Abstract

The invention discloses a positioning method of wireless signal transmission parameter determination based on area division, wherein the method comprises the following steps: arranging a plurality of known position nodes according to a practical condition, obtaining coordinates of the known position nodes by virtue of a gateway, building a network map in a monitoring centre, and dividing positioning minimal area; determining a wireless signal attenuation model of reference points according to a logarithmic distance loss model; respectively calculating initial parameters on the connection line between each known position node and adjacent known position node according to the wireless signal attenuation model; weighting or correcting the initial parameters in different areas according to the signal intensity of communication among the position node to be measured and the known position nodes, so as to obtain the distance from the position node to be measured and the known position node within the communication range; and obtaining the coordinates of the position node to be measured according to the coordinates of the distance from the position node to be measured and the known position node within the communication range and the known position node within the communication range.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a positioning method for determining wireless signal transmission parameters based on area division. Background technique [0002] Commonly used position measurement methods for wireless positioning include: positioning based on time of arrival (TOA), positioning based on time difference of arrival (TDOA), positioning based on angle of arrival (AOA), and positioning based on received signal strength. Indicates RSSI (Received Signal Strength Indicator) positioning, connectivity-based positioning, hop-based positioning, etc. Among them, the location measurement methods based on TOA, TDOA, and AOA have higher positioning accuracy, but also have high requirements for hardware and power consumption, and are not suitable for large-scale wireless positioning networks; Although the location measurement method of the method has low precision, it has the advantages of not req...
