Embodiment Construction

[0035] The present invention adds a lock control circuit to control the power supply switch of the active radio frequency identification tag, and cooperates with the opening or closing signal sent by the central controller through the reader, so as to improve the radio frequency identification system in the area Monitoring capabilities, and can save the power consumption of active RFID tags to extend their life.

[0036] Figure 1A A schematic diagram showing the radio frequency identification tag of the first preferred embodiment of the present invention. Such as Figure 1A As shown, the RFID tag 110 includes an antenna 112 , a control circuit 114 , a power supply 116 and a lock control circuit 118 . The antenna 112 is used for receiving an activation signal or an activation signal. The control circuit 114 is electrically connected to the antenna 112 . The control circuit 114 stores a tag identification code, and the power supply 116 outputs a power for the control circuit ...

Abstract

The present invention relates to a radio-frequency identification monitoring method capable of utilizing radio-frequency identification label to control power supply and its system. It is characterized by that several readers are respectively placed on different positions in an area range for receiving a label identification code of a radio-frequency identification label. Said radio-frequency identification label contains a power supplier and a locking control circuit, and the switch of power supplier is controlled by said locking control circuit. Besides, said invention also provides the concrete steps for implementing said radio-frequency identification monitoring method and the concrete application of said method and system.

Description

technical field [0001] The invention relates to a radio frequency identification system, in particular to a radio frequency identification monitoring method and system capable of controlling the power supply of radio frequency identification tags. Background technique [0002] Radio Frequency Identification (RFID) is a non-contact automatic identification technology. It uses radio frequency signals to automatically identify targets and obtain relevant information. The operation is fast and convenient, and the identification operation does not require manual intervention. It can identify dynamic objects and identify multiple tags at the same time. [0003] A complete radio frequency identification system is composed of two parts: the reader (Reader) and the identification controller (Transponder), and the identification controller is usually also called a radio frequency identification tag (RFID Tag). The working principle of the radio frequency identification system is that...
