The invention relates to a direction angle measuring device based on an active magnetic field. The direction angle measuring device comprises a controller, a magnetic field generator, a magnetic resistance sensor and a power source, wherein the controller is in control connection with the magnetic field generator and the magnetic resistance sensor respectively; and the power source is electrically connected with the controller, the magnetic field generator and the magnetic resistance sensor respectively. The direction angle measuring device based on the active magnetic field adopts the magnetic field generator and the magnetic resistance sensor with high performance, the relative change of the starting and closing of the magnetic field generator is measured, measuring errors caused by the change of an earth magnetic field and the interference of an external magnetic field are eliminated, and the direction angle measuring accuracy is increased. 本发明涉及种基于有源磁场的方向角测量装置，所述方向角测量装置包括：控制器、磁场发生器、磁阻传感器以及电源；所述控制器分别与所述磁场发
