摘要
为了提高船舶运行的稳定和安全性,需要对船舶的运行状态进行实时监测,设计无线网络下船舶运行状态远程监控系统,系统包括船舶运行状态特征采集模块、AD转换模块、总线传输模块、无线网络通信模块、集成控制模块和人机交互模块等,采用远程卫星通信和无线传感器网络组网技术进行船舶通信网络构建,基于H.323协议和IETF的SIP会话初始化协议进行船舶无线网络通信的信令设计。采用多点多线程控制方法进行船舶运行状态的监控指令的集中执行,在集成GCC编译环境中进行监控系统的应用程序开发和交叉编译,采用异构、层次化的中间件技术进行监控系统的软件平台设计,实现船舶监控系统的网络接入服务和状态实时监控服务。系统测试结果表明,设计的船舶运行状态远程监控系统能实时监测船舶的运行状态特征,系统自适应性和可靠性较好。
In order to improve the stability and safety of ship operation,real-time monitoring to running state of the ship,a ship remote monitoring system,the running state of the design of wireless network system,including ship operation state feature acquisition module,AD conversion module,bus transmission module,wireless network communication module,integrated control module and human-computer interaction module.Ship communication network using remote satellite communications and wireless sensor networking technology,SIP session initiation protocol H.323 protocol based on IETF and wireless network communication for ship design.Focus on the implementation of the multi thread control method for ship operation state monitoring instruction,monitoring system application development and integration in cross compiler GCC compiler environment,design software platform monitoring system using heterogeneous and hierarchical middleware technology,network access services and real-time monitoring service ship monitoring system.The system test results show that the designed remote monitoring system of ship running state can monitor the running state characteristics of ship in real time,and the system has good adaptability and reliability.
