| 摘 要： | 数字通信技术是未来信息传输的发展方向。我国目前所用的船舶水下噪声测量系统的数据传输主要采用模拟传输技术,存在较多弊端。本文所介绍的是采用数字通信技术实现船舶水下噪声测量的数据传输。主要是采用RS-485总线标准作为接口技术,以半双工的通信方式,通过一根同轴电缆作为数据和电源信号同步传输的介质,实现了水下长距离、高速率的数据传输。

| Abstract: | The digital communication technology is tendency of the development about information transmission in the future.In our country,data transmission for noise measuring and analyzing system of ship existed today apply mostly anolog transmission mode,which exists some disadvantage.In this article,we introduce the digital communication technology which accomplish data transfers in the underwater ship noise test.It utilizes chiefly RS-485 bus standard as interface and half-duplex communication mode.In a coaxial-cable,which becomes communication medium for data and power signal to transmit synchronously,we achieved long distance and high speed underwater data transmission. |
