Abstract
The utility model provides an RFID reader with a function of determining a moving direction. The RFID reader comprises a first directive antenna, a second directive antenna, an information acquisition module, an information storage, a time storage, a processor, a communication module and a power supply module. Using directive antenna design, the RFID reader controls two aspects of transmitting power and directivity, accurately controls power level of transmitting signals, and controls signals transmitted by the reader in a certain area and range. Only electronic tags pass the area can be effectively read, so that acquisition and reading of the electronic tags have directivity and locality. Arrangement of the information storage, the time storage, and the processor makes time information read by the first directive antenna and the second directive antenna be saved in the time storage, and then the processor reaches a result after comparison and determination. Information of the electronic tags is saved, so that cases of losing data caused by connection break is prevented.
