Abstract
- Magnetic field measurement is one of the key contents in the field of electromagnetic protection. In this paper, a magnetic field measurement system based on distributed magnetic sensing and a high-accuracy numerical integration method is proposed. And a magnetic field sensor with simple structure, small size, and wide measurement band is designed, which includes three magnetic field measurement coils that can realize the accurate measurement of a three-dimensional magnetic field. The output of the magnetic field measurement coil is a differential signal that needs to be reduced by the integrator. To solve the problems of traditional analog integrator and common digital integrator, this paper proposes a high-precision digital integral algorithm based on Gauss algorithm, which can effectively improve the accuracy of the integrator. Test results indicate that the error of the magnetic field measurement system is less than 5%in the range of 0.05-5T. [ABSTRACT FROM AUTHOR]
