采用无线机车信号系统实现机车信号主体化

提出采用无线机车信号系统实现机车信号主体化。该系统的主要优势在于利用无线信道方式传输机车信号、列车位置、速度等列控信息,构成信息传输闭环确认,保证信息传输的可靠性;无需进行车站电码化,不存在因轨道电路受干扰影响信息传输问题;最大限度利用既有地面信号设备和车载列控设备;系统结构简单,便于实现,成本低。阐述了系统的基本结构和工作原理。对系统中的无线机车信号、无线数据传输等关键技术进行了重点描述,并对系统的故障-安全进行了分析。

In this paper, it is proposed that Radio Cab Signal be adopted to realize the Authorization of Cab-Signaling. The major advantages of this system lie in an easy construction of a closed-loop of infor-mation transmission of such train control data as cab signal, the position and speed of a train, ensuring the reliability of information transmission. There is no need for station coding and no data transmission problems due to track circuit being interfered. Existing ground signal equipment and on-board equipment could be employed to the greatest extent. The structure of the system is simple, easy to realize, and with low cost. The basic structure and working principle of the system is introduced in this paper. The key techniques of the system, such as the radio cab signal, wireless data transmission method and so on, are highlighted and the fail-safety of the system is also analyzed.
