Abstract

An operation method of a radio frequency identification reader is disclosed. The reader comprises a processor, a storage module and a Bluetooth module, wherein the Bluetooth module is used for continuously receiving a plurality of data packets transmitted by other readers, and each data packet comprises a priority value and a state of the corresponding reader. Therefore, the reader can judge whether the label can be read or not according to a plurality of received data packets so as to avoid collision of the reader.

Description

technical field [0001] The invention relates to an operation method of a radio frequency identification reader, in particular to an operation method capable of avoiding the collision of the radio frequency identification reader. Background technique [0002] Radio Frequency Identification (RFID) is a wireless communication technology that uses radio waves to transmit information and is widely used in different industries. Although radio frequency identification brings a lot of convenience, there are also many restrictions on its use. For example, in the management environment of warehouses or airports, multiple readers are arranged in one space. At this time, it is easy for two The above readers are within the reading range of each other resulting in a situation where the reading ranges overlap, which is called a dense reader environment. In an environment with dense readers, it is easy to cause the same tag to be read by multiple readers at the same time, that is, reader c...
