Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail. Furthermore, in the description of the present application and the appended claims, the terms "first," "second," "third," and the like are used for distinguishing between descriptions and not necessarily for describing or implying relative importance.
The embodiment of the application provides a method and a device for detecting the number of paper money in a paper money box, terminal equipment and a storage medium, and can improve the accuracy of detecting the number of paper money in the paper money box. It should be understood that the execution subject of the various method embodiments of the present application is financial equipment such as an ATM machine, or other relevant terminal equipment.
Referring to fig. 1, a method for detecting the number of banknotes in a banknote cassette in an embodiment of the present application is shown, including:
101. recording the paper money attribute of each paper money to enter the paper money box in the process of detecting the paper money;
in the process of cash depositing and withdrawing transactions, the currency detecting device is adopted to detect each paper currency entering the currency box, and record the characteristics of the type, the version, the denomination, the stain, the unfilled corner and the like of the paper currency, so that the attribute information of the paper currency, such as the type, the version, the denomination, the stain grade, the unfilled corner condition and the like of each paper currency entering the currency box, is obtained.
102. Respectively determining the weight error value of each paper currency according to a pre-constructed paper currency weight comparison table and the paper currency attribute of each paper currency;
and then, respectively determining the weight error value of each piece of paper currency according to a pre-constructed paper currency weight comparison table and the paper currency attribute of each piece of paper currency. The banknote weight comparison table records the corresponding relation between the banknote attributes and the banknote weights, the weight error value of any one target banknote is the weight difference value between the target banknote and a single standard banknote, and the standard banknote has the designated banknote attributes. For example, considering the denomination attribute of the banknote, the standard banknote is a 100-dollar banknote, and the target banknote is a 50-dollar banknote, the weight error value of the target banknote is the weight difference between the 50-dollar banknote and the 100-dollar banknote. Or, considering the category, version and denomination attributes of the banknotes, the standard banknote is the 100-yuan RMB of the 2015-year version, and the target banknote is the 50-yuan RMB of the 2009 version, the weight error value of the target banknote is the weight difference between the 50-yuan RMB of the 2009 version and the 100-yuan RMB of the 2015-year version.
Specifically, the weight error value of the target banknote may be determined according to the following steps:
(1) Acquiring the paper money attribute of the target paper money;
(2) Searching a first weight of a single banknote corresponding to the banknote attribute of the target banknote and a second weight of a single banknote corresponding to the banknote attribute of the standard banknote from the banknote weight comparison table;
(3) And calculating the difference between the first weight and the second weight to obtain a weight error value of the target paper money.
TABLE 1
Taking the banknote weight comparison table shown in table 1 as an example, assuming that the target banknote is a banknote of 50 yuan denomination and the standard banknote is a banknote of 100 yuan denomination, a single banknote of 1.2g corresponding to 50 yuan denomination and a single banknote of 1.5g corresponding to 100 yuan denomination can be found from table 1. Then, the weight error value of the target banknote is 1.2g-1.5g = -0.3g.
Further, the banknote weight comparison table includes a banknote category weight comparison table, a banknote version weight comparison table, a banknote denomination weight comparison table, a banknote defect weight comparison table and a banknote defect weight comparison table, the banknote attributes include the category, version, denomination, defect grade and defect condition of the banknote, and the searching for the first weight of a single banknote corresponding to the banknote attribute of the target banknote from the banknote weight comparison table includes:
(1) Searching a third weight of a single banknote corresponding to the type of the target banknote from the banknote type weight comparison table;
(2) Searching the fourth weight of the single paper currency corresponding to the version of the target paper currency from the paper currency version weight comparison table;
(3) Searching a fifth weight of a single banknote corresponding to the denomination of the target banknote from the banknote denomination weight comparison table;
(4) Looking up a sixth weight of a single banknote corresponding to the insult level of the target banknote from the banknote insult weight comparison table;
(5) Searching a seventh weight of a single banknote corresponding to the unfilled corner condition of the target banknote from the banknote unfilled corner weight comparison table;
(6) Subtracting 4 times of the second weight from the sum of the third weight, the fourth weight, the fifth weight, the sixth weight and the seventh weight to obtain the first weight.
In practical operation, the attributes of the banknote may be separated, and a banknote weight comparison table may be constructed for each attribute, and specifically, the banknote weight comparison table may include 5 tables, such as a banknote category weight comparison table, a banknote version weight comparison table, a banknote denomination weight comparison table, a banknote contamination weight comparison table, and a banknote unfilled corner weight comparison table. After obtaining the banknote attributes such as the type, version, denomination, stain level and unfilled corner condition of the target banknote, the weight x of a single banknote corresponding to the type of the target banknote can be searched from the banknote type weight comparison table 1 Looking up the weight x of a single banknote corresponding to the version of the target banknote from the banknote version weight comparison table 2 Looking up the weight x of a single banknote corresponding to the denomination of the target banknote from the banknote denomination weight look-up table 3 Looking up the weight x of a single banknote corresponding to the insult level of the target banknote from the banknote insult weight look-up table 4 Looking up the weight x of the single note corresponding to the corner defect condition of the target note from the note corner defect weight comparison table 5 . Then, the first weight g 1 ＝x 1 +x 2 +x 3 +x 4 +x 5 -4g 2 Wherein g is 2 Representing the weight of standard paper currency, the weight error value of target paper currency is g 1 -g 2＝ x 1 +x 2 +x 3 +x 4 +x 5 -5g 2 I.e. the sum of the weight error values corresponding to the respective banknote attributes.
103. Weighing the total weight of the paper money in the paper money box after adding the paper money in the paper money box;
specifically, a banknote weighing device may be provided in the banknote box, and after the banknote box is filled with banknotes, the weighing device is used to weigh the total weight of the banknotes in the banknote box.
104. And determining the number of the paper money in the paper money box according to the total weight of the paper money, the weight of a single piece of the standard paper money and the weight error value of each paper money.
And finally, determining the number of the paper money in the paper money box according to the total weight of the paper money, the weight of a single standard paper money and the weight error value of each paper money. In a traditional banknote weighing method, the total weight of weighed banknotes is generally directly divided by the weight of a single standard banknote to obtain the number of banknotes in a banknote box. However, the number of banknotes obtained by conventional banknote weighing methods is not accurate, since banknotes stored in the banknote cassette may have different attributes (e.g. different types, different denominations, different versions), etc., whereas banknotes of different attributes usually have different weights. In view of this, in the embodiment of the present application, when determining the number of the banknotes, a weight error value of each banknote entering the banknote box is considered, so as to offset a weight error between the non-standard banknote and the standard banknote having different banknote attributes, and effectively improve accuracy of detecting the number of the banknotes in the banknote box.
In the currency detection process, the attribute of each piece of currency to enter the currency box, such as the attribute of the category, denomination, version and the like of the currency, is recorded. Then, according to the pre-constructed paper money weight comparison table and the paper money attribute of each paper money, the weight error value of each paper money, namely the difference between the weight of the paper money and the weight of the standard paper money is respectively determined. After the total weight of the paper money in the paper money box is obtained through weighing, the number of the paper money in the paper money box can be determined by combining the total weight of the paper money, the weight of a single piece of standard paper money and the weight error value of each piece of paper money, so that the weight error between the non-standard paper money and the standard paper money with different paper money attributes can be offset through operation, and the accuracy of detecting the number of the paper money in the paper money box can be effectively improved.
Referring to fig. 2, another method for detecting the number of banknotes in a banknote cassette in an embodiment of the present application is shown, including:
201. recording the attribute of each paper currency to be entered into the currency box in the currency detection process;
202. respectively determining the weight error value of each paper currency according to a pre-constructed paper currency weight comparison table and the paper currency attribute of each paper currency;
203. weighing the total weight of the paper money in the paper money box after adding the paper money in the paper money box;
steps 201-203 are the same as steps 101-103, and reference may be made to the related descriptions of steps 101-103.
204. Dividing the total weight of the paper money by the weight of a single standard paper money to obtain the initial number of the paper money;
after the total weight of the paper money in the paper money box is weighed, the total weight of the paper money is divided by the weight of a single standard paper money to obtain the initial number of the paper money. For example, if the standard banknotes are 100 yuan RMB, the weight is 1.5 g/piece, and the total weight of the weighed banknotes is 1020g, the initial number of banknotes is 1020/1.5= 680.
205. And correcting the initial number of the banknotes by combining the weight error value of each banknote to obtain the number of the banknotes in the banknote box.
If the standard banknotes with the same attribute are stored in the banknote box, the obtained initial banknote quantity is relatively accurate. In practice, however, banknotes of various attributes are stored in the banknote cassette, and in order to obtain an accurate banknote count result, the initial banknote count needs to be corrected in combination with the weight error value of each banknote.
The specific modification mode may include:
(1) Calculating the sum of the weight error values of each paper currency to obtain error weight;
(2) Dividing the error weight by the weight of a single piece of standard paper money to obtain an error quantity;
(3) And calculating the sum of the initial number of the paper money and the error number to obtain the number of the paper money in the paper money box.
For example, the initial number of the paper money is 680, and the sum of the calculated weight error values of the paper money entering the paper money box is 150g as the error weight; dividing the error weight by 1.5g of the weight of a single standard banknote to obtain 150g/1.5g of error pieces which are not less than 100; finally, the sum of the initial banknote number and the error number is calculated, namely 680+100=780, and the sum is used as the corrected banknote number in the banknote box.
In the currency detection process, the attribute of each piece of currency to enter the currency box, such as the attribute of the category, denomination, version and the like of the currency, is recorded. Then, according to the pre-constructed paper money weight comparison table and the paper money attribute of each paper money, the weight error value of each paper money, namely the difference between the weight of the paper money and the weight of the standard paper money is respectively determined. After the total weight of the paper money in the paper money box is obtained through weighing, the number of the paper money in the paper money box can be determined by combining the total weight of the paper money, the weight of a single piece of standard paper money and the weight error value of each paper money. Compared with the first embodiment of the present application, this embodiment proposes a specific way to determine the number of banknotes in the banknote cassette according to the total weight of the banknotes, the weight of a single standard banknote and the weight error value of each banknote.
Referring to fig. 3, another method for detecting the number of banknotes in a banknote cassette in an embodiment of the present application is shown, including:
301. recording the attribute of each paper currency to be entered into the currency box in the currency detection process;
302. respectively determining the weight error value of each paper currency according to a pre-constructed paper currency weight comparison table and the paper currency attribute of each paper currency;
303. weighing the total weight of the paper money in the paper money box after adding the paper money in the paper money box;
steps 301-303 are the same as steps 101-103, and reference may be made to the related descriptions of steps 101-103.
304. Calculating the sum of the weight error values of each paper currency to obtain error weight;
305. subtracting the error weight from the total weight of the paper money to obtain a corrected weight;
306. and dividing the corrected weight by the weight of a single standard paper currency to obtain the number of the paper currencies in the cash box.
For steps 304-306, the following is illustrated: assuming that the total weight of the weighed paper money is 1020g, and the weight of a single piece of standard paper money is 1.5g, the sum of the calculated weight error values of the paper money entering the paper money box is-150 g, and the sum is used as the error weight; subtracting the error weight from the total weight of the paper currency to obtain corrected weight of 1020g- (-150 g) =1170g; finally, the corrected weight is divided by the weight of a single standard banknote to obtain the banknote number of the banknote box of 1170g/1.5g = 780. The principle of this processing method is to correct the total weight of the weighed banknotes to a corrected weight (i.e. the weight that should be assumed if all the banknotes in the banknote cassette are standard banknotes), and finally divide the corrected weight by the weight of a single standard banknote, thereby obtaining a relatively accurate number of banknotes.
In the currency detection process, the attributes of each piece of currency to enter the currency box, such as the attributes of the category, denomination and version of the currency, are recorded. Then, according to the pre-constructed paper money weight comparison table and the paper money attribute of each paper money, the weight error value of each paper money, namely the difference between the weight of the paper money and the weight of the standard paper money is respectively determined. After the total weight of the paper money in the paper money box is obtained through weighing, the number of the paper money in the paper money box can be determined by combining the total weight of the paper money, the weight of a single piece of standard paper money and the weight error value of each piece of paper money. Compared with the second embodiment of the present application, this embodiment provides another specific way to determine the number of banknotes in the banknote cassette according to the total weight of the banknotes, the weight of a single standard banknote, and the weight error value of each banknote.
Referring to fig. 4, another method for detecting the number of banknotes in a banknote cassette in an embodiment of the present application is shown, including:
401. in the process of currency detection, the number of the paper currencies to enter the currency box and the attribute of each paper currency are recorded;
in the process of currency detection, the embodiment not only records the attribute of each piece of paper currency to be entered into the paper currency box, but also records the number of the paper currencies to be entered into the paper currency box as the logic counting of the paper currencies.
402. Respectively determining the weight error value of each paper currency according to a pre-constructed paper currency weight comparison table and the paper currency attribute of each paper currency;
403. weighing the total weight of the paper money in the paper money box after adding the paper money in the paper money box;
404. determining the number of the paper money in the paper money box according to the total weight of the paper money, the weight of a single piece of the standard paper money and the weight error value of each paper money;
steps 402-404 are the same as steps 102-104, and reference may be made specifically to the description of steps 102-104.
405. And if the difference value between the number of the paper money to enter the paper money box and the number of the paper money in the paper money box exceeds a preset threshold value, outputting alarm information.
After determining the number of banknotes in the banknote cassette, the difference between the number of banknotes to be entered into the banknote cassette (logical count) recorded in step 401 and the number of banknotes in the banknote cassette (physical count) determined in step 404 is determined. Under normal conditions, the number of paper money to enter the paper money box and the number of paper money in the paper money box should be the same or similar, if the difference between the two is large, it indicates that abnormal conditions such as manual modification of physical counting of the paper money box, manual stealing of paper money, or false paper money error exist, and at the moment, alarm information is output to remind relevant paper money box monitoring personnel to pay attention.
In the currency detection process, the number of the banknotes to enter the currency box and the attributes of each banknote, such as the category, denomination and version of the banknote, are recorded. Then, according to the pre-constructed paper money weight comparison table and the paper money attribute of each paper money, the weight error value of each paper money, namely the difference between the weight of the paper money and the weight of the standard paper money is respectively determined. After the total weight of the paper money in the paper money box is obtained through weighing, determining the number of the paper money in the paper money box by combining the total weight of the paper money, the weight of a single piece of standard paper money and the weight error value of each paper money; and finally, if the difference value between the number of the paper money to enter the paper money box and the number of the paper money in the paper money box exceeds a preset threshold value, outputting alarm information. Through the arrangement, the abnormal condition of the number of the paper money in the paper money box can be found in time.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
