摘要
针对目前海洋物理参数、高清视频实时观测的需求,对基于LTE技术的PLC远程控制、视频流式传输及分发等技术进行了研究,对自动排缆绞车、基于状态机的绞车控制软件、兼容远程和手动控制的绞车电气系统、数据服务器等内容进行了设计,提出了一种基于智能绞车的水下剖面观测系统。智能绞车采用TCP/IP架构,可实现远程控制或自主运行,使用绞车牵引传感器运动的方式替代了传统的拖曳多套传感器或固定点方案。利用岸基测试平台和船只对系统进行了多次测试。研究结果表明:该系统能够实现多终端实时观看水下多种数据和高清视频、远程控制设备升降等多项功能,具有观测范围广、可移动性好的特点,适用于海洋物理参数、高清视频的大范围立体在线观测。
Aiming at the needs of real-time observation of marine physical parameters and high definition video,the PLC remote control based on LTE technology,video streaming transmission and distribution technology were researched. The content of the winch compatible with automatic cable arranging,the control software based on the state machine,the electric winch system compatible with remote and manual control,and the data server were designed. A kind of underwater profile monitoring system based on intelligent winch was proposed. The intelligent winch adopts TCP/IP architecture,it could realize remote control and automatic operation. The winch drew sensors were used to realize profile motion,instead of traditional drawing multiple sensors or fixed point observation. System was tested in the shore based test platform and ships. The results indicate that multi-terminal real-time data and high-definition video watching,remote control equipment lift and some other functions are realized,system has the characteristics of large observation range,good mobility. It can be applied to the large scale stereo online observation for ocean physical parameters and high definition video.
