This invention relates to the field of intelligent auditing, and more particularly to a graph neural network method and system for mining hidden relationships among multiple sets of enterprise accounts. The method includes: acquiring multiple sets of accounts of a target enterprise, extracting entity and transaction information, and constructing a heterogeneous graph network containing multiple types of nodes such as enterprises, individuals, bank accounts, and transaction vouchers, as well as multiple types of edges such as fund transfers, control, and voucher associations; inputting the heterogeneous graph into a pre-trained GNN, aggregating neighbor features through graph convolutional layers, and updating node embedding vectors; based on the embedding vectors, using an attention mechanism to calculate the confidence of hidden relationships between node pairs, and filtering suspicious related node pairs; performing path reasoning and backtracking on suspicious node pairs, mining multiple paths, and generating a chain of evidence for related paths. This application, by constructing a heterogeneous graph containing multiple types of nodes and edges, comprehensively captures entities such as enterprises, individuals, accounts, and vouchers and their multidimensional relationships, solving the problem that existing methods are unable to comprehensively characterize complex relationship scenarios and capture hidden relationships.

This utility model relates to the field of air handling equipment technology, specifically an airflow regulating device for an air handling equipment. The device includes a purification box with an air inlet slot at the top. A suction fan is rotatably connected to the bottom of the inner wall of the air inlet slot. A connecting block is fixedly connected inside the air inlet slot and above the suction fan. Airflow regulating plates are symmetrically arranged on the outer side of the connecting block. A connecting rod is fixedly connected to the end of each airflow regulating plate away from the connecting block. The end of each connecting rod away from the airflow regulating plate extends to the outer side of the purification box and is fixedly connected to a gear. A gear ring is rotatably connected to the outer side of the purification box, and the gears mesh with the gear ring. Closing slots are provided on both sides of the airflow regulating plates. The beneficial effect of this utility model is that the motor drives one of the gears to rotate, causing the gear ring to link all the gears, enabling precise control of the rotation angle of the airflow regulating plates and achieving precise airflow regulation to meet the precise airflow requirements of different usage scenarios.

This invention provides a method and system for generating products for a circular array solar radio imaging telescope, comprising: generating raw complex visibility function data and raw solar radio spectrum data based on the output signals of each antenna element of the telescope; obtaining calibrated data through multi-dimensional calibration of channels, phase, the entire system, and the spectrum; generating a solar radio brightness temperature image based on the calibrated complex visibility function data, and generating two types of fast-view products by combining the calibrated spectrum data; performing quality inspection on all data products, and classifying and storing qualified products after encapsulation according to standardized naming rules and metadata specifications.
