A developed Ethernet-based communication system for manned submersible vehicle

Undoubtedly the reliability of inter-communication system for manned submersible vehicle, which is working in dangerous and unforeseeable deep-sea circumstance, is crucial to safety of the overall control system. In this paper firstly, traditional inter-communication system for underwater vehicle (UV) is introduced and it has its intrinsic shortcomings. So in order to overcome those shortcomings a developed Ethernet-based inter-communication system has been designed and implemented. Secondly, various network data transmission delay testing on our semi-physical virtual simulation platform verifies the reliability and its performance of the whole network. And control software is also developed and the results of the auto-heading are shown. At last, the results of analysis and test indicate that this Ethernet-based inter-communication system has a good performance and now we are ready to sea experiments for the future.
