Embodiment Construction
[0047] The present invention provides an auxiliary positioning method and system based on WiFiAware. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0048] see figure 1 , figure 1 It is a flow chart of a preferred embodiment of the WiFiAware-based assisted positioning method of the present invention, as shown in the figure, which includes steps:
[0049] S1. The current smart terminal receives a user instruction to enable WiFiAware, and establishes a connection with other smart terminals around which WiFiAware is turned on;
[0050] S2. Obtain the latitude and longitude information of other smart terminals, and calculate the relative distance between the current smart terminal and other smart terminals...

The invention discloses an auxiliary positioning method and system based on WiFiAware. The method includes the steps that firstly, a current intelligent terminal receives a user instruction to start WiFiAware and establishes connection with peripheral other intelligent terminals starting WiFiAware; then longitude and latitude information of the other intelligent terminals is acquired, and the relative distances between the current intelligent terminal and the other intelligent terminals is calculated; finally, longitude and latitude information of the current intelligent terminal is calculated according to the longitude and latitude information of the other intelligent terminals and the relative distances between the current intelligent terminal and the other intelligent terminals. Under the condition that the current intelligent terminal has no network signals or satellite signals, accurate positioning information of the current intelligent terminal is acquired through WiFiAware, effective navigation information is further obtained conveniently, and the requirements of users are met.
Description
technical field [0001] The invention relates to the field of intelligent positioning, in particular to a WiFiAware-based auxiliary positioning method and system. Background technique [0002] With the development of smart terminal technology, its functions are continuously enriched, which brings a lot of convenience to the life of users, especially the navigation function. Users can quickly find the target location in an unfamiliar environment by turning on the navigation function, which is not only convenient and fast, but also has high accuracy. However, in the navigation service of the existing intelligent terminal, either network positioning or satellite positioning is adopted, which requires the user to ensure that the network is smooth and the satellite positioning function is available when using the corresponding function. However, in the process of practical application, the network signal is often poor and the satellite positioning function is unavailable due to r...
