三分量感应线圈姿态测量系统的设计

Design of Attitude Measurement System for Three-Component Induction Coil

航空电磁系统的接收线圈会受到外界因素的影响而发生姿态的改变,这会使得三分量感应线圈所接收到磁场数据产生偏差.如果得到三分量感应线圈的姿态数据则可以用来做数据校正,但是目前关于姿态方面的研究主要停留在理论阶段,很少见到实际的测量方案.本文设计了一种三分量感应线圈的姿态测量系统,直接在三分量感应线圈上加MEMS姿态传感器模块来测量三分量感应线圈的姿态,并通过GPS模块的授时功能对所采集的数据附上时间戳,最后将数据存人TF卡中为后续的数据校正提供数据支撑.

The receiving coil of the aviation electromagnetic system will be affected by external factors and the attitude will change,which will cause the magnetic field data received by the three-component induction coil to deviate.If the attitude data of the three-component induction coil is obtained,it can be used for data correction,but the current research on attitude mainly stays in the theoretical stage,and the actual measurement scheme is rarely seen.In this paper,a three-component induction coil attitude measurement system is designed.The MEMS attitude sensor is directly applied to the three-component induction coil to measure the attitude of the three-component induction coil and the time of the GPS is used to attach the time to the collected data,finally store the data in the TF card to provide data support for subsequent data correction.
