摘要
为通过MT方法了解大陆岩石圈电性结构,开发了完全自主知识产权的新型大地电磁采集器。介绍了采集器原理,采用ARM平台与LINUX操作系统相结合的硬软件方案,引入GPS授时与恒温晶振实现多点同步技术、低噪声技术、大容量存储技术、低功耗技术以及嵌入式Linux软件技术。通过与国外同类仪器的野外对比试验表明,仪器指标满足标准MT测量要求。
Through the MT approach to understanding the electrical structure of continental lithosphere,this paper developed a new type of intellectual property rights magnetotelluric recorder.The paper introduced the principle of hardware,based on ARM platform and LINUX operating system,GPS timing and OCXO multi-point synchronization technology,low-noise technology,high-capacity storage technology,low-power technology,and embedded Linux technology.Instruments with similar foreign field comparison tests show that the iustrument weets the equipment standards for MT measurement requirements.
