The invention discloses a sensor for monitoring a steel rail crack state and a steel rail crack monitoring method, and relates to the technical field of monitoring sensors. The sensor for monitoring the crack state of the steel rail comprises an insulating layer, a sensitive grid and a protective layer, and is integrally adhered and fixed to the steel rail. Wherein the insulating layer is used for sticking and fixing the sensor on a steel rail and isolating the steel rail from a sensitive grid in the sensor. The sensitive grid is arranged on the insulating layer, and when the steel rail cracks under the action of external force, at least part of metal wires in the sensitive grid are broken, and the resistance of the sensor is increased. The protection layer is arranged on the sensitive grid electrode and isolates the sensitive grid electrode from the outside. The sensitive grid in the sensor can sensitively and correspondingly change along with the state change of the steel rail, so that the crack state of the steel rail can be reflected through the resistance state of the sensitive grid. The method can effectively monitor the crack state of the steel rail, and improves the real-time performance, accuracy and convenience of monitoring the crack of the steel rail.

    本发明公开了一种监测钢轨裂纹状态的传感器及钢轨裂纹监测方法,涉及监测传感器技术领域。监测钢轨裂纹状态的传感器包括绝缘层、敏感栅极和防护层,传感器整体与钢轨粘贴固定。其中,绝缘层用于将传感器粘贴固定在钢轨上,并对钢轨和传感器内的敏感栅极进行隔离。敏感栅极设置于绝缘层上,当钢轨在外力作用下出现裂纹时,敏感栅极中至少部分金属丝发生断裂,传感器电阻变大。防护层设置于敏感栅极上,将敏感栅极和外界进行隔离。本发明传感器中的敏感栅极能够敏感的随着钢轨的状态变化而相应变化,于是可通过敏感栅极的电阻状态反映钢轨的裂纹状态。能够有效的对钢轨裂纹状态进行监测,提高了钢轨裂纹监测的实时性、准确性以及便捷性。
