摘要：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3 000 m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。

Abstract: To meeting the special requirement for data acquirement instrument (data logger) in deepsea 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 microcontroller unit(MCU) and employing lowpower chips in peripheral circuits, the demand for lowpower consumption and high accuracy was fullfilled. A design of mechanism encapsulation for protecting data logger in 3 000 m was also proposed. A highpressure storehouse was used to simulate the deepsea high pressure for experimental investigations. The experimantal results show that the data acquired by the data logger system is accurate and steady, the leak proof requirement of system in scientific research in deepsea can be met by the mechanism encapsulation.
Key words: data logger; low powerconsumption; MSP430; deepsea; mechanism encapsulation
