脉冲轨道电路脉冲源的研究与仿真

考虑脉冲轨道电路脉冲源脉冲周期1/3s对轨道电路的应变时间稍慢,而提出实现脉冲轨道电路脉冲源脉冲周期1/4s,并采用脉冲波形时间为40ms,恰为25Hz周期的脉冲源仿真,从而达到更好地兼容25Hz轨道电路设备。更好地实现既有25Hz轨道电路叠加电码化改造脉冲轨道电路叠加电码化。

Research and Simulation of Impulse Source of Impulse Track Circuit

It is considered that the response time to the track circuit will be slower if the pulse cycle of impulse source is 1/3 second,so the paper proposes that the pulse cycle is changed to 1/4 seconds with the pulse waveform time of 40ms,which is exactly impulse source simulation of 25Hz cycle,and has good compatibility with 25？Hz track circuit equipment.As a result,the overlap impulse track circuit can be easily achieved based on existing overlap 25Hz track circuit.
