Method, device and system for determining relative angle between intelligent devices and intelligent devices

Abstract

The invention provides a method, a device and a system for determining a relative angle between intelligent devices and the intelligent devices. The method is suitable for a first intelligent device,the first intelligent device comprises a first sound detection module and a second sound detection module, and the method comprises the following steps: enabling the first sound detection module to detect a first sound signal sent by a second intelligent device and directly reaching the first sound detection module, enabling a second sound detection module to detect a second sound signal sent by the second intelligent device and directly reaching the second sound detection module, wherein the first sound signal and the second sound signal are sent by the second intelligent device at the same time; determining the time difference between the receiving moment of the first sound signal and the receiving moment of the second sound signal; and determining the relative angle between the first intelligent device and the second intelligent device based on the distance between the first sound detection module and the second sound detection module and the time difference. The relative angle between the intelligent devices can be determined quickly, simply, conveniently and accurately.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of positioning, and more specifically, to a method, device, system, and smart device for determining a relative angle between smart devices. Background technique [0002] With the use of wireless communication technologies such as 5G, the global process of building the Internet of Things is also accelerating, and location services are the infrastructure of the Internet of Things. Location services will penetrate into many application scenarios of the Internet of Things, enabling people and objects to sense each other's location . Therefore, it is necessary to explore technologies and applications based on the mutual positioning of smart devices to realize the connection between people and people, people and things, and things and things, and improve the intelligence and humanization of work and social scenes. [0003] At present, the mutual positioning between smart devices is gene...

AI Technical Summary

Problems solved by technology

However, the positioning accuracy of the GNSS global satellite positioning system is low, and it is almost unusable especially indoors

In addition, WiFi technology and Bluetooth technology are inaccurate in judging the relative position of smart devices, and need repeated trials and comparisons with the actual distance to obtain the signal strength and environmental attenuation factor when one meter away from the Bluetooth device, so it is not reliable

At present, for the basic location service of smart devices in some small space scenarios, the existing technology is not universal
