摘要
电子罗盘由三轴磁阻传感器、两个倾角传感器和MCU构成。在实际中,复杂环境的磁场干扰和不可避免的倾斜会影响电子罗盘,为了提高测量精度,必须对其进行环境干扰补偿和倾角补偿。本文详细阐述了倾角补偿和干扰补偿的原理,设计了简单的电子罗盘测试样机进行验证,并由实验数据,分析总结出了测量误差图表和结论。
The electronic compass is constituted by The three-axis magnetoresistive sensors,two tilt sensor and MCU.In practice,the complex environment of magnetic interference and the inevitable tilt will affect the electronic compass,in order to improve the measurement accuracy,it must conduct an environmental disturbance compensation and tilt compensation.This paper describes the principle of tilt compensation and interference compensation.Design a simple electronic compass test prototype to verify.By the experimental data,analysis,summed up the charts and conclusions of the measurement error.
