Problems solved by technology

[0003] Among them, RFID tags can be divided into two types: active (Active) and passive (Passive). Active tags contain batteries, which can transmit information to the reader at any time, and have a longer communication distance and can store larger memory, but the price is higher; passive tag power comes from the radio wave sent by the reader to induce a micro current to the tag to supply its power, and then use the radio wave to transmit its information back to the reader, so the communication distance is short

Abstract

The invention discloses portable electronic equipment and a mobile RFID reader, wherein the mobile RFID reader can be moved to a required position by a user, senses RFID tag information of a subject matter and is composed of a microprocessor, a connecting memory unit, a reader locating unit, a radio frequency transceiving module, an information buffer unit and a network interface. The reader locating unit is used for locating self position of the RFID reader, and the radio frequency transceiving module is used for receiving tag signals transmitted by an RFID tag. When in an off-line state, reader position data and tag identification data of the RFID tag are temporally stored in the information buffer unit, and then uploaded to a rear-end network server after the rear-end network server isin an on-line state.

Description

technical field [0001] The present invention relates to the design of a radio frequency identification reader, in particular to a mobile radio frequency identification reader which indirectly locates a radio frequency identification tag by locating its own location. Background technique [0002] A known radio frequency identification (RFID) system mainly includes a radio frequency identification tag (RFIDTag), a radio frequency identification reader (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 reader 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 tag 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 divided into two ...
