摘要
以普适计算中智能空间技术应用为背景,分析了智能空间的特征和发展概况,结合船舶物理空间特性提出了船舶智能空间的概念,给出了船舶智能空间的网络架构并对其进行了分析.对船舶智能空间关键技术进行了研究,提出运用LADP方式设置用户访问权限,通过加密和Hash算法建立远程通信安全机制,设置了虚拟场景解读船舶智能空间服务,提出将设备功能抽象为Web服务完成异构网络整合.从大数据时代背景下对智能船舶的定义看,船舶智能空间概念的提出具有前瞻性和合理性,对预测船舶未来发展有一定的参考价值和借鉴意义.
Based on the background of smart space technology applications in pervasive computing,the paper analyses the general characteristics and development situation of smart space,puts forward the concept of ship smart space,discusses key technologies of ship smart space,sets up user's access rights using LADP method. The security mechanism of remote communication is established by encryption and Hash algorithm,the virtual scene is set to explain the nature of the service discovery in intelligent space,and the function of equipment for web services is abstracted to complete the integration of heterogeneous networks. From the definitions of the intelligent ship under the background of the age of big data,the ship smart space built in the paper has forward-looking and rationality,and it has certain reference value and significance for predicting the future development of ships.
