外文摘要：The real-time online offshore monitoring system based on wireless sensor network has been designed. It successfully applied wireless sensor network technology to the field of ocean environmental monitoring system. The system is an automatic monitoring system without manual involvement,which runs automatically by the program from the data collection nodes import to the sink node through the communication nodes. The handheld sink has a slick looking interface. It is an offshore wireless sensor networks which can be set up flexibly and can monitor the changes of temperature,light intensity,PH, dissolved oxygen and other parameters. The system is composed of three main components including data acquisition subsystem,data transmission control subsystem and data sharing subsystem. The subsystems are responsible for monitoring data collection,information transmission processing,data sharing,and information service. This paper described the architecture of the entire system and the implementation of each module in details,especially the implementation of data acquisition subsystem including hardware packaging,software designing and environmental configuration. Through analyzing of telos node hardware and the energy status of routing protocols, it proposes energy-saving solutions based on energy-efficient routing and radio dormancy strategy. The system has been running for more than one year. It has been proved that the system is energy-saving. It has made an important impact on ocean ography.
