摘　　要：为进一步降低矢量水听器信号采集处理系统对水下滑翔机平台的续航影响,设计了一种以ARM和DSP为核心控制器的低功耗信号采集处理系统。利用ARM控制器实现系统的多种工作模式,以达到不同状态下的最佳功耗控制。此外,在控制软件中加入必要的优先级设计和流水线设计,以提高系统硬件控制效率,最后利用功率测试仪对系统不同工作模式进行测试。结果表明,低功耗模式下平均功耗约为1.27 W,实时处理模式下平均功耗约为4.29 W。在长时间连续工作情况下,可大幅度降低实时处理模式的工作时间占比,功耗控制效果显著,有效证明了该方案的有效性和优越性。To further reduce the impact of vector hydrophone signal acquisition and processing systems on the endurance of underwater glider platforms,a low-power signal acquisition and processing system with ARM and DSP as core controllers was designed.Achieve multiple operating modes of the system by utilizing ARM controllers,in order to achieve optimal power consumption control in different states.In addition,necessary priority design and pipeline design are added to the control software to improve the hardware control efficiency of the system.Finally,different working modes of the system are tested using a power tester.The results show that the average power consumption in low-power mode is about 1.27 W,and the average power consumption in real-time processing mode is about 4.29 W.In the case of long-time continuous operating,the proportion of real-time processing mode operating time can be significantly reduced,and the power control effect is significant,which effectively proves the effectiveness and superiority of this scheme.
