sports, fitness and rehabilitation training equipment, as long as it includes a movable part 100 and an equipment body 200. The movable part 100 and the equipment body 200 vary according to the specific form of the sports equipment. For example, if the sports equipment is a snowboard, the equipment body 200 is the snowboard body, and the movable part 100 is a fixing mounted on the snowboard body. For another example, if the sports equipment is a robot, the equipment body 200 is the robot body, and the movable part 100 is a movable mechanical arm mounted on the robot body.

[0036] The sensor 101 includes but is not limited to a pressure sensor, a temperature sensor 101 and a gyro sensor 101, etc., and a specific sensor type can be set as needed. The number of sensors 101 can also be set as needed, generally multiple sensors, for collecting data from multiple locations or multiple angles.

[0037] The sensor 101 is installed on the movable part 100 and is used to collect data of the movable part 100 to obtain collected data. For example, if the sensor 101 is a pressure sensor, the collected data is the pressure data of the movable part 100, if the sensor 101 is a temperature sensor, the collected data is the temperature data of the movable part 100, and if the sensor 101 is a gyro sensor, the collected data is the angle data of the movable part 100.

[0038] If wired communication is used to complete the data transmission between the movable component 100 and the controller 201, it is inevitable that the signal transmission will be unreliable due to gaps, dirt, wear and tear, or a large number of designs need to be applied to avoid it, such as complex algorithms, expensive materials, etc., and these measures will increase the hardness or maintenance costs, and the lifespan will also be shortened to varying degrees.

[0039] Therefore, in this embodiment, wireless transmission is used to complete the data transmission between the active component 100 and the controller 201. Specifically, the controller 201 transmits the data acquisition instruction and the data transmission instruction to the RFID reader / writer 202, so that the RFID reader / writer 202 wirelessly transmits the data acquisition instruction and the data transmission instruction to the RFID electronic tag device 102. After receiving the above instructions, the RFID electronic tag device 102 obtains the collected data from the several sensors 101 and wirelessly transmits the collected data to the RFID reader / writer 202. The RFID reader / writer 202 then transmits the collected data to the controller 201, which receives, processes and analyzes the data, thereby realizing the data transmission between the data of the active component 100 and the controller 201.

[0040] Therefore, the data of the active parts in the sports equipment can be wirelessly transmitted to the controller through RFID technology, and processed and analyzed by the controller. Compared with wired transmission, the data transmission method of the sports equipment is more reliable, simpler in design and lower in cost.

[0041] In some embodiments, after receiving the data collection instruction and the data transmission instruction, the RFID reader / writer is also used to feed power to the RFID electronic tag device so that the RFID electronic tag is in working state.

[0042] Therefore, the sports equipment does not need a battery to support the above-mentioned wireless transmission, thereby avoiding the problem of increased volume and cost caused by a charging interface or a wireless charging module.

[0043] The controller 201 may also be a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a single chip microcomputer, an ARM (Acorn RICS Machine) or other programmable logic device, a discrete gate or transistor logic, a discrete hardware component or any combination of these components. In addition, the controller 201 may also be any conventional processor, controller, microcontroller or state machine. The controller 201 may also be implemented as a combination of computing devices, for example, a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in combination with a DSP and / or any other such configuration.

[0044] See also Figure 2 , Figure 2 Schematic diagram of the structure of a sports equipment provided by the embodiment of the utility model. Figure 2 As shown, the RFID electronic tag device 102 includes a logic control module 1021 and an RFID tag antenna 1022 . The logic control module 1021 is connected to the plurality of sensors 101 and the RFID tag antenna 1022 , respectively. The RFID tag antenna 1022 is also wirelessly connected to the RFID reader / writer 202 .

[0045] Among them, when the RFID reading and writing device 202 transmits data collection instructions and data receiving instructions to the RFID electronic tag device 102, the RFID tag antenna 1022 receives the above instructions and transmits them to the logic control module 1021. The logic control module 1021 then obtains the collected data from several sensors 101 according to the data collection instructions and transmits the collected data to the RFID reading and writing device 202 via the RFID tag antenna 1022 according to the data transmission instructions.

[0046] In some embodiments, please refer to Figure 2 and Figure 3The logic control module 1021 includes a signal processing chip 10211 and an RFID channel chip 10212. The analog-to-digital conversion terminals (ADC pins) of the signal processing chip 10211 are connected to the sensors 101, the data terminal (SDA pin) of the signal processing chip 10211 is connected to the data terminal (SDA pin) of the RFID channel chip 10212, the control terminal (SCL pin) of the signal processing chip 10211 is connected to the control terminal (SCL pin) of the RFID channel chip 10212, and the input signal terminal (IN pin) of the signal management chip is connected to the RFID tag antenna 1022. Figure 3 In the figure, six sensors 101 are taken as an example, and the six sensors 101 are respectively connected to six analog-to-digital conversion terminals of the signal processing chip 10211.

[0047] The signal processing chip 10211 obtains the collected data from the sensor 101 according to the data collection instruction, and stores the collected data in the RFID channel chip 10212. The RFID channel chip 10212 then transmits the collected data to the RFID reader / writer 202 via the RFID tag antenna 1022 according to the data transmission instruction.

[0048] The logic control module 1021 may also include a first resistor R1 and a second resistor R2, wherein the first resistor R1 is connected in series between the power supply and the data end of the signal processing chip 10211 or the data end of the RFID channel chip 10212, and the second resistor R2 is connected in series between the power supply and the control end of the signal processing chip 10211 or the control end of the RFID channel chip 10212.

[0049] The model of the signal processing chip 10211 is STM32U073K8, and the model of the RFID channel chip 10212 is FM11 NT082C. The data end of the RFID channel chip 10212 and the control end of the RFID channel chip 10212 are its contact interfaces, and the input end of the RFID channel chip 10212 is its non-contact interface.

[0050] In some embodiments, Figure 2 As shown, the RFID reader / writer 202 includes an RFID reader / writer 2021 and an RFID reader / writer antenna 2022 . The RFID reader / writer 2021 is connected to the controller 201 and the RFID reader / writer antenna 2022 , respectively. The RFID reader / writer antenna 2022 is also wirelessly connected to the RFID tag antenna 1022 .

[0051] The RFID reader / writer 2021 transmits the data collection instruction and the data transmission instruction to the signal processing chip 10211 via the RFID reader / writer antenna 2022, the RFID tag antenna 1022 and the RFID channel chip 10212, so that the signal processing chip 10211 obtains the collected data from the several sensors 101, and stores the collected data in the RFID channel chip 10212, and transmits it to the RFID reader / writer 2021 via the RFID tag antenna 1022 and the RFID reader / writer antenna 2022.

[0052] Taking a snowboard as an example, the wireless transmission method of the sports equipment is described. In this case, the sensor 101 is a pressure sensor, the movable component 100 is a fastener, and the equipment body 200 is a snowboard body.

[0053] like Figure 4 As shown, the fixing is installed on the snowboard body by screws, one fixing is provided for each left and right foot, and a set of screw holes is provided at each left and right foot of the snowboard body, so that the fixing is connected to the snowboard body by screws. The controller 201 is installed in the middle position of the snowboard body to facilitate the connection with other components. In this embodiment, the controller 201 is a PCBA with the chip model nRF52840 as the core.

[0054] like Figure 5 As shown, the fixture has six built-in pressure sensors and a signal processing chip 10211, wherein the number of pressure sensors can be set as needed, such as 8 or 4.

[0055] Each pressure sensor is connected to the signal processing chip 10211, specifically, connected to the analog-to-digital conversion terminal of the signal processing chip 10211. During skiing, each pressure sensor collects the pressure value of each part of the binding, and the pressure value is transmitted to each analog-to-digital conversion terminal of the signal processing chip 10211 through the line.

[0056] The data end of the signal processing chip 10211 is connected to the data end of the RFID channel chip 10212 , and its control end is connected to the control end of the RFID channel chip 10212 . The input end of the RFID channel chip 10212 is also connected to the RFID tag antenna 1022 .

[0057] like Figure 6 As shown, a group of RFID reader antennas 2022 are arranged around the screw holes of the fixers located at the left and right feet. The number of RFID reader antennas 2022 is the same as the number of fixers, and they are installed one-to-one with the fixers. The RFID reader antennas 2022 are connected to the RFID reader 2021 built into the controller 201.

[0058] like Figure 7 As shown, the area of ​​the RFID reader antenna 2022 is larger than the area of ​​the RFID tag antenna 1022. When the fixing installation position needs to be adjusted, the RFID tag antenna 1022 is within the effective communication coverage of the RFID reader antenna 2022, and wireless transmission is achieved between the RFID reader antenna 2022 and the RFID tag antenna 1022.

[0059] The working principle of this ski can be described as follows:

[0060] When the skis are turned on, the pressure values ​​of various parts of the bindings need to be transmitted to the controller 201. During skiing, each pressure sensor collects the pressure values ​​of various parts of the bindings in real time to obtain collected data;

[0061] The controller 201 sends a data collection instruction. After the RFID reader 2021 receives the data collection instruction, the RFID reader 2021 feeds power to the RFID tag antenna 1022 via the RFID reader antenna 2022, so that the signal processing chip 10211 and the RFID channel chip 10212 obtain energy and start working at the same time, and the signal processing chip 10211 obtains the collected data from the sensor 101 and stores the collected data in the RFID channel chip 10212;

[0062] The controller 201 sends the data transmission instruction again, the RFID reader 2021 feeds the RFID tag antenna 1022 again via the RFID reader antenna 2022, and the RFID channel chip 10212 is in working state, which executes the data transmission instruction and transmits the stored collected data to the RFID reader 2021 via the RFID tag antenna 1022 and the RFID reader antenna 2022. The RFID reader 2021 then transmits the collected data to the controller 201, so that the controller 201 processes and analyzes the collected data.

[0063] Therefore, the data of the active parts in the sports equipment can be wirelessly transmitted to the controller through RFID technology, and processed and analyzed by the controller. Compared with wired transmission, the data transmission method of the sports equipment is more reliable, simpler in design and lower in cost.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Under the idea of ​​the present invention, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes in different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents.
