Description

Data processing method, device and system for calculating settlement amount based on multiple transactions

Technical Field

The application belongs to the technical field of currency settlement information data processing, and particularly relates to a data processing method, device and system for calculating settlement amount based on multiple transactions.

Background

In recent years, rapid development of information technology promotes rapid rise of cross-border transactions, and more merchants participate in cross-border transaction ranks directly or through online transaction platforms and the like.

Due to different currency exchange rates and policy influences among different countries, seller merchants and the like generally need to remit transaction currencies and convert the transaction currencies into corresponding domestic currencies. For example, currently, seller users of domestic merchants in China need to settle and enter the country after foreign transactions are converged into RMB. The state requires declaration of foreign currency entry settlement renowned currency according to the supervision requirement, and declaration of the foreign currency entry settlement renowned currency is required according to transaction dimension at present.

In the settlement process, based on the requirements of a monitoring organization, the settlement amount must be proved to be the transaction which really occurs abroad, and the settlement amount can be declared, and one transaction can be declared only once. Moreover, because the result of the piecing together of the amount of remittance of the transaction cannot be completely consistent with the amount of remittance proposed by the user when a plurality of transactions exist, even a large error is generated, the existing foreign exchange settlement method only adopts the mode of remitting the amount of data of a single transaction. The reason is that the amount of each settlement application is independently proposed by the user, the amount of the settlement application has no substantial relation with the actual amount of the settlement available to the user, and the user may input more than or less than the amount of the settlement available, or an integer settlement, or a decimal settlement, or multiple settlement, etc. For each transaction, there are refunds (refunds completed or underway) or other change factors after the payment is successful, and the remittance amount calculation needs to remove the refunds, so the remittance amount has a piecing concept. However, in the actual settlement process, there are large uncertain factors such as the number of check strokes and the settlement amount of the user, and it is difficult to meet the accurate settlement requirement of the user for simultaneously declaring multiple transactions.

Therefore, in the actual foreign exchange settlement method, only the sum of the single transaction data is settled. Obviously, the mode is inefficient in processing the settlement amount and cannot meet the precise matching requirement of the settlement amount, which is provided when a user simultaneously declares for multiple transactions.

Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The following describes in detail a data processing method, device and client for calculating a settlement amount based on multiple transactions according to the present application with reference to the accompanying drawings. FIG. 1 is a method flow diagram of an embodiment of a data processing method for calculating a settlement amount based on multiple transactions provided by the present application. Although the present application provides data processing method operational steps or apparatus configurations as illustrated in the following examples or figures, more or less operational steps or module configurations may be included in the method or apparatus based on conventional or non-inventive efforts. In the case of steps or structures where there is no logically necessary cause-and-effect relationship, the execution order of the steps or the block structure of the apparatus is not limited to the execution order or the block structure provided in the embodiments of the present application. When the data processing method or the module structure is executed in an actual data processing device or an end product, the data processing method or the module structure shown in the embodiment or the figure may be executed sequentially or executed in parallel (for example, in the environment of a parallel processor or a multi-thread process).

The embodiment of the application takes the settlement amount of the user in China as an application scene to explain the scheme in detail. Of course, it should be noted that the present application is not limited to the application of renminbi settlement calculation in china, and other services related to the same or similar algorithms and logics in the embodiments of the present application, such as multiple transaction settlement calculations in foreign currencies of different currencies, can be applied to the embodiments of the present application. Specifically, in the application scenario of the embodiment of the application, the seller users of domestic merchants need to merge foreign currencies of multiple transactions occurring abroad into RMB and enter the country. The state relates to foreign currency entry settlement into RMB, and declares according to the supervision requirement and the transaction latitude.

In general, there are many uncertain engines such as refund, declaration state change, new generation transaction, etc. for the transaction number and the settlement amount of the user, and in reality, the user is generally required to autonomously submit a settlement application. In the application scenario of the embodiment of the application, the user can randomly propose a settlement application amount, wherein the settlement application amount is the sum of settlement amounts of multiple transactions, the declaration amount is not less than the declaration application amount of the user of the actual seller, and the declared transactions are not allowed to be repeatedly declared. Specifically, as shown in fig. 1, in an embodiment of a data processing method for calculating a settlement amount based on multiple transactions provided by the present application, the method may include:

s1: and acquiring the settlement application amount of the user based on settlement application request information of the user, inquiring current settlement transaction data of the user, and judging whether the single transaction data marked as declared exists in the current settlement transaction data.

In the embodiment of the application, when a user needs to carry out a settlement application, the user can submit a corresponding settlement application request to a settlement processing system, and the settlement processing system can acquire settlement application request information of the user, acquire settlement application amount of the user from the request information and inquire current settlement transaction data of the user. In the embodiment of the application, a user can provide a settlement application based on multiple transactions, the user can provide the settlement application amount at the moment, and then the system inquires the information of the multiple current transactions of the user. In this embodiment, each transaction may be provided with a flag indicating the status of the transaction declaration, such as tag true or false, for indicating whether the transaction has been declared settled, and if so, tag of the transaction is set to true, otherwise, the transaction is set to false. Of course, other embodiments of the present application use other markers or ways to mark whether a transaction is declared, for example, setting a marker as mark or uniformly setting the name of a declared transaction to the beginning of the same character string, etc.

In the embodiment of the application, the settlement application amount of the user can be obtained based on the settlement application request information of the user, the current settlement transaction data of the user is inquired, and whether a single transaction data marked as declared exists in the current settlement transaction data or not is judged.

S2: if the judged result is that the single transaction data marked as declared does not exist, calculating the single negotiable amount of the single transaction data in the current negotiable transaction data, and calculating the transaction negotiable total amount of the user according to the single transaction negotiable amount; and judging whether the settlement application amount of the user is less than or equal to the calculated transaction settlement total amount.

And if the current settlement transaction data declared by the user does not have single transaction data already declared, further calculating the transaction settlement sum of the user. Specifically, the single amount of the acquirable sum of each transaction may be calculated, and then all the amounts of the acquirable sums of the users may be added to obtain the total amount of the transaction acquirable sum of the users. The transaction settlement total may be used to determine whether the settlement applied amount by the user meets the requirements. In this embodiment, in a hard scenario, it may be set that the next settlement calculation is performed when the settlement applied amount of the user is less than or equal to (including any one of the cases of less than or equal to) the transaction settlement total amount.

Specifically, for example, the amount of money requested by the user for the settlement is 200 yuan, and the user has 7 current settlement transaction data, where the amount of money of Trade4 is 140 yuan per unit transaction data, and the refund amount of money of Trade data is 40 yuan per unit transaction data, then the amount of money that can be settled per unit transaction is 100 yuan to 140 yuan to 40 yuan. The other 6 current knot-meeting transaction data are Trade1 ═ 10, Trade2 ═ 80, Trade3 ═ 70, Trade4 ═ 140(refund4 ═ 40), Trade5 ═ 270, Trade6 ═ 50(refund ═ 30), Trade7 ═ 200(refund7 ═ 140), the units are elements, and the knot-meeting mark tag is false. In the 7 transactions, 3 transactions have refunds, and the sum of single settlement is the sum of single transaction data-the refund sum of single transaction data, so Trade4 is 140-40 is 100, Trade6 is 50-30 is 20, Trade7 is 200 and 140 is 60. The user's transaction may then be concluded with a total of 10+80+70+ (140-40) +270+ (50-30) + (200-140) — 610 dollars. The calculated current verified and collectible total amount 610 yuan of the user is larger than the user settlement application amount 200 yuan, which can be considered to satisfy the settlement calculation requirement in the embodiment, and further settlement calculation can be performed.

Of course, if there is a single transaction data already declared in the current settlement transaction data, for example, the settlement flag tag4 of Trade4 is false, the transaction may be processed according to a preset processing method, for example, it is determined that the transaction is an illegal settlement transaction, and the transaction cannot participate in the settlement calculation, and the current settlement application is invalid. Or deleting the single transaction data marked as declared, and then carrying out settlement calculation. Thus, in another embodiment of the present application, the method further comprises:

s2': if the judged result is that single transaction data with the transaction mark declared exists in the current settlement transaction data, executing any one of the following implementation modes:

s201': judging that the current settlement application of the user fails;

s202': and deleting the single transaction data marked as declared from the current settlement transaction data of the user, and calculating the settlement amount by using the current settlement transaction data marked as the declared single transaction data.

FIG. 2 is a flow chart illustrating a method of processing data to calculate a settlement amount based on a plurality of transactions according to another embodiment of the present disclosure. In other embodiments, processing may also be performed according to a customized operation mode when the current settlement transaction data has a single transaction data that has been declared according to a specific application scenario. And will not be described in detail herein.

S3: and if the result of the judgment is that the settlement application amount is less than or equal to the transaction settlement total amount, matching and calculating a candidate transaction group of which the difference value between the single group total amount and the settlement application amount meets the matching requirement according to a preset settlement calculation mode based on the single settlement amount of the single transaction data in the current settlement transaction data.

By comparing the settlement application amount of the user with the transaction amount, whether the settlement application amount is less than or equal to the calculated transaction amount of the user can be determined. If less than or equal to, a candidate transaction group may be computed based on a single match of the negotiable amount for each transaction in the current closing transaction data. The candidate transaction group may include one or more single transaction data sets meeting the settlement calculation requirement in the current settlement transaction data of the user calculated according to a preset settlement manner. For example, the candidate transaction group described in this embodiment may include that the total sum of the single remittance amounts of all the single transaction data in the candidate transaction group matches the difference between the remittance application amounts, such as the difference is zero or minimum.

The preset settlement calculation mode can be calculated according to specific application scenarios or design requirements, and includes, but is not limited to, an algorithm utilizing permutation or combination, an algorithm utilizing known sum reverse solution combination, an alternate superposition algorithm adopting a specific mode, and an algorithm of obtaining a single transaction combination with a difference value meeting matching requirements through other matching calculations. The application provides an implementation mode for calculating the candidate transaction group, which can effectively match and calculate the candidate transaction group meeting the requirements. Specifically, in another embodiment of the data processing method for calculating a settlement amount based on multiple transactions, the step of matching and calculating a single group of total amount and the settlement application amount according to a preset settlement calculation method to obtain a candidate transaction group whose difference between the single group of total amount and the settlement application amount meets a matching requirement may include:

s301: searching whether single transaction data with the same amount as the user settlement application amount exists in the single settlement amount in the current settlement transaction data of the user; if yes, taking K single transaction data with the same amount as the settlement application amount in the current settlement transaction data as K candidate transaction groups respectively, wherein K is a positive integer;

s302: if no single transaction data with the same amount of money as the money requested by the user is available in the current money settlement transaction data, enumerating all single transaction combinations C (N, M) of the current money settlement transaction data by taking the single money of the single transaction data as an element, and calculating a single group total amount of the single money of each single transaction combination in the single transaction combinations C (N, M), wherein N is the number of the single transactions in the current money settlement transaction data of the user, and M is an integer and takes a value of [2, N ] ]respectively;

s303: judging whether a single transaction combination with a single group total amount identical to the settlement application amount exists in the single transaction combination C (N, M); and if so, taking the single transaction combination with the same amount as the settlement application amount as the candidate transaction group.

FIG. 3 is a flowchart illustrating an embodiment of a method for calculating candidate transaction groups in a data processing method for calculating a settlement amount based on multiple transactions according to the present application. Specifically, for example, in the application scenario of the current 7(N is 7) pieces of the current settlement transaction data, based on 200 pieces of the settlement application amount provided by the user, a single piece of transaction data with a resultable amount of 200 pieces of the current 7 pieces of the settlement transaction data, which is Trade1 ═ 10, Trade2 ═ 80, Trade3 ═ 70, Trade4 ═ 100, Trade5 ═ 270, Trade6 ═ 20, and Trade7 ═ 60, can be searched. If so, the single transaction data with the single amount of the resumable sum of 200 yuan can be directly used as the candidate transaction group. If there is a single transaction of data with a 200 dollar amount that can be concluded, multiple candidate transaction groups may be formed.

In the application scenario of this embodiment, if there is no single transaction data with the same amount of money as the amount of money requested by the user for the result, all combinations of the current result transaction data may be listed by using the single amount of money requested by each transaction of the 7 current result transaction data of the user as an element, for example, first listing a combination C (7, 2) of every two transactions in the 7 current result transaction data as a group, then listing a combination C (7, 3) of every three transactions in the 7 current result transaction data as a group, and so on, up to the combination C (7, 7), which is 120 combinations. Then, a single group total amount of single amount of money capable of being remitted in the current remittance transaction data included in each group of 120 combinations is calculated, and the single group total amount of which groups is the same as the remittance application amount is judged. If there is a single group with the same total amount as the settlement application amount, the group can be used as the candidate transaction group. For convenience of description in this embodiment, the combinations meeting the screening requirement of the candidate transaction group in the plurality of combinations, for example, 120 combinations, may be referred to as candidate groups. Among the above 120 combinations, the candidate groups having the same total amount as the amount of the aforementioned knot transfer application may include (Trade1+ Trade3+ Trade4+ Trade6 +10 +70+100+20 ═ 200), (Trade2+ Trade4+ Trade6 ═ 80+100+20 ═ 200). The two sets of candidate groupings may then be used as candidate transaction sets.

According to the implementation scheme of the embodiment of the application, all combinations can be listed by taking single settlement amount of each current settlement transaction data as an element, then the candidate groups with the single group total amount being the same as the settlement application amount of the user are searched in the combinations, and the searched candidate groups are used as the candidate transaction groups. Thus, a single transaction corresponding to the applied amount can be matched out of a plurality of transactions of the user accurately.

Optionally, in another embodiment of the present application, if there is no single group of candidate groups with the total amount equal to the amount of the settlement application in the combination C (N, M), the group with the smallest difference between the single group amount and the amount of the settlement application may be selected as the candidate transaction group. Therefore, a settlement declaration amount which is most accurate to the settlement application amount provided by the user can be calculated for the user on the premise of meeting the settlement rule. Specifically, in another embodiment of the data processing method for calculating a settlement amount based on multiple transactions, the method may further include:

s304: and if no single transaction combination with the same single group total amount as the settlement application amount exists in the single transaction combination C (N, M), calculating the difference value between the single group total amount of each single transaction combination in the single transaction combination C (N, M) and the settlement application amount, and selecting the single transaction combination with the minimum difference value and the single group total amount smaller than or equal to the settlement application amount as a candidate transaction group.

FIG. 4 is a flowchart illustrating an embodiment of a method for calculating candidate transaction groups in a data processing method for calculating a settlement amount based on multiple transactions according to the present application. Specifically, for example, if there is no single group of total sum of the 120 combinations of all C (N, M) that is 200 dollars of the settlement application amount of the user, the difference between each of the 120 combinations and the settlement application amount of 200 dollars can be calculated based on the single suspendable amount. In the embodiment of the present application, since there may be some groups whose single total amount is greater than the settlement application amount, for example, Trade4+ Trade1+ Trade2+ Trade6 is 210>200, the group with the minimum difference and the single total amount less than or equal to the settlement application amount may be selected as the candidate transaction group.

Of course, if the result of the determination is that the amount of the settlement application is greater than the transaction amount of the settlement application, for example, the amount of the settlement application is 650 yuan, and the amount of the settlement application is greater than 610 yuan, the settlement application may be processed according to a predetermined processing method, for example, it is determined that the settlement application does not meet the settlement application requirement, and the current settlement application is invalid. Of course, after the user is notified, the execution mode may be specifically set according to the design requirement, such as processing based on the amount of the settlement application that is modified by the user and meets the settlement application requirement. Thus, in another embodiment of the present application, the method further comprises:

s3': and if the judgment result is that the settlement application amount is larger than the transaction settlement total amount, judging that the current settlement application of the user fails.

FIG. 5 is a flow chart illustrating a method of processing data to calculate a settlement amount based on multiple transactions according to another embodiment of the present disclosure.

In the above embodiment, a single transaction data meeting the requirement of the user for the amount of the settlement application may be searched first, and if the single transaction data does not exist, all possible combinations of the current settlement transaction data may be listed further by using the combination as a unit. And then calculating the total sum of the single group of each group, searching whether a combination which is the same as the settlement application sum of the user exists, and if so, controlling the candidate transaction group by the combination. It should be noted that, in some embodiments of the present application, the candidate transaction group obtained by the final screening may include one, and of course, in other embodiments, a plurality of candidate transaction groups meeting the requirement may exist, which is not limited in the present application. For example, in this embodiment, a match with the difference of the amount of the settlement application may require zero, that is, a group with a single set of total amount equal to the amount of the settlement application in the single transaction combination C (N, M) is searched, and if such a group exists, the group may be regarded as a candidate transaction group.

In this embodiment of the application, when the result of the determination is that the settlement applied amount is less than or equal to the transaction settlement total amount, based on the single settlement amount of the single transaction data in the current settlement transaction data, the candidate transaction group whose difference between the single group total amount and the settlement applied amount meets the matching requirement is calculated in a preset settlement calculation manner in a matching manner.

S4: and taking the single group total amount of the candidate transaction group as the result declaration amount data returned to the user, and marking the single transaction data included in the selected candidate transaction group as the result declaration amount as the declared single transaction data.

As previously mentioned, the set of candidate transactions may include one or more sets of events. A group of candidate transaction groups can be selected according to scene design requirements or settlement rules and the like, and the selected single group total amount of the candidate transaction groups is used as the settlement declaration amount of the user. At the same time, selected transactions that are candidate transaction groups for the settlement of the declared amount may be marked as declared. Specifically, for example, in the application scenario of the above embodiment, two candidate transaction groups obtained by filtering the single group of total amount and the settlement application amount with the smallest difference (preferably 0) are: (Trade1+ Trade3+ Trade4+ Trade6 ═ 10+70+100+20 ═ 200) and (Trade2+ Trade4+ Trade6 ═ 80+100+20 ═ 200). One of the groups may then be selected according to predefined selection rules, such as selecting the group containing the most or least transaction data or the largest amount. In this embodiment, to reduce the transaction amount, it may be configured to preferentially select the candidate transaction group containing the most transaction data, that is, select the candidate transaction group containing 4 transactions from the two groups: (Trade1+ Trade3+ Trade4+ Trade6 is 10+70+100+20 is 200). Each transaction Trade in the candidate transaction group may then be marked as declared, e.g., Trade mark tag true for Trade1, Trade3, Trade4, Trade 6.

Based on the business specifications and the process algorithm set in the embodiment provided by the application, when multiple transactions are simultaneously declared, a settlement declaration amount which is most accurate to the settlement application amount provided by the user can be provided for the user on the premise of meeting the settlement rule, the autonomous settlement requirement of the user is met, and the user experience is improved.

In another embodiment of the data processing method for calculating the settlement amount based on multiple transactions, after the result of the judgment is that the settlement applied amount is less than or equal to the transaction settlement total amount, the single transaction data in which the single settlement amount is greater than the settlement applied amount of the current user in the current settlement transaction data can be deleted, so that the settlement calculation rate can be further improved. Fig. 6 is a schematic method flow diagram of another embodiment of a data processing method for calculating a settlement amount based on multiple transactions, specifically as shown in fig. 6, in another embodiment of the data processing method for calculating a settlement amount based on multiple transactions, after determining that the settlement applied amount of the user is less than or equal to the calculated transaction settlement amount, the method may further include:

s5: and deleting a single transaction datum of which the amount of the acquirable money is larger than the money application amount of the user from the current money transaction data of the user.

In the application scenario of the above embodiment, the single amount of the held transaction Trade, Trade. Obviously, the calculation amount of the settlement data after the single settlement amount larger than the settlement application amount is deleted is less than that before, so that the settlement calculation speed can be increased, and the settlement processing efficiency can be improved.

The application also provides another embodiment of a preset settlement calculation mode, which can be used for calculating a candidate transaction group in a convenient and quick matching manner and calculating the settlement declaration amount of the user. FIG. 7 is a flowchart illustrating a method for calculating a candidate transaction group according to another embodiment of the data processing method for calculating a settlement amount based on multiple transactions provided by the present application. Specifically, in another embodiment of the data processing method for calculating a settlement amount based on multiple transactions, the candidate transaction groups, which are based on a single settlement amount of single transaction data in the current settlement transaction data and match and calculate a difference between a single group total amount and the settlement application amount according to a preset settlement calculation method, and meet a matching requirement, may include:

s331: sorting the current settlement transaction data according to the amount dimension of the single transaction data;

s332: summing is carried out from one side of the maximum value of the sorting queue according to head and tail alternative values in sequence;

s333: comparing the current sum with the settlement application amount after each summation, stopping taking the value when the current sum is larger than the settlement application amount, and removing the value of the single transaction calculated by the current settlement;

5. the remaining 6 transactions are ordered from small to large according to the latitude of the amount:

Trade1＝10<Trade6＝20<Trade7＝60<Trade3＝70<Trade2＝80<Trade4＝100；

6. then summing the data from the head and the tail of the sequencing queue, starting to obtain from the tail of the queue, then obtaining the head, and sequentially alternating;

7. each pick is compared to the settlement application amount, and when the calculated amount > the settlement application amount, it is stopped and the current transaction is removed. As detailed steps in the example data:

the first step is as follows: trade4 is 100<200, accumulation is continued;

the second step is that: continuing to accumulate Trade4+ Trade1 when 110 is less than 200;

the third step: continuing to accumulate Trade4+ Trade1+ Trade2 when 190 is less than 200;

the fourth step: stop when Trade4+ Trade1+ Trade2+ Trade6 is greater than 210> 200;
