Description

Banknote control method, system and financial terminal for financial terminal Technical field

The embodiment of the invention belongs to the technical field of financial equipment, and particularly relates to a method, system and financial terminal for controlling the cash out of a financial terminal.

Background technique

With the application and development of computer technology and communication technology in the financial industry, people rely more and more on financial self-service terminals (such as automatic teller machines (ATMs)). At present, financial self-service terminals, when cashing out, mostly digging out one by one from the cash box, then selecting and identifying, the qualified banknotes are stacked in the temporary storage device, and the unqualified banknotes are recycled to the waste cash box. Generally referred to as counting money, the number of banknotes required for this business is counted, and then the banknotes stacked on the temporary storage device are sent to the cash dispensing port for the user to take. At present, the banknote counting performance is generally 8 per second. If it is a large withdrawal, the time for counting money will be longer, and the time for recycling may be incurred. If the banknotes of the banknotes are of poor quality, the banknote recovery rate is high. The counting time is longer. Generally speaking, it takes at least a minute to issue 500 high-quality banknotes. If the quality of the banknotes is low, it may take more than two minutes or more, and sometimes even a banknote accident occurs. Since the amount of money to be dispensed when a large amount of money is issued is several times or even several times that of the usual withdrawal business, the probability of the movement of the movement is several times and several times or more of the general withdrawal business, and the actual working time. The utilization rate of the movement is not high. At the same time, when the amount is large, the number of banknotes is large, and the time for issuing the banknotes is also large. The increase of the banknote failure rate leads to the double growth of the Chongzheng business, to the banking system and the network. Brought a lot of unnecessary overhead.

detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

After receiving the user withdrawal information, the financial terminal first acquires the withdrawal amount of the user, all the banknote information of the current financial terminal and the banknote information; and allocates the banknotes according to the banknote information and the banknote information, and then calls As a result of the banknote dispensing, the banknotes of the banknotes and the banknotes of the banknotes can be separately dispensed according to the results of the banknotes. Therefore, when the user makes a large withdrawal, the combination of the whole bundle of banknotes and the loose banknotes is adopted. The amount of banknotes is generally large, and the whole bundle of banknotes shortens the time for issuing notes and reduces the probability of banknote failure.

In order to explain the technical solution described in the present invention, the following description will be made by way of specific embodiments.

Embodiment 1:

FIG. 1 is a flow chart showing a method for controlling a cash withdrawal of a financial terminal according to a first embodiment of the present invention, which is described in detail as follows:

At present, financial terminal equipment can only carry out banknotes and banknotes when performing user deposit tasks. For example, the cycle machine and cash machine that are put into operation on the market need to check and verify the banknotes one by one, and then hand it over to the banknotes. user. This is very suitable for small-volume cash-out occasions. For large-value banknotes, especially for one-time banknotes, the banknotes of banknotes are prone to accidents such as banknotes, resulting in transaction failure; in this case, business rollback processing The process is cumbersome and complicated, especially in the case that the user has already received a part of the banknotes, and the banknotes are abnormal, resulting in the failure of the banknotes to meet the withdrawal amount. Due to the large amount involved, it is easy to bring dissatisfaction to the bank's big customers and provide excellent services to the bank. The damage is also great. Therefore, in order to make up for the shortcomings of the banknotes in the form of a large amount of money, the financial terminal of the present invention firstly:

Step S11, obtaining a user withdrawal amount, a bundle information of the current financial terminal, and a banknote information;

In this step, the current user's withdrawal amount M is obtained, and at the same time, the current financial terminal's bundle information and the banknote information are obtained. The bundled banknote refers to putting a plurality of banknotes of the same denomination together to form a bundle and storing it in a financial device. For example, 20 banknotes with a denomination of 100 yuan are bundled into one bundle, or 50 banknotes with a denomination of 20 yuan are bundled into a bundle. The setting of each bundle of banknotes can also be set as needed. A banknote is a single banknote of various denominations, such as a banknote with a denomination of 50 yuan. The bundle information includes: a bundle type n, a bundle amount A ₁ , A _{2 ,} , ..., A _n of each bundle and the number of available bundles of each bundle X ₁ , X _2, , ... , X _n , X∈Z; the banknote information includes: the type of the banknote m, the denominations B ₁ , B _2, , ..., B _m of each banknote and the amount of the banknotes Y ₁ , Y _{2 for} each denomination _, ,...,Y _m ,Y∈Z.

Step S12, performing banknote calculation according to the user withdrawal amount, banknote information and banknote information, and obtaining a banknote dispensing result;

According to the user withdrawal amount M, and the current financial terminal's banknotes and banknotes information, the banknotes are dispensed; the current user withdrawal amount M is required for each banknote to be x ₁ , x ₂ , ..., x _n, x∈Z; the number of required notes is y ₁ , y _2, , ..., y _m , y ∈ Z; where 0 ≤ x ₁ ≤ X ₁ , 0 ≤ x _2, ≤ X _2, ,..., 0 ≤ x _n ≤ X _n ; 0 ≤ y ₁ ≤ Y ₁ , 0 ≤ y _2, ≤ Y _2, , ..., 0 ≤ y _m ≤ Y _m . Then there are: M = A ₁ x ₁ + A ₂ x ₂ + ... + A _n x _n + B ₁ y ₁ + B ₂ y ₂ + ... + B _m y _m .

As shown in FIG. 2, preferably, the banknote calculation is performed according to the user withdrawal amount, the banknote information, and the banknote information, and the banknote distribution result is obtained, which specifically includes:

Step S121, according to the user withdrawal amount and the bundle information, the banknotes of the bundles are dispensed, and the banknote distribution scheme and the banknotes are obtained;

Step S122, performing a banknote dispensing of a single banknote according to the tailnote number and the banknote information, and determining a banknote dispensing scheme;

Step S123, selecting one of the banknote dispensing schemes, and selecting one of the banknote dispensing schemes according to the banknote ending number corresponding to the selected banknote dispensing scheme;

Step S124, determining at least one of the banknote dispensing results according to the selected banknote dispensing scheme and the selected banknote dispensing scheme.

Specifically, when the user's withdrawal amount M is dispensed, the banknotes w is first determined, and the banknotes are bundled according to the banknotes w, at which time: w=B ₁ y ₁ +B ₂ y ₂ +...+B _m y _m , therefore, if the total amount of the banknotes is S, then: Mw=S=A ₁ x ₁ +A ₂ x ₂ +...+A _n x _n . Therefore, the value of x ₁ , x _2, , ..., x _n is determined according to the tail number w of the banknote _, and the banknote dispensing scheme of the banknote can be determined. Then, according to the determined banknote mantissa w, the value of y ₁ , y _2, , ..., y _m is determined by the formula w=B ₁ y ₁ +B ₂ y ₂ +...+B _m y _{m to} determine the banknote The banknote scheme.

For a certain banknote mantissa w, the equation w=B ₁ y ₁ +B ₂ y ₂ +...+B _m y _m can have multiple sets of solutions, ie each determined banknote tail w corresponds to at least one match Banknote scheme; and in the case where the banknote mantissa is determined, there may be at least one set of solutions for the equation Mw=S=A ₁ x ₁ +A ₂ x ₂ +...+A _n x _n ; The banknotes respectively select one of the obtained banknote dispensing schemes and one of the banknote dispensing schemes, and can form a banknote matching result matching the user withdrawal amount, and the banknote dispensing result has at least one.

As shown in FIG. 3, preferably, the banknotes are dispensed according to the user withdrawal amount and the bundle information, and the banknote dispensing scheme and the banknote tailing number are obtained, which specifically includes:

Step S1211, determining the greatest common divisor of the single bundle amount of each bundle of banknotes according to the bundle information;

Step S1212, determining a banknote ending number according to the user withdrawal amount, so that the difference between the user withdrawal amount and the banknote ending number is divisible by the greatest common divisor of the bundled banknote amount; Satisfaction: 0 ≤ banknote tail number ≤ user withdrawal amount;

Step S1213, determining at least one type of banknote dispensing scheme according to the banknote ending number.

Specifically, in determining the banknote dispensing scheme, it is sufficient to determine an integer solution of the equation Mw=S=A ₁ x ₁ +A ₂ x ₂ +...+A _n x _n . At this time, first determine the maximum common divisor (gcd) of the single bundle amount A ₁ , A _2, , ..., A _n of each bundle, and record it as gcd (A ₁ , A _2, ,..., A _n ); determine a banknote mantissa w such that (Mw) satisfies: 0 ≤ (Mw) ≤ M, and can be divisible by gcd (A ₁ , A _2, , ..., A _n ); according to the determined banknote tail number w An integer solution of the equation Mw = S = A ₁ x ₁ + A ₂ x ₂ + ... + A _n x _n is obtained. In addition, if S cannot be divisible by gcd (A ₁ , A _2, , ..., A _n ), the current banknotes w, the banknotes fail to be dispensed, and the banknotes are adjusted w, and then the banknotes are dispensed.

The solution process of the integer solution of S = A ₁ x ₁ + A ₂ x ₂ + ... + A _n x _n is described in detail below.

For the equation: S=A ₁ x ₁ +A ₂ x ₂ +...+A _n x _n (1)

If the n-ary integer coefficient indefinite equation S=A ₁ x ₁ +A ₂ x ₂ +...+A _n x _n , satisfying gcd(A ₁ ,A _2, ,...,A _n ) is greater than 1, the equation will be Divide gcd(A ₁ , A _2, ,..., A _n ) on both sides to obtain an n-ary integer coefficient indefinite equation s=a ₁ x ₁ +a ₂ x ₂ +...+a _n x _n , where gcd(a ₁ , a _2, ,..., a _n )=1.

For the n-ary integer coefficient indefinite equation s=a ₁ x ₁ +a ₂ x ₂ +...+a _n x _n , it is judged whether there are two primes in a ₁ , a _{2 ,} , ..., a _n The coefficient, if any, may be set such that its two prime coefficients are (a ₁ , a _2, ), then the equation s=a ₁ x ₁ +a ₂ x ₂ +...+a _n x _{n is} converted to a ₁ x ₁ + a ₂ x ₂ = s - (a ₃ x ₃ + ... + a _n x _n ). Let a special solution of a ₁ x ₁ + a ₂ x ₂ =1 be (x ₀₁ , x ₀₂ ) (the equation a ₁ x ₁ + a ₂ x ₂ =1 refers to the following method to find a special solution), then s = a The general solution of ₁ x ₁ + a ₂ x ₂ +...+a _n x _n is:

Where t, x ₃ -, x ₄ , ..., x _n ∈Z, according to the value range of t combined with the user withdrawal amount, a banknote arrangement scheme of multiple sets of banknotes can be obtained.

A solution method for the equation a ₁ X ₁ +a ₂ X ₂ =m

The formula is as follows: the binary one-time integral coefficient indefinite equation a ₁ X ₁ +a ₂ X ₂ =m, where the general solution of gcd(a ₁ , a ₂ )=1 is X ₁ =X ₀₁ +a ₂ t, X ₂ =X ₀₂ -a ₁ t where t is a free variable taking an integer, X ₀₁ and X ₀₂ are a ₁ X ₁ +a ₂ X ₂ =m a special solution, and the binary indefinite equation a ₁ X ₁ +a ₂ X ₂ The essence of a special solution of =m is to find the integer x ₁₀ , x _{20 such} that the linear combination of a and b satisfies a ₁ x ₁₀ + a ₂ x ₂₀ = m.

You can use the elementary row transformation of the matrix. The following is the solution to its special solution:

1) Establish a matrix

2) Pair matrix

Perform the elementary row transformation of the matrix, and the row elementary transformation method is:

2a) Multiply a row element of the matrix by a non-zero integer to get a new row;

2b) Multiply a row element of the matrix by the integer k(k≠0) to add to the corresponding element of another row of the matrix to get a new row.

3) Make the matrix

After the transformation of the line, etc.

Where (r|m).

One of the methods of linear combination is to use the enthalpy division method to take the remainder method: since a ₁ and a ₂ are relatively prime, the remainder of the enthalpy division is not zero. Let a ₁ > a ₂ , then a ₁ can be expressed as a ₁ =k ₁ a ₂ +r ₁ (r ₁ <a ₂ ). If r ₁ ≠1, a ₂ can be expressed as a ₂ =k ₂ r ₁ +r ₂ (r ₂ <r ₁ ), if r ₂ ≠1 continues until r _i =1. Such as

4) can get a ₁ X ₁ + a ₂ X ₂ = m a special solution for

5) will

Substituting X ₁ =X ₀₁ +a ₂ t, X ₂ =X ₀₂ -a ₁ t,

The following illustrates the solution process with an example: 5X ₁ + 2X ₂ = m for proof conversion, there is

Can get X ₁₀ =m+2t, X ₂₀ =-2m-5t

If the n-ary integer coefficient indefinite equation s=a ₁ x ₁ +a ₂ x ₂ +...+a _n x _n , there are no two primes in (a ₁ , a _2, ,..., a _n ) The coefficient, since a ₁ , a ₂ , ···, the absolute value of a _n is greater than 1, calling a coefficient with the smallest absolute value, set a ₁ , a ₁ >0, then other books can be expressed as: a _i =k _i a ₁ +r _i ,0≤r _i <a ₁ (i=2,3,···,n). At this time, the original equation can be transformed into: a ₁ (x ₁ +k ₂ x ₂ +· ··+k _n x _n )+r ₂ x ₂ +r ₃ x ₃ +···+r _n x _n =S. If a ₁ , r ₂ , r ₃ , ···, r _n For each of the matrices, the equation a ₁ (x ₁ is obtained according to the method described above in s=a ₁ *x ₁ +a ₂ *x ₂ +...+a _n *x _n ,(a ₁ ,a ₂ ). +k ₂ x ₂ +···+k _n x _n )+r ₂ x ₂ +r ₃ x ₃ +···+r _n x _n =S solution. If any of a ₁ , r ₂ , r ₃ , ···, r _n are not mutually prime, the smallest coefficient is called again, and the other coefficients are represented by the minimum coefficient, and the conversion is performed again until there are two Mutual quality. Then the solution of the transformed equation is obtained. For example, 6x+10y+15z=1170 can be converted into 6(x+y+2z)+4y+3z=1170, so u=x+y+2z, then 6u+4y+3z=1170, where the coefficient 4 of y is The coefficient 3 of z is relatively prime. Solve as described above.

The solution process of the above equation (1) will be described below with reference to specific examples:

Assume that the financial terminal has four kinds of bundles, and the bundle amount of each bundle is 100 yuan, 50 yuan, 20 yuan, 15 yuan, that is, A ₁ =100, A ₂ =50, A ₃ =20, A ₄ =15. The number of remaining banknotes available is: X ₁ = 15, X ₂ = 10, X ₃ = 18, and X ₄ = 20. If the user's withdrawal amount is 156 yuan 5, since the greatest common divisor of 100, 50, 20, 15 is 5,1565% gcd (100, 50, 20, 5) = 0, according to 100x ₁ + 50x ₂ + 20x ₃ + 15x ₄ =1565, divides 5 on both sides, and obtains 20x ₁ +10x ₂ +4x ₃ +3x ₄ =313. Since x ₃ and x _{4 are} mutually prime, the equation becomes a binary one-time equation: 4x ₃ +3x ₄ =313 -20x ₁ -10x ₂ , since the general solution of 4x ₃ +3x ₄ =1 is:

Then the general solution of 4x ₃ +3x ₄ =313-20x ₁ -10x ₂ is:

which is

From 0 ≤ x ₁ ≤ X ₁ , 0 ≤ x ₂ ≤ X ₂ , 0 ≤ x ₃ ≤ X ₃ , 0 ≤ x ₄ ≤ X ₄ and X ₁ = 15, X ₂ = 10, X ₃ = 18, X ₄ = 20 to obtain _{0≤X 1 ≤15,0≤X 2 ≤10,0≤X 3 ≤18,0≤X 4} ≤20, the -87≤313-20x ₁ -10x ₂ ≤313, determining the value t The range is -145 ≤ t ≤ 527.

The value of t has a total of 145+527+1=673, t can take any one of -145, -144, -143....526, 527, and each t value can get a set of x1, x2, x3, x4 values.

As shown in FIG. 4, preferably, according to the tailnote number and the banknote information of the banknote, the banknote dispensing of a single banknote is made, and the banknote dispensing scheme is determined, which specifically includes:

Step S1221, determining the greatest common divisor of the banknote endings and the banknote denomination according to the banknote information;

Step S1222: Determine at least one type of banknote dispensing scheme according to at least one of the banknotes issuing rules, in combination with the maximum common divisor of the banknotes and the banknote denomination.

Specifically, after the banknote dispensing scheme is obtained, the banknotes are dispensed according to the determined number of banknotes w. From w=B ₁ y ₁ +B ₂ y ₂ +...+B _m y _m , it can be seen that when the banknotes are dispensed, the greatest common divisor of w, B ₁ , B ₂ , ... B _{m is} determined, Then, according to the solution method of equation (1), the integral solution of the equation w=B ₁ y ₁ +B ₂ y ₂ +...+B _m y _m is obtained to obtain the banknote dispensing scheme of the banknote.

Alternatively, when the banknotes are dispensed according to the user's withdrawal amount, the bundle amount of each banknote can be regarded as the denomination of the banknotes. For example, a bundle of 10 bundles of 100 dollar bills can be regarded as a bundle. A banknote with a denomination of 1,000 yuan is then dispensed with the banknotes; the method is: the user withdrawal amount is satisfied: M = (A ₁ x ₁ + A ₂ x ₂ +... + A _n x _n ) +(B ₁ y ₁ +B ₂ y ₂ +...+B _m y _m ), can be dispensed according to the following four banknotes:

1), the principle of the maximum number of bundles of bundles, at this time

As large as possible

2), the principle of the maximum amount of banknotes, at this time

As large as possible

3), the principle of the minimum number of loose notes, at this time

As small as possible

4) The principle of the minimum amount of banknotes, that is, the principle of the minimum number of banknotes, at this time

As small as possible

The following is a description of the specific user withdrawal example:

Assume that the financial terminal equipment is equipped with two kinds of banknotes, 15 bundles of 10,000 yuan, 15 bundles of 15,000 yuan, and 10 bundles of 15,000 bundles. There are 12 denominations of 50 yuan for the banknotes. The denomination is There are 10 sheets of 20 yuan, namely A ₁ = 10000, A ₂ = 15000, X ₁ = 15, X ₂ = 10, B ₁ = 50, B ₂ = 20, Y ₁ = 12, and Y ₂ = 10.

If the user input amount is 35550 yuan, first 35550<(10000×15+15000×10+50×12+20×10), further calculate the banknotes: 10000x ₁ +15000x ₂ +50y ₁ +20y ₂ =M, there is 10000x ₁ +15000x ₂ =M-50y ₁ -20y ₂ =S,gcd(10000,15000)=5000, since the number is not more than 35550 and can be divisible by 5000 is 35000, let S=35000, calculate 10000x ₁ +15000x ₂ =35000, get 2x ₁ +3x ₂ =7, proof conversion of the equation

Can obtain x ₁ = -7 + 3t, x ₂ = 7-2t, due to 0 ≤ x ₁ ≤ 15, 0 ≤ x ₂ ≤ 10, available

t is an integer, which can take t=3, and x ₁ =2, x ₂ =1. At this point there is 50y ₁ +20y ₂ =550, get 5y ₁ +2y ₂ =55, matrix conversion

It can be obtained that y ₁ = 55 + 2t, y ₂ = -110 - 5t, and since 0 ≤ y ₁ ≤ 12, 0 ≤ y ₂ ≤ 10, it can be determined that the range of t is -24 ≤ t ≤ -22.

Preferably, the method of dispensing money of the banknotes can be divided into five types: an average billing method, a moving average method, a total number of sheets minimum method, a maximum denomination priority method, and a minimum denomination priority method.

If it is the average billing method, there is y ₁ ≈ y ₂ , that is,

Where |σ| is as small as possible. Also because -168 ≤ 7t ≤ -154. So t=-24, σ=-3, y ₁ =7, y ₂ =10 is the banknote dispensing scheme.

If it is a space-time method, there are y ₁ -y ₂ ≈12-10+σ=2+σ, where |σ| is as small as possible, ie 163+7t=σ, and -24≤t≤-22, so t= -23, σ = 2, y ₁ = 9, y ₂ = 5 is the banknote dispensing scheme.

If it is the minimum number of total sheets, if (y ₁ + y ₂ ) is as small as possible, then (-55-3t) is as small as possible, and -24 ≤ t ≤ -22, and t = -22, y ₁ = 11 , y ₂ =0 is the banknote allocation plan for the money.

If it is the maximum denomination priority method, if y _{1 is} as large as possible, then 55+2t is as large as possible, and -24 ≤ t ≤ -22, and t=-22, y ₁ =11, y ₂ =0 is obtained. Banknote dispensing plan.

If it is the minimum denomination priority method, if y _{2 is} as large as possible, then -110-5t is as large as possible, and -24 ≤ t ≤ -22, and t = -24, y ₁ = 7, and y ₂ = 10 is obtained. Banknotes and banknotes.

Another example: when the user withdraws the amount of 135,550 yuan, first determine the withdrawal amount: 135550 < (10000x15 + 5000x10 + 50x12 + 20x10), when the withdrawal amount is less than the total amount held by the financial terminal, the banknote: 10000x ₁ +15000x ₂ +50y ₁ +20y ₂ =M, there are 10000x ₁ +15000x ₂ =M-50y ₁ -20y ₂ =S. Where gcd(10000, 15000)=5000, because the number is not more than 135550 and can be divisible by 5000, the number is 135000, and the other is m=135000, and 10000x ₁ +15000x ₂ =135000 is calculated, and 2x ₁ +3x ₂ =27 is obtained. Matrix transformation of equations

It can be obtained that x ₁ = -27 + 3t, x ₂ = 27-2t, since 0 ≤ x ₁ ≤ 15, 0 ≤ x ₂ ≤ 10, ₉ ≤ t ≤ 13, and t is an integer, and t = 9, 10, 11, 12, 13, can have many sets of solutions: t = 9, x ₁ =0, x ₂ = 9, t = 10, x ₁ = 3, x ₂ = 7, t = 11, x ₁ = 6 , x ₂ = 5, t = 12, x ₁ = 9, x ₂ = 3, t = 13, x ₁ = 12, x ₂ =1. The method of performing banknote dispensing is the same as above, and will not be described here.

In step S13, the banknote dispensing result is invoked, and the banknotes of the banknotes and the banknotes of the banknotes are respectively dispensed.

Preferably, the invoking the banknote dispensing result, respectively, the banknotes of the banknotes and the banknotes of the banknotes, including:

Calling the result of the banknote with the smallest number of banknotes, and the banknotes of the banknotes and the banknotes of the banknotes;

Or, according to the user's choice, the banknote dispensing result is called, and the banknotes of the banknotes and the banknotes of the banknotes are separately dispensed.

Specifically, after the banknote distribution result is obtained according to the user's withdrawal amount, when the user does not make a selection, the banknotes are selected according to the default banknotes selected by the financial terminal, that is, according to the minimum number of banknotes w, that is, the banknotes are bundled. The scheme with the largest amount of banknotes is used for banknotes. In this case, the banknotes can minimize the time for banknotes, save time for financial terminals, and reduce the probability of failure. In addition, it is also possible to dispense money according to the user's choice. For example, the user can select the maximum number of bundles to be dispensed or the total number of sheets of coins to be dispensed.

Preferably, before the calculating the banknotes according to the user withdrawal amount, the banknote information and the banknote information, and obtaining the banknote dispensing result, the method further comprises:

Determine the maximum common denomination of the bundle amount of the bundle and the denomination of the banknote;

Determining whether the amount of withdrawal of the user can be divisible by the maximum common amount of the bundled bundle and the maximum common denomination of the banknote denomination;

When the user withdrawal amount cannot be divisible by the maximum common amount of the bundled bundle and the maximum common denomination of the banknote denomination, the result of the banknote failure is returned.

Specifically, after receiving the withdrawal amount input by the user, first determining the withdrawal amount: if the user withdrawal amount cannot be divisible by the maximum bundle amount of the bundled denomination, the current financial terminal cannot be given The amount of withdrawal required by the user, the payment of the banknote failed.

For example, suppose the financial terminal equipment is equipped with two kinds of bundles, 15 bundles of 10,000 yuan and 15 bundles (that is, 15 bundles of bundles with a value of 10,000 yuan), 10 bundles of 15,000 bundles, and 10 bundles. There are 12 sheets with a denomination of 50 yuan for banknotes and 10 sheets with a denomination of 20 yuan, ie A ₁ =10000, A ₂ =15000, X ₁ =15, X ₂ =10, B ₁ =50 , B ₂ = 20, Y ₁ = 12, and Y ₂ = 10.

If the user withdraws the amount of 35,545 yuan, since the maximum common divisor of (10000, 15000, 50, 20) is 10,35545%gcd(50,20)=5≠0, the banknotes fail;

Or the user withdrawal amount is 135,545 yuan, because the greatest common divisor of (10000, 15000, 50, 20) is 10,135,545%gcd(50,20)=5≠0, and the current financial terminal cannot give the amount stated by the user. The banknote failed.

In the first embodiment of the present invention, the user's withdrawal amount is distributed according to the obtained banknote information and the banknote information of the current financial terminal, and the banknote dispensing result is obtained, and the banknotes and the banknotes are respectively dispensed at the time of dispensing the banknotes. The banknotes of the banknotes yield at least one type of banknotes, and then the banknotes are issued according to the selected banknotes. When the banknotes are bundled, the amount of bundles of bundles can be large, which satisfies the need for large amounts of banknotes. At the same time, shorten the time for issuing notes and reduce the probability of failure when issuing bills; The amount of money that is required by the user is increased, and the range of the amount of money discharged by the user is increased. In addition, in the calculation of the banknotes in this embodiment, the combination of the banknotes and the banknotes are combined to calculate the banknotes, so that the banknotes can be bundled. The result of the banknote is as large as possible, the banknotes are as small as possible, and the time for banknotes is further shortened; and because of the multiple banknotes obtained during the banknote dispensing process, the user can also select the banknotes as needed to improve the user. Experience.

It should be understood that, in the embodiment of the present invention, the size of the sequence numbers of the foregoing processes does not mean the order of execution sequence, and the execution order of each process should be determined by its function and internal logic, and should not be implemented in the embodiment of the present invention. Form any limit.

Specifically, when the user's withdrawal amount M is dispensed, the banknotes w is first determined, and the banknotes are bundled according to the banknotes w, at which time: w=B ₁ y ₁ +B ₂ y ₂ +...+B _m y _m , therefore, if the total amount of the banknotes is S, then: Mw=S=A ₁ x ₁ +A ₂ x ₂ +...+A _n x _n . Therefore, the value of x ₁ , x _2, , ..., x _n is determined according to the tail number w of the banknote _, and the banknote dispensing scheme of the banknote can be determined. Then, according to the determined banknote mantissa w, the value of y ₁ , y _2, , ..., y _m is determined by the formula w=B ₁ y ₁ +B ₂ y ₂ +...+B _m y _{m to} determine the banknote The banknote scheme.

Specifically, in determining the banknote dispensing scheme, it is sufficient to determine an integer solution of the equation Mw=S=A ₁ x ₁ +A ₂ x ₂ +...+A _n x _n . At this time, first determine the maximum common divisor (gcd) of the single bundle amount A ₁ , A _2, , ..., A _n of each bundle, and record it as gcd (A ₁ , A _2, ,..., A _n ); determine a banknote mantissa w such that (Mw) satisfies: 0 ≤ (Mw) ≤ M, and can be divisible by gcd (A ₁ , A _2, , ..., A _n ); according to the determined banknote tail number w An integer solution of the equation Mw = S = A ₁ x ₁ + A ₂ x ₂ + ... + A _n x _n is obtained. In addition, if S cannot be divisible by gcd(A ₁ , A _2, ,..., A _n ), the current banknotes w, the banknotes fail to be dispensed, and the banknotes w is adjusted, and then the banknotes are dispensed.

For the solution process of the integer solution of S=A ₁ x ₁ +A ₂ x ₂ +...+A _n x _n , refer to the solution process of equation (1), and details are not described herein again. The banknote dispensing scheme is determined based on an integer solution of S = A ₁ x ₁ + A ₂ x ₂ + ... + A _n x _n .

Specifically, after the banknote dispensing scheme is obtained, the banknotes are dispensed according to the determined number of banknotes w. From w=B ₁ y ₁ +B ₂ y ₂ +...+B _m y _m , it can be seen that when the banknotes are dispensed, the greatest common divisor of w, B ₁ , B ₂ , ... B _{m is} determined, Then, according to the solution method of equation (1), the integral solution of the equation w=B ₁ y ₁ +B ₂ y ₂ +...+B _m y _m is obtained to obtain the banknote dispensing scheme of the banknote.

Optionally, when the banknotes are dispensed according to the user's withdrawal amount, the bundle amount of each bundle of bundles can be regarded as the denomination of the banknotes. For example, a bundle of 10 bundles of 100 yuan bills can be regarded as one bundle. A banknote with a face value of 1,000 yuan is then dispensed with the banknotes; the method is: the user withdrawal amount is satisfied: M = (A ₁ x ₁ + A ₂ x ₂ +... + A _n x _n )+(B ₁ y ₁ +B ₂ y ₂ +...+B _m y _m ), can be dispensed according to the following four banknotes:

As large as possible

3), the principle of the minimum number of loose notes, at this time

As small as possible

4) The principle of the minimum amount of banknotes, that is, the principle of the minimum number of banknotes, at this time

As small as possible

The following is a description of the specific user withdrawal example:

Assume that the financial terminal equipment is equipped with two kinds of banknotes, 15 bundles of 10,000 yuan, 15 bundles of 15,000 yuan, and 10 bundles of 15,000 bundles. There are 12 denominations of 50 yuan for the banknotes. The denomination is There are 10 sheets of 20 yuan, namely A ₁ = 10000, A ₂ = 15000, X ₁ = 15, X ₂ = 10, B ₁ = 50, B ₂ = 20, Y ₁ = 12, and Y ₂ = 10.

If the user input amount is 35550 yuan, first 35550<(10000×15+15000×10+50×12+20×10), further calculate the banknotes: 10000x ₁ +15000x ₂ +50y ₁ +20y ₂ =M, there is 10000x ₁ +15000x ₂ =M-50y ₁ -20y ₂ =S,gcd(10000,15000)=5000, since the number is not more than 35550 and can be divisible by 5000 is 35000, let S=35000, calculate 10000x ₁ +15000x ₂ =35000, get 2x ₁ +3x ₂ =7, proof conversion of the equation

Can obtain x ₁ = -7 + 3t, x ₂ = 7-2t, due to 0 ≤ x ₁ ≤ 15, 0 ≤ x ₂ ≤ 10, available

t is an integer, which can take t=3, and x ₁ =2, x ₂ =1. At this point there is 50y ₁ +20y ₂ =550, get 5y ₁ +2y ₂ =55, matrix conversion

It can be obtained that y ₁ = 55 + 2t, y ₂ = -110 - 5t, and since 0 ≤ y ₁ ≤ 12, 0 ≤ y ₂ ≤ 10, it can be determined that the range of t is -24 ≤ t ≤ -22.

Preferably, the method of dispensing money of the banknotes can be divided into five types: an average billing method, a moving average method, a total number of sheets minimum method, a maximum denomination priority method, and a minimum denomination priority method.

If it is the average billing method, there is y ₁ ≈ y ₂ , that is,

Where |σ| is as small as possible. Also because -168 ≤ 7t ≤ -154. So t=-24, σ=-3, y ₁ =7, y ₂ =10 is the banknote dispensing scheme.

If it is a space-time method, there are y ₁ -y ₂ ≈12-10+σ=2+σ, where |σ| is as small as possible, ie 163+7t=σ, and -24≤t≤-22, so t= -23, σ = 2, y ₁ = 9, y ₂ = 5 is the banknote dispensing scheme.

If it is the minimum number of total sheets, if (y ₁ + y ₂ ) is as small as possible, then (-55-3t) is as small as possible, and -24 ≤ t ≤ -22, and t = -22, y ₁ = 11 , y ₂ =0 is the banknote allocation plan for the money.

If it is the maximum denomination priority method, if y _{1 is} as large as possible, then 55+2t is as large as possible, and -24 ≤ t ≤ -22, and t=-22, y ₁ =11, y ₂ =0 is obtained. Banknote dispensing plan.

If it is the minimum denomination priority method, if y _{2 is} as large as possible, then -110-5t is as large as possible, and -24 ≤ t ≤ -22, and t = -24, y ₁ = 7, and y ₂ = 10 is obtained. Banknotes and banknotes.

Another example: when the user withdraws the amount of 135,550 yuan, first determine the withdrawal amount: 135550 < (10000x15 + 5000x10 + 50x12 + 20x10), when the withdrawal amount is less than the total amount held by the financial terminal, the banknote: 10000x ₁ +15000x ₂ +50y ₁ +20y ₂ =M, there are 10000x ₁ +15000x ₂ =M-50y ₁ -20y ₂ =S. Where gcd(10000, 15000)=5000, because the number is not more than 135550 and can be divisible by 5000, the number is 135000, and the other is m=135000, and 10000x ₁ +15000x ₂ =135000 is calculated, and 2x ₁ +3x ₂ =27 is obtained. Matrix transformation of equations

It can be obtained that x ₁ = -27 + 3t, x ₂ = 27-2t, since 0 ≤ x ₁ ≤ 15, 0 ≤ x ₂ ≤ 10, ₉ ≤ t ≤ 13, and t is an integer, and t = 9, 10, 11, 12, 13, can have many sets of solutions: t = 9, x ₁ =0, x ₂ = 9, t = 10, x ₁ = 3, x ₂ = 7, t = 11, x ₁ = 6 , x ₂ = 5, t = 12, x ₁ = 9, x ₂ = 3, t = 13, x ₁ = 12, x ₂ =1. The method of performing banknote dispensing is the same as above, and will not be described here.

The cash dispensing unit 23 is configured to call the banknote dispensing result, and respectively dispenses the banknotes of the banknotes and the banknotes of the banknotes.

Preferably, the cash dispensing unit 23 comprises:

The first cash dispensing module is configured to call the banknote dispensing result with the smallest number of banknotes, and the banknotes of the banknotes and the banknotes of the banknotes;

The second cash dispensing module is configured to call the banknote dispensing result according to the user's selection, and respectively perform the banknotes of the banknotes and the banknotes of the banknotes.

Specifically, after the banknote distribution result is obtained according to the user's withdrawal amount, when the user does not make a selection, the banknotes are selected according to the default banknotes selected by the financial terminal, that is, according to the minimum number of banknotes w, that is, the banknotes are bundled. The scheme with the largest amount of money is issued When the banknotes are issued, the banknotes can reduce the time for banknotes, save time for financial terminals, and reduce the probability of failure. In addition, it is also possible to dispense money according to the user's choice. For example, the user can select the maximum number of bundles to be dispensed or the total number of sheets of coins to be dispensed.

Preferably, the cash-out control system of the financial terminal further includes:

The third convention number determining unit is used to determine the maximum common denomination of the bundle amount of the bundle and the denomination of the banknote;

The withdrawal amount judging unit is configured to determine whether the user withdrawal amount can be divisible by the maximum bundle amount of the bundled banknotes and the maximum common denomination of the banknote denomination; if the user withdrawal amount cannot be the bundled amount of the bundled bundle When the maximum common divisor of the denomination of the banknote is divisible, the result of the failure to return the banknote is returned.

Specifically, after receiving the withdrawal amount input by the user, first determining the withdrawal amount: if the user withdrawal amount cannot be divisible by the maximum bundle amount of the bundled denomination, the current financial terminal cannot be given The amount of withdrawal required by the user, the payment of the banknote failed.

For example, suppose the financial terminal equipment is equipped with two kinds of bundles, 15 bundles of 10,000 yuan and 15 bundles (that is, 15 bundles of bundles with a value of 10,000 yuan), 10 bundles of 15,000 bundles, and 10 bundles. There are 12 sheets with a denomination of 50 yuan for banknotes and 10 sheets with a denomination of 20 yuan, ie A ₁ =10000, A ₂ =15000, X ₁ =15, X ₂ =10, B ₁ =50 , B ₂ = 20, Y ₁ = 12, and Y ₂ = 10.

If the user withdraws the amount of 35,545 yuan, since the maximum common divisor of (10000, 15000, 50, 20) is 10,35545%gcd(50,20)=5≠0, the banknotes fail;

Or the user withdrawal amount is 135,545 yuan, because the greatest common divisor of (10000, 15000, 50, 20) is 10,135,545%gcd(50,20)=5≠0, and the current financial terminal cannot give the amount stated by the user. The banknote failed.

In the second embodiment of the present invention, the information obtaining unit acquires the banknote information and the banknote information of the current financial terminal, and the banknote dispensing unit dispenses the banknotes of the user, and obtains the banknote dispensing result, and respectively bundles the banknotes when dispensing the banknotes. The banknotes of the banknotes and the banknotes of the banknotes yield at least one type of banknotes, and then the banknotes are issued according to the selected banknotes, and the bundles of bundles can be large when the bundles are discharged. It satisfies the need of large-value banknotes, shortens the time for issuing notes, and reduces the probability of failure when the banknotes are issued. The banknotes can be used to issue the amount of money required by the user, increasing the range of the amount of money issued by the user; In addition, in the calculation of the banknotes in the present embodiment, the combination of the banknotes and the banknotes and the banknotes are calculated, so that the banknotes can be as large as possible, and the banknotes are as small as possible, further shortening. The time for issuing the banknotes; and because of the multiple banknotes obtained during the banknote dispensing process, the user can also select the banknotes as needed to improve the user experience.

For example, 20 banknotes with a denomination of 100 yuan are bundled into one bundle, or 50 banknotes with a denomination of 20 yuan are bundled into a bundle. The setting of each bundle of banknotes can also be set as needed. A banknote is a single banknote of various denominations, such as a banknote with a denomination of 50 yuan. The bundle information includes: a bundle type n, a bundle amount A ₁ , A _{2 ,} , ..., A _n of each bundle and the number of available bundles of each bundle X ₁ , X _2, , ... , X _n , X∈Z; the banknote information includes: the type of the banknote m, the denominations B ₁ , B _2, , ..., B _m of each banknote and the amount of the banknotes Y ₁ , Y _{2 for} each denomination _, ,...,Y _m ,Y∈Z.

Preferably, the processor is specifically configured to:

According to the user withdrawal amount and the bundle information, the banknotes of the bundles are dispensed, and the banknote distribution scheme and the banknote tailnote are obtained; according to the banknote tailnotes and the banknote information, the banknotes of the banknotes are dispensed, Determining a banknote dispensing scheme; selecting one of the banknote dispensing schemes, selecting one of the banknote dispensing schemes according to the number of banknotes corresponding to the selected banknote dispensing scheme; The banknote dispensing scheme and the selected banknote dispensing scheme determine at least one of the banknote dispensing results.

Preferably, the processor performs the whole banknote dispensing according to the user withdrawal amount and the bundle information, and obtains the banknote dispensing scheme and the banknote ending number, specifically for:

Determining a maximum common divisor of the bundle amount of each bundle according to the bundle information; determining a tail of the banknote according to the withdrawal amount of the user, so that the difference between the withdrawal amount of the user and the tail of the banknote can be described The maximum common divisor of the bundled bundle amount is divisible; the banknote mantissa meets: 0 ≤ banknote tail number ≤ user withdrawal amount; at least one type of banknote dispensing scheme is determined according to the banknote tail number.

Preferably, when the processor performs the banknote dispensing according to the banknote tailnote and the banknote information, and determines the banknote dispensing scheme, the processor is specifically configured to:

Determining, according to the banknote information, a maximum common divisor of the banknote endings and the banknote denomination; determining at least one of the banknotes according to at least one of the banknotes and the maximum common divisor of the banknote denominations The banknote dispensing scheme.

Specifically, according to the user withdrawal amount M, the banknotes of the current financial terminal and the banknotes are dispensed; the amount of each banknote required for the current user withdrawal amount M is set to x ₁ , x _2, respectively _. ,...,x _n ,x∈Z; the number of required banknotes is y ₁ , y _2, ,...,y _m ,y∈Z; where 0≤x ₁ ≤X ₁ ,0≤x _2, ≤ X _2, ,..., 0 ≤ x _n ≤ X _n ; 0 ≤ y ₁ ≤ Y ₁ , 0 ≤ y _2, ≤ Y _2, , ..., 0 ≤ y _m ≤ Y _m . Then there are: M = A ₁ x ₁ + A ₂ x ₂ + ... + A _n x _n + B ₁ y ₁ + B ₂ y ₂ + ... + B _m y _m .

When the user's withdrawal amount M is dispensed, first determine a banknote tail w, and dispense the banknote according to the banknote tail w, at this time: w=B ₁ y ₁ +B ₂ y ₂ +.. .+B _m y _m , therefore, if the total amount of the banknotes is S, then: Mw=S=A ₁ x ₁ +A ₂ x ₂ +...+A _n x _n . Therefore, the value of x ₁ , x _2, , ..., x _n is determined according to the tail number w of the banknote _, and the banknote dispensing scheme of the banknote can be determined. Then, according to the determined banknote mantissa w, the value of y ₁ , y _2, , ..., y _m is determined by the formula w=B ₁ y ₁ +B ₂ y ₂ +...+B _m y _{m to} determine the banknote The banknote scheme.

For a certain banknote mantissa w, the equation w=B ₁ y ₁ +B ₂ y ₂ +...+B _m y _m can have multiple sets of solutions, ie each determined banknote tail w corresponds to at least one match Banknote scheme; and in the case where the banknote mantissa is determined, there may be at least one set of solutions for the equation Mw=S=A ₁ x ₁ +A ₂ x ₂ +...+A _n x _n ; The banknotes respectively select one of the obtained banknote dispensing schemes and one of the banknote dispensing schemes, and can form a banknote matching result matching the user withdrawal amount, and the banknote dispensing result has at least one.

In determining the banknote dispensing scheme, an integer solution of the equation Mw = S = A ₁ x ₁ + A ₂ x ₂ + ... + A _n x _{n is} determined. At this time, first determine the maximum common divisor (gcd) of the single bundle amount A ₁ , A _2, , ..., A _n of each bundle, and record it as gcd (A ₁ , A _2, ,..., A _n ); determine a banknote mantissa w such that (Mw) satisfies: 0 ≤ (Mw) ≤ M, and can be divisible by gcd (A ₁ , A _2, , ..., A _n ); according to the determined banknote tail number w An integer solution of the equation Mw = S = A ₁ x ₁ + A ₂ x ₂ + ... + A _n x _n is obtained. In addition, if S cannot be divisible by gcd (A ₁ , A _2, , ..., A _n ), the current banknotes w, the banknotes fail to be dispensed, and the banknotes are adjusted w, and then the banknotes are dispensed.

For the solution process of the integer solution of S=A ₁ x ₁ +A ₂ x ₂ +...+A _n x _n , refer to the solution process of equation (1), and details are not described herein again. The banknote dispensing scheme is determined based on an integer solution of S = A ₁ x ₁ + A ₂ x ₂ + ... + A _n x _n .

After the banknote dispensing scheme is obtained, the banknotes are dispensed according to the determined number of banknotes w. From w=B ₁ y ₁ +B ₂ y ₂ +...+B _m y _m , it can be seen that when the banknotes are dispensed, the greatest common divisor of w, B ₁ , B ₂ , ... B _{m is} determined, Then, according to the solution method of equation (1), the integral solution of the equation w=B ₁ y ₁ +B ₂ y ₂ +...+B _m y _m is obtained to obtain the banknote dispensing scheme of the banknote.

Optionally, when the banknotes are dispensed according to the user's withdrawal amount, the bundle amount of each bundle of bundles can be regarded as the denomination of the banknotes. For example, a bundle of 10 bundles of 100 yuan bills can be regarded as one bundle. A banknote with a face value of 1,000 yuan is then dispensed with the banknotes by the user's withdrawal amount: M = (A ₁ x ₁ + A ₂ x ₂ +... + A _n x _n )+(B ₁ y ₁ +B ₂ y ₂ +...+B _m y _m ), can be dispensed according to the following four banknotes:

1), the principle of the maximum number of bundles of bundles, at this time

As large as possible

2), the principle of the maximum amount of banknotes, at this time

As large as possible

3), the principle of the minimum number of loose notes, at this time

As small as possible

4) The principle of the minimum amount of banknotes, that is, the principle of the minimum number of banknotes, at this time

As small as possible

Preferably, the method of dispensing money of the banknotes can be divided into five types: an average billing method, a moving average method, a total number of sheets minimum method, a maximum denomination priority method, and a minimum denomination priority method. The specific calculation process is referred to the first embodiment, and details are not described herein again.

The output device 33 is configured to call the banknote dispensing result to respectively perform banknotes for banknotes and banknotes for banknotes.

Preferably, the output device is specifically configured to:

Calling the result of the banknote with the smallest number of banknotes, and the banknotes of the banknotes and the banknotes of the banknotes;

Or, according to the user's choice to call the banknotes, the banknotes of the banknotes and the banknotes of the banknotes are separately dispensed.

Specifically, after the banknote distribution result is obtained according to the user's withdrawal amount, when the user does not make a selection, the banknotes are selected according to the default banknotes selected by the financial terminal, that is, according to the minimum number of banknotes w, that is, the banknotes are bundled. The scheme with the largest amount of banknotes is used for banknotes. In this case, the banknotes can minimize the time for banknotes, save time for financial terminals, and reduce the probability of failure. In addition, it is also possible to dispense money according to the user's choice. For example, the user can select the maximum number of bundles to be dispensed or the total number of sheets of coins to be dispensed.

Preferably, the processor is further configured to:

Determining the maximum common denomination of the bundle amount of the bundle and the denomination of the banknote; and determining whether the user withdrawal amount can be divisible by the maximum bundle of the bundled bundle and the maximum common denomination of the banknote denomination; correspondingly, the output The device is further configured to return a banknote failure result when the user withdrawal amount cannot be divisible by the single bundle amount of the bundled banknote and the maximum common denomination of the banknote denomination.

Specifically, after receiving the withdrawal amount input by the user, first determining the withdrawal amount: if the user withdraws the amount If the single bundle amount that cannot be bundled is divisible by the maximum common denomination of the banknote denomination, the current financial terminal cannot give the amount of withdrawal required by the user, and the banknote fails.

For example, suppose the financial terminal equipment is equipped with two kinds of bundles, 15 bundles of 10,000 yuan and 15 bundles (that is, 15 bundles of bundles with a value of 10,000 yuan), 10 bundles of 15,000 bundles, and 10 bundles. There are 12 sheets with a denomination of 50 yuan for banknotes and 10 sheets with a denomination of 20 yuan, ie A ₁ =10000, A ₂ =15000, X ₁ =15, X ₂ =10, B ₁ =50 , B ₂ = 20, Y ₁ = 12, and Y ₂ = 10.

If the user withdraws the amount of 35,545 yuan, since the greatest common divisor of (10000, 15000, 50, 20) is 10,35545%gcd(50,20)=5≠0, the dispensing of the banknote fails.

In the third embodiment of the present invention, the input device acquires the banknote information and the banknote information of the current financial terminal, and the processor allocates the banknotes to the user's withdrawal amount, and obtains the banknote dispensing result, and separately distributes the banknotes when dispensing the banknotes. The banknotes of the banknotes and the banknotes are at least one type of banknotes, and then the output device performs the banknotes according to the selected banknotes. When the banknotes are bundled, the amount of bundles can be large, which satisfies the large The need for cash withdrawal, while shortening the time for issuing notes, reduces the probability of failure when the banknotes are issued; and the banknotes can be used to issue the amount of money required by the user, increasing the range of the amount of money issued by the user; In the embodiment, when calculating the banknotes, the banknotes are combined with the banknotes and the banknotes are combined to calculate, so that the banknotes can be as large as possible, and the banknotes are as small as possible, further shortening the time of banknotes. And because a variety of banknotes are obtained during the dispensing process, the user can also select the banknotes as needed to improve the user experience.
