Intelligent power supply cathode protection testing device and method

The invention relates to an intelligent power supply cathode protection testing device. The device comprises a device shell, an intelligent tester and a solar cell panel, a connecting structure is arranged at the bottom of the device shell, and the device shell is mounted at the top of a cathode protection test pile through the connecting structure, so that the intelligent power supply cathode protection test device can be directly detached from a test pile body, the intelligent tester is arranged in the device shell, the intelligent tester is arranged at the top end of the cathode protection test pile, the cathode protection test pile is wrapped by the device shell, and the device is connected with the cathode protection test pile body. The intelligent power supply cathode protection testing device has the advantages that the interior of the intelligent tester is connected with a tested pipeline through the test pile body, and therefore the functions of unmanned measurement and wireless data transmission can
