Embodiment 1

[0116] The method of embodiment one can also refer to Figure 15 . Figure 15 The method of Embodiment 1 is shown more intuitively in the manner of cascading steps.

[0117] By adopting the method provided by the embodiment of the present invention, abnormal step counting can be effectively reduced, and the monitoring of the user's activity amount can be made more accurate. If the first specific eigenvalue λ 1 It is used to detect the vibration signal generated by the hand crank and the vibration signal generated by the hand winding, the second specific eigenvalue λ 2 It is used to detect the vibration signal generated by the simple pendulum, and the third specific eigenvalue λ3 is used to detect the vibration signal generated by shaking the leg. Adopt the method that the embodiment of the present invention provides, in the actual 30 person-time tests, can detect 95% of the wrong steps counted by hand winding, 95% of the wrong steps counted by the single pendulum, fast hand...

Abstract

The present invention relates to the technical field of automatic control, particularly to a step counting method, a step counting apparatus and a pedometer, such that the problem that the existing pedometer can not recognize the abnormal situation and produces the step counting error can be solved. In the step counting method provided by the embodiments of the present invention, a vibration signal output by a step counting sensor is received, at least one of specific characteristic values of the received vibration signal and the preset threshold value of the same specific characteristic value for representing the vibration signal produced by stepping are compared, and the step counting is discarded when the abnormal step counting is determined according to the comparing result, wherein the vibration signal capable of being characterized and received by the specific characteristic value and the vibration signal produced by stepping are different when the received vibration signal is the vibration signal produced by non-stepping. In addition, in the method, the abnormal step counting is determined according to the specific characteristic value of the vibration signal output by the step counting sensor, such that the step counting error can be avoided.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a step counting method, a step counting device and a pedometer. Background technique [0002] Human walking is a quasi-periodic process, and the vibration generated by the human body in this process is also quasi-periodic. Existing pedometers are all based on the above-mentioned principle. Vibration signals are detected by sensors, and a quasi-period in the vibration signals that satisfies a certain amplitude and duration is recognized as a step and counted. [0003] However, the vibration signal detected by the sensor in the pedometer is not necessarily caused by the user’s walking, and may also be caused by other reasons, such as: shaking the pedometer in the hand (hand shake), tying the pedometer with a rope and Make it do a circular motion (hand winding), hang the pedometer on the rope and do a pendulum movement (single pendulum), and shake the legs slightly (shaki...
