Abstract

PURPOSE:To attain the transfer of all data stored in plural files which are contained in a single group with a single operation by dividing the transfer data into groups. CONSTITUTION:When a group is designated at the transmission side via a keyboard 1-1, the data processing 1-2 retrieves a group control file 2-1 of a data storage part 1-2 at input of a transfer data transmission request with the designated group defined as a key. Thus the type of the transfer data is taken out of the designated group. Then a type control file is retrieved with the taken-out type used as key for extraction of the date of production and the frequency of production of the transfer data. In the same way, a data control file is retrieved and all data stored in a series of files are taken out as the transfer data. These transfer data are sent to a data transfer part 1-4 and transmitted through a communication circuit 1-5. So is with the reception side, that is, all data stored in plural files included in a single group are transferred with a signal operation since the transfer data are divided into groups.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a file transfer device, and particularly to a file transfer device that transfers transfer data generated by a data processing unit and stored in a file through a communication line.

[Conventional technology]

In conventional file transfer devices, the operator specifies the file containing the transfer data to be transferred and the destination to transfer data, provided that files with the same specifications exist on the transfer source and transfer destination. As a result, one file is transferred in one transfer process.

[Problem to be solved by the invention]

In the conventional file transfer device described above, the transfer process is performed on a physical file basis, and it is necessary that files with the same specifications exist at the transfer source and transfer destination. If the file exists, it has the disadvantage that it requires the operator to issue transfer instructions N times.

Furthermore, in conventional file transfer devices, if the same type of transfer data occurs multiple times on the same day, those transfer data are stored in a single file in an additional format. Even if data is created by mistake, the transferred data cannot be deleted.

An object of the present invention is to provide a file transfer device that can collectively transfer all transfer data in a plurality of files included in one group in one operation by grouping the transfer data. It is in.

[Means to solve the problem]

The file transfer device of the present invention includes: (A) a group management file that collectively manages the types of transfer data included in each group for each group of transfer data, and the creation date and number of times of creation for each type of transfer data; (B) A data storage unit that stores a type management file that collectively manages the transfer data, and a data management file that collectively saves the contents of the transfer data for each transfer data creation date and creation number; (B) transfer by performing data processing; A data processing unit that generates data, forms the group management file, the type management file, and the data management file and stores them in the data storage unit, and instructs data transfer for each group of transfer data as necessary. , (C) A series of transfers obtained by receiving a data transfer instruction from the data processing unit and searching the group management file, the type management file, and the data management file for the instructed group of transfer data. The data transfer unit is configured to include a data transfer unit that transfers data in bulk through a communication line.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a file transfer device of the present invention. Further, FIG. 2 is a storage information configuration diagram showing an example of the data storage section of FIG. 1.

The file transfer device of this embodiment, as shown in FIG.

, a data processing unit 1-2 that performs data processing, a data storage unit 1-3 that stores transfer data, etc., and a communication line 1-
5, and a data transfer unit 1-4 that transfers transfer data through the transfer unit 5.

The data storage unit 1-3 also stores a group management file 2-1 and a type management file 2-2, as shown in FIG.
and a data management file 2-3.

The group management file 2-1 includes transfer data groups G1, G2 . For example, the type of transfer data S1, S2 for group G1, the type S3 of transfer data for group G2, etc. As shown in S4, the types of transfer data included in each group are collectively managed.

The type management file 2-2 also contains the type S of the transferred data.
l, S2. . . . - The creation date and number of times the transfer data was created are collectively managed.

Furthermore, the data management file 2-3 includes transfer data types Sl, S2. . . . The contents of the transferred data are collectively saved for each creation date and number of times the data was created.

On the other hand, the data processing unit 1-2 generates transfer data by performing data processing, and also generates the group management file 2-11 type management file 2-2. A data management file 2-3 is formed and stored in the data storage section 1-3.

Then, the data processing section 1-2 instructs data transfer for each group of transfer data according to instructions from the keyboard 1-1 as necessary.

Therefore, upon receiving a data transfer instruction from the data processing section 1-2, the data transfer section 1-4 transfers data to the group management file 2 for the instructed group of transfer data.
-11 Type management file 2-2. Data management file 2
A series of transfer data obtained by searching for -3 is collectively transferred through the communication line 1-5.

Next, an example of the operation of the file transfer device of this embodiment will be described.

(a) When transmitting transfer data, when a request to transmit transfer data is input by specifying a group from the keyboard 1-1 on the transmitting side, the data processing unit 1-2 selects the specified group. The group management file 2-1 is searched for in the data storage unit 1-3 as an index key, and the type of transfer data of the designated group is extracted.

Next, the type management file 2-2 is searched using the type of transfer data as an index key, and the creation date and number of times of creation of the transfer data of that type are retrieved.

At this time, if the transferred data of that type has a sent or deleted flag, it is excluded from the search.

Then, the data transfer unit 1-4 searches the data management file 2-3 using the extracted creation date and number of creation times of the retrieved type as an index key.
give it to

Therefore, the data transfer unit 1-4 transfers the received series of transfer data to another file transfer device via the communication line 1-5.

Note that the data processing unit 1-2 continues searching until there is no more transfer data for the designated group.

(b) When receiving transfer data: On the receiving side, first, the data transfer unit 1-4 passes the received transfer data to the data processing unit 1-2.

Therefore, the data processing unit 1-2 uses the type and creation date of the received transfer data as keys, and uses the type management file 2-2 as a key.
2, and if the same type is not registered, it is registered in the type management file 2-2 as transfer data of the i-th creation number of that type, and if the same type exists and the creation number is i times, then , type management file 2-2 as i+1 times
Register. However, this operation is performed only for the first transfer data in a series of transfer data of the same type.

Then, the received series of transfer data of the same type is stored in the data management file 2-3 with a type 1 creation date 2 creation number and a serial number.

Note that the data processing section 1-2 continues to repeat this operation until there is no more data transferred from the data transfer section 1-4.

As described above, by grouping the transfer data, the file transfer device of this embodiment can collectively transfer all the transfer data in multiple files included in one group in one operation. I can do it.

Furthermore, by searching the group of transfer data, the date of creation of type 1, and the number of times of creation as index keys, the file transfer device of this embodiment can search for the group of transfer data, the date of creation of type 1, and the number of times of creation as index keys. By providing a flag in a part of the management file or data management file, the flag can be detected, and the i-th transfer data can be excluded from the transfer target.

〔Effect of the invention〕

As explained above, by grouping the transfer data, the file transfer device of the present invention can collectively transfer all the transfer data in multiple files included in one group in one operation. It has the effect of being possible.
