Intelligent reading and writing device and method for RFID (Radio Frequency Identification)

Abstract

The invention discloses an intelligent reading and writing device and method for RFID (Radio Frequency Identification). Simultaneous reading and writing for low-frequency, high-frequency and ultrahigh-frequency RFID tags are achieved through using the intelligent reading and writing device for RFID and the method applied to the device. In addition, the simultaneous reading and writing range can beadjusted according to actual requirements. Furthermore, the intelligent reading and writing device is provided with a communication module, thereby enabling multiple devices to operate in a networking manner. The intelligent reading and writing device can also be combined with a status indicator lamp of production and manufacturing equipment, thereby reducing the purchasing cost, achieving the coordination, concentration and stability of work and reducing the maintenance cost.

Description

technical field [0001] The invention relates to the field of radio frequency identification, in particular to a device and method for intelligent reading and writing of RFID. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] RFID is a wireless communication technology, also known as radio frequency identification, which can identify specific targets and read and write related data through radio signals without establishing mechanical or optical contact between the identification system and specific targets; radio signals are tuned into radio frequency An electromagnetic field that transmits data from a tag attached to an item for automatic identification and tracking of the item. Some tags can get energy from the electromagnetic field emitted by the identifier when they are identified, and do not need a battery;...

Problems solved by technology

[0004] In today's era of the Internet and the Internet of Things, it has promoted the upgrading and transformation of related sensing and reading and writing technologies, and the application of RFID tags has been widely used. At the same time, a large number of RFID reading and writing equipment and supporting equipment have emerged. ;At present, the RFID reading and writing equipment on the market only reads and writes a certain type of tag, and cannot read and write low-frequency, high-frequency and ultra-high-frequency RFID tags at the same time. Adjustment, the equipment cannot be connected with the enterprise MES / ERP system for data transmission, and multiple equipment cannot be networked and can only operate alone, and cannot communicate with other equipment, such as electronic scales and sensors; nor can it communicate with the status of manufacturing equipment The combination of indicator lights will easily increase the cost of equipment procurement, and there is no work coordination, and the equipment is scattered and cannot be controlled centrally, which increases the hidden dangers and instability of work, resulting in an increase in maintenance costs.
