Abstract
AIS (automatic identification system) is an advanced maritime navigation system mainly used to improve safety on the sea. It exchanges navigation data with other vessels and with coastal monitoring stations on VHF maritime mobile band. It is based on a self-organized medium access network and relies on the use of a GPS receiver to compute and transmit boat positions. To bring about such a network and ensure its reliability, the nodes must be designed with stringent requirements in mind. In this paper we propose to design and implement the link layer, and therefore the medium access process, of the AIS system. Specification and description language real time (SDL-RT) which is a real time extension of SDL is used to design the system. SDL-RT offers a hierarchical graphical tool which facilities system complexity management, functional testing capabilities and optimized code generation. The generated code is implemented and tested on a digital signal processor (DSP).
AIS(自动识别系统)是一种先进的海上导航系统,主要用于提高海上安全。它通过甚高频海上移动频段与其他船只和海岸监测站交换导航数据。它基于一个自组织的媒体接入网络,依靠GPS接收器的使用来计算和传输船只位置。为了实现这样的网络并保证其可靠性,必须对节点进行严格的设计。本文提出设计并实现AIS系统的链路层,从而实现AIS系统的介质访问过程。系统的设计采用了实时规范描述语言SDL- rt (Specification and description language real time),它是SDL的实时扩展。SDL-RT提供了一个分层的图形化工具,它支持系统复杂性管理、功能测试能力和优化的代码生成。生成的代码在数字信号处理器(DSP)上实现和测试。
