【摘要】：目前,VTS的VHF通信子系统的构成方式主要采用专用岸台设备,以线路交换的方式构成VTS的VHF通信网,这种VHF系统存在着工程造价高、管理维护成本高、可持续性差等问题。近年来,基于VoIP技术的分组交换VHF网也应用于VTS,但由于是采用专用设备构成,其仍然存在着工程造价高等问题,此外,由于在系统构成上采用商用VoIP设备和软件,未针对VHF通信操作的特点进行技术的相应改进,导致话音与控制不同步而丢失话音以及话音质量有时很差的问题的产生。本文在“宜昌VTS工程枝城大桥和巴东水域VTS站”项目(合同标号：’20102942)经费支持下,研究了一套基于船用VHF设备,利用VoIP分组网实现的VTS的VHF通信子系统。(1)本课题主要研究对VTS系统中的VHF通信设备的改造,利用嵌入式技术对传统船用VHF设备进行改造,改造后的船用VHF收发设备可以实现对模拟语音信号的数字化处理和传输,使得船用VHF设备可以适用于VTS的VHF子系统,实现船用VHF设备的交管化。(2)利用当下流行的VoIP分组网传输技术使收发信机能够通过局域网有效、准确地与各VHF操作终端之间进行信息的交换,实现交管化设备的联网通信,提高了海上船舶之间、船岸之间以及基站与VTS中心之间的通信质量。(3)通过解析船用VHF设备的控制信号,在Visual Studio 2008编程环境下完成VHF操作终端的通信面板设计,实现VTS中心操作人员对远程基站设备的遥远控制。(4)构建一个双机互联系统,实现一台收发信机设备联网控制,检验船用VHF设备改造方案的正确性和可行性。
[Abstract]:At present, the VHF communication subsystem of VTS is mainly composed of special shore station equipment and VTS VHF communication network by the way of line exchange. This kind of VHF system has the problems of high project cost, high cost of management and maintenance, poor sustainability and so on. In recent years, the packet-switched VHF network based on VoIP technology is also used in VTS. However, because of the use of special equipment, it still has some problems such as high engineering cost. In addition, because of the use of commercial VoIP equipment and software in the system structure, Due to the lack of technical improvement on the characteristics of VHF communication operation, the problem of voice losing and voice quality being sometimes poor is caused by the non-synchronization of voice and control. Supported by the project "Zhicheng Bridge of Yichang VTS Project and VTS Station in Padang Waters" (contract No.: 20102942), a set of marine VHF equipment is studied in this paper. The VHF communication subsystem of VTS realized by VoIP packet network. This paper mainly studies the transformation of VHF communication equipment in VTS system, and uses embedded technology to transform the traditional VHF equipment. The modified marine VHF transceiver can realize the digital processing and transmission of analog voice signal, which makes the marine VHF equipment suitable for the VHF subsystem of VTS. Realizing the traffic management of the marine VHF equipment.) using the current popular VoIP packet network transmission technology, the transceiver can exchange information with each VHF operation terminal effectively and accurately, and realize the network communication of the traffic management equipment. The communication quality between ship and ship, between ship and shore, between base station and VTS center is improved. By analyzing the control signal of marine VHF equipment, the communication panel of VHF operation terminal is designed in Visual Studio 2008 programming environment. The remote control of remote base station equipment by operators of VTS center is realized. A dual computer interconnection system is constructed. The network control of a transceiver equipment is realized, and the correctness and feasibility of the modification scheme of marine VHF equipment are verified.
