Embodiment Construction

[0024] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, a visual RFID positioning system based on LED, which includes a visual positioning device and a handheld reader. The visual positioning device includes RFID electronic tags, LEDs and wireless communication modules. The handheld reader includes a card reader and a wireless communication module. Input the target number or scan the RFID tag information on the handheld reader, when there is an object identified by the RFID tag in the RFID network, the LED on the target item will flash.

[0026] The system deployment of the present invention is as figure 2 As shown, the handheld reader receives user input or swipes the RFID tag card to input the RFID tag information of the item to be found, and sends the query information to the RFID network through the wireless module. If the tag exists in the RFID network, the visual positioning dev...

Abstract

The invention discloses an LED-based visual RFID positioning system and method. The system includes a visual positioning device and a hand-held reader; the visual positioning device includes an RFID label, an LED and a wireless communication module. The RFID tag is used to identify the article object, and the LED is used for flashing prompts after the RFID tag object is identified. The wireless communication module uses hardware modules such as Zigbee and nFR24101 to transmit data information; the handheld reader includes a card reader and a wireless communication module. . The card reader module is used to read RFID tag information, and the wireless communication module uses Zigbee, nFR24l01 and other hardware modules to transmit data information. The present invention is convenient to be deployed in an indoor or outdoor environment, and the visual positioning can accurately find the position of the item and perform real-time positioning display through the smart device.

Description

technical field [0001] The invention relates to an LED-based visual RFID positioning system and method, belonging to the technical field of positioning systems. Background technique [0002] Radio Frequency Identification (RFID) is a communication technology that uses radio frequency for non-contact two-way communication to achieve identification purposes and exchange data. It can identify high-speed moving objects or stationary objects and simultaneously identify multiple targets. Known as one of the ten most important technologies in the 20th century. A typical RFID system mainly includes three parts: electronic tag (Tag), reader (Reader) and data processing subsystem. The basic working principle of the system: the reader sends a radio frequency signal of a certain frequency through the transmitting antenna. When the tag enters the working area of ​​the transmitting antenna, an induced current is generated, and the tag obtains energy and is activated; the tag sends inform...
