摘要

摘要: 为解决试验中水声信息无法被高保真、长时间采集存储等问题, 设计了一种基于ARM微控制器和大容量通用储存卡的微型水声信号采集与存储系统, 设计中将高集成度模拟、数字芯片技术有机结合, 该采集系统硬件具有体积小巧(3×8 cm)、低功耗、参数设置灵活等优点, 方便嵌入各型小空间水声设备内部; 软件设计采用“直接存储器访问(DMA)+乒乓缓冲区”的采集模式, 确保微控制器轻载实现信号无间断、无丢点采集存储, 保证系统连续长时间工作稳定可靠。水下环境噪声测量试验验证了该系统的合理性和工作可靠性。

Abstract: Based on the advanced RISC machines(ARM) microcontroller and TF card, a micro underwater acoustic signal acquisition and storage system was designed to solve the problem that the underwater acoustic information in test cannot be collected and stored with high fidelity for a long time. High integration analog and digital chips were combined effectively in the hardware design to gain the advantages of small size(3×8 cm), low power consumption, flexible parameter setting, and convenient embedding into small-size acoustic equipment. The software was designed by using direct memory access(DMA) plus ping-pang buffer acquisition mode to ensure data acquisition and storage of the micro controller without interruption and missing, and hence to support the system working stably and reliably for a long time. This system has been successfully applied in an underwater noise acquisition experiment.
