中文摘要：

针对传统船载货物监控成本高、数据可信度低、系统不易拓展的现状,设计了船载货物的海事监控传感网络系统。系统由基于无线传感器网络的船载监控网络、基于通用分组无线业务技术（GPRS）的公共移动通信网络和基于浏览器/服务器（B/S）模式的上位机监控平台组成。船载监控网络采用分层的网络拓扑结构、自适应成簇算法、统一的通信协议,终端节点采用休眠/激活机制,提高了网络的健壮性和寿命。GPRS网络能将紫蜂（ZigBee）网络采集的传感信息及时投递至远程服务器,监控中心人员通过浏览器即可查询货物各方面的状况。本系统在实验测试中表现出性能稳定、实时性强、数据可靠性高等特点,可为类似研究提供一定参考。

英文摘要：

In view of the high costs,low data believability and limited functionality of existing methods for shipborne cargo monitoring,a new system based on the sensor network is developed.The system consists of a shipborne wireless sensor network for cargo monitoring,a PC monitoring platform based on B/S mode and a ship to shore link over the GPRS public mobile communications network.In the design of the shipborne monitoring network,the hierarchical structure of network topology,the absorbing adaptive clustering algorithm,the unified communication protocol and the end device sleep / activation mechanism are adopted to improve the robustness and working life of the network.The GPRS network can deliver the data collected by ZigBee network to remote servers in realtime,and the personnel at the surveillance center can check cargo status with a browser.The experment shows that this system has the advantages of stable performance,good real-timeness,high data reliability etc.and can be a base for further development.
