Summary:The invention provides a method and device for judging the offline state of a high-temperature pipeline, electronic equipment and a storage medium, and the method comprises the steps: obtaining an acoustic emission waveform signal and an acoustic emission characteristic parameter in the offline acoustic emission monitoring data of the high-temperature pipeline, and recognizing an acoustic emission characteristic waveform signal corresponding to the acoustic emission waveform signal, based on the confidence range of the standard waveform signal corresponding to the historical acoustic emission characteristic waveform signal, the acoustic emission characteristic waveform signal is screened, a crack initiation point corresponding to the high-temperature pipeline is determined, and based on a corresponding outlier and a time proportion threshold value when the historical acoustic emission characteristic parameter is abnormal, the acoustic emission characteristic parameter is screened, and the crack initiation poi
