Design for Power Distribution & Control System of OMAS
One Man Atmospheric System (OMAS), is an articulated anthropomorphic single person submersible which consists of the Suit, Tether Management Systems (TMS), Launch and Recovery Systems (LARS) and Surface Control Systems (SCS). The submersible is presently capable of allowing a pilot to operate at the worksite. OMAS maintains the internal pressure at one atmosphere. There is no need for decompression schedules and it increases the bottom times. Meanwhile, the pilot is put directly at the worksite where they can observe dexterously and control tools directly. So OMAS are most effective. The images in operation which are transferred synchronously to the surface can be used to monitor and guide the operation. Power Distribution & Control System is the most important system for OMAS. It is charged with power distribution of Suit, TMS and SCS, controlling navigating and working for OMAS. It also provide the channel for exchanging of information, the display and alaming for OMAS. According to physical location, control system is divided into three parts: surface control, TMS control and suit control. And these three parts functionally response their own control requirements. Firstly, this paper introduce the general situation of OMAS. Secondly, the design for power distribution & control system of OMAS is provided. Then, debugging for the system, situation of pool trial and sea trial are given, controlling system is improved through pool trial and sea trial. At last, summarize the design for power distribution & control system. Finally, at the end of the paper, and with the benefit of many years experience of underwater technology, some advice is presented.
