通用自动识别系统监控终端的研究与实现

船载AIS是一个通过VHF无线电自动在船舶之间以及船岸之间交换船舶信息和导航信息的系统,这些信息包括船位、航向、船名等静态和动态信息。整个系统是为海上交通控制和安全服务的。但是,我国船上安装的AIS设备的基本都是国外设备。通过对国外进口AIS系统主机与监控终端通信协议的解析,并结合实际需求详细设计了AIS监控终端。实现了监控终端对AIS收发机的控制以及AIS收发机发来信息的显示,整个设计符合AIS系统的要求。同时,对监控终端的硬件进行电磁兼容优化设计,提高抗干扰能力。现场运行结果表明,该监控终端长期运行稳定可靠。

Research and Realization of UAIS Monitor Unit Based on SOC

An automatic Identification System(AIS) enables ships to exchange static and dynamic information about ships and navigation,such as position,course,name etc.automatically by VHF radio.The system is bound to contribute to improvement of marine traffic control and safety.To develop AIS of own is important.This paper analyses the communication protocol between the AIS transponder and the monitor unit,and gives the design of monitor unit in detail.The whole design accords with the requirements of AIS.The hardware optimization design of the monitor unit for AIS is carried out with electromagnetic compatibility technology to enhance the anti-interference ability.The result of spot test indicates that the monitor unit for AIS can work stably for a long time.
