Intelligent test pile is an essential device in pipeline cathodic protection intelligent detection management system. It is mainly used for the detection of cathodic protection effect and operating parameters. Generally, one test pile is set along 1 ~ 2km of pipeline.

The intelligent test pile automatically collects the data of pipeline protection potential, corrosion current, pipeline spontaneous potential, anode spontaneous potential and battery voltage of the equipment at a regular time every day, and uploads the data to the cloud server regularly through the 4G/ NB-iot network.

Cloud server installed on the pipeline cathodic protection intelligent monitoring and control system software, the software with B/S (browser/server) structure design, to essentially a database to store huge amounts of data, provides the electronic map, data display, the limit alarm, data query and statistics, analysis function, support for computer and mobile phone APP remote access.

The intelligent test pile is divided into two parts: the bolt body and the protective cover. The battery-powered intelligent monitor is installed in the protective cover to realize the functions of automatic data collection, automatic line switching, regular data uploading, and timely alarm of anomalies.
