摘要: 本文通过分析巨磁阻效应，采用自主研制的多层膜结构的GMR磁传感器研制二维电子罗盘，该电子罗盘包括二只GMR磁传感器和信号处理电路。通过对传感器进行静态特性标定，给出了电子罗盘的整体设计方案。采用了AD620仪表放大器、arduino uno微处理器和12864LCD液晶显示屏分别实现了差分放大、信号处理以及液晶显示，并在IDE编程软件中采用C语言对电子罗盘信号处理模块进行软件编程，在二维磁场中实现了当前方位测量的功能。通过对研制的电子罗盘特性进行测试与分析，实验结果表明，本文设计的巨磁阻电子罗盘实现了基本的功能。
Abstract: By analyzing the giant magneto-resistance effect, a two-dimensional electronic compass was de-veloped, which is based on a self-developed multilayer film structure GMR magnetic sensor. The electronic compass includes two GMR magnetic sensors and a signal circuit. Through the calibration of the static characteristics of the sensor, the overall design of the electronic compass was given. The AD620 instrumentation amplifier, arduino uno microprocessor and 12864LCD liquid crystal display were used to implement differential amplification, signal processing and liquid crystal display. And in the IDE programming software, C language is used to program the electronic compass master control system to achieve the function of determining the current position in the two-dimensional magnetic field. Through testing and analyzing the characteristics of the developed electronic compass, the experimental results show that the GMR electronic compass developed by this program achieves the basic functions.
