Embodiment Construction

[0048] As mentioned in the background, the existing positioning method has the problem of high hardware cost. For example, there is a technical solution for positioning based on WiFi in the prior art, but generally multiple hotspots need to be deployed to perform positioning, and the hardware cost is relatively high. Moreover, in some application scenarios, due to hardware cost or space constraints, it may not be possible to deploy enough hotspots, making such a positioning solution inconvenient to implement and use.

[0049] In the embodiment of the present invention, by making full use of the first antenna and the second antenna of the receiving end, the position of the receiving end relative to the hot spot is determined according to the distance from the same hot spot to the first antenna and the positioning angle, so that based on one hot spot Realize the positioning of the receiving end. Wherein, the positioning included angle is an included angle formed by a line conne...

Abstract

The invention provides a positioning method based on a single hot spot and a device based on the single hot spot. The method comprises the steps that the transmission time difference, which is between a first antenna and a second antenna, of a positioning signal which is transmitted from a hot spot to a receiving end is determined; according to the difference between the first antenna and the second antenna and the transmission time difference, a positioning angle is calculated, wherein the positioning angle is an angle formed by a line connecting the first antenna and the hot spot and a line connecting the first antenna and the second antenna; and the distance from the hot spot to the first antenna is calculated, wherein the distance from the hot spot to the first antenna and the positioning angle are used to determine the position of the receiving end. According to the scheme, hardware cost needed by positioning can be saved.

Description

technical field [0001] The present invention relates to the technical field of wireless positioning, in particular to a positioning method and device based on a single hotspot. Background technique [0002] Positioning technology is widely used, and the positioning function is the basis for realizing other intelligent interactions. For example, after the location of the terminal is determined, further navigation of the terminal can be implemented. Among the existing positioning technologies, there are positioning methods based on radio frequency identification (Radio Frequency Identification, RFID), positioning methods based on global positioning system (Global Positioning System, GPS), positioning methods based on wireless local area network (Wireless LAN, WLAN), and so on. [0003] However, the existing positioning methods have the problem of high hardware cost. Contents of the invention [0004] The technical problem solved by the present invention is to provide a pos...
