Embodiment Construction

[0043] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0044] The flow of the first embodiment of the passive coarse-grained label location positioning method of the present invention is as follows figure 1 Shown:

[0045] Step 101: Analyze the sequence of the reading rate, find out the region where the tag attached to each object maintains stability in the reading range of the tag reader as the key region.

[0046]The key area finding algorithm runs on the tag reader agent, statistics and analyzes the reading rate sequence of the tag on each object, and provides input for finding the maximum signal strength point in the key area in the second stage.

[0047] The main operation of the key area finding algorithm is to analyze the reading rate of each object in unit time, and quickly determine the key area of ​​the object. However, due to the different ...

Abstract

The invention provides an implementation method and a system for coarse granularity locating of passive label location. The method includes the steps: analyzing sequence of a read rate, finding out an area where a label, attached to each object, maintains stable in a reading range of a label reader as a key area; obtaining a time point when a maximum value of signal strength of each object appears in the key area; comparing the time points when the maximum values of the signal strength of the objects appear, and obtaining a precedence location relationship of the objects. By adoption of the implementation method and the system for the coarse granularity locating of the passive label location, the purpose of the sequence of the objects in a moving condition can be achieved.

Description

technical field [0001] The invention belongs to the field of wireless ad hoc networks and mobile radio frequency tag systems, and in particular relates to a method and system for realizing passive coarse-grained positioning of tag positions. Background technique [0002] With the maturity of communication technology and embedded devices, Radio Frequency Identification (RFID) technology develops rapidly and is widely used in many fields such as supply chain management, warehouse management, and logistics. A typical mobile RFID tag system consists of a conveyor belt, a tag reader, and a large number of tags. The tag reader is set up on the conveyor belt, and when the goods enter the reading range of the tag reader, the stored information will be sent to the tag reader through backscatter communication. Here each tag stores information about the goods it corresponds to and is therefore unique. [0003] At present, a lot of research work has been devoted to how to apply the mo...
