Set Of Deep-sea Mining Machine Communication With The Water Monitoring System Research And Development

Deep-sea mining of minerals like manganese nodules has been one of the challenging tasks facing ocean engineering in the 21^th century, and one of significant domains of the high science and technology development in maritime industry. It is, currently, an important task to develop a steady supervisory system on data-acquisition, remote communication and control.The communication and supervisory system in mining-ship on the ocean is mainly to monitor and control the working condition of the deep-sea mining collector. In this dissertation, the design method and implementation approach of the communication and supervisory system are in detail introduced for matching 1000m-depth-trial in the ocean. The components and operating principle of supervisory system are analyzed, and the data-acquisition flow charts are proposed. To meet the demand of the trial and for extensibility of this system, the transmission system that is long-distance, high-bandwidth by optical fiber is designed at length. Time-division multiplexing and wavelength-division multiplexer respectively design the protocol of communication and the configuration of intercommunication, between the above-water workstation and underwater workstation; the data frames structure that is easy to branch connection is put forward. Based on object-oriented design, the software of supervisory system is developed, and it is sovled that the control periods are not consistent with the time of data-acquisition.The method for the design and implement of the communication and supervisory system of the deep-sea mining collector influences on the design, operation and control of the mining system directly, which would be, certainly, helpful for the further research and development of the deep-sea mining technology.
