摘要
电池供电的自容式叶绿素仪需要在水下长期工作,系统平均功耗必须低,其主要功耗来自于采集控制电路,为满足自容式叶绿素仪的采集控制电路的功耗和处理能力要求,提出基于MSP430F1611的低功耗系统软硬件方案,并针对功耗和处理能力的矛盾,研究了MSP430F1611的主频与功耗之间的关系,通过实测和理论计算,提供了在特定任务条件下的采集控制电路的功耗优化方法。
A battery-powered self-contained chlorophyll device has to work underwater for a long time, thus the power consumption of the system must be low. The power consumption of the system mainly comes from the acquisition and control circuit. To meet the power and processing performance demands of the acquisition and control circuit in a self-contained chlorophyll device, a low-power system scheme on software and hardware based on MSP430F1611 is provided. Focusing on the contradiction between power consumption and processing performance, studies are done on the relation between the frequency of MSP430F1611 and power. Through measurement and theoretical calculation, a method to optimize the power dissipation of the acquisition and control circuit in a particular task is provided.
