This utility model relates to the field of power system monitoring technology, specifically to a wireless monitoring sensor for the corrosion status of substation grounding grids. It includes a cylindrical base, a heat dissipation chassis fixedly mounted on the upper end of the cylindrical base, a layered shielding chamber fixedly mounted on the upper end of the heat dissipation chassis, and a shell fixedly mounted on the upper end of the heat dissipation chassis. The shell is configured as an umbrella cone structure, and a pointed cone-shaped energy-concentrating head is fixedly mounted on the upper end of the shell. The pointed cone-shaped energy-concentrating head is made of conductive and corrosion-resistant materials. Utilizing the principle of point discharge, this utility model enhances the ability to converge spatial electromagnetic field signals, thereby improving signal acquisition sensitivity and ensuring the accuracy of monitoring data. Simultaneously, by configuring the shell as an umbrella cone structure and providing an internal insulating cavity filled with heat-insulating material, the device's environmental adaptability is improved.

The invention provides a graph data representation method based on multiple virtual nodes and random hash propagation, and relates to the field of graph data representation, and the method comprises the steps: carrying out node importance evaluation and feature similarity clustering on an original graph, and dividing the nodes into a plurality of node clusters; introducing at least one virtual node for each node cluster, constructing a connection relationship between the virtual node and all real nodes in the cluster, and forming a structure enhancement graph; maintaining a sketch vector of which the fixed dimension is K for each real node and each virtual node on the structure enhancement graph; based on a random hash function family, performing multi-round propagation and updating on the sketch vector, and generating node representation fusing node attributes and multi-order structure information; and directly applying the node representation to a graph data processing task. According to the technical scheme, joint modeling of the node attribute information and the multi-order structure information in the complex graph structure is achieved.
