The invention relates to the technical field of quantum nondestructive sensing, and provides a large lift-off rail crack quantum detection system which comprises a laser, a diamond NV color center, a microwave antenna, a microwave source, a photoelectric detector, a lock-in amplifier, a host, a magnetizer and a disturbance magnetic source. According to the system, the disturbance magnetic source is arranged near the leakage magnetic field, the magnetic field generated by the disturbance magnetic source and the leakage magnetic field are overlapped and interact with each other, a larger-range magnetic disturbance area can be obtained, the comprehensive magnetic field in the range also contains crack information of the surface of the rail, and the magnetic field in the magnetic disturbance area is sensed through the diamond NV color center; and the magnetic disturbance area has a larger range, so that the placement position of the diamond NV color center is wider, and the magnetic flux leakage detection with larger lift-off is realized.

    本发明涉及量子无损传感技术领域,方案为一种大提离铁轨裂纹量子检测系统,包含激光器、金刚石NV色心、微波天线、微波源、光电探测器、锁相放大器、主机、磁化器以及扰动磁源;本系统在漏磁场近处设置扰动磁源,扰动磁源产生的磁场与漏磁场相互叠加及相互作用,会获得一个更大范围的磁扰动区,此范围内的综合磁场同样蕴含铁轨表面的裂纹信息,通过金刚石NV色心感知磁扰动区内的磁场,也可进行铁轨裂纹检测,由于磁扰动区具备更大的范围,导致金刚石NV色心的安置位置更广,也即实现了更大提离的漏磁检测。
