摘要
介绍了一种基于Atmel AT91SAM9G20(ARM926EJ-S核)低功耗微处理器和Actel AGL600(低功耗Flash-based FPGA)并融合嵌入式Linux技术的便携式人工地震数据采集系统的设计原理和实现方法。该设计引入动态电源管理技术,根据系统负载自动进行微处理器工作频率调节和外围I/O设备的工作模式调整。本数据采集系统功耗低、体积小,野外使用安装便捷,对降低数据采集成本、延长系统有效工作时间、提高野外工作效率有着积极意义。
This article describes the design principles and implementation methods of an artificial seismic sounding data acquisition system,which is based on ARM926EJ-S core processor （Atmel AT91SAM9G20） and ultra low-power FPGA chip（Actel AGL600） in combination with embedded Linux technology. By making use of existing seismic instruments and embedded technology, design a sounding seismic seismograph equipment that features low power,small size,easy to carry and internet access. Besides, dynamic CPU frequency scaling is introduced in this design to further reduce watt loss.
