4 results about "Data coherence" patented technology

The invention relates to the technical field of data processing, in particular to a river pollution monitoring management method fused with environmental information perception. According to the method, monitoring points are classified according to information collected in a non-rainfall period, and a plurality of monitoring point clusters are obtained. In the target rainfall period, the rainfall influence degree of the monitoring points is determined by analyzing pollutant concentration data changes before and after analysis and rainfall information, and then the target monitoring points needing data correction are screened out. A time correction method is adopted, reference time periods are selected in the non-rainfall time periods, the reference weight of each reference time period is determined by analyzing the time sequence position of the reference time periods and the rainfall influence degree of the latest rainfall time period, and then time correction is conducted; and further performing space correction by using other monitoring points in the monitoring point cluster obtained by classification to finally obtain corrected pollutant concentration data. According to the method, the influence of rainfall on pollutant concentration data is eliminated, and the data reference is increased while the data coherence is ensured.

The invention discloses a verification method for a conversion field type between data sources and a related device, and belongs to the technical field of data conversion verification. The method comprises the following steps: acquiring field source information and field converted information of data to be verified; based on a pre-trained field type mapping verification model, in combination with the field source information of the to-be-verified data and the information after field conversion, analyzing a field semantic feature set of the to-be-verified data, including a field type semantic data set and a field content semantic data set; and based on the field semantic feature set of the to-be-verified data, a field type conversion verification feature value and a field content coherence feature value of the to-be-verified data are analyzed, and the to-be-verified data are subjected to joint verification processing based on the field type conversion verification feature value and the field content coherence feature value. Therefore, double-layer collaborative verification of semantic consistency and content stability is realized, and comprehensive guarantee of a field conversion result in the aspects of semantic interpretation and data coherence is further realized.

This invention discloses a UVM verification method and system for processor core bus protocol to AXI protocol conversion. The method includes: extending the general interface UVC to obtain a directional interface UVC adapted to both the processor core bus protocol and the AXI protocol; inputting an excitation sequence to the design under test (DUT) through the directional interface UVC, acquiring the signals output by the DUT and converting them into data frames; processing the original bus protocol request, outputting a reference data frame, and comparing the acquired data frame with the reference data frame; performing data coherence detection on the DUT using a storage model; and determining whether the verification passes by combining the comparison result and the data coherence detection result. This invention effectively solves the technical problems of the lack of a dedicated verification method for the processor core bus protocol to AXI protocol conversion module, the difficulty of data coherence verification, and the long verification convergence period.
