The application provides an error self-calibration method and an ultrasonic water meter, and relates to the technical field of intelligent water meters.The error self-calibration method comprises the following steps: a flow opening degree model is configured in a to-be-calibrated ultrasonic water meter; current first water consumption data of the to-be-calibrated ultrasonic water meter are obtained; a current theoretical instantaneous flow is determined by using the flow opening degree model according to water pressure in a pipe section and a valve opening degree; a deviation value of the theoretical instantaneous flow and an actual instantaneous flow is calculated, and a calibration mechanism is triggered when the deviation value is greater than a first deviation threshold; after the calibration mechanism is triggered, second water consumption data of the to-be-calibrated ultrasonic water meter under a plurality of different valve opening degrees are obtained; self-test model coefficients of the flow opening degree model are calculated according to the second water consumption data; the self-test model coefficients and original model coefficients are compared, and the original model coefficients are corrected according to comparison results of the model coefficients, so that self-calibration of the flow opening degree model is realized.The application can improve real-time performance and accuracy of calibration of the ultrasonic water meter.

This application provides a method, apparatus, electronic device, and storage medium for predicting battery heat generation power. It acquires multiple first average heat generation powers of the battery when charged and discharged at different rates at a target temperature, and multiple second average heat generation powers of the battery when charged and discharged at the target rate at different temperatures. The target temperature includes the middle temperature of the battery's operating temperature range, and the target rate includes the rate at the middle position of the battery's rate range and the rate at the beginning and / or end positions. The multiple first average heat generation powers and multiple second average heat generation powers are fitted to obtain a relationship between the heat generation power of the battery when charged and discharged at different rates at different temperatures. Based on the obtained heat generation power relationship, the heat generation power of the battery when charged and discharged at any rate at any temperature is determined. This application can save testing time and resources while ensuring prediction accuracy.

The application discloses an anti-data-damage heterogeneous federated learning system and method, which first adopts a robust data enhancement strategy in the local update stage, minimizes the adverse effects of local damage by performing multiple random data enhancement operations, and enables the model to learn rich local knowledge. Secondly, a robust reweighting communication method is designed in the collaborative update stage, which realizes communication between heterogeneous models while reducing the damaged knowledge obtained from other models. Finally, for the damaged feedback of unreliable clients, the application minimizes the learning of damaged knowledge by dynamically adjusting the contribution of the clients. The application achieves this goal by using a public data enhancement strategy that dynamically adjusts the contribution of the clients according to their ability to cope with data damage. The application can significantly improve the robustness to various data damage, thereby improving the performance of model heterogeneous federated learning.

The application relates to an FTP unstructured file transmission breakpoint continuation implementation method and device based on DataX. The method comprises the following steps: integrating a progress tracking module into a DataX Writer, creating a transmission progress metadata file (TPMF) containing information such as the number of uploaded bytes and the state for each file and dynamically updating; deploying an independent process monitor to monitor task interruption and trigger progress persistence to the TPFM; a user selects a file through an independent FTP continuation scheduler, reads the TPFM and the server-side target file size to determine the breakpoint, calls an FTP REST command to continue from the breakpoint, updates the state after completion, and the like. The method realizes accurate progress recording, active saving in abnormal interruption and user-controllable continuation, avoids redundant retransmission, improves transmission efficiency and resource utilization, enhances data synchronization robustness and reduces operation and maintenance complexity. The method has small invasiveness to the DataX core, is strong in universality and is suitable for high-reliability synchronization scenes of large-scale unstructured files.
