The invention discloses a track circuit system which comprises a state monitoring circuit of a track circuit. The state monitoring circuit comprises a first signal acquisition unit, a second signal acquisition unit and a processing unit connected with the first signal acquisition unit and the second signal acquisition unit. The first signal acquisition unit is used for acquiring difference voltage between a sending matching transformer and a receiving matching transformer in the track circuit to obtain a matching difference signal; the second signal acquisition unit is used for acquiring the difference voltage between the transmitting lightning protection transformer and the receiving lightning protection transformer in the track circuit to obtain a lightning protection difference signal; and the processing unit is used for determining the current state of the track circuit according to the balance degree between the matching difference signal and the lightning protection difference signal, that is, fault inspection of the track circuit can be effectively realized by monitoring the balance degree of a transmission channel of the track circuit, and the problems that the existing scheme is easily restricted by the sampling precision of key electrical parameters, and the reliability is high are solved. And the state monitoring accuracy is low.

    本申请公开了一种轨道电路系统、轨道电路的状态监测电路,该电路第一信号采集单元、第二信号采集单元,以及分别与第一信号采集单元和第二信号采集单元均相连的处理单元;第一信号采集单元用于对轨道电路中发送匹配变压器与接收匹配变压器之间的差异电压进行采集,得到匹配差异信号;第二信号采集单元用于对轨道电路中发送防雷变压器与接收防雷变压器之间的差异电压进行采集,得到防雷差异信号;处理单元用于根据匹配差异信号与防雷差异信号之间的平衡度,确定出轨道电路的当前状态,即本案可以通过监测轨道电路传输通道的平衡度,有效实现轨道电路的故障检查,解决了现有方案容易受到关键电气参数采样精度制约,导致状态监测准确度低的问题。
