| 将小型多旋翼无人机应用于海上磁力探测是一种全新的海洋磁力测量手段，本文针对小型多旋翼无人机海洋航磁测量系统的实现需要，设计了一套便携、高精度的航磁数据采集系统。该系统以STM32F407ZGT6为控制核心，结合FPGA和等精度测频原理，实现了旋翼无人机在航磁任务中的磁力数据、定位数据及姿态数据的实时采集和存储，并在航磁任务开始前通过WiFi无线通信实现机载系统自检功能，确保仪器处于正常工作状态。航磁任务中每3分钟进行一次数据保存，航磁任务结束后通过按键再次保存数据，以保证数据的完整性。文中介绍了数据采集系统的硬件组成和软件编写思路，并通过实际航磁作业测试，验证了该采集系统的有效性。 |

| The application of small multi-rotor UAVs to marine aeromagnetic survey is a brand-new magnetic measurement method.Aiming at the realization needs of a small multi-rotor UAV marine aeromagnetic measurement system, this paper designs a portable and high precision aeromagnetic data acquisition system.The system uses STM32F407ZGT6 as the control core, combined with FPGA and the principle of equal-precision frequency measurement to realize the real-time acquisition and storage of magnetic data, positioning data and attitude data of the rotor drone in aeromagnetic missions, and before the start of the aeromagnetic mission Realize the self-check function of the airborne system through WiFi wireless communication to ensure that the instrument is in normal working condition.During the aeromagnetic missdion, data is saved every 3 minutes. After the aeromagnetic mission is over, press the button to save the data again to ensure the integrity of the data. The paper introduces the hardware composition and software compilation ideas of the data acquisition system, and verifies the feasibility of the acquisition system through actual aeromagnetic operations tests. |
