Description

Technical fields:

[0001] This invention relates to the field of sports data acquisition and processing technology, specifically to an application of a sports data acquisition system based on electronic student ID cards. Background Technology

[0002] Electronic student ID cards, integrating radio frequency circuits, positioning circuits, and mobile communication circuits, can meet the needs of students for attendance, on-campus payments, and other functions. Currently, electronic student ID cards generally have a card-like body, carried by a lanyard or pin buckle. Because electronic student ID cards contain positioning circuits and can further incorporate pedometer circuits based on accelerometer sensors, they can fully meet the requirements for collecting student movement data. However, the current form of wearing electronic student ID cards is not conducive to the wearer's vigorous movements. Summary of the Invention

[0003] This invention addresses the shortcomings and deficiencies of existing technologies by proposing an application of a sports data acquisition system based on electronic student ID cards.

[0004] This invention achieves its purpose through the following measures:

[0005] An application of a sports data acquisition system based on an electronic student ID card is characterized in that the sports data acquisition system includes a host computer and at least one electronic student ID card that establishes data communication with the host computer. The electronic student ID card has a card-type main body and a detachable document body embedded in the card-type main body. The card-type main body has a groove-type housing cavity that mates with the document body. The outer shell of the document body is embedded in the housing cavity. The document body has a functional circuit. The card-type main body also has an accessory circuit receiving cavity for accommodating accessory circuits. The accessory circuits in the accessory circuit receiving cavity are electrically connected to the functional circuits in the document body via a magnetic connector. The male and female heads of the magnetic connector are respectively provided on the card-type main body and the document body, and the male or female head of the magnetic connector is connected to the accessory circuit or the functional circuit.

[0006] The functional circuit includes a main controller and a positioning circuit and an acceleration sensor respectively connected to the main controller;

[0007] The specific applications of the motion data acquisition system include the following:

[0008] The electronic student ID can enter the sports data collection mode manually or automatically. It collects the sports data and location data of the current electronic student ID wearer through the accelerometer and positioning circuit. The electronic student ID uploads the collected sports data, location data and sports time to the host computer, which stores and analyzes the data. In the sports data collection mode, the electronic student ID displays the current number of steps, duration and calories burned in real time.

[0009] The host computer sends exercise tasks to the electronic student ID, causing the electronic student ID to enter the exercise data acquisition mode. The exercise task includes the duration of the current task. After receiving the exercise task, the electronic student ID performs exercise data acquisition according to the duration of the current task.

[0010] The manual entry of the electronic student ID card into the motion data acquisition mode described in this invention means that the user activates the positioning circuit and acceleration sensor through the buttons on the electronic student ID card or the touch screen on the main body of the card to complete the acquisition of motion data.

[0011] The automatic entry of the electronic student ID card into the motion data acquisition mode described in this invention refers to the following: The accelerometer in the electronic student ID card detects the user's motion state. When the accelerometer continuously detects that the user is not stationary (for example, the accelerometer counts steps, and if the number of steps taken by the user exceeds a set threshold within a set time interval (e.g., within 1 minute, the set threshold can be 100 steps), it is considered that the user is currently in motion. The main controller outputs a prompt message "Are you in motion?" through the touch screen of the ID card body. The prompt message "Are you in motion?" can be broadcast through a speaker in the voice input and output circuit, or it can be prompted by a vibration motor that can output vibration signals to prompt the user to confirm the information in time. When the user confirms the information, the motion data acquisition mode is entered.

[0012] In non-classroom mode or standby mode, if the electronic student ID card of the present invention detects that the student has not made any movement judgment within a set time period, such as 2 hours, it will issue an exercise reminder (You've been studying hard! Get up and exercise!). Clicking the back button will turn it off. If the student starts exercising, they can click to enter the exercise interface.

[0013] In this invention, the male or female head of the magnetic connector connected to the accessory circuit is exposed inside the housing cavity, while the male or female head of the magnetic connector connected to the functional circuit is exposed on the outer shell of the document body.

[0014] The functional circuit of this invention includes a main controller, a positioning circuit, a power supply circuit, a touch display circuit, and a voice input and output circuit. The main controller is connected to the positioning circuit, the power supply circuit, the touch display circuit, and the voice input and output circuit. A touch screen is provided on the front of the document body, and the touch screen is connected to the touch display circuit. A power button is also provided on the document body shell, and the power button is connected in series in the power supply circuit. The voice input and output circuit is equipped with a microphone and a speaker. The main controller and the power supply circuit are connected to the male or female connector of a magnetic connector provided on the document body.

[0015] The accessory circuit of this invention includes a button circuit and a TYPE-C interface circuit. One end of the button circuit is connected to the female or male connector of the magnetic connector on the card-type body, and the other end of the button circuit is connected to the button on the card-type body. The TYPE-C interface circuit is connected to the female or male connector of the magnetic connector on the card-type body. Furthermore, the accessory circuit also includes a charging circuit, which includes a lithium battery with one end connected to the female or male connector of the magnetic connector on the card-type body. The lithium battery is also connected to the TYPE-C interface circuit.

[0016] The depth of the housing cavity of the card-type main body described in this invention is consistent with the thickness of the document body. Furthermore, to ensure fitting stability, a silicone pad layer is provided on the housing cavity to increase friction with the document body. The upper port edge of the housing cavity is chamfered, and the inner diameter at the upper port edge is slightly smaller than the maximum outer diameter of the document body. The outer edge of the document body has rounded chamfers to facilitate quick insertion when it is interference-fitted with the housing cavity. Furthermore, to ensure that the document body can be quickly removed from the card-type main body, a hollow portion is provided on the back of the housing cavity of the card-type main body to facilitate pushing the document body out of the housing cavity through the hollow portion.

[0017] The housing of the document body of the present invention is also provided with a connecting part for easy connection of watch strap, and a groove is opened on the housing cavity of the card-type body to facilitate the placement of the connecting part.

[0018] In this invention, the card-type main body is provided with a push button at the power button position corresponding to the main body of the certificate. When the main body of the certificate is fitted into the housing cavity, the push button is opposite to the power button of the main body of the certificate. When the push button is pressed, the power button can be pressed at the same time to complete the power on / off operation. The card-type main body is also provided with a lanyard hole for easy connection of a lanyard.

[0019] When in use, this invention can embed the main body of the ID card into the receiving cavity of the card-type main body to form a card-type electronic student ID card, or connect the main body of the ID card to the watch strap and fix it on the user's wrist, depending on the wearer's situation. When the main body of the ID card is embedded in the receiving cavity of the card-type main body, the functional circuit in the main body is electrically connected to the accessory circuit via a magnetic connector. At this time, the button circuit in the accessory circuit can send the pressing signal of the button on the card-type main body to the main body, and the lithium battery in the charging circuit of the accessory circuit can charge the main body. When the TYPE-C interface circuit in the accessory circuit is connected to an external charging device, it can charge both the lithium battery in the accessory circuit and the main body of the ID card. This invention can perform motion data acquisition and interact with an external host computer platform through the functional circuit located in the main body in various wearing modes.

[0020] Compared with traditional electronic student ID cards, this invention can significantly reduce the product size by housing the accessory circuitry and charging circuitry on the card-shaped main body. While ensuring the basic requirements of the main body's battery life, it makes the card easier to carry during running and jumping activities. It has significant advantages such as reasonable structure, easy assembly and disassembly, and flexible use. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0034] This example demonstrates an application of a sports data acquisition system based on electronic student ID cards, as shown in the attached document. Figure 1 As shown, the motion data acquisition system described in this example includes a host computer 23 and at least one electronic student ID card 24 that establishes data communication with the host computer. The electronic student ID card 24 has a card-type main body 1 and a detachable document body 2 that is embedded in the card-type main body 1. The card-type main body 1 has a groove-type housing cavity 3 that cooperates with the document body 2. The outer shell of the document body 2 is embedded in the housing cavity 3. The document body 2 has a functional circuit. The card-type main body 1 also has an accessory circuit receiving cavity 4 for accommodating accessory circuits. The accessory circuit in the accessory circuit receiving cavity 4 is electrically connected to the functional circuit in the document body 2 via a magnetic connector 5. The male and female heads of the magnetic connector 5 are respectively provided on the card-type main body 1 and the document body 2, and the male or female head of the magnetic connector 5 is respectively connected to the accessory circuit or the functional circuit.

[0035] The functional circuit includes a main controller 6 and a positioning circuit 7 and an acceleration sensor respectively connected to the main controller 6; as shown in the attached diagram. Figure 9As shown, the main controller 6 in this example uses the ARS3601 or ARS3603 main control chip with integrated wireless communication circuitry; the accelerometer uses a single-chip triaxial accelerometer of model QMA7981. The power supply pins VDD and VDDIO of QMA7981 are connected to the VDDIO pin of the main control chip, respectively. Its VDD voltage range is 1.71-3.6V. The SCX pin of QMA7981 is connected to the SCL pin of the main control chip for clock interaction, and the SDX pin of QMA7981 is connected to the SDA pin of the main control chip for data transmission.

[0036] As attached Figure 10 As shown, the positioning circuit 7 uses a GPS positioning circuit. In this example, a positioning chip of model TD1030 is selected. Its TX pin is connected to the UART3-TXD pin of the main control chip through a level conversion circuit, and its RX pin is connected to the UART3-RXD pin of the main control chip through another level conversion circuit. The level conversion circuit includes an NMOS transistor, two 100k resistors, and a 10k resistor. The first level conversion circuit is used to convert the 3.3V voltage to 1.8V voltage. The application of the motion data acquisition system specifically includes the following:

[0037] The electronic student ID 24 can manually or automatically enter the motion data acquisition mode. It collects the motion data and location data of the current electronic student ID wearer through the accelerometer and positioning circuit 7, respectively. The electronic student ID 24 uploads the collected motion data, location data and motion time to the host computer 23, which stores and analyzes the data. In the motion data acquisition mode, the electronic student ID 24 displays the current number of steps, duration and calories burned in real time.

[0038] The host computer 23 sends a sports task to the electronic student ID card 24, causing the electronic student ID card 24 to enter the sports data acquisition mode. The sports task includes the duration of the current task. After receiving the sports task, the electronic student ID card 24 performs sports data acquisition according to the duration of the current task.

[0039] The manual entry of the electronic student ID card 24 into the motion data acquisition mode described in this example means that the user activates the positioning circuit 7 and the acceleration sensor through the button 15 of the electronic student ID card 24 or the touch screen 11 on the main body of the ID card 2 to complete the acquisition of motion data.

[0040] The electronic student ID 24 automatically enters the motion data acquisition mode, which means that: the accelerometer in the electronic student ID 24 detects the user's motion state. When the accelerometer continuously detects that the user is not stationary (for example, the accelerometer counts steps, and when the number of steps taken by the user exceeds a set threshold within a set time interval (such as within 1 minute, the set threshold can be 100 steps), it is considered that the user is currently in motion. The main controller outputs the prompt message "Are you in motion?" through the touch screen of the ID card body. The prompt message "Are you in motion?" can be broadcast through the speaker in the voice input and output circuit, or it can be prompted by a vibration motor that can output vibration signals to prompt the user to confirm the information in time. When the user confirms the information, the motion data acquisition mode is entered.

[0041] In non-classroom mode or standby mode, if the electronic student ID card 24 detects that the student has not made any exercise judgment within a set time period, such as 2 hours, it will issue an exercise reminder (You've been studying hard! Get up and exercise!). Clicking the back button will turn it off. If you want to start exercising, click to enter the exercise interface.

[0042] In this example, the front end of the male or female connector of the magnetic connector connected to the accessory circuit is exposed inside the housing cavity 3, while the male or female connector of the magnetic connector connected to the functional circuit is exposed on the outer shell of the document body 2.

[0043] As attached Figure 8 As shown, the functional circuit described in this example includes a main controller 6, a positioning circuit 7, a power supply circuit 8, a touch display circuit 9, and a voice input and output circuit 10. The main controller 6 is connected to the positioning circuit 7, the power supply circuit 8, the touch display circuit 9, and the voice input and output circuit 10. The front of the document body 2 is provided with a touch screen 11, which is connected to the touch display circuit 9. The document body 2 is also provided with a power button 12, which is connected in series in the power supply circuit 8. The voice input and output circuit 10 is provided with a microphone and a speaker 21. The main controller 6 and the power supply circuit 8 are connected to the male or female connector 20 of the magnetic connector provided on the document body 2.

[0044] The accessory circuit includes a button circuit 13 and a TYPE-C interface circuit 14. One end of the button circuit 13 is connected to the female or male connector of the magnetic connector 5 on the card-type body 1, and the other end of the button circuit 13 is connected to the button 15 on the card-type body 1. The TYPE-C interface circuit 14 is connected to the female or male connector of the magnetic connector on the card-type body 1. In this example, the accessory circuit also includes a charging circuit 16, which has a lithium battery with one end connected to the female or male connector of the magnetic connector on the card-type body 1. The lithium battery is also connected to the TYPE-C interface circuit 14.

[0045] The depth of the housing cavity 3 of the card-type main body 1 is the same as the thickness of the document body 2. In order to ensure the stability of the fitting, a silicone pad layer is provided on the housing cavity 3 to increase the friction with the document body 2. The upper port edge of the housing cavity 3 is chamfered, and the inner diameter of the upper port edge is slightly smaller than the maximum outer diameter of the document body. The outer edge of the document body 2 has rounded chamfers to facilitate quick insertion when it is interference-fitted with the housing cavity 3.

[0046] Furthermore, in order to ensure that the document body 2 can be quickly removed from the card-type body 1, the back of the housing cavity 3 of the card-type body 1 is provided with a hollow part, which makes it easy to push the document body out of the housing cavity through the hollow part.

[0047] The housing of the document body 2 described in this example is also provided with a connecting part 17 for connecting a watch strap, and a groove is provided on the housing cavity 3 of the card-type body 1 to accommodate the connecting part 17; the card-type body 1 is provided with a push button 18 corresponding to the power button 12 of the document body 2. When the document body 2 is fitted into the housing cavity 3, the push button 18 is opposite to the power button 12 of the document body 2. When the push button 18 is pressed, the power button 12 can be pressed at the same time to complete the power on / off operation; the card-type body 1 is also provided with a lanyard hole 19 for connecting a lanyard.

[0048] In use, depending on the wearer's situation, the main body 2 of the ID card is embedded into the housing cavity 3 of the card-type main body 1 to form a card-type electronic student ID card, or the main body 2 is connected to the watch strap 22 and fixed on the user's wrist. When the main body 2 is embedded into the housing cavity of the card-type main body 1, the functional circuit in the main body 2 is electrically connected to the accessory circuit via the magnetic connector 5. At this time, the button circuit 13 in the accessory circuit can send a pressing signal to the button 15 on the card-type main body 1 to the main body 2, and the lithium battery in the charging circuit 16 in the accessory circuit can charge the main body 2. When the TYPE-C interface circuit 14 in the accessory circuit is connected to an external charging device, it can simultaneously charge both the lithium battery in the accessory circuit and the main body 2, thereby improving the device's battery life. This invention can also perform motion data acquisition through the functional circuit located within the main body and interact with an external host computer platform under various wearing conditions.

[0049] Specifically: the host computer 23 receives the motion data uploaded by the electronic student ID card 24, and stores and analyzes it; the electronic student ID card 24 is used to collect student motion data, wherein the positioning circuit and acceleration sensor on the electronic student ID card 24 collect the user's motion data.

[0050] The electronic student ID card 24 has a campus sports app installed. By clicking the button on the screen, a prompt message ("Start exercising now!") and exercise confirmation information ("OK") are displayed at the top of the screen. If the exercise information is confirmed by clicking the button, the student ID card enters the exercise mode. The student ID card increases the frequency of GPS positioning chip collection (collecting once every 5 seconds). The campus sports app receives GPS information from the positioning chip and saves the GPS movement track. The campus sports app also receives step count information reported by the accelerometer. When the exercise ends, clicking the campus sports app again will display the exercise end time (year-month-day hour:minute), number of steps (XXX steps), exercise duration (XXminXXs), total distance (XXX kilometers), and calories (XXXkcal). Clicking the button will return to the exercise homepage.

[0051] The campus sports app on the electronic student ID 24 can also receive morning exercise tasks issued by the host computer 23. The morning exercise task includes the morning exercise time (X:xx-Y:yy). Two minutes before the start time of the morning exercise, the campus sports app will pop up a reminder (The early bird catches the worm, it's time to exercise! Start exercising now!). You can close it by clicking the back button. If you start exercising, you can click to enter the exercise interface. If you start exercising during the morning exercise time, the first time you start exercising during the morning exercise time will be the start time. If you do not finish exercising by the end time, it will be forcibly terminated.

[0052] In non-classroom mode and standby mode, if the device detects that the student has not made any movement judgment within 2 hours, it will issue an exercise reminder (You've been studying hard! Get up and move around!). You can turn it off by clicking the back button. If you want to start exercising, click to enter the exercise interface.

[0053] If a student enters the exercise mode without clicking the campus sports app on their electronic student ID 24, and the student ID's accelerometer detects that the student's speed exceeds a first threshold (100 steps / minute), the campus sports app will prompt the student to confirm "Enter exercise mode?" via voice announcement and vibration. Specifically, the "Are you in exercise mode?" prompt can be output through a speaker in the voice input and output circuit, or it can be prompted by a vibration motor that can output vibration signals. If the student has already started exercising, they can click to enter the exercise interface; otherwise, they can click the back button to close the app. The campus sports app on the electronic student ID 24 will include the exercise data before entering exercise mode in the exercise data.

[0054] Compared with traditional electronic student ID cards, this invention can significantly reduce the product size by housing the accessory circuitry and charging circuitry on the card-shaped main body. While ensuring the basic requirements of the main body's battery life, it makes the card easier to carry during running and jumping activities. It has significant advantages such as reasonable structure, easy assembly and disassembly, and flexible use.
