The invention discloses a temperature prediction method and device and a storage medium, and belongs to the technical field of pipeline transportation. The method comprises: obtaining N groups of actual measurement parameters of a target pipeline to be subjected to temperature prediction, and normalizing the N groups of actual measurement parameters to obtain N groups of normalized actual measurement parameters, taking the N groups of normalized actual measurement parameters as input of a temperature prediction model, determining M prediction temperatures through the temperature prediction model, and taking the M prediction temperatures as M prediction temperatures of downstream fluid of the target pipeline in a second time period. According to the method, N groups of normalized actual measurement parameters are determined based on N groups of actual measurement parameters of the target pipeline obtained in the first time period, and then M predicted temperatures of downstream fluid ofthe target pipeline in the second time period are predicted through a temperature prediction model. Since the M predicted temperatures are obtained through the temperature prediction model on the basis of the N groups of actual measurement parameters, the accuracy of the M predicted temperatures is ensured.
Description
technical field [0001] The present application relates to the technical field of pipeline transportation, in particular to a temperature prediction method, device and storage medium. Background technique [0002] When the fluid is transported through the pipeline, in order to ensure the normal transport of the fluid in different environments, a heating furnace is installed to heat the transported fluid. However, if the temperature of the heated fluid is too high, it is easy to cause waste of heat, or the temperature of the heated fluid is low, such as the transported fluid is oil, it is easy to precipitate wax crystals and coalesce on the inner wall of the pipeline. Reduce the flow area, reduce the efficiency of pipeline transportation, and even cause pipeline blockage, causing safety accidents. Therefore, in order to avoid the waste of heat, the reduction of pipeline transportation efficiency or the occurrence of safety accidents, in the process of fluid transportation, de...
