Description

Technical Field

[0001] The invention relates to the technical field of billiard sports, and in particular to an intelligent device for monitoring billiard cueing movements and postures. Background Art

[0002] Billiards, also known as table tennis (the name in Guangdong, Hong Kong and Macao) and pool (the name in Taiwan, China), is an elegant indoor sport that is widely popular internationally.

[0003] Nowadays, more and more people love to play billiards, but fans cannot intuitively understand their cueing habits and postures when playing billiards, nor do they know how much force is reflected when hitting the billiard ball at what speed; in order to better improve the competitive level of billiards and improve the problem of deformation of the cueing action, there is a demand for fans: there is a thing that can directly measure the change of the cueing speed when hitting the ball and intuitively understand the changes in the cueing and cueing posture when hitting the billiard ball, so as to improve the competitive level of billiards. Therefore, it is necessary to study an intelligent device that can record the speed changes during the cueing process and whether the posture is correct in real time. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an intelligent device for monitoring billiards cue action and posture. The device can accurately detect the speed of the cue when hitting the ball, accurately detect the posture changes of the cue during the entire movement process of the cue, and accurately measure the posture changes of the arm swing, so as to provide reference data for users to understand their own cueing habits and the magnitude of the force of different speed reactions, which is helpful to correct incorrect cueing postures and improve the competitive level of billiards.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: an intelligent device for monitoring billiard cue action and posture, comprising: a key function detection module, a power management module, a motion data acquisition module, a main controller module with a wireless transmission function, a monitoring position one (a1) of the device, a monitoring position two (a2) of the device, and a monitoring position three (a3) ​​of the device, wherein the key function detection module, the power management module and the motion data acquisition module are respectively connected to the main controller module with a wireless transmission function;

[0006] The button function detection module is used to detect whether the current operation is to start up, shut down or calibrate the motion data acquisition module;

[0007] The power management module is used to detect battery power information and has overcurrent, overcharge, overdischarge and short circuit protection functions;

[0008] The motion data acquisition module is used to collect the motion data of the club or arm and the posture changes in real time, and is designed to be low-power by combining the key function detection module, the power management module, and the main controller module with wireless transmission function;

[0009] The main controller module with wireless transmission function is connected to each module respectively. The main controller receives the information of the motion data acquisition module, analyzes it through the internal algorithm, records the real-time motion data and posture data, and transmits the motion and posture data to the mobile terminal through the wireless transmission medium for graphical interface display;

[0010] The monitoring position one (a1) of the device is used to monitor the club's movement and release movements and posture changes;

[0011] The monitoring position two (a2) of the device is used to monitor the movement and posture changes of the forearm;

[0012] The monitoring position three (a3) ​​of the device is used to monitor the movement and posture changes of the upper arm.

[0013] Furthermore, the key function detection module uses two main controller IO ports for control, which are named IO1 and IO2 respectively; IO1 is connected to the key and the enable end of the LDO chip through a resistor, and IO2 is connected to the enable end of the LDO chip through a resistor. IO1 is used to detect whether the key is pressed. In the shutdown state, if the key is pressed, the enable end of the LDO chip is in a high-level enable state, so that the LDO outputs 3.3V to power the system. After the system is running, the main controller will continue to detect the state of IO1. If it is detected that IO1 has been at a high level for a period of time, it means that the key has been pressed. The main controller will set IO2 to a high level, continue to maintain the enable state of LDO, power the entire system, and complete the startup operation; during normal operation, if the key is pressed twice quickly, the system will enter the motion data acquisition module calibration mode; during normal operation, if the key is pressed continuously for a period of time, the main controller will set IO2 to a low level, so that the LDO enters a disabled state, no longer outputs 3.3V power to the system, and completes the shutdown operation.

[0014] Furthermore, the power management module uses a battery power management chip and a battery protection chip. The battery power management chip can set the charging current through an external resistor and automatically end the charging process when it is fully charged. The battery protection chip can protect the battery to avoid over-discharge and short circuit.

[0015] Furthermore, the motion data acquisition module uses an MPU6050 chip, which can record the current acceleration and gyroscope data. Combined with the internal algorithm, it can know the acceleration process of the current speed and the current posture position. By setting the motion interrupt mode, when no obvious change in acceleration is detected for a long time, the main controller will enter a low power mode. When it is detected that the acceleration exceeds the set threshold, an external interrupt is generated to wake up the main controller in low power mode.

[0016] Furthermore, the main controller module with wireless transmission function, combined with other modules, controls the device to execute corresponding functions, internally records and analyzes the data information of the current motion acquisition module in real time, and calculates the speed information of the current motion through the internal algorithm. If it is detected that the current action is a batting action, the relevant data information is sent to the mobile terminal through the Bluetooth link layer for graphical interface display.

[0017] Furthermore, the monitoring position 1 (a1) of the device is a fixed monitoring point for the purpose of monitoring the movement of the golf club. The monitoring position is fixed at the bottom of the golf club, and the current movement data and posture information can be detected as the golf club moves.

[0018] Furthermore, the monitoring position two (a2) of the device is a fixed monitoring point for the purpose of monitoring the swing of the forearm. The monitoring position is fixed on the outside of the forearm, and the current motion data and posture information can be detected as the forearm swings.

[0019] Furthermore, the monitoring position three (a3) ​​of the device is a fixed monitoring point for the purpose of monitoring the swing of the boom. The monitoring position is fixed on the outside of the boom, and the current motion data and posture information can be detected as the boom swings.

[0020] The beneficial effects of the present invention are: the smart device can accurately identify whether the current action is a hitting action, and transmit the relevant motion data and posture data to the mobile device via Bluetooth for graphical interface display; the device can be set to enter different working modes according to different monitoring points, and can respectively monitor the motion behaviors of the club, forearm and upper arm, analyze the current motion data and posture data, and facilitate users to perform all-round motion posture detection to improve the user's competitive level.

[0026] The present invention will be further described in detail below in conjunction with embodiments and drawings to fully demonstrate the usage details and effects.

[0027] Example:

[0028] like Figure 1 As shown, this embodiment provides an intelligent device for monitoring billiard cueing action and posture, including: a key function detection module, a power management module, a motion data acquisition module, and a main controller module with a wireless transmission function. The key function detection module, the power management module, and the motion data acquisition module are respectively connected to the main controller module with a wireless transmission function. The specific description is as follows:

[0029] 1. Key function detection module

[0030] like Figure 2 As shown, the key function detection module uses two main controller IO ports for control, which are named IO1 and IO2 respectively; IO1 is connected to the key and the enable end of the LDO chip through a resistor, and IO2 is connected to the enable end of the LDO chip through a resistor. IO1 is used to detect whether the key is pressed. In the shutdown state, if the key is pressed, the enable end of the LDO chip is in a high-level enable state, so that the LDO outputs 3.3V to power the system. After the system is running, the main controller will continue to detect the state of IO1. If it is detected that IO1 has been at a high level for a period of time, it means that the key has been pressed. The main controller will set IO2 to a high level, continue to maintain the enable state of LDO, power the entire system, and complete the startup operation; during normal operation, if the key is pressed twice quickly, the system will enter the motion data acquisition module calibration mode; during normal operation, if the key is pressed continuously for a period of time, the main controller will set IO2 to a low level, so that the LDO enters a disabled state, and no longer outputs 3.3V power to the system, completing the shutdown operation.

[0031] 2. Power Management Module

[0032] like Figure 3As shown, the power management module can adjust the charging current by adjusting the size of the resistor R6. When the battery voltage is close to 4.2V, the charging current gradually decreases. When it decreases to 10% of the constant current charging current, the charging process is automatically terminated. When a short circuit occurs in the internal circuit, the OD pin of the U9 chip will be triggered to output a low level. At this time, Q1 is in a disconnected state, which plays a role in short-circuit protection of the battery.

[0033] 3. Motion Data Collection Module

[0034] like Figure 4 As shown, the motion data acquisition module uses the MPU6050 chip, which integrates a three-axis accelerometer and a three-axis gyroscope. The chip is connected to the main controller via an IIC bus. The acceleration data and gyroscope data collected in real time are transmitted to the main controller through this bus for analysis. The INT hardware of the MPU6050 is connected to the IO of the main controller. When it is detected that the acceleration data exceeds a preset threshold, INT will generate an external interrupt to wake up the main controller in low power mode.

[0035] 4. Main controller module with wireless transmission function

[0036] The main controller module with wireless transmission function uses the NRF52832 chip. Combined with other modules, it controls the device to execute corresponding functions, records and analyzes the data information of the current motion acquisition module in real time, and calculates the speed information of the current motion through the internal algorithm. If it is detected that the current action is a batting action, the relevant data information is sent to the mobile terminal through the Bluetooth link layer for graphical interface display.

[0037] 5. Equipment monitoring positions a1, a2, a3

[0038] like Figure 5 As shown, the monitoring position one (a1) of the device is to fix the device to the bottom (a1) of the club (a) through a silicone sleeve, enter the corresponding working mode, and through the motion data acquisition module and internal algorithm analysis, the speed change and posture change of the club can be solved in real time and recorded. The internal algorithm can perform real-time analysis. If it is determined that it is a hitting behavior, then these data will be sent to the mobile terminal through the wireless transmission module and displayed on a graphical interface;

[0039] The second monitoring position (a2) of the device is to fix the device to the outer side (a2) of the forearm through the wristband, enter the corresponding working mode, and calculate the current posture of the forearm in real time through the motion data acquisition module and the internal algorithm analysis, and calculate whether the current position is deviated from the ground plane and the vertical plane perpendicular to the ground plane. The main controller records the size of the deviation in real time and sends it to the mobile terminal through the wireless transmission module to display it in a graphical interface;

[0040] The monitoring position three (a3) ​​of the device is to fix the device to the outer side (a3) ​​of the upper arm through a wristband and enter the corresponding working mode. Through the motion data acquisition module and internal algorithm analysis, the current posture of the upper arm can be solved in real time, and it is calculated whether the current position deviates from the ground plane and the vertical plane perpendicular to the ground plane. The main controller records the size of the deviation in real time and sends it to the mobile terminal through the wireless transmission module for display on a graphical interface.

[0041] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the scope disclosed by the present invention, which are all within the protection scope of the present invention.
