Method for reducing positioning power consumption of wearable equipment and guaranteeing positioning precision

Abstract

The embodiment of the invention discloses a method for reducing the positioning power consumption of wearable equipment and guaranteeing the positioning precision. The method comprises the following steps that position information is acquired by the wearable equipment; the wearable equipment sends the acquired position information to a center calculation server and carries out zero clearing on historical displacement; the wearable equipment acquires relevant data through a sensing device, and displacement data of the wearable equipment is calculated through the relevant data; the displacementdata calculated by the wearable equipment is compared with a preset displacement threshold, and if the displacement data exceeds the preset displacement threshold, the position information is collected again; if the displacement data does not exceed the preset displacement threshold, the wearable equipment does not need to carry out further data calculation after the center calculation server receives an event indicating that the wearable equipment is not moved, and then the position point closest to the equipment can be used.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of the Internet of Things, and in particular to a method for reducing power consumption of a wearable device to ensure positioning accuracy. Background technique [0002] As wearable devices play an increasingly important role in the intelligent connection between people and things, things and things, and people and people, the positioning of high-precision wearable devices has become an indispensable feature in these scenarios. Improving Positioning Accuracy A common practice in the industry to improve positioning accuracy is to reduce the acquisition cycle and increase the acquisition frequency. [0003] But this brings more problems: frequently enabling Bluetooth, WiFi, GPS and other chips and obtaining location-related information through them will generate more energy consumption and greatly reduce the standby time and experience of the wearable device; even if the wearable dev...

Problems solved by technology

[0004] To this end, the embodiment of the present invention provides a method for reducing the power consumption of wearable device positioning to ensure positioning accuracy, so as to solve the problem of frequently enabling Bluetooth, WiFi, GPS and other chips and obtaining positioning-related information through them in the prior art and wearable device failure. In the mobile situation, the signal strength may be different at different times. When these data are handed over to the computing center, different results may be obtained, resulting in high power consumption for collection, high computing overhead on the central computing server, and poor positioning accuracy.
