Buried steel pipeline forced current intelligent cathode protection system

The invention provides a buried steel pipeline forced current intelligent cathode protection system, and relates to the technical field of pipeline corrosion protection, and the system comprises an upper computer monitoring station which is in communication connection with a plurality of synchronous interrupters and a plurality of data acquisition instruments which are respectively connected with all positions along a buried steel pipeline; each synchronous interrupter is connected in series between the buried steel pipeline and a potentiostat, and the potentiostat obtains a reference signal in real time and calculates an output parameter; the synchronous interrupter sends the output parameters of the potentiostat to the upper computer monitoring station; each data acquisition instrument is respectively connected with a natural potential check piece, an alternating-current corrosion test piece and a second reference electrode which are buried underground, and is used for acquiring cathode protection parameter
