The application discloses a CAD model through-hole feature recognition and processing method based on a graph neural network, comprising the following steps: constructing a surface adjacency graph according to the B-Rep representation of a CAD model; extracting differential geometric information and attribute information of each surface to construct a node initial feature vector; classifying each surface by using a graph neural network to determine a through-hole surface recognition result; performing triangular subdivision on the CAD model, deleting all grids located on the through-hole surface, applying a hole filling algorithm to repair the grid gap, determining a final grid model with the through-hole feature removed, or associating the surface label with a grid generation algorithm to guide grid generation and determine the finally generated anisotropic grid. The application comprehensively improves the recognition accuracy, processing efficiency and output quality while maintaining the lightweight of the model, and provides reliable technical support for the CAD / CAE integrated process.

The application relates to a power grid application layer instruction level detection method fusing control service logic. For power grid application layer instruction level detection, a rule matching-based method is used to detect abnormal messages and attack messages; abnormal message rules are designed according to protocol specifications, and a mature snort network attack rule library is used as an attack message feature library; for the discrete characteristics of service feature values, an abnormal detection technology based on clustering learning is proposed to realize abnormal identification of service instruction frequencies and service feature codes.
