Embodiment Construction

[0015] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, in the framework and method of the RFID intelligent supervision shelf system, the entire shelf is arranged in layers, and object tags are placed on each layer, and the reader is placed in the middle of the shelf to obtain the maximum sensing range. According to the position of the RFID reader is set as the origin, a 3-dimensional Cartesian coordinate system is established, the X axis is parallel to the shelf surface, the Y axis is perpendicular to the shelf surface, and the vertical direction is the Z axis. The placement of objects on each layer is on the same X-Y plane. Assuming that the position of each tag is a fixed point, the purpose is to sense the position of each fixed point through RFID, and further complete the matching of the fixed point on the shelf with the object placed at its position.

Abstract

The invention relates to a UHF RFID intelligent supervision shelf system architecture and method, which is characterized in that the system architecture and method take the placement and constructionof a common shelf as a design principle, and for the first time, the UHF RFID technology is utilized to carry out shelf supervision and management through a standardized shelf adjustment mode. A set of intelligent shelf monitoring method with high reliability and high accuracy is innovatively created to achieve a set of adjustment and deployment strategy based on the system. In the architecture ofthe system, the shelves are labeled with fixed point locations, a single reader is deployed in front of the smart shelves, and the deployment distance is controlled so that the entire reader covers the entire shelf. The system realizes the one-to-one correspondence between the theoretical value and the actual value by using the phase matching, and then realizes the deployment and reliability calculation of each shelf level by using the reliability theory, and divides the layers by using the RSSI, so as to realize the reliability deployment and real-time monitoring service of the intelligent shelf.

Description

technical field [0001] The invention relates to an ultra-RFID intelligent supervision shelf system architecture and method. Aiming at the placement and construction of ordinary shelves as the design principle, it is first proposed to use ultra-high frequency RFID technology to supervise and manage shelves through the adjustment of standardized shelves. Innovatively designed a set of highly reliable and accurate intelligent shelf supervision methods, and realized a set of adjustment and deployment strategies based on this system. Deploy a single reader in front of the shelf, and control the deployment distance so that the entire reader covers the entire shelf, use phase matching to achieve one-to-one correspondence between theoretical values ​​and actual values, and then realize the deployment and reliability of each layer on the shelf through reliability theory Calculate, use RSSI to divide between layers, so as to realize the reliable deployment and real-time supervision serv...
