Embodiment 1

[0020] figure 1 Is a flowchart of a step counting method according to an embodiment of the present invention, such as figure 1 As shown,

[0021] In step S110, the three-axis acceleration data of the current sampling point within a certain period of time is acquired, and the idle state judgment is performed according to the acquired three-axis acceleration data;

[0022] In step S120, if it is determined to be in an idle state, it enters the search mode and continues to obtain the three-axis acceleration data of the new sampling point; if it is determined to be in a non-idle state, the total acceleration of the three-axis acceleration data is calculated, where the total acceleration Is the square root of the sum of squares of the three-axis acceleration data;

[0023] In step S130, judge whether the current sampling point is a possible pedometer according to the total acceleration, if the judgment is no, continue to obtain the three-axis acceleration data of the new sampling point; i...

Embodiment 2

[0101] Figure 4 It is a structural diagram of a pedometer device according to an embodiment of the present invention, such as Figure 4 As shown, a pedometer device is characterized in that the device 200 includes a memory 220 and a processor 210, the memory 220 stores a computer program that can be executed by the processor 210, and the computer program is The processor 210 can implement such as figure 1 The method steps shown.

[0102] The memory 220 and the processor 210 are communicatively connected through an internal bus 230. In an embodiment of the present invention, the memory 220 stores a step-counting computer program 221. The step counting computer program 221 can be executed by the processor 210 as figure 1 The method steps shown.

[0103] In different embodiments, the memory 220 may be a memory or a non-volatile memory. The non-volatile memory may be: a storage drive (such as a hard disk drive), a solid state hard disk, any type of storage disk (such as an optical di...

Embodiment 3

[0106] A wrist pedometer, characterized in that, the wrist pedometer 300 includes such as Figure 4 The step counter 200 is shown.

[0107] It should be noted that the working process of the wrist pedometer 300 claimed in this embodiment is the same as figure 2 The working process of the pedometer device 200 shown corresponds to the same, and the same parts will not be repeated.

[0108] It should be noted that the wrist pedometer can be a wearable device such as a smart watch or a smart bracelet. The wrist pedometer has reliable and accurate step counting performance in various application scenarios.

[0109] Wearable devices have limited resources, and need to consider the amount of calculation and power consumption. The continuous monitoring of the pedometer needs to consume a lot of energy. The technical scheme of the present invention adopts an effective strategy to reduce the complexity of the algorithm, reduce the amount of calculation, and improve the efficiency.

Abstract

The invention discloses a step counting method and device and a wrist type pedometer. The method comprises steps as follows: triaxial acceleration data of a current sampling point in a certain period of time is acquired and idle state judgment is performed; if a user is in the idle state, a search mode is started; if the user is in the non-idle state, resultant acceleration of the triaxial acceleration data is calculated; whether the current sampling point is a possible step counting point is judged according to the resultant acceleration, if the current sampling point is not the possible step counting point, triaxial acceleration data of a new sampling point is acquired continuously, if the current sampling point is the possible step counting point, whether the current mode is a step counting mode is judged, and if the current mode is the step counting mode, step counting is performed; if the current mode is the search mode, possible step counting points are cached, the cached possible step counting points are subjected to true pace verification, if the possible step counting points are true paces, the current mode is switched into the step counting mode, and step counting is performed; if the possible step counting points are not true paces, the current mode is switched into the search mode. Accurate step counting can be realized through repeated verification.

Description

Technical field [0001] The invention relates to the field of computer technology, in particular to a pedometer method, device and wrist pedometer. Background technique [0002] In recent years, as people gradually pay more attention to their own health conditions, equipment that provides exercise monitoring and tracking functions has been rapidly developed. Among them, walking is the most basic form of exercise for people, providing a reliable step counting method can quantify the user's exercise and realize the user's self-monitoring. On the other hand, the rise of wearable devices such as smart watches and bracelets provides a good platform for the realization of pedometer functions. They have programmability and embed a variety of low-cost MEMS sensors. Acceleration sensor, etc. to track the user's movement and realize the step-counting function. [0003] At present, step counting methods based on acceleration sensors can be divided into three main categories: one is a judgmen...
