And then the terminal fits the resistivity corresponding to each structural feature data and the resistance model radius corresponding to each structural feature data based on each structural feature data through a resistance fitting strategy, and determines the structural resistance data of each structural feature data through the resistivity corresponding to each structural feature data and the resistance model radius corresponding to each structural feature data. And then, the terminal establishes a cable joint simulation model by a traditional cable joint simulation model establishing mode based on the obtained structural feature data.
Step S102, carrying out simulation current transmission processing on the cable joint simulation model to obtain temperature field distribution information of the cable joint, and identifying temperature data corresponding to each structural feature data based on the temperature field distribution information to obtain a first temperature distribution curve of the cable joint simulation model.
In this embodiment, the terminal performs simulation current transmission processing on the cable joint simulation model based on the cable joint simulation model through a simulation voltage and a simulation current preset in the terminal, and obtains temperature field distribution information corresponding to each structural feature data of the cable joint in a simulation operation process. The temperature field distribution information is distribution information of temperature data corresponding to all structural feature data of the cable joint structure simulation model.
