摘要
水下声信号是水下探测系统实现对水中目标远程探测识别的主要信息之一,有效获取水下声信号是一个十分重要的问题。探测系统数据采集部分的速度、精度及功耗直接影响整个系统的性能。针对水下探测系统对数据采集部分的要求,利用微功耗器件THS1206与TMS320VC5509A设计的水下数据采集系统速度快、功耗低、精度高,可同时采集多路水下信号,满足探测识别系统对于数据采集部分的要求。对整个数据采集系统,给出了系统软硬件设计的关键接口原理框图和流程图。整个采集系统经过实际测试,达到了设计要求。
The underwater acoustic signal is the main information for the underwater detection and identification system, so it is very important to get the acoustic signal efficiently. However, the data acquisition system must match many factors such as acquisition speed, accuracy, power. To satisfy these requirements, ultra-power devices THS1206 and TMS320VC5509A are used to design the underwater acoustic data acquisition system. The key points of the whole system are described. It is demonstrated that the whole system matches the factors which the data acquisition system expects.
