摘要
以DSP芯片TMS320F2812作为控制核心,MEMS水听器作为接收端,设计了水下测距系统,该系统具有体积小、成本低等优点,主要包括DSP硬件、发射模块和接收模块等。在水库环境对系统进行了测试,测试结果表明测量距离和实际距离比较接近。分析导致误差存在的原因,验证了系统方案的可行性。
An undersea ranging system was designed,which uses DSP chip TMS320 F2812 as the control core and MEMS hydrophone as the receiver .The system has such advantages as small size and low cost .It is mainly consisted of DSP hardware,emitting module and receiving module .The ranging system was tested in a reservoir,and the results showed that the measured distance was approximate to the actual distance .The causes of the error were analyzed,which verified the feasibility of the scheme .
