Electronic documant coordination downloading system and method

Abstract

A method for downloading electronic file coordinately includes submitting file download task to file download device by user terminal, applying file download by file download device actually and then feeding result back to user. The download system used for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to the technical field of Internet file downloading, in particular to a system and method for collaborative downloading of electronic files, which uses embedded computer technology to realize multi-functional, low energy consumption, and unattended Internet file downloading, especially for large file downloads or slow file downloads. Download has unique applications, which involve multi-thread download of files, breakpoint retransmission, unattended, distributed control, P2P file transfer, streaming media download and embedded Linux technology. Background technique [0002] 1. The current file transfer methods mainly include: [0003] 1) Email [0004] 2) FTP (TFTP) file transfer protocol [0005] 3) HTTP file transfer [0006] 4) P2P file transfer [0007] 5) RTSP / MMS streaming media transmission [0008] 2. The above file transfer methods all have different defects: [0009] 1) Email [0010] ·The file size that can be tr...

AI Technical Summary

Problems solved by technology

[0023] RTSP / MMS streaming media files must be downloaded while playing. Whether the download is continuous or not depends entirely on the network conditions and download content at the time. Under the current network environment, it is difficult to achieve continuous playback. Intermittent playback directly affects the user's understanding of RTSP. Interest in / MMS programs;

[0024] ·Because of the problem of network bandwidth, it takes much longer for users to appreciate RTSP / MMS programs than the program itself;

[0025] RTSP / MMS often inserts advertisements or pops up webpages in the media protocol during playback, which has a very adverse impact on the user's system security. If the popped up webpage points to a malicious webpage, the consequences may be very serious serious;

[0026] 3. Among the existing implementations of the above transmission methods, all of them are implemented by computer software and must rely on the computer system used, so there are some common defects:

[0034] 2) High energy consumption

[0039] 3) High electromagnetic radiation

[0046] 4) There are potential safety hazards

[0052] The computer has many mechanical parts, such as system fan, CPU fan, graphics card fan, power supply fan, optical drive, hard disk, etc., which are easy to be damaged during continuous operation, and are prone to failure after long-term operation;

[0053] Due to the increased power of the computer, the heat generated by the system is relatively large, which has a relatively large impact on the stability of electronic products, ranging from system crashes to permanent hardware damage;

[0054] 5) Inconvenient to use

[0057] The download function cannot be executed through smart terminals such as handheld computers and smart phones

[0058] 6) Invisibly shorten the service life of computer hardware equipment

[0059] Long-term file transfers cause computer hardware to work continuously for a long time, which directly leads to a reduction in computing usage time
