河口底边界层座底支架稳定性实时监测技术

A Real-time Monitoring Technique for Tripod Stability in Estuarine Bottom Boundary Layers

河口水文座底式观测中,如何确保支架的稳定性是一个关键问题。现有的方法是通过回收数据推测测量过程中支架的状况,缺乏观测期间支架状态的实时监测。利用声学原理设计了一套简单的实时通讯姿态监测仪,实验结果表明,监测仪可将座底支架的姿态信息从河床底部实时传送到测量船,提供支架姿态实时的时间序列信息,为获取高质量的观测数据提供了可靠的技术保障。

How to ensure the stability of the tripod is a critical issue in bottom boundary layer observations in coastal area. However, the existing methods lack the ability of real-time monitoring of the tripod state. A posture monitor was designed based on acoustic mechanism with real-time communications. The experimental results showed that the monitoring can effectively transfer the state signal from the bed to the vessel and can obtain time series of the tripod state during the whole survey. This simple and reliable technique provides the strong guarantee for the BBL observations in the shallow waters.
