Adaptive multi-communication-protocol ultrahigh-frequency RF identification reader-and-writer

Abstract

The invention provides an adaptive multi-communication-protocol ultrahigh-frequency RF identification reader-and-writer which comprises the components of a control module, a transmitting module, a directional coupling module, an antenna module, a receiving module, an adaptive multi-communication-protocol interface conversion module and a power supply module, wherein the adaptive multi-communication-protocol interface conversion module is composed communication protocol interfaces such as RS232 / RS485 / USB / RJ45 / WiFi / TTL and a group of digital switches. The control module performs adaptive determination for a communication interface protocol in connection and makes a digital switch be automatically switched to a corresponding communication protocol interface. The adaptive multi-communication-protocol ultrahigh-frequency RF identification reader-and-writer can be adapted with multiple current universal communication protocols and facilitates modular application in various different environments. Furthermore flexible system establishment is realized.

Description

technical field [0001] The invention relates to the field of radio frequency technology, in particular to an ultra-high frequency radio frequency identification reader-writer with adaptive multi-communication protocols. Background technique [0002] Radio Frequency Identification (RFID) is a wireless communication technology, which is a non-contact automatic identification technology that uses radio frequency signal space coupling to identify targets and obtain target data. The most important advantage of RFID technology is non-contact identification, and it can read labels through harsh environments such as snow, fog, ice, paint, dust and other barcodes that cannot be used, and can also identify multiple labels at the same time. It has the advantages of diversification, strong anti-pollution ability, reusability, large memory capacity of data and encryption. With the development of RFID technology, its application fields are becoming more and more extensive, such as food s...
