基于MSP430的深海低功耗数据采集系统

针对深水作业条件下对数据采集设备的特殊要求，提出了具有低功耗、高精度、耐高压特点的水下多通道数据采集器的设计方法。该系统采用MSP430F169作为核心微控制芯片，并通过精心的外围电路设计，实现了系统低功耗和高精度运行；同时通过对电路板机械封装，满足了水深3000m高压环境下对系统的耐压防漏要求。高压仓试验结果表明，该数据采集系统采集到的数据稳定性能良好、精度高，机械封装设计能够满足深海密封防漏要求。

Low power-consumption deep-sea data logger based on MSP430

To meeting the special requirement for data acquirement instrument(data logger) in deep-sea water,a design of data logger system was proposed,which was featured by low power consumption,high accuracy and high compression resistance.By using MSP430F169 as its micro-controller unit(MCU) and employing low-power chips in peripheral circuits,the demand for low-power consumption and high accuracy was fullfilled.A design of mechanism encapsulation for protecting data logger in 3 000 m was also proposed.A high-pres...
