Steam pipeline leakage identification method and device, storage medium and terminal equipment

Abstract

The invention discloses a steam pipeline leakage identification method and device, a storage medium and terminal equipment, and the method comprises the steps: obtaining a topological network structure of a pipeline, and determining a rule according to a preset numerical value, and obtaining a central value and a weight value of the topological network structure as initial antibodies; performing iterative computation on all the initial antibodies according to parameters of a preset immune genetic algorithm, so as to update a current fitness function through an error obtained by an RBF neural network algorithm in each iterative computation, and then performing evolutionary operation on all the initial antibodies according to the updated fitness function, so as to obtain an evolutionary result of all the initial antibodies; updating the immune memory cells according to all initial antibodies after evolution operation until the number of iterations reaches a preset value to obtain a plurality of iterative antibodies; and outputting a pipeline leakage prediction result according to the plurality of iterative antibodies. Compared with the prior art, the method can improve the accuracy and recognition efficiency of pipeline steam detection.

Description

technical field [0001] The invention belongs to the field of steam pipeline leakage detection, and in particular relates to a steam pipeline leakage identification method, device, storage medium and terminal equipment. Background technique [0002] In power plants, steam pipes are an indispensable and important part. The working environment of these pipes is very harsh, and they are prone to corrosion, cracks, and fatigue damage under the action of steam, which will eventually lead to steam leakage accidents in the pipes, which are harmful to power plant employees and equipment. Safety is very harmful, especially when the gas pipeline contains flammable, explosive or toxic gases, how to detect accidents in a timely and accurate manner is the main problem faced by such pipeline leakage monitoring. [0003] At this stage, due to the diversity and complexity of steam pipeline leakage, there is no general pipeline leakage detection method at home and abroad, and different detect...
