The invention discloses an intelligent networking distributed storage interaction system based on multi-cabin cooperation and a method thereof, and belongs to the technical field of camping intelligent cabin interaction, and the method comprises the following steps: taking each intelligent cabin as an independent node, initializing and accessing an intelligent networking distributed system, and enabling the nodes of the intelligent cabins to establish initial connection with other nodes in the system; each intelligent cabin collects user data, environment data and equipment state data through a built-in sensor and stores the collected data in a local storage unit in a classified mode. According to the method, the data synchronization among the nodes of the intelligent cabin is realized through a distributed database consistency algorithm, the data consistency under the condition of network delay or interruption is ensured, the data conflict and damage are prevented, and the system reliability is improved. Meanwhile, resource allocation is dynamically optimized based on an intelligent scheduling algorithm of machine learning, different load requirements are met, resources are saved, and the system efficiency and the intelligent level are improved.

This application discloses a servo synchronization method, apparatus, mechanism, unit, system, medium, and product. The servo synchronization method is applied to a servo mechanism and includes: receiving model parameters of a virtual spindle model from a control unit; running the virtual spindle model based on a local synchronization clock according to the model parameters; and broadcasting a correction event to other servo mechanisms when the following error between the actual position of the local axis and the theoretical position of the virtual spindle model meets a trigger condition, so that the servo mechanisms that hear the correction event can collaboratively correct the position of the corresponding axis. In this technical solution, the control unit only needs to send model parameters and does not need to continuously control each servo mechanism. Each servo mechanism can run the same virtual spindle model locally based on the model parameters. When necessary, it can broadcast correction events to enable other servo mechanisms to perform collaborative correction, transforming periodic communication into event-triggered communication, reducing communication overhead, and achieving high-precision and efficient synchronization.

The present disclosure provides a key unit synchronization method and related equipment for a structured document. In this method, a web page multithreading tool listens to a first event triggered by a user modifying the first content of a first key field among multiple key fields in a first area, and sends the first identifier of the first key field and the modified first content to a second web page communication tool through a first web page communication tool. The second web page communication tool returns a message including the received first identifier and the modified first content to a pre-specified event handler, so that the event handler determines the first bookmark attribute corresponding to the first identifier among multiple bookmark attributes, and modifies the second content in the first bookmark attribute in the second area according to the modified first content. In this way, the relevant parts of the structured document can be automatically and synchronously modified according to the modification of the content in the database of the business system.

The present invention discloses a method for synchronizing an urban rail transit interconnection operation diagram. The method is based on the rail transit line network operation mode and is applied to the synchronization of the rail transit line network operation diagram and the line operation diagram; the line network plan operation diagram is decomposed into several executable line plan operation diagrams through a decomposition algorithm; different line real-time operation diagrams are merged through a merging algorithm to form a line network real-time operation diagram; the line network daily shift plan operation diagram is decomposed into several line daily shift plan operation diagrams through a decomposition algorithm, and different line daily shift plan operation diagrams are merged through a merging algorithm to form a line network daily shift plan operation diagram. Efficient and convenient synchronization between the line operation diagram and the line network operation diagram is achieved, solving the coordination problem between the global operation diagram of the line network and the single line operation diagram; moreover, it can be applied to the cross-line operation of multiple lines without the need for additional parameter configuration.

The invention discloses a block chain storage optimization method based on transaction aggregation backward consensus, and the method comprises the following steps: S1, forming a digraph for historical transfer transactions in a block chain, delimiting a clearing interval, enabling each node in the block chain to participate in the loop search in the digraph, and taking a node reputation value as excitation, the nodes compete for each other, so that more transaction loops can be found in a shorter time; s2, for a competition result of loop search, a deterministic algorithm is adopted to calculate a loop clearing sequence, and transaction multilateral clearing is carried out on all loops according to the sequence; and S3, performing multiple rounds of clearing in the same interval by using an iterative ring buckling algorithm and a continuous transfer transaction simplification mechanism, and taking a clearing result as an aggregation transaction to replace a transaction before clearing so as to quit a block chain storage space. According to the method, the storage space of the block chain is cancelled under the condition that the final transaction execution result is consistent, the expandability of the block chain is improved, and the transaction processing capability is improved.

The application discloses a database bidirectional data synchronization method, an electronic device and a computer program product, and belongs to the technical field of databases. The method comprises the following steps: generating target hash data based on change data of a first database, and storing the target hash data into a target sending thread of the first database; the target sending thread is any one of a plurality of sending threads in the first database; the target sending thread sends the target hash data to a target receiving thread of a second database; the target receiving thread is a receiving thread corresponding to the target sending thread in a plurality of receiving threads in the second database; the target receiving thread traverses each sending thread in the second database based on the target hash data, checks whether there is a same hash value as the target hash data, and obtains a check result; and performing data synchronization on the second database based on the change data of the first database according to the check result.
