摘　　要：针对深海海底边界层原位监测的特点,设计了适用于深海海底的原位化学要素数据采集系统。该系统由数据采集器以及pH传感器、溶解氧传感器、二氧化碳传感器和甲烷传感器等化学要素监测仪器组成。整个数据采集系统以ARM9为硬件平台,具有多路模拟量采集、数字量采集、大容量存储、常用通信端口和基本数据处理与分析功能,对于深海海底边界层原位监测具有现实的应用意义。通过实验室模拟深海环境试验和稳定性试验以及实海况海试的验证,证明了设计的可行性。Aiming at the characteristics of bathybic boundary in-situ monitor, a in-situ chemical element data acquisition system was proposed, which could be used on deep-sea environment. The system consists of data acquisition unit, pH sensor, DO sensor, CO2 sensor and CH4 sensor. The data acquisition system based on ARM9 could collect multiplex analog and digital signals and has the ability of large capability memory, current communication modes, basic data process and analysis, which has the practical application signification for bathybic boundary monitor. High pressure test, stability test in lab and sea trial results demonstrate that the proposed chemical element monitoring system could work properly in deep sea.
