Data transmission method and device based on grading

The invention discloses a grading-based data transmission method and device. The method comprises the following steps: acquiring a plurality of computing nodes and monitoring data acquired by each computing node; inputting the monitoring data into a target attribute graph obtained by pre-training to obtain data features of the monitoring data; grading the monitoring data based on the data features to obtain more than two data sets; each data set corresponds to a different importance level; constructing a communication network diagram based on the connection relationship among the plurality of computing nodes; each computing node is a network diagram node of the communication network diagram, and the connection relationship among the plurality of computing nodes is an edge of the communication network diagram; and transmitting the monitoring data among the network diagram nodes based on the communication network diagram and the importance level. According to the invention, the data transmission efficiency and
