Before launching the inspection tool, the ground tracking personnel shall select the set point and place the AGMs. During the run,when the ILI tool passes through the pipeline directly below the AGMs, the AGMs can be activated by the permanent magnet installed on the ILI tool. AGMs receives the magnetic signal in real time and stores it. At the same time, the activation information and location information can be uploaded to the server through GPRS function. The user can use the handheld terminal or PC terminal to obtain the relevant information of the AGMs for waveform preview, auxiliary identification, ILI tool route drawing and running speed evaluation
