Description
Technical field
The utility model relates to a kind of induction structure of radio circuit, refers to that more particularly a kind of induction structure that utilizes magnetic conductor to increase the magnetic field intensity of inductive coil part reaches by its POS machine that constitutes.
Background technology
Radio-frequency card (being called for short the RF card) is a kind of integrated circuit card with wireless mode transmission data, and it has distinctive advantages such as data processing and safety certification function.Radio-frequency card is non-contact IC card again; Being born in the beginning of the nineties, is a new technology that grows up recent years in the world, and it successfully radio frequency is known technology and the IC-card technology combines; Having solved passive (non-transformer in the card) and contacted this difficult problem with exempting from, is a quantum jump of field of electronic devices.Owing to exist magnetic card and the incomparable advantage of Contact Type Ic Card, make it once appearance, just cause immediately widely and pay close attention to, and applied with surprising rapidity.Non-contact IC card is by the IC chip, and induction antenna is formed, and is sealed in the standard PVC card no exposed parts fully.The read-write process of non-contact IC card is usually by accomplishing read-write operation through radiowave between non-contact IC card and the read write line.
Non-contact IC card itself is passive body; When read write line when sticking into capable read-write operation, the signal that read write line sends is made up of two parts stack: a part is a power supply signal, this signal by card receiver after; Produce resonance with the L/C of itself, produce a transient energy and supply with chip operation.Another part then is a combined data signal, and commander's chip is accomplished data, modification, storage etc., and returns to read write line.By the formed read-write system of non-contact IC card, no matter be hardware configuration, or operating process has all obtained very big simplification, simultaneously by means of advanced management software, but the mode of operation of off line all makes the reading and writing data process more simple.Compare with Contact Type Ic Card, contactless card have the reliability height, easy to operate fast, can be suitable for advantages such as multiple application and encryption performance are good.
Usually the required distance between radio-frequency card and the radio frequency induction reading device (being main frame) is closer; Be because radio frequency induction reading device relatively simple for structure on the main frame; The Distribution of Magnetic Field of inductive coil is (as depicted in figs. 1 and 2) around main frame; To spread out, thereby weaken the magnetic field intensity that is passed on the radio-frequency card.When the induction of radio-frequency card is insensitive, can cause swiping the card unsuccessful (can't read normally), weakening of magnetic field intensity also can increase the time for reading of radio-frequency card.Shown in figure 10, be the Distribution of Magnetic Field schematic perspective view of the induction structure of conventional P OS machine; The signal waveform that inductive coil sends is outwards infinitely to extend out circlewise around inductive coil, disappears until the signal intensity decline.The signal waveform of being sent by inductive coil like this can interfere with the signal of electronic element such as CPU on the mainboard, may influence the operate as normal of machine.
