the system is realized by a positioning method which comprises the steps of obtaining label information of RFID labels scanned by each wireless routing node in a wireless routing node sub-module;
identifying the personnel or articles to be positioned corresponding to the RFID labels according to the label information, and determining the positions and the motion tracks of the RFID labels according to the signal attenuation values of the RFID labels scanned by each wireless routing node submodule;
identifying the person or article to be positioned corresponding to the RFID label according to the label information to obtain video information of the person or article to be positioned, and determining the motion track of the person or article to be positioned according to the video information obtained by each video wireless routing node submodule;
equally dividing a two-point positioning area into a plurality of sub-areas on the three-dimensional map, wherein the sub-areas are equal in area; respectively taking the coordinates of the central point of each sub-region as the identification points of each sub-region;
recording the linear distance between each sub-area mark point and two wireless routing nodes closest to the sub-area, and calculating a first ratio of the two linear distances; calculating the ratio according to the setting position of the wireless routing node and calculating in sequence according to a fixed sequence;
taking the first ratio and the serial numbers of the two wireless routing nodes participating in calculation as the IDs of the corresponding sub-areas; when a certain RFID label enters an area to be monitored, acquiring serial numbers and signal strengths of two wireless routing nodes with the strongest signals, and calculating a second ratio of the signal strengths of the two wireless routing nodes according to the fixed sequence; searching a corresponding sub-area group according to the serial numbers of the two wireless routing nodes; and comparing the second ratio of the signal intensity with a preset ratio corresponding to each sub-region in the sub-region group, selecting the sub-region with the minimum difference as a target sub-region, and taking the central point of the target sub-region as the current position of the indoor RFID label.
