Identify amount of money error prompting information.
Preferably, papery VAT invoice is converted to by electronic document using OCR optical character recognitions.
Further, capitalization data are converted to small letter data the specific method is as follows：
Different storage of array word figures and multiple keyword are defined, the multiple that traversal is chosen in input character is crucial
Word figure before multiple keyword is converted into small letter number by word；
The capitalization finance data that input OCR is identified, exports corresponding small letter data.
Further, the specific method is as follows for value data comparison：
After the total capitalization of valence tax changes small letter into, whether consistent two small letter numbers are compared；
Identify that obtained every a line unit price multiplies the quantity that identification obtains, the amount of money of the result and identification that are calculated is compared
It is right；
Identify that the obtained amount of money multiplies the tax rate that identification obtains, the amount of tax to be paid that the result and identification being calculated obtain is compared
It is right；
Identify that the amount of money of obtained all rows is added, total amount of money that result and the identification of calculating obtain is compared；
Identify the amount of tax to be paid addition of obtained all rows, the result of calculating and the amount of tax to be paid of identification, which add up to, to be compared；
It identifies that the obtained amount of money is total plus identifies that the obtained amount of tax to be paid, the small letter that the result of calculating adds up to valence tax are compared
It is right.
Compared with prior art, the advantageous effect of the invention reached is：It is produced when can effectively find the OCR identification amount of money
Raw mistake ensure that the accuracy rate of invoice identification, improve the efficiency of value-added tax reimbursement, avoid enterprise staff because of reimbursement system

Description of the drawings
Fig. 1 is the flow chart of the present invention.
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
As shown in Figure 1, being the flow chart of the present invention, include the following steps：
Step 1: papery VAT invoice is converted to electronic document using OCR optical character recognitions, and transfer electricity
In subdocument with the relevant capital and small letter data information of the amount of money；
Include with the relevant capital and small letter data information of the amount of money：Quantity, unit price, the amount of money, the tax rate, the amount of tax to be paid, the amount of money is total, the amount of tax to be paid
Capital and small letter data total, valence tax is total.
Step 2: the capitalization data in data information are converted to small letter data；The specific method is as follows：
Different storage of array word figures and multiple keyword are defined, the multiple that repeatedly traversal is chosen in input character closes
Keyword is simultaneously handled it, then the word figure before multiple keyword is converted into small letter number.Input OCR is identified
Capitalize finance data, exports corresponding small letter data.
Step 3: by every detailed value data with corresponding recognition result compared to pair, will capitalize data with it is transformed
Small letter data are specific as follows compared to pair：
After the total capitalization of valence tax changes small letter into, whether consistent two small letter numbers are compared；
Identify that obtained every a line unit price multiplies the quantity that identification obtains, the amount of money of the result and identification that are calculated is compared
It is right；
Identify that the obtained amount of money multiplies the tax rate that identification obtains, the amount of tax to be paid that the result and identification being calculated obtain is compared
It is right；
Identify that the amount of money of obtained all rows is added, total amount of money that result and the identification of calculating obtain is compared；
Identify the amount of tax to be paid addition of obtained all rows, the result of calculating and the amount of tax to be paid of identification, which add up to, to be compared；
