And S241, determining that the current banknote data is incomplete.
And S242, determining that the current banknote data is complete.
S250, losing the incomplete data, and detecting the row number of the banknote data of the next banknote included in the current banknote data.
The incomplete data refers to the banknote data with lost row number of the banknote data or the banknote data with the length smaller than the fixed length.
Specifically, the incomplete data indicates that the banknote data of the collected banknote nos. 1, 2, 3, …, 1376 are incomplete as shown in table two, the banknote data of the collected banknote nos. 1, 2, 3, …, 1376 are lost, and the serial number of the banknote data of the next banknote included in the current banknote data is detected, that is, the banknote data of the collected banknote nos. 1, …, 10 are shown in table two.
Specifically, whether the acquisition line number of the error line is 1 or not is detected, and if the acquisition line number of the error line is 1, the current line data is stated to be frame header data, that is, the error line data is stated to be frame header data of another piece of paper money data.
And S260, acquiring the banknote data continuous to the row number of the banknote data of the next banknote.
And the next paper currency is next paper currency next to the current paper currency in the paper currency channel.
In a specific example, if the current banknote data is as shown in table two, the banknote data of the next banknote next to the current banknote in the channel is as shown in table three:
watch III
The data of the collected line numbers 1, …, and 10 in the second table are the first ten lines of banknote data of the next banknote data, and the data of the collected line numbers 11, …, and 1386 in the third table are the remaining data of the next banknote data. The remaining data for collection line numbers 1, …, 10 in table three are banknote data for the next banknote next to the next banknote in the lane.
And S270, splicing the included banknote data of the next banknote with the acquired banknote data with continuous line numbers to generate banknote data of the next banknote according with the fixed length as the current banknote data.
Specifically, if the current banknote data is as shown in table two and the banknote data of the banknote next to the current banknote in the banknote path is as shown in table three, the data of the collection line numbers 1, …, 10 in table two and the data of the collection line numbers 11, …, 1386 in table three may be concatenated to generate the banknote data of the banknote next to the fixed length as the current banknote data.
And S280, if the current banknote data is incomplete, regarding the banknote corresponding to the current banknote data as a counterfeit banknote or a waste banknote.
In a specific example, data frame format detection is carried out on received data (the data frame format is defined by a communication protocol established between the FPGA and the DSP); the first line of data of one data is frame header data, the first column is acquisition line number, and the acquisition line number is 1, 2, 3, … and N (N is the total acquisition line number of data acquisition). When the frame information of the data is detected, if the error condition of the acquisition line number is met, whether the acquisition line number of the error line is 1 is detected, and if the acquisition line number of the error line is 1, the current line data is the frame header data, namely the frame header data of the next piece of paper money data is indicated by the error action. And if the acquisition line number of the error line is not 1, indicating that the current line data is not the frame header data, and not performing data splicing. If the error action is the frame head data, the line data is stored to the end column data. And detecting whether the first line acquisition line number of the second data can be continuous with the last line acquisition ending number. And judging whether the data of the wrong row number frame head of the piece of data is at the same position as the previous piece of data, if so, splicing the data of the latter half of the previous piece of data with the data of the previous half of the previous piece of data, judging whether the data of the latter half of the previous piece of data is the same piece of data, and simultaneously carrying out counterfeit identification on the spliced data.
Optionally, the method further includes:
if the number of the paper money which is continuously identified as true paper money exceeds a preset paper threshold according to the spliced paper money data, judging whether the difference value between the obtained number of the paper money and the current serial number of the paper money is greater than the preset threshold;
the number of the acquired paper money can be the number of withdrawn paper or the number of deposited paper. If the acquired number of the banknotes is the number of the banknotes when the user withdraws the banknotes, the banknotes can be acquired through the amount of the banknotes input by the user. If the obtained number of the paper money is the number of the paper money deposited by the user, the number of the paper money deposited by the user can be obtained firstly, and then the paper money can be identified.
Specifically, if the number of the paper sheets continuously identified as true paper money exceeds a preset paper threshold value according to the spliced paper money data, the situation that the machine cannot run due to the fact that the data source corresponding to the remaining paper money is crossed and wrong due to the fact that the obtained paper money data are incomplete can be effectively prevented through splicing the paper money data, when the truth is verified subsequently, the error rate is high, a large number of paper money is mistakenly judged as false paper money and returned or mistakenly judged as waste paper money, and therefore the waste paper money box is quickly full of the paper money box.
If the time sequence is greater than or equal to the preset threshold, informing a Field Programmable Gate Array (FPGA) to correct the time sequence, and if the time sequence is less than the preset threshold, continuing executing the data splicing step.
And sending the instruction of the time sequence to be corrected to the FPGA, and correcting the time sequence by the FPGA.
Specifically, if the difference between the acquired number of banknotes and the current serial number of the banknotes is greater than or equal to the preset threshold, it indicates that a lot of banknotes need to process the banknote data, and the FPGA can be notified to perform timing correction, so as to solve the problem fundamentally.
In a specific example, if 5 pieces of abnormal condition data are continuously generated and the splicing data are true banknotes at the same time, judging whether the difference value between the number of withdrawn banknotes and the serial number of the current banknotes is greater than 10; if the difference is less than 10, continuing to process according to the third step; and if the difference value is larger than 10, adjusting and correcting the FPGA sending time sequence.
According to the technical scheme of the embodiment, under the condition that the current banknote data is incomplete, incomplete data is lost, the line number of the banknote data of the next banknote included in the current banknote data is detected, the banknote data continuous with the line number of the banknote data of the next banknote included is acquired, the banknote data of the next banknote included and the acquired banknote data continuous with the line number are spliced, and the banknote data of the next banknote conforming to the fixed length is generated and serves as the current banknote data. The situation that the machine cannot run due to the fact that a waste paper money box is full quickly and the false identification rate of the paper money can be improved is avoided.
