Abstract

The invention relates to a modular label positioning system and method based on the RFID technology, and the method comprises the steps: deploying an antenna array module in a specified positioning region; connecting each antenna array module to an antenna array module interface of the RFID reader-writer; positioning the object which is placed on the plane of the positioning area and is pasted with the RFID electronic tag; after the RFID reader-writer receives an object positioning command sent by the upper computer, traversing each antenna inventory label on each antenna array through each radio frequency port on the port of the antenna array module; obtaining label data of each RFID electronic label in the positioning area, the intensity of a reflection signal when the label is checked each time, the number of times that each label is checked by each antenna in unit time and other data required by object identification and positioning, and inputting the data into an upper computer; and adopting the RFID electronic tag positioning algorithm to calculating the position of the tag. According to the invention, the articles placed in the designated area can be positioned quickly and efficiently, and the positioning requirements of different industries in different scenes are met.

Description

technical field [0001] The invention relates to the field of positioning, in particular to a modular positioning method and system based on RFID technology. Background technique [0002] In recent years, with the rapid development of the Internet, the logistics, retail and other industries have advanced by leaps and bounds, followed by a huge amount of items that need to be managed. In addition, these industries may not only be satisfied with identifying these items, but often pay attention to the location of a certain item in the process of storage and sorting. The existing common solution is to identify and locate items one by one by manpower and optical-based identification methods (two-dimensional codes, barcodes, etc.). In the case of a large number of items and various types, this method is quite time-consuming and labor-intensive. [0003] According to statistics, from 2015 to 2018, the business volume of my country's express delivery companies has increased year by...
