Embodiment Construction

[0026] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0027] figure 1 It is a flow chart of the method of the present invention, and the specific content will not be repeated here.

[0028] The technical scheme of the present invention is further elaborated below by specific embodiment:

[0029] First of all, when the user starts counting, it needs to train for a period of time to obtain the sampling frequency of the acceleration sensor on the Android phone. Here, the starting time t is recorded. s . Start to receive the acceleration data from the acceleration sensor, and record 50 data. When 50 data records are completed, record the end time t at the same time e . According to the starting time t s and end time t e The sampling frequency f of the acceleration sensor of the mobile phone can be calculated, f=1000 / (t e -t s )*50.

[0030] Secondly, after determining the sampling frequency of t...

Abstract

The invention discloses a method for realizing a pedometer on an Android mobile phone. The Android mobile phone is held by a hand or is placed in a pocket, an acceleration sensor on the Android mobile phone is used for acquiring data, accelerated speed is subjected to a series of processing and the purpose of counting the walking steps can be achieved finally. The method comprises the steps of determining the sampling frequency and a time window of the acceleration sensor of the mobile phone; carrying out denoising on the acquired data, extracting the normal walking characteristic by k-means according to the denoised data; and counting the walking steps of a person in the time window according to the characteristics and the denoised data. According to the method, the walking steps can be counted by the Android mobile phone and effective technical support and rational suggestion can be provided for the healthy life and the sports of the person.

Description

technical field [0001] The invention relates to a method for realizing a pedometer on an Android mobile phone, in particular to the collection, processing and application technology of acceleration sensor data of the mobile phone, and belongs to the field of sensor application and information technology. Background technique [0002] With the development of technology, Android phones have been gradually popularized and integrated into people's lives. And people's health problems and physical exercise problems are getting more and more people's attention. How to monitor people's health and exercise conditions more conveniently has become the focus of people's attention. At present, there are also many softwares that use smart phones to monitor people's physical exercise, which provides strong material and technical support for health monitoring and exercise guidance, and also has a good market prospect. [0003] There are many devices for counting people's walking steps at p...
