The invention relates to the field of rail transit, and provides a frequency shift pulse rail circuit applied to a heavy haul railway, a control method and equipment, the circuit comprises a first transmitter, an attenuation redundancy controller, a receiver and a communication module, the first transmitter is used for generating a frequency shift pulse mixed signal and sending the frequency shift pulse mixed signal through a steel rail; the attenuation redundancy controller is used for receiving the frequency shift pulse mixed signal and separating the frequency shift pulse mixed signal into a frequency shift signal and a pulse signal; and the receiver is used for receiving the frequency shift signal and the pulse signal, taking the pulse signal as an occupancy inspection signal of the target section, and transmitting a driving signal through the communication module based on the occupancy inspection signal to drive the track relay to act. In the process of judging the occupancy state, only the pulse signal serves as the occupancy inspection signal of the target section, the method can adapt to the lower ballast resistance condition and the longer track section length of the heavy haul railway, and the application requirement of the heavy haul railway is better met.

    本发明涉及轨道交通领域,提供一种应用于重载铁路的移频脉冲轨道电路、控制方法及设备,电路包括:第一发送器、衰耗冗余控制器、接收器以及通信模块,第一发送器用于生成移频脉冲混合信号,并将移频脉冲混合信号通过钢轨发出;衰耗冗余控制器用于接收移频脉冲混合信号,并将移频脉冲混合信号分离为移频信号和脉冲信号;接收器用于接收移频信号和脉冲信号,并将脉冲信号作为目标区段的占用检查信号,还用于基于占用检查信号通过通信模块传递驱动信号以驱动轨道继电器动作。在判断占用状态的过程中,仅将脉冲信号作为目标区段的占用检查信号,可适应重载铁路更低的道砟电阻条件以及更长的轨道区段长度,更满足重载铁路的应用需求。
