| description | The invention discloses a data acquisition method for pipeline magnetic flux leakage internal detection. The method comprises the following steps: monitoring acceleration data and angular velocity data acquired by an inertial sensor in a magnetic flux leakage detector in real time; judging whether the magnetic flux leakage detector is in a static state according to the acceleration data and the angular velocity data; if the magnetic flux leakage detector is in the static state, controlling a probe in the magnetic flux leakage detector to be in a dormant state without collecting magnetic flux leakage data until the magnetic flux leakage detector is changed from the static state to the moving state; and if the magnetic flux leakage detector is in the moving state, the probe is kept to continuously collect the magnetic flux leakage data of the pipeline. Repeated collection of useless data and occupation of the useless data on the storage space are avoided, reduction of energy and meaningless loss of the storage |
