The present invention relates to the technical field of electrochemical detection, in particularly to a method for distinguishing between quality control liquid and real sample in an electrochemical test system with recognition device controller and recognition system. The method includes: (1) applying an AC voltage signal to the electrode surface(s) of an electrochemical test strip, (2) measuring the AC impedance angle (phase angle) value between working electrode and reference electrode after drawing a test sample into the fluid chamber of an electrochemical test strip, (3) automatically judging the test sample as quality control liquid or real sample according to the AC impedance angle value. The method provided by the invention can automatically distinguish between quality control liquid and real sample in an electrochemical test system, simplifying the operation steps of quality control, avoiding the misoperation under manual quality control mode, and improving the accuracy and reliability of measurement results.
