The invention provides an Internet of Things wireless time-sharing RFID (Radio Frequency Identification Device) terminal. The RFID terminal comprises a power supply unit, a transmit-receive control unit, a radio frequency read-write unit, a radio frequency time-sharing control unit and a plurality of card reading antennas, an output port of the radio frequency time-sharing control unit is connected with the plurality of card reading antennas, and the radio frequency time-sharing control unit is used for sequentially and instantaneously activating the plurality of card reading antennas; a control port of the transceiving control unit is connected with a control port of the radio frequency time-sharing control unit, and the transceiving control unit is used for controlling the radio frequency time-sharing control unit to sequentially and instantaneously activate the plurality of card reading antennas; a first communication port of the radio frequency read-write unit is connected with a communication port of the transmit-receive control unit, a second communication port of the radio frequency read-write unit is connected with an input port of the radio frequency time-sharing control unit, and the radio frequency read-write unit is used for reading and writing an RFID card in the card reading antenna. According to the invention, a plurality of RFID cards can be read and written quickly in a short time, and the plurality of RFID cards can be read and written approximately at the same time.
Description
technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a wireless time-sharing RFID terminal of the Internet of Things. Background technique [0002] RFID is the English abbreviation of radio frequency identification. The IoT RFID terminal is an automatic identification device that can read and write RFID card data. It usually includes a controller, RFID card reader and antenna, and generally includes a wireless module for interacting with user equipment. . Usually, to realize the information reading of an RFID card, a card reader chip and an RFID read-write antenna are required. In many RFID system applications, it is necessary to quickly read and write multiple RFID cards in a short time. In order to achieve this purpose, the usual practice is to read and write an RFID card through a card reader chip and then read and write another RFID card. The reading and writing speed of this method depends on the speed of cha...
