The utility model discloses a portable multi-channel buried pipeline stray current detector based on a mobile terminal. The portable multi-channel buried pipeline stray current detector based on the mobile terminal comprises a plurality of channels, a potential acquisition module, a relay, an AD conversion module, a processor, a power supply module, a data storage module, a data transmission module, an interface and a change-over switch. A rapid general survey mode and an accurate measurement mode can be selected; the detector can be placed in a test pile, long-time real-time monitoring of several months can be realized through the equipped high-capacity lithium battery, multiple detectors are used at each monitoring point at the same time, and stray current monitoring coverage of a whole pipeline or a whole area can be realized. A plurality of detectors are used at a plurality of monitoring points at the same time, so that the stray current of the whole pipeline or the whole area can be rapidly detected, and
