Description

Description: TECHNICAL FIELD The present invention relates to a network type education system, and more particularly to a network type education system using a computer in a company or a school.

2. Description of the Related Art Conventionally, in a network type education system,
As shown in the figure, a plurality of workstations 3-i (i
= 1, 2,...) Are connected via a LAN (Local Area Network) 100 to the file server 2 storing the teaching materials 20 and the learning data 21, and each workstation 3-i is connected to a virtual drive (B: ) 32-i stores the data of the teaching material 20 of the file server 2 as if it were a local drive (A :) 31-i.
It can be read out and learned as if it were on the top.

Generally, the reading of data from the teaching material 20 of the file server 2 and the input / output to / from the learning execution process 33-i and the personal computer (hereinafter referred to as a personal computer) 30-i are performed sequentially.

During the learning, the virtual drive of the file server 2 is
In the method in which the access to the 32-i is performed every time, the processing speed of the learning execution process 33-i may be reduced due to competition on the LAN 100. In many cases, a download method for batch transfer of the teaching materials 20 of the server 2 is used.

In such a conventional network type education system,
Since each workstation 3-i transmits and receives data via the LAN 100 each time it needs data from the file server 2, it is possible to transmit and receive necessary data in advance in parallel with the learning execution process. There is a problem that it is difficult.

Further, since the plurality of workstations 3-i are connected to the file server 2 via the LAN 100, contention for access to the file server 2 occurs, data transmission / reception becomes extremely slow, and the learning execution process 33-i is performed. There is a problem that the processing speed of i decreases.

Furthermore, in the case of the download method in which the data of the teaching materials 20 of the file server 2 is transferred in a batch, it takes time to transfer the data of the teaching materials 20 of the file server 2 before the learning starts.
There is a problem that learning cannot be started immediately.

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate the above-mentioned problems of the related art, and necessary data can be transmitted and received in advance in parallel with the learning execution process, and contention with the file server occurs. It is an object of the present invention to provide a network-type education system that can start learning immediately without lowering the processing speed of the learning execution process and can improve operation efficiency.

A network-type education system according to the present invention connects a file server that stores learning data and a plurality of learning terminal devices each including a storage unit that stores the learning data read from the file server via a network. A pre-reading unit that pre-reads the learning data from the file server in a preset order and stores the learning data in the storage unit, and manages information of storing the learning data in the storage unit. When it is necessary to read out the learning data from the file server in accordance with the progress of the learning, the management table is referred to. The learning data from the management table A learning execution unit that reads out the learning data from the file server and executes learning when the learning data of interest is not present in the storage unit according to a reference result, in each of the plurality of learning terminal devices; Utilizes the idle time of the learning terminal device due to waiting for a reaction input during the execution of learning by the learning executing means, and prefetches a file on a file server by background processing and writes it in the storage means as needed. It is characterized by.

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

FIG. 1 is a block diagram showing the configuration of one embodiment of the present invention. In the figure, a workstation 1 is a virtual drive (B :) 12 of a file server 2 and its virtual drive 12
The file on the file server 2 can be read at any time via the LAN 100 by the disk cache 13.

The file read-ahead task 14 reads necessary files from the file server 2 by the virtual drive 12 and writes them to the local drive (A :) 11 by background processing during learning execution, and the necessary files exist in the local drive 11. This is stored in the file read management table 15.

Here, learning data 21 for each learning material in the list of learning materials 20 of the file server 2 displayed on the display screen of the personal computer (hereinafter referred to as a personal computer) 10 when performing learning is arranged in a predetermined order. Since it is stored in the file server 2, the file prefetching task 14
Are sequentially read from the file server 2 as learning data files necessary for the teaching material selected from the list.

On the other hand, when the learning execution task 16 needs to read a file from the file server 2 by the virtual drive 12 in accordance with the learning progress, first, the file reading management table 15
To confirm whether the corresponding file has been written to the local drive 11 or not.

If the relevant file has been written to the local drive 11, the learning execution task 16 reads the file from the local drive 11 and continues learning.

If the corresponding file has not been written to the local drive 11, the learning execution task 16 reads the file from the file server 2 by the virtual drive 12 and continues learning.

During the learning process, the PC 10 is often in a waiting state because the learner reads the display screen of the PC 10 or waits for a response input to answer a question on the display screen. The task 14 is executed efficiently using the waiting time (vacant time) of the personal computer 10.

As described above, the file on the file server 2 is prefetched and written to the local drive 11 at any time by the background processing by the file prefetching task 14 using the idle time of the personal computer 10 due to the response input of the learner. By doing so, necessary files can be transmitted and received in advance in parallel with the learning execution process, and a decrease in the processing speed of the learning execution process due to competition on the LAN 100 can be prevented.

In addition, since it is not necessary to transfer all the teaching material files as in the download method in which the teaching materials are batch-transferred before the start of the learning, the learning can be started immediately and the operation efficiency can be improved.

Effect of the Invention As described above, according to the present invention, a file on a file server is read in advance in a background process by using the idle time of a learning terminal device due to a response input of a learner and written to a local drive as needed. By doing so, necessary data can be transmitted and received in advance in parallel with the learning execution process, and even if a conflict with the file server occurs, the processing speed of the learning execution process is not reduced, There is an effect that the learning can be started immediately and the operation efficiency can be improved.
