| Abstract: | A measuring system of magnetic field with full information is designed based on the magnetoresistive mag-netometers of HMC1001 HMC1002 type. It is adapted to the ocean test environment. The design project and imple-mentation are offered. Signals from magnetic sensors′s three components and from the two-axis inclinometer are syn-chronously sampled through the MSP430F5438 controlled multicenter analog to digital device with high resolution. The implementation of the key circuit and the design flow chart of the system software are presented. The data sampled by the system is stored in the mass storage SD card module. Testing results show that the noise of the system is within 5 nT, and the key techniques about low power, high resolution, and mass storage have been solved in this design. The present measuring system can be applied to measurement of underwater magnetic field with full information |
