Embodiment 1

[0065] The usage method of video resources in the system of the present invention:

[0066] 1) Book resources are stored in the system as fragmented files;

[0067] 2) The application verifies the resource, uses the directory package, and extracts the characteristic value according to the attribute information;

[0068] 3) Read the number of files in the directory and the total size of the files, combine this information in a fixed format, and perform MD5 calculation on the combined string to obtain a 16-digit MD5 value, which is the check code;

[0069] 4) Compare the calculated check code with the check code in the system resource properties. If they match, it proves that the resource is correct; otherwise, it fails to open;

[0070] 5) Extract the usage count in the resource attribute. When the count is greater than 1, the user is prompted to use the resource and save the count by one; when it is zero, the user will not be able to open the file for use; when the count is m...

Embodiment 2

[0072] Application method in the system of the present invention:

[0073] 1) The application program in the system is written into the system once and installed when the handheld terminal is initialized;

[0074] 2) After the application in the system is installed, the initialization tool extracts the application signature;

[0075] 3) Extract 50 bytes backward from the beginning of the file, extract 50 bytes from the middle of the file, and extract 50 bytes forward from the end of the file;

[0076] 4) According to the extraction order, combine the extracted content, perform MD5 operation on the combined string, and get 16 as the MD5 value, which is the check code;

[0077] 5) Record the calculated check code in the specified file of the system;

[0078] 6) Before opening the application for use, the user extracts the verification code according to steps 3) and 4). If they are consistent, the application is opened, otherwise the opening fails.

Embodiment 3

[0080] The method for system self-test of the present invention:

[0081] 1) The system automatically runs the only desktop program after booting and running, and starts the detection thread at the same time;

[0082] 2) Firstly, check the completeness of the system files of the handheld terminal;

[0083] 3) For independent large files, use multi-point combination verification to extract feature values, extract 50 bytes backward from the beginning of the file, extract 50 bytes from the middle of the file, and extract 50 bytes forward from the end of the file, according to the order of extraction , combine the extracted content, perform MD5 operation on the combined string, and get 16-bit MD5 value, which is the check code;

[0084] 4) For scattered files, use the method of packaging and extracting feature values ​​in a unified manner, read the number of files in the directory, the total size of the files, combine this information in a fixed format, and perform MD5 operations...

Abstract

The invention discloses a mobile learning system and a using method thereof. The system comprises a handheld terminal, a data synchronization terminal and a server, wherein the handheld terminal is interconnected with the data synchronization terminal and is used for using resources and checking the resources, programs and the system; the data synchronization terminal is also interconnected with the server and is used for uploading data, downloading the resources and caching different files; and the server is used for executing authority control, resource subscription and resource retrieval. By the mobile learning system, the problem that the conventional handheld terminal in the market is not secure when used in some specific environments is solved, the resource loading efficiency is improved, so that a user can fully use the modern information technology, and a self-learning environment in which the user can take along with the system to learn at any time and any where can be realized.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a mobile learning system and a usage method. Background technique [0002] With the rapid development of mobile computing technology, mobile learning, a digital learning method with the characteristics of interaction anytime and anywhere implemented by using mobile communication technology, has emerged. Mobile learning is developed on the basis of digital learning. Compared with digital learning, mobile learning not only has the characteristics of digitization, multimedia, networking, and intelligence, but also has its unique advantages: learners no longer Limited by the fixed site based on the desktop computer, learning can be carried out "anytime, anywhere, and with you" in a "short, flat, and fast" manner. The technical basis of mobile learning is mobile computing technology and Internet technology, that is, mobile Internet technology, and the tool for re...
