Abstract

Aiming at the requirements of the mobile ocean seismograph for high reliability and low power consumption of the control system, a hardware circuit design scheme based on the Cortex-M4 core was proposed. Firstly, the ultra-low-power consumption STM32L4 was selected as the MCU(Microprogrammed Control Unit) to ensure high operating capacity and reduce power consumption; secondly, a targeted two-level voltage reduction scheme was proposed for the ultra-low-power modules, such as MCU and sensor system, to greatly improve the power conversion efficiency of the circuit and a suitable buck chips was selected for the high-power modules such as buoyancy adjustment systems and communication systems to ensure circuit safety and improve the conversion efficiency. Finally, the peripheral circuit was filtered and protected. The reliability of the different modules was verified through tests which prove that the hardware circuit can support the seismograph to achieve the complete observation task and the circuit design is highly reliable.
