Description
Technical field
The present invention relates to file transfer technology field, specially a kind of file speedy delivery method.
Background technology
The file of embedded system mainly uses FTP now；But File Transfer Protocol needs to enter based on Transmission Control Protocol
Row transmission, higher is required to Embedded Application, using more in implantation Linux embedded scheme, to nothing can not be applied to
Operating system is implanted into the embedded scheme of simple operations system using more difficult；FTP is designed based on TCP, makes it
The embedded scheme without network or WIFI interface can not be applied to, and transplanting Transmission Control Protocol is also needed in transplanting, add its transplanting
Difficulty；FTP and TCP requires higher to system resource simultaneously, and minimum TCP protocol stack needs more than 64K internal memories, makes it can not be
Applied in small embedded systems project.
The content of the invention
It is an object of the invention to provide a kind of file speedy delivery method, is asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the present invention provides following technical scheme：A kind of file speedy delivery method, including lower style of writing
Part transmits and the transmission of up file, wherein, descending file transmission comprises the following steps：
A, descending file transmission start：Server issues 0x8060 instructions, file name that annunciator needs to transmit, big
Small to wait constituent instruments information, whether equipment creates corresponding file, and allow file to transmit to server response；
B, descending scarce bag mends biography mechanism：After startup file transmission, equipment detection local file integrality, missing data is counted
Bag；Instruct notification server current device to lack those packets by 0x0602, server after 0x0602 instructions are received,
Sequentially file data bag 0x8060 is sent to equipment；Server is not to wait for equipment response in the process, with most block speed to setting
Preparation send file data bag, substantially increases transmission speed；When equipment receives last bag of 0x0602 or waits to be received
After 0x8060 time-out, local file is most counted again, if missing data bag, then sends 0x0602 to server again, such as
Fruit is transmitted without missing packet documentary evidence；
C, downstream state reports mechanism：Equipment is starting, file transmit, the individual stage such as is being transmitted and can sent to server
Present transmission state 0x0603 is instructed.
Preferably, up file transmission comprises the following steps：
A, up file transmission start：When equipment is needed to server transport file, send 0x0604 to server and refer to
Order, notification server need to transmit the transmission of the constituent instruments such as title, the size of file；
B, up missing data bag, which is mended, passes：Equipment default server lacks all packets after startup, and to by forward taking
Business device transmits all missing data bags；After all packets are transmitted, device-to-server sends 0x0609 instructions, inquiry
Which packet server lacks；After receiving missing data the package list 0x80609 that server is sent to equipment, equipment is again
Packet sequentially is sent to server, until the 0x80609 missing data reports list that server is sent to equipment is sky；
C, uplink state reports mechanism：Equipment is starting, file transmit, the individual stage such as is being transmitted and can sent to server
Present transmission state 0x0605 is instructed.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention can be provided for embedded OS it is simple,
Stable, quick file transfer mode provides support；The present invention is applied to without operating system application, simple operations system and Linux
System, it is widely used；The transmission method of the present invention data receiver, data in programming, which are sent, uses function pointer mode
Equipment is carried out, it is gone for any character type coffret, such as：RS232, RS485, network etc.；File is read, file
Write-in also uses such a mode, it is gone for the equipment of no file system, is read using simple realization file is only needed
This transmission means can be used in write-in；The transmission means of the question-response of this transmission means abandoning tradition character communication simultaneously, is used
Once ask more bag transmission means to be designed, reduce the stand-by period in answering, reach the maximization of efficiency of transmission.
Embodiment
The technical scheme in the embodiment of the present invention is clearly and completely described below, it is clear that described embodiment
Only part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the common skill in this area
The every other embodiment that art personnel are obtained under the premise of creative work is not made, belong to the model that the present invention protects
Enclose.
The present invention provides following technical scheme：A kind of file speedy delivery method, including the transmission of descending file and upper style of writing
Part transmits, wherein, descending file transmission comprises the following steps：
A, descending file transmission start：Server issues 0x8060 instructions, file name that annunciator needs to transmit, big
Small to wait constituent instruments information, whether equipment creates corresponding file, and allow file to transmit to server response；
B, descending scarce bag mends biography mechanism：After startup file transmission, equipment detection local file integrality, missing data is counted
Bag；Instruct notification server current device to lack those packets by 0x0602, server after 0x0602 instructions are received,
Sequentially file data bag 0x8060 is sent to equipment；Server is not to wait for equipment response in the process, with most block speed to setting
Preparation send file data bag, substantially increases transmission speed；When equipment receives last bag of 0x0602 or waits to be received
After 0x8060 time-out, local file is most counted again, if missing data bag, then sends 0x0602 to server again, such as
Fruit is transmitted without missing packet documentary evidence；
C, downstream state reports mechanism：Equipment is starting, file transmit, the individual stage such as is being transmitted and can sent to server
Present transmission state 0x0603 is instructed.
In the present invention, up file transmission comprises the following steps：
