深海海底边界层原位监测中电源管理系统的设计

摘要

Power management system is the power supply module of the deep seabed boundary layer in ⁃ situ monitoring system. MSP430F149 MCU is adopted as the main control device of the system to control seven programmable DC/DC module. The IAR Embedded Workbench IDE is taken as a software platform to provide real⁃time,stable and effective power management and control. The program is used in the system to control the work status of every DC/DC module to realize the power manage⁃ment and control. The system has followed No.2 Dong⁃fang⁃hong and No.4 Ocean for sea trial. The results confirmed that the management system satisfied the requirements and greatly reduced the power consumption.%　　电源管理系统是深海海底边界层原位检测系统的供电模块。系统以 MSP430F149单片机为主控制器件,控制7块程序可控 DC/DC 模块,IAR Embedded Workbench IDE 为软件平台,提供实时、稳定、有效的电源管理与控制。该系统采用程序控制各个 DC/DC 模块工作与否的方式,达到电源管理与控制的目的。该系统随东方红2号与海洋4号2次出海试验结果表明,这种设计达到了项目的要求,极大地降低了系统的功耗。
