本文介绍了一种以四旋翼飞行器为载体的时域地空电磁探测系统。该系统采用Cortex-M3内核处理器,以全差分模拟前端压制电磁干扰,实现了24位低噪声、多通道电磁数据同步采样及存储,实现了一套由四旋翼飞行器搭载的时域电磁接收系统,并通过Wi Fi Mesh网络来进行地面远程监控。该系统具有高效、低成本、勘探深度大和空间分辨率高等优点,为地质勘探提供了一种可靠的新方法。
This paper introduces a time-domain electromagnetic ground-based electromagnetic detection system using a quadrotor as a carrier. The system uses a Cortex-M3 core processor to suppress the electromagnetic interference with a fully differential analog front-end, enabling 24-bit synchronous sampling and storage of low-noise and multi-channel electromagnetic data. A time-domain electromagnetic receiving system equipped with a quadrotor , And through the Wi Fi Mesh network for remote monitoring of the ground. The system has the advantages of high efficiency, low cost, large exploration depth and high spatial resolution, which provides a reliable new method for geological exploration.
