Cathode protection potential detection system for buried pipeline

The invention provides a buried pipeline cathode protection potential detection system which comprises a processing module, a pipeline potential measurement module, a copper sulfate reference electrode and a temperature measurement module, and the pipeline potential measurement module, the copper sulfate reference electrode and the temperature measurement module are connected with the processing module. The copper sulfate reference electrode is arranged in soil above the buried pipeline and is used for providing a reference end potential, the temperature measuring module is used for measuring the environment temperature of the soil, and the processing module is used for obtaining a potential compensation value of the copper sulfate reference electrode according to the environment temperature; and the processing module is also used for obtaining the cathode protection potential of the buried pipeline according to the measuring end potential, the reference end potential and the potential compensation value.
