Abstract
The article deals with the inverse problem of determining the transient resistance of the main pipeline insulating coating. For this, UAV measurements of the magnetic induction vector modulus of the magnetic field excited by the system of electrochemical cathodic protection of pipelines are used. The solution method is based on Tikhonov's method for finding the extremal of the regularizing functional. The developed algorithm is implemented in software. The results of computational experiments are presented.
Highlights
In terms of cargo transportation pipeline transport takes a leading position in the world
The article concerns the mathematical model of the mathematical geophysics problem to determine transition resistance at the boundary “ground/pipe” of the main pipeline on the basis of magnetometry data
Inverse problem solution is found as an extremal of a regularizing functional by A.N
Summary
In terms of cargo transportation pipeline transport takes a leading position in the world. Injected by cathodic protection stations (CPS), when passing anode beds an electrical field with pipeline ground, its insulating coating, running down along the pipe metal towards the drainage points carries information on physical and geometrical properties of the system “anode/ground/pipe”.
