摘　　要：研究采用无线信道方式传输数据,实现机车信号数据安全传输的方法。根据无线机车信号数据传输需求,以GSM-R数据通道结构和GSM-R安全传输协议为基础,提出采用地址、时间、注册码三维控制、时分复用通信方式和通信协议、帧结构可变、调整优先级等方法。防止由于无线干扰和传输网络帧冲突等原因造成的数据传输错误,保证无线机车信号数据传输的可靠性和安全性。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.
