Waveform debugging system and method thereof applied in F2F decoding system

Abstract

The invention provides a waveform debugging system and a method thereof applied in an F2F decoding system, which can solve the problems that the debugging efficiency is not high and time and effort are wasted when analyzing causes of a swiping card decoding failure if swiping of a magnetic stripe card fails. The waveform debugging system comprises a microconrol unit, a signal acquisition module, an F2F decoding module and an interface multiplexing module, wherein the interface multiplexing module is connected to the microcontrol unit and the signal acquisition module, and is used for receiving a decoding result transmitted by the microcontrol unit and receiving magnetic stripe card digital waveforms transmitted by the signal acquisition module; the microcontrol unit enters a magnetic stripe card waveform output phase when the signal acquisition module is turned on, and controls the interface multiplexing module to output the magnetic stripe card digital waveforms externally; and the microcontrol unit enters a decoding result output phase when the F2F decoding module transmits the decoding result the microcontrol unit, and controls the interface multiplexing module to output decoding result data externally, so that the magnetic stripe card digital waveforms and the decoding data are output externally in real time, thereby being convenient for the user in debugging.

Description

technical field [0001] The invention belongs to the field of magnetic card decoding, and in particular relates to a waveform debugging system and method applied in an F2F decoding system. Background technique [0002] At present, magnetic stripe cards are widely used in various fields, such as bank cards, identification cards or shopping cards. A series of F2F-encoded binary data is recorded on the magnetic stripe card, which contains information such as card number and identification. However, in the F2F decoding system, the failure of swiping the magnetic stripe card is often encountered, which requires analyzing the original waveform of the card to find the cause of the failure. The usual practice is to store the output waveform of the sampling circuit first, and then analyze it, which involves some problems: the output waveform is stored in an external storage area in advance, and the data is redrawn by a specific drawing software, or directly used On-line debugging in...
