The intelligent test pile consists of a marker pile, pile base, and protective potential detector. The marker pile is cylindrical or rectangular with a bottom circumference greater than the top circumference. The pile base is circular or rectangular and houses a protective potential monitoring instrument. Two terminals for the monitoring instrument are located around the base, one connected to a monitoring probe and the other to a monitoring point on the monitored pipeline. The center of the marker pile features a receiving/transmitting electrode slightly protruding from the top. This electrode is connected to the GPRS communication module circuit within the protective potential monitoring instrument. An interface for the GPRS communication module is provided on the monitoring instrument, which connects directly to a laptop on-site. The pile base is powered by two sources: dry batteries and a rechargeable battery, with a charging interface for the rechargeable battery on the top of the marker pile. The circuit is composed of a testing probe, pipeline protection potential, potential sensor, potential transmitter, sampling control unit, memory, GPRS communication module, battery power supply, and MOSFET switches. The testing probe, pipeline protection potential, potential sensor, potential transmitter, sampling control unit, and GPRS communication module are sequentially connected. The sampling control unit is connected to the memory, the battery power supply is connected to the MOSFET switches, and the MOSFET switches are connected to both the sampling control unit and the GPRS communication module.

The intelligent test pile is divided into two parts: the shaft and the protective cover. Inside the protective cover, a battery-powered intelligent monitoring device is installed, which achieves functions such as automatic data collection, automatic line switching, scheduled data upload, and timely alarm for anomalies.
