The invention discloses a motor train distributed big data transmission optimization method which is applied to a motor train unit management information system comprising an iron total center node, a plurality of segment-level intermediate nodes connected to the iron total center node and a plurality of level nodes. Comprising a data source set generation step, a database load monitoring step, a weight optimization iteration step and a data transmission optimization step. And dynamically adjusting the transmission sequence of the selected data sources based on the weight value of each selected data source, optimizing the data load of each sub-period, and repeatedly carrying out weight optimization iteration until the optimized data load meets the optimal load principle, thereby realizing peak clipping and valley filling of the data load of each sub-period. And optimal transmission of distributed big data is satisfied. The method provided by the invention effectively solves the problem of data transmission congestion caused by unbalanced data transmission in a one-to-many centralized transmission topological structure. The invention further discloses a bullet train distributed big data transmission optimization system, equipment and a medium.
Description
technical field [0001] The present application relates to distributed data transmission management, and in particular, to an optimization method, system, device and medium for distributed big data transmission of motor vehicles. Background technique [0002] At present, the transmission of big data plays an increasingly important role in various distributed systems. Whether the function of the distributed system is realized, whether the performance meets the standard, and whether the failure rate is lower than the allowable value depends to a large extent on the efficient, accurate and reliable transmission of data. [0003] However, the data sources of distributed systems are often cross-regional, cross-platform, complex in composition, and often very uneven in time distribution. Often in a certain period of time or a certain section, a large amount of data needs to be transmitted. However, in some other time period or some other section, there is idle time, which leads t...
