Intelligent Pig Tracking System which follows the principle of vibration and infrasonic transmission. This is a new kind of intelligent pig tracking system that engin-
eer can gain the information of pig’s operation state without installing signal transmitter.

Intelligent Pig Tracking System consists of the Pig Tracking Tools & Pig Tracking Software which follows the principle of vibration and infrasonic transmission, that is: as the pig is moving inside along the pipeline, it will generate the sound wave by vibration,as the wave is captured by tracking tool’s highly sensitive sensors. At the same time, software is able to compute the pig’s state of motion information including position, velocity etc. by AI algorithm, then people can know the information by PC & mobile. Thus, this is a new kind of intelligent pig tracking system that people can gain the information of pig’s operation state without installing signal transmitter.
