| On this paper, for assuring ship-gate system running safely in the future, some key technologies must be studied in advance, such as, reliability on control system scheme~. simulation and showing image of running system, so the following work must be researched:1.Firstly reliability of five-step ship gate control system scheme is Analyzed Applying Fault Tree Analysis(FTA), obtaining fault trees , and on the base of the trees, Mean Time Between Fault(MTBF) of different control schemes is calculated, at last several important points helping to reliability of system are obtained.2.Based on continuous model and discrete model of control system, simulation technology is studied, finally curves about water level and journey of ship are drawn and probability of using is calculated.3.Based on continuous model and discrete model of control system, demo system of five-step ship gate control system is developed by means of Visual Basic6.0,which can show ship gate running to the life in the course of nature and at the time of fault. |
