| 摘 要： | 国外的水合物探测试验证明，可控源电磁法是探测天然气水合物的有效方法之一.开展海底可控源电磁法工作的重点之一在于研制高精度、高可靠、低功耗观测海底可控源电磁信号的设备.为可靠地观测海底可控源电磁场宽频带、大动态范围信号，设计了以Linux与ARM9相结合的测量电路，并开发了Linux2.4内核下的设备驱动程序.本文分别论述了采集硬件原理，Linux字符设备驱动模型，SSC和GPS对钟驱动实例.

| Abstract: | Marine CSEM is an effective method for Methane Hydrate detection, which is validated by foreign Methane Hydrate exploration tests. The key work of marine CSEM is developing equipment which acquires CSEM signal and must be of high precision, high robustness, and low power .To acquire ultra wide band and high dynamic range CSEM signal intelligently, we have designed measurement circuit based on Linux and ARM9, developed the Linux drivers for data acquisition under Linux 2.4 kernel. This paper describes the elements of acquire hardware and char devices driver, example of drivers for SSC and locking GPS. |
