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.
