Keyword SD learning card manufacture method

Abstract

The invention discloses a keyword SD learning card manufacture method. The method is characterized by generating data file composed of learning information SN, learning terminal device SN, user SN, and order ID and saving HASH values 2 in a database corresponding to a SD card and a learning terminal device; comparing the HASH values 2 on the SD card and the learning terminal device; after successful decoding decrypting non-video-audio learning information and an application program and copying all files into the SD card; and the SD card is completed after a step S801 and can be normally used. A step S701 and a step S702 are required before the SD card is replaced every time. The method guarantees one card, one machine, one order, one user, and one piece of information, and guarantees the valid benefit of a curriculum developer and a learner.

Description

technical field [0001] The invention relates to the field of making SD learning cards, in particular to the field of designing SD learning cards based on a keyword learning method and capable of communicating with a multifunctional card-type point-touch learning machine. Background technique [0002] Electronic learning machines have been widely used in various teaching and teaching aids, and are currently a popular learning tool. However, since the current electronic learning machines are generally in an electronic state, the update of their learning resources is more complicated, or even impossible, and they have become disposable school supplies without compromise, which is not conducive to the repeated use of resources. [0003] With the continuous development of social science and technology, there are also learning machines based on operating systems such as Android, which solve the problem of updating learning resources to a certain extent, but because their updates a...

Problems solved by technology

Although the former saves costs, most of its learning courses are updated for free, so developers are not very motivated. Although the latter takes care of the enthusiasm of course developers, it needs to replace the entire learning machine in the face of new courses. , the cost paid by learners is extremely high

[0010] In response to this, there are currently some learning machines that are updated and sold in the form of learning cards, but due to the small capacity of learning cards or poor confidentiality, it is not conducive to large-scale promotion
