Abstract: 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.

Key words: intelligent winch; real time observation; profile observation; TCP/IP architecture
