用有限元软件对不同条件下机车信号传感器线圈铁芯中的磁感应强度进行了仿真 ,从而确定了传感器的几个重要参数。为降低外界干扰 (特别是邻线信号 )对机车信号传感器输出信号的影响 ,首次提出一种简单有效的提高机车信号传感器抗干扰性的方法。
The finite element software was used to simulate the magnetic flux density in the coil core of the locomotive signal sensor under different conditions, and several important parameters of the sensor were determined. In order to reduce the influence of external interference (especially adjacent signal) on the output signal of locomotive signal sensor, a simple and effective method to improve the anti-interference of locomotive signal sensor is proposed for the first time.
