Embodiment

[0038] This embodiment includes the following steps:

[0039] Step 1, such as figure 1 As shown, a reference node is set, and a two-dimensional coordinate system with the reference node as the origin is established. The two-dimensional coordinate system includes a horizontal axis and a vertical axis; the node to be measured falls on the plane of the two-dimensional coordinate system, The angle between the connection line between the node to be tested and the reference node and the horizontal axis is the positioning angle, and the distance between the node to be tested and the reference node is the positioning distance;

[0040] Step 2. Place a rotating antenna on the reference node. During the rotation of the rotating antenna, the angle corresponding to the maximum signal strength received by the node under test is the positioning angle; by measuring the signal strength transmitted by the reference node and the receiving node under test Calculate the attenuated signal strength bas...

Abstract

An indoor positioning method on the basis of a rotary antenna relates to a mobile terminal indoor positioning technology, and comprises that step 1, a reference node and a node to be tested are set, a two-dimensional coordinate system which takes the reference node as an origin is built, and comprises a horizontal axis and a longitudinal axis, the node to be tested is required to be located in the plane of the two-dimensional coordinate system, the included angle between a connecting line of the reference node and the node to be tested and the horizontal axis is a positioning angle, and the distance between the reference node and the node to be tested is a positioning distance; step 2, the positioning angle and the positioning distance are measured; and step 3, through an algorithm of a distance and an energy relational model, and the positioning angle, the two-dimensional coordinates of the node to be tested on the plane of the two-dimensional coordinate are calculated, so the node to be tested is positioned. The method has the advantages of avoiding error superposition, realizing point positioning, high precision and the like.

Description

Technical field [0001] The present invention relates to an indoor positioning technology of a mobile terminal, in particular to an indoor positioning method based on a rotating antenna. Background technique [0002] With the optimization of the network environment and the popularization of mobile terminals, with the rapid development of high-speed wireless communications and advanced network technologies, positioning technology has gradually entered people's daily lives, and its applications have become more and more common. Positioning is to determine the location to be measured based on the geographic information of a few known locations of nodes through a certain algorithm analysis. Among them, the Global Positioning System (GPS) has been widely used in the world, and its development speed and popularity have been confirmed. Positioning technology has brought great convenience to human life. [0003] Wireless network acquisition and bandwidth requirements are no longer the bigg...
