应用于海洋时间序列沉积物捕获器控制系统方法研究

Study of marine time series sediment trap control system

提出了一种海洋沉积物捕获器控制系统的软/硬件设计方案。该方案采用低功耗的硬件结构,多种冗余技术的软件设计,满足了沉积物捕获器在海底可长达1 a的低功耗、自动定时采集沉积物样品的要求。经过实验,该控制系统运行可靠,采样瓶切换控制准确,运行数据记录完整,具有广阔的应用前景。

This paper presents a new design scheme for hardware and software of marine sediment trap . The scheme includes usage of a new structure with low power consumption in hardware and multiple redundant in software. It can run up to one year in the ocean with low power consumption and automatically obtain sediment sample. The experimental results show that the system runs reliably, moves steadily, records completely, therefore it is promising in trapping marine sediment.
