The invention discloses a motion monitoring method and system based on a micro-nano-level three-axis acceleration sensor. The method includes: obtaining user characteristic parameters, and then calculating the user's running step length; collecting user's arm swing angle data, and obtaining The user's arm swing angle window; according to the arm swing angle window, monitor the number of running steps during the user's running process, and measure the duration of the user's running process; according to the obtained duration, number of running steps and running Step length, calculate running distance and running speed. The system includes a microprocessor, keys, an electronic paper display and a three-axis acceleration sensor. The present invention can perform calculations according to the actual conditions of different individuals, greatly improving the accuracy, so that users can clearly understand their own exercise status during running, thereby customizing their own running plans or improving exercise efficiency, etc., to improve human health the goal of. The invention can be widely applied in the field of motion monitoring.
Description
technical field [0001] The invention relates to the field of motion monitoring, in particular to a motion monitoring method and system based on a micro-nano level triaxial acceleration sensor. Background technique [0002] The early running pedometers used aggravated mechanical switches to detect steps, that is, when a counterweight vibrated up and down, the balance was destroyed to make a contact appear on / off, and then a simple counter recorded and displayed the number of steps. Known as a mechanical pedometer. This pedometer has a simple structure, but because it must be hung on the waist in a vertical manner, if the position is wrong, the step counting is very inaccurate, and it has been eliminated at present. [0003] For some pedometers now, although a three-axis acceleration sensor is also used, the formula method and the acceleration threshold method are mainly used. The advantage of this algorithm is that it can directly obtain the instantaneous speed, but the acc...
