Embodiment Construction
[0027] The main purpose of the present invention is to provide a radio frequency identification system and its operation method. The radio frequency identification system is different from the traditional wireless network architecture. All the radio frequency identification readers included in it can communicate with the host through the network without additional configuration of network units and high computing requirements. Thereby, the radio frequency identification system proposed by the present invention can achieve the effects of reducing structural complexity and saving cost.
[0028] The first specific embodiment according to the present invention is a radio frequency identification system. In this embodiment, the RFID system includes a total of three UHF RFID readers 142-144, the signal transmission distance of which can reach several meters. Please refer to figure 2 , figure 2 A schematic diagram of the RFID system.
[0029] Such as figure 2 As shown, the RF...

The invention discloses a radio frequency identification system by using radio frequency identification readers, an operation method thereof and a signal conversion device, which simplify the structural complexity of the all radio frequency identification readers and greatly reduce the production cost of the whole radio frequency identification system so as to promote the market competition strength of the radio frequency identification system. The radio frequency identification system comprises a main engine, the signal conversion device and a plurality of radio frequency identification readers; the signal conversion device comprises a network transceiving module and a radio frequency identification transceiving module; the network transceiving module receives a control signal through a network automaton, and generates a conversion signal according to the control signal; the radio frequency identification transceiving module generates a reading instruction according to the conversionsignal and sends the reading instruction through a wireless radio frequency signal; and the radio frequency identification readers selectively generate reading signals or forward the reading instruction according to the reading instruction.
Description
technical field [0001] The invention relates to radio frequency identification, especially a radio frequency identification system using a radio frequency identification reader and its operation method. Background technique [0002] Radio Frequency Identification (RFID) is a non-contact automatic identification technology composed of tags and readers. Its working principle is to place or embed a very small radio frequency identification tag chip on the product, and the product data stored in the radio frequency identification tag chip can be sent to the reader through the radio frequency signal for tracking purposes. Since radio frequency identification technology does not require a lot of manual operations when performing identification work, radio frequency identification technology can be applied to factory automation, goods sales, toll collection systems or vehicle identification. [0003] Radio frequency identification technology is often combined with the general Inte...
