Design Of Tilting Control System For Tilting Train Based On PC/104

To speed up passenger trains and decrease journey time are one of the targets of the world railway modernization, and also a means to increase competition in transportation market. In our country, many railway lines which were built in mountainous area have heavy gradient and curves with small radius. So it is difficult to improve them and a great amount of cost is needed in the modification of them.The use of tilting trains can raise curving speed effectively, so some countr ies take advantage of the tilting passenger rol 1 i ng stock to speed up trains that run on existence lines. The tilting control system of ti1ting trains is the key of the ti1ting trains ' successfu1 application. There are several kinds of tilting control system of tilting trains. Positive tilting, real-time measurement and the compensation of gyroscope are the development trend of the tilting control system.In this paper, several kinds of tilting control system were presented and analyzed. According to the development condition of the tilting control system in our country, the design of the tilting control system based on PC/104 was brought forward. The control network-LonWorks was applied to the design.The function and principle of all components of tilting control system such as detection subsystem, control subsystem and tilting actuation subsystem were illustrated in the paper. The design of the communication interface card between PC/104 and the control network-LonWorks was set forth in the paper. The design of interface program, data collection program, digital filter program and the interface program of network were described in detail in the paper. The control strategy of the tilting control system was emulated in the paper. The tilting control system was tested in the paper.The foundation of designing methods of real i ty ti1ting trains with tilting control system was set up, through theory research and experiment on it.
