The beginning of two-section last bit blank line data, charged with spot patch it is whole, and will supplement complete data be filled into third segmentation just
Until data all identify completion in beginning blank line；
Step 23 enters in step 3, transmits to segment data；
Step 3, transmission data.
According to an aspect of the present invention, after carrying out segment identification to data, when re-starting Data Integration,
Data Matching can be carried out according to the data last bit row and data initial row of different segmentations, when data are overlapped, be identified
With completion, it can be eliminated and mutually be gone together, directly progress data recombination.
A kind of character determines data cached method, carries out transient data caching to the data transmission of cloud platform, specific to walk
Suddenly it is divided into:
Step 1, to data cached carry out property determination because order length is one kind compared with progress row data sectional, separately
A kind of protectiveness data storage to carry out in system operation because of accidental interruption, former data transmit after being segmented, the latter
Determine the increase of character；
Step 2, to containing determine character caching segment, carry out protectiveness for a long time store, guarantee not because system grasp
Make generation data loss problem, stores again after can retaining character is determined after confirmation data content；Confirm data
Determine it is the data content for needing to delete after content, after the deletion for first carrying out judgement character, then carries out the deletion of data content, protect
Demonstrate,prove the abundance of spatial cache.
According to an aspect of the present invention, specific cloud platform using system to the data processing agreement of spatial cache not
Together, it is segmented into the ISO agreement and custom protocol of default in this method, it is more intelligent to guarantee that data cached content determines
Change.

Transmission system uses following data segment transmission method, in the process of cloud platform data transmission, due to needing to a variety of systems
The data of system carry out parallel transmission simultaneously and need to carry out segment transmissions, in order to keep away when the order of slab is transmitted
Exempt from the confusion for data recombination occur, needs to be identified same data command, guarantee the integrality of data receiver, specific steps
Are as follows:
Step 1 judges the length of order data, using the safe transmission boundary of each system as standard, the order of short byte
It is directly transmitted, is directly entered step 3；The order of slab enters in character mark step, that is, step 2；
Step 2 carries out length segmentation to the order of slab and carries out Data Identification；
Step 21, in addition to first segmentation, using the data space of a unit storage line fewer than maximum safe transmission boundary as mark
Standard carry out data storage, remaining segmentation always using the data space of two unit storage lines fewer than maximum safe transmission boundary as
Standard is transmitted data division；First segmentation retains last bit blank line, remaining segmentation retains initial blank line and last bit is empty
White two row of row, until the byte length of remaining transmission data is just equal to or less than a maximum safe transmission boundary；
Step 22 is identified the end of data of the transmission data of segmentation, the last line second half section of the first segmentation of duplication
Beginning of the data as the first segmentation last bit blank line data, charged with spot patch whole, and complete data will be supplemented and be filled into
In the initial blank line of second segmentation, and so on, the later half segment data of the last line of the second segmentation of duplication is as second point
Section last bit blank line data beginning, charged with spot patch it is whole, and by supplement complete data be filled into third segmentation initial sky
Bai Hangzhong all identifies completion until data；

For, because the protectiveness data storage that accidental interruption carries out, former data transmit after being segmented, the latter carries out in system operation
Determine the increase of character；
Step 2, to containing determine character caching segment, carry out protectiveness for a long time store, guarantee not because system operatio produce
Raw data loss problem, confirmation data content store again after can retaining later character is determined；Confirm data content
Determine it is the data content for needing to delete afterwards, after the deletion for first carrying out judgement character, then carry out the deletion of data content, guarantees slow
Deposit the abundance in space.
7. the control method according to claim 6 based on cloud platform connectivity port control device, which is characterized in that specific
Cloud platform it is different using data processing agreement of the system to spatial cache, be segmented into this method default ISO agreement and
It is more intelligent to guarantee that data cached content determines for custom protocol.
