6results about How to "Reduce sync delay" patented technology

The application discloses a MongoDB dual-master synchronization method and system supporting field-level concurrent writing, and relates to the technical field of data synchronization of distributed databases. The method listens to change events of a local MongoDB cluster and writes the change events into a local Kafka; synchronizes change events of a remote Kafka to the local Kafka, consumes the change events of the remote Kafka; maintains a field-level version information set; consumes the change events in the local Kafka and queries the latest operation version related to the change events in the field-level version information set; compares the latest operation version with the version number of the change events, and if the version number of the change events is less than or equal to the version number of the latest operation version, determines that it is an abnormal operation and executes rollback correction. The method realizes field-level eventual consistency transparent to business, supports free concurrent writing at any point of dual clusters and does not lose non-conflict field updates, and at the same time, guarantees low synchronization delay and high reliable disaster recovery capability in an efficient and lightweight manner.

The invention provides a warehouse material arrival consistency verification method and system, and belongs to the technical field of intelligent warehousing, and the method comprises the steps that a robot upper computer issues an arrival verification task to a WMS through an interface, receives a standard image, a nameplate field template and technical parameters returned by the WMS, and caches the standard image, the nameplate field template and the technical parameters to the local; the robot carries out image acquisition around the arrival material, positions a nameplate area from an image and carries out image preprocessing, and nameplate text information is extracted through an OCR mode; the robot upper computer extracts a material appearance feature vector from a collected arrival material image, extracts a nameplate region feature vector from nameplate text information, calculates an image similarity score and a text consistency score, fuses the scores, generates a comprehensive confidence coefficient, and generates a verification conclusion according to a comparison result of the comprehensive confidence coefficient and a preset threshold value. According to the invention, full-process automatic verification of the storage materials is realized, the single-piece verification time is shortened, the false identification rate is low, the inventory is synchronously updated, and the storage tracing requirement is met.

This invention provides a cross-terminal collaborative editing system for a digital design platform for woven products, relating to the field of data processing. The system includes: generating and broadcasting semantic summaries of suspended intentions on each terminal to preserve historical data by recording and accumulating influence trajectories in parallel; determining and issuing structural changes in a single step within a delay window based on tension compatibility, replacing gradual merging; sealing breakage features at connection breaks and releasing residual energy in priority order to trigger micro-rearrangement; generating transferable history seeds based on minimum topological closure and recombination primitives to support local compatibility and synthesis; implementing retrospective freezing for suspected unstable changes and unsealing and repairing them upon detection of complementary events or triggering according to rules; and forming a nonlinear self-reinforcing collaborative editing closed loop through cyclical feedback of time and energy.
