The invention discloses a track circuit monitoring method and system based on redundant data. The method is applied to on-site current monitoring of a track side based on a four-path redundant wiring design. Comprising the following steps: acquiring four paths of current data of a track side based on a four-path redundant wiring design in real time; on the basis of rail side redundant wiring design and current characteristics, rail side current normality or abnormality judgment is carried out by combining four paths of current data; when at least one path of current data is normal, compensating other paths of current data through the normal path of current data by adopting a current compensation method, restoring the other paths of current data into normal current data, and not giving an alarm; when the four paths of current data are abnormal, the rail side current is abnormal, a real value is reported, and an alarm is given; and when the four paths of current data are normal, the rail side current is normal, and no alarm is given. According to the method, the track circuit is accurately monitored and judged, and the number of false alarms generated by station software due to abnormal detection of monitoring equipment is reduced.
本发明公开了一种基于冗余数据的轨道电路监控方法及系统,该方法应用于基于四路冗余布线设计的轨道侧的现场电流监测;包括:实时获取基于四路冗余布线设计的轨道侧的四路电流数据;基于轨道侧冗余布线设计及电流特性,结合四路电流数据进行轨道侧电流正常或异常判断;当至少有一路电流数据正常,则采用电流补偿法通过正常路电流数据对其他路电流数据进行补偿,将其他路电流数据修复为正常电流数据,且不进行报警;当四路电流数据均不正常,则轨道侧电流异常,并上报真实值,且进行报警;当四路电流数据均正常,则轨道侧电流正常,不进行报警。本发明对轨道电路监控判断精准,降低站机软件因监测设备检测异常而产生的误报警数量。
