The invention discloses a method and a system for 50Hz track signal detection and state identification, which belong to the technical field of track circuit microelectronic receivers. The method comprises the following steps of: sampling and filtering an externally input track voltage signal to obtain an effective sampling value of a track voltage; performing voltage calibration on the track voltage effective sampling values sampled by two CPUs, and calculating to obtain a track voltage actual value; performing 2-vote-2 comparison on the track voltage actual values of the two CPUs to obtain a2-vote-2 comparison result of the track voltage actual values; and based on the 2-vote-2 comparison result, identifying the track state. The method is good in expandability and convenient to maintain,the track state can be identified in real time, and the track state identification accuracy is high.

    本发明公开了一种用于50Hz轨道信号检测及状态鉴别的方法及系统,属于轨道电路微电子接收器技术领域,包括:对外部输入的轨道电压信号进行采样滤波处理,得到轨道电压的有效采样值;对两个CPU采样的轨道电压有效采样值进行电压标定,经过计算得到轨道电压实际值;对两个CPU的轨道电压实际值进行二取二比较,得到轨道电压实际值的二取二比较结果;基于二取二比较结果,对轨道状态进行鉴别。本发明可扩展性好,维护方便且可实时鉴别出轨道状态,轨道状态鉴别准确率较高。
