Special education network and electronic terminal

Abstract

The invention relates to a network and an electronic terminal special for education, which comprises a network terminal device, a server facility and a network connection device, wherein, the network terminal device is connected with the server facility and interconnected by the network connection device; the server facility is used for conserving the content of mostly all or all textbooks used by students every semester in one or more media formats; the network terminal device is used for downloading the content of mostly all or all textbooks used in every semester from the server facility by the network connection device and then transmitting the downloaded content to the U disk with a large volume for conservation through the USB interfaces on the network terminal device, or uploading various data to the server facility through the network connection device, or being operated by students and teachers in class to show the in-class textbook content for learning the course, or being operated in class to show the content of examination papers for answering the examination papers.

Description

technical field [0001] The invention relates to a network and its terminal facilities, in particular to a network and an electronic terminal suitable for education. Background technique [0002] At present, the schoolbags carried by students, especially primary and middle school students, are too heavy. According to statistics, the schoolbags of middle school students generally weigh about 20-30 kg. On the one hand, because of the sudden increase in the content of students' learning, the overall weight of textbooks is much heavier than its previous weight; this is extremely unfavorable for the healthy development of growing teenagers. And, also more and more consume country's a large amount of forest timber resources. [0003] Now, some companies are developing electronic school bags, which store all the books used by students in the form of e-books, hoping to use it to replace the current very heavy school bags for students and reduce the consumption of forest resources. ...

Problems solved by technology

[0008] Chinese utility model patent CN01253035.2 discloses a distance education terminal, although it can provide convenient and cheap real-time interactive means for distance education, but there are some shortcomings in this terminal: (1) the terminal facility is only used for students and teachers classroom exercises and exams, so the display only displays prompt information and test questions, and does not consider using them to display the contents of student textbooks; (2) the keys on the keyboard are only used for operations such as login, attendance, speaking, answering questions and submitting answers, etc. Consider the operation of students' classroom notes and the school's computer course education; (3) using external RAM to store test paper or answer result data will increase the terminal cost; (4) the voice module circuit and monitoring circuit (watchdog) in the terminal circuit are both compatible with The single-chip microcomputer is separated, so the circuit integration and reliability are low, and the circuit cost is also high

It can be seen that this distance education terminal is deficient both in terms of performance, circuit reliability and cost.
