Problems solved by technology
However, in special working environments such as shipping and oil drilling, there are still weak network restrictions, that is, the network is intermittent and the network speed is not up to standard for a long time
This weak network limitation makes it impossible to carry out reliable data coordination between the sender and receiver of information systems distributed under weak network conditions

The invention provides a data stream cooperative system under the weak network condition. The system comprises multiple sending ends, multiple receiving ends and a cloud storage, acquisition units ofthe sending ends acquire operating instructions of processing units and operation data corresponding to the operating instructions to a database; conversion units convert the operating instructions and the data corresponding to the operating instructions into to-be-sent serialized data, and the to-be-sent serialized data is transmitted to the sending end pushing units which are used for receivingthe to-be-sent serialized data and pushing the to-be-sent serialized data to the cloud storage in a timing cycle mode; the cloud storage receives serialized data and stores the serialized data; the receiving end extraction units extract the serialized data from the cloud storage regularly and judges whether the serialized data is damaged or not according to digital fingerprint value; parsing unisparse the serialized data and store the serialized data to the database. Accordingly, on the condition that the network condition is poor, a weak network barrier is bypassed, data cooperation is completed, and the weak network information isolated island problem is solved.
Description
technical field [0001] The invention relates to the field of ship data, in particular to a data flow coordination system under weak network conditions. Background technique [0002] With the development of network technology, the application of network in all walks of life is becoming more and more extensive. At present, within the scope of the city, the network situation has been able to be well qualified for the interconnection and intercommunication between information systems. However, in special working environments such as shipping and oil drilling, there are still weak network restrictions, that is, the network is intermittent and the network speed is not up to the standard for a long time. This kind of weak network limitation makes it impossible to carry out reliable data coordination between the sending end and the receiving end of the information system distributed under weak network conditions. Contents of the invention [0003] The invention provides a data f...
