Problems solved by technology

This method has two disadvantages: one is that it is impossible for GPS positioning to be successful indoors, but the GPS module is turned on within a fixed time (such as 1 minute), which wastes power consumption for GPS positioning; In some places, it may take more than the above fixed opening time (such as 1 and a half minutes) to successfully locate, but at this time the GPS module has been turned off, and GPS positioning cannot be performed

Embodiment 1

[0027] see figure 1 , figure 1 It is a schematic flowchart of a method for saving power consumption of GPS positioning disclosed by an embodiment of the present invention. like figure 1 As shown, the method may include the following steps.

[0028] 101. After the GPS module is turned on, the wearable device uses the prediction model every first specified time to predict whether the GPS positioning is successful within the second specified time; where the second specified time is longer than the first specified time, the prediction The model at least includes the collected time T required for the final successful GPS positioning under the number s1 of historically connected satellites and the average signal strength c1 of historically connected satellites.

[0029] In the embodiment of the present invention, wearable devices may include various smart wearable devices such as smart watches (such as phone watches), smart bracelets, smart ankle rings, smart earrings, smart neck...

Embodiment 2

[0047] see figure 2 , figure 2 It is a schematic flowchart of another method for saving power consumption of GPS positioning disclosed by an embodiment of the present invention. exist figure 2 In the described method, it is assumed that both the wearable device and the mobile device are located in a building (such as a shopping mall), and the wearable device is not close to the entrance of the building, the mobile device is close to the entrance of the building, and the mobile device uses inertial measurement unit to locate the location information of the mobile device. For example, see image 3 , image 3 It is a plane example diagram of an indoor environment of a building disclosed in an embodiment of the present invention. like image 3 As shown, the entrance of the building can be a building gate (indicated by a black thick line), the wearable device is not close to the entrance of the building, and the mobile device is close to the entrance of the building (the s...

Embodiment 3

[0074] see Figure 4 , Figure 4 It is a schematic flowchart of another method for saving power consumption of GPS positioning disclosed by an embodiment of the present invention. exist Figure 4 In the described method, as image 3 As shown, assume that both the wearable device and the mobile device are located in a building (such as a shopping mall), and the wearable device is not close to the entrance of the building, the mobile device is close to the entrance of the building, and the mobile device uses the inertial measurement unit to locate The location information of the mobile device. like Figure 4 As shown, the method may include the following steps:

[0075] 401. Before the GPS module is turned on, the wearable device acquires a positioning request sent by a user device through a service device.

[0076] Optionally, attribute information may be carried in the positioning request, and the attribute information may include not only the identity of the wearable de...

Abstract

A method for saving power consumption of GPS positioning and a wearable device, the method comprising: after the GPS module of the wearable device is turned on, using a prediction model every first specified time to predict whether this time the GPS module can be used within the second specified time. The positioning is successful; wherein, the second specified duration is longer than the first specified duration, and the prediction model includes at least the collected time T for successful final GPS positioning under the historical connection satellite number s and the historical connection satellite average signal strength c; if it is predicted that this time If the GPS positioning fails within the second specified time period, the GPS module is turned off. Implementing the embodiment of the present invention can save power consumption of GPS positioning of the wearable device.

Description

technical field [0001] The invention relates to the technical field of wearable devices, in particular to a method for saving power consumption of GPS positioning and a wearable device. Background technique [0002] At present, many children's phones and watches on the market use GPS modules for GPS positioning, so that parents can obtain the location of their children in time. Because the battery capacity of children's phones and watches is generally small, and the GPS positioning power consumption of the GPS module is high, it is generally not possible to turn on the GPS module for a long time. In practical applications, usually when the parents want to obtain the location of the child, after the server sends a positioning command to the child's phone watch, the child's phone watch turns on the GPS module for GPS positioning. [0003] However, since it is not known how long it takes for the GPS module of the children's phone watch to be successfully positioned, the genera...
