Problems solved by technology

The disadvantage of this method is that the acceleration on the main direction axis is not necessarily the actual acceleration, and there may be a big difference, so the calculation will easily lead to inaccurate results

Embodiment

[0017] The step counting method based on the three-axis accelerometer described in this embodiment, as attached figure 1 As shown, by obtaining the real-time acceleration values ​​of the x-axis, y-axis, and z-axis of the three-axis accelerator, the acceleration values ​​​​of the three direction axes are obtained; the acceleration values ​​​​of the three direction axes are used to calculate the combined acceleration value; through the combined acceleration value , calculate the actual acceleration value; through the actual acceleration value, compare the preset positive threshold and negative threshold to obtain real-time motion status information; and then analyze the step status information through the real-time motion status information to realize the step counting function.

[0018] The real-time acceleration values ​​of the x-axis, y-axis and z-axis are respectively the length values ​​of the real-time coordinate vectors of the x-axis, y-axis and z-axis; the resultant accel...

Abstract

The invention discloses a step counting method based on a triaxial accelerator, and relates to the field of sensor step counting methods. The real-time acceleration values of the triaxial accelerator on the x-axis, the y-axis and the z-axis are acquired, and the values of acceleration of the three direction axes are acquired; a sum acceleration value is calculated through the values of acceleration of the three direction axes; an actual acceleration value is calculated through the sum acceleration value; a preset positive threshold value and negative threshold value are compared through the actual acceleration value, and real-time motion state information is obtained; step state information is obtained by analyzing the real-time motion state information, and the step counting function is achieved. The step counting function can be achieved only through one sensor, namely, the triaxial accelerator, the advantages that the data acquiring speed is high, calculation is easy, convenient and high in efficiency, and the result accuracy is high are achieved, and good actual application and popularization value is achieved.

Description

technical field [0001] The invention relates to the field of sensor step counting methods, in particular to a step counting method based on a three-axis accelerator. Background technique [0002] With the development of science and technology and the arrival of the era of smart electronics, people can intuitively, accurately and clearly observe their own body status information through a variety of smart electronic devices, among which the number of steps taken by walking or running is one of them. People plan their daily exercise by recording their exercise steps. The number of steps is an indicator for measuring the amount of walking or running, and the step counting function has been widely used in the application of various smart electronic devices. [0003] At the same time, as a sensor, the triaxial accelerator has already been integrated in most wearable smart devices. The three-axis accelerometer can measure the acceleration of human motion in the three direction a...
