Description

Cash-out control method and system of financial terminal and financial terminal

Technical Field

Background

With the application and development of computer technology and communication technology in the financial industry, people rely on financial self-service terminals (such as Automatic Teller Machines (ATMs)) more and more strongly. At present, financial self-service terminals mostly dig out banknotes from a banknote box one by one during banknote output, then select and identify the banknotes, the qualified banknotes are stacked in a temporary storage device, the unqualified banknotes are recovered in a waste banknote box, the process is generally called banknote counting, the number of the banknotes needed by the service is counted, and then the banknotes stacked on the temporary storage device are sent to a banknote outlet to be taken by a user. At present, the currency counting performance of a cassette mechanism is generally 8 sheets per second, if the cash is withdrawn in large amount, the time for counting the currency is longer, in addition, the time for recovering the currency is possibly consumed, and if the quality of the currency in a currency box is poorer, the recovery rate of the currency is higher, the time for counting the currency is longer. Generally, 500 high quality banknotes are dispensed in at least one minute or more, and if the quality of the banknotes is low, two minutes or more may be required, and sometimes even a banknote jam occurs. Because the cash output amount is several times, even dozens of times, of the ordinary money withdrawing business when the large amount of cash is output, the probability of the cash clamping of the machine core is several times, dozens of times or even higher than that of the ordinary money withdrawing business, and the utilization rate of the machine core is not high in terms of actual working time; meanwhile, when large amount of money is withdrawn, the number of the dispensed money is large, the money is dispensed for a long time, and the cash rushing business is multiplied due to the increase of the failure rate of the money clamping, so that a lot of unnecessary expenses are brought to a bank system and a network.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

After receiving withdrawal information of a user, a financial terminal firstly acquires the withdrawal amount of the user, and all bundled note information and loose note information of the current financial terminal; and distributing the banknotes for the money withdrawing task of the user according to the banknote bundling information and the banknote scattering information, calling a banknote distribution result, and respectively carrying out banknote bundling and banknote scattering according to the called banknote distribution result. Therefore, when a user withdraws money in large amount, a mode of combining whole bundle of cash and scattered cash is adopted. The number of the bundled banknotes is generally larger, the whole bundle of banknotes is output, the banknote output time is shortened, and the probability of banknote output faults is reduced.

In order to explain the technical means of the present invention, the following description will be given by way of specific examples.

The first embodiment is as follows:

fig. 1 is a flowchart illustrating a cash dispensing control method of a financial terminal according to a first embodiment of the present invention, which is detailed as follows:

at present, financial terminal equipment generally only can dispense loose banknotes when performing a user deposit task, and for example, a circulating all-in-one machine and a cash dispenser put into operation in the market need to count and verify banknotes one by one, and then deliver the banknotes to a user. The cash dispenser is very suitable for small-amount cash dispensing occasions, and for large-amount cash dispensing, particularly for large-amount cash dispensing, the cash dispensing mode of loose cash is easy to cause accidents such as cash jamming and the like, so that the transaction is failed; under the condition, the business roll-back processing process is complicated, especially, the situation that the money is not output to meet the withdrawal amount due to the abnormal money output under the condition that a user takes a part of the money is caused, and the situation that the money is not output to meet the withdrawal amount is easy to bring dissatisfaction to large bank customers and great damage is brought to high-quality bank services due to large related amount. Therefore, in order to make up for the deficiency of the loose-banknote dispensing method in the large-amount dispensing, the method for controlling the dispensing of the banknotes at the financial terminal according to this embodiment first:

step S11, obtaining the money drawing amount of the user, the money bundling information and the money scattering information of the current financial terminal;

in the step, a money amount M of the current withdrawal of the user is obtained, and money bundling information and money scattering information of the current financial terminal are obtained at the same time, wherein money bundling refers to putting a plurality of banknotes with the same denomination together to form a bundle and storing the bundle in financial equipment, for example, 20 banknotes with the denomination of 100 yuan are bundled into a bundle, or 50 banknotes with the denomination of 20 yuan are bundled into a bundle, and how to set each bundle of banknotes can also be set according to needs. Loose banknotes are individual banknotes of various denominations, for example a banknote of 50 dollars denomination. The money binding information includes: bound note type n, single bound amount A of each bound note₁，A_2,，…，A_nAnd the number X of usable bound banknotes for each bound banknote₁，X_2,，…，X_nX belongs to Z; the loose money information comprises: kinds m of loose banknotes, denomination B of each kind of loose banknotes₁，B_2,，…，B_mAnd the number of loose banknotes available for each denomination Y₁，Y_2,，…，Y_m，Y∈Z。

Step S12, the money distribution calculation is carried out according to the money drawing amount of the user, the money bundling information and the money scattering information to obtain the money distribution result;

distributing the money according to the money drawing amount M of the user and the money bundling and scattering information of the current financial terminal; setting the quantity of each bundle of money needed by the current user when the money drawing amount M is distributed as x₁，x_2,，…，x_nX is an element of Z; the required number of loose banknotes is y₁，y_2,，…，y_mY is equal to Z; wherein x is more than or equal to 0₁≤X₁，0≤x_2,≤X_2,，…，0≤x_n≤X_n；0≤y₁≤Y₁，0≤y_2,≤Y_2,，…，0≤y_m≤Y_m. Then there are: m ═ A₁x₁+A₂x₂+...+A_nx_n+B₁y₁+B₂y₂+...+B_my_m。

As shown in fig. 2, preferably, the calculating of the money distribution according to the money amount withdrawn by the user, the money bundling information, and the money scattering information to obtain a money distribution result includes:

step S121, distributing the whole bundle of dispensed banknotes according to the withdrawal amount of the user and the money bundling information to obtain a money bundling and distributing scheme and a money distributing mantissa;

step S122, distributing the single-sheet cash according to the cash distribution mantissa and the loose cash information, and determining a loose cash distribution scheme;

step S123, selecting one of the bundled note distribution schemes, and selecting one of the scattered note distribution schemes according to the note distribution mantissa corresponding to the selected bundled note distribution scheme;

and step S124, determining at least one type of money distribution result according to the selected bundled money distribution scheme and the selected loose money distribution scheme.

Specifically, when dispensing money to the withdrawal amount unit M of the user, first, a dispensing mantissa w is determined, and the bundled money is dispensed according to the dispensing mantissa w, where: w is B₁y₁+B₂y₂+...+B_my_mTherefore, if the total amount of the bundled banknotes is S, the following are provided: m-w ═ S ═ A₁x₁+A₂x₂+...+A_nx_n. Thus, x is determined from the dispense mantissa w₁，x_2,，…，x_nThe value of (2) can determine the money distribution scheme of the bundled money. Then according to the determined cash-dispensing mantissa w, the formula w is equal to B₁y₁+B₂y₂+...+B_my_mDetermination of y₁，y_2,，…，y_mAnd further determining the loose note distribution scheme.

For a specific dispensing mantissa w, the equation w is B₁y₁+B₂y₂+...+B_my_mThere may be multiple sets of solutions, i.e. each determined dispensing mantissa w corresponds to at least one dispensing scheme; in the case of a banknote-dispensing mantissa determination, S and a are used for the equation M-w₁x₁+A₂x₂+...+A_nx_nThere may also be at least one set of solutions; therefore, one of the obtained bundled-banknote distribution schemes and one of the obtained scattered-banknote distribution schemes are respectively selected according to the determined banknote distribution mantissas, so that a banknote distribution result matched with the money amount withdrawn by the user can be formed, and at least one banknote distribution result is formed.

As shown in fig. 3, preferably, the distributing of the whole bundle of dispensed banknotes according to the user money amount and the bundle banknote information to obtain a bundle banknote distribution scheme and a banknote distribution mantissa specifically includes:

step S1211, determining the maximum common divisor of the single bundle amount of each bundle of money according to the bundle of money information;

step S1212, determining the currency-dispensing mantissa according to the user money-withdrawing amount, so that the difference between the user money-withdrawing amount and the currency-dispensing mantissa can be divided exactly by the maximum common divisor of the single bundle of currency of the bundle of currency; the currency distribution mantissa satisfies: the currency distribution mantissa is not less than 0 and not more than the withdrawal amount of the user;

and step S1213, determining at least one bundled note dispensing scheme according to the dispensing mantissa.

Specifically, when determining the money distribution scheme of the bundled money, the equation M-w is determined to be S-A₁x₁+A₂x₂+...+A_nx_nThe integer solution of (a). At this time, the single bundle amount A of each bundle note is first determined₁，A_2,，…，A_nThe greatest common divisor (gcd) of (1), is denoted as gcd (A)₁，A_2,，…，A_n) (ii) a Determining a dispensing mantissa w such that (M-w) satisfies: 0-w-M, and can be gcd (A)₁，A_2,，…，A_n) Trimming; obtaining an equation M-w-S-A according to the determined cash-dispensing mantissa w₁x₁+A₂x₂+...+A_nx_nThe integer solution of (2). Otherwise, if S cannot be gcd (A)₁，A_2,，…，A_n) When the paper money is completely removed, the paper money is bound under the current paper money distribution mantissa wAnd (5) if the paper money distribution fails, bundling and distributing the paper money after the paper money distribution mantissa w is adjusted.

And then obtaining the solution of the equation after conversion. If 1170 is 6x +10y +15z, 1170 may be converted to 6(x + y +2z) +4y +3z, 1170 is x + y +2z, 1170 is 6u +4y +3z, where the coefficients 4 for y and 3 for z are relatively prime. And (4) solving according to the method.

The following describes the solution process of the above equation (1) with reference to specific examples:

suppose that the financial terminal has four bundles of banknotes, and the money amount of each bundle of banknotes is 100 yuan, 50 yuan, 20 yuan and 15 yuan, namely A₁＝100，A₂＝50，A₃＝20，A₄15. The remaining available banknote bundle numbers are: x₁＝15,X₂＝10,X₃＝18,X₄20. If the user's money transfer amount is 156 Yuan 5, the maximum common divisor of 100,50,20, 15 is 5, 1565% gcd (100,50,20,5) ═ 0 according to 100x₁+50x₂+20x₃+15x₄1565 on both sides, and 20 ×, obtained₁+10x₂+4x₃+3x₄313 since x₃、x₄Coprime, so the equation becomes a one-dimensional equation: 4x₃+3x₄＝313-20x₁-10x₂FromAt 4x₃+3x₄The general solution for 1 is:

then 4x₃+3x₄＝313-20x₁-10x₂The general solution of (A) is as follows:

namely, it is

As shown in fig. 4, preferably, the allocating the single-sheet output banknotes according to the banknote allocation mantissa and the loose banknote information, and determining the loose banknote allocation scheme specifically include:

step S1221, determining the largest common divisor of the cash distribution mantissa and the cash dispensing denomination according to the cash dispensing information;

step S1222, determining at least one loose banknote dispensing scheme according to at least one loose banknote dispensing rule and combining the dispensing mantissa and the greatest common divisor of the loose banknote denomination.

Specifically, after the bundled note distribution scheme is obtained, loose notes are distributed according to the determined note distribution mantissa w. By w ═ B₁y₁+B₂y₂+...+B_my_mIt can be seen that when dispensing loose banknotes, w, B are determined₁,B₂,…B_mThen according to the solving method of equation (1), the equation w is equal to B₁y₁+B₂y₂+...+B_my_mThe integral solution of the above steps can obtain the loose banknote distribution scheme.

Optionally, when dispensing the banknotes according to the money amount of the user, the single bundle amount of each bundle of banknotes can be regarded as the denomination of the loose banknotes, for example, the bundle of banknotes formed by 10 banknotes with 100 dollar size can be regarded as a loose banknote with 1000 dollar denomination, and then the loose banknote and the bundled banknote are dispensed together; the method comprises the following steps: the withdrawal amount of the user meets the following requirements: m ═ a₁x₁+A₂x₂+...+A_nx_n)+(B₁y₁+B₂y₂+...+B_my_m) The banknote can be distributed according to the following four banknote distribution principles:

1) the maximum total number of bound paper money is determined

As large as possible, i.e. by

2) The principle of maximum total money amount of money binding is adopted, at the moment

As large as possible, i.e. by

3) The minimum total number of loose banknotes, at this time

As small as possible, i.e. it is desired to

4) The principle of minimum total amount of loose money, namely the principle of minimum number of tails of money distribution, is adopted, at the moment

As small as possible, i.e. it is desired to

The following description is made in conjunction with a specific user withdrawal example:

suppose that the financial terminal equipment is equipped with two bundles of banknotes, namely 15 bundles of 1 ten thousand yuan, 10 bundles of 1.5 ten thousand yuan, 12 of 50 yuan and 10 of 20 yuan, namely A₁＝10000,A₂＝15000,X₁＝15,X₂＝10，B₁＝50,B₂＝20,Y₁＝12,Y₂＝10。

If the user inputs 35550 yuan, 35550 yuan first<(10000 × 15+15000 × 10+50 × 12+20 × 10), and further the following is calculated for the dispensed banknote: 10000x₁+15000x₂+50y₁+20y₂10000x for M₁+15000x₂＝M-50y₁-20y₂Since S is not more than 35550 and the number divisible by 5000 is 35000, gcd (10000,15000) is 5000, and S is 35000, 10000x is calculated₁+15000x₂35000, 2x₁+3x₂If 7, the process is verified and converted

Can obtain x₁＝-7+3t,x₂7-2t, x is smaller than or equal to 0₁≤15,0≤x₂Less than or equal to 10, can be obtained

t is an integer, t is 3, and x is obtained₁＝2,x₂1. At this time, 50y₁+20y₂550, get 5y₁+2y₂55, matrix conversion

Can obtain y₁＝55+2t,y₂-110-5t, since 0 ≦ y₁≤12,0≤y₂T is not less than 10, and the value range of t is not less than-24 and not more than-22.

Preferably, the loose banknotes are dispensed in five manners, i.e., an average dispensing manner, an average emptying manner, a minimum total number method, a maximum denomination priority manner, and a minimum denomination priority manner.

If the method is an average cash dispensing method, y is₁≈y₂I.e. by

Where σ is as small as possible. And because-168 is less than or equal to 7t is less than or equal to-154. So that t-24, σ -3, y₁＝7,y₂The scheme of dispensing the requested loose banknotes is 10.

If it is a null method, there is y₁-y₂12-10+ σ ≈ 2+ σ, where | σ | is as small as possible, i.e. 163+7t ≦ σ, and-24 ≦ t ≦ -22, so t ≦ -23, σ ≦ 2, y ≦ 22₁＝9,y₂5 is the scheme of dispensing the requested loose banknotes.

If the total number of sheets is the minimum, there is (y)₁+y₂) As small as possible (-55-3t) as small as possible, and-24. ltoreq. t.ltoreq.22, to give t-22, y₁＝11,y₂The scheme of dispensing the required loose banknotes is 0.

If it is the maximum denomination priority method, there is y₁As large as possible, 55+2t is as large as possible, and-24. ltoreq. t.ltoreq.22, to give t-22, y₁＝11,y₂The scheme of dispensing the required loose banknotes is 0.

If the method is the minimum denomination priority method, y is₂As large as possible, then-110-5 t is as large as possible, and-24. ltoreq. t.ltoreq.22, to give t-24, y₁＝7,y₂The scheme of dispensing the requested loose banknotes is 10.

For another example: when the withdrawal amount of the user is 135550 yuan, firstly, the withdrawal amount is judged: 135550<(10000x15+15000x10+50x12+20x10), when the withdrawal amount is less than the total amount held by the financial terminal, the bank note is dispensed: 10000x₁+15000x₂+50y₁+20y₂10000x for M₁+15000x₂＝M-50y₁-20y₂S. Wherein gcd (10000,15000) is 5000, and since it is not more than 135550 and is 135000 which can be evenly divided by 5000, and m is 135000, 10000x is calculated₁+15000x₂135000, 2 ×₁+3x₂27. Matrix conversion of equations

Can obtain x₁＝-27+3t,x₂27-2t, since x is more than or equal to 0 ≦ x₁≤15,0≤x₂T is not more than 10, t is not less than 9 and not more than 13, t is an integer, t is 9, 10, 11, 12 and 13, and a plurality of solutions can be obtained: t is 9, x₁＝0,x₂＝9、t＝10,x₁＝3,x₂＝7、t＝11,x₁＝6,x₂＝5、t＝12,x₁＝9,x₂＝3、t＝13,x₁＝12,x₂1. The method is the same as the method when loose banknotes are dispensed, and the details are not repeated.

And step S13, calling the money distribution result, and respectively carrying out the money outlet of the bundled money and the money outlet of the scattered money.

Preferably, the calling the money distribution result to respectively perform the money discharging of the bundled money and the money discharging of the loose money comprises:

calling the bank note distribution result with the minimum bank note output tail number, and respectively carrying out bank note output of bundled bank notes and bank note output of scattered bank notes;

or calling the money distribution result according to the selection of the user, and respectively carrying out the money outlet of the bundled money and the money outlet of the scattered money.

Specifically, after the money is distributed according to the money drawing amount of the user to obtain the money distribution result, when the user does not select, the money is discharged according to the money distribution result selected by default at the financial terminal, namely, the money is discharged according to the scheme that the money distribution mantissa w is minimum, namely, the money bundling and money discharging amount is maximum. In addition, the money can be discharged according to the selection of the user. For example, the user may select the most currency bundles to be dispensed or the least total number of loose currency.

Preferably, before the calculating the money distribution according to the money drawing amount of the user, the money bundling information and the money scattering information to obtain a money distribution result, the method further comprises:

determining the maximum common divisor of the single bundle amount and the loose note denomination of the bundled notes;

judging whether the withdrawal amount of the user can be divided by the maximum common divisor of the single bundle amount of the bundled banknotes and the loose banknote denomination;

and returning a money distribution failure result when the money withdrawal amount of the user cannot be divided by the maximum common divisor of the single bundle amount of the bundled money and the loose money denomination.

Specifically, after receiving a withdrawal amount inputted by a user, firstly, the withdrawal amount is judged: if the money drawing amount of the user cannot be divided by the maximum common divisor of the single bundle amount of the bundled money and the loose money denomination, the money drawing amount required by the user cannot be given by the current financial terminal, and the money drawing failure occurs.

For example: suppose that the financial terminal is equipped with two bundles of banknotes, 1 ten thousand dollars in a bundle of 15 bundles (i.e., a bundle of 1 ten thousand dollars in amount of banknotes has 15 bundles), 1.5 ten thousand dollars in a bundle of 10 bundles, and another two bundles of 12 banknotes with a denomination of 50 dollars and 10 banknotes with a denomination of 20 dollars, i.e., a₁＝10000,A₂＝15000,X₁＝15,X₂＝10，B₁＝50,B₂＝20,Y₁＝12,Y₂＝10。

If the withdrawal amount of the user is 35545 yuan, the money allocation fails because the greatest common divisor of (10000,15000,50,20) is 10, 35545% gcd (50,20) is 5 ≠ 0;

or the money drawing amount of the user is 135545 yuan, since the greatest common divisor of (10000,15000,50,20) is 10, 135545% gcd (50,20) is 5 ≠ 0, and the money dispensing fails because the current financial terminal cannot give the money amount to the user.

In the first embodiment of the invention, money distribution is carried out on the money drawing amount of a user according to the obtained money binding information and money scattering information of the current financial terminal, a money distribution result is obtained, the money distribution of the money binding and the money scattering are respectively carried out during the money distribution, at least one money distribution result is obtained, then money is discharged according to the selected money distribution result, the money amount of a single bundle of money can be very large when the whole bundle of money is discharged, the requirement of large-amount money discharge is met, the money discharging time is shortened, and the fault probability during the money discharge is reduced; the single loose note can be used for counting the number of the dispensed notes required by the user, so that the range of the money dispensing amount of the user is increased; in addition, in the embodiment, when the banknote-out calculation is carried out, the banknote-bundling banknote-out result and the banknote-scattering banknote-out result are combined for calculation, so that the banknote-bundling banknote-out result is as large as possible, the banknote-scattering banknote-out result is as small as possible, and the banknote-out time is further shortened; and because various money distribution results are obtained in the money distribution process, the user can select the money outlet result according to the requirement, and the user experience is improved.

It should be understood that, in the embodiment of the present invention, the sequence numbers of the above-mentioned processes do not mean the 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 embodiment of the present invention.

The following description is made in conjunction with a specific user withdrawal example:

suppose that the financial terminal device is equipped withTwo kinds of bundled banknotes, 1 ten thousand yuan one bundle is 15 bundles, 1.5 ten thousand yuan one bundle is 10 bundles, and the other two kinds of bundled banknotes can be scattered, and the denomination of the bundled banknotes is 50 yuan 12 and the denomination of the bundled banknotes is 20 yuan 10, namely A₁＝10000,A₂＝15000,X₁＝15,X₂＝10，B₁＝50,B₂＝20,Y₁＝12,Y₂＝10。

If the user inputs 35550 yuan, 35550 yuan first<(10000 × 15+15000 × 10+50 × 12+20 × 10), and further the following is calculated for the dispensed banknote: 10000x₁+15000x₂+50y₁+20y₂10000x for M₁+15000x₂＝M-50y₁-20y₂Since S is not more than 35550 and the number divisible by 5000 is 35000, gcd (10000,15000) is 5000, and S is 35000, 10000x is calculated₁+15000x₂35000, 2x₁+3x₂If 7, the process is verified and converted

If it is a null method, there is y₁-y₂12-10+ σ ≈ 2+ σ, where | σ | is as small as possible, i.e. 163+7t ≦ σ, and-24 ≦ t ≦ -22, so t ≦ -23, σ ≦ 2, y ≦ 22₁＝9,y₂5 is the scheme of dispensing the requested loose banknotes.

If the total number of sheets is the minimum, there is (y)₁+y₂) As small as possible (-55-3t) as small as possible, and-24. ltoreq. t.ltoreq.22, to give t-22, y₁＝11,y₂The scheme of dispensing the required loose banknotes is 0.

If it is the maximum denomination priority method, there is y₁As large as possible, 55+2t is as large as possible, and-24. ltoreq. t.ltoreq.22, to give t-22, y₁＝11,y₂The scheme of dispensing the required loose banknotes is 0.

For another example: when the withdrawal amount of the user is 135550 yuan, firstly, the withdrawal amount is judged: 135550<(10000x15+15000x10+50x12+20x10), when the withdrawal amount is less than the total amount held by the financial terminal, the bank note is dispensed: 10000x₁+15000x₂+50y₁+20y₂10000x for M₁+15000x₂＝M-50y₁-20y₂S. Wherein gcd (10000,15000) is 5000, and since it is not more than 135550 and is 135000 which can be evenly divided by 5000, and m is 135000, 10000x is calculated₁+15000x₂135000, 2 ×₁+3x₂27. Matrix conversion of equations

Can obtain x₁＝-27+3t,x₂27-2t, since x is more than or equal to 0 ≦ x₁≤15,0≤x₂T is not less than 10, t is not less than 9 and not more than 13, t is an integer, can be obtainedTaking t as 9, 10, 11, 12, 13, multiple sets of solutions can be obtained: t is 9, x₁＝0,x₂＝9、t＝10,x₁＝3,x₂＝7、t＝11,x₁＝6,x₂＝5、t＝12,x₁＝9,x₂＝3、t＝13,x₁＝12,x₂1. The method is the same as the method when loose banknotes are dispensed, and the details are not repeated.

and the second cash-out module is used for respectively carrying out cash-out of the bound cash and cash-out of the scattered cash according to the cash-distribution result selected and called by the user.

Specifically, after the money is distributed according to the money drawing amount of the user to obtain the money distribution result, when the user does not select, the money is discharged according to the money distribution result selected by default at the financial terminal, namely, the money is discharged according to the scheme that the money distribution mantissa w is minimum, namely, the money bundling and money discharging amount is maximum. In addition, the money can be discharged according to the selection of the user. For example, the user may select the most currency bundles to be dispensed or the least total number of loose currency.

Specifically, after receiving a withdrawal amount inputted by a user, firstly, the withdrawal amount is judged: if the money drawing amount of the user cannot be divided by the maximum common divisor of the single bundle amount of the bundled money and the loose money denomination, the money drawing amount required by the user cannot be given by the current financial terminal, and the money drawing failure occurs.

For example: suppose that the financial terminal is equipped with two bundles of banknotes, 1 ten thousand dollars in a bundle of 15 bundles (i.e., a bundle of 1 ten thousand dollars in amount of banknotes has 15 bundles), 1.5 ten thousand dollars in a bundle of 10 bundles, and another two bundles of 12 banknotes with a denomination of 50 dollars and 10 banknotes with a denomination of 20 dollars, i.e., a₁＝10000,A₂＝15000,X₁＝15,X₂＝10，B₁＝50,B₂＝20,Y₁＝12,Y₂＝10。

If the withdrawal amount of the user is 35545 yuan, the money allocation fails because the greatest common divisor of (10000,15000,50,20) is 10, 35545% gcd (50,20) is 5 ≠ 0;

or the money drawing amount of the user is 135545 yuan, since the greatest common divisor of (10000,15000,50,20) is 10, 135545% gcd (50,20) is 5 ≠ 0, and the money dispensing fails because the current financial terminal cannot give the money amount to the user.

Preferably, the output device is specifically configured to:

calling the bank note distribution result with the minimum bank note output tail number, and respectively carrying out bank note output of bundled bank notes and bank note output of scattered bank notes;

or the bank note distribution result is called according to the selection of the user, and the bank note bundling and the bank note scattering are respectively carried out.

Specifically, after the money is distributed according to the money drawing amount of the user to obtain the money distribution result, when the user does not select, the money is discharged according to the money distribution result selected by default at the financial terminal, namely, the money is discharged according to the scheme that the money distribution mantissa w is minimum, namely, the money bundling and money discharging amount is maximum. In addition, the money can be discharged according to the selection of the user. For example, the user may select the most currency bundles to be dispensed or the least total number of loose currency.

Preferably, the processor is further configured to:

determining the maximum common divisor of the single bundle amount and the loose note denomination of the bundled notes; judging whether the withdrawal amount of the user can be divided by the maximum common divisor of the single bundle amount of the bundled banknotes and the loose banknote denomination; correspondingly, the output equipment is also used for returning a money distribution failure result when the money drawing amount of the user cannot be divided by the maximum common divisor of the single bundle amount of the bundled money and the loose money denomination.

Specifically, after receiving a withdrawal amount inputted by a user, firstly, the withdrawal amount is judged: if the money drawing amount of the user cannot be divided by the maximum common divisor of the single bundle amount of the bundled money and the loose money denomination, the money drawing amount required by the user cannot be given by the current financial terminal, and the money drawing failure occurs.

For example: suppose that the financial terminal is equipped with two bundles of banknotes, 1 ten thousand dollars in a bundle of 15 bundles (i.e., a bundle of 1 ten thousand dollars in amount of banknotes has 15 bundles), 1.5 ten thousand dollars in a bundle of 10 bundles, and another two bundles of 12 banknotes with a denomination of 50 dollars and 10 banknotes with a denomination of 20 dollars, i.e., a₁＝10000,A₂＝15000,X₁＝15,X₂＝10，B₁＝50,B₂＝20,Y₁＝12,Y₂＝10。

If the withdrawal amount of the user is 35545 yuan, the money allocation fails because the greatest common divisor of (10000,15000,50,20) is 10, 35545% gcd (50,20) is 5 ≠ 0.

In the third embodiment of the invention, the input equipment acquires the money binding information and the money scattering information of the current financial terminal, the processor distributes money to the money drawing amount of a user and obtains a money distribution result, the money distribution of the bound money and the money scattering information are respectively carried out during the money distribution to obtain at least one money distribution result, then the output equipment delivers the money according to the selected money distribution result, the money amount of a single bundle of money can be very large during the whole bundle of money delivery, the requirement of large-amount money delivery is met, the money delivery time is shortened, and the fault probability during the money delivery is reduced; the loose bank note can be dispensed with the amount of bank notes required by the user, so that the range of the bank note dispensing amount of the user is increased; in addition, in the embodiment, when the banknote-out calculation is carried out, the banknote-bundling banknote-out result and the banknote-scattering banknote-out result are combined for calculation, so that the banknote-bundling banknote-out result is as large as possible, the banknote-scattering banknote-out result is as small as possible, and the banknote-out time is further shortened; and because various money distribution results are obtained in the money distribution process, the user can select the money outlet result according to the requirement, and the user experience is improved.
