Embodiment 1

[0046] This embodiment provides an information sampling method for a wearable device, such as figure 1 As shown, the steps include:

[0047] S1: Obtain the information value of the sampled information;

[0048] S2: Calculate and analyze the range range of the sensor to which the information value of the sampled information belongs;

[0049] S3: According to the measuring range of the sensor to which the information value of the sampled information belongs, select the sensor corresponding to the measuring range.

[0050] A wearable device is a portable device that is worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not only hardware devices in the city, but also realize powerful functions through software support, data interaction, and cloud interaction. Using sensors to sample signals can realize the function of collecting user information.

Embodiment 2

[0064] This embodiment provides an information sampling method for a wearable device, such as image 3 shown; image 3 It is another flowchart of an information sampling method of a wearable device in the present invention. This embodiment includes steps:

[0065] S41: Obtain the information value of the sampling information;

[0066] S42: judging whether the information value of the sampled information reaches the threshold;

[0067] S43: If the two sensors corresponding to the adjacent ranges are turned on, the threshold value is turned on;

[0068] S44: Receive the information value of the sampled information in the second preset time period;

[0069] S45: judging whether the ratio of the information value of the sampling information in the second preset time period exceeding the smaller range exceeds the preset ratio;

[0070] S46: If the small-range sensor is turned off, the large-range sensor is used; if the large-range sensor is not turned off, the small-range sens...

specific Embodiment approach

[0071] The measurement range described in this embodiment, that is, the measurement range of the sensor, refers to the sampling range of the sensor for the information value of the sampled information. Generally, when a sensor is used, only one range can be selected, and the corresponding range of different sensors It can be different, for example, the range of sensor A is [a, b], the range of sensor B is [b, c], and the corresponding range of sensor C is [c, d]. Therefore, sensor A, sensor B, and sensor C can be used to measure the sampling signal with interval [a,d]. When the information value of the sampled information is at the critical value of the two sensors, the corresponding most accurate sensor can be found by calculating the range interval ratio. The specific implementation is as follows:

[0072] The critical state of the two ranges of the sensor, the critical state is the range preset according to the sensor range, when the information value of the sampled inform...

Abstract

The invention discloses wearable equipment and an information sampling method, which are used for solving the problem in the prior art that sensor range is set to be relatively large, thus measuring accuracy is relatively low. The method includes the steps of S1. obtaining an information value of sampled information; S2. calculating and analyzing the measuring range of a sensor to which the information value of the sampled information belongs; and S3. according to the measuring range of the sensor to which the information value of the sampled information belongs, selecting the sensor corresponding to the measuring range. By adoption of the information sampling method, redundant sensors can be additionally arranged on the basis of a single sensor adopted at present, different precision and measuring ranges are set for the sensors according to different requirements, an appropriate sensor is judged through an algorithm, the inappropriate sensors are temporarily turned off, and thus power consumption can be guaranteed not to increase while accurate data can be obtained.

Description

technical field [0001] The invention relates to the field of sensor information sampling, in particular to a wearable device and an information sampling method thereof. Background technique [0002] A wearable device is a portable device that is worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not only hardware devices in the city, but also realize powerful functions through software support, data interaction, and cloud interaction. They use sensors to sample signals to realize the functions we need, which brings great benefits to our life and perception. change. [0003] Current wearable devices basically only use an accelerometer, a magnetometer and a gyroscope, and use these sensors to calculate the number of steps, heat, orientation, etc. through some algorithms. The general approach is to collect data, do some data processing on the data, and then send it to the upper layer for further calculations, which can improv...
