The Research Of Control System For Railway Transportation Experiment

This paper is based on the study and development of railway transportation experiment system, which is urgent needed by college education . This equipment can deepen the comprehension of the students' theory knowledge and improve their practice ability.The railway transportation experiment system consists mainly of three part as the display terminal, control system and simulating sand table equipment. Here the control system of railway transportation experiment platform is studied and designed, including square wave power output board of the control system along with the testing circuit of the power output board and the high frequency circuit design and implementation. Meanwhile, a design plan is proposed for the PCI interface circuit of the signal input board. The testing program for the power output board is composed while the communication function between the testing program and the railway station virtual interface is realized using Socket technology. The simulation circuit of the high frequency circuit is designed, analyzed and taken to practically tested.The control system now fully meets the design requirements after in place debugging and is successfully applied into the railway transportation experiment system.
