Embodiment 1

[0024] An embodiment of intelligent curling that can collect its own motion parameters in real time, see figure 1 , figure 2 and image 3 , the smart curling includes a curling body 1, the curling body is provided with a curling handle 2, wherein an interlayer 3 is arranged between the curling body and the curling handle, and a data acquisition device is arranged in the interlayer. module, the data acquisition module includes an angular velocity sensor 4 called a gyroscope, an acceleration sensor 5, a central processing unit 6, a time generator 7 and a wireless transmission circuit 8, and the angular velocity sensor and the acceleration sensor are all arranged on the curling The central position of the body, the angular velocity sensor and the acceleration sensor are respectively connected to the central processing unit through the A / D conversion circuit 9, and the central processing unit is connected to the time generator and the wireless transmission circuit line, and the ...

Embodiment 2

[0031] This embodiment is a specific embodiment. The size and shape of the smart curling jug are basically the same as those of the commonly used curling jug, which is an ellipsoid with a concave upper surface and a lower surface. Its circumference is about 91.44 cm, its height is about 13.43 cm, and its weight is about 20 kg. According to the needs of actual users, its size and shape can be adjusted within the range specified by the World Curling Federation (ICF).

[0032] In this embodiment, the smart curling is obtained by transforming an original curling. The components of the mechanical structure of intelligent curling include the kettle body, the handle assembly, the kettle bolt (the vertically long bolt connecting the kettle body and the handle) and the disc-shaped interlayer shell, of which the kettle body, the handle assembly and the kettle bolt are original The component parts of curling, the interlayer shell is a new device specially designed and manufactured. The...

Embodiment 3

[0042] A method for collecting and processing motion state data of curling during the entire exercise process based on the intelligent curling, comprising the intelligent curling described in Embodiment 1 and a wireless signal receiving and processing device, and three Axis magnetometer, in which, during the whole process of the smart curling being slid from the preliminary static state to throwing by the throwing hand, and then to the stop of motion, the angular velocity of the curling itself relative to the inertial space is continuously collected at a certain frequency data, acceleration data, and the orientation angle data of the curling relative to the geomagnetic field, the three kinds of data collected are added with the sampling time timestamp and sent to the wireless signal receiving and processing device, and the wireless signal receiving and processing device adopts the The joint inertial navigation algorithm obtains the angular velocity and acceleration of the smart...

Abstract

The invention relates to an intelligent curling capable of collecting motion parameters in real time and a method thereof. The intelligent curling capable of collecting the motion parameters in real time comprises a curling body and a curling handle, wherein an interlayer is arranged between the curling body and the curling handle, a data acquisition module is arranged in the interlayer, the data acquisition module comprises an angular velocity sensor which is also called gyroscope, an acceleration sensor, a central processing unit, a time generator and a wireless transmission circuit, the angular velocity sensor and the acceleration sensor are arranged at the central position of the curling body and connected with the central processing unit through analog to digital (A / D) switching circuits, and the central processing unit is in wired connection with the time generator and the wireless transmission circuit. According to the intelligent curling capable of collecting the motion parameters in real time, the structure is compact, automatic collection of motion state data of the curling is achieved without changing of the application method of an existing curling, a real-time and quantized basis is provided for evaluation of motion states of the curling, and technical levels of a coach and an athlete are improved.

Description

technical field [0001] The invention relates to the field of sports data collection, in particular to an intelligent curling machine capable of collecting its own motion parameters in real time and a method thereof. Background technique [0002] In curling, athletes use curling as a medium for team confrontation. Whether the control of the curling track is accurate or not reflects the level of the athlete's technical level, and also directly affects the final outcome of the game. Therefore, how to more precisely and comprehensively detect the kinematic characteristics of curling on the ice track has become a problem of great concern to coaches and athletes. [0003] A typical scenario is: because the opponent has placed a blocking stone in front of the camp, subsequent curling stones cannot reach the intended destination along a straight line path, so the thrower needs to accurately throw a curling stone that travels along an arc-shaped path , so as to be able to bypass th...
