Embodiment Construction
[0070] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0071] An improved multi-area adaptive indoor positioning method based on RSSI ranging of the present invention, the flow chart is as follows figure 2 shown, follow the steps below:
[0072] Step 1: Divide the target area into multiple sub-area environments according to the indoor structural characteristics, and build a Shadowing extension model based on the environment parameter library, which is implemented according to the following steps:
[0073] Step (1.1), the positioning coverage area is divided according to the target area structure to form n sub-regions, and the positioning coverage area is represented by A, then A={a 1 , a 2 , a 3 , β¦, a n};
[0074] Step (1.2), set each sub-region a i In the same environment, where i=1, 2, ..., n, according to the Shadowing model, each a i Path loss exponent n corresponding to other regions ...
