According the new ship building tense, a novel electric propulsion simulator (EPS) had been developed in Marine
Simulation Center of SMU. The architecture, software function and FCS network technology of EPS and integrated
power system (IPS) were described. In allusion to the POD propeller in ship, a special physical model was built. The
POD power was supplied from the simulative 6.6 kV Medium Voltage Main Switchboard, its control could be realized in
local or remote mode. Through LAN, the simulated feature information of EPS will pass to the physical POD model,
which would reflect the real thruster working status in different sea conditions. The software includes vessel-propeller
math module, thruster control system, distribution and emergency integrated management, double closed loop control
system, vessel static water resistance and dynamic software; instructor main control software. The monitor and control
system is realized by real time data collection system and CAN bus technology. During the construction, most devices
such as monitor panels and intelligent meters, are developed in lab which were based on embedded microcomputer
system with CAN interface to link the network. They had also successfully used in practice and would be suitable for the
future demands of digitalization ship.
In view of the existing issues on extraction of GIS vector data from maps, we propose an image recognition method based on wavelet transformation. Using the method, we first made the wavelet transformation of a color urban traffic map and took the value near zero points of the wavelet coefficient, and then, color model transformation was adopted to obtain a gray image. Afterwards, an appropriate threshold was chosen and the gray image was transformed into a bilevel image. In the end, the erosion algorithm in the mathematical morphology was used to thin the image in order to identify the road information. The experimental result showed that the method could be used to effectively identify the road information from an urban traffic map.
Developing multi mode MER (Marine Engine Room) Labs is the main work in Marine Simulation Center, which is the key lab of Communication Ministry of China. It includes FPP (Fixed Pitch Propeller) and CPP (Controllable Pitch Propeller) mode MER simulation systems, integrated electrical propulsion mode MER simulation system, physical mode MER lab, etc. FPP mode simulation system, which was oriented to large container ship, had been completed since 1999, and got second level of Shanghai Municipal Science and Technical Progress award. This paper mainly introduces the recent development and achievements of Marine Simulation Center. Based on the Lon Works field bus, the structure characteristics and control strategies of completely distributed intelligent control network are discussed. The experiment mode of multi-nodes field bus detection and control system is described. Besides, intelligent fault diagnosis technology about some mechatronics integration control systems explored is also involved.
