Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file downloading method for downloading files having the same contents to a plurality of terminals on a network.

[0002]

2. Description of the Related Art Files used in workstations (including binary files such as modules) are created by using a personal computer or the like, for example, in C language. The created file needs to be loaded into each of several tens to several hundreds of personal computer terminals (hereinafter, referred to as “PC terminal”) connected to the network.

Conventionally, a file developed and created by a PC terminal is stored in a floppy disk once, and then the floppy disk is brought to a PC terminal distributed over the network, and the file is stored in the storage device of the PC terminal. Installed on the specified disk etc. This installation work is performed for all PC terminals.

[0004]

However, in the above-mentioned prior art, since the floppy disk storing the created file is brought to each of the PC terminals to be installed, the PC terminals are installed. When the number is large, it takes a lot of time to finish the work, and there is a problem that the work efficiency is poor. In addition, since the installation cannot be performed for each PC terminal at the same time, there is also a problem that the systems of the PC terminals distributed on the network cannot be synchronized.

It is an object of the present invention to provide a file download method for terminals sharing a transmission path that makes it unnecessary to install files on the respective computer terminals and synchronizes with each other.

[0006]

In order to achieve the above object, the present invention provides a network in which a plurality of computer terminals and a server are connected to a shared transmission line, and one of the terminals or an external terminal is provided. After the file developed or created by using the device is uploaded to one of the computer terminals connected to the network and written in the log, the file is downloaded from this server to each computer terminal and the log is recorded at the same time. I try to write. The download from the server to each of the computer terminals is executed when the date set by the server is newer than the date in the download execution file on the computer terminal side.

[0007]

According to the above-mentioned means, the developed or created file is once uploaded to the server on the network through one computer terminal, and then downloaded from the server to each computer terminal. , Is installed on each computer terminal. This eliminates the need for manual installation work by bringing a floppy disk to a computer terminal. Also, system synchronization between computer terminals can be achieved.

Furthermore, by setting the date to be downloaded in the server in advance, even if the computer terminal is downloaded on the specified date and the computer terminal is turned off, the power is turned on. If the date set on the server side is newer than the date on the computer terminal side, the download is executed.

As a result, even when the computer terminal is powered off when it is downloaded from the server to the computer terminal, the download is automatically performed when the power is turned on. You can

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

FIG. 1 is a flow chart showing a processing example of a file download method for terminals sharing a transmission line according to the present invention. 2 is a block diagram showing an example of a network system to which the present invention is applied. Note that "S" in FIG. 1 means "step". Further, in the following, in order to simplify the explanation, P
There are only two C terminals.

In FIG. 2, an Ethernet is used as a network, and a plurality of (here, two) PC terminals 2 and 3 are connected in a distributed manner on a transmission line 1 thereof. PC terminal 2, 3
Respectively include hard disk devices 4 and 5 as storage devices. Further, the transmission path 1 is connected to a server (Server) 6 that uses UNIX (Unix) as an OS (Operating System). A hard disk device 7 for storing files is connected to the server 6 (WS).

File down processing in the network system having the above configuration will be described with reference to FIGS. 1 and 2.

First, the upload processing to the server 6 will be described. The file to be downloaded to the PC terminal side in advance is copied to the designated directory (S10
1) (route in FIG. 2). As is well known, UNI
In X, a user can create a directory so that file management can be easily performed, and a plurality of files related to the directory can be collected.

Next, in order to upload the file from the PC terminal side to the server 6, NFS (Network) is used.
The server 6 is mounted using File System (S102). Then, the batch file to be uploaded to the server 6 is activated, and the file is copied to the directory designated by the server 6 (S103). At the same time, a log (LOG) about the contents of upload is written (S104). By referring to this log,
You can check whether the file has been copied.

Next, the download process from the server 6 to the PC terminals 2 and 3 will be described. First, the server 6 is set to a date to be downloaded to the PC terminals 2 and 3. The PC terminals 2 and 3 do not always use power for 24 hours. Therefore, when the power is turned on (power is turned on) at the time of starting work, it is determined whether or not the date set in the server 6 is latest than the date on the side of the PC terminals 2 and 3 (S105, 106). ). If the latest date,
The download is automatically started (S107). Simultaneously with this download, the log is written in the PC terminals 2 and 3 (S108). This makes it possible to confirm whether the file has been copied.

In the above embodiment, the transmission line 1 is a bus type. However, the transmission line 1 is not limited to this, and any type such as a star type, a loop type, a ring type and a tree type may be used. You can

Similarly, in the above embodiment, the network is Ethernet, but this is only an example, and the present invention can be applied to any type.

[0019]

Since the present invention is configured as described above, it has the following effects.

In a file download method for a terminal sharing a transmission line according to claim 1, in a network in which a plurality of computer terminals and a server are connected to the sharing transmission line, one of the terminals or an external device. A file developed or created using is uploaded from one of the computer terminals connected to the network to the server and the log is written, and then the file is downloaded from the server to each computer terminal and the log is written at the same time. Therefore, the manual installation work becomes unnecessary, and the personnel cost and work efficiency can be improved. Further, the system can be synchronized between the computer terminals, so that the reliability is improved.

In the file download method for terminals sharing a transmission path according to claim 2, downloading from the server to each of the computer terminals includes:
Since the date set in the server is newer than the date in the download execution file on the computer terminal side, even if the computer terminal is powered off, it is automatically executed when the power is turned on. Since it is downloaded, it can be installed reliably.
