| 摘 要： | 目前,深海科学考察所用的调查设备动力与监控系统的供电电源主要采用水下锂离子电池供电,但采用锂离子电池供电存在较多弊端，严重制约着深海科考工作的发展。本文针对这个弊端设计并制作了数据耦合器，实现了基于铠装同轴电缆的能源、彩色实时图像以及上、下位机数据的混合传输。该技术主要采用低通滤波和电容耦合，将数据信号叠加到电源信号上，通过同轴电缆，实现长距离功率能源与数据混合传输。

| Abstract: | Nowadays research device and monitoring system are often powered by underwater lithium batteries.Using underwater lithium batteries has so many disadvantages that it actually constrains the development of deep-sea scientific research.The authors propose a new mixed transmission technology based on the armored coaxial cable,which they have realized.This new technology can transfer direct-current high power source,real-time color image and data of both host and slave at the same time.It makes the superpositio... |
