Abstract

PURPOSE:To transfer plural files by a single file transfer, to simplify the operation, and to shorten the processing time by synchesizing plural files to a single file. CONSTITUTION:By reading a parameter file 2, and obtaining a file name, a device name and a medium name of a transmission original, file transfer object files are synthesized to the single file by using a file synthesizing means 6. Subsequently, it is transferred and written in the input/output means 10 of a host equipment 9 by using a file transfer means 8. After write is completed, one file written and synthesized is decomposed by using a file decomposing means 13, and written in the input/output means 10 again. Since the host equipment 9 is operated in multiplication, read and write of the same file are generated from different terminals, therefore, the exclusive control of a file unit is executed by using an exclusive control means 15. A mail file generating means 5 and a mail file decoding means 11 are used at the time of judging a transfer file in a program.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file transfer device for transferring a file between a terminal device and a host device.

[0002]

2. Description of the Related Art Conventionally, file transfer has been performed in file units, that is, one file at a time. Therefore,
In the case of transferring a plurality of files, the operator repeatedly requests the transfer of the next file after the transfer of one file is completed.

[0003]

However, when the number of files to be transferred is extremely large, the number of times the operator requests the file transfer is increased, and even if the operator's request is automated, the file transfer will be one file at a time. The programs on the host side and the host side operate for the number of files that are transferred alternately, and the processing time becomes extremely long.

The present invention solves such a problem in the conventional transfer of a plurality of files, and allows the operator to perform only the input operation for confirming the start and end of the file transfer, and the processing time is short. With the goal.

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, FIG. 2 is a flow chart for explaining the operation in this embodiment, FIG. 3 is a diagram showing the format of a parameter file in this embodiment, and FIG. 4 is this embodiment. FIG. 5 is a diagram showing a format of a mail file in the example, and FIG. 5 is a diagram showing a format of a combined file transmitted / received in the present embodiment.

In this embodiment, the terminal side is provided with a keyboard 1 as an input means, a parameter file 2 describing a file to be transmitted / received, an input / output means 3, and a terminal device 4. In the terminal device 4, a mail file creating means 5 for creating a mail file describing a file name, a medium name, and a device name to be received when receiving from a host, and a file synthesizing means 6 for synthesizing a plurality of files into one file. When,
It has a file decomposing means 7 for decomposing the received combined file into a plurality of files, and a file transferring means 8 for transmitting and receiving the files. The host device 9 is composed of a mail file decoding means 11 for decoding the contents of the mail file transmitted from the terminal device 4, a file synthesizing means 12, a file disassembling means 13, a file transfer means 14 and an exclusive control means 15. Input / output means 10 on the host side
Equipped with.

Next, the operation of this embodiment will be described with reference to FIG.

First, by operating the keyboard 1 by the operator, in the case of transmission (step 101), in the case of regular work, the parameter file 2 is created and registered in advance in the format of FIG. 3 and input. As a result, a file is read from the input / output unit 3 based on the information of the file name, medium name, and device name of the transmission source information, and the file combining unit 6 combines them into one file in the format of FIG. 5 (step 102).
This process is repeated until the parameter file 2 is finished, and is combined into one file.

The terminal ID of FIG. 5 is set to the terminal ID registered in advance in the input / output means 3, the header is set to the destination information of the parameter file 2, and the data is read from the input / output means 3. Set the contents of the file. The delimiter sign is determined as a set of one file in the files synthesized by continuing the same character (code not used in the system) for two bytes. In addition, in the case of non-regular work, from the keyboard 1
By inputting the transmission source information and the transmission destination information shown in, and creating a parameter file, the same processing as the routine work can be performed.

The combined file is once written in the work of the input / output means 3 and is transferred to the host by the file transfer means 8 with the input (step 103). The transferred file is written in the work of the input / output means 10 (step 104), and the file decomposing means 13 takes it as an input and decomposes up to the delimiter sign (step 105), and then the medium name and device name of the header part. The file name of the header is written to the input / output unit 10 at the position indicated by (step 106). This process is step 104.
Repeat until the file written in the work becomes EOF (End Off File).

Next, in the case of reception (step 101),
In the case of regular work, the parameter file 2 is created and registered in advance in the format shown in FIG. 3, and the mail file creating means 5 creates a mail file in the format shown in FIG. 4 with the input (step 107). The mail file is a file in which a terminal ID registered in advance is set at the head of the parameter file 2 and is created separately from the parameter file 2. In the case of non-regular business, the same processing as the regular business can be performed by inputting the transmission source information and the transmission destination information shown in FIG. 3 from the keyboard 1 and creating a parameter file. The mail file created in the input / output unit 3 is transmitted to the host device 9 by the file transfer unit 8 (step 108).

The mail file transferred to the host device 9 is written in the work of the input / output means 10 (step 10
9), the input and output means 1 based on the sender information of the mail file by the mail file decoding means 11 with the input
The file is read from 0 and is combined into one file by the file combining means 12 in the format of FIG. 5 (step 11).
0). This process is repeated until the end of the mail file. The terminal ID of FIG. 5 is the terminal ID of the mail file, and the header is the destination information of the mail file.
The data is the contents of the file read from the input / output means 10, and the delimiter sign is made up of 2 bytes of the same character (code not used in the system).

The combined file written in the input / output means 10 is transmitted to the terminal device 4 by the file transfer means 14 (step 111). The combined file received by the terminal device 4 is written in the input / output means 3 (step 112), and the file decomposition means 7 receives it as an input.
As a result, as in the case of the above-mentioned transmission, the data part is sequentially read according to the information of the header part shown in FIG. 5 and written in the input / output means 3 (step 114). This is repeated until the combined file written in the input / output unit 3 becomes EOF.

The exclusive control means 15 performs exclusive control in file units at the time of reading and writing in the input / output means 10.

[0017]

As described above, according to the present invention,
Multiple files can be transferred at once, and by registering the file name to be transferred in the parameter file in case of regular work, it is not necessary to be aware of each file to be transferred, and the operator can confirm the start and end of file transfer. It is sufficient to reduce the burden on the operator and also to shorten the transfer time.
