Abstract

The invention discloses a method for locating relative positions of RFID tags based on deep learning. The method includes steps: S1. Arrange a series of RFID tags uniformly and horizontally in a random order, keep an RFID antenna parallel to the movement of the RFID tags, and use the The RFID antenna continuously reads the phase information data and the signal strength information data between the RFID tags; S2, setting a data arrangement structure, based on the data arrangement structure, the phase information data and the signal strength information data are prepared into training data, and adopt the deep neural network to train the training data, and initially obtain the relative positional relationship between all the RFID tags; The relationship is further sorted to determine the final relative positional relationship between all the RFID tags; the method of the present invention can accurately analyze the sequence of a series of densely arranged RFID tags.

Description

technical field [0001] The invention belongs to the technical field of machine learning and the Internet of Things, and in particular relates to a mutual positioning technology of RFID (Radio Frequency Identification, radio frequency identification), especially a method for relative position positioning of RFID tags based on deep learning. Background technique [0002] Most of the current positioning research is still aimed at the absolute position. However, in many situations, the relative position of the object is more important than its absolute position. For example, in the library, librarians find misplaced books or For archives, we need to obtain the current order of books on the bookshelf rather than their absolute coordinate values; on the conveyor belt, we only need to know the relative relationship between the front and back of the object, and do not need to know the absolute coordinate value of the object. The same is true for the sorting of items in some warehous...
