Design And Realization Of The Recording And Analyzing System About Railway Signalling

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.
