This invention relates to the field of smart meter communication data acquisition technology, and discloses a method for anti-interference data acquisition in smart meter communication based on multi-carrier modulation technology. The method includes using multi-carrier modulation to perform frequency division processing on the signal during data transmission, combining channel state perception and dynamic subcarrier allocation strategies to avoid interference frequency bands in real time, and enhancing data robustness through time-frequency joint coding. This application can effectively suppress narrowband interference and impulse noise, improving the communication reliability and data acquisition accuracy of smart meters in complex electromagnetic environments.

The present application relates to the field of coating parameter self-optimization, and discloses a coating process parameter self-optimization system and method fusing model self-learning, wherein a coating process parameter self-optimization method fusing model self-learning comprises the following steps: collecting process parameters, production conditions, equipment power states and detection result data of multiple batches of coating production in real time; aligning and correlating the data according to the process sequence to form a unique mapping relationship; reversely determining corresponding process parameter nodes and working condition node sets to generate a consistency index; jointly comparing the consistency index and the corresponding data chain distribution to output corresponding working condition drift identifiers; introducing the consistency index and the working condition drift identifiers as constraint conditions into a parameter update model to output a constrained parameter update result; and writing the corresponding new round of detection results into the unique mapping relationship to generate an incremental updated mapping relationship and a reachable state space. The present application has the advantage of improving the stability of the optimization result.

The method comprises the following steps: receiving and verifying data source configuration information through a configuration interface, and registering the data source configuration information to a unified registration center for state management; defining a standardized adapter interface, configuring corresponding adapters for different types of data sources, and registering the adapters to a center for dynamic loading of a service module; the service module subscribes to registration center change information, dynamically discovers available data sources and loads corresponding adapters to establish connection; reading data of the data source through an adapter and converting the data into a unified intermediate format; and automatically scheduling a data access task through a task scheduling framework, and monitoring and alarming an execution process. Through the unified registration center and standardized pluggable adapter architecture, agile access, dynamic maintenance and automatic management of the data source are realized, and the data integration efficiency, the system elasticity and the maintainability are remarkably improved.

The application discloses a SQL statement template dynamic updating method and device, equipment and storage medium, relates to the field of databases, and comprises the following steps: constructing a to-be-matched template sequence of a to-be-processed SQL statement; determining the longest common subsequence between each statement template sequence and the to-be-matched template sequence, determining a target statement template sequence from all statement template sequences based on all the longest common subsequences; if the sequence length of the longest common subsequence corresponding to the target statement template sequence is greater than or equal to a preset sequence length threshold, updating the target statement template sequence to the corresponding longest common subsequence in a dynamic statement template sequence library; and if the sequence length of the longest common subsequence corresponding to the target statement template sequence is less than the preset sequence length threshold, adding the to-be-matched template sequence to the dynamic statement template sequence library as a new statement template sequence. The application realizes updating of the dynamic statement template sequence library of the SQL statement.
