The present invention belongs to the technical field of data security of industrial Internet, and provides a method and system for detecting abnormal nodes in industrial Internet, a medium and a device. In the industrial Internet, different data holders firstly transform their own local node data into graphic data. Before local model training, the data holders firstly use a spectral clustering algorithm to perform certain clustering operations on local data, cluster the node data of the same category into the same cluster, and then perform local model training on a clustered result to obtain partial aggregation features. The trained partial features are uploaded to a trusted third-party server for global feature aggregation. Through an attention mechanism, different weights are assigned for partial features uploaded by different data holders, and the aggregated global features are delivered to each data holder for a new round of training.

Method and system for detecting abnormal nodes in industrial internet, and medium and device

In a fracturing control apparatus, a first chemical agent storage tank is connected with a first delivery pump, and a material outlet of the first delivery pump communicates with a first position of a first fracturing fluid conveying pipeline. An outlet of the first fracturing fluid conveying pipeline communicates with an inlet of a fracturing pump, an outlet of the fracturing pump communicates with an inlet of a second fracturing fluid conveying pipeline, and a first flow detector is arranged at a second position of the second fracturing fluid conveying pipeline. The first delivery pump is connected with a first output interface of a controller, and the first flow detector is connected with a first input interface of the controller. The fracturing control apparatus and the control method of the fracturing control apparatus are used for adding chemical agents into fracturing fluids.

Fracturing control apparatus and control method therefor

Preparation method for a polyurethane optical resin and applications thereof. The preparation method for the polyurethane optical resin comprises: a raw material composition comprising isocyanate and a polythiol compound undergoes a polymerization to produce the polyurethane optical resin. The turbidity value of the isocyanate used in the raw material composition is controlled at ≤2 NTU. The polyurethane optical resin produced is applicable in manufacturing optical products.

Preparation method for polyurethane optical resin and applications thereof
