The invention discloses a real-time detection system for the production operating parameters of an electrolyzer. The real-time detection system for the production operating parameters of the electrolyzer is characterized by comprising an industrial personal computer (7), multi-channel signal collectors (6) connected with the industrial personal computer (7), a cathode current distribution and cathode steel bar temperature detecting device (1), an electrolyzer shell temperature detecting device (2), an anode current distribution detecting device (3), a pressure transmitter (4) and a first thermoelectric couple (5). The real-time detection system for the production operating parameters of the electrolyzer can be used for detecting various parameters of the electrolyzer during production operation, transmitting the various parameters to the industrial personal computer in real time through the multi-channel signal collectors, and analyzing the detected parameters through the industrial personal computer. Compared with a traditional manual detection mode, detection results of the real-time detection system have no time difference, can really reflect each parameter of the electrolyzer during the production operation, and allows a staff to instantly know the operation conditions of the electrolyzer.
