Information Processing System Of Ship Course/Roll Control System

The complicated variable working condition and circumstance of the sea make Intelligent Information Processing System tedious. How to control ship and process information accurately and conveniently becomes the key point to settle for ship control system. Aiming at the problem mentioned above, an information process system, including software and hardware, is designed for ship course/roll control system to realize complex control algorithm and succinct operation interface.Information processing system of ship course/roll control system is based on the combined controlling model of main/flap rudder angles and main/flap. The control algorithm was proved to be valid by simulation in MATLAB. Then an information processing system based on industrial computer was designed and simulated by C++. The software construction of information processing system was designed under the circumstance VC++.Intelligent information processing system is the core of ship course/roll control system. Based on industrial computer 610H and data acquisition card PCI 1716 and PCI 1723, general scheme for hardware of the system was designed. The data acquisition card was driven and tested, and A/D and D/A conversion in sensor-industrial computer-servo system was realized. According to modular programming thinking, general scheme for software of the system was designed. Algorithm module, man-machine interface module and communication module were called and made practical application of simulating results possible.Intelligent distribution control of main/flap rudder angles and main/flap is the core of information processing system. Based on combined control model of main/flap rudder angles and main/flap and theory of GA, realization flow of information intelligent processing algorithm was designed. According to the designing thought which combines program language and control model, fitness function and various matrixes of intelligent distribution control were decided. Algorithm control program, and driver, interrupt program, and interface program of data acquisition card were developed with Visual C++ 6.0 based on industrial computer and debugging of software and hardware was prepared in this paper. The man-machine interface designed with VC++ permits inputting data by dialog box, saving and reading experimental parameters, and showing results by curves. The industrial computer receives, transforms and calculates signal of sensor, sends control order to servo system and communicates with visual simulation system. Finally, the realization form fits the design goal.
