摘要
"分路不良"和机车信号"掉码"是目前无绝缘轨道电路(Jointless Track Circuit,JTC)分路状态亟需解决的问题.为此,根据列车各轮对位置和编组结构,并考虑JTC钢轨与道床的漏泄,采用传输线六端口网络理论,对列车"仅占用接收端调谐区"、"占用接收端调谐区和主轨道"、"仅占用主轨道"、"占用主轨道和发送端调谐区"和"仅占用发送端调谐区"5个场景下的主、小轨道接收器分路残压和机车信号感应电压进行建模.实验表明:本文模型的仿真结果与实际数据更为接近,可为以上问题的研究提供良好的理论支持.
“Bad shunting” and “code dropping” of locomotive signal are the problems that need to be solved urgently in the shunting state of jointless track circuit at present. For this, according to the position of wheelset and organization structure of train and considering the leakage of JTC rail and ballast bed, the theory of six-terminal network of transmission is used to model the shunt residual voltage of main and small track receivers and the induced voltage of locomotive signals in five scenarios of train “occupying only the tuning area of receiving end”,“occupying the tuning area of receiving end and the main track”,“occupying only the main track”,“occupying the main track and the tuning area of transmitting end” and “occupying only the tuning area of transmitting end”. Experiments show that the simulation results of this model are closer to the actual data, and it can provide good theoretical support for the research of the above problems.
