| Abstract: | It was researched on method of safety transmission for data of radio cab signal. According to the demand for data transmission of radio cal signal and based on the GSM-R data channel structure and security transmission protocol, it was proposed some methods which was included address-time-key three-dimensional control, time-division multiplexing communication method and communication protocol, variable frame structure and so on. It was prevented the problems caused of wireless interference, and the conflict of frame data transmission error, insured the reliability and security of data transmission for radio cab signal. |
