The utility model relates to an intelligent test pile to protect cathode of gas and oil pipeline, which comprises a marking pile, a pile holder and a protective potential detector. Wherein, the marking pile is cylindrical or rectangular and bottom girth is more than the top girth. In addition, the pile holder is round or rectangular. The protective potential detector is arranged in the pile holder. Two terminals posts are arranged around the pile holder for the protective potential detector, one of which is connected with the probe and the other is connected with measuring point of the monitoring pipeline. R-F electrode is available at the center of the marking pile and is slightly exposed out of the top of marking pile. The electrode is connected with GPRS communication module circuit of the protective potential detector. GPRS communication module interface is accessible on the protective potential detector and is directly connected with the onsite laptop for data collection. Dry battery and storage battery are prepared in the pile holder to realize dual-way power supply. Storage battery recharging interface is arranged on the top of the marking pile. Test data can be transmitted to remote end or to the onsite portable laptop.
