Abstract
The present invention relates to the technical field of maglev transportation, specifically revealing a method and apparatus for measuring magnetic field intensity in high-temperature superconducting maglev transportation systems. The method includes: Establishing the top surface of the permanent magnet guideway (PMG) as the reference datum for magnetic field intensity measurements; developing a multi-point chord measurement system with parameters including system sampling interval, system order, and chord measurement configuration; computing intermediate chord values; constructing an inversion model incorporating the least squares method and employing this model to derive the vertical displacement of the reference chord baseline; determining gap sensor locations and deploying an array of Hall effect sensors along the direction of magnetic field intensity measurement; adjusting the reference datum position; and calculating the magnetic field intensity distribution above the reference datum using interpolation techniques based on the Hall effect sensor array measurements.
