Design Of Tilting Control Maintaining System For Tilting Train

In order to improve the speed of passenger train in the mountainous area, the tilting train is an effective way in existing curve railway, which is adapt to the situation of our country. For the tilting train has advantage of increasing train speed in curve railway, the tilting control system supported by the R&D Program of Ministry of Railways of China is passed in 1999.The tilting control system is the key technology of tilting train, whose safety is important for tilting train to run normally. According to the characteristic of tilting control system, the tilting control maintaining system is developed in order to provide the applying department with the safety maintaining means. The system has good effect to enhance the tilting train's safety and service, improve tilting train applying efficiency and decrease maintaining time.Firstly, development and present condition of titlting train's research and the equipment maintenance is introduced, which is being developed in our country. Moreover the structure and working principle of tilting control system is presented, with the testing subsystem, control subsystem, communication subsystem and tilting actuation subsystem discussed particularly.Secondly, considering the tilting train applying complexion and analyzing the debugging system function, the hardware of tilting control maintaining system is designed, with circuit working principle and main devices described in detail. In the design of the software, the basic knowledge of serial communication is introduced, and the program flow chart of Intel 8031 is presented. Next the characteristic of serial communication in the condition of Visual Basic 6.0 is discussed, the tilting train maintenance software is programmed by Visual Basic 6. 0.At last, the test of tilting control maintaining system is discussed. According to the result of test, the system works well andmeets the requirement of the tilting train maintenance, which lays the theory and testing foundation for the tilting train application in the future.
