The invention discloses a novel microcircuit IC read head. The read head includes: a read head coil, which is used to send a modulated carrier signal outwards or receive a radio frequency signal; an IC read head chip, which is used to control the read head coil to send the modulated carrier signal outwards or receive the radio frequency signal, and is used to decode the radio frequency signal received by the read head coil and send a decoded radio frequency signal to a CPU; the CPU, which is used to generate a control signal after carrying out processing according to the received decoded radio frequency signal; and two anti-static circuits, which are connected with the IC read head chip and are used to shield and filter static voltage. According to the read head, static interference can be effectively prevented through adding the two anti-static circuits on pins, which are connected with the chip and the coil, to form a two-stage protection circuit, normal card swiping is not impacted at the same time, and normal and stable working of the card reading chip is guaranteed.
Description
technical field [0001] The invention relates to the field of wireless radio frequency, in particular to a novel microcircuit IC reading head and a working method thereof. Background technique [0002] The current industrial production site will generate a lot of static electricity, and the instantaneous voltage during electrostatic discharge is very high, which will interfere with the card-reading chip on the reading head hanging in and out of the station, resulting in abnormal and unstable card swiping, and even damage to the chip. Contents of the invention [0003] The invention provides a novel microcircuit IC reading head for solving the technical problem of static interference of the IC reading head. [0004] The invention provides a novel microcircuit IC read head, which includes: a read head coil for sending out a modulated carrier signal or receiving a radio frequency signal; [0005] The IC reading head chip is used to control the reading head coil to send out th...
