ARM的水声浮标嵌入式应用

ARM’s acoustic buoy embedded application

传统的水声浮标采集到的四通道信号有幅值相位偏差。因此对ARM的水声浮标嵌入式应用进行设计。对浮标标体的运动进行计算,得到适合的标体重量以及重心高度,对标体结构进行设计,在此基础上更换了控制单元的单片机和水听器阵的原材料,优化了信号修正电路,在ARM水声浮标程序设计中,改变了数据采集、传输以及储存方式,完成了ARM的水声浮标嵌入式应用设计。为了验证其工作可靠性,设计了通道信号一致性的测试,结果表明设计的ARM水声浮标四通道收集到的信号叠加在一起之后无明显差异,具有较好的信号一致性。验证了设计的ARM水声浮标嵌入式的有效性。

The four channel signals collected by traditional acoustic buoys have amplitude and phase deviation.Therefore,the embedded application of ARM acoustic buoy is designed.Motion of the buoy body calculation,get the suitable standard weight and center of gravity height,for the structure design,on the basis of the replacement control unit of the single chip microcomputer and hydrophone array of raw materials,optimization of the signal correction circuit,in the ARM acoustic buoy programming,changed the way data acquisition,transmission and storage,completed the ARM of the acoustic buoy embedded application design.In order to verify its working reliability,the channel signal consistency test is designed.The results show that there is no obvious difference between the signals collected from the four channels of ARM acoustic buoy,which has good signal consistency.The effectiveness of embedded ARM acoustic buoy is verified.
