Abstract

The invention discloses a bluetooth indoor micro-positioning system based on an ELMAN neural network. The system comprises a system host, a bluetooth anchoring point and a positioning target, the system host comprises an embedded processor, a bluetooth main node and a communication module, the bluetooth main node (main node bluetooth module) adopts a low-power-consumption bluetooth wireless data transmission module RL-CC2541-S3, a SIM900A is used for communication with a host computer, a CC2541 acquires a host signal intensity indication required by positioning, one bluetooth module is fixed on the positioning target, the system host and the bluetooth anchoring point are arranged in a positioned indoor area, the bluetooth module fixed on the positioning target operates in a host mode, andthe bluetooth main node and the bluetooth anchoring point operate in a slave mode. According to the system, the precision and the stability of the positioning technology are improved, certain adaptability to the environment is achieved, and technical support is provided for implementation of a complex positioning algorithm.

Description

technical field [0001] The invention relates to an information system, in particular to a bluetooth indoor micro-positioning system based on an ELMAN neural network. Background technique [0002] On the basis of the existing Bluetooth-based indoor positioning, the present invention uses the Elman neural network algorithm, which greatly improves its stability and precision. In the placement of Bluetooth, the change of position is basically not due to errors. And in the system host module, the upper computer can be linked, data can be directly transmitted, and more complex positioning calculation can be performed, which enhances the applicability of the method. The method of indoor positioning technology has gradually matured, but the accuracy and stability of indoor positioning based on Bluetooth will be affected differently in different indoor environments. The present invention is aimed at this situation, makes up for the accuracy and stability of the Bluetooth indoor pos...
