Design of the Power System and Remote Control System for the Unmanned Ship

Abstract In lakes and reservoirs with high environmental protection requirements, it is necessary to adopt pure electric intelligent water quality monitoring ships, adopt pure electric power systems and intelligent remote control systems. This article specifically completed the design of the power system and remote control system of the smart ship, and elaborated the design method in detail. The system has the characteristics of high reliability, miniaturization, and modularization. The successful development of the system has greatly improved the intelligence of water quality monitoring ships, and has a positive effect on small intelligent ships in lakes and reservoirs.

Water quality monitoring plays an important role in contamination control and environment protection. This paper describes an on-line multiparametric water quality monitoring system based on visible spectrophotometry, which combines embedded technology with GPRS telecommunication technology. This system can realize online wireless monitoring to concentrations of chromium (Cr), plumbum (Pb), A surfactant (AS), chemical oxygen demand (COD), ammonia nitrogen (AN), total phosphorus (TP) and total phenol (TPh) in real time. The mechanical structure, hardware circuit and software design of the system are completed. The absorption spectrums of pure water and MB-SDS complex have been measured. Preliminary experiments using a model machine show that each mechanism of the system runs well. Moreover, the monitor possesses many advantages, such as high degree of automation, high reliability, high efficiency, compact structure, small size, and so on.

In the case of hydraulic power system of ships or marine facilities, many kinds of mechanical, electrical, hydraulic components are connected to each other very complicatedly. It is very hard to disassemble or reconfigure the hydraulic system. Therefore there are increasing demands from industry for a stand-alone type actuator and a valve remote control system. Valve remote control system (VRCS) is a convenient system which it possible to operate the valves installed in the cargo or ballast tanks from the remote wheelhouse. This paper is dealing with a new stand-alone type hydraulic actuator for a valve remote control system. The stand-alone type hydraulic actuator consists of a gear pump, an AC motor, a check valve, a relief valve and a controller. We try to design and implement the stand-alone type hydraulic actuator and this tries to be verified through an experiment. This research is a contribution to simplify a hydraulic system, improve responsibility of dynamic power system, and reduce an energy loss in a ships or marine facilities.
