Embodiment Construction
[0016] In the use of this acceleration measurement device, after the three-dimensional acceleration sensor receives the sound signal, it starts to sense the movement of the athlete, and converts the change of movement into a change of voltage, and then is amplified, filtered and conditioned by the measurement circuit, A / D analog-to-digital converter conversion, etc., and finally processed by the single-chip system to store and display the data. The three-dimensional direction acceleration information acquisition and processing circuit mainly uses the single chip microcomputer to realize the simultaneous measurement and acquisition of the athlete's three-dimensional direction movement acceleration through its capture channel. The measuring device has a reasonable structure, is stable and reliable, and can collect data for a long time. It is suitable for the acceleration measurement of motion and the teaching measurement of mechanics, electronic technology and other courses in c...

The invention relates to a three-dimensional acceleration measuring device and a three-dimensional acceleration measuring method, providing the three-dimensional acceleration measuring device and thethree-dimensional acceleration measuring method which combine with a liquid crystal display screen, a three-dimensional acceleration sensor and a singlechip control circuit. The three-dimensional acceleration measuring device is composed of an acceleration measurement circuit box and an elastic fixing buckle ring, after receiving a sound signal, the three-dimensional acceleration sensor begins tosense the movement of an athlete, and converts the variation of the movement into the variation of voltage, after amplification of a measuring circuit, smoothing and conditioning of sensing signals, and converting of an A / D analog-digital converter, a singlechip system performs treatment, and stores and displays data. According to the three-dimensional acceleration measuring device and the three-dimensional acceleration measuring method, through acquiring, processing and displaying for three-dimensional acceleration signals, the convenient collection and storage for acceleration data are realized, the measuring device is reasonable in structure, the measuring method is stable and reliable, long-time collection for data can be realized, and the device and the method are suitable for acceleration measurement of movement and teaching measurement of the courses including mechanics, electronic technology and the like of colleges and universities.
Description
technical field [0001] The invention relates to a three-dimensional acceleration measuring device and method, belonging to the technical fields of kinematics, mechanics and electronics measurement. Background technique [0002] The application of acceleration sensors in sports can be used to obtain information such as the speed and strength of athletes, and can measure the reaction ability and acceleration of athletes, which is of great help to the training of athletes. [0003] In the past, the determination of the athlete's response ability was mostly through a simple method of measuring the acousto-optic reaction time, or through a computer simulation method to test the athlete's response ability. However, these test methods are greatly affected by the external environment and people's subjective psychological factors, and have large errors, which cannot accurately and objectively reflect the ability of athletes' neural responses in sports. [0004] The three-dimensional...
