The invention discloses a turnout action whole-process monitoring method and device based on magnetic grid measurement, and the related method comprises the steps: respectively installing double magnetic grid rulers on a main indication rod, an auxiliary indication rod and a friction coupler, and setting a magnetic sensor group in a set distance of each double magnetic grid ruler; the double-magnetic-grid ruler comprises two magnetic grid rulers with different numbers of magnetic poles, and each magnetic grid ruler is provided with a plurality of N magnetic poles and S magnetic poles alternately. When the turnout acts, the corresponding magnetic sensor groups are used for respectively reading the number of the two magnetic poles in the corresponding double magnetic railing rulers on the main and auxiliary indication rods, and the absolute positions of the main and auxiliary indication rods are determined according to the number difference value of the two magnetic poles, so that the relative positions of the main and auxiliary indication rods are obtained; the absolute positions before and after rotation are measured by the magnetic sensor group and the double-magnetic grid ruler on the same friction coupler, the relative distance after rotation is obtained, and the frictional resistance is further determined. According to the scheme, the turnout gap and frictional resistance can be accurately mastered, pre-repair can be achieved, and the service life of the point switch is prolonged.
本发明公开了一种基于磁栅测量的道岔动作全过程监测方法及装置,相关方法包括:在主副表示杆以及摩擦联结器上分别安装双磁珊尺,在每一双磁珊尺设定距离内设置磁传感器组;双磁珊尺包含两条磁极数目不同的磁栅尺,每一条磁栅尺上均为且交替设有多个N磁极与S磁极;在道岔动作时,通过相应的磁传感器组各自读取主副表示杆上对应双磁珊尺中两条磁极的数量,并通过两条磁极的数量差值确定主副表示杆各自的绝对位置,进而得到主副表示杆的相对位置;同样的摩擦联结器上磁传感器组与双磁珊尺,测量出转动前后的绝对位置,得到转动后的相对距离,进而确定摩擦阻力。上述方案能够准确掌握道岔缺口和摩擦阻力,能够实现预测修,并延长转辙机的使用寿命。
