海床基海洋环境自动监测系统的研究

Research on the Seabed Based Automatic Environmental Monitoring System

介绍了一种适用于在浅海(水深100 m以内)工作的海床基海洋环境自动监测系统的工作原理和组成。对水下集成监测平台、数据采集和传输、系统布放回收等关键技术进行了深入研究并开发了海床基监测系统工程样机。系统结合水声通讯与卫星通讯技术实现了水下监测数据的实时传输;在水下集成平台的设计上采取了防拖网、防泥沙等安全性和环境适应性措施;提出了便于实施海上作业的基于自由下落方式的布放方法和基于声学释放技术的回收方法。经过海上长期试验表明该系统能够稳定可靠地在恶劣的海底环境中完成长期监测工作。

The working principle and construction of a seabed based automatic environmental monitoring system are introduced,which could serve in the shallow sea（100 m）.Based on the research of key technologies such as underwater monitoring system and data sampling and transmission,the engineering prototype system is developed.Acoustic communication and satellite communication technologies are integrated in this system to realize real-time data transmission of the underwater system.The structural design of the system gives it better security and adaptability in the case of trawling or silt covering.The system could be deployed with free-falling manner and be withdrawn conveniently under the control of an acoustic releaser.Long-term ocean experiments have been carried out to test and verify the technologies mentioned above.
