Embodiment Construction

[0039] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0040] Based on the problem that real-time positioning cannot be realized in the WLAN positioning process in the related art, or the positioning process is complicated and the environment is limited, an embodiment of the present invention provides a mobile terminal. The structure of the mobile terminal is shown as follows figure 1 shown, including:

[0041] The first antenna 1 is configured to transmit a first signal to the anchor node, where the first signal is used by the anchor node to detect the signal strength of the first antenna 1;

[0042] The second antenna 2 is arranged at a predetermined angle with the first antenna 1, and is used to transmit a second signal to the anchor node, wherein th...

Abstract

Disclosed are a mobile terminal and a locating method and device. The mobile terminal comprises: a first antenna set to transmit a first signal to an anchor node, the first signal being used by the anchor node to detect the signal strength of the first antenna; and a second antenna arranged with the first antenna in accordance with a preset angle and set to transmit a second signal to the anchor node, the second signal being used by the anchor node to detect the signal strength of the second antenna, the preset angle enabling the coverage ranges of the first antenna and the second antenna to be overlapped, and the signal strength of the first antenna and the signal strength of the second antenna being used for determining the location of the mobile terminal. The present invention is applied to solve the problem that in a WLAN locating process, real-time locating cannot be achieved, or the locating process is complex, and the environment is restricted in the related art, thereby being able to achieve flexible real-time locating through a mobile terminal with two antennas without environmental restriction and with more accurate locating accuracy.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a mobile terminal, a method and device for determining an angle between a mobile terminal and an anchor node, and a positioning method and device. Background technique [0002] The positioning system based on Wireless Local Area Network (WLAN) has the advantages of low cost, high precision, and wide application range (indoor and outdoor), and has achieved great success in location-based services such as emergency rescue, intelligent transportation, and indoor positioning and navigation. with great success. However, there are still two problems that need to be solved urgently: (1) The fluctuation of Received Signal Strength (RSS) caused by factors such as multipath interference seriously deteriorates the positioning accuracy of WLAN; Point, referred to as AP for short) does not cover the area, because the lack of AP leads to WLAN positioning failure. [0003] In order to solve...
