The invention relates to a method and device for detecting poor shunting of a track circuit, and belongs to the technical field of railway signal maintenance. According to the technical scheme, a detection operation device walks on a track, and the shunting state of a train detection track circuit is simulated by short-circuiting the track circuit; a detection body collects shunt voltages in time through a voltage sensor, then amplifies signals through an amplifier, compares the amplified signals with a set value, and if the actual value is higher than the set value, the detection body does not change. And if the actual value is lower than the set value, the detection body sends a sound-light alarm through the alarm module to prompt that the shunting of the track circuit is poor. The method has the advantages that whether faults of poor shunting of the track circuit exist in different track sections or not can be timely and accurately diagnosed, the names of the poor shunting sections of the track circuit can be locked, and therefore the safety of driving operation and the right point of pulling and exchanging operation are guaranteed.
本发明涉及一种轨道电路分路不良的检测方法及装置,属于铁路信号检修技术领域。本发明的技术方案是:检测运行装置在轨道上行走,通过对轨道电路短路从而模拟火车检测轨道电路分路状态;检测本体通过电压传感器及时收集分路电压,然后通过放大器对信号进行放大,放大后的信号与设定值进行对比,若实际值高于设定值,检测本体不发生变化;若实际值低于设定值,检测本体通过报警模块发出声光报警提示该处轨道电路分路不良。本发明的有益效果是:不但能够及时准确的确诊不同轨道区段是否存在轨道电路分路不良的故障,而且能够锁定轨道电路分路不良区段名称,从而保证行车作业安全,拉兑作业正点。
