The invention relates to the technical field of pipeline sealing, and particularly discloses a pipeline sealing intelligent monitoring and early warning method based on an internal high-pressure forming machine. Determining the pressure change characteristics of each preset measurement position in the sealed pipeline in the whole injection process; injection type pressurization is conducted on the sealed pipeline, and meanwhile pressure change data of each preset measurement position in the sealed pipeline in the actual injection process is monitored; based on the deviation degree between the pressure change data and the pressure change characteristics of all the preset measurement positions, analyzing a leakage evaluation value of each preset measurement position; leakage early warning is carried out based on all the leakage evaluation values; the method and the device are used for achieving pressure monitoring and leakage early warning in the injection type pressurization process of different injection flui
