Embodiment 1

[0044] A radio frequency identification device, such as Figure 1 to Figure 6 As shown, a main control module, a radio frequency reading and writing module, a voice module, a display device and a power supply module are provided, and a USB charging module is also provided.

[0045] The radio frequency reading device is used for communicating with the supporting IC card, displaying the information in the IC card through the display device, and at the same time making voice broadcast by the voice module. The power supply module provides working voltage for other modules, and the USB charging module makes the charging method of the radio frequency reading device more convenient and flexible.

[0046] The main control module is the core of the radio frequency reading device. The main control module communicates with the IC card, displays the information in the IC card through the display device, and controls the voice module to perform voice broadcast. like figure 2 As shown, t...

[0064] A radio frequency reading device, the other structure is the same as that of Embodiment 1, the difference is that: the components with the following parameters are specifically used.

[0065] Specifically, the capacitor C23 is set to 10 microfarads, the resistor R8 is set to 10 kohms, the capacitors C21 and C22 are both set to 22 picofarads, and the frequency of the crystal oscillator Y2 is 12M.

[0066] Resistor R5 is set to 5.1 kohms, resistor R6 is set to 32 ohms, resistor R7 is set to 10 kohms, capacitors C8 and C9 are set to 22 picofarads, capacitors C10 and capacitor C11 are set to 100 picofarads, capacitors C12 and capacitor C13 , capacitor C14, and capacitor C15 are all set to 47 picofarads, capacitor C16 is set to 104 picofarads, capacitors C17 and capacitor C18 are both set to 15 picofarads, and the frequency of crystal oscillator Y1 is 27.12M.

[0067] Capacitor C1 is set to 104 picofarads, capacitor C2 is set to 105 picofarads, capacitor C3, capacitor C4, and ...

Embodiment 3

[0073] A radio frequency identification system is composed of an IC card and the radio frequency identification device of any one of the above-mentioned embodiment 1 or 2. Specifically, the IC card is set as a MIFARE card, and the radio frequency reading device communicates with the IC card.

[0074] The MIFARE card is a contactless IC card manufactured by NXP Company (formerly Philips Semiconductor Company), and its specific structure will not be repeated here. The electrical part of the MIFARE card is composed of an antenna and ASIC. All the energy required for the chip in the MIFARE card to work is provided by the radio frequency reading device. The radio frequency reading device sends a group of electromagnetic waves with a frequency of 13.56MHZ to the IC card through the antenna. There is an LC resonant circuit in the IC card, whose frequency is the same as the frequency emitted by the radio frequency reading device. Under the excitation of electromagnetic waves, the LC r...

Description

technical field [0001] The invention relates to the technical field of radio frequency reading, in particular to a radio frequency reading device and a radio frequency identification system. Background technique [0002] RFID technology is hailed by the global high-tech field as the technology with the most market prospect and the most changing human life style and high-tech industry. [0003] Compared with the contact IC card, the non-contact IC card inherits the advantages of the contact IC card, such as large capacity and high security, and overcomes the disadvantages of pollution, wear, static electricity and access only when the card is inserted due to exposed contacts. Moreover, non-contact IC cards also have some other superior properties, such as quick operation, strong anti-interference, high reliability, long life, and multiple working distances. It is based on these advantages that non-contact IC cards are widely used in bus automatic ticketing systems, campus ca...
