Other AbstractThis paper presents a data acquisition system of magnetometer with field programmable gate array (FPGA). The system takes the AD7732 as the ADC, and sample 3 sensor signals by using FPGA as the sampling controller, then the sampled values are transmitted in asynchronous serial mode to the upper computer through RS485 interface. Through the deep analysis of the writing and reading time diagrams of ad7732, VerilogHDL language is adapted to compile the data acquisition program. Utilizing the parallel processing capabilities of FPGA, 3 channel signals can be sampled in parallel, which realize the real time acquisition and transmission of magnetic signal. Therefore, it satisfies the requirements of high resolution and high reliability for the magnetometer design.
