一种基于船用无线电台的新型数据通讯网络系统

New data communication network system based on the marine radio

传统无线电台实现数据通讯,主要是利用少数具有辅助功能口的电台,限制了普通型无线电台的利用.基于船用普通型无线电台,提出一种新型的数据通讯实现方案,不依赖电台辅助功能口,且在传输信号处理上采用了数字滤波、Modbus协议编码等技术及海域电子地理信息等系统构成了功能强大的数字通讯平台,实验结果证明方案可靠、实用.

The data communication is only realized by a few radios with the assisted functional interface. So the utilization of the traditional radio is confined. Based on the marine radio, a new scheme of achieving the data communication is carried out without relaying on the assisted functional interface. With the data filtering technique, Modbus protocol coding technique and the ocean electron geographical information system etc., we form a new powerful data communication system. The results demonstrate the reliability, practicality of the scheme.
