| 摘 要： | 针对移动式海洋地震仪对控制系统电路设计的可靠性和低功耗的需求,提出了一种基于Cortex-M4内核芯片的硬件电路设计方案。首先选用超低功耗的STM32L4芯片作为微控制单元,在保证高运行能力的同时降低自身功耗;其次针对MCU(Microprogrammed Control Unit)、传感器等超低功耗模块提出针对性的两级降压方案,从而大大提高电路的电能转换效率;对于浮力调节模块、通信模块等高功耗模块,选用合适的降压芯片保证电路安全和提高转换效率;最后针对外部设备的周围电路进行滤波和保护处理。通过试验分别验证了不同模块的可靠性,证明该硬件电路可以支撑地震仪完成完整的观测任务,电路设计可靠性高。

| 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. |
