Metabolin continuous monitoring method and device

The invention provides a method and a device for continuously monitoring metabolites. The device comprises a flow cell, sensing equipment, analysis equipment and a detection circuit group. Wherein the detection circuit group comprises at least one detection circuit, each detection circuit is used for detecting fermentation liquor in a single fermentation tank, the flow cell is arranged on the detection circuit, and the sensing equipment is arranged in the flow cell. Specifically, the detection line is used for guiding fermentation liquor in the fermentation tank into the flow cell and guiding the detected fermentation liquor back to the fermentation tank; the sensing equipment is used for detecting the fermentation liquor in the flow cell to obtain detection data; and the analysis equipment is used for acquiring the detection data from the sensing equipment and analyzing the detection data to obtain a detection result. The device is used for detecting the fermentation liquor instead of manpower, so that the d
