Description

Data transmission method based on fund system and related equipment

Technical Field

The present invention relates to interactive systems, and in particular, to a data transmission method and related devices based on a fund system.

Background

With the development of financial services, more and more sales services of financial products are also circulated in the market. Meanwhile, the reimbursement business of financial products, such as fund reimbursement business, is also developed vigorously. The bridge work between the fund company and the user of the fund brokering company needs to send the transaction information of the user to the fund company for transaction, and meanwhile, the transaction information fed back by the fund company needs to be received and collated. This work was done early by manual billing, but as technology developed, the fund brokerage system became the primary processing system. The service flow inside a general fund affiliation company is complex and needs to process massive data. If the fund-brokering company develops the brokering system by itself, a great deal of manpower and financial resources are required. Therefore, purchasing a third party's fund-brokering system is a major means of fund-brokering companies.

When data is transmitted between fund affiliate companies and fund companies, in order to reduce the weight of data transmission, text in the TXT format is generally used for transmission. The transmitted text is mainly divided into an index file and a data file. The data file is composed of a plurality of transmission data, and the transmission data comprises file identification, file version number, file creator, file receiver, date, file number, file name …, file ending identification and the like. In the existing data transmission process, the meaning and data length represented by each row of data are defined, for example, the first row is a file identifier, the length is 8 bytes, and the seventh row to the ninth row do not set a character string of the data length. The file identifier is generally set as "OFDCFIDX", the length is 8 bytes defined, and the file version number is 22, which does not satisfy the predefined 8 bytes, so space or zero is used for padding. Wherein, the "OFDCFEND" is the end of file identifier. The data file is formed by splicing a plurality of data messages, and the data messages comprise file identification, file version number, file creator, file receiver, date, summary table number, file type code, sender, receiver, field number, field name, record number, record and file end identification. In the data file, starting from the first byte and counting 8 bytes backwards, the starting point identifier of the data file is obtained, and the starting point identifier in the data file is the same as the starting point identifier in the index file. And counting eight bytes from the last byte of the data file to the front to obtain the end identifier of the data file, wherein the end identifier in the data file is the same as the end identifier in the index file. For convenient display, three fields of fund codes, unit reddening and reddening time are selected for display description, and the field lengths of the three fields are respectively 6 bytes, 16 bytes and 8 bytes. If the reddening content of a record of a certain data file is as follows: "fund 000120 is reddened 0.45 yuan per share at 1/7/2021, then the data shown by the corresponding three fields is shown as: 000120000000000000004520210701. if the reddening content of a record is as follows: "fund 000223 is reddened 1.50 yuan per share on 1/7/1/2021", then the data shown by the corresponding three fields is shown as: 000223000000000000015020210701. since there are only two records, and the length of the byte corresponding to a record is 16, it is necessary to perform padding with a space or zero. In this embodiment, zero is used for completion.

Therefore, the byte length of the existing scheme is preset and cannot be adjusted, and the insufficient part needs to be completed by zero or a space, so that the whole file is too large and inconvenient to transmit. In addition, during parsing, the length of each byte needs to be recorded to achieve accurate parsing, and if the set byte length changes, the parsing program needs to be rewritten, which causes resource waste.

As shown in fig. 3, the present embodiment provides a data transmission method based on a fund system, and the data transmission method based on the fund system includes the following steps:

s10, obtaining an information file to be transmitted, wherein the information file comprises a plurality of field data.

Specifically, the fund company end generates various information files required to be transmitted to the fund brokering end in the interaction process with the fund brokering end and the operation process of the fund company end. Taking the common dividend as an example, every other settlement period, the fund company end needs to send the dividend result corresponding to each fund purchased by each user in the settlement period to the fund brokerage end. Also for example, when a user plans to stop purchasing a fund, the fund company needs to transmit the user's revenue during that period to the fund-brokering company. The present embodiment refers to information file containing information transmitted from the fund company side to the fund brokerage side.

The information file is provided with specific operation information, time and other information, and the content of each information is represented by field data.

And S20, determining the coding identifier and the coding value corresponding to each field data according to a preset coding mapping table to obtain a plurality of first coding groups.

Specifically, a coding mapping table is preset, in which a corresponding coding identifier is set for each field type of field data, and a corresponding coding value is set for different field contents under each field type. As shown in fig. 4, the code corresponding to "file type" is identified as "1"; the code corresponding to the file version number is marked as 2; the code corresponding to the 'file creator' is marked as '3'; the code corresponding to the 'file receiver' is marked as '4'; the code corresponding to the "date" is marked as "5"; the code identifier corresponding to the summary table number is 6; the code identifier corresponding to the file type code is 7; the code corresponding to the "sender" is identified as "8"; the code corresponding to "receiver" is labeled "9"; the code corresponding to the "number of fields" is identified as "10"; the code corresponding to the "fund code (FundCode)" is identified as "11"; the coding mark corresponding to the unit reddish (DividendPerUnit) is 12; the code corresponding to the "reddening time (divdenstdate)" is marked as "13"; the code corresponding to the record number is marked as 14, namely the number of the information specifically related to the bonus in the bonus file; the code corresponding to "extension field 1" is identified as "500"; the code corresponding to "extension field 2" is identified as "501"; the code identifier corresponding to the check protocol is 998; the code corresponding to the "check bit" is identified as "999".

For example, the field type of a certain field of data is date, the specific field content is 03-2020, the corresponding code identifier of that piece of data is 5, and the code value corresponding to the field content is 20200303. The field type is a file receiver, a corresponding code value is preset for each file receiver (namely, a fund sales terminal) which is in contact with the fund company, the code identifier corresponding to the file receiver is 4, the code value corresponding to the fund sales terminal a is 1, and the code value corresponding to the file receiving terminal in the information file which needs to be sent to the fund sales terminal a is 1.

Therefore, after the field data in the information file is obtained, the coding identifier and the coding value corresponding to the field data are determined according to the field type and the field content of each field data, and the first coding group corresponding to each field data is obtained. After the first coding groups corresponding to all the field data are determined, a plurality of first coding groups can be obtained.

In the embodiment in this market, the first encoding group corresponding to each field data includes an encoding identifier and an encoding value corresponding to the field data, and the encoding identifier and the encoding value may be formed by combining characters such as arabic numerals and letters. In order to distinguish the code identifiers and the code groups in the first code group, in one implementation, the code identifiers may be numbers, and the code values may be letters, that is, the format of the code identifiers and the code values may be different. In another implementation, the coded identifier and the coded value are connected by a pointer, which is a connection symbol with a pointing property, such as a colon, an arrow, a dash, an equal sign, and the like.

S30, determining a data coding group corresponding to the file format in the first coding group according to each preset file format and the coding mapping table, and taking the data coding group and the format coding group corresponding to the file format as a second coding group corresponding to the file format.

Specifically, the file transmitted from the fund company side to the fund brokerage side generally consists of two files, one is an index file and the other is a data file. The index file is smaller than the data file, so that the fund sales end can conveniently read and retrieve, and the data file is larger and has detailed information. The index file and the data file are both obtained based on the original information file, but the contents of the index file and the data file are different. That is, the file format of the index file and the file format of the data file, that is, the index file format and the data file format, determine the first coding arrays corresponding to different ones.

Therefore, according to the preset file format, the data coding group corresponding to the file format in the first coding group is determined. Specifically, the data encoding set includes an index file data set and a data file encoding set. And determining a first coding group corresponding to the index file as an index file coding group according to the index file format, and determining a first coding group corresponding to the data file as a data file coding group according to the data file format. Of course, if other files, such as system parameters, are added to the original index file and data file at the fund company end and the fund brokerage end, the other files may also be used as another file, so as to generate the corresponding data code set.

In order to reduce the volume of the file, this embodiment sets, in advance, coding identifiers and coding values corresponding to different file formats in a coding mapping table, for example, a coding identifier corresponding to a file format is 1, a coding value corresponding to a file format of an index file is 01, and a coding value corresponding to a file format of a data file is 02. And after the file format is determined, determining the corresponding coding identification and coding value, and generating a format coding group by adopting a mode of generating a first coding group. And then the data coding group and the format coding group are used together as an index file or a second coding group corresponding to the data file.

And S40, classifying the second coding group according to a preset classification rule to obtain a plurality of coding group sets.

Specifically, a classification rule is preset for classifying the second encoding groups, and the classification is mainly to combine the second encoding groups with different importance degrees and different types, so that the subsequent fund affiliation end can be conveniently processed.

In the first mode of this embodiment, all the second code groups are directly used as a class, and a code group set is obtained.

In another embodiment, the number of code group sets and which are defined as a code group set by the requirements of the fund company. For example, as shown in fig. 5, a second code group corresponding to "file type", "file version number", "file creator", "file receiver", "field number", and "recording number" is used as a code group set.

And S50, integrating each coding group set according to a preset integration rule to obtain a target coding sequence corresponding to the coding group set.

Specifically, the second encoding group in the encoding group set is split in units of the encoding group set. An integration rule is preset, and then each second code group in the code group set is processed through the integration rule. The second code groups in the code group set are scattered, so that the second code groups need to be integrated together in a mode to obtain the target code sequence.

In a first implementation manner of this embodiment, for each of the code group sets, a second code group in the code group set is sorted according to a preset sorting rule to obtain a first code sequence. As shown, for the first encoding group set, the preset ordering order is: "file type", "file version number", "file creator", "file receiver", "number of fields", "number of records"; for the second encoding group set, the predetermined ordering order is: "Fundcode", "DividentPerUnit", "DividentDate", "time to redden", "Fundcode", "DividentDate", "KindCode", "DividentTate", "KindTokyo (KindCode)".

And then, according to a preset separator, separating the second coding group in the first coding sequence to obtain a target coding sequence corresponding to the first coding sequence. A plurality of separators are preset, in this embodiment, the separators include null characters, line separators, and other special characters, and the special characters include "|", and the like. The null character is 0x00 in ASCII code, indicating a null character. The second code group in the first code sequence is separated by using a separator, and the separator is added before or after the second code group.

In another implementation, to increase the ease of subsequent integration of the target coding sequence, the separators include intra-group separators and inter-group separators in this embodiment. As the name implies, the intra-group delimiter is used to separate the first encoding group within one encoding group set, and the inter-group delimiter is used to separate between encoding group sets.

Firstly, carrying out separator modification on a second code group in the file code sequence according to a preset group separator on each first code sequence obtained after sequencing to obtain a second code sequence corresponding to the first code sequence. In fig. 5, a box is used to represent a null character, and the intra-group separator used is a null character.

And then adding a preset interclass separator to the tail end of the second coding sequence to obtain a target coding sequence corresponding to the second coding sequence. Therefore, subsequently, after the fund sales end obtains the transmission file and analyzes the transmission file to the target coding sequence, the data can be accurately split according to the interclass separators without reading one by one and analyzing the data independently.

Further, in order to facilitate the fund affiliate company to conveniently and quickly locate the coding group sequences that are encoded differently, the component separator employed in the present embodiment is a branch character.

The existing scheme lacks a verification mechanism for data transmitted by a fund company terminal, and in order to improve the authenticity of the data and reduce the risk of errors, the verification mechanism is added in another process of generating a target coding sequence.

Firstly, aiming at each first coding sequence, according to a preset intra-group separator, a second coding group in the first coding sequence is separated to obtain a second coding sequence corresponding to the first coding sequence. The manner of adding the element separators can be referred to above, and is not described herein again.

And then calculating the second coding sequence according to a preset check rule to obtain a check bit corresponding to the second coding sequence. And presetting a check rule, wherein the check rule is used for encrypting the second coding sequence to obtain a check bit. A common verification rule is to directly set a verification protocol, where the verification protocol is implemented by using an encryption algorithm, such as md5 algorithm and SHA1 algorithm, and the second coding sequence is used as data to be encrypted, and the data is encrypted and calculated by using the verification protocol to obtain a verification bit corresponding to the verification protocol. But the encryption sequence obtained by the general check protocol is longer, even longer than the encrypted content, and the length of the target coding sequence is increased. Therefore, in this embodiment, the check rule includes a check protocol and an extraction rule. And firstly, encrypting the second coding sequence by adopting a check protocol to obtain an encrypted sequence corresponding to the second coding sequence. And then extracting the characters with specific positions and specific lengths in the encrypted sequence as check bits according to an extraction rule. In fig. 5, the adopted check algorithm is md5, the extraction rule is to extract the first four bits, so that the first four bits correspond to the first second encoding sequence, and the encrypted sequence obtained after encryption is "3446630 d0fe7c0c0dfd925fc47f7d0a 4" and the corresponding check bit is 3446.

And adding a check identifier in the coding mapping table in advance to obtain a check bit, and generating a check coding group corresponding to the second coding sequence according to the check identifier corresponding to the check rule and the check bit. The check mark includes a check protocol mark and a check bit mark, for example, the check code group in fig. 5 is a combination of two code groups, including a check mark code group composed of the check mark and a check value thereof, and a check value code group composed of the check bit mark and the check bit, wherein the generated check mark code group and the check value code group may be generated in the manner of generating the first code group as described above, and are not described herein again.

And then adding the check code group to the second coding sequence to obtain a third coding sequence. The check code group may be located at the beginning, end, or other position of the second code sequence, but is not limited thereto, and fig. 5 illustrates that it is added to the end of the second code sequence. It is noted that since the check code group is also a code group, the second code group at the end of the second code sequence should be added with an intra-group delimiter at the back end before being added to the end of the second code sequence. This step may be performed at the time of generating the second code sequence, i.e., at the time of adding the intra-group delimiter, the intra-group delimiter is set at the end of each second code group. In addition, when the check mark coding group and the check bit coding group are added to the second coding sequence, an intra-group separator can be added between the two groups for separation.

And finally, adding a preset interclass separator to the tail end of the third coding sequence to obtain a target coding sequence corresponding to the second coding sequence. By adding the component separators, different coding group sets are divided, a plurality of target coding group sequences can be read at the subsequent fund sales end at the same time, and the reading speed is improved.

And S60, arranging the target coding sequence according to a preset arrangement rule to obtain a transmission file corresponding to the information file.

Specifically, an arrangement rule is preset, each code group set obtains a target code sequence, the transmission file is a set of different target code sequences, the arrangement rule is to arrange a plurality of target code rules to obtain a file arranged according to a certain rule, and the file can be an index file or a data file. After the data file and the index file are obtained, the transmission file corresponding to the information file obtained at the beginning is obtained.

And finally, the transmission file can be transmitted to the fund sales terminal based on the communication connection between the fund company terminal and the fund sales terminal.

And after the fund sales terminal obtains the transmission file, aiming at the transmission file of each file format and each target coding sequence in the transmission file, extracting a second coding group in the target coding sequence according to the position of a check coding group appointed with the fund company terminal in advance. And then, encrypting the second coding group by adopting a check protocol which is the same as that of the fund company end to obtain a corresponding verification value. And finally, comparing the verification value with the check bits in the check coding group. If the two codes are the same, the second code group is analyzed according to the code mapping table which is the same as that of the fund company end, and the required information file is obtained.

By comparing fig. 5 with fig. 6, the transmission file obtained by the scheme is significantly smaller, simpler, more flexible and safer.
