分布式海上AIS通信与监控平台设计

Research and implementation of distributed marine AIS communication and monitoring platform

自动识别系统(AIS)是当前常见的助航设备之一。通过AIS船舶能够向周边水域的船舶或管控中心通报自身的位置、速度、航行等信息,并能够实现相互的通信协作,大大提高了船舶航行的安全水平,是当前港口管理、航道管制等业务必不可少的系统之一。然而,传统的AIS在使用过程中采用网络点对点的通信方式,中心化的组网模式大大降低了通信效率和消息协作的效能。为解决这一问题,本文提出一种分布式海上AIS通信与监控平台,研究该平台的架构和工作方式,同时设计相应的控制算法和通信协议,为进一步完善AIS系统提供依据。

Automatic identification system （AIS） is one of the current common navigational AIDS. Through the AIS ship can inform ships surrounding or control center of information such as position, speed, navigation, and can realize the mutual communication collaboration, which greatly improve the safety level of the navigation of ships. AIS is the current port management and channel control system of the business. However, the traditional AIS uses the point-to-point communication mode, which has a centralized topology and greatly reduce the efficiency of the communication and cooperation of message. To solve this problem, this paper proposes a distributed marine AIS communication and monitoring platform. The platform is studied architecture and works, and design the corresponding control algorithms and communication protocols, provides the basis for further perfecting the AIS system.
