【摘要】 论文是基于轨道交通实验系统而展开的,该系统是现代高校教学迫切需要的设备,该设备可以加深学生对理论知识的理解,提高学生实际操作的能力。轨道交通实验系统主要由三个部分组成:显示终端、控制系统和仿真沙盘设备。论文中对轨道交通实验系统的控制系统做了研究与设计,其中硬件方面包括控制系统中输出部分的开关量功率输出板和功率输出板的测试电路的设计,高频轨道电路板的设计与实现。同时提出了输入卡PCI专用接口芯片的设计方案。软件方面编写了功率输出板的测试程序,利用Socket实现了功率输出板测试程序与站场界面的通信功能,并且设计高频轨道电路的仿真电路并对其进行仿真分析与实际测试。通过实际调试已经完成了控制系统的预期设计功能,在轨道交通实验系统中得到了成功的应用。更多还原

【Abstract】 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.更多还原
