The invention provides a permanent magnet track magnetic field irregularity detection system. The system comprises a permanent magnet track, a sensor support connected with a driving mechanism arranged above the permanent magnet track, a Hall sensor array installed on the sensor support, a data acquisition unit in communication connection with the Hall sensor array, and an upper computer in communication connection with the data acquisition unit, wherein the Hall sensor array and the permanent magnet track are mutually spaced; the sensor support is used for following the driving mechanism to walk along the extension direction of the permanent magnet track; the Hall sensor array is used for acquiring magnetic field intensity data of the permanent magnet track according to a preset acquisition period; the data acquisition unit is used for receiving the magnetic field intensity data transmitted by the Hall sensor array and transmitting the magnetic field intensity data to the upper computer; and the upper computer is used for determining whether the magnetic field intensity of the permanent magnet track is normal or not according to the magnetic field intensity data and a preset magnetic field intensity threshold value. The smoothness of the magnetic field of the permanent magnet track can be accurately detected, and the running safety of a maglev train is guaranteed.
