The invention discloses a road abnormal parking detection method based on a geomagnetic sensor. The road abnormal parking detection method mainly solves the problems that an existing geomagnetic sensor is poor in cruising ability and low in parking detection precision. According to the implementation scheme, a plurality of geomagnetic sensor units integrated with solar cell panels are arranged on the two sides of a road along a lane line; judging whether a vehicle enters the detection range of the geomagnetic sensor by using a vehicle detection algorithm; when it is detected that a vehicle enters a sensor detection range, whether data are stable or not is judged by calculating the range of three-axis fusion magnetic field data; when the magnetic field data is stable, distinguishing abnormal parking and parking error detection by calculating the maximum value of the three-axis fusion magnetic field and the variable quantity of the X-axis magnetic field; and uploading the timestamp when abnormal parking is detected to the intelligent traffic cloud platform. The geomagnetic sensor unit is high in cruising ability, low in calculation complexity of parking detection and high in detection precision, and can be used for a road intelligent management system.
