1. A system for monitoring internal corrosion of a pipeline based on radio-frequency identification (RFID), comprising:
a magnetizing device;
a RFID tag sensor; and
a reader;
wherein the magnetizing device is placed on the pipeline, and comprises an armature, a first permanent magnet, a first pole shoe, a second permanent magnet and a second pole shoe; the first pole shoe and the second pole shoe are arranged on an outer wall of the pipeline; the first permanent magnet is located above the first pole shoe, and is fixedly connected to the first pole shoe; the second permanent magnet is located above the second pole shoe, and is fixedly connected to the second pole shoe; the armature is located above the first permanent magnet and the second permanent magnet; one end of the armature is fixedly connected to the first permanent magnet, and the other end of the armature is fixedly connected to the second permanent magnet;
the RFID tag sensor is placed on the pipeline, and located on the same side as the magnetizing device; and
the reader is in wireless communication connection with the RFID tag sensor through a reader antenna.
