【摘要】 随着列车运行速度的提高,要求司机按照机车信号指示开车而不看地面信号,这对机车信号工作的可靠性提出100%无误差的要求。机车运行过程的状态监测,对于及时发现和处理信号系统的故障具有重要意义。现有的信号记录设备因为各种原因无法满足现场需求,难以在铁路市场推广应用,因此需要开发出一套制式齐全、携带方便、功能完善的新型产品。本文提出了一种新型铁路信号记录分析系统的设计与实现方法。该系统利用USB2.0进行数据传输,具有丰富的人机交互功能,能对各种制式的轨道信号进行解调,并有效克服传统设备笨重的缺陷。文中提出了新型系统的功能和结构框架并介绍了其硬件实现,给出了系统软件的设计思路和实现方法,最后详细阐述了数据传输的实现方法和可靠性验证。在行车安全日益依赖机车信号的背景下,开发一套能可靠工作的铁路信号记录分析系统具有重要的现实意义和实用价值。更多还原

【Abstract】 With the train speed increasing, it’s required for the motorman to drive according to the direction of cab-signal, rather than the ground signal. It demands a hundred percent preciseness of the reliability while the cab-signal working.Monitoring the state during cab running is of very important significance for detecting and processing the malfuction of signal system.It’s difficult to popularize the present signal recording equipment, for it can’t satisfy the railway requirement with various matters. So it’s desired for a new portable product with complete signal modes, perfect function.A new design and realization method of the recording and analyzing system about railway signalling is presented in this paper. In the system, the transmission of data is completed based on USB2.0, the function of man-machine conversation is perfect, the demodulation of all modes railway signalling is realized, and the unwieldy disadvantage of the present equipment is overcome effectively. In this paper, a new system is presented including its function, structure and hardware realization, the design and realization method of the system software is introduced. At last, the realization method and reliability test of data transmission is described in detail.In the background of train running security depending on cab-signal increasingly, it’s of very important practical significance and value to develop a working reliably recording and analyzing system about railway signalling.更多还原
