摘要
内河船舶的运行状态信息、船载货物(尤其是危险品货物)的状态信息对保证船舶的航行安全极其重要。由于受到船舶钢质船体和内部特殊结构的限制,造成有线网络的电缆敷设十分困难,无法对上述信息进行高效采集和传输。提出建立基于自组织通信技术的船舶内部感知网络系统,对系统结构进行设计,并从船舶无线传感器网络节点、自组织路由算法的关键技术、基于无线传感器网络的船舶运行状态信息采集和传输技术、智能船载终端四个方面开展研究。最后的实船测试表明在船载环境下利用传感器采集船舶运行状态信息及货物信息是可行的。
The navigational status information of the inland ships and cargoes carried(especially dangerous goods) are extremely important to ensure the navigational safety of ships.However,the restriction of the ship's steel hull and the ship internal special structures make cable laying of wired network and using sensors to collect and transmit information very difficult.This paper attempts to build a ship internal sensing network system based on self-organizing communication technologies.Firstly,we proposed the system structure in this paper.Research was carried on from four aspects;including ship wireless sensor network node,the key technology of the selforganizing routing algorithm,the collection and transmission technology of navigational status information based on wireless sensor network and ship-borne intelligent terminal.To verify the feasibility of the technologies described,a real ship test was accompanied.Findings from ship's tests show that it is feasible to make use of sensors to collect navigational status information and cargo information.
