The invention relates to a method, a system, equipment and a medium for detecting the locking quantity of an external locking turnout of a railway, and belongs to the technical field of track safety detection. The method for detecting the locking quantity of the external locking turnout of the railway comprises the following steps: detecting the locking quantity of the external locking turnout through a magnetic grid and a magnetic field inductive sensor; when relative movement occurs between the magnetic railing ruler and the magnetic field inductive sensor, the magnetic field inductive sensor can collect the number of passing magnetic railings, the collected number of the magnetic railings is analyzed and processed, then the movement direction and stroke are obtained in real time, and by monitoring the locking amount of the external locking turnout, the locking accuracy of the external locking turnout is improved. Therefore, real-time monitoring of the locking amount of the two sides of each traction point of the turnout switch rail is realized. And powerful data support is provided for field maintenance personnel. The method adapts to the outdoor turnout environment, the long-term stability is good, the reliability is high, and the measurement precision can reach +/-0.1 mm.

    本公开涉及一种铁路外锁闭道岔锁闭量检测方法、系统、设备和介质,属于轨道安全检测技术领域,所述铁路外锁闭道岔锁闭量检测方法通过磁栅和磁场感应传感器检测外锁闭道岔锁闭量;磁栅尺和磁场感应传感器之间发生相对运动时,磁场感应传感器会采集经过的磁栅数量,通过对采集到的磁栅数量进行分析和处理,进而实时获取运动方向和行程,其通过对外锁闭道岔的锁闭量监测,从而实现对道岔尖轨各牵引点两侧锁闭量的实时监测。为现场维护人员提供有力数据支撑。所述方法适应室外道岔环境,长期稳定性好,可靠性高,测量精度可达±0.1mm。
