摘　　要：针对热液区环境参数数据采集的要求,研制了一套拖拽式热液探测系统。该系统使用MSP430F169作为核心微控制芯片,采用了外接16位高精度A/D转换模块,并配置了通过巡检工作方式进行采集的多路采集电路。该系统具有电路结构简单、测量精度高和功耗低的特点,满足了深海条件下的长期、连续、离线和高精度的数据采集要求。经过一系列实验室实验,实验结果表明:热液探测系统各通道的测量精度和线性度均满足要求;通过利用龟山岛海域热液区海试结果,在水下16.7 m水深处(坐标24.834 19N;121.961 98E)发现了一处活动的热液泉口,进一步验证了该套热液探测系统的可靠性。Aiming at the special requirements of hydrothermal liquid area environmental parameter acquisition, a drag hydrothermal detection system was designed. MSP430F169 was used as the core micro control unit（MCU）. An external 16 bits A/D converter and two multiplexers were used in the data logger,which highly simplified the electronic circuit design. According to laboratory experiments, the results indicate that the data logger can meet the accuracy and linearity requirements. Through Kueishantao Islet hydrothermal liquid area sea trials, a hydrothermal vent （24.834 19N, 121.961 98E） is found 16.7 meters beneath the sea. The reliability of the hydrothermal detection system is further verified.
