Problems solved by technology

[0003] Among them, RFID tags can be divided into two types: Active and Passive. Active RFID tags contain batteries, which can transmit information to RFID reading devices at any time, and have a longer communication time. Distance, can store larger memory, but the price is higher; the power of passive RFID tags comes from the radio waves sent by the reading device to induce micro-currents to the RFID tags to supply its power, and then use the radio waves to transmit its information back Radio frequency identification reading device, so the communication distance is short

Abstract

The invention relates to an identifying and positioning method of radio frequency identification reading devices. The method comprises the following steps: a first radio frequency identification reading device transfers identifying and positioning data to main control equipment to identify through a data transmission interface; the first radio frequency identification reading device transfers theidentifying and positioning data through a radio frequency identification receiving and sending module of the first radio frequency identification reading device; and a second radio frequency identification reading device which is adjacent to the first radio frequency identification reading device transfers the identifying and positioning data to the main control equipment to identify through thedata transmission interface after the second radio frequency identification reading device receives the identifying and positioning data transferred by the first radio frequency identification readingdevice.

Description

technical field [0001] The present invention relates to an identification technology using a radio frequency identification system, in particular to an identification and positioning method and a reading device for a radio frequency identification reading device. Background technique [0002] A known radio frequency identification (RFID) system mainly includes a radio frequency identification tag (RFIDTag), a radio frequency identification reading device (RFID Reader), and at least one backend computer host. Among them, the radio frequency identification tag is a data storage component, and the radio frequency identification reading device is a tool for reading data from the radio frequency identification tag or storing the data in the radio frequency identification tag, and receiving the wireless signal of the radio frequency identification tag After that, the read data is sent to the back-end computer host for various data processing. [0003] Among them, RFID tags can be...
