Problems solved by technology

[0003] The working status of the aforementioned existing radio frequency identification readers is almost manually monitored. When the staff detects a failure, they manually switch over and other processing, that is, they lack the ability to automatically switch over failures. Meet the requirements of continuity and reliability, and the reader described in this patent is developed based on this background to solve the above problems

Abstract

This invention relates to one radio identification technique reader and relates to fault switch function RFID reader and its switch method, wherein, the reader comprises power, communication interface, CPU, RF module, antenna, memory and heart beam line, wherein, the power is for RF module and CPU; the antenna and label process energy and information deliver to send the label information into CPU process and memory; through jump line sends jump information between main and aid reader; then by use of fault switch module to control whether the reader is in charge of main reader work; aid reader automatically takes charge of main reader work in fault.

Description

technical field [0001] The invention relates to the technical field of readers based on radio frequency identification technology, in particular to an RFID reader with a failover function and a failover method thereof. Background technique [0002] RFID (Radio Frequency Identification, radio frequency identification) technology is an automatic identification technology that began to emerge in the 1990s. It uses radio frequency signals to achieve non-contact information transmission through spatial coupling (alternating magnetic field or electromagnetic field). The technology that the transmitted information achieves the purpose of automatic identification. Due to the advantages of non-visual transmission, fast transmission speed, strong penetrability, strong resistance to harsh environments and reusability, this technology has attracted the attention of many industries and professionals. Looking at domestic and foreign RFID systems, its basic components are radio frequency ...
