Method and system for positioning IoT cloud correction wearable device under high-speed movement

Abstract

The invention provides a method for positioning an IoT cloud correction wearable device under high-speed movement, which comprises the following steps that: an intelligent positioning system establishes a position positioning information queue for the wearable device, and the wearable device periodically acquires self position positioning information and uploads the self position positioning information to a cloud server, the cloud server analyzes the received position positioning information, calculates whether the wearable device is in a high-speed moving process or not, calculates whether missing positioning information exists or not, and inserts the missing positioning information into a position positioning information queue. According to the invention, the intelligent positioning system establishes a positioning information queue for the wearable device, automatically calculates the continuous moving speed of the wearable device, identifies whether the wearable device and a wearer thereof are in a high-speed moving process, and automatically corrects the position positioning information of the wearable device, thereby greatly improving the user experience.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to a method and system for IoT cloud correction and positioning of wearable devices under high-speed movement. Background technique [0002] With the improvement of social informatization, more and more wearable devices are used in people's daily life, and are used in people's safety, health, travel and other aspects. Many applications of wearable devices work based on location information and need to rely on the location of the device. However, wearable devices need to work in the energy-saving mode, and cannot continuously perform positioning, but periodically perform position positioning every few minutes, making the positioning time of the GPS long, coupled with signal occlusion, interference, equipment Due to reasons such as moving too fast, it is prone to inaccurate positioning, position deviation, or even positioning failure without position informatio...

However, wearable devices need to work in the energy-saving mode, and cannot continuously perform positioning, but periodically perform position positioning every few minutes, making the positioning time of the GPS long, coupled with signal occlusion, interference, equipment Due to reasons such as moving too fast, it is prone to inaccurate positioning, position deviation, or even positioning failure without position information.

Especially in scenarios such as high-speed railways and highways, especially in long-distance tunnels, GPS positioning fails and even mobile communication network information cannot be obtained, resulting in no location information at certain periods of time or the distance between the location information and the previous location is too large However, if it is discarded by mistake, it will seriously affect the wearer's application experience.
