单点声学多普勒流速仪中电源管理系统的设计

Design of power management system in single point acoustic Doppler velocimeter

电源管理系统是单点声学多普勒流速仪(ADV)的供电管理系统。该系统以MSP430F5438A单片机为主控制器件,负责ADV系统内部的低功耗控制及RTC功能,是ADV系统内部及其与外部相互通信必须经过的中转处理站,是ADV系统的重要组成部分。该系统已经进行了湖试,试验结果表明,这种设计达到了项目的要求,大大地降低了整个系统的功耗。

The power management system is the power supply management system of the single point acoustic Doppler velo- cimeter （ADV）. The MSP430F5438A is taken as the main control device of the system to control the low-power consumption in- side the ADV system and realize the RTC function, which is the transit processing station for the interior communication and ex- ternal communication of the ADV system, and the important component of the ADV system. The system was tested in the lake. The test results show that the design has reached the project requirement, and reduced the power consumption of the whole sys- tem greatly.
