Problems solved by technology

[0007] 1) The problem that the tag attached to the metal object cannot be read; if the tag is attached to the metal object, the energy provided to the chip will be reduced due to the change of the antenna impedance of the tag
As a result, the reader is not able to receive any or only weak signals from the tags
[0008] 2) The limitation of the reading angle between the tag and the antenna of the

Embodiment Construction

[0064] Please refer to Fig. 1 and Fig. 5, Fig. 1 is the structural representation of LED, light switch, power supply, cooling fan, reader, working status control unit and light controller included in the door control box; Fig. 5 describes the implementation of the present invention Schematic diagram of the working process of the entry and exit system using the "double verification" method as an example.

[0065] As shown in Figure 5, the RFID-based article entry and exit tracking system includes an RFID tag 31 attached to the article, a motion sensor / IR sensor 32, an antenna 33 of multiple readers, a door control box 34, and a back-end data processing unit (not shown). RFID label 31 can be common RFID label, also can be the multiple label (as shown in Figure 2) that is made up of a plurality of RFID labels, the multiple label as shown in Figure 2 is 2 (RFID label 21 and RFID label twenty two). The door control box 34 is installed in the article access place, as shown in Figu...

Abstract

This invention provides an in/out tracking system and a method based on RFID goods including RFID labels, a reader, a working state control unit, reader antennas and a back end data process unit, in which, the working state control unit is connected with the reader to control the working state of the reader, the RFID label is composed of multiple RFID labels and antennas of which are set in angle solving the problem that labels adhered on metals can't be read and improve the limit of reading angles between antennas of labels and readers. This invention also applies a double verification method to carry out double verification to multiple identity verification cards, and the control unit will convert the system from the standby mode to activation working mode only when the verification is successful.

Description

technical field [0001] The invention relates to a logistics tracking system and method, in particular to an RFID-based article entry and exit tracking system and method. Background technique [0002] Radio frequency identification technology is a technology that uses radio frequency signals to achieve contactless transmission of information through spatial coupling (alternating magnetic field or electromagnetic field) and achieves identification purposes through the transmitted information. RFID is widely used in a wide range of fields, including: logistics management, such as shopping malls and supermarket charges, warehousing management to after-sales service, and production and assembly automation; traffic management, such as road tolls and traffic control, container tracking; data statistics, such as animal tracking , sports timing, etc.; security and anti-theft, such as access control identification, item monitoring and anti-theft, etc. [0003] In the logistics contro...
