Please refer to Fig. 2, it is the method flow diagram of the second embodiment of the dynamic antidote of a kind of currency examine magnetic data provided in the specific embodiment of the invention.As shown in the figure, the dynamic antidote of this currency examine magnetic data, comprising:
Step S201: the currency examine magnetic data receiving first banknote, and retain this currency examine magnetic data as correct currency examine magnetic data.
Currency examine magnetic data is obtained by magnetic sensor, and in currency examine process, the currency examine magnetic data of first banknote is correct, can retain this currency examine magnetic data as correct currency examine magnetic data.The currency examine magnetic data of other banknotes can certainly be retained, as long as this currency examine magnetic data is correct.
Step S202: receive current currency examine magnetic data.
Step S203: judge that the 1st row of current currency examine magnetic data is correct, then retain current currency examine magnetic data, and stop detecting current currency examine magnetic data.
When the 1st row of currency examine magnetic data is correct, then show that this currency examine magnetic data is correct, need not continue to detect this currency examine magnetic data, and retain this currency examine magnetic data.
Step S204: judge that the capable data of front n-1 of described current currency examine magnetic data are incorrect, n is more than or equal to 1.
Work as n=1, then judge that the front 0 row data of described current currency examine magnetic data are incorrect, namely current currency examine magnetic data is correct, does not need to continue to detect.
Preferably, described in judge that the capable data of front n-1 of described current currency examine magnetic data are incorrect, comprising:
A1, makes n=1;
A2, obtains the numerical value of the 1st row of n-th line;
A3, judges whether described numerical value is n, if so, then judges that the capable data of n-1 are incorrect; If not, n=n+1, returns step a2.
Step S205: the capable data of n-1 before the correct currency examine magnetic data retained are substituted the capable data of n-1 before current currency examine magnetic data, the banknote number that the correct data from current currency examine magnetic data obtains is substituted the banknote number of the capable data relevant position of front n-1.Specifically see the step S103 in embodiment one, no longer describe here.
The present embodiment is by dynamically correcting the currency examine magnetic data received, the currency examine magnetic data of makeing mistakes dynamically is corrected, can safeguard existing engineering, in order to avoid significantly revise, facilitate follow-up algorithm and Data Detection, and when the 1st row data of currency examine magnetic data are correct, when namely this currency examine magnetic data is correct, stop continuing to detect, decrease workload, improve work efficiency.
Please refer to Fig. 3, it is the method flow diagram of the 3rd embodiment of the dynamic antidote of a kind of currency examine magnetic data provided in the specific embodiment of the invention.As shown in the figure, the dynamic antidote of this currency examine magnetic data, comprising:
Step S301: the currency examine magnetic data receiving first banknote, and retain this currency examine magnetic data as correct currency examine magnetic data.

Step S302: receive current currency examine magnetic data.
Step S303: make n=1.
N represents the line number of currency examine magnetic data.
Step S304: the numerical value obtaining the 1st row of n-th line.
As n=1, then obtain the numerical value of the 1st row of the 1st row; As n=2, then obtain the numerical value that the 2nd row the 1st arranges; As n=3, then obtain the numerical value of the 1st row of the 3rd row; The like.
Step S305: judge that described numerical value is n?
Judge whether described numerical value is n, if so, then perform step S307; If not, then perform step S306, after being finished, return step S304.
Step S306:n=n+1.
Step S307: judge that the capable data of front n-1 are incorrect, performs step S308.
Step S308: judge n>1?
Judge whether n is greater than 1, if so, then perform step S310; If not, then step S309 is performed.
Step S309: retain current currency examine magnetic data, and stop detecting current currency examine magnetic data.
N is not more than 1, then show n=1, and the numerical value that the 1st row the 1st of the currency examine magnetic data of acquisition arranges equals 1, illustrates that current currency examine magnetic data is correct, does not need to continue to detect.
Step S310: by retain correct currency examine magnetic data before the capable data of n-1 substitute current currency examine magnetic data before n-1 capable, the 43rd or 44 of the n-th line from current currency examine magnetic data row obtain banknote number substitute the capable data of front n-1 the 43rd and 44 row banknote numbers.
N is greater than 1, then show that current currency examine magnetic data is made mistakes.Preferably, n is 2 or 3, when n is 2,1 row data before the correct currency examine magnetic data retained are substituted 1 row before current currency examine magnetic data, the banknote number that the 43rd or 44 of the 2nd row from current currency examine magnetic data row obtain is substituted the banknote numbers of the 43rd and 44 row of front 1 row data; When n is 3,2 row data before the correct currency examine magnetic data retained are substituted 2 row before current currency examine magnetic data, the banknote number that the 43rd or 44 of the 3rd row from current currency examine magnetic data row obtain is substituted the banknote numbers of the 43rd and 44 row of front 2 row data.
The present embodiment, by dynamically correcting the currency examine magnetic data received, is dynamically corrected the currency examine magnetic data of makeing mistakes, can be safeguarded existing engineering, in order to avoid significantly revise, facilitate follow-up algorithm and Data Detection.No longer will there is the problem that currency examine magnetic data is made mistakes in amended engineering.Detect counterfeit money machine can be made stably to carry out work with the equipment with cash examining function by carrying out the currency examine magnetic data of makeing mistakes dynamically correcting, this greatly reduces otherwise work, such as, will remodify engineering, causes DSP to crash.
