Problems solved by technology

[0002] The current mobile GPS devices (GPS bracelets, children's watches, sports watches, mobile phones, etc.), the GPS of these mobile devices consumes a lot of power when they work continuously, but the battery capacity of mobile devices is limited, which cannot meet the long-term requirements. Endurance requirements
[0003] GPS consumes a lot of power when it works, because APs are required to participate in algorithm decoding. The current mainstream GPS solution for mobile phones is that the GPS chip (GPS logic controller) receives satellite information from the sky, and then transparently transmits the original satellite information to the AP, and the AP passes the corresponding algorithm Analyze GPS information such as latitude and longitude. For the analysis of location information, the AP CPU has a very large amount of calculation, resulting in high power consumption, which can generally reach 150mA to 200mA

Embodiment 1

[0032] A method for reducing the power consumption of GPS operation of a device, comprising the following steps: obtaining G-Sensor data of the device through a sensor embedded in the device, processing the corresponding G-Sensor data to determine the state of the current device; if the current device is in a motion state, then Corresponds to enable the GPS function; if the current device is in a static state, it corresponds to disable the GPS function.

[0033] The above-mentioned G-Sensor data includes X / Y / Z three-axis vector data, and processes the X / Y / Z three-axis vector data at the same time, and judges whether the current device is in a motion state or a static state according to the processing results.

[0034] Among them, set the X-axis vector data to X, the Y-axis vector data to Y, and the Z-axis vector data to Z, then get The result data, specifically the result data is the value of the sum of the square of X + the square of Y + the square of Z, and the square root ...

Embodiment 2

[0040] refer to figure 1 As shown, this embodiment provides specific working scenarios and workflows:

[0041] In this embodiment, the embedded M3 low-power processor is used to process the corresponding G-Sensor data, which is integrated into the dynamic and static algorithm.

[0042] Increase dynamic and static message receiver at A core driver layer, increase dynamic and static message distributor at A nuclear upper layer control layer; Described A core is AP (processor of baseband chip), i.e. the CPU of soc,

[0043] A method for reducing device GPS operating power consumption, comprising the following steps:

[0044] Step 1. The M3 low-power processor judges the motion state of the mobile phone through the dynamic and static algorithm. The dynamic and static algorithm can judge the motion state of the terminal through the G-Sensor data and report it to the A core. The algorithm for judging the motion state of the terminal through the G-Sensor is currently Mature algorit...

Embodiment 3

[0049]In addition to the method adopted in Embodiment 1 and Embodiment 2, this embodiment provides a device for reducing the power consumption of the GPS device, including: an M3 low-power processor integrated into the dynamic and static algorithm; connected with a dynamic and static message receiver And the processor of the baseband chip of the dynamic message distributor; and the GPS logic controller controlling the opening and closing of the GPS function.

[0050] In summary, the present invention recognizes the motion state of the mobile device through the G-Sensor of the mobile device. When the mobile device is in motion, the GPS logic controller is turned on; when the mobile device is in a static state, the GPS logic controller is turned off, so that The AP sleeps to reduce the average power consumption.

[0051] For the software upgrade in the present invention, the function of the present invention can be realized as long as the following three hardware conditions are ...

Abstract

The invention discloses a method and a device for reducing the running power consumption of a GPS of equipment. The method comprises the following steps that G-sensor data of the equipment are acquired through a sensor embedded in the equipment, and the corresponding G-sensor data are processed to judge the state of a current device; if the current device is in the motion state, the GPS function is started correspondingly; and if the current equipment is in a static state, the GPS function is closed correspondingly. According to the method, on the premise that any hardware cost is not increased, the power consumption of severe users of the GPS is reduced only through a software upgrading mode, and the endurance time is prolonged.
