Embodiment Construction

[0024] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] figure 1 A structural block diagram of the radio frequency identification system of the present invention is schematically shown. Such as figure 1 As shown, the radio frequency identification system 100 applied to the identification of the entry and exit status of the present invention mainly includes: at least two RFID card readers, such as figure 1 The shown first card reader 101 - 1 and second card reader 101 - 2 ; processing unit 102 and storage unit 103 .

[0026] The at least two RFID card readers are arranged at the entrance or the exit, wherein the at least two RFID card readers are arranged along the route of the entrance or the exit with a predetermined distance from each other. The predetermined distance is preferably such that the at least two RFID card readers are not interfered with by each other, and the processing u...

Abstract

The invention provides a radio frequency identification (RFID) system applied to identifying a get-in state and a get-out state. The RFID system comprises at least two RFID card readers arranged at an inlet or an outlet, a processing unit connected with the RFID card readers and a storage unit in signal connection with the processing unit, wherein the two RFID card readers are arranged along a traveling line of the inlet or the outlet in a manner of spacing a preset distance; and the processing unit judges the get-in state and the get-out state of a user with an RFID tag according to reading states of the same RFID tag read by the RFID card readers and a historical record stored in the storage unit. According to the RFID system, the correctness of the RFID card readers for determining the get-in state and the get-out state can be improved; and the RFID system can be widely applied to school guards, intelligent traffics and parking lot systems.

Description

technical field [0001] The invention relates to a radio frequency identification system applied to identification of entering and exiting states. Background technique [0002] "Radio Frequency Identification Technology" is RFID (Radio Frequency IDentification) technology, also known as electronic tags and radio frequency identification. establish mechanical or optical contact between them. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, and the operation is fast and convenient. [0003] The basic components of RFID include tags (Tag): composed of coupling elements and chips, each tag has a unique electronic code, attached to the object to identify the target object; reader (Reader): read (sometimes can also be written) The tag information device can be designed as handheld or fixed; Antenna (Antenna): transmits radio frequency signals between the tag and the reader. [0004] The automatic identification system is an ...
