Description

Method, Apparatus and Smart Device for Sharing File The present disclosure relates to the technical field of smart devices, in particular to a method, device, and smart device for file sharing. AirDrop allows you to wirelessly share files between multiple devices. One-to-one file transfer (similar to wireless network transfer) can be performed by simply dragging a file onto a friend's head portrait using the AirDrop feature. In conventional AirDrop, based on the spatial awareness capabilities provided by the U1 chip, a file provider connects to another file receiver, and priority is assigned according to distance (the closer the file receiver, the higher the priority), and the file is shared with the file receiver having the highest priority. However, in this implementation method, the file providing device must consciously be close to the file receiving device, so this is complex. FIG. 1 is a flowchart of a method for sharing files according to embodiments of the present disclosure. FIG. 2 is a schematic diagram of the discovery step and the ranging step in an ultra-wideband (UWB) positioning process according to embodiments of the present disclosure. FIG. 3 is a schematic diagram of a coordinate system of a UWB chip having three antennas according to embodiments of the present disclosure. FIG. 4 is a schematic diagram for determining the distance between an antenna of a UWB chip and a target device according to embodiments of the present disclosure. FIG. 5 is a schematic diagram for determining the angle between a UWB chip and a target device according to embodiments of the present disclosure. FIG. 6 is a schematic diagram for determining a target smart device from candidate smart devices according to embodiments of the present disclosure. FIG. 7 is a flowchart for determining a sharing method according to embodiments of the present disclosure. FIG. 8 is a first example of file sharing according to embodiments of the present disclosure. FIG. 9 is a second example of file sharing according to embodiments of the present disclosure. FIG. 10 is a third exemplary diagram of file sharing according to embodiments of the present disclosure. FIG. 11 is a structural diagram of a file sharing device according to embodiments of the present disclosure. FIG. 12 is a structural diagram of a smart device according to embodiments of the present disclosure. To make the purpose, technical solution, and advantages of the present application clearer, the present disclosure will be described in more detail below by exemplary embodiments with reference to the accompanying drawings. For the sake of simplicity and intuitiveness of explanation, the solution of the present disclosure will be described by explaining a few representative embodiments. Many details of the embodiments are used solely to aid in understanding the solution of the present disclosure. However, it is evident that the technical solution of the present disclosure may not be limited to these details during implementation. To avoid unnecessarily obscuring the solution of the present disclosure, some embodiments are not described in detail and only their framework is provided. Hereinafter, "comprising" means "comprising but not limited thereto," and "according to" means "at least according to, but not limited thereto." Hereinafter, where the quantity of a component is not specifically indicated due to national linguistic conventions, it means that the component may be one or many, or at least one. In an implementation of the present disclosure, ultra-wideband positioning (UWB) positioning technology is used to implement a method of sharing files based on the angle of a smart device. By utilizing said angle and other characteristics, a one-stop sharing method can be achieved by automatically connecting a target device through a predetermined decision algorithm. First, an explanation of UWB positioning technology is provided. UWB positioning technology is a positioning technology that utilizes wireless carrier communication. Since it does not use sinusoidal carriers but transmits data using nanosecond non-sinusoidal narrow pulses, it occupies a wide spectrum. UWB positioning technology possesses advantages such as low system complexity, low transmission signal power spectral density, insensitivity to channel fading, low eavesdropping capability, and high positioning accuracy, making it particularly suitable for high-speed wireless access in high-density multipath environments, such as indoors. In UWB positioning technology, time and angle information of a positioning target can be accurately obtained. By converting time information into distance information, the location information of the positioning target can be acquired by combining angle information with geometric positioning methods such as triangulation. Methods for measuring angle and time information commonly used in UWB positioning technology include Received Signal Strength (RSS)-based measurement methods
