4results about How to "Improve data synchronization efficiency" patented technology

This invention provides a data synchronization method and apparatus. Through a visual interface, the data source and target cluster index parameters are configured. A data synchronization task is created based on the data source and index parameters. The task's time period and triggering rules are set. The task is scheduled according to these rules. An incremental watermark algorithm is used to read data from the data source. Write nodes are dynamically allocated based on load. A search interface combining HTTP / Socket dual protocols and local caching is provided to query data for business scenarios. This improves development efficiency, ensures data consistency and reliability, enhances resource utilization, and reduces data synchronization time. It significantly improves the data synchronization efficiency and system stability of distributed systems and is suitable for high-concurrency, multi-source, heterogeneous data synchronization scenarios.

The invention provides a vehicle-mounted data processing method, a vehicle control method and a control system. The vehicle-mounted data processing method comprises the following steps: generating a plurality of target data blocks based on compressed vehicle-mounted data; the first root hash of each target data block is sent to the cloud and registered, and after the target data block is uploaded to the cloud, the registered first root hash is used to carry out integrity verification on the target data block; when the verification fails, recursively comparing the sub-tree Hash based on the first root Hash which fails in verification to obtain an error data unit in the target data block, and performing retransmission processing; integrity verification is carried out again after each retransmission, and the number of retransmission times is provided with an upper limit; and writing the verified target data block into the target storage layer. According to the invention, the bandwidth utilization rate can be obviously improved in a weak network environment, the transmission energy consumption of the edge node is reduced, the transmission and processing speed of the vehicle-mounted data from the vehicle end to the cloud end is accelerated, and the data synchronization efficiency of the whole vehicle networking system is improved.

The application provides a data synchronization method, a storage system, equipment and a storage medium, and relates to the field of storage. The storage system comprises a first computing node, a second computing node and a shared storage device. When the first computing node flushes the obtained primary copy into a data segment in the memory, the first computing node copies a first part of data of the data segment to the second computing node through network transmission, and stores the data segment into the shared storage device when preset storage conditions are met. The second computing node processes and stores the received first part of data, and reads and loads a second part of data of the data segment from the shared storage device when it is determined that the second part of data is not stored. The first part of data and the second part of data are secondary copies of the primary copy. In the technical scheme, in the storage system architecture of separation of computing and storage, the primary and secondary copy synchronization is realized by using two synchronization links of the shared storage device and the network transmission, and the data synchronization efficiency is improved.

The application discloses a kind of trisomy nomadic AI ark full industry chain cloud general control integrated edge platform system, belong to MiC modularization cluster multi-subsystem unified scheduling, edge cloud fusion processing, multi-protocol data intercommunication, travel energy storage carbon asset business cooperation technical field.Each functional subsystem is independently deployed to form data island in the prior art, lacks unified top edge general control hardware carrier, multi-business data cannot be fused to judge, and there is room for improvement in the efficiency of multi-scenario cooperation of industry operation, energy storage transaction and emergency dispatching.The application takes the whole cloud general control edge gateway as the entity bearing, builds seven-layer general control architecture, and standardizes the interface of all bottom hardware subsystems from 1 to 7;Integrates seven cooperative modules of protocol adaptation, data fusion, multi-business analysis, virtual power plant transaction, carbon asset statistics, planning and emergency coordination and industry report, synchronously collects land / sea / air ark full-dimensional operation data in the whole world and generates integrated operation and dispatching strategy.The scheme is suitable for the operation of grassland travel, offshore camp and low-altitude station full industry chain, and the synchronization time delay of cross-system data is reduced to 120 ms, the workload of multi-business artificial comprehensive disposal is reduced by 66%, and the cluster comprehensive operation income is increased by 24%.
