Abstract: With the construction and development of high-speed railway in our country, the train has introduced more automation systems, and the data transmission between these systems needs to rely on more digital, network technology, related filters, waveform generators and other equipment. At present, railway communication frequency modulation signal is used 2 frequency shift keying in our country, the signal includes modulation and demodulation of the two steps to achieve a stable transmission of railway signal, to ensure the normal development of railway information work. This paper analyzes the application of 2FSK in railway signal, and provides a modern multimedia image, which realizes remote control function and facilitates human-computer interaction.
Key words: railway signal; modulation and demodulation; 2 frequency shift keying |
