Obviously, the described The embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a method for reducing power consumption of a wearable device provided by an embodiment of the present invention. The method can be applied to a wearable device, and the wearable device includes: a smart watch, a smart bracelet, etc. Electronic devices with positioning functions, including but not limited to wearable devices that can be applied to children, the elderly, and pets. The method includes:

S101. When the microcontroller of the wearable device acquires data, determine whether the data is preset data;

The preset data can be registered on the server and is the home hotspot information corresponding to the wearable device, or it can be information that the wearable device is in a static state and lasts for a preset duration. Such as 5 minutes.

Referring to Fig. 2, wearable device 10 comprises: wireless module 11, microcontroller (MCU, MicrocontrollerUnit) 12, baseband chip 13, satellite navigation system (GNSS, Global Navigation Satellite System) module 14 and motion sensor 15, wireless module 11 and The baseband chip 13 is respectively connected to the microcontroller 12 through a UART (Universal Asynchronous Receiver/Transmitter) serial port, and the baseband chip 13 and the satellite navigation system module 14 are connected through the UART serial port.

When it is detected that the wearable device is in a static state and the static state lasts for a preset period of time, the detected information is sent to Microcontroller12.

Specifically, the microcontroller may be a Bluetooth MCU, which communicates with the client through Bluetooth.

When the microcontroller of the wearable device acquires the data, it is judged whether the data is the aforementioned preset data.

S102. If it is preset data, then the microcontroller cuts off the power supply of the baseband chip, so that both the power supply of the baseband chip and the satellite navigation system module are cut off.

If the data is registered on the server and corresponds to the home hotspot information of the wearable device, it means that the user is using the wearable device at home;

If the data is information that the wearable device is in a static state and lasts for a preset period of time, it means that the user is wearing the wearable device but is in a sleeping or resting state, or that the wearable device is not worn by the user and placed on Tables etc. are placed on top of shelves.

In the above two cases, when the wearable device is not in use, the microcontroller cuts off the power supply of the baseband chip, and since the satellite navigation system module is connected to the baseband chip, cutting off the power supply of the baseband chip can make the baseband chip and the satellite Power to the navigation system modules has been cut.

In the embodiment of the present invention, when the microcontroller of the wearable device receives the preset data, the power supply of the baseband chip is cut off, so that the power supply of the baseband chip and the satellite navigation system module are both cut off, without affecting the user's use of the wearable device.

S202. When the microcontroller of the wearable device acquires the data, judge whether the data is registered on the server and is the information of the home hotspot corresponding to the wearable device;

S203. If it is the home hotspot information, the microcontroller cuts off the power supply of the baseband chip, so that both the power supply of the baseband chip and the satellite navigation system module are cut off.

In the embodiment of the present invention, when the microcontroller of the wearable device receives the information sent by the wireless module, registered on the server, and corresponding to the home hotspot information of the wearable device, it cuts off the power supply of the baseband chip, so that Both the baseband chip and the satellite navigation system module power supply are cut off to reduce the power consumption of the wearable device and avoid the use of large-capacity batteries without affecting the user's use of the wearable device.

Positioning cannot be achieved indoors. At this time, reducing the positioning time of the positioning system can reduce the power consumption of wearable devices.

Further, after determining whether the wearable device is located indoors, it is further determined whether the indoor is the user's home, and if so, the microcontroller cuts off the power supply of the baseband chip, so that both the power supply of the baseband chip and the satellite navigation system module are cut off; If not, the power consumption of the wearable device is reduced by adopting the above method of reducing the positioning duration.

Specifically, after determining whether the wearable device is located indoors, the microcontroller acquires the data scanned by the wireless module, and judges whether the data is the information of the registered home hotspot scanned by the wireless module, and if it is the information of the registered home hotspot, Then the microcontroller cuts off the power supply of the baseband chip, so that both the power supply of the baseband chip and the satellite navigation system module are cut off, thereby reducing the power consumption of the wearable device.

If it is not the information of the registered home hotspot, the default longest positioning duration of the first positioning is reduced to the first preset value, and the default longest positioning duration of the non-first positioning is reduced to the second preset value, the first preset The value is greater than the second preset value.

In the embodiment of the present invention, it is judged whether the wearable device is located indoors according to the number of satellites acquired and the SNR value of the satellites. If it is indoors, the default longest positioning duration of the first positioning and the default longest positioning duration of non-first positioning are reduced. , reduce the power consumption of wearable devices by reducing the positioning time, and avoid the use of large-capacity batteries.
