Embodiment Construction

[0027] In order to further understand the features of the present invention, please refer to the following detailed description and accompanying drawings of the present invention. However, the accompanying drawings are provided for reference and illustration only, and are not intended to limit the protection scope of the present invention.

[0028] Such as figure 1 Shown is a schematic diagram of an existing RFID radio frequency identification system. Paste or insert one or more electronic tags 101 on one or more goods or other objects to be tracked, and workers hold the RFID card reader terminal 102 to read the data on the electronic tags 101 through radio frequency, and then transmit the data to the management computer 103 for subsequent management such as statistics and analysis. Therefore, enterprise managers can know the production dynamics in time through the management computer 103, and conveniently track products whose quality does not meet the requirements, thereby h...

Abstract

The invention discloses a radio frequency identification device having bidirectional data transmission and statistic, comprising a radio frequency card reading terminal, a supervisory computer, a radio server and an interface conversion device. The radio frequency card reading terminal comprises a central processing unit, a first radio receiving and sending unit and a liquid crystal display; the radio server comprises a second radio receiving and sending unit and a communication interface, wherein the first radio receiving and sending unit is connected with the second radio receiving and sending unit without wires to receive and send data; the radio server is connected with the supervisory computer by the way that the communication interface is connected with the interface conversion device to receive and send data; the central processing unit stores and analyzes data read by the radio frequency card reading terminal and displays the data on the liquid crystal display.

Description

Technical field [0001] The invention relates to a data reading and writing device, in particular to a data reading and writing device based on radio frequency identification technology. Background technique [0002] Radio Frequency Identification (Radio Frequency Identification, referred to as RFID, commonly known as electronic tags) technology is a non-contact automatic identification technology, suitable for logistics management, medical industry, tracking management and monitoring of goods and dangerous goods, civil aviation luggage, Parcel management, mandatory inspection of products, certificate anti-counterfeiting, road and bridge non-stop tolls, electronic small payment tickets and other aspects of work and life; in addition, new applications are constantly being developed in the tracking of car anti-theft items. [0003] In many enterprises, especially labor-intensive, production-oriented enterprises and enterprises with complex technological processes, such as: clot...
