置于大型浮标内的水质参数长期测量系统的设计及应用

A long-term water quality monitoring system embedded in a large buoy

为有效解决海洋生物的附着污染问题,延长各种海洋仪器的使用寿命,设计了一种新型的海洋环境连续监测系统。该系统放置在大型海洋资料浮标内,采用海水抽样测量方法,将海水抽取到浮标舱内的容器中测量,而后使用消毒液和清水对容器和传感器进行消毒和清洗。系统通过定点连续监测将数据传输到岸站,与目前浮标常用仪器比测得出,所采集数据稳定可靠。该系统能够将水质传感器的寿命至少延长一年,并提高其长时间测量的准确度和可靠性。

This paper presents a new ocean environment continuous monitoring system to solve marine biofouling problem and to increase the lifetime of oceanographic instrumentations. The system is embedded in a large ocean data buoy and pumps seawater into a container to measure data with seawater sampling method. The system then washes the container and sensors with disinfectant and fresh water. The monitoring data is transmitted to a onshore control center and compared with that of the common instrumentations. Experiments show that the system can extend the lifetime of a water quality sensor to at least one year and improve its long-term accuracy and reliability.
