The invention relates to the technical field of testing of parts of low-voltage apparatuses, and discloses a method and a device for testing bimetallic strips of a circuit breaker. The test method for the bimetallic strip of the circuit breaker comprises the following steps: step 10, assembling and fixing a to-be-tested assembly, including assembling and fixing the bimetallic strip, a flexible connection structure, an operating mechanism and a moving contact in a connection mode in the circuit breaker; step 20, connecting the to-be-tested assembly with a test circuit, and obtaining a real-time test posture of the bimetallic strip; and step 30, calculating thermal deformation data of the bimetallic strip according to the test posture and the initial posture. According to the test method for the bimetallic strip of the circuit breaker, the connection relation of the bimetallic strip in the circuit breaker is simulated, the test is carried out in the state, it is guaranteed that thermal deformation data of the test position of the bimetallic strip is consistent with the actual application process, and then the circuit breaker with higher reliability can be obtained.

The invention relates to the field of data processing, and provides a data verification method and device for big data cluster migration, equipment and a medium, the verification method comprises the following steps: newly establishing a target data cluster on an original data cluster, preprocessing the target data cluster, and marking the preprocessed target data cluster to obtain an ODS synchronization task; the method comprises the following steps: identifying an import command in an ODS synchronization task, capturing incremental change table data from an original data cluster by a target data cluster according to an identification result until the data volumes of current storage data of the target data cluster and the original data cluster are the same, and then performing synchronization and merging to obtain two merged tables. According to the embodiment, the data of the two clusters can be kept consistent through the imported incremental change table data, and the problem that migration data are inconsistent is effectively avoided.

This invention discloses a data synchronization method, system, electronic device, and medium for a distributed cluster. The data synchronization method includes: detecting whether all nodes have the same expected update time for the next incremental data update at the current moment; the expected update time is determined based on the moment when the data source performed an incremental data update in the previous moment; for nodes with an expected update time, using the expected update time as the determination time for the node to perform an incremental data update in the next moment; when the current moment reaches the determination time, controlling each node to obtain the latest incremental data from the data source to update the historical data of each node. This invention uses the update time of the data source's next incremental update as the determination time for each node's next data update, ensuring that the update time of each node remains consistent, guaranteeing consistent data updates across all nodes in the distributed cluster, and reducing latency between nodes and the data source.

The present application relates to a terminal device and an upgrade method thereof, the upgrade method comprising: the terminal device is started through the first boot partition based on the first partition table contained in the first partition table space; the system upgrade package is obtained, and the system upgrade includes the second partition table and partition upgrade data corresponding to the target software version; based on the second partition table and the partition upgrade data, the data of the second boot partition and the system partition are updated; based on the second partition table of the second partition table space, the terminal device is started through the second boot partition. Through the above-mentioned upgrade method, the second partition table is stored by setting the second partition table space, so that the system can be restarted after the upgrade by loading the second partition table to complete the upgrade. Even if the system update fails or the system fails to start, the system can be rolled back to normal operation before the upgrade by loading the original main partition table.

Embodiments of the present disclosure provide a data pushing method and device, equipment and a storage medium. The method comprises: obtaining first target data from a data source based on a data subscription request of a business party; pushing the first target data into a message queue of the business party; obtaining second target data from the data source based on the data subscription request; correcting the first target data in the message queue based on the second target data, so that the business party reads the corrected first target data from the message queue. According to the embodiments of the present disclosure, the first target data in the message queue is corrected by the second target data, which can ensure that the data pushed to the business party is consistent with the data in the data source, and improve the accuracy of data pushing.

The invention discloses a rapid screening method of rust-resistant pepper and application thereof, and belongs to the technical field of disease-resistant breeding. The screening method comprises the following steps: taking Chinese prickly ash leaves, preserving the Chinese prickly ash leaves with a preservation solution, inoculating spore liquid for culturing, and observing the morbidity condition of the leaves after 13 days, the fresh-keeping liquid comprises the following components: 4% of a Chinese prickly ash leaf extract, 1% of citric acid, 0.5% of luteolin, 2.5% of L-proline, 1.5% of methyl jasmonate, 2% of ascorbic acid, 0.5% of acetic acid, 0.35% of chitin, 1% of xanthan gum, 10% of ethanol and 76.65% of sterile water. Aiming at the characteristics of relatively long disease-resistant screening period, relatively large occupied area, relatively large field influence and the like of forest tree varieties, the invention provides the rapid screening method for the rust-resistant Chinese prickly ash and the special fresh-keeping liquid for Chinese prickly ash leaves, and the problem that in-vitro Chinese prickly ash is easy to rot is solved by using the fresh-keeping liquid. The invention provides theoretical basis and technical support for breeding of the rust-resistant pepper variety.
